Subject: New Book, Inverse Problems with Applications in Science and Engineering


A new book in inverse problems has been published. Lesnic, D. (2021)
Inverse Problems with Applications in Science and Engineering}, CRC
Press, Taylor & Francis Group, Abingdon, UK. ISBN: 978-0-367-00198-8
(hardback), ISBN: 978-1-032-12538-1 (paper back), ISBN:
978-0-429-40062-9 (e-back). DOI: 10.201/9780429400629.

The book examines thoroughly some representative classes of inverse
and improperly-posed problems for partial differential equations
governing a wide range of physical phenomena. The natural practical
applications arise in heat transfer, electrostatics, porous media,
fluids and acoustics. Intended readers of the book include
postgraduate students and post- doctoral fellows from
qualitatively-oriented fields of mathematical sciences and
engineering, as well as scientists and researchers from either
academic and industrial settings, where inverse problems naturally
occur.

Subject: Data Science and PDE Analysis; Foundational ML, Germany, Jun 2022


We would like to draw your attention to the HCM Workshop Synergies
between Data Science and PDE Analysis to be held at the University of
Bonn in Germany on 13-17 June 2022.

The current success story of data science calls for interpretable
machine learning methods. For instance, in the context of sampling,
graph-based learning or neural networks, PDE-based methods have
proven to be both efficient and apt for mathematical analysis. This
workshop brings together experts and young researchers in these two
vibrant fields and aims to create a stimulating environment for
exchanging scientific ideas and establishing new collaborations.

An application is mandatory for participation. Deadline for
applications is February 15th, 2022 (CET). We also offer some spots
for contributed talks. A small number of additional fully funded
places are available for researchers facing financial burdens, such as
researchers from developing countries.

Please find further information at the website:
https://www.hcm.uni-bonn.de/de/veranstaltungen/eventpages/2022/syn-2022/

This workshop is organized in tandem with the Hausdorff School
Foundational Methods in Machine Learning to be held at the University
of Bonn in Germany on 6-10 June 2022.

The school will consist of special topics courses from the following
lecturers: Weinan E (Princeton University, USA); Carola Schoenlieb (
Jesus College Cambridge, UK); Dejan Slepcev (Carnegie Mellon
University, USA); Rachel Ward (The University of Texas, USA).

An application is mandatory for participation. Deadline for
applications is February 6th, 2022 (CET). A small number of additional
fully funded places are available for students and young researchers
facing financial burdens, such as researchers from developing
countries.

Subject: Random Matrix Theory and NLA, USA/HYBRID, Jun 2022


I am pleased to announce the Conference on Random Matrix Theory and
Numerical Linear Algebra (RMT + NLA) to be held at the University of
Washington, Seattle, June 20-24, 2022. We will offer a hybrid format,
so participants may connect remotely.

The conference aims to bring together researchers from areas such as
random matrix theory, numerical linear algebra, randomized algorithms,
high-dimensional statistics, optimization and theoretical computer
science to discuss recent developments and cutting-edge techniques.

The conference will feature two tutorials/minicourses from Ioana
Dumitriu (UCSD) and Sean O'Rourke (CU Boulder). The rest of the
conference will consist of research talks and a poster session.

More information, including registration details, can be found at the
conference website:
http://faculty.washington.edu/trogdon/RMT+NLA/index.html

We do have limited travel funding available that will be used
primarily to support junior researchers and an application for funding
can be submitted through the conference webpage with a deadline of
February 4, 2022.

We are also seeking applications to present a poster at the poster
session.

Subject: PhD Positions, Mathematical Biology, Kassel Univ


The University of Kassel establishes the interdisciplinary Research
Training Group (RTG) "Biological Clocks on Multiple Time Scales"
(http://www.uni-kassel.de/go/multiscale_clocks), which is funded by
the German Research Foundation from 1. April 2022 on. The RTG aims at
investigating the principles of timekeeping in living organisms,
enabling to orchestrate periodic processes with very different
frequencies ranging from infradian over circadian to ultradian
rhythms. The unique approach is to combine the expertise of
biologists, physicists, chemists, mathematicians, and engineers to
advance the understanding of biological clocks. The RTG comprises 13
projects, two of which are of a more mathematical nature: P9: Models &
simulations for new insights into physiology of clocks and ways of
adapting it (PI: Prof. Elfriede Friedmann) and P11: Model reduction
via symmetries and conservation laws for systems on multiple time
scales (PI: Prof. Werner M. Seiler). For these projects, we seek
outstanding research assistants with a master degree in mathematics or
in a closely related field. Advantageous are experiences in dynamical
systems, partial differential equations, finite element methods, Lie
symmetries, singular perturbation theory or programming. More details

on nonlocal software. The special issue will give users of the codes a
peer-reviewed reference to cite in their own future papers. The
articles for the special issue should contain basic information about
the codes and an example problem but are not required to provide an
in-depth treatment of the method. All types of discretizations and
methods are acceptable for submission (if you're in doubt, please,
reach out by replying to this email).

To submit a manuscript, go to the JPER website
https://www.springer.com/journal/42102 and select "Submit manuscript"
on the right. It is important to indicate that you are planning to
contribute to this specific special issue. To do so, during the
submission process, once you reach the tab "additional information",
reply "yes" to the question "Are you submitting to a special issue?"
and then select "Nonlocal Codes" among the options.
