Subject: New preCICE Release v2.1

The new version comes with significantly improved error messages, an
alternative RBF mapping implementation based on Eigen,
nearest-projection mapping with quads, and many more smaller additions
and bugfixes.  For more information please have a look at our blog post:
https://precice.discourse.group/t/highlights-of-the-new-precice-release-v2-1/274

What is preCICE? preCICE is a coupling library for partitioned
multi-physics simulations, including, but not restricted to
fluid-structure interaction and conjugate heat transfer
simulations. The software offers methods for transient equation
coupling, communication, and data mapping. preCICE is written in C++
and offers additional bindings for C, Fortran, Matlab, and
Python. Ready-to-use adapters for many solvers, such as OpenFOAM,
deal.II, FEniCS, SU2, or CalculiX, are available. Due to the
minimally-invasive approach of preCICE, adapters for in-house codes
can be implemented and validated in only a few weeks. preCICE is an
open-source software under the LGPL3 license.

Subject: Software Release, pyMOR 2020.1

The pyMOR development team is happy to announce the release of version
2020.1 of pyMOR (www.pymor.org).

pyMOR is a software library for building model order reduction
applications with the Python programming language. Implemented
algorithms include reduced basis methods for parametric linear and
non-linear problems, as well as system-theoretic methods such as
balanced truncation or IRKA. All algorithms in pyMOR are formulated in
terms of abstract interfaces for seamless integration with external
PDE solver packages. Moreover, pure Python implementations of finite
element and finite volume discretizations using the NumPy/SciPy
scientific computing stack are provided for getting started quickly.

Highlights of this release are support for non-intrusive model order
reduction using artificial neural networks, the subspace accelerated
dominant pole algorithm (SAMDP) and the implicitly restarted Arnoldi
method for eigenvalue computation. Parameter handling in pyMOR has
been simplified, and a new series of hands-on tutorials helps getting
started using pyMOR more easily.

Tuesday, 11th August.  This high-profile event features nine plenary
addresses and ten discipline-specific sessions, including one on
mathematical modelling and analysis in the life sciences, August 3-5
(depending on time zone):

Plenary speaker: Yihong Du, University of New England

Session speakers:
- Chiun-Chuan Chen, National Taiwan University, Taiwan
- Yong-Jung Kim, KAIST, Korea
- Yoichiro Mori, University of Pennsylvania, USA
- Yoshihisa Morita, Ryukoku University, Japan

Subject: Imaging meets Computational PDEs, ONLINE, Sep 2020

The registration for the LMS-workshop on "Imaging meets Computational
PDEs", 17 September 2020,
https://sites.google.com/view/imaging-pde-2020,
is now open (deadline 14 September 2020).

Registration is free of charge. The event will be held on Zoom,
details to join the event will be communicated after registration.

Confirmed speakers: Andrea Cangiani (Nottingham, UK); Teo Deveney
(Bath, UK); Hanne Kekkonen (Delft, Netherlands); Tobias Kluth (Bremen,
Germany); Malena Landman (Bath, UK)

Scope: Imaging and PDE-based numerical modeling are fascinating
mathematical research fields and play an important role in numerous
medical diagnosis tools. To mention a few examples, they lie at the
core of electrical impedance tomography and computed tomography.
Although there is a natural overlap between these disciplines, there
has been little effort to connect the two research communities, who
often ended up working on parallel research agenda. The goal of this
event is to give researchers from these communities an opportunity to
gather, exchange research ideas, and design joint research plans. A
closer collaboration would allow both research communities to widen
their research perspective, and to develop together a new vision with
solid theoretical foundations and robust numerical algorithms.

Subject: Postdoc Position, Randomized NA, NC State Univ

The Department of Mathematics at NC State University has an open
postdoctoral position under its NSF funded Research Training Group
RTG, DMS-1745654 in Randomized Numerical Analysis
(https://wp.math.ncsu.edu/rna/). The position is restricted to US
citizens, nationals, and permanent residents. The postdoctoral
associate must hold a PhD in mathematics or a closely related
discipline awarded after January 1, 2020, and the applicant should not
have any prior postdoc appointments. An exception to this rule,
occasioned for instance by a career interruption, may be requested in
the cover letter.  The postdoctoral associate is expected to engage in
research related to at least one of the three complementary research
thrusts of the project in randomized numerical linear algebra, random
nonlinear solvers, and global sensitivity analysis. Based on
background, strengths, and interests, the postdoc will be assigned one
research mentor from the faculty associated with the RTG: Alen
Alexanderian, Mohammad Farazmand, Pierre Gremaud, Ilse Ipsen, Tim
Kelley, Arvind Saibaba, and Ralph Smith. An academic mentor will be
chosen from this group to oversee the postdoc's training and
professional development. The postdoc will also play a leading role in
mentoring students associated with some of the project's working
groups; the postdoc will be expected to assist in organizing seminars
and activities related to the general research of the RTG. In
addition, the postdoc will teach, on average, one course per semester
in the Department of Mathematics.  Inclusiveness and diversity are
critical to the success of the College of Sciences and the University.
The selected candidate will be expected to foster an environment that
is supportive and welcoming to all groups.  This position is for a
term of up to three years, contingent upon performance. The starting
date is anticipated between January and August 2021. The 11-month
salary of $62,500 includes summer support.  In addition, the postdoc
will be given an annual travel budget of $3,000.

Through the mathjobs.org system
(https://www.mathjobs.org/jobs/list/14743), applicants should submit a
cover letter, a CV, a research statement, and the names of at least
three potential letter writers. Women and members of underrepresented
minority groups are particularly encouraged to apply.  Applications
will be evaluated on a rolling basis until the position is filled;
please apply as soon as possible. Inquiries may be directed to Pierre
Gremaud (RTG Director): [log in to unmask] The deadline for full
consideration is December 1, 2020, although later applications will be

Subject: Postdoc Position, Randomized Numerical Linear Algebra, UT-Austin

Applications are invited for a postdoctoral research position in the
Oden Institute for Computational Engineering and Sciences at the
University of Texas at Austin, in the research groups of Gunnar
Martinsson and Rachel Ward.

The new position will form an important component of an NSF funded
Focused Research Group targeted at developing randomized algorithms
for solving linear systems of equations, and related questions within
linear algebra and optimization. In addition to the group at
UT-Austin, the project also involves coordinated efforts at Yale and
Caltech.

The position is available immediately. However, the start date is
flexible and the position will remain open until filled.

The initial appointment is for one year, with the possibility of
renewal based upon availability of funding and performance. The
appointment can be renewed up to 4 times, but an overall duration of 2
or 3 years would normally be expected.
