We are currently witnessing the second quantum revolution and with it the advent of quantum technological devices for information processing purposes. Understanding these systems and their capabilities as well as developing robust algorithms for them, requires a fundamental understanding of complex quantum many-body systems as well as ways to characterize their properties efficiently. Within this course, we will help the participants to obtain proficiency in all of these aspects of quantum theory. A tentative list of topics includes:

- Entanglement/Non-Locality
Lecture 1: States, Measurement, Tensor Product, Maximally Entangled State
Lecture 2: Tensor Product (contd.), Density Matrices, Reduced States, Entropy, Entanglement Entropy.
Lecture 3: Bell-inequalities, Bell’s Theorem, Non-local Games/Protocols.

- Quantum Spin-System
Lecture 1: Spin Hamiltonians, Spin-½ Heisenberg Model, SU(2), Ground States, Ground State Energy
Lecture 2: Free Energy, Thermodynamic Limit, Thermal State
Lecture 3: Symmetry Breaking, Mermin-Wagner
Lecture 4: AKLT, Matrix Product States

For each of these topics, we will provide introductory lectures to get students acquainted with the topics before entering into the in-person phase, where experts and practitioners of these fields will give further insight.

Learning Outcome:

The goal is to provide the students with a blended learning approach to the course content on the mathematics of quantum theory with special emphasis on complex quantum many-body systems and quantum information theory. The main intended learning outcomes include an overview of the latest developments in those fields. Furthermore, the course will help the participants to develop competencies to engage in self-organized cross-university and interdisciplinary collaborations via online group work as well as to give and receive peer-feedback on results. Inviting external experts in the field will also give young researchers in the field the opportunity to grow their professional network considerably.

In the academic world, clear, concise, and well-written texts play an important role in convincing journal editors and conference organisers to accept a paper for review and publication, or to invite a researcher to present at a conference. This workshop supports PhD students and novice researchers who need to produce scientific papers in English. Providing participants with strategies to write short texts efficiently and effectively, it also focuses on standards of professional papers aimed at Anglo-Saxon or international research communities. It enables participants to organise ideas and structure texts effectively, to present their own and other researchers‘ findings and opinions appropriately, and to use correct terminology and vocabulary.

During the workshop, participants work with their own texts as well as with examples from their own disciplines that they bring along and consider to be particularly well written. They discuss features of good scientific papers and are equipped to use adequate language in different genres and for different audiences. In addition, they receive peer feedback on their own drafts. All exercises empower them to produce clearer, and more correct, concise, and reader-oriented papers.

The two-day workshop covers the following topics:

- taking inventory: participants‘ strengths and challenges in writing scientific papers in English
- a brief introduction to research and writing processes
- using text analysis to become a better writer
- reporting findings, ideas, and opinions professionally and adequately
- making yourself understood: principles of clear and concise writing
- structuring ideas, organising texts: transitions, connectives, & co.
- working effectively with co-authors and constructive text feedback
- useful online and offline resources

On the internet, video formats have long conquered the world. YouTube has long since overtaken television, especially among the younger generation, and many people move naturally in the world of short videos. In science, however, a large part of the community still shies away from using this medium.

In this workshop we will discuss the basics of (short) video production from the idea to the final upload. More importantly, we will shoot our first videos and gain our own experience with the medium of science video. In particular, we will also address the type of equipment needed and options for each budget.

Topics (selection)

- Equipment for video production
- Basics of video storytelling
- Video production from start to finish
- Best practice in recording
- Introduction to video editing software
- Upload to popular platforms

The possibility to record video formats should be given. A smartphone is sufficient for this purpose. Essential video equipment (light, audio and video hardware) will be provided.

Target group

This workshop is designed for doctoral candidates with previous presentation experience.

Objectives

"Wow, that presenter is so good in front of an audience. If only that were easier for me!" Being a good speaker is often just a question of developing a set of skills and techniques. The use of voice and body language, an effective presentation structure and the dynamic use of language require awareness and practice. The workshop helps to identify and explore these requirements, from self-reflection to self-assurance and long-term excellence.

Description

This seminar provides participants the opportunity to improve their conference presentation skills. Constructive feedback from the trainer and group members give the speaker a healthy amount of input while practicing new ideas and techniques to enhance the quality of their speech and overall impact of the talk.

Participants will be required to prepare a 3 to 5 minute overview of their work; the use of slides is optional. This will provide a basis for applying the practical aims of the workshop.

Throughout the two-day workshop, participants will be guided through interactive exercises to improve non-verbal communication, improve the ability to listen and react generously, and to integrate focusing techniques, which empower the speaker. Attention will also be given to structural and language aspects to improve clarity and flow of the talk.

It’s far more than “just” a presentation: defending your thesis is the last (and one of the biggest) challenges in your academic qualification – and it doesn’t only require well-prepared content. This workshop addresses aspects of the defense related to communication and presentation. We will work on participants’ body language as well as on strategies for convincing argumentative and rhetorical positioning during the disputation. A significant portion of the workshop will be devoted to simulated defenses and evaluations of the performances.

Persistent Homology for Detecting the Topology of Single-Cell Data
[]
Talk
Speaker: Sebastian Damrich • Department of Data Science, Hertie Institute for AI in Brain Health, University of Tübingen
Location: Mathematikon • Seminar Room Statistics 2/104 • Im Neuenheimer Feld 205, 69120 Heidelberg
ECTS: 1 for 5
After the talk, we invite everyone to stay for discussions as well as for tea, coffee and cake.

Single-cell RNA-sequencing records the expression values of thousands of genes in individual cells, making the study of cell functionality and development possible at high resolution. To understand the structure of single-cell data on a global level, topological descriptors, such as the presence of loops or voids in the data, are useful. For instance, loops might challenge the assumption of hierarchical cell development or be indicative of missing data in datasets of fully differentiated cells. The established computational tool for detecting the topology of point clouds is persistent homology. However, single-cell data is high-dimensional and notoriously noisy. We show that in high dimensionality traditional persistent homology becomes very sensitive to noise and fails to detect the correct topology. The same holds true for existing refinements of persistent homology. As a remedy, we find that spectral distances, such as diffusion distance and effective resistance, allow persistent homology to detect the correct topology even in the presence of high-dimensional noise. In particular, persistent homology with spectral distances can robustly detect the correct topology of single-cell data.

In this talk, I will venture a glimpse into the future of cutting-edge numerical methods and software for computational fluid dynamics (CFD) for many aerospace applications. While established, off-the-shelf commercial solutions for a broad range of applications exist, the current push towards fundamental changes in the fields of energy generation and transport necessitates computational tools that can keep pace and facilitate discovery through computation.
This talk will give an overview of the ingredients of modern simulation software for CFD, in particular for multi-scale, multi-physics and multi-fidelity problems. Among these are high-order discretization schemes that can adapt locally in space and time to the underlying resolution requirements and thus combine accuracy and robustness. While the potential of leveraging data-driven approaches has become apparent, I advocate for a shift from a purely data-driven to a data-informed approach, which combines both machine learning models (ML) and classical solution schemes consistently. Last but not least, modern discretization methods and ML/CFD hybrid schemes must produce efficient and reliable results. For this, GPU-parallelization and an incorporation of the FAIR principles into the simulation stack must be part of the next generation CFD solvers.

This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time.
You will also learn and practice the basic concepts of project management – a prerequisite in industries and research institutions.

Working as a PhD student you have the challenging task of developing research findings and write you doctoral thesis within three years. This alone is a demanding job. In addition, it is vital to the scientific process that your findings are presented to the scientific community. For most PhD students this is the first big project in their professional life and it could have a crucial impact on their future professional career. PhD students are highly motivated when they start their PhD studies but may underestimate the need for professional management for this three-year project "doctoral thesis".

This seminar demonstrates how to approach the doctoral thesis in a professional way. Project management tools and techniques are used, tailored to the specific situation of PhD students. You will learn how to set a project vision, define clear objectives, gain buy-in from your supervisor and other colleagues in your group, and how to develop a project plan, which is structured and at the same time flexible enough to easily adjust to unexpected findings. You will establish a "controlling cycle" which helps you to recognize risks and problems as early as possible, and you will learn how to manage critical situations and deal with ups and downs. Furthermore, networking with colleagues, supervisors and other people are important topics of this seminar.

Throughout the seminar, you will work on your own doctoral thesis and share your experience with others. This seminar is most beneficial for PhD students who are in the early phases of their doctoral thesis. At the end of the seminar you will have established a strategy on how to approach your own doctoral thesis. During the follow-up REVIEW we will share experience and best practices and deal with open questions from the first module.

This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time.
You will also learn and practice the basic concepts of project management – a prerequisite in industries and research institutions. Working as a PhD student you have the challenging task of developing research findings and write you doctoral thesis within three years. This alone is a demanding job. In addition, it is vital to the scientific process that your findings are presented to the scientific community. For most PhD students this is the first big project in their professional life and it could have a crucial impact on their future professional career. PhD students are highly motivated when they start their PhD studies but may underestimate the need for professional management for this three-year project "doctoral thesis".

This seminar demonstrates how to approach the doctoral thesis in a professional way. Project management tools and techniques are used, tailored to the specific situation of PhD students. You will learn how to set a project vision, define clear objectives, gain buy-in from your supervisor and other colleagues in your group, and how to develop a project plan, which is structured and at the same time flexible enough to easily adjust to unexpected findings. You will establish a "controlling cycle" which helps you to recognize risks and problems as early as possible, and you will learn how to manage critical situations and deal with ups and downs. Furthermore, networking with colleagues, supervisors and other people are important topics of this seminar.

Throughout the seminar, you will work on your own doctoral thesis and share your experience with others. This seminar is most beneficial for PhD students who are in the early phases of their doctoral thesis. At the end of the seminar you will have established a strategy on how to approach your own doctoral thesis. During the follow-up REVIEW we will share experience and best practices and deal with open questions from the first module.

This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time.
You will also learn and practice the basic concepts of project management – a prerequisite in industries and research institutions.

Navigating the challenges of the global COVID-19 pandemic required strategic decisions tailored to each country's unique circumstances. In less developed nations, the threat of overwhelming hospital capacity was especially severe. Rather than building scenarios based on mathematical models, our team used a dynamic forecasting approach. We developed a series of models that provided 4-week probabilistic forecasts, complete with uncertainty quantification. These forecasts, crucially informed by real-time data, predicted the demand for hospital beds and ventilators, which served as the backbone for decisions and public policies adopted by federal health authorities in Mexico from April 2020 to January 2022. The journey was a challenging one. An incompletely characterized virus and the unpredictable dynamics of societal behavior made crafting a useful model difficult.

In this talk, I will present a retrospective of these models and critically review their objectives, successes, and limitations. Our methodology and modeling decisions will be presented, from the intricacies of data used for model fitting to the balance between model complexity and parameter identifiability. The predictive power and performance of our models will also be reviewed. Beyond the algorithms and forecasts, I'll share our experiences collaborating with health authorities and communicating with the general public. Discover the highs and lows, the challenges faced, and the insights we gained.

AMMICO, an AI Media and Misinformation Content Analysis Tool: Communication research meets software development
[]
Talk
ECTS: 1 for 5
No registration required!

This event is organized by the Heidelberg Center for Digital Humanities (HCDH) and the Scientific Software Center (SSC).

This presentation consists of two parts and perspectives.

PD Delia Dumitrescu from social/political sciences will speak about communication research using a multi-country, multi-language data set containing COVID-19 social media disinformation posts. Delia will present the initial difficulties related to the dataset and how she approached the Scientific Software Center for support. This support resulted in AMMICO (AI Media and Misinformation Content Analysis Tool): AMMICO is a publicly available software package written in Python 3, whose purpose is the simultaneous evaluation of the text and graphical content of image files. After describing the software features, Delia will provide an assessment of its performance using the social media disinformation posts. This part will conclude by highlighting the tool’s advantages for communication research and by discussing further development ideas.

In the second part of the talk, Dr Inga Ulusoy from the Scientific Software Center (SSC) will speak about the role of the SSC in this project. The initial consultation evolved into a software development project of the SSC. Inga will describe how the project and communication was structured and how the software was designed to fit the needs of the researchers. In the end, Inga will demonstrate how AMMICO can be utilized in further research projects, and conclude by summarizing the ways the SSC can support research projects through research software development and the implementation of software engineering best practices.

"Many cases of research misconduct come to light only because someone dares to blow the whistle. But how do you do that? Will your institution take your suspicions seriously? Will they protect you? Would approaching the press be effective—and can you trust a journalist? How do you make sure your whistleblowing doesn’t hurt your career? And how do journalists handle these sensitive cases?

In this workshop, Swedish research fraud whistleblower Josefin Sundin and science journalist Martin Enserink will discuss what they learned from high-profile misconduct cases. Joachim Kirsch, research integrity ombudsman for Life Sciences at the University of Heidelberg, will discuss the institutional perspective.

Neuroscience-inspired artificial intelligence aims to develop AI systems that learn and act in ways similar to the human brain. This talk will discuss some recent advances in this field, starting with successful examples of neuroscience-inspired machine learning approaches, such as Vector Symbolic Architectures, Hierarchical Temporal Memory, and FlyHash. We also outline recent studies on the similarity of processing in transformers, the deep learning models at the core of Large Language Models, and the structure of brain activities recorded with fMRI during listening tasks. Finally, we discuss the fundamental differences between backpropagation and likely biological learning mechanisms, and explore alternative learning algorithms such as Geoffrey Hinton's forward-forward algorithm. We conclude by examining the implications of these findings for open problems in AI such as one-shot learning, model robustness, and explainability.

Numerical simulations are widely used as a third pillar besides experimental and theoretical investigations in many sciences such as physics and chemistry as well as engineering science. It requires the development of robust and efficient numerical methods for the resolution of the underlying physical laws that arise often in form of partial differential equations (PDEs). In this talk, I will describe two interdisciplinary stories. While illustrating the key-ideas of the theory and methods, I will also highlight the occasions where not only the mathematical tools have been successfully developed and transferred to the application but also where the interdisciplinary interactions raised new mathematical questions and triggered new answers and theories in mathematics. From the application viewpoint, this talk will touch upon implicit solvation models and Born-Oppenheimer molecular dynamics but the methods rely on various and divers mathematical concepts from Grassmann manifolds to descriptors from machine learning and perturbation theory.

Location: Mathematikon • Im Neuenheimer Feld 205, 69120 Heidelberg (Exact room will be announced on the SSC website two weeks prior to the course)
Registration: Please register via this form
ECTS: 1
This is a one day course. The first half of the day covers the basics of the Unix Shell, the second half covers Version Control with Git.

The latest information and a registration link are available on the course website.

Prerequisites:

No prior knowledge by the participants is necessary to participate in this course and it is intended for all scientific audiences. Participants are required to bring their own laptops to work on during the course. Network access (e.g. through Eduroam) is recommended.

Summary:

The Unix shell is a powerful tool that allows people to do complex things with just a few keystrokes. More importantly, it helps them combine existing programs in new ways and automate repetitive tasks so they aren’t typing the same things over and over again. Use of the shell is fundamental to using a wide range of other powerful tools and computing resources. The course will include hands-on live coding sessions where participants exercise the learned commands on their own computers.

Version control is the lab notebook of the digital world: it is used to keep track of what was done and to collaborate with other people. Its use is the state of the art in software development projects of all scales. However, it is not limited to software: books, papers, small data sets, and anything that changes over time or needs to be shared can and should be stored in a version control system. The course will include hands-on live coding sessions where participants exercise the learned commands on their own computers.
Learning Objectives

After the course participants will:

- Have a fundamental understanding of how and why to use the Unix Shell
- Be comfortable with handling files and directories using the command line
- Have experience with advanced usage of the shell e.g. loops, pipes, redirects etc.
- Know how to write their workflows as reusable shell scripts
- Understand the benefits of using version control
- Understand basic git terminology
- Have a good working knowledge of common tasks in Git
- See how Git repositories can help them to move towards practicing Open Science

This talk is brought to you by Lorenzo Masia.

Mutual predictability is the key to interaction. Or in simpler terms: "experience makes teamwork". Of course, prediction isn't all that simple. We'll look at "generative AI", but without the hype, and see how we use that to learn the dynamics of complex stochastic systems, use that to predict -- and control. And give some examples, in robotics and beyond, of where this can be used.

Collecting, processing and analyzing data are central activities for virtually every researcher. Topics like data sharing and data publication are becoming increasingly important. Nevertheless, many research projects lack a structured and well-organized data management. This course is meant to give a general, discipline-independent introduction into various topics central to an efficient management of research data with a special focus on questions related to data archiving and data sharing. Both are central aspects of good scientific practice. Archiving and long-term preservation of research data are prerequisites for the scrutiny of scientific results based on the analysis of this data. Data sharing on the other hand increases transparency of research results and enables possible re-usage of data for new research questions, in combination with additional data sets and in interdisciplinary contexts.

School
Location: Copenhagen, Denmark
Registration: Please register on the event website
ECTS: 2
The course aims at PhD and advanced Master's students in statistics, probability theory, and econometrics, or with a background in the aforementioned areas such as physics, and geosciences.

This summer school is part of Flagship 3 of the 4EU+ European University Alliance, a close partner of HGS MathComp. Please contact us for funding options through 4EU+ and HGS MathComp.

The understanding of the appearance of extremes in real-life time series (such as weather and climate observations, returns of stock prices, exchange rates, and stock indices, insurance claim data, failures in energy and social networks) requires suitable probabilistic models and their statistical analyses. Over the last 15-20 years such models and statistical tools have been developed under the assumption of serial dependence. They supplement classical extreme value analysis which deals with independent data.

The goals of the course are

- to introduce and discuss the recent developments of extreme value theory in the time series context. The main focus will be on heavy-tail phenomena, where extremes are particularly severe, and clustering effects when extremes appear in clumps, 

- to provide suitable statistical tools for analyzing the aforementioned phenomena,

- to provide relevant knowledge to graduate students about extreme behavior of random systems in contrast to their average behavior, 

- to learn about applications of extreme value theory from top experts in the field.

The course is practical of nature, with real-world data examples and focus on possibilities, limitations, and practical implementation. The open-source program R is used for the computations.

Prerequisites:

Participants are expected to have knowledge of basic statistics corresponding to a one-semester course. They are also expected to have at least basic experience with the R program.

No experience with R? Here is how you can prepare for the course:
• Join the preparatory Introduction to R course at the University of Copenhagen, August 24-25, 2023. The course fee is waived for you as a participant from a 4EU+ partner university. Please register using the form for employees (link at webpage), leave out details for payment but make a comment that you are from 4EU+. For travel funds, please contact us at hgs@iwr.uni-heidelberg.de
• Take a free online course, for example: Harvard University - Data Science: R Basics

Teaching methods:

The course is divided into six blocks (half days). Each block will consist of a mixture of presentations and hands-on exercises. In the presentations we take starting point in real-world datasets and scientific problems and discuss the relevant statistical methods. Focus is on the link between data and methods, implementation, and interpretation of results. Exercises will be practical, with exploration and analysis of real-world datasets. Participants are expected to use the statistical software environments R and RStudio for the exercises.

Teaching material:

The teachers will provide slides, programs/output from R Markdown, data, and exercises. Apart from this, notice that the book R for Data Science (https://r4ds.had.co.nz or https://r4ds.hadley.nz) is useful for data manipulation and visualization.

Nature-based Solutions for Tackling Global Health Challenges
[]
School
Location: Heidelberg University
Registration: Please register via this form
Link:
ECTS: 0
An interdisciplinary summer school to equip early-career scientists and practitioners with the main concepts and methods of researching and implementing Nature-based Solutions (NbS), including: theory, study design, data and modelling, financing, determining value and implementation as well as their application to the converging global challenges: climate change and pandemics.

Target Audience:
MSc. and PhD candidates as well as postdoctoral scientists and young researchers from a broad range of disciplines who have a strong motivation to apply NbS in their field of research or work.

Registration Deadline:
before July 26, 2023

In the 21st century, society faces multiple and highly interwoven global health challenges, linked to accelerating climate change, antimicrobial resistance, food and water insecurity, and an increasing number of infectious diseases. Threatening convergence, these health issues call for more effective and sustainable solutions to ensure that the global population continues to thrive. Scientists and researchers can massively contribute to discovering, co-designing, and evaluating these solutions.

In this context, Nature-based Solutions (NbS), while not yet commonplace, are increasingly gaining recognition alongside more conventional engineering solutions and healthcare interventions. The concept of NbS describes the innovative use of existing knowledge about natural systems to assist society in effectively addressing contemporary environmental, social and economic challenges while simultaneously providing ecological and health benefits. These win-win NbS include the management, restoration and protection of ecosystems, strategies for climate adaptation and mitigation and the greening of infrastructure.

The Summer School will explore the innovative potential of NbS to tackle two pressing global health challenges – climate change and pandemic prevention, which are highly interconnected and provide opportunities to design, apply and evaluate a range of win-win NbS to inform future policies based on scientific evidence.

The guest speakers will share their expertise and experience with the participants and will collaboratively work together on a capstone project, relevant to the development and presentation of a research project on NbS to tackle climate change and pandemics.The Summer School will promote interdisciplinary thinking and will encourage participants to bring examples of NbS beyond these two challenges for discussion to consider how to develop NbS that address concrete challenges and implement solutions in very diverse settings. As a result, the Summer School will allow participants to further connect, interact, and build a worthwhile network of expertise on NbS.

Advanced statistical methods are rapidly impregnating many scientific fields, offering new perspectives on long-standing problems. In materials science, data-driven methods are already bearing fruit in various disciplines, such as hard condensed matter or inorganic chemistry, while comparatively little has happened in soft matter. I will describe how we use multiscale simulations to leverage data-driven methods in soft matter. We aim at establishing structure-property relationships for complex thermodynamic processes across the chemical space of small molecules. Akin to screening experiments, we devise a high-throughput coarse-grained simulation framework. Coarse-graining is an appealing screening strategy for two main reasons: it significantly reduces the size of chemical space and it can suggest a low-dimensional representation of the structure-property relationship. I will briefly mention a biological application of our methodology that led to the discovery of in vivo active compounds. Finally, I will mention a number of ways machine learning can help fulfill the promise of connecting models at different scales.

Convolutional Neural Networks (CNN) are the current backbone of deep learning architectures in a wide range of applications which process array data, like 2D/3D images. Despite this overwhelming success of the application of CNNs in terms of qualitative (visual) results and classification test set accuracies, this talk will point out some servere inherent problems of CNNs regarding their insufficient signal processing capabilities.
While these “signal processing flaws” have been largely ignored as test accuracies on many problems have been increasing over many years, recent research showed that current models are highly vulnerable to even the slightest changes in input distributions. In our latest works [1-5], we showed that the missing “robustness” of CNNs is not only due to insufficient training data, but to a large extend is also caused by faulty operators and architectures which are failing to adhere to basic signal processing demands. The aim of this talk is to give an overview of the dominant problems in the context of image processing and analysis and discuss possible counter measures.

Machine-learning, which can learn to predict given labeled data, bares many promises for medical applications. And yet, experience shows that predictors that looked promising most often fail to bring the expected medical benefits. One reason is that they are evaluated detached from actual usage and medical outcomes.
And yet, test runing predictive models on actual medical decisions can be costly and dangerous. How do we bridge the gap? By improving machine-learning model evaluation. First, the metrics used to measure prediction error must capture as well as possible the cost-benefit tradeoffs of the final usage. Second, the evaluation procedure must really put models to the test: on a representative data sample, and accounting for uncertainty in model evaluation.

Challenges in Solving Large scale PDE-constrained Optimization
[]
Lecture
Speaker: Nagaiah Chamakuri • IISER, Thiruvananthapuram, India
Location: Mathematikon • Seminar Room B, Ground Floor • Im Neuenheimer Feld 205 • 69120 Heidelberg
ECTS: 0
Informatics for life represents an interdisciplinary alliance of cardiovascular physician scientist and computer scientists from the University of Heidelberg, University Hospital Heidelberg and the Heidelberg Institute for Theoretical Studies.

This talk presents a feasible study of optimal control techniques for cardiac defibrillation based on the bidomain-bath equations posed on a rabbit ventricle geometry. The bidomain model consists of a system of elliptic partial differential equations coupled with a non-linear parabolic equation of reaction-diffusion type, where a set of ordinary differential equations describes the reaction term, modeling ionic transport. Since ODEs describe the ionic currents in the tissue, the PDE part dominates the solving effort. Thus, it is unclear if commonly used splitting methods can outperform a coupled approach by maintaining good accuracy. The results will be presented in the first part based on comparing the coupled solver approach with commonly used splitting schemes to solve more sophisticated physiological models. Consequently, the novel memory-efficient computational technique will be demonstrated to solve the coupled systems of equations. In the second part, the optimal control approach for successful cardiac defibrillation will be shown based on minimizing a properly chosen cost functional depending on the extracellular current as input at the boundary of the bidomain-bath domain.

Second HBPMolSim Training Workshop on Tools for Molecular Simulation of Neuronal Signaling Cascades. This workshop is part of the EBRAINS RI trainings.

Registration deadline: 09.06.2023. This will be a hybrid event.

The human brain is one of the most complex and fascinating structures. It is still far from understood and therefore considered one the last biological frontiers. Its function is the result of intricate signal transmission networks and reactions occurring within and between neurons. To model and simulate such complexity, multiscale models are required that are aimed at reproducing brain function through a bottom-up approach, from the molecular to the whole brain level. This workshop will provide training in some of the computational tools developed in the Human Brain Project that enable brain simulation and modelling at the molecular and subcellular levels. This workshop is intended to offer an overview of these tools and their application and provide students and young researchers with the necessary theoretical background and practical experience to enable them to apply them in their own research. There will be a mix of lectures and practical session as well as discussions of case studies and the participants' own research problems.

About the speaker:

Anil Ananthaswamy is an award-winning science journalist and former staff writer and deputy news editor at New Scientist magazine. Currently, as a freelance journalist, he writes for Quanta, Scientific American, New Scientist and Nature, among others. His most recent book, Through Two Doors at Once was named one of Smithsonian's Favorite Books of 2018 and one of Forbes's 2018 Best Books About Astronomy, Physics and Mathematics. In 2023 Anil Ananthaswamy was selected as “Journalist in Residence" at at the Heidelberg Institute for Theoretical Studies (HITS).

In the early 1800s, Thomas Young performed a homespun experiment with a sunbeam split into two, and challenged our understanding of the nature of light. With the birth of quantum mechanics, starting in the early 1900s, this "double-slit" experiment—now done with individual particles—started challenging our ideas about the nature of reality. How can a single particle behave both like a particle and a wave? Does a particle, or indeed reality, exist before we look at it, or does looking create reality? Is there a place where the quantum world ends and the familiar classical world of our daily lives begins, and if so, can we find it? In the 1960s, Richard Feynman said that the deceptively simple double-slit experiment contains the "central mystery" of the quantum world. Even he would have been amazed at just how far physicists have pushed this experiment, and how it still continues to confound and challenge our intuitions about the nature of reality.

Abstract:

I will discuss our efforts to use machine learning (ML) to accelerate the computational tailoring and design of transition metal complexes for catalysis and metal-organic framework (MOF) materials in spaces of millions to tens of millions of materials. Traditionally, computational modeling with high-throughput screening based on density functional theory (DFT) has been employed for data generation either for direct discovery or when paired with regression ML models. I will describe how we have addressed some of the challenges of applying these workflows in regimes of scarce data. I will describe how we have achieved 1000-fold accelerated discovery of light-harvesting complexes, single-site catalysts, and energy storage materials. To accomplish this, we have quantified uncertainty using measures of the latent space to improve model confidence as well as to drive efficient global optimization workflows with multitask neural networks. I will also describe how we have leveraged natural language processing to extract, learn, and directly predict experimental measures of stability on heterogeneous MOF materials. I will also touch upon how we are beginning to overcome one chief limitation of accelerated catalyst discovery by using diffusion models to predict transition state structrues, the rate limiting step in conventional computational modeling of catalysts.

Location: Mathematikon • Lecture Hall, Ground Floor • Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: 0

The lecture will be held in German and English.

The emergence and transmission of pathogens that cause infectious diseases is an increasing threat in Europe, fueled by climate change, globalization, increasing international mobility, amongst many other broad societal and environmental transformations. Since the 2000s, The Upper Rhine Valley in Southwestern Germany has emerged as a hotspot for invasive Asian tiger mosquitoes with their populations persisting despite control and eradication efforts by local and regional administrations.

To address the growing public health risk endemic Asian tiger mosquitoes populations pose in relation to the spread of infectious diseases, it is critical that efforts are undertaken to evaluate the conditions contributing to the establishment of Asian tiger mosquitoes populations as well as how efforts to mitigate and respond to climate change may actually make local environments more suitable to these disease vectors amongst others.

Join professors from Universität Heidelberg to learn about these threats and the impacts of climate change and mobility on disease vectors such as mosquitoes. Speakers will address current research at Universität Heidelberg and its partner institutions as well as the citizen science initiative Mosquito Alert which is working to tackle invasive mosquito populations across the globe.

Abstract:
The world is changing rapidly, accelerating our need to understand how factors like climate, land use, and social structure affect the ecology of disease on a global stage. Interrogating these processes requires applying advanced analyses across broad datasets to ensure that results are generalisable and complexities are well-understood. However, often, disease ecology analyses take relatively coarse species-level approaches that are fraught with sampling biases and are restricted in their ability to inform finer-scale processes. Further, when these models are used to predict the disease consequences of global change they can be difficult to validate, reducing our confidence in their predictions.

In this talk, I present a series of analyses that we have used to identify macroecological trends of host-pathogen ecology and the changing structure of the global host-virus network, and our efforts to use them to predict elements of global change. I compare and contrast them with other finer-scale studies of disease dynamics that comprise most of the field of disease ecology, and I outline the ways we are attempting to move between these scales of investigation. Ultimately, I discuss the need for “bottom-up” mechanistic prediction of disease dynamics in novel systems, using fine-scale analyses to inform the most important global-scale problems.

This 4-day course offers a compact introduction to mathematical optimization. We invite researchers in non-mathematical fields as well as in mathematics to attend the classes.
The goal of the course is to enable the participants to recognize the characteristics of a given optimization problem, to understand its difficulties and limitations, and to choose suitable solution methods as well as to develop ideas on how to model problems from their own field as optimization problems.

We will focus on the following four categories of optimization problems:
day 1) unconstrained optimization
day 2) convex optimization
day 3) nonlinear optimization
day 4) infinite-dimensional optimization

For each of these problem classes, we will study meaningful examples, the relevant theory, and prominent solution algorithms. Every day consists of a 90-minute lecture part in the morning and a 90-minute hands-on exercise session in the afternoon.

Abstract:
First of all, we will define, and recall basic the properties of braids groups and connect them naturally with knot theory. Some of its applications in the hairstyles of African women will be presented. Secondly, we will share a cultural experience around one of the oldest African games well known as "African stones game".

Title: What Exactly is Infinity?
Speaker: Dr. Michael Winckler • HGS MathComp

Abstract:
The concept of infinity is hard to understand for humans. Counting finite sets is a natural concept, but understand what countably infinite sets are and that we can even investigate uncountably infinite sets is difficult to comprehend.

In this lecture we will start by comparing finite sets and establishing a rigorous method to compare sets in their size. Expanding this to infinite sets will help us to move forward and show that different levels of infinity exist. We will conclude the lecture by trying to visualize our results in drawing space-filling curves, thus experiencing that our notion of size does not easily extend to infinity.

ECTS: not yet determined

Having access to a powerful generative model allows for a wide range of downstream applications, such as probabilistic inference, sampling, data completion, density evaluation, outlier detection, etc. Diffusion models (DMs) are an emerging class of deep generative models that have demonstrated remarkable synthesis quality. DMs rely on a diffusion process that gradually perturbs the data towards white noise, while the generative model learns to denoise. A major drawback of DMs, compared to, for example, Generative Adversarial Networks, is that sampling can be relatively slow.

In this seminar, I will give an accessible introduction to DMs and present our work on critically-damped Langevin DMs (CLD) which is based on ideas from statistical mechanics. CLD can be interpreted as running a joint diffusion in an extended space, where the auxiliary variables can be considered "velocities" that are coupled to the data variables as in Hamiltonian dynamics. CLD significantly accelerates sampling compared to the original DM formulation, however, many further improvements can be made by borrowing ideas from the ODE solver literature.

Our brains are comprised of billions of neurons that form a complex network. This network is a result of both evolutionary optimization (fostering a modular arrangement including highly specialized areas) and our own experience (storing memories and skills by adapting connection strengths) and determines how we process sensory input to produce meaningful responses. Since neurons communicate with short electrical pulses only when necessary, they are extremely energy efficient. Given our worldwide increase in computing demand, there is thus a strong incentive to develop low-energy neuromorphic computing paradigms that mimic the working principles of the brain. But what are the relevant working principles of the brain? How does a neural network develop useful dynamics? In this seminar, I will present minimal principles to ensure stable collective neural dynamics from a statistical physics perspective, discuss how these can be used to tune network states to task requirements and show how they can be applied to neuromorphic computing. While I mainly focus on experience-driven self-organization, I will finish with some ideas to include evolutionary-driven architectures in the future.

The IWR Colloquium will be held as an in-person event at the Mathematikon. In addition it will be streamed via Zoom.

The large-data limit of the MBO scheme for data clustering

ECTS: not yet determined

The MBO scheme is an efficient algorithm for data clustering, the task of partitioning a given dataset into several meaningful clusters. In this talk, I will present the first rigorous analysis of this scheme in the large-data limit.
The starting point for the first part of the talk is that each iteration of the MBO scheme corresponds to one step of implicit gradient descent for the thresholding energy on the similarity graph of the dataset. It is then natural to think that outcomes of the MBO scheme are (local) minimizers of this energy. We prove that the algorithm is consistent, in the sense that these (local) minimizers converge to (local) minimizers of a suitably weighted optimal partition problem.
To study the dynamics of the scheme, we use the theory of viscosity solutions. The main ingredients are (i) a new abstract convergence result based on quantitative estimates for heat operators and (ii) the derivation of these estimates in the setting of random geometric graphs.
To implement the scheme in practice, two important parameters are the number of eigenvalues for computing the heat operator and the step size of the scheme. Our results give a theoretical justification for the choice of these parameters in relation to sample size and interaction width.
This is joint work with Jona Lelmi (University of Bonn).

Minicourse: Introduction to Mathematics of Deep Learning
Leonid Berlyand • Pennsylvania State Universtiy, USA
October 26-27, 2022 • 14:30 - 16:30

Abstract:
The goal of this minicourse of four lectures is to introduce basic concepts from deep learning in a rigorous mathematical fashion, e.g introduce mathematical definitions of deep neural networks (DNNs), loss functions, the backpropagation algorithm, etc. We attempt to identify for each concept the simplest setting that minimizes technicalities but still contains the key mathematics. This minicourse follows the upcoming book “Mathematics of Deep Learning: an introduction” by L. Berlyand and P.-E. Jabin. Publisher: De Gruyter (to appear).

Lecture 1. History, general perspective and basic notions of deep learning

In this lecture, we briefly discuss the general perspective of machine learning:
what is it and why study it? Next, we introduce the classification problem in a supervised learning context and then introduce the key concept of artificial neural networks (ANNs) as the composition of linear maps and nonlinear activation function followed by other basic definitions describing ANNs.

Lecture 2. DNNs and approximation theory

In this lecture, we discuss the universal approximation theorem describing the wide class of continuous functions which DNNs can be used to approximate. This theorem explains the extensive use of DNNs in classification problems. Next, we introduce the concept of training via the gradient descent algorithm which improves the approximate classifier by iteratively __learning__ from the dataset.

Lecture 3. Backpropagation & CNNs

We begin from introducing the notion of computational complexity. Next, we introduce the backpropagation algorithm which significantly reduces the computational cost of optimizing the loss function. This is done in the simplest one neuron per layer setting, which while not practical allows us to explain the concept without many technicalities. Finally, if time permits, we briefly discuss convolutional neural networks and their properties.

Lecture 4. Implementing DNNs and Training: a brief overview of Pytorch

This lecture will be presented by my co-author P.-E. Jabin (Penn State).

We present here a short and very basic introduction to Pytorch, in the context of classification of images. We assume passing familiarity with coding and with python in particular. Many further tutorials exist online and several can be found at https://pytorch.org/tutorials/

From the vision “Stability, Prosperity and Sustainability,” Thailand has adopted “Thailand 4.0” as a policy vision for economic development which aims at driving the country out of a middle-income towards a high-income economy. Underlying this is no other than an attempt to change from the current economic model towards an “innovation-driven economy”—i.e., transitioning from an industry-driven development to a technology-, creativity-, and innovation-driven development by consolidating as well as integrating various fields of knowledge. This, thus, necessitates deepening mathematical research on optimization and numerical methods as it plays a considerable role in providing solutions for a variety of problems including those in such areas as industry, finance, engineering, economics and agriculture.

Realizing the importance of research on optimization and numerical methods, the Department of Mathematics, Faculty of Science, King Mongkut’s University of Technology Thonburi—in cooperation with the Interdisciplinary Center for Scientific Computing (IWR), Heidelberg University, the Federal Republic of Germany, and along with the nationwide as well as the Southeast Asian regionwide network of universities including Walailak University, Prince of Songkla University (Pattani Campus), Chulalongkorn University, Silpakorn University, Mahidol University, Chiang Mai University, and King Mongkut’s University of Technology North Bangkok—will organize an international “Workshop on Computational Science 2022: Webinar on Optimization and Numerical Methods in Industries.”

This year, the Department will co-host the event with the Department of Mathematics, School of Science, Walailak University, and the Department of Mathematics and Computer Science, Faculty of Science, Chulalongkorn University.

Validity, Reliability, and Significance: A Tutorial on Statistical Methods for Reproducible Machine Learning
[]
Workshop
Speaker: Prof. Stefan Riezler & M.Sc. Michael Hagmann • IWR
Location: Mathematikon • Conference Room, Room 5/104, 5th Floor • Im Neuenheimer Feld 205 • 69120 Heidelberg
ECTS: 3

Scientific progress in machine learning is driven by empirical studies that evaluate the relative quality of models. The goal of such an evaluation is to compare machine learning methods themselves, not to reproduce single test-set evaluations of particular optimized instances of trained models. The practice of reporting performance scores of single best models is particularly inadequate for deep learning because of a strong dependence of their performance on various sources of randomness. Such an evaluation practice raises methodological questions of whether a model predicts what it purports to predict (validity), whether a models performance is consistent across replications of the training process (reliability), and whether a performance difference between two models is due to chance (significance). The goal of this tutorial is to provide answers to these questions by concrete statistical tests.

The tutorial is hands-on and accompanied by a textbook (Riezler & Hagmann: Validity, Reliability, and Significance: Empirical Methods for NLP and Data Science Synthesis Lectures on Human Language Technologies, Morgan & Claypool Publishers, 2022) and a webpage including R and Python code: https://www.cl.uni-heidelberg.de/statnlpgroup/empirical_methods/

In this talk I will present a geometric multilevel optimization approach choosing as case study a regularised inverse problem. In particular, the approach is motivated by variational models that arise as the discretization of some underlying infinite dimensional problem. Such problems naturally lead to a hierarchy of discretized models. We employ multilevel optimization to take advantage of this hierarchy: while working at the fine level we compute the search direction based on a coarse model. By utilising concepts of information geometry in our formulation, we propose a smoothing operator that only uses first-order information and incorporates constraints smoothly. We show that the proposed algorithm is well suited for ill-posed reconstruction problems and demonstrate its efficiency on several large-scale examples.

In statistics, stochastic processes are the main tool for modelling spatial and temporal data, and the most commonly used type are the Gaussian processes. A popular approach to define Gaussian processes is through linear stochastic differential equations driven by white noise. This methodology is often denoted the SPDE approach. By utilising methods from numerical analysis one has been able solve several of the computational bottlenecks that have hampered the usage of Gaussian processes for real world data sets, in particular for spatial statistics. I will focus on how one can apply the same methodology to create non-Gaussian processes, in space and time. I will also discuss what practical properties these processes have over their Gaussian counterpart. Further, I will present very recent work where we have extended the SPDE approach for Gaussian process, to Euclidean graphs (like street networks). Here the linear differential operators are obtained using Quantum graphs, which opens these methods for a new wide range of applications.

Predicting the emergent properties of a material from a microscopic description is a scientific challenge. Machine learning and reverse-engineering have opened new paradigms in the understanding and design of materials. However, the soft-matter field has lagged far behind in embracing this approach for materials design. The main difficulty stems from the importance of entropy, the ubiquity of multi-scale and many-body interactions, and the prevalence of non-equilibrium and active matter systems. The abundance of exotic soft-matter phases with (partial) orientation and positional order like liquid crystals, quasicrystals, plastic crystals, along with the omnipresent thermal noise, makes the classification of these states of matter using ML tools highly non-trivial. In this talk, I will address questions like: Can we use machine learning to autonomously identify local structures, detect phase transitions, classify phases and find the corresponding order parameters in soft-matter systems, can we identify the kinetic pathways for phase transformations, and can we use machine learning to coarse-grain our models? Finally, I will show how one can use machine learning to reverse-engineer the particle interactions to stabilize nature’s impossible phase of matter, namely quasicrystals?

Deep learning-based approaches have revolutionized virtually all domains of computer vision, including the field of microscopy image analysis. In image reconstruction and classification, in segmentation and artificial labelling, they have pushed both flagship projects and bread-and-butter everyday tasks, allowing image analysis to keep pace with the recent advancements in imaging technology and instrumentation. I will talk about the recent work of my group that has enabled the first segmentation of cells in a whole animal imaged with electron microscopy, our collaboration with microscope developers for trusted reconstruction of light field microscopy and our current efforts to reduce the annotation budget for training of segmentation algorithms. I will also show how we strive to make our methods accessible to biologists without computational expertise through our software ilastik and through the emerging community network collection at the BioImage Model Zoo.

Vielfalt und Pluralität sind mittlerweile Alltag in unserer Gesellschaft, im Privat- und Berufsleben: Menschen mit unterschiedlichsten Lebensentwürfen, Hintergründen, Glauben oder Herkunft treffen aufeinander.

In dem zweiteiligen Workshop werden wir uns mit verschiedenen theoretischen Ansätzen im Themenfeld Diskriminierung beschäftigen und anhand praktischer Übungen einen eigenen erfahrungsbasierten Zugang dazu finden. Ziel ist es, Selbstverständlichkeiten und gängige Narrative diskriminierungskritisch zu hinterfragen sowie Handlungsoptionen aufzuzeigen, die tradierte Verhaltensmuster aufbrechen können. Ein besonderes Augenmerk soll dabei auf die Geschlechtergleichberechtigung gelegt werden.

Dozentinnen:
Halszka ?liwa-Ohnesorge verantwortet die Bildungsstelle Plurales Heidelberg bei Mosaik Deutschland e.V. Sie studierte Religionswissenschaft und Politikwissenschaft Südasiens an der Universität Heidelberg. Nachdem Studium arbeitete sie u.a. für ein ziviles, indisch-pakistanisches Friedensprojekt, bei dem die gleichberechtigte Förderung von Jungen und Mädchen ein zentrales Element war. Heute liegt der Schwerpunkt ihrer Arbeit auf der vorurteilsbewussten und diskriminierungskritischen politischen Bildung.

Lara Track leitet das Antidiskriminierungsbüro Heidelberg (ADB) bei Mosaik Deutschland e. V. Sie berät Menschen, die Diskriminierung erfahren haben und setzt sich in Netzwerken auf kommunaler, Landes- und Bundesebene gegen Diskriminierung ein. Im Rahmen ihrer wissenschaftlichen Mitarbeit am Historischen Seminar der Universität Heidelberg erforscht sie Verbindungen zwischen Frauenfriedensaktivismus und Feminismus in den USA. In der Auseinandersetzung mit US-Feminismen gründet ihr Interesse am Konzept der Intersektionalität, das in der mehrdimensionalen Beratung im ADB zum Tragen kommt.

Multiscale Methods
[]
Seminar
Speaker: Prof. Robert Scheichl & Linus Seelinger • IWR
Location: TBD.
Link:
ECTS: 6

Topic:
Natural or engineered materials often contain two or more key constituents, arranged in a heterogeneous structure varying at different scales. Such materials are desirable because their macroscopic properties can be superior to the properties of the individual constituents. It is even possible to explicitly design them for a particular purpose by changing the composition of the constituents.

An example are carbon fibre composites for lightweight structures and vehicles. The mathematical modelling of such heterogeneous or composite materials typically leads to PDEs with highly oscillating coefficients. Direct numerical solution of such problems with traditional methods, such as finite elements is computationally expensive. Just to compute the correct qualitative behaviour, the mesh resolution would need to be sufficiently high to capture all the fine scale variation.

In this seminar, we will study multiscale numerical methods that address various aspects of this challenge. This includes the generation of low-dimensional yet high-quality approximation spaces, acceleration of fine-scale solutions and efficient uncertainty quantification for multiscale problems.

Each student will present a key publication on multiscale numerical methods with an aim to cover most aspects of the field.

Prerequisites:
Basic knowledge of partial differential equations, Sobolev spaces and Finite Element methods is required. For the uncertainty quantification topics, basics of probability theory are needed.

Have you sat in front of an empty sheet of paper or an empty file before, trying to start a report, a paper or your PhD Thesis, but struggling to make progress? Or have you had to read a research article relevant to your PhD project that was so incomprehensible or dry that you were wishing to be somewhere else for the day to end? Good scientific writing is an absolutely essential part of our work as researchers; only through good communication will we be able to captivate the audience and truly enthuse them for our achievements and results. It is as important as pure academic ability for a successful professional career in academia, but also in industry, but typically we are not trained formally in good writing in a mathematics or science degree. In this crash course I aim to give you some useful pointers on good writing in the mathematical sciences, and through some hands-on exercises we will try to immediately put them in practice.

Working as a PhD student you have the challenging task of developing research findings and write you doctoral thesis within three years. This alone is a demanding job. In addition, it is vital to the scientific process that your findings are presented to the scientific community. For most PhD students this is the first big project in their professional life and it could have a crucial impact on their future professional career. PhD students are highly motivated when they start their PhD studies but may underestimate the need for professional management for this three-year project "doctoral thesis".

This seminar demonstrates how to approach the doctoral thesis in a professional way. Project management tools and techniques are used, tailored to the specific situation of PhD students. You will learn how to set a project vision, define clear objectives, gain buy-in from your supervisor and other colleagues in your group, and how to develop a project plan, which is structured and at the same time flexible enough to easily adjust to unexpected findings. You will establish a "controlling cycle" which helps you to recognise risks and problems as early as possible, and you will learn how to manage critical situations and deal with ups and downs. Furthermore, networking with colleagues, supervisors and other people are important topics of this seminar.

Throughout the seminar, you will work on your own doctoral thesis and share your experience with others. This seminar is most beneficial for PhD students who are in the early phases of their doctoral thesis. At the end of the seminar you will have established a strategy on how to approach your own doctoral thesis. During the follow-up REVIEW we will share experience and best practices and deal with open questions from the first module.

This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time.
You will also learn and practise the basic concepts of project management – a prerequisite in industries and research institutions.

Uncertainty quantification plays an important role in many engineering applications. In this talk we discuss some recent advancements in the approximation of high-dimensional functions appearing in this context. We provide new results for surrogate modeling and parameter estimation in cases where the uncertainty is described by a Gaussian random field. Additionally we address how the usage of neural networks to learn linear and nonlinear operators may help in solving such tasks, and what possible challenges might lie ahead.

The IWR Colloquium will be held as an in-person event at the Mathematikon. In addition it will be streamed via Zoom.

We all have different networks - no matter whether we call them "network" or not. These networks provide support, advice and help in different fields. To better use and understand them it is crucial to be aware of the fact that the purpose influences the network itself. If our purpose (or aim or goal) remains unclear efficient networking is impossible. The workshop "Purposeful Networking" provides basic information on networking and gives space to clarify personal aims - to create a link between network and purpose.

Spatial and temporal control of molecular phenomena is crucial to develop intelligent materials for applications ranging from sensing over catalysis to photonic computing. In this regard, stimuli-responsive molecules enable to influence structural and dynamic properties at the atomic level in a highly controlled manner by external stimuli such as light.

To transfer external inputs into functionality, a detailed understanding of both, the operation mechanism of the responsive species and their impact on the environment, is needed. In the presentation, I will give an overview of our activities on developing and applying theoretical methods to investigate the dynamics of stimuli-responsive systems at different time and length scales. By establishing an automated and first-principle based parametrization approach for interatomic potentials, investigations of equilibrium and out-of-equilibrium phenomena in responsive and functional materials are performed.

My presentation is divided in three parts, which cover our atomistic investigations on (i) responsive molecular species (e.g. molecular switches/machines), (ii) the dynamic intermolecular interplay during molecular aggregation and atomically precise restructuring and (iii) hierarchal and responsive architectures (e.g. phase change material and functionalized Metal-Organic Frameworks). By directly linking of our multi-scale simulations with experimental techniques, our work contributions to a rational development of responsive and functional materials.

Romberg Inaugural Lecture: Model Order Reduction Methods for Time-Harmonic Wave Problems
[]
IWR Colloquium
Speaker: Prof. Francesca Bonizzoni, Romberg Visiting Scholar
Location: Virtual Talk
Link:
ECTS: not yet determined

Many engineering applications require the numerical evaluation of time-harmonic wave propagation problems over a range of frequencies. The most used technique to discretize partial differential equations is the finite element method. Due to the oscillations of analytical solutions the finite element discretization often becomes computationally expensive.

Model order reduction methods provide reliable approximations of the solution at low computational cost. In particular, they allow very fast responses both for real-time and multi-query contexts.

This talk deals with novel model order reduction techniques tailored to time-harmonic wave problems relying only on a precomputed set of snapshots, they present great flexibility, since they allow the construction of a surrogate starting from snapshots obtained via black-box solvers (e.g., commercial software).

The method’s efficiency is investigated in several examples, including transmission-reflection and scattering problems. Especially in the context of optimal control problems, where standard numerical techniques are unfeasible, the employment of surrogate models is crucial.

Deep learning is fueling advances and breakthroughs in a dizzying array of data-intensive scientific fields. In this talk, I will highlight recent and ongoing work of our lab that leverages deep learning to push the limits of advanced microscopy.
A long-standing challenge in the life sciences is to visualize biological cells at high resolution and with high throughput. Single molecule localization microscopy (SMLM) is among the most powerful and widely used super-resolution imaging methods, but is typically very slow and low throughput. I will present ANNA-PALM, a computational technique based on deep learning that can reconstruct high resolution views from strongly under-sampled SMLM data and widefield images, enabling considerable speed-ups without any compromise on spatial resolution. I will also highlight Shareloc, an online platform to facilitate the sharing and reanalysis of SMLM data, and Imjoy, a computational platform dedicated to facilitating the uptake of state-of-the art deep learning methods in the biomedical research community.

Die Aufnahme, Speicherung und Weitergabe großer Mengen von Daten ist eine Aufgabe, der sich menschliche Gesellschaften bereits seit Jahrtausenden zu stellen haben. Einen der größten Meilensteine bildet dabei die Erfindung der Schrift, zuerst nachweisbar im Mesopotamien des 4. vorchristlichen Jahrtausends. Zeugnisse dieses Quantensprungs finden sich unter anderem in der Heidelberger Uruk-Warka-Sammlung, die spektakuläre Funde aus dem Sitz des mythischen Königs Gilgamesch bewahrt. Diese Objekte zeugen jedoch nicht nur von den Leistungen antiker Archivare, sie stellen auch eine Herausforderung für ihre modernen Nachfolger dar. Mit welchen Methoden lassen sich archäologische Daten heute sammeln, bewahren und austauschen?

Antworten darauf liefert das Heidelberger "Forensic Computational Geometry Labratory" (FCGL), an dem Methoden zur Digitalisierung archäologischer Artefakte entwickelt werden. Mittels eines Laserscanners werden die Objekte aufgenommen und über das Programm Gigamesh in digitale 3D-Modelle umgesetzt. Unter anderem kommt dieses Verfahren im Projekt "Scanning for Syria" zum Einsatz, in dessen Zentrum die Sicherung von durch den syrischen Bürgerkrieg bedrohten Kulturgütern steht. Das HAIlight im März bietet Ihnen die Gelegenheit, den Forschern am FCGL bei ihrer Arbeit mit Objekten der Uruk-Warka-Sammlung über die Schulter zu schauen.

Das HAIlight findet am Freitag, den 27.03.2020 um 18:00 Uhr statt und dauert ca. eineinhalb bis zwei Stunden. Die Plätze für die Teilnahme sind begrenzt und werden nach Ablauf der Rückmeldefrist verlost. Details zu Treffpunkt und Veranstaltungsort erhalten Sie in der Teilnahmebestätigung.

Für die Platzvergabe schicken Sie uns bitte bis spätestens Montag, 16.03.2020 unter Angabe Ihres Namens eine E-Mail an hailight@alumni.uni-heidelberg.de. Begleitpersonen können dann teilnehmen, wenn nach Berücksichtigung aller interessierten HAI-Mitglieder noch freie Plätze zur Verfügung stehen.

Talk - "Mathematics of Life" Special Interest Group

Climate change, increasing human mobility and trade, pathogen evolution and resistance, urbanization, and ecological range shifts - all these global factors destabilize the current pattern of infectious diseases, notably those transmitted by vectors. There is general agreement that this will lead to the emergence and re-emergence of a wide range of infectious diseases. In Europe, water and vector-borne diseases such as Vibriosis, Dengue, Chikungunya, West Nile Virus, Lyme disease and Tick-borne encephalitis are proliferating and emerging among previously immunologically naive populations. This may result in severe disease outbreaks, morbidity, mortality, long-term disability and increasing burdens of disease. In Low-and-Middle-Income Countries (LMICs), Ebola has not yet been contained, malaria, Dengue and cholera are still associated with massive disease burdens, and arboviruses are likewise on the rise. Globally, resistance to antibiotics and insecticides is a growing concern. New genotypes and new pathogens are threatening to unleash pandemics with potential to have major societal impact, if not effectively monitored and controlled. The recent Corona virus situation is a good example of how sensitive the global population is to local emergence of viruses with epidemic potential. Achieving the sustainable development goals 2030 requires new methods for monitoring, surveillance and analysis, all of which are key for the deployment of more efficient, timely and strategic prevention.

To address these unprecedented global challenges, the public health professions are called on to develop new approaches and innovative techniques and solutions. We are now entering a world, where increasing availability of high quality, high-dimensional data and advanced computation techniques allow for previously unimaginable levels of precision and granularity with respect to monitoring and forecasting of disease outbreaks, their associated burdens and intervention demands. Digitalization, machine learning and artificial intelligence are still in its infancy in terms of public health applications, but hold great promise for revolutionizing public health decision-making, and for sustaining and safeguarding the global population.

This talk provides a few examples on how data from many different disciplines and domains, including climate, human mobility and social media, can be integrated in machine learning, and help timely risk assessment, better forecasts and support the development of more effective prevention strategies. In the talk I will discuss the methods, findings and give examples of tangible decision tools in the making in collaboration with public health policy makers.

ECTS: 2

In times of global pressure on universities the principle of academic freedom is fiercely debated within and outside academia. But surprisingly few academics and even less students have fundamental knowledge what academic freedom is – and what it is not. Debates and actions are often driven by emotions and subjective feelings about a ”proper university“ instead of well founded information.

In this course, participants will

I. discuss the principle of academic freedom – its history, its juridical status and its formal applicability

II. learn to discern academic freedom and other civil liberties (e.g. open speech, freedom of opinion)

III. understand the complexity of taking action in the face of violations to academic freedom

IV. sharpen our awareness for threats to academic freedom in our own societies.

The course material is in English and discussions will be a mixture of English and German (summaries in English will be possible). We expect engagement and interest – no marks will be given!


The course will be held in consecutive blocks. *Friday sessions* are compulsory (course of one hour/1 stündig), Saturday sessions are optional (course of two hours/2-stündig).

he course will take place in the conference room of Marsilius-Kollleg, Im Neuenheimer Feld 130.1

IWR Colloquium & HGS MathComp Von Neumann Lecture

A traditional goal of algorithmic optimality, squeezing out flops, has been superseded because of evolution in architecture. Flops no longer serve as a reasonable proxy for all aspects of complexity. Instead, algorithms must now squeeze memory, data transfers, and synchronizations, while extra flops on locally cached data represent only small costs in time and energy. Hierarchically low-rank matrices realize a rarely achieved combination of optimal storage complexity and high-computational intensity in approximating a wide class of formally dense linear operators that arise in applications for which exascale computers are being constructed. They may be regarded as algebraic generalizations of the fast multipole method. Methods based on these hierarchical data structures and their simpler cousins, tile low-rank matrices, are well proportioned for early exascale computer architectures, which are provisioned for high processing power relative to memory capacity and memory bandwidth. Hierarchically low-rank matrices are ushering in a renaissance of computational linear algebra. A challenge is that emerging hardware architecture possesses hierarchies of its own that do not generally align with those of a given algorithm-application pair. We describe modules of a software toolkit, hierarchical computations on manycore architectures (HiCMA), that illustrate these features and are intended as building blocks of applications, such as matrix-free higher-order methods in optimization and large-scale spatial statistics. Some modules of this open-source project have been adopted in the software libraries of major vendors.

Many of the most relevant observables of matter depend explicitly on atomistic and electronic details, rendering a first principles approach to computational materials design mandatory. Alas, even when using high-performance computers, brute force high-throughput screening of material candidates is beyond any capacity for all but the simplest systems and properties due to the combinatorial nature of chemical compound space, i.e. all the compositional, constitutional, and conformational isomers. Consequently, efficient exploration algorithms exploit implicit redundancies and correlations. I will discuss recently developed statistical learning based approaches for interpolating quantum mechanical observables throughout chemical compound space. Numerical results indicate remarkable performance in terms of efficiency, accuracy, scalability and transferability.

ECTS: not yet determined

The Prelude: Pioneering the Development of Conservation Technology in Cambodia

The Sequel: Pioneering the Use of Digital Technology in Banteay Chhmar with the IWR, Heidelberg University

John Sanday who is a Conservation Architect, has spent the last 45 years working in Asia. For at least 15 of these years he has worked in Cambodia. Arriving for the first time in Siem Reap in 1989, John and his team pioneered one of the first projects in Angkor - the Preah Khan Conservation Training Project which was supported by the World Monuments Fund. John’s early memories were of the Khmer Rouge skirmishes which were still taking place on the outskirts of the historic city of Angkor – it was a memorable start to several decades of work in one of the greatest monumental cities of its time, which was placed on the UNESCO World Heritage List in 1992.

In the first part of his talk, John will describe his early days of setting up the first major conservation-training programme in the 12th Century Buddhist monastic complex of Preah Khan. He will talk about some of the problems they had to face and the techniques developed in Preah Khan and three other sites in Angkor. There will be illustrations showing Angkor as John found it in the 1990’s and it will set the background for him to side track to another major Khmer site in the far North of Cambodia.

John will dedicate the second half of his talk to one of the lesser known but highly significant Khmer sites known as Banteay Chhmar, which is closely linked to Angkor. This 12th Century Buddhist, monastic complex stylistically emulates the temples in Angkor and belongs to the Bayon period. Banteay Chhmar became John´s link with IWR and its team. John and Hans Georg Bock had been fantasizing for many years on trying to link heritage conservation with applied mathematics. Here in Banteay Chhmar, they initiated an extraordinary project and a way of using ‘state of the art’ technology to digitally reconstruct iconic face tower as well as sections of the enclosure wall with its exquisite bas-relief carvings. Precise dimensions of hundreds of stone blocks were recorded digitally to recreate the tower, which had to be dismantled and rebuilt, as well as the fallen stones of the bas relief as the first step to their reconstruction.

Khmer architect Dr. Pheakdey Nguonphan (Royal University of Phnom Penh) and Dr. Anja Schäfer (IWR) developed the digital technology and formed a multi-disciplinary research team including stone masons from Preah Khan. John will describe the system, that was developed to solve “John’s Puzzle” and illustrate how the stones began to recognize their original positions in the structures, without having to move the stones manually.

There will be time for questions and discussion at the end.

Industry’s demand for using big data analysis tools is growing evermore. Public clouds developed in recent years have provided various data analysis tools for analysts, data scientists, researchers, and academics without the burden of permanently allocating and continuously maintaining high performance computing facilities. Google Cloud Platform (GCP) is one of the public cloud providers with a variety of state-of-the-art products addressing wide range of challenges in data engineering and data analytics.
The internet age and growth of social networks was a game changer for human sciences. If previously researchers and analysts had to carefully design data collection processes, now people are sharing their thoughts and concerns on a daily (or hourly) basis. In this workshop we are going to introduce GCP pipelines from streaming Twitter API’s data into a data warehouse. Afterwards, we will perform sentiment analysis and network analysis to find the patterns in user’s behavior. Finally, using visualization tools in python, we will prepare effective communication of the results.

Mathematical modelling of epigenetic regulation and its effects on cell differentiation and reprogramming?
[]
Talk
Speaker: Prof. Tomás Alarcón
Location: Mathematikon, Im Neuenheimer Feld 205, 69120 Heidelberg
ECTS: not yet determined

The inherent capacity of somatic cells to switch their phenotypic status in response to damage stimuli in vivo might have a pivotal role in ageing and cancer. However, how the entry-exit mechanisms of phenotype reprogramming are established remains poorly understood. In an attempt to elucidate such mechanisms, we herein introduce a stochastic model of combined epigenetic regulation (ER)-gene regulatory network (GRN) to study the plastic phenotypic behaviours driven by ER heterogeneity. To deal with such complex system, we additionally formulate a multiscale asymptotic method for stochastic model reduction, from which we derive an efficient hybrid simulation scheme. Our analysis of the coupled system reveals a regime of tristability in which pluripotent stem-like and differentiated steady-states coexist with a third indecisive state, with ER driving transitions between these states. Crucially, ER heterogeneity of differentiation genes is for the most part responsible for conferring abnormal robustness to pluripotent stem-like states. We formulate epigenetic heterogeneity-based strategies capable of unlocking and facilitating the transit from differentiation-refractory (stem-like) to differentiation-primed epistates. The application of the hybrid numerical method validates the likelihood of such switching involving solely kinetic changes in epigenetic factors. Our results suggest that epigenetic heterogeneity regulates the mechanisms and kinetics of phenotypic robustness of cell fate reprogramming. The occurrence of tunable switches capable of modifying the nature of cell fate reprogramming might pave the way for new therapeutic strategies to regulate reparative reprogramming in ageing and cancer

Agile management approaches for research groups
[]
Workshop
Speaker: Manuela Schmidt
Location: Mathematikon, Conference Room, 5th Floor, Room 5/104, Im Neuenheimer Feld 205, 69120 Heidelberg
ECTS: 1

Scrum is an agile framework within which people can address complex adaptive problems, while productively and creatively delivering products. Kanban uses a visual system for managing work as it moves through a process, allowing team members to see the state of every piece of work at any time.

Both of them are agile approaches to project management. Agile project management is one answer to the growing speed in which projects need to be delivered and the realization that many projects are not delivered as originally planned. This is especially true for projects with volatile or unclear requirements at project start.

Concepts like continuous improvement, fast feedback cycles, limiting work in progress and transparency can bring value to teams as well as to individuals.

During this workshop you will learn:

- What is Agile? Get an overview of agile principles, values, techniques and methods
- How to use Kanban for your personal use? Boost your productivity and get things done!
- How can Kanban be introduced to a team? Streamline work between team members and create transparency on status
- How can Scrum be adapted in an academic environment? Use a process framework to improve collaboration and knowledge-sharing between lab members and cut down your fixed meeting times

Program:

9:00-12:00

- Agile introduction - origins, mindset & term definition
- Introduction to Scrum Framework
- Introduction to Kanban
- Applying theory into practice (Part 1)
- Personal Kanban - how to gain focus and transparency in your daily work

ECTS: not yet determined

In the year 2000, the Clay Mathematics Institute selected seven of the most important open problems in modern mathematics and offered a prize of $1 million for a solution to any of them. Nineteen years on, only one millennium prize problem has been solved. In this talk, Prof. David Silvester will discuss the Navier-Stokes existence and smoothness problem, one of the six remaining unsolved problems.

The Navier-Stokes equations are central to fluid dynamics and its applications to engineering and physics, describing viscous turbulent flow, e.g. of air around an aeroplane wing, weather patterns and blood flow through arteries. Despite the wide-ranging applicability of the Navier-Stokes equations, it is still not known whether they always admit smooth solutions, which contain no unphysical "blow-ups", or singularities.

AnyDSL: A Partial Evaluation Framework for Programming High-Performance Libraries
[]
Talk
Speaker: Sebastian Hack
Location: Seminar Room A, Mathematikon
ECTS: 0

riting performance-critical software productively is still a
challenging task because performance usually conflicts genericity.
Genericity makes programmers productive as it allows them to separate
their software into components that can be exchanged and reused
independently from each other. To achieve performance however, it is
mandatory to instantiate the code with algorithmic variants and
parameters that stem from the application domain, and tailor the code
towards the target architecture. This requires pervasive changes to
the code that destroy genericity.

In this talk, I advocate programming high-performance code using
partial evaluation and present AnyDSL, a clean-slate programming
system with a simple, annotation-based, online partial evaluator. I
will show that AnyDSL can be used to productively implement
high-performance codes from various different domains in a generic way
map them to different target architectures (CPUs with SIMD units,
GPUs). Thereby, the code generated using AnyDSL achieves a performance
that is in the range of multi man-year, industry-grade,
manually-optimized expert codes and highy-optimized code generated
from domains specific languages.

[]
Workshop
Speaker: Various Speakers
Location: Institute for Theoretical Studies Heidelberg
Link:
ECTS: not yet determined

This workshop aims at discussing and devising new and unifying concepts to calculate and understand molecular stresses in complex materials. Such molecular stresses can stem from quantum chemical calculations, atomistic or coarse-grained Molecular Dynamics simulations. They could be inherent to the system, i.e. reflect intrinsic tension or pre-stress, or build up upon applying external mechanical perturbations.

In an informal workshop we will bring together experts from the relevant scientific areas, computational physics, materials science, and biological matter, and will leave room for a few contributed talks from participants as well as many discussions among speakers and participants. There is the possibility to participate in a small practical workshop on force distribution analysis (FDA).

Bayes-Optimal Filtering in the Tensor Train Format

Speaker: Prof. Colin Fox, Romberg Visiting Scholar

ECTS: not yet determined

Optimal sequential Bayesian inference, or filtering, for the state of a dynamical system requires solving a partial differential equation. For low-dimensional, smooth systems the finite-volume method is an effective solver that gives estimates that converge to the optimal continuous-time values. We develop this finite-volume filter, and give numerical examples that show that the filter we develop is able to handle multi-modal filtering distributions. For higher-dimensional systems the curse or dimensionality may be overcome by representing density functions by an interpolated tensor train decomposition. We give examples of filtering for continuous-time and discrete-time systems.

ECTS: 2

Computational modeling has become more and more important in the life sciences. One important class of models are compartment models and ordinary differential equations are widely used to describe the time evolution of the model components in a deterministic way. This compact course will introduce stochastic compartmental modeling. The objectives of the course are to learn a) methods that allow to simulate stochastic models and b) which effects so called intrinsic stochasticity can have on systems dynamics. These effects will make it evident that specific calibration techniques are needed in order to be able to cope with stochastic effects and exploit their information. The course will c) give a flavor of how calibration can be performed. Time will also be devoted to let the participants learn d) when stochastic modeling is necessary and beneficial.
This course will consist of lectures as well as practical exercises. Therefore, participants are encouraged to bring laptops (please contact me in case laptop sharing is desired). There is no prior software or programming experience necessary.

Workshop

ECTS: not yet determined

Scientific computing concerns the development of mathematical models and high-performance software able to describe, simulate and learn the behaviour of complex phenomena. Applications can arise from any area of applied sciences (e.g. engineering, physics, biology, chemistry) and typically retain the challenging task of quantifying high-dimensional uncertainty due to known unknowns and unknown unknowns present in the natural system. When this is added to the computational burden of approximating and solving complex mathematical models, the application of standard inference algorithms, e.g. for parameter estimation, prediction or optimization, becomes quickly unfeasible within a reasonable computational budget.

The aim of the workshop is to bring together researchers working in Uncertainty Quantification, Machine Learning and Bayesian Statistics with a particular focus on high- and infinite-dimensional problems from scientific computing, where the sparsity or uncertainty of data requires an integration of inference and learning algorithms with established physical models, such as partial differential equations. Advances in this complex field of research require a concerted effort from many disciplines, which we hope to foster at the workshop.

This workshop is part of the Thematic Semester Uncertainty Quantification, Machine Learning & Bayesian Statistics in Scientific Computing at MAThematics Center Heidelberg (MATCH) in conjunction with the Excellence Cluster STRUCTURES. The financial support from MATCH and from the Heidelberg Graduate School of Mathematical and Computational Methods for the Sciences (HGS MathComp) is gratefully acknowledged.

"Guided Parameter Exploration in Interactive Visualization"
Prof. Stefan Bruckner, University of Bergen, Norway

Over the past decades the field of visualization has firmly established itself as an important and constantly expanding discipline within computer science. Computer-based visualization seeks to provide interactive graphical data representations, taking advantage of the extraordinary capability of the human brain to process visual information. Advanced visualization methods now play an important role in the exploration, analysis, and presentation of data in many fields such as medicine, biology, geology, or engineering. This development, however, has also lead to the fact that there is now a vast number of often very specialized techniques to visualize different types of data tailored towards specific tasks. Hence, particularly for non-experts, it becomes increasingly difficult to choose appropriate methods that will provide the optimal answers to their questions.

In this talk, I will discuss previous and ongoing research on how we can explore and navigate the space of visualizations itself. By consider the interplay between data, visualization algorithms, their parameters, perception, and cognition as a complex phenomenon that deserves study in its own right, we are making progress in providing goal-oriented interfaces for visual analysis. For instance, we can make the modification of input parameters of visualization algorithms more intuitive by normalizing their perceived effects over the entire value range, and provide visual guidance about their influence. Furthermore, by incorporating additional knowledge into the visualization process, we can infer information about the goals of a user, and develop smarter systems that automatically suggest appropriate visualization techniques. This line of investigation leads us along the path towards a new type of visual data science, where automated data analysis approaches such as deep learning are tightly coupled with interactive visualization techniques to exploit their complementary advantages for knowledge discovery in data-driven science.

This talk focuses on four active branches in scientific visualization research: topological analysis, feature extraction, volume rendering, and solver visualization. We examine various roles of topological analysis in flow fields and beyond, we investigate feature extraction in higher dimensions and higher order, we extend volume rendering beyond direct geometrical optics, and we extend scientific visualization from the traditional analysis of simulated data to analysis of the numerical solvers that produce the data. On the application side, we discuss the utility of the investigated visualization techniques in the natural and life sciences, and indicate possible directions of future research.

"Insights from the Pixel Dump: Scientific Image Visualization"
Prof. Thomas Schulz, Universität Bonn

Big, complex, and dynamic image data play an increasing role in science and medicine. This poses important and interesting challenges to scientific visualization, since the traditional visual inspection of raw images is no longer a suitable strategy for their effective and efficient interpretation. Instead, mathematical modeling, feature extraction, and machine learning are required to pre-process the data, and to allow the human user to reason about it at a higher level of abstraction. This talk will illustrate these points with several specific examples from diffusion Magnetic Resonance Imaging, as well as image data from ophthalmic epidemiology.

PIMS-Germany Workshop on Discretization of Variational Eigenvalue Problems
[]
Workshop
Speaker: Various Speakers
Location: Mathematikon, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

Recent years have seen intense development of discretization schemes for incompressible flow problems in two directions. On the one hand, pairs of discrete spaces with a commuting diagram property for the divergence operator have been developed, with the result that it is now possible to compute actually divergence free solutions with reasonable effort. In particular for high Reynolds number flow, this property is important, since the control of the divergence by the gradient is too weak. Alternatively, penalization of the divergence has been investigated thoroughly with the same goal of achieving better solutions for high Reynolds numbers. On the other hand, replacements for the pressure Poisson problem have been developed, allowing for much faster projection of approximate solutions into the divergence free subspace, in particular with high performance computing in mind. The study of stability of such flows and of critical modes requires the solution of nonsymmetric variational eigenvalue problems. Critical modes are characterized by eigenvalues with small real part, which again may suffer from spurious divergence. In order to approximate such eigenvalues, many flow problems must be solved iteratively, which brings fast solvers back into the game.

The goal of this workshop is convening top researchers in the fields of flow and eigenvalue problems in order to understand the interplay of the interacting components better and to profit from recent research of groups with different focus. Furthermore, its aim is intensifying cooperation between the members of PIMS and universities in Germany with a clear focus on common interest.

PIMS - Germany Workshop on Modeling and Analysis of PDEs for Biological Applications

Workshop
Speaker: Various Speakers

Link:
ECTS: not yet determined

This mini-workshop will bring together experts in modeling and analysis of organizing principles of multiscale biological systems such as cell assemblies, tissues and populations, and collective dynamics of cells. We will focus on questions arising in systems biology and medicine which are related to emergence, function and control of spatial structures, cell-cell interactions, and inter-individual heterogeneity in biological dynamics. Mechanisms of symmetry breaking and establishment of spatial patterns in gene expression leading to different differentiation programmes are central issues of developmental biology, while the understanding of their perturbation and deregulation leading to abnormal development is important in cancer research. Evolution of large scale spatial patches such as, for example, systems of vegetation patterns observed in drylands, is essential for ecosystems. Dynamics of appearance and disappearance of such patterns have a direct economic impact. Spatio-temporal dynamics arising through a diffusion field is also a central theme in characterizing the collective response of microbial particles.

Pattern formation is also an important topic in materials science. For example, the nature of formation and evolution of nano-scale structures in energy conversion devices such as fuel cells and solar cells is decisive for the quality of the performance of these devices. Though some of these patterns are well characterized, there are other that we are only beginning to understand. Mathematical modeling is a powerful technique to address key questions and paradigms in diverse model systems and to provide quantitative insights into the role of the nonlinear and nonlocal interactions within the systems and with the external fields as well as of the growth and transport processes and their impact on the observed patterns.
Although applied to specific biological, ecological, chemical, medical or physical systems, mathematical models allow for a comparative analysis of design principles in diverse systems. The focus of this proposed conference is to present and analyze models of partial and integro-differential equations applied to problems of spatio-temporal patterning. The goal of the meeting is to bring together specialists in Germany and from PIMS universities working on different aspects of the field, including mathematical modeling and applications, analysis of the underlying equations as well as numerical simulation, in order to exchange ideas, present new techniques, and identify challenging new research directions of common interest. The focus will be in identifying and understanding of mechanisms of pattern formation including formation of travelling waves, stationary and dynamical patterns, the effect of mechanical-chemical forces on patterns, stability and bifurcation theory, mechanisms underlying collective dynamics in cell signalling, and the emergence of singularities. Applications to developmental biology, ecology, cell-signalling, and materials science will be presented and discussed.

The outcome of the workshop will be two-fold. Firstly, various mathematical methods and techniques presented for diverse types of model PDE sytems in biology, will lead to cross-fertilization and will help solving in tackling problems related to different applications. Secondly, this workshop will identify common research interests and establish new research collaborations on specific projects among researchers at PIMS and at Universities in Heidelberg, Munster and Berlin.

ECTS: not yet determined

Learning time-series models is useful for many applications, such as simulation and forecasting. In this study, we consider the problem of actively learning time-series models while taking given safety constraints into account. For time-series modeling we employ a Gaussian process with a nonlinear exogenous input structure. The proposed approach generates data appropriate for time series model learning, i.e. input and output trajectories, by dynamically exploring the input space. The approach parameterizes the input trajectory as consecutive trajectory sections, which are determined stepwise given safety requirements and past observations. We analyze the proposed algorithm and evaluate it empirically on a technical application. The results show the effectiveness of our approach in a realistic technical use case.


Afterwards there will be a Meet & Greet with Pizza and Beer (and non-alcoholic beverages)!

A Sequential Homotopy Method for Mathematical Programming Problems

Link:
ECTS: 0

We consider nonconvex and highly nonlinear mathematical programming problems including finite dimensional nonlinear programming problems as well as optimization problems with partial differential equations and control constraints. We present a novel numerical solution method, which is based on a projected gradient/anti-gradient flow for an augmented Lagrangian on the primal/dual variables. We show that under reasonable assumptions, the nonsmooth flow equations possess uniquely determined global solutions, whose limit points (provided that they exist) are critical, i.e., they satisfy a first-order necessary optimality condition. Under additional mild conditions, a critical point cannot be asymptotically stable if it has an emanating feasible curve along which the objective function decreases. This implies that small perturbations will make the flow escape critical points that are maxima or saddle points. If we apply a projected backward Euler method to the flow, we obtain a semismooth algebraic equation, whose solution can be traced for growing step sizes, e.g., by a continuation method with a local (inexact) semismooth Newton method as a corrector, until a singularity is encountered and the homotopy cannot be extended further. Moreover, the projected backward Euler equations admit an interpretation as necessary optimality conditions of a proximal-type regularization of the original problem. The prox-problems have favorable properties, which guarantee that the prox-problems have uniquely determined primal/dual solutions if the Euler step size is sufficiently small and the augmented Lagrangian parameter is sufficiently large. The prox-problems morph into the original problem when taking the step size to infinity, which allows the following active-set-type sequential homotopy method: From the current iterate, compute a projected backward Euler step by applying either local (inexact) semismooth Newton iterations on the step equations or local (inexact) SQP-type (sequential quadratic programming) methods on the prox-problems. If the homotopy cannot be continued much further, take the current result as a starting point for the next projected backward Euler step. If we can drive the step size all the way to infinity, we can transition to fast local convergence. We can interpret this sequential homotopy method as extensions to several well-known but seemingly unrelated optimization methods: A general globalization method for local inexact semismooth Newton methods and local inexact SQP-type methods, a proximal point algorithm for problems with explicit constraints, and an implicit version of the Arrow--Hurwicz gradient method for convex problems dating back to the 1950s extended to nonconvex problems. We close the talk with numerical results for a class of highly nonlinear and badly conditioned control constrained elliptic optimal control problems with a semismooth Newton approach for the regularized subproblems.

Efficiency of Home Radon Mitigation Systems in some Canadian Provinces

ECTS: not yet determined

Lung cancer (LC) is the leading cause of death of cancer in Canada in both men and women, and indoor radon is the second leading cause of LC after tobacco smoking. The Population Attributable Risk (PAR) is used to assess radon exposure risk. We use the PAR to identify the radon levels responsible for most LC cases. During the period 2006–2009, 6% of houses in Ontario, 9% of houses in Alberta, 19% of houses in Manitoba, 7% of houses in Quebec, and 5% of houses in British Columbia had radon levels higher than 200 Bq/m3 and was responsible about 913, 211, 260, 972, and 258 lives, respectively. Radon mitigation programs could have prevented these LC cases. We use the PAR function of the two variables, radon action, and target levels, to search for a possible optimal mitigation program. The PAR is a linear function in the target radon value with an estimated slope of 0.0001 for Ontario, Alberta, Quebec, and British Columbia, and 0.0004 for Manitoba. The PAR is an increasing function in the radon action level. The PAR is sensitive to changes in the radon mitigation program and as such, any improvement is a worthwhile investment.

Location: Mathematikon, Conference Room / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: 0

Tidy data is a standard way of storing your data where columns are variables and rows are observations. Tidy data, particularly when coupled with tidy tools, makes data analysis easier because you can spend less time wrangling the output of one function so that it works as the input for another. Tidy data will make your analysis easier but how you get wild-caught data into a tidy form? In this talk, I`ll discuss some of the tools that I have worked on for tidying data (e.g. the tidyr package), the limitations of those tools, and what I`m thinking about next. In particular, I`ll discuss a new approach for "pivoting" data, and discuss some of the challenges posed by data stored in hierarchical form (e.g. JSON).

Exhibition Opening "Women of Mathematics throughout Europe"
[]
Public Talk
Location: Mathematikon, Foyer, Im Neuenheimer Feld 205, 69120 Heidelberg
ECTS: not yet determined

The event is organized in close cooperation with the conference "Geometric Analysis meets Geometric Topology“.

Description:

This touring exhibition, whose starting point is the 7th ECM held in July 2016 in Berlin, stems from the observation that nowadays, women still find it difficult to embrace a career in the mathematical academic world and the disparity between the proportion of men and that of women among professional mathematicians is still shamefully large.

The thirteen women mathematicians portrayed here share with us their experience, thus serving as role models to stimulate young women scientists to trust their own strength. In presenting mathematics through women mathematicians’ perspectives and samples of their life stories, we hope to highlight the human aspects of producing mathematics, making this discipline more tangible and therefore more accessible to outsiders or newcomers.

This exhibition and the catalogue (publishing house: Verlag am Fluss) are the result of the joint efforts of the photographer Noel Tovia Matoff and four mathematicians by Sylvie Paycha, Sara Azzali, Alexandra Antoniouk, Magdalena Georgescu, with the precious help of Maria Hoffmann-Dartevelle, who translated into German and Sara Munday, who proofread the interviews and, last but not least, our two inspired graphic designers Wenke Neunast/eckedesign (exhibition) and Gesine Krüger (catalogue).

The event is kindly supported by the Heidelberg Laureate Forum Foundation (HLFF).

Project Management Tailored for Doctoral Thesis
[]
Key Competences
Speaker: Dr. Justus Meier
Location: Mathematikon, INF 205, 5th floor, SR 10
ECTS: 2

Working as a PhD student you have the challenging task of developing research findings and write you doctoral thesis within three years. This alone is a demanding job. In addition, it is vital to the scientific process that your findings are presented to the scientific community. For most PhD students this is the first big project in their professional life and it could have a crucial impact on their future professional career. PhD students are highly motivated when they start their PhD studies but may underestimate the need for professional management for this three-year project "doctoral thesis".
This seminar demonstrates how to approach the doctoral thesis in a professional way. Project management tools and techniques are used, tailored to the specific situation of PhD students. You will learn how to set a project vision, define clear objectives, gain buy-in from your supervisor and other colleagues in your group, and how to develop a project plan, which is structured and at the same time flexible enough to easily adjust to unexpected findings. You will establish a "controlling cycle" which helps you to recognise risks and problems as early as possible, and you will learn how to manage critical situations and deal with ups and downs. Furthermore, networking with colleagues, supervisors and other people are important topics of this seminar.
Throughout the seminar, you will work on your own doctoral thesis and share your experience with others. This seminar is most beneficial for PhD students who are in the early phases of their doctoral thesis. At the end of the seminar you will have established a strategy on how to approach your own doctoral thesis. During the follow-up REVIEW we will share experience and best practices and deal with open questions from the first module.
This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time.
You will also learn and practise the basic concepts of project management – a prerequisite in industries and research institutions.

Moderne Materialien zählen zu den zentralen Zukunftsthemen in der angewandten Forschung. Die Verwendung hochmoderner Planungsprozesse in den Materialwissenschaften und bahnbrechende Entdeckungen in der Nanoforschung, in der organischen Elektronik und in der computergestützten theoretischen Chemie haben zu einer Revolution geführt. Als eine der Schlüsseltechnologien für das 21. Jahrhundert erlauben die Modernen Materialien einen zielgerichteten Einsatz in zahlreichen Anwendungsgebieten. Durch die Kombination von mehreren Eigenschaften werden immer effektivere Werkstoffe ermöglicht. So können zum Beispiel Stoffe entwickelt werden, die gleichzeitig extrem leicht aber dennoch stabil sind oder wesentlich effizienteren Energietransport erlauben.

Was ist von der Materialforschung in der nächsten Dekade an Entwicklungen noch zu erwarten? Wie wirken hier die unterschiedlichen Forschungsrichtungen zusammen? Und welche Rolle spielt die computergestützte Simulationstechnik bei diesem Paradigmenwechsel von der experimentellen Entwicklung neuer Materialien zur gezielten Planung von Materialeigenschaften am Computer? Mit diesen Fragen beschäftigt sich der 16. Modellierungstag. Wir haben Experten aus Universitäten, Forschung und Produktion eingeladen, um in Impulsvorträgen und praxisnahen Diskussionen die zentralen Fragestellungen aus diesem interdisziplinären Feld zu erörtern.

Die Veranstaltung wird von HGS MathComp und der Stadt Heidelberg organisiert sowie von der IHK Rhein-Neckar und der Industrie unterstützt.

Pioneering Structural Repair & Conservation in Angkor
[]
Talk
Speaker: John Sanday OBE, FSA
Location: Centre for Organismal Studies Heidelberg (COS), Seminar Room 00.005, INF 230, 69120 Heidelberg
ECTS: 0

John Sanday, Conservation Architect, who has spent the last 45 years working in Asia, worked for at least 20 of those years in Cambodia. Arriving for the first time in Siem Reap in 1989, he and his team pioneered the first project, the Preah Khan Conservation Training Project which was supported by the World Monuments Fund. The Khmer Rouge disturbances were still evident in Angkor as the fast-growing sub-tropical jungle, which engulfed the partially ruined monuments provided an ideal hiding place for the Khmer Rouge militia. John’s early memories were of the skirmishes still taking place on the outskirts of the historic city of Angkor and the sounds of explosions and gunfire – it was indeed a memorable start to several decades of working in one of the largest monumental cities of its time, which was later to be placed on the UNESCO World Heritage List.
John will briefly describe his early days of setting up the first major conservation training programme in the 12th Century Buddhist monastic complex. As many of you will be able to recall the time we have spent together in Angkor, I will take this opportunity to describe some of the problems we had to face and the techniques we developed in Preah Khan and three other sites in Angkor to conserve the structures with minimal intervention. There will be plenty of illustrations showing Angkor as John found it in the 1990’s and it will provide an excuse and set the background for him to side track to another Khmer style site in the far North of Cambodia.
Banteay Chhmar, one of the great Khmer sites, is closely linked to Angkor despite it being about 100km to its north. This 12th Century site, which is stylistically emulates the temples in Angkor of the Bayon period, is my link with IWR as it was the birth of an extraordinary project which Professor Georg Bock and had been fantasizing for many years trying to link heritage conservation with applied mathematics. We found a way of using ‘start of the art’ technology to digitally reconstruct a section of exquisite bas relief carvings on a stone enclosure wall which enclosed the temple complex known as Banteay Chhmar. This project need careful measurement and digital recreation of the fallen sections as the first step to their reconstruction following a highly sensitive conservation intervention to protect the decorative stone carvings. The Bas Relief Wall measures 1,400 metres in length of which 75% has collapsed.

Similarly, a free-standing sandstone tower supporting four carved images of, possibly the king or maybe the Buddha, measuring approximately 15 metres high, was threatening imminent collapse. These two different architectural elements were selected to test a system for digital re-assembly.

A section of the enclosure wall was selected. Each stone in was measured and referenced. Missing stones were located and the decorative stones were carefully dismantled and each stone was scanned. A process was also developed for the consolidation and cleaning of these masterpieces ready for reconstruction.
Drawings of the Tower were prepared referenced and carefully dismantled and each stone was scanned.
John will describe the system which IWR developed to solve “John’s Puzzle”, Khmer architect Dr. Peakdey Nguonphan and Dr. Ann from Germany headed up the team which developed the digital technology.
As a result of this multi-disciplinary research and along with support from many of the IWR teaching staff, the stones began to recognize their original positions in the structures and along with the knowledge and experience of the Khmer stone masons who had worked with us in Preah Khan, progress was made. I will explain the full process with illustrations.

Time will be allocated for questions ad discussions.

LES/Flamelet Modeling of Multi-regime Turbulent Jet Flames
[]
Talk
Speaker: Dr. Yong Hu
Location: INF 205, SR 2
ECTS: 0

Turbulent flames feature a complex multi-scale turbulence and chemistry interaction, which usually leads to the flame structure that cannot be simply categorized into the single-regime burning. The simplest burning structure of flame is in either non-premixed or premixed regime, for which two distinct modes are observed for the species transportation and reactions. However, the combustion processes are further complicated in most practical applications, for example, the liquid-fueled burner that characterizes the additional dispersed phase for fuel supply, and hence the partially premixed reaction as well as an evaporation-dominated regime. This multi-regime combustion mode is therefore more often involved and poses a challenge to the model. In this work, due to the computational efficiency, the conventional flamelet model that is originally proposed for simple premixed or non-premixed reactions is explored for use in large eddy simulation (LES) of multi-regime turbulent flames. The changes of reaction regime at sub-grid scale are dynamically described by a flame index that is developed in a way facilitating the implementation of single-regime flamelet structures. The validity of models is examined by consideration of both gas and liquid flames, which include a lifted jet flame and a piloted spray flame. Results show that although formed by different mechanism, the partially premixed reaction is predominant in the considered flames, and the present model can properly reproduce these structures. Computed data are in general good agreement with experimental profiles of temperature, species mass fraction and droplet size.

ECTS: 2

Projekte im Bildungs-, Sozial- und im Forschungsbereich dienen dazu, kurz- oder mittelfristig arbeitsplatzsichernd zu wirken und Nachwuchskräften weitere Berufserfahrung und Qualifizierungsmöglichkeiten zu bieten. Aus der Perspektive von wissenschaftlichen Einrichtungen und Hochschulen sind sie zudem erwünscht, um die Drittmittelbilanz zu stärken und somit im nationalen Leistungsvergleich der Hochschulen eine mo?glichst positive Stellung zu erreichen.

Häufig müssen Mitarbeiter/innen von Hochschulen oder Forschungsinstituten ohne entsprechende Vorerfahrung an Projektanträgen arbeiten. Möglichkeiten der hausinternen Unterstützung oder des Austausches mit projekterfahrenen Mitarbeitern/innen sind selten. Dadurch gehen wertvolle Zeit- und Personalressourcen verloren. Dieses Seminar hat deshalb zum Ziel, die Antragstellung stärker zu professionalisieren, Tipps und Tricks zu vermitteln und im Endeffekt eine höhere Erfolgsbilanz zu erzielen.

Im Seminar gehe ich mit Ihnen Schritt für Schritt die wesentlichen Aspekte der Antragsgestaltung durch und erkläre diese an Beispielen. Dabei werden auch einige Grundlagen des Projektmanagements vermittelt. Denn Fehler, die bei der Planung gemacht werden, können später zu schwerwiegenden Folgen im Verlauf des Projektes führen.
In diesem Seminar werden Problemstellungen aufgegriffen wie:
• Wie entwickle ich aus meiner Idee ein perfektes Konzept?
• Antragssprache – Antragsprosa: Einige Schreibtipps
• Wie interpretiere und verstehe ich ein Förderprogramm? Was muss ich beim Antragschreiben unbedingt berücksichtigen?
• Über den Umgang mit Gutachtern: Evaluationsprozesse, Wie wird ein Antrag gelesen? Welche Faktoren führen zu Entscheidungen?
• Wo und wie finde ich Partner und wie binde ich diese in ein Konsortium ein?
• Wie recherchiere ich nach Förderprogrammen?
• Wie passe ich meine Idee an die Vorstellungen des Förderers an?
Da jedes Programm andere Fo?rderbedingungen stellt, werde ich mich auf einige fachspezifisch passende Pro- gramme konzentrieren. Grundbedingungen und Vorgehensweise in der Antragsgestaltung sind jedoch auf alle Förderprogramme übertragbar.
Alle Projektphasen oder wichtige Themen werden in Arbeitsgruppen vertieft. Einige TeilnehmerInnen werden im Seminar Gelegenheit haben, aktiv in Arbeitsgruppen an eigenen Projektantra?gen zu arbeiten und diese mit ent- sprechendem Feedback von mir sowie den anderen TeilnehmerInnen zu einem Grobkonzept zu entwickeln. Nutzen Sie diese Chance! Bringen Sie nach Möglichkeit eine Projektidee mit, die Sie gerne zu einem Antrag ent- wickeln würden. Ich werde vorbereitend vor dem Seminar noch einen Fragebogen versenden um evtl. passende Förderprogramme recherchieren zu können.

Mit der Verfügbarkeit leistungsfähiger Computer und Softwarewerkzeuge hat sich die mathematische Modellierung, Simulation und Optimierung (MSO), als zentrale Methodik des Wissenschaftlichen Rechnens, zu einer Schlüsseltechnologie entwickelt. Aktuelle Ergebnisse der MSO in der Hochschulforschung führen allerdings auf Grund befristeter Projekte oft nur zu prototypischer, nicht nachhaltiger Software. Dieses strukturelle Hindernis führt dazu, dass neue Verfahren ihr großes Potential zur Lösung der immer komplexeren Probleme in Wissenschaft, Industrie und Gesellschaft nur begrenzt entfalten. Mit der Einrichtung des durch die Carl-Zeiss-Stiftung geförderten SCSC sollen am IWR Strukturen geschaffen werden, die dieses Hindernis beseitigen und einen wirksamen Technologietransfer in inner- und außeruniversitäre Anwendungsbereiche ermöglichen.

Representation of soil water movement
[]
Talk
Speaker: Dr. Hannes Bauser
Location: Mathematikon, INF 205, Common Room
ECTS: 0

Soil water movement is a key process in ecosystem services, such as biomass production, fresh water retention, climate regulation, or water buffering and filtering. However, the quantitative description of soil water movement on all relevant scales from meters to the global scale, remains an open challenge. In this talk I focus on the meter scale, where soil water movement can still be described with the process based Richards equation. Nevertheless, the mathematical representation of soil water movement exhibits uncertainties in all model components. This means that the representation of uncertainties in each model component becomes an integral part of the model formulation. The goal is then an optimal consistent representation with minimal uncertainties. Data assimilation methods, which combine models and data, are a key tool for this task. In this talk I present an application on a real-world case. We assessed the key uncertainties for the specific hydraulic situation of a 1-D soil profile with TDR (time domain reflectometry)-measured water contents. We employed a data assimilation method, the ensemble Kalman filter (EnKF), with an augmented state to represent and reduce all key uncertainties (initial condition, soil hydraulic parameters, small-scale heterogeneity, and upper boundary condition), except for an intermittent violation of the local equilibrium assumption by the Richards equation. To bridge this time, we employed a closed-eye period, which pauses the parameter estimation and only guides the states through this time. This ensured constant parameters throughout the whole estimation, suggesting that we achieved a more consistent description and limited the incorporation of errors into parameters.

There are various reasons for studying fixed-point property of non-continuous mappings, e.g., due to errors or perturbations, original mappings lose their contractivity or their continuity, and therefore, the existence of their fixed-points is no more warranted. To counteract this problem, we present some theorems on approximate fixed-points of roughly contractive mappings and roughly continuous mappings along with illustrating examples.

Polynomial Acceleration of MCMC

ECTS: not yet determined

Standard Markov chain Monte Carlo (MCMC) algorithms perform a stationary linear iteration on the space of probability distributions, and hence converge geometrically. Stationary linear solvers were state-of-the-art in the 1950’s, but are now considered very slow precisely because they are geometrically convergent. We show that the same polynomial acceleration methods that have been developed for linear iterative solvers may also be applied to accelerating MCMC, in certain settings.

Low-Rank Tensor Decompositions for High-Dimensional Uncertainty Quantification
[]
Talk
Speaker: Dr. Sergey Dolgov
Location: Mathematikon, Seminar Room A, Ground Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

Uncertainty quantification and inverse problems in many variables are pressingly needed tasks, yet high-dimensional functions are notoriously difficult to integrate in order to compute desired quantities of interest. Functional approximations, in particular the low-rank separation of variables into tensor product decompositions, have become popular for reducing the computational cost of high-dimensional integration down to linear scaling in the number of variables. However, tensor approximations may be inefficient for non-smooth functions. Sampling based Monte Carlo methods are more general, but they may exhibit a very slow convergence, overlooking a hidden structure of the function. In this talk we review tensor product approximations for the problem of uncertainty quantification and Bayesian inference. This allows efficient integration of smooth PDE solutions and quantities of interest. Moreover, we can use the low-rank approximation to construct efficient proposal density in the MCMC algorithm for inverse problems. This combined MCMC method is more accurate also if the quantity of interest is not smooth, such as the indicator function of an event.

New Energy Space Modeling and Implications on Complexity of Decision Making and Control in Electric Energy Systems

Speaker: Prof. Marija Ilic, Senior Research Scientist
Location: Mathematikon, Conference Room (5/104), 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

In this talk we present a recently-introduced multi-layered modeling framework for posing the problem of safe, robust and efficient design and control for rapidly changing electric energy systems. The proposed framework establishes dynamic relations between physical concepts such as stored energy, useful work, and wasted energy, on one hand; and modeling, simulation, and control of interactive modular complex dynamical systems, on the other. In particular, our recently introduced energy state-space modeling approach for electric energy systems is further interpreted using fundamental laws of physics in multi-physical systems, which are modeled as dynamically interacting modules.

This approach is shown to be particularly well-suited for scalable optimization of large-scale complex systems. Instead of having to use simpler models, the proposed multi-layered modeling of system dynamics in energy space offers a promising basic method for modeling and controlling inter-dependencies across multi-physics subsystems for both ensuring feasible and near-optimal operation. It is illustrated how this approach can be used for understanding fundamental physical causes of inefficiencies created either at the component level or resulting from poor matching of their interactions.

This talk is based on the recent paper by M. D. Ilic and R. Jaddivada entitled "Multi-layered interactive energy space modeling for near-optimal electrification of terrestrial, shipboard and aircraft systems”, Annual Reviews in Control, available online May 2018. The paper provides theoretical foundations for Dynamic Monitoring and Decision Systems (DyMonDS) framework envisioned as the next-generation SCADA.

The control design based on joint work with Xia Miao and R. Jaddivada for microgrids and integration of renewable resources and demand response is used as an example to illustrate potential benefits of this approach.

Finally, many open modeling, estimation and optimization challenges/opportunities using this modeling approach are discussed.

Fine-scale structure of the airflow above ocean surface waves

Talk
Speaker: Marc Buckley
Location: Institut für Umweltphysik, INF 229, Seminarraum 108/110
ECTS: not yet determined

?The transfers of momentum and scalars across the air-sea interface are influenced by small-scale turbulent processes. In spite of extensive existing work on the topic, our understanding of near-surface physics remains incomplete. The measurement of the small-scale dynamics very close to the rapidly moving ocean surface can be challenging! We present laboratory and field measurements of the submillimeter-scale motions in the airflow above waves. A high resolution, large field of view Particle Image Velocimetry (PIV) system was specially developed for the measurements, capable of capturing 2D velocity fields in the turbulent airflow directly above the wavy surface. The system was recently deployed on RP FLIP. Using preliminary field measurements as well as laboratory wave tank measurements, we will discuss the impact of waves on the structure of the wind stress within the wave boundary layer, and in particular how breaking and non-breaking waves influence the momentum flux_s partitioning between viscous, form drag, wave-coherent and turbulent contributions.

Spray Combustion: From a Flamelet Model to a Flamelet Theory
[]
Talk
Speaker: Prof. Hernán Olguín
Location: Mathematikon, Im Neuenheimer Feld 205, SR 10
ECTS: not yet determined

The task of formally extending the gas flamelet theory to spray flames has been only partially fulfilled and, whereas several spray flamelet models have been derived during the last decades, only few works regarding the spray flamelet equations (SFE) are available in the literature. Therefore, a degree of maturity similar to the one already achieved for gas flames has not yet been reached for spray flames. Among the remaining open issues is the closure of the SFE in mixture fraction space, which includes developing models for the Scalar Dissipation Rate (SDR) and for the different evaporation related sources appearing due to the consideration of a liquid phase.


In this presentation, recent advances in the closure of the SDR are described, which include a reformulation of the spray flamelet equations in terms of the gradient of mixture fraction instead of the SDR itself and the derivation of a transport equation for this new variable. The results are expected to help advancing towards the development of a self-contained spray flamelet theory.

Menschen machen Modelle interessant! Die immense Vielfalt von menschlichen Attributen, Verhaltensweisen oder Reaktionen sorgt aber auch dafür, dass die Modellbildung ungleich komplexer wird. Um beispielsweise einen Prozess im sozialen oder ökonomischen Leben realitätsnah abzubilden sollte ein möglichst exaktes Bild eines Menschen entworfen werden. Die Abwägung zwischen der Einfachheit eines Modells einerseits und seiner Aussagekraft andererseits stellt dabei eine der größten Herausforderungen dar. Wie gehen Modellierer sicher, dass die gewählten Ansätze nicht nur die jeweilige Forschungsfrage beantworten sondern auch allgemeine Gültigkeit besitzen?

Der Modellierungstag greift die spannende Frage nach der Bildung von „menschlichen Modellen“ auf und fördert den Austausch zwischen Forschern, Entwicklern und Anwendern. Beiträge aus unterschiedlichen Fachrichtungen liefern dazu Denkanstöße und Diskussionsgrundlagen.

ECTS: not yet determined

This presentation will examine the possibilities of interdisciplinary historical interpretation of artwork based on the analysis of remnant artifacts of past civilizations. How can digital technology offer solutions to assess and analyse artifacts, sculptures and architecture that have been damaged through the vicissitudes of time? Digital technology also can enhance the accessibility and display of these objects and curatorial research in museums.

Dr. Marnie Feneley will present her research, past and present, which aims to reassess the out-dated Art Historical Analytical System. She will speak about new paradigms which seek to revise traditional methodologies of art historical analysis by using empirical methodology (for example, to analyse a large data set of Asian sculpture). In particular, the use of photogrammetric modeling and high-resolution immersive visualisation systems to address the traditional perceived (visual and verbal descriptive) analysis of art history along the Mercantile Maritime Route from India to China. The objective is to gain a deeper understanding of sculptural tradition, styles, religious affiliations and cultural transmissions in Asia from the 2nd - 14th century CE.

Dr. Marnie Feneley is a lecturer in Asian Studies at the University of NSW. As a post doctoral fellow, she has been researching the transmission of Buddhism from India to Southeast Asia for the "Atlas of Maritime Buddhism,” a world touring exhibition based on the compelling story of the spread of Buddhism through the seaports of Eurasia, supported by the latest archaeological evidence.
Marnie has spent over a decade researching Southeast Asian sculpture and religion. Her doctoral thesis from the University of Sydney, “The West Mebon Vi??u: style, hydraulics and political power,” will be published later this year through National University of Singapore press. Her thesis examined the famous bronze sculpture of Vi??u found in a water shrine in the middle of the West Baray at Angkor in 1936. She has amalgamated archaeological and art historical research with digital technology by reconstructing this fractured sculpture and its temple in a digital reconstruction. She is considered a pioneer in the field digital archaeology and heritage. She regularly gives invited talks at national and international forums.

[]
Talk
Speaker: Dr. Anna Trykozko
Location: Mathematikon, Conference Room (5/104), 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
ECTS: not yet determined

Studying effective properties of porous media based on simulating flows at pore scale has become a widely applied procedure during last years. Realistic structures of pores are commonly obtained by X-ray computed micro-tomography (micro-CT). In this work we consider weakly permeable samples in which a significant fraction of porosity could not be detected at a micro-CT resolution. We therefore apply an approach in which parts of samples characterized as _solids_ during micro-CT imaging are treated as permeable porous media represented with an assumed (small) permeability. Reliable estimations of permeability of ‘solid’ parts were obtained by incorporating Scanning Electron Microscopy data. This way our computational hybrid approach combines two microimaging methods of different resolutions.

ECTS: 1

Voice matters!
Speech- & Vocaltraining
How do people learn? There_s the internet, there are books, of course. But most of the information we draw on, has originally been transmitted by the human voice: We learn while we listen to others. For teaching - and for many other activities - the way people talk is therefore essential for success.
One_s own voice is the most personal way of expressing oneself, too - and much more than just a "carrier of information" while lecturing, delivering a speech or in discussions. The human voice is in fact "the social medium no. 1". To bring the message across should therefore also take the speech qualities and one_s relation to the audience into account. If one_s voice is too low, raspy or breathy - or if one just talks too fast, people will not listen - even though the content is meaningful and important.
In this workshop, participants will explore their own voice qualities and speaking potentials in order to facilitate understanding - and to bring their messages across in a more convincing way. The methods and exercises - carefully chosen for the specific conditions of scientific life - include rhetorical, linguistic and communicational elements, with video-recording and professional feedback.

Link:
ECTS: not yet determined

The European Finite Element Fair (EFEF) is an annual series of completely informal small workshops throughout Europe with equal initial conditions for each speaker. EFEF provides a platform for high-level discussions on current research on finite element approximation, in the broadest sense, of partial differential equations. Authors are encouraged to present one new idea rather than review a full research project. In this spirit, the communication of recent and new results, even not yet published, is very welcome. A few, but strict, rules apply to EFEF in order to distinguish it from existing workshops and minisymposia in the field.

Format of the Meeting:

- Speakers at EFEF are volunteers from the audience. Provided that they are present throughout the meeting, all participants are invited to talk. Potential participants are strongly encouraged to attend at least one meeting before volunteering to speak.

- Based on the number of speakers the time available will be divided into slots for the talks. The order of the speakers will be determined through random choice, by drawing names out of a hat. Speakers cannot request a specific time to talk.

- The Presentations. Bring your presentation as a pdf-file on a USB-stick. That will make life/technical support much more relaxed and easier during the conference.

- Each speaker should introduce himself or herself, the title and topic, and is expected to leave sufficient time, within the allocated time-slot, for discussion. Speakers have to prepare a talk that can be trimmed to various lengths (from seconds to 20 minutes). For a smooth meeting, the time table will be strictly enforced.

- The Book. Since EFEF 2005, a book has been available (in the Oberwolfach tradition) to record new analytical and numerical results presented during EFEF. Results can be hand-written or typeset and glued into the book.

Efficient stage-parallel time integration and tensor-product solvers for discontinuous Galerkin methods
[]
Talk
Speaker: Will Pazner
Location: Mathematikon, Seminar Room A , Ground Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

Implicit time integration for discontinuous Galerkin (DG) discretizations is important in the context of boundary layer flows, anisotropic, unstructured meshes, and high degree polynomial approximations. Effective preconditioning strategies are essential to the efficient iterative solution of the resulting large, sparse linear systems. In this talk, I will discuss two topics: (1) fully implicit Runge-Kutta solvers, and (2) tensor-product preconditioners for very high polynomial degrees.

(1) There are several advantages to using fully-coupled implicit Runge-Kutta schemes compared with traditional DIRK or BDF methods. However, such methods couple all of the Runge-Kutta stages, resulting in a much larger system of equations. We transform the resulting system of equations to maximize sparsity, and then develop several ILU-based preconditioners with favorable performance properties. These solvers have the additional advantage that they allow for parallelism across the stages.

(2) Furthermore, the DG method allows for arbitrary order of accuracy, according to the degree of polynomial approximation used. High-degree polynomials result in extremely restrictive CFL conditions, motivating the use of implicit solvers. We develop efficient solvers and preconditioners that exploit the natural tensor-product structure of quadrilateral and hexahedral grids in order to obtain methods with optimal computational complexity.

Mathematical modeling and numerical simulations can provide an invaluable tool for the interpretation and analysis of the circulatory system functionality, in both pathological and healthy situations. However, although many substantial achievements have been made, most of the difficulties are still on the ground and represent major challenges for the coming years.

In this talk we introduce some mathematical models of the cardiovascular system and comment on their significance to yield realistic and accurate numerical results. They include fluid-structure interaction (FSI) models to account for blood flow in compliant vessels, analysis of absorbing boundary conditions to deal with the numerical spurious reflections due to the truncation of the computational domain and the geometrical multiscale approach to simulate the reciprocal interactions between local and systemic hemodynamics. Results on the simulation of some image-based patient-specific clinical applications will also be presented.

Mathematische Modelle kommen in unserem Alltag in vielfältigen Varianten vor. Dabei spielt die Lokalisierung eine besonders wichtige Rolle: Ein abstraktes Modell wird konkretisiert, indem es mit lokalen Daten angereichert und so präzise für einen Kunden angepasst wird.

Die geografische Komponente ist vor allem in der modellgestützten Optimierung eine entscheidende Größe. Ein Beispiel mag dies verdeutlichen: Während die Fahrroutenoptimierung in nicht-geobasierten Modellen auf abstrakte Grundgrößen wie durchschnittliche Fahrtzeit von Ort zu Ort zurückgreifen muss, können in Modellen mit detaillierten geografischen Daten exakte Vorhersagen für die Fahrtdauer beim Einsatz unterschiedlicher Fahrzeuge der zur Verfügung stehenden Flotte errechnet und in die Planoptimierung eingespeist werden. Die Kopplung mit aktuellen Verkehrsdaten erlaubt sogar eine tagesabhängige Nachoptimierung und so eine noch bessere Anpassung der Fahrpläne an die realen Gegebenheiten.

Diese Verbesserungen können auch in vielen anderen Bereichen erreicht werden:

- Modellierung der Ausbreitung von Infektionserkrankungen in Abhängigkeit von regionalem Klima und Wetter
- Hochwasservorhersage auf Basis detaillierter Geländekarten
- Planung von Funknetzwerken unter Berücksichtigung von Bebauungsplänen

Der Zusammenhang zu geografischen Daten ist so offensichtlich, dass die Anbindung geografischer Informationssysteme oft selbstverständlich erscheint. Auf dem Modellierungstag wollen wir uns mit dieser Facette der Modellbildung beschäftigen und auf Schwierigkeiten bei der Modellerstellung, Risiken in der Datengenerierung und Chancen im wirtschaftlichen Einsatz eingehen. Experten aus Wissenschaft, Forschung und Praxis geben dazu Einblicke in aktuelle Projekte und neue Entwicklungen.

Difference Operators in Sobolev Spaces and Applications
[]
Talk
Speaker: Prof. Alexander L. Skubachevskii
Location: Mathematikon, Seminar Room 12 / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
ECTS: not yet determined

The theory of elliptic differential-difference equations has many interest-ing applications e.g. to
• the theory of sandwich shells and plates,
• the Kato problem concerning the analyticity of the square root of an analytic function of dissipative operators,
• nonlocal boundary value problems arising in plasma theory,
• the theory of multidimensional diffusion processes,
• nonlinear optics, …

This theory is based on the properties of difference operators acting in Sobolev spaces. Most important property of a regular difference operator:

It maps the Sobolev space of the first order with the homogeneous Dirichlet boundary condition onto the subspace of the Sobolev space of the first order with nonlocal boundary conditions continuously and bijectively. This result allows to reduce boundary value problems for strongly elliptic differential-difference equations to elliptic equations with nonlocal boundary conditions. Conversely, in some cases nonlocal elliptic boundary value problems can be reduced to elliptic differential-difference equations.

This talk will present a unifying theme among the various effects of protein charges and polar groups. Simple models will be used to illustrate basic ideas about electrostatic interactions in proteins, and these ideas in turn will be used to elucidate the roles of electrostatic interactions in protein structure, folding, binding, condensation, and related biological functions. In particular, I will examine how charged side chains are spatially distributed in various types of proteins and how electrostatic interactions affect thermodynamic and kinetic properties of proteins. Both important historical developments and recent experimental and theoretical advances in quantifying electrostatic contributions of proteins will be highlighted.

Mathematical modelling and simulation of physiological processes in organs and organisms are confronted with the challenge that the processes take place in complex structures, often on branching networks. In this lecture we consider networks arising in plants (“trees”, root-systems, vessel systems in leaves) and in vascular systems - in particular in cardio vascular systems. We are going to focus on the following topics:

1. characterization of the arising complex networks and construction of a coding system, including the essential information required in real applications;
2. requirements for the data, methods for data collection and processing;
3. algorithms to solve the geometric inverse problem to determine from CT-data the geometry and the developed code of the underlying network;
4. presentation and discussion of results obtained in recent research at IWR for the blood vessel system for the human heart, based on real CT-data;
5. open problems, requirements from the applications.

Stabilised Finite Element Methods for Variational Inequalities

Speaker: Prof. Rolf Stenberg
Location: Mathematikon, Conference Room / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: 0

We survey our recent and ongoing work [1,2] on finite element methods for contact problems. Our approach is to first write the problem in mixed form, in which the contact pressure act as a Lagrange multiplier. In order to avoid the problems related to a direct mixed finite element discretisation, we use a stabilised formulation, in which appropriately weighted residual terms are added to the discrete variational forms. We prove that the formulation is uniformly stable, which implies an optimal a priori error estimate. Using the stability of the continuous problem, we also prove a posteriori estimates, the optimality of which is ensured by local lower bounds. In the implementation of the methods, the discrete Lagrange multiplier is locally eliminated, leading to a Nitsche-type method [3].

For the problems of a membrane and plate subject to solid obstacles, we present numerical results.

Joint work with Tom Gustafsson (Aalto) and Juha Videman (Lisbon).

Location: Mathematikon, Conference Room / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

The splitting of poyharmonic equations into lower-order equations is subtle as the obvious splitting requires smoothness of the solution that might not be guaranteed by the elliptic regularity of the underlying PDE. This talk introduces a new splitting based on a Helmholtz-type decomposition. This splitting does only require the natural Sobolev regularity that is given by the weak formulation. The new mixed formulation allows for standard Lagrange ansatz functions of arbitrary polynomial degree. This talk will also state a posteriori error estimates and will illustrate the new method in numerical experiments. Applications include, e.g., the biharmonic problem from plate theory.

Wo gibt es Mathematik zu entdecken? Wie kann der aktive und neugierige mathematische Blick von Lernenden gestärkt und erweitert werden? Dialogisches und forschendes Lernen sind zwei Ansätze für den Mathematikunterricht, die den individuellen Fragen, Ansätzen und Erarbeitungswegen der Lernenden Raum geben. Gleichzeitig gelingt es, ausgehend von alltäglichen, ja oft sogar eher banal erscheinenden Fragestellungen tiefergehend mathematisch zu arbeiten. Sehr häufig kommt man dabei sogar auf aktuelle mathematische Forschungsfragen. Nicht einfach ist die Frage, wie forschendes Lernen im Fach Mathematik überhaupt authentisch gestaltet werden kann. Es wird über aktuelle Forschung sowie über Erfahrungen aus der Lehramtsausbildung und der wissenschaftlichen Begleitung des Programms „Mathe.Forscher“ der Stiftung Rechnen berichtet. Der Vortrag bietet konkrete Unterrichtsideen und Anregungen für den Unterricht in den Sekundarstufen.

A plasma target for high neutralization of powerful beams of negative ions is considered. The plasma is held in a magnetic trap with multipole magnetic walls. The inverse of the magnetic tube was proposed to limit the expiration of the plasma through the inlet and outlet ports in the target. Mathematical modeling of plasma dynamics in the trap was performed by the PIC method. The basic idea of the PIC method and new analytical tests for numerical models and codes are presented. Plasma distribution in the trap the efficiency estimate of particle confinement in the magnetic field were obtained. Simulation results were compared with experimental data.

The global flow picture for the steady Boltzmann equation is studied (jointly with Shih-Hsien Yu). The time-asymptotic analysis is based on explicit construction of the Green's function. For the resonance situation when one of the Euler characteristic speeds is near zero, there are coupling of Knudsen-type and fluid-like waves. The construction of Bifurcation and Sone Manifolds yields finite dimensional reduction of the center manifold. Fluid nonlinearity is recognized and applied to study the global flow picture.

Motion of mobile robotic systems can be based on specific motions of auxiliary internal masses inside the main body of the robot. Such robots have no outward devices, can be hermetic and operate in various environment, including tubes, vulnerable or hazardous media. Control of rigid bodies by means of internal mobile masses can be useful also for spacecraft. Control of one-dimensional and two-dimensional motions of bodies with internal masses is discussed. Optimal controls for such systems are obtained.

Who I am:
My name is Jonathan Griffiths (Jonnie). I have extensive experience in both freelance academic English-language proofreading and in tutoring of various kinds (workshops, classes, one-on-one tuition). I am simultaneously writing a PhD in Ancient Philosophy at UCL, UK.

Suggested Content and Breakdown of Workshop:
I am altogether flexible and happy to tailor an academic English-language workshop to the specific needs and requests of those in attendance. However, from my experience of the workshop environment in the past, I have often found it helpful to isolate certain core features of successful & stylish English writing technique. The below headings are only a handful of examples:

- Argumentation: use of connectives of different kinds (e.g. to contrast or rebut an argument previously made, to advance a complementary argument, to cross-reference and connect parts of your argument and written work together)
- Introductions & Conclusions
- Scholarly etiquette: acknowledging previous opinion, arguing against it in a professional manner; or creating an academic space for your own original contribution (e.g. to a scholarly field)
- Footing: shorthand and cross-reference (including correct use of Latin and/or abbreviated terms: see, cf. pp., ff., etc.)
- Writing Abstracts (or other materials that preface your main paper): tips & tricks to synthesise your argument into a digestible package (e.g. of 250 words or shorter).

Uncertainty quantification (UQ) is a fast growing research area which deals with the impact of parameter, data and model uncertainties in complex systems. We focus on models which are based on partial differential equations (PDEs) with random inputs. For deterministic PDEs there are many classical analytical results and numerical tools available. The treatment of PDEs with random inputs, however, requires novel ideas and tools. We illustrate the mathematical and algorithmic challenges of UQ for Bayesian inverse problems arising from geotechnical engineering and medicine, and an optimal control problem with uncertain PDE constraints.

Fixation Probabilities under Demographic Fluctuations
[]
Talk
Speaker: Dr. Peter Czuppon
Location: Bioquant, SR 043, INF 267, 69120 Heidelberg
Link:
ECTS: 0

We consider a population consisting of two species. Each type gives birth and dies independently of the other one. Population size is regulated by intra- and interspecific competition events letting the model follow generalized Lotka-Volterra dynamics. A quantity of interest in finite populations is the probability of fixation/extinction of one type. While it has been studied broadly in the context of fixed or deterministically varying population sizes we approximate the fixation probability in populations with stochastically fluctuating sizes. In order to do so we will take the limit of weak selection, i.e. the "fitness" benefit of one type over the other is very small.

This talk is organized by “Mathematics of Life” - a special interest group of doctoral students of the HGS MathComp.

Project Management Tailored for Doctoral Thesis
[]
Key Competences
Speaker: Dr. Justus Meier
Location: Mathematikon, INF 205, 5th floor, SR 11
ECTS: 2

Working as a PhD student you have the challenging task of developing research findings and write you doctoral thesis within three years. This alone is a demanding job. In addition, it is vital to the scientific process that your findings are presented to the scientific community. For most PhD students this is the first big project in their professional life and it could have a crucial impact on their future professional career. PhD students are highly motivated when they start their PhD studies but may underestimate the need for professional management for this three-year project "doctoral thesis".
This seminar demonstrates how to approach the doctoral thesis in a professional way. Project management tools and techniques are used, tailored to the specific situation of PhD students. You will learn how to set a project vision, define clear objectives, gain buy-in from your supervisor and other colleagues in your group, and how to develop a project plan, which is structured and at the same time flexible enough to easily adjust to unexpected findings. You will establish a "controlling cycle" which helps you to recognise risks and problems as early as possible, and you will learn how to manage critical situations and deal with ups and downs. Furthermore, networking with colleagues, supervisors and other people are important topics of this seminar.
Throughout the seminar, you will work on your own doctoral thesis and share your experience with others. This seminar is most beneficial for PhD students who are in the early phases of their doctoral thesis. At the end of the seminar you will have established a strategy on how to approach your own doctoral thesis. During the follow-up REVIEW we will share experience and best practices and deal with open questions from the first module.
This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time.
You will also learn and practise the basic concepts of project management – a prerequisite in industries and research institutions.

Digital documentation and preservation is a key knowledge for archaeologists, no matter in which research area they are working in. This summer school gives a short introduction in the main digital methods currently used along with practical experience in real environments producing real data. The methods we want to show you are broad:

Structure from motion: This method uses a series of images to create 3D models. Can be used for small finds to whole buildings (with drones)
Drones: With drones, Structure from motion can acquire whole buildings or even landscapes. Several methods, from fixed wing (small airplanes) to multirotor drones will be shown.
Laser scanning: This device can create high precision point clouds in very short time and is very useful for all kind of documentation tasks.
Structured light scanner: This device is especially suited for small finds and objects. It projects actively light on the object to detect surfaces. The precision and quality is very high.
David scanner: A low-budget version of the Structured Light Scanner using laser beams. The results are very good.
Ground Penetrating Radar: Makes structures in the earth visible without excavating. One of the so called “non invasive methods”
Analysis of airborne LiDAR: Covering large areas, airborne LiDAR can help to detect a lot of archaeological remains, even in forested areas.

The quest for the wiring diagram of the brain
[]
Talk
Speaker: Prof. Fred Hamprecht
Location: Kirchhoff-Institute for Physics, Lecture Hall 2, INF 227
Link:
ECTS: not yet determined

Understanding the brain is an old and yet-unsolved problem. To understand the workings of a neural circuit, it is possibly required to know its structure, and almost surely necessary to know its connectivity.
After great progress in electron microscopy, several labs worldwide are milling away at animal brains and generating what will amount to petabytes of high-quality data. The resulting images are good enough for human tracers to consistently follow at least the majority of neural processes; unfortunately, humans would take thousands of years to complete the task for even the smallest mammalian brain.
So the quest is on for computer vision algorithms to do the same automatically and reliably. The current state of the art pipelines recur to deep neural networks and combinatorial graph partitioning problems. The former are notoriously ill understood, the latter still expensive to solve at scale.
In this talk, I will sketch the problem, a state of the art approach (which does not quite achieve human accuracy yet), and I will lay out some of the open problems in the field.

Interdisciplinary Seminar Series "Structures & Mathematics":

The workshop-seminars aim at initiating interactions between mathematicians and researchers from other sciences. We want to explore in particular questions and problems, which might be of interest to and benefit from the involvement of mathematicians of all sort.

Asymptotic structure of a steady fluid flow around a rotating body
[]
Talk
Speaker: Prof. Mads Kyed
Location: Mathematikon, Conference Room 5.104, Im Neuenheimer Feld 205, 69120 Heidelberg
ECTS: 0

Consider a rigid body that is fully submerged in a viscous fluid whose motion is governed by the Navier-Stokes equations.
I will discuss the asymptotic structure at spatial infinity of a steady flow around the body. In the 3D irrotational case, this classical problem has been almost fully resolved over the years, but many questions are still open in the 2D case. Indeed. the asymptotic structure of a 2D Stokes flow is closely related to the Stokes Paradox. In my talk, I will focus on bodies that are rotating with a constant angular velocity and discuss some new results for rotating planar flows.

Hyperbolic Approximation of the Vlasov equation and Kinetic approximation of non-linear hyperbolic systems
[]
Talk
Speaker: Laurent Navoret
Location: Mathematikon, Seminar Room 11, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

In this talk, we will give an overview of different numerical methods we propose to carry out efficient numerical simulations of the kinetic Vlasov equation and for non-linear hyperbolic equations. The Vlasov equation is a kinetic transport equation in the position-velocity phase space. The numerical resolution of the Vlasov equation requires large computational resources combined with high accuracy for capturing the small scale dynamics (phase-space filamentation, gyrokinetic turbulence). By performing a finite-element semi-discretization in the velocity variable, we approximate the Vlasov equation by a hyperbolic system. Applying mass-lumping techniques on the resulting system, the approximate Vlasov equation reduces to several coupled transport equations. We consider either semi-Lagrangian method on Cartesian meshes or Galerkin-Discontinuous solver on multi-patch structured meshes to achieve high order accuracy in space. As an inverse strategy, we approximate non-linear hyperbolic equations by linear kinetic transport equations with a finite set of velocities and stiff relaxation (Lattice Boltzmann Method). Implicit resolution of the transport equations (by front tracking), combined with palindromic composition method in time (of order 2, 4 or 6) enables us to use large CFL numbers while being well adapted to parallelization.
In this talk I will give a basic introduction to multilevel Monte Carlo methods applied to uncertainty quantification problems in PDE applications. I will aim the talk at numerical analysts and computational scientists, familiar with numerical methods for partial differential equations. I will only assume basic knowledge of probability theory. A particular focus will be the study of the inverse problem, where PDE models with random coefficients that encapsulate the prior knowledge about the coefficient distribution are coupled with measurement data of functionals of the PDE solution. The talk will focus mainly on methodology, but I will refer to some theoretical results that underpin the new methods, as well as stress some open theoretical and computational problems.

Computational modeling has become more and more important in the life sciences. One important class of models are compartment models and ordinary differential equations are widely used to describe the time evolution of the model_s components in a deterministic way. This compact course will introduce stochastic compartmental modeling. The objectives of the course are to learn a) methods that allow to simulate stochastic models and b) which effects so called intrinsic stochasticity can have on systems_ dynamics. These effects will make it evident that specific calibration techniques are needed in order to be able to cope with stochastic effects and exploit their information. The course will c) give a flavor of how calibration can be performed. Time will also be devoted to let the participants learn d) when stochastic modeling is necessary and beneficial.
This course will consist of lectures as well as practical exercises. Therefore, participants are encouraged to bring laptops (please contact me in case laptop sharing is desired). There is no prior software or programming experience necessary.

What is Non-Linear Preconditioning?
[]
IWR Colloquium
Speaker: Prof. Martin Gander
Location: Mathematikon, Conference Room / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

The idea of preconditioning iterative methods for the solution of linear systems goes back to Jacobi (1845), who used rotations to obtain a system with more diagonal dominance, before he applied what is now called Jacobi_s method. The preconditioning of linear systems for their solution by Krylov methods has become a major field of research over the past decades, and there are two main approaches for constructing preconditioners: either one has very good intuition and can propose directly a preconditioner which leads to a favorable spectrum of the preconditioned system, or one uses the splitting matrix of an effective stationary iterative method like multigrid or domain decomposition as the preconditioner.

Much less is known about the preconditioning of non-linear systems of equations. The standard iterative solver in that case is Newton_s method (1671) or a variant thereof, but what would it mean to precondition the non-linear problem? An important contribution in this field is ASPIN (Additive Schwarz Preconditioned Inexact Newton) by Cai and Keyes (2002), where the authors use their intuition about domain decomposition methods to propose a transformation of the non-linear equations before solving them by an inexact Newton method. Using the relation between stationary iterative methods and preconditioning for linear systems, we show in this presentation how one can systematically obtain a non-linear preconditioner from classical fixed point iterations, and present as an example a new two level non-linear preconditioner called RASPEN (Restricted Additive Schwarz Preconditioned Exact Newton) with substantially improved convergence properties compared to ASPIN.

Modelling glioma growth with fully anisotropic diffusion
[]
Talk
Speaker: Prof. Thomas Hillen
Location: Mathematikon, Conference room, 5th floor
Link:
ECTS: 0

The human brain has a complex geometric structure consisting of white and gray matter, blood vessels, ventricles, skull etc. It forms a highly anisotropic medium. Glioma in the brain are known to invade along white matter tracks and along other brain structures. Using diffusion tensor imaging (DTI) it is now possible to obtain directional information of the brain geometry. In my talk I will show how this DTI information can be used to parametrize a fully anisotropic diffusion equation for glioma spread. We validate the model on clinical data of glioma patients and discuss the future use in treatment design. (joint work with A. Swan, K.J. Painter, C. Surulescu, C. Engwer, M. Knappitsch, A. Murtha).

Deep Learning with Dense Connectivity
[]
IWR Colloquium
Speaker: Prof. Kilian Weinberger
Location: Mathematikon, Conference Room / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

Although half a decade has passed since Frank Rosenblatt_s original work on multi-layer perceptrons, modern artificial neural networks are still surprisingly similar to his original ideas.

In this talk I will give a brief introduction on deep neural networks and will question one of their most fundamental design aspects. As networks have become much deeper than had been possible or had even been imagined in the 1950s, it is no longer clear that the layer by layer connectivity pattern is a well-suited architectural choice. In the first part of the talk I will show that randomly removing layers during training can speed up the training process, make it more robust, and ultimately lead to better generalization. We refer to this process as learning with stochastic depth -- as the effective depth of the networks varies for each minibatch. In the second part of the talk I will propose an alternative connectivity pattern, Dense Connectivity, which is inspired by the insights obtained from stochastic depth. Dense connectivity leads to substantial reductions in parameter sizes, faster convergence, and further improvement in generalization. Finally, I
will show examples of problems that were considered challenging but have become surprisingly easy in the light of deep learning.

ECTS: not yet determined

The Center for Digital Research in the Humanities (CDRH) at the University of Nebraska-Lincoln (UNL) - founded in 2005 - was one of the earliest Digital Humanities (DH) centers in the world, and is supported by the University as a Center of Excellence as well as by private funds and grants. The Center is a founding member of centerNet, an international network of digital humanities centers, and is an institutional member of the TEI Consortium, the National Humanities Alliance, and the National Humanities Alliance. While the Center’s roots are in Library Science and English, the mission of CDRH is to promote collaborative and transdisciplinary digital humanities research. The Center houses over fifty scholarly projects ranging in scale, topic, and purpose. In the first part of the talk, I will present an overview of these diverse projects, some of their challenges, and their wide-spread impact in the humanities and beyond.

In the second half, I will focus specifically on Digital Cultural Heritage (DCH). Recent DH cluster hires in Anthropology, Classics & Religious Studies, History, and Art & Art History at UNL are facilitating innovative research in DCH. In particular, CDRH scholars are applying and developing Geographic Information Systems (GIS), 3D Modeling, and Virtual Reality (VR) methods and tools to foster new avenues of scholarly research. Underlying much of this research is the need to unite quantitative and qualitative data—requiring new computational methods and 3DGIS tools. I will present some of my experiences, outcomes, and ongoing challenges for three DCH projects — MayaArch3D (2009-2015), MayaCityBuilder (2016-present), and Keeping Data Alive (2017-present) - situating them within the larger framework of Digital Humanities.

Biography:
Heather Richards-Rissetto is an archaeologist specializing in the ancient Maya of Central America. She is Assistant Professor in Anthropology, a Faculty Fellow in the Center for Digital Research in the Humanities (CDHR), and holds a Courtesy Appointment in the School of Natural Resources (SNR) at the University of Nebraska-Lincoln. She received her Ph.D. in Anthropology from the University of New Mexico and her undergraduate degree in Anthropology and Geography from the University of Southern Maine. She uses Geographic Information Systems (GIS) and 3D visualization to investigate how the accessibility and visibility of architecture communicated information and structured social experience and sent political and ideological messages in past societies. She is the Director of the MayaCityBuilder Project that uses procedural modeling for 3D Visualization, Analysis, and Discourse on Ancient Maya cityscapes. The MayaCityBuilder Project builds on the data and results of the MayaArch3D Project (2009-2015) — of which she was the GIS Director. She is also the CoPI on the Project “Keeping data alive: Supporting reuse and repurposing of 3D data in the humanities” — supported by a National Endowment for the Humanities (NEH) Tier I Research and Development Grant, Division of Preservation and Access.

I will present a survey of the main results about first and second order models of swarming where repulsion and attraction are modeled through pairwise potentials. We will mainly focus on the stability of the fascinating patterns that you get by random particle simulations, flocks and mills, and their qualitative behavior. Qualitative properties of local minimizers of the interaction energies are crucial in order to understand these complex behaviors. Compactly supported global minimizers determine the flock patterns whose existence is related to the classical H-stability in statistical mechanics and the classical obstacle problem for differential operators.

Cell nuclei are not always spherical; some are highly irregular. The structural basis for this multiplicity of shapes appears to derive from the components of the nuclear envelope and their interactions with cytoskeletal elements. Describing these shapes mathematically is a challenge; explaining their biochemical origin remains a mystery. The goal of this seminar is to discuss aspects of these problems and to provoke comments and ideas from the audience.

Kognitives Stressmanagement
[]
Workshop
Speaker: Dipl.-Psych. Walter Ph. Krämer
Location: Im Neuenheimer Feld 205, SR 11
ECTS: 0

Die Bedeutung der mentalen Leistungsfähigkeit nimmt im Wandel der kognitiven Anforderungen einer modernen Arbeitswelt stetig zu. Der Zusammenhang von psychomentaler Überlastung und kognitiven Einschränkungen wird häufig unterschätzt, besonders bei Menschen mit hohem Leistungspotenzial bzw. im Rahmen anspruchsvoller beruflicher Tätigkeiten.
Als Weiterführung der Veranstaltung im Oktober 2016 wird im aktuellen Vortrag insbesondere das kognitive Stressmanagement im Vordergrund stehen.
Einführend soll ein Modell des Nobelpreisträgers Daniel Kahnemann Aufschluss geben, von welchen inneren Faktoren unser Denken und unsere Bewertungsstrategien abhängig sind und in welcher Weise unsere Emotionen unser Denken beeinflussen. Ein Abriss über kognitive Verzerrungen wird veranschaulichen, wie unsere Bewertungen und Schlussfolgerungen im Alltag beeinflusst bzw. verzerrt werden. Als Impuls für einen besseren Umgang mit unserem Denken werden unterschiedliche kognitive Strategien anhand praktischer Beispiele vorgestellt und diskutiert.
Abschließend werden wir der Frage nachgehen, warum Menschen manchmal völlig fern jeder Vernunft handeln, obwohl sie es „eigentlich-besser-wissen- müssten“.
Es werden keine Vorkenntnisse vorausgesetzt.

ECTS: 0

Gene expression occurs in an environment in which both stochastic and diffusive effects are significant. Spatial stochastic simulations are computationally expensive compared to their deterministic counterparts and hence little is currently known of the significance of intrinsic noise in a spatial setting. I will show how starting from the reaction-diffusion master equation (RDME) describing stochastic reaction-diffusion processes, we can derive closed-form expressions for the approximate steady-state mean concentrations which are explicit functions of the dimensionality of space, rate constants and diffusion coefficients. These are generally different from those given by the deterministic theory of reaction-diffusion processes, thus highlighting the importance of intrinsic noise. Our theory is confirmed by comparison with stochastic simulations, using the RDME and Brownian dynamics, of two models of stochastic and spatial gene expression in single cells and tissues. Lastly, time permitting, I will discuss how one can extend these results to stochastic spatial simulations of intracellular processes which take into account macromolecular crowding, namely the volume exclusion due to the finite size of molecules.

Discussion with the speaker after the talk (at around 12:00), coffee will be provided.

Music Information Retrieval - When Music meets Computer Science

IWR Colloquium
Speaker: Prof. Meinard Müller
Location: Mathematikon, Conference Room / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

Significant digitization efforts have resulted in large music collections, which comprise music-related documents of various types and formats including text, symbolic data, audio, image, and video. In the field of music information retrieval (MIR) great efforts are directed towards the development of technologies that allow users to access and explore music in all its different facets. For example, during playback of some CD recording, a digital music player may present the corresponding musical score while highlighting the current playback position within the score. On demand, additional information about melodic and harmonic progression or rhythm and tempo is automatically presented to the listener. A suitable user interface displays the musical structure of the current piece of music and allows the user to directly jump to any key part within the recording without tedious fast-forwarding and rewinding. In this talk, I discuss a number of current research problems in the field of music information retrieval and indicate possible solutions. One fundamental problem is to decompose a given music signal into semantically meaningful components. To guide the decomposition, one may exploit additional information, either in the form of specific acoustic properties of the components or in the form of additional score information. As an example, I show how to compute a notewise decomposition of a music signal by applying a score-informed variant of non-negative matrix factorization (NMF). Finally, I discuss various audio editing and manipulating applications to highlight the potential of these decomposition techniques.

We consider the question of when delay systems, which are intrinsically infinite dimensional, can be represented by finite dimensional systems. Specifically, we give conditions for when all the information about the solutions of the delay system can be obtained from the solutions of a finite system of ordinary differential equations. For linear autonomous systems and linear systems with time-dependent input we give necessary and sufficient conditions and in the nonlinear case we give sufficient conditions. The ideas and results are illustrated by models for infectious diseases and physiologically structured populations.

ECTS: not yet determined

To fully utilise computational resources for applications based on Discontinuous Galerkin discretisations, efficient and algorithmically optimal implementations are necessary. Traditionally a given PDE is solved by assembling a system of sparse equations and inverting the resulting matrix equation algebraically, for example with an AMG method. However, on modern multicore chip architectures with a poor FLOP-to-bandwidth ratio this approach becomes very expensive. Let N denote the number of unknowns per element. To apply the operator, in each grid cell a matrix of size N x N has to be loaded from memory and a dense matrix-vector multiplication with low arithmetic intensity is carried out; the overall cost of the method is O(N^2). This cost is reduced by matrix-free implementations where the matrix is re-calculated on-the fly. For tensor-product elements in d dimensions sum factorisation techniques reduce the computational complexity from O(N^2)=O(n^{2d}) to O(d*n^{d+1}), where n is the number of unknowns in one direction.

In preconditioned Krylov-subspace solvers and multigrid smoothers it is often necessary to invert block-diagonal matrices. Even though the action of A is implemented in a matrix-free way, local block-matrices D_e of size n^d x n^d are assembled in each cell and then inverted with an exact LU- or Cholesky-factorisation. Overall this requires O(n^{2d}) bandwidth-bound operations and quickly becomes the bottleneck of the solver as the order n increases. To circumvent this problem, we solve the system D_e.x=y approximately with an iterative method. Since the application of D_e can be implemented in a matrix-free way, the action of D_e^{-1} becomes FLOP bound and the cost decreases from O(n^{2d}) to O(n_{iter} * d * n^{d+1}) where n_{iter} is the number of iterations required to solve the system in each cell.

We study the efficiency of this approach for the solution of linear convection-diffusion systems; problems of this type arise, for example, in operator splitting approaches for unstable porous media flow. We demonstrate the algorithmic and computational efficiency of the method for a hybrid multigrid algorithm with hp-coarsening, similar to [Bastian et al. (2012), Num. Lin. Alg. with Appl. 19 (2), pp. 367-388]: on the finest level a matrix-free block-Jacobi or block-SSOR smoother is applied to the high-order system, and the low-order system on the coarser levels is solved with AMG.

All code is implemented in the EXADUNE code base and we demonstrate the efficiency of our approach for a range of elliptic PDEs, including a convection-dominated problem and the stationary SPE10 benchmark.

ECTS: not yet determined

The flows in close proximity to the air-sea interface control the exchanges between the atmosphere and the ocean, such as gases, heat, vapor, and momentum. The scales of the flow motions, including surface waves and turbulence, are much smaller than that of the atmosphere and the ocean. The processes within this surface layer, however, can profoundly affect the large-scale geophysical flows. The topic has been studied mainly by experimental measurements in the field and laboratory. Numerical simulation provides a complementary tool to reveal the underlying physics, but also pose challenges to the computations due to the inherent nonlinearity of the free boundary and the distinct length/time scales in the turbulent flow and wave motions. In this talk, I will briefly review the numerical method we have developed to solve this free-boundary problem. I will then present recent progress in evincing new physics in microscale air-sea interaction using numerical simulation. These studies are either aimed to elucidate previously unexplained observations or motivated/inspired by the recent innovative measurements.

Simple mathematical models for personalized oncology

Location: Mathematikon (INF 205) Konferenzraum (5th floor)
ECTS: not yet determined

Mathematical models of tumor dynamics have become more accurate and accepted in recent years and enable a better prediction of initiation and development of a tumor, as well as its response to therapy. Using models one can compare different approaches or design new treatment strategies, which then can be tailored to individual patient data.

I will present some simple mathematical models for different problems in oncology; preventive gastric cancer screening, head and neck cancer response to radiation therapy, and combination therapies for pancreatic cancer. Mathematical models will be fit to retrospective clinical training data to derive parameter distributions for each participating mechanism. Parameter distributions with small variation will be collapsed into uniform rate constants, leaving variable mechanisms that are most likely to determine patient-specific outcomes. Calibrated models will be validated on independent training data, before virtual "in silico" trials determine optimal treatment protocols on a per patient basis.

Additional information:
After the talk there will be a meetup with the speaker to discuss different subjects in the area of cancer modelling. Discussion topics will include the impact of mathematical and computational models in the clinic, the challenges of interdisciplinary collaboration, and the current hot research topics. The meetup is tailored to provide a relaxed atmosphere where graduate students can have an introspect discussion of the field. Dr. Enderling will also address questions such as:
- What would you have wanted to know when you started working in this field?
- What are the "dos" and "don_ts" for PhD students starting their research in this field?
Master and PhD students are highly encouraged to attend.

GASPI Tutorial

Practical
Location: Computing Center of Heidelberg university
ECTS: not yet determined

In this tutorial we present an asynchronous data flow programming model for Partitioned Global Address Spaces (PGAS) as an alternative to the
programming model of MPI. GASPI, which stands for Global Address Space Programming Interface, is a partitioned global address space (PGAS) API.
The GASPI API is designed as a C/C++/Fortran library and focused on three key objectives: scalability, flexibility and fault tolerance. In
order to achieve its much improved scaling behaviour GASPI aims at asynchronous dataflow with remote completion, rather than
bulk-synchronous message exchanges. GASPI follows a single/multiple
program multiple data (SPMD/MPMD) approach and offers a small, yet
powerful API (see also www.gaspi.de and www.gpi-site.com). GASPI is successfully used in academic and industrial simulation applications.
Hands-on sessions (in C and Fortran) will allow users to immediately test and understand the basic constructs of GASPI. This course provides
scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.

Please note that for the excercises the user needs to bring an own laptop and to already have access to either the bwUniCluster [1] oder the bwForCluster MLS&WISO Production [2] in Heidelberg/Mannheim. Please notify us in case of any problems. The course language is German (the slides are in English) or English if required.

In this talk, we address several aspects of model and cost reduction techniques for the numerical simulation of PDEs. Firstly, we consider tearing and interconnection strategies in combination with interface models and reduced basis methods. These techniques are of special interest in the case of vibro-acoustic simulation and can largely reduce the number of degrees of freedom. Numerical results in case of orthotropic material laws are given for a violinbridge as well as a timber building.
Secondly, we discuss surrogate models which aim at a complexity reduction. Here we introduce locally mass conservative scheme in a local postprocessing step as well as adaptive control techniques for resilient multigrid solvers. In all cases, we provide the numerical analysis, algortihmic aspects and illustrative large scale results.

Interior point methods are well-suited for solving multistage stochastic
NLPs when an efficient algorithm for the huge structured KKT systems is
available. This is the case for large scenario trees with a moderate
number of variables per node: we present a distributed ``tree-sparse__
solution algorithm based on a static partitioning of the tree and
featuring low memory and communication overheads. We also address
structured quasi-Newton updates for the sparse Hessian as well as
structured inertia corrections to address non-convexity or
rank-deficiency of the KKT system.
Computational results for benchmark problems from portfolio optimization
and robust model predictive control demonstrate the performance of our
approach.

Method of multiple shooting for computing shortest descending paths on convex terrains
[]

Speaker: Prof. Phan Thanh An
Location: Mathematikon, Seminar Room SR 11, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

Given a polyhedral terrain and two points p, q on the terrain, a path joining p to q on the terrain is descending if the z-coordinate of a point v never increases while we move v along the path from p to q. The problem of finding shortest descending paths joining two given points on a polyhedral terrain was posed first by de Berg and van Kreveld (in Algorithmica, 18 (1997), pp. 306-322). Recently, the problem of finding approximations of such paths is considered by Ahmed, Lodha, and Lubiw (2010), Wei and Joneja (2013), Cheng and Jin (2014), etc. using Steiner point, graph, and sequence tree techniques.

In this talk we introduce the method of multiple shooting for solving the problem. It includes the factors: (f1) partition of the terrain, (f2) the straightness condition for the shortest descending paths at shooting points, and (f3) update of shooting points. In particular, the method does not rely on Steiner point, graph and sequence tree techniques on the entire terrain. If the straightness condition is satisfied then we obtain a local shortest descending path.

The corresponding algorithm is implemented in C++ using CGAL. Numerical results nonetheless indicate that the result is close to a local shortest descending path, even if it does not fulfil the straightness condition.

Dimension reduction or feature selection is an effective strategy to handle contaminated data and to deal with high dimensionality while providing better prediction. To deal with outlier proneness and spurious variables, we propose a method performing the outright rejection of discordant observations together with the selection of relevant variables.
To solve this problem, it is recasted as a mixed integer program which allows the use of efficient commercial solver. Also we propose an alternate projected gradient algorithm (proximal) so get a nice appoximated solution.

Machine Learning is the science and art of extracting meaningful information from data. In supervised machine learning, we use a training set of annotated examples to teach a computer to make valid predictions, or to reliably recognize items. In unsupervised learning, we use computers in an exploratory fashion, to discover interesting patterns in data.

Machine learning and pattern recognition are currently taking center stage in applications ranging from autonomous driving to social network analysis and drug development.

This seminar covers the essential techniques typically taught in an introductory lecture, including

statistical learning theory
generative and discriminative classifiers
ridge regression, lasso
logistic regression, generalized linear models
kernel methods, support vector machine
perceptron, multi-layer perceptron, neural networks
dimension reduction
cluster analysis

Mathematical modeling and numerical analysis for incommensurate 2D materials
[]
Talk
Speaker: Prof. Mitchell Luskin
Location: Mathematikon, Konzerenzraum 5.OG
Link:
ECTS: 0

The unique electronic, optical, and mechanical properties of 2D materials have sparked an extraordinary level of theoretical and experimental activity. Stacking a few layers of 2D materials such as graphene and molybdenum disulfide, for example, opens the possibility to tune the electronic and optical properties of these materials. One of the main issues encountered in the mathematical and computational modeling of layered 2D materials is that lattice mismatch and rotations between the layers destroy the periodic character of the system.

Even basic concepts like the Cauchy-Born strain energy density, the electronic density of states, and the Kubo-Greenwood formulas for transport properties have not been given a rigorous analysis in the incommensurate setting. New approximate approaches will be discussed and the validity and efficiency of these approximations will be examined from mathematical and numerical analysis perspectives.

"Feedforward and feedback learning in sensorimotor control"
[]
Talk
Speaker: Dr. David Franklin
Location: Seminar Raum A im Mathematikon Bauteil A
ECTS: not yet determined

The human sensorimotor control system has exceptional abilities to perform skilful action despite ever changing conditions. I will discuss
how this adaptability can result through intrinsic feedback mechanisms in two different ways: sensory feedback driving feedforward adaptation;
and feedforward adaptation in turn adapting the feedback responses and tuning them to the environment. In the first part of my talk I will
examine how prior sensorimotor cues can be used to learn independent motor memories. These results suggests that motor memories are encoded
not simply as a mapping from current state to motor command but are encoded in terms of the recent history of sensorimotor states. However
learning can also be used to adjust intrinsic feedback control. The second half of my talk will focus on a few recent studies examining
feedback responses; demonstrating both how they are modulated for control and using them to probe the underlying mechanisms of visually
guided reaching. Finally I will present work demonstrate that the visuomotor feedback gain shows a temporal evolution related to task
demands (as predicted by optimal control) and that this evolution can be flexibly recomputed within 100 ms to accommodate online modifications to
task goals.

Root Functions: A Special Class of Boolean Functions
[]
Talk
Speaker: Professor Debesh K. Das
Location: Mathematikon, Seminar Room SR 10 / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
ECTS: not yet determined

The talk introduces a special class of Boolean functions known as root functions. We show that there exists such class of Boolean functions, which can never appear as faulty response in irredundant two-level AND-OR combinational circuits even when any arbitrary multiple stuck-at faults are injected. Conversely, we show that any other Boolean function can appear as a faulty response in an irredundant realization of some root function under certain stuck-at faults. We characterize this new class of functions and explore their different properties. We show that for n variables, their number is exactly equal to the number of independent dominating sets in a Boolean n-cube. Also, we show that an n-variable root-function with minimum number of true minterms, where n = 2k - 1; k > 2, possesses some inherent error detection/correcting properties.

Dr. Debesh K. Das received the B.E. and M.E. degrees in electronics and telecommunication engineering and the Ph.D. degree in Engineering from Jadavpur University, Calcutta, India. He is currently with the Department of Computer Science and Engineering, Jadavpur University, as a Professor. Prior to this, he served as Minister-in-Charge of Information Technology in the Govt. of West Bengal. His research interests include logic synthesis and testing of VLSI circuits and fault-tolerant computing. He has published more than 100 papers in reputed Journals and International Conference Proceedings.

Interdisciplinary Seminar Series "Structures and Mathematics“: Neuronal ensembles as elementary representations in the nervous system
[]
Public Talk
Speaker: Prof. Dr. med. Andreas Draguhn
Location: Mathematikon, Lecture Hall / Ground Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:
ECTS: not yet determined

Studies of the nervous system are performed at multiple system levels, beginning with the structure and function of single molecules (e.g. ion channels), electrochemical processes at the level of single cells (e.g. generation of action potentials, synaptic transmission), activity in multi-neuronal networks (e.g., processing of visual inputs in the retina), large-scale spatiotemporal patterns in the nervous system (e.g., brain-wide activation patterns during cognitive task performance) and, ultimately, at the cognitive-behavioral level of the whole organism (perception, motion, decision making, emotions etc.). In real live, processes at all these levels work together, such that simple bottom-up or top-down models of brain function are far too simple.

This complexity is one of the reasons why mathematical approaches are indispensable in modern neuroscience. We are dealing with highly parallel data, e.g. simultaneous recordings from multiple neurons in electrophysiology, or from millions of volume elements in functional brain imaging. In addition, the emergent properties of complex systems like neuronal networks cannot be simply predicted from linear causal relations and, thus, are often inferred from computer simulations. Third, we are beginning to reveal more and more structural details of the brain – the functional consequences of these boundary conditions are again a topic for mathematicians and network scientists.

In my presentation, I will exemplify some major research problems and approaches of modern neuroscience, focusing on the level of neuronal networks. Our leading question is: How does the brain represent a perception, a memory, a planned action or a motor program? Most neuroscientists agree that this ‘coding’ is performed by multiple cells which are co-activated in a reproducible manner. These sets of neurons are called ensembles or, in other research traditions, assemblies. They can be reproducibly activated even by incomplete input patterns, forming stable spatio-temporal structures or (in one specific approach) attractors in the network’s state-space. In most cases, activation of ensembles happens on top of synchronous network oscillations which provide a temporal scaffold (or ‘clock’) for coordination of the multi-neuronal activity pattern.

In this presentation, we shall discuss the concept of ensembles and its implications for the multiplicity, stability and plasticity of different representations. We will highlight some specific questions based on own and other’s data, mainly from memory-forming networks in the rodent hippocampus. Key questions are: What are the key properties of hippocampal ensembles? How are single neurons bound into reproducible spatiotemporal patterns? How are non-participating neurons reliably suppressed during activation of a given ensemble? How are local ensembles bound into large-scale functional networks?

All of these questions require multidisciplinary approaches including cell and systems physiology, behavioral neurosciences and, importantly, advanced data analysis and mathematical modelling. The importance of (and sometimes lack of) generally accepted quantitative models of neuronal networks, their cellular constituents and their large-scale effects will become clear from each of the multiple open questions mentioned during the presentation.

ECTS: not yet determined

Math Goes Public lectures address a wide audience in natural and social sciences and engineering: They show how Mathematics helps explaining many different phenomena. I present dew drops on spider webs, a beautiful example for nonlinear problems. In these problems different components inter react, defining one of the most fascinating areas of modern Mathematics. Locally like linear problems, fascinating unexpected scenarios of new critical solutions with new properties do occur: The original symmetry or stability of solutions gets lost, called symmetry or stability breaking bifurcation with structural consequences. Why are only lines of drops observed along spider threads? We present the essential aspects of a mathematical model with very interesting mathematical challenges and the corresponding numerical methods yielding some plots. This complicated problem has never been studied before. In Marburg Karlheinz Schild, Bernhard Schmitt and I made it.

HGS MathComp Ladyshenskaya Lecture

Although in nature there is nothing really unbounded problems for partial differential equations in unbounded domains are often used to model certain geometries. Thereby the behavior at infinity of the solutions plays an important role in the modeling process. For elliptic problems, including the stationary Stokes system in particular, a broad theory exists for various kinds of unbounded domains. There results on spatial asymptotics typically appear as a decomposition of the solution into explicitely known terms and a remainder with corresponding estimates. In contrast to this very little is known about time dependent problems. Here we consider time periodic solutions to the Stokes problem in a layer where the data are also time periodic and smooth with bounded support for simplicity.

We will look at progress in Linear Programming (LP) and Mixed Integer Programming (MIP) software over the last 25 years. As a result of this progress, modern LP codes are capable of robustly and efficiently solving instances with multiple millions of variables and constraints.

With these LP advances as a foundation, MIP provides the modeling framework and the key solution technology behind prescriptive analytics. The performance improvements in MIP codes have been nothing short of remarkable, well beyond those of LP, and have transformed this technology into an out-of-the box tool with an almost unlimited range of real-world applications.

Interactive physics-based simulations are now capable of reproducing a growing number of motion skills, often with a focus on generating agile-and-robust locomotion. In this talk, I review recent progress in simulation-based models of human and animal motion as used for computer animation, where they seek to replace simpler kinematic models based on motion-capture.

We will discuss the roles of optimization, machine learning, and simplified models in these approaches, as well as what insights might be shared between robotics and our simulation-based work in animation. A wide variety of animated results will be shown to illustrate the capabilities of current methods. I_ll also identify several research directions where we still need to see significant progress.

Robust Visual Perception for Intelligent Systems
[]
Talk
Speaker: Dr. Andreas Geiger
Location: Mathematikon (Building B), Seminar Room / 3rd Floor
ECTS: not yet determined

Perception is a key component of every intelligent system as it enables actions within a changing environment. While humans perceive their environment with seemingly little efforts, computers first need to be trained for these tasks. One of the biggest challenges in computer vision are ambiguities which arise due to the complex nature of our environment and the information loss caused by observing two-dimensional projections of our three-dimensional world. In this talk, I will present several recent results in stereo estimation, 3D reconstruction and motion estimation which integrate high-level non-local prior knowledge for resolving ambiguities that can´t be resolved using local assumptions alone. Furthermore, I will discuss the "curse of dataset annotation" and present a method for augmenting video sequences efficiently with semantic information.

Bewerbung, Vorstellungsgespräch, Einstiegsgehalt - Todsünden und Tugenden
[]
Key Competences
Speaker: Michael Müller, Diplom-Volkswirt
Location: Mathematikon, Im Neuenheimer Feld 205, 5. Stock, Seminarraum 10
ECTS: 1

Ziel des Workshops ist es, vom Lebenslauf über das Vorstellungsgespräch bis zur Frage nach dem Gehalt optimal vorbereitet zu sein.
Bewerben ist wie flirten: Wer zu langweilig und 08/15 ist oder den falschen Ton trifft, wird abgewiesen. Zwei Vorgehensweisen können nun angewandt werden: die quantitative oder die qualitative Strategie.
Die quantitative Strategie bedeutet: mehr schlechte Bewerbungen schreiben. Sprich: einfach mehr flirten in der Hoffnung, dass auch ein blindes Huhn mal ein Korn findet.
Die qualitative Strategie verspricht, durch eine kluge Bewerbung und souveränes Auftreten in den Gesprächen mehr Erfolg zu haben. Das bedeutet beim Bewerben wie beim Flirten: mehr Auswahl. Um letztere Strategie dreht sich das Seminar.

Inhalt:
-Was unterscheidet eine gute von einer schlechten Bewerbung?
-Wie denkt der Personaler?
-Das Vorstellungsgespräch aus beiden Perspektiven beleuchtet.
-Die typischen Stressfragen und die typischen Fehler des Bewerbers.
-Wie viel Gehalt kann ich verlangen?

Nach dem Seminar werden die Teilnehmer:
-Bessere Bewerbungen schreiben können.
-Mehr Einladungen zu Vorstellungsgesprächen haben.
-Im Vorstellungsgespräch punkten und aus der Masse hervorstechen.
-Im Stressinterview unter Druck gelassen bleiben.
-Gekonnt die Gehaltsfrage klären.

DUNE/PDELab Course 2016
[]
Compact Courses
Speaker: Various
Location: tba.
Link:
ECTS: 3

The Distributed and Unified Numerics Environment (DUNE) is a software framework for the numerical solution of partial differential equations with grid-based methods. Using generic programming techniques it strives for both: high flexibility (efficiency of the programmer) and high performance (efficiency of the program). DUNE provides, among other things, a large variety of local mesh refinement techniques, a scalable parallel programming model, an ample collection of finite element methods and efficient linear solvers.

DUNE-PDELab is a powerful tool for implementing discretisations of partial-differential equations. It helps to substantially reduce the time to implement discretizations and solvers for (systems of) PDEs based on DUNE. It is not only suitable for rapid prototyping but also for building highly performant simulation software and is used by a variety of projects already.

This one week course will provide an introduction to the most important DUNE modules and especially to DUNE-PDELab. At the end the attendees will have a solid knowledge of the simulation workflow from mesh generation and implementation of finite element and finite volume methods to visualization of the results. Topics covered are the solution of stationary and time-dependent problems, as well as local adaptivity, the use of parallel computers and the solution of non-linear PDE_s and systems of PDE_s.

Krylov subspace methods, their analysis and applications

Location: IWR, Room 520, Im Neuenheimer Feld 368, 69120 Heidelberg
ECTS: 2

Krylov subspace methods are widely used for solving linear algebraic systems, approximating eigenvalues, and model reduction in science and engineering. This course will give a short overview of their mathematical foundations.

First, Krylov subspace methods use linear projections onto a sequence of finite dimensional subspaces. Since these subspaces are formed using repeated applications of the given matrix (operator) to a given initial vector, the methods are highly nonlinear. In fact, the nonlinearity allows for adaptation of the computation to the problem, which often results in an expected acceleration of convergence. If no substantial acceleration occurs and the results of the computation can be described using linear contractions, then one should ask whether the chosen Krylov subspace method is efficient for solving the given problem. The strong nonlinearity poses significant challenges for the analysis of the methods as well
as the understanding of effects of finite precision arithmetic in practical computations.

Different mathematical viewpoints and the resulting tools are used for analysis of Krylov subspace methods.The methods are closely linked with matching moments model reduction and quadrature. Spectral properties (eigenvalues and eigenvectors) of the matrix, together with the projections of the initial vector on the individual invariant subspaces, describe the convergence behavior, provided that the individual spectral invariant subspaces are mutually orthogonal. The general case is intriguing and still
far from being fully understood. Numerical stability of Krylov subspace methods is closely linked with the loss of orthogonality of the computed generating vectors, which is governed by different mechanisms for methods using short and long recurrences.

Finally, it is beneficial to consider formulations of Krylov subspace methods in infinite dimensional Hilbert spaces. That naturally leads to the concept of operator preconditioning. Preconditioning is a crucial part of computations using Krylov subspace methods; in most cases it is based on algebraic considerations and the discretized system of equations. Therefore it could be of interest to make a link between the operator and algebraic preconditioning.

The course will end with discussion of open questions.

Speaker: Dr. Christian Prager
Location: IWR, Raum 532, Im Neuenheimer Feld 368, 69120 Heidelberg
ECTS: not yet determined

Im Rahmen des Forschungsprojekts "Textdatenbank und Wörterbuch des Klassischen Maya" wird derzeit eine maschinenlesbare Annotation der Hieroglyphentexte auf der Grundlage von XML TEI konzipiert und entworfen. Ziel des strukturierten Markups der Mayaschrift ist es die Struktur der Originalschreibung und die Anordnung der Zeichen im Text möglichst genau mit Hilfe von TEI XML abzbilden. Bei partiell entzifferten Mayaschrift kommt das Problem hinzu, dass anstelle von Transliterationen und Transkriptionen unentzifferte Zeichen oder Textstellen mit Hilfe von Codes und Nomenklaturen wiedergegeben werden müssen um auf dieser Grundlage fragliche Zeichen in ihrem jeweiligen Verwendungskontext zu dokumentieren. Die Dokumentation der Originalschreibung ist grundlegend für die epigraphische Arbeit mit syllabischen und logo-syllabischen Hieroglyphen- und Keilschriftsystemen. Unser Projekt hat hier ein Desiderat für die vergleichende Schriftforschung erkannt und möchte in Zusammenarbeit mit Experten für kompexe Schriftsysteme Lösungen auf der Grundlage von XML TEI und Epidoc erabeiten. Im Rahmen des Vortrags in Heidelberg stellen wir die Probleme und Herausforderungen bei der Annotation der Mayaschrift vor.

Digitale Epigraphik - Die Erforschung der Hieroglyphentexte und Bildbotschaften der Maya in der virtuellen Forschungsumgebung TextGrid
[]
Talk
Speaker: Prof. Nikolai Grube
Location: IWR, Raum 532, Im Neuenheimer Feld 368, 69120 Heidelberg
ECTS: not yet determined

Die nur teilweise entzifferte Hieroglyphenschrift und Sprache der Mayakultur steht im Mittelpunkt eines Forschungsprojektes der NRW Akademie der Wissenschaften, das in Kooperation zwischen den Universitäten Bonn und Göttingen durchgeführt wird. Ziel ist die Erstellung einer Textdatenbank und ein darauf basierendes Wörterbuchs des Klassischen Maya. Im Rahmen des Projekts werden die Text- und Bildträger systematisch und nach einheitlichen Standards beschrieben, das Ausgangsmaterial auf der Basis von XML maschinenlesbar gemacht und auf diese Weise die Grundlagen für die Kompilation des Wörterbuchs geschaffen. Dieses Unterfangen wird mit Methoden und Technologien aus den digitalen Geisteswissenschaften in Angriff genommen. Wesentliche Voraussetzung ist dabei, dass nicht nur der sprachliche Inhalt der Inschriften und die ikonischen Informationen der Bilddarstellungen, sondern auch Daten über den Inschriften- und Bilddträger (Beschreibungs- oder Metadaten) berücksichtigt und in einer Datenbank angelegt werden. Zu diesem Zweck werden in TextGrid Tools und Workflows entwickelt, welche die I. Dokumentation der Schrift- und Bildträger mit Aufarbeitung des Forschungsstandes, II. die epigraphisch-linguistische Auswertung der Hieroglyphentexte sowie III. Edition der Texte mit Transliteration, Transkription und Übersetzung in einem einzigen System ermöglichen. Die VRE enthält nicht nur Beschreibungen der Textträger oder Informationen die Texte, sondern der Datenbanknutzer bekommt mit Hilfe der Literaturdatenbank auch einen Überblick darüber, welche Autoren sich mit einem Monument befasst oder es publiziert haben, eine Textpassage diskutiert oder erstmals eine bis heute gültige sprachliche Lesung einer Hieroglyphe präsentiert haben. Der Textträger erhält dadurch eine ‚Biographie‘, die eng mit dem Textinhalten verwoben ist und bei der Bedeutungsanalyse von Wörtern berücksichtigt wird.
