Subject: Janusz Kowalik, February 28, 1934 - November 3, 2022

Janusz Kowalik passed from this world on November 3, 2022 in hospice
care in Kirkland, Washington after a prolonged battle with chronic
heart and kidney disease.

Janusz was born on February 28, 1934 in Krzemieniec, then part of
Poland. He grew up during World War II. He attended Gdansk Polytechnic
where he met his future wife Krystyna in 1954 and completed his
Master's Degree in Naval Architecture in 1956. Janusz and Krystyna
were married in Warsaw in 1959. Subsequently, he completed his PhD in
Applied Physics in 1961.

Janusz worked at Boeing in Seattle, Washington until 1974 when he
moved to Montreal for a year. He then settled in Pullman, Washington
in 1976 where he was head of the academic computing center until
1984. Janusz then lived in Bothell for 38 years until his
death. During this time, Janusz worked in the advanced technology
division in Boeing and also lectured at the University of
Washington. He retired in 2002 and engaged in a series of
international collaborations with other scientists and continued
authoring and editing books.

A lifelong athlete, Janusz enjoyed running, swimming, weight lifting,
and skiing. He participated in many other sports including
windsurfing, tennis, and scuba diving. He achieved multiple
Presidential Fitness awards throughout his life and meticulously
tracked his progress and achievements. At the age of 60 he began
studying karate and earned his black belt in 2006. The strength
developed through years of physical exercise fortified him for the
physical challenges he confronted in the last years of his life.

Janusz was a prolific author, editor, and lecturer. As he began his
transition from this world, he expressed gratitude for everything he'd
achieved in life, for his family, and the legacy he left behind. He
achieved everything he set out to do and lived his life to the
absolute maximum. He left only once his body could no longer carry

Janusz is survived by Krystyna, his wife of 63 years; his son Olaf and
his wife Lisa; his grandson Alex; his nephew Piotr Maszkiewicz and his
wife and children; and his cousin Marek Laszkowski.

Subject: New Book, The Theory of Composites

The Theory of Composites by Graeme W. Milton

Composites have been studied for more than 150 years, and interest in
their properties has been growing. The Theory of Composites is a
classic volume, providing the foundations for understanding a broad
range of composite properties. These properties can be explored either
through the model geometries or through microstructure-independent
bounds, obtained through variational principles, analytic methods, and
Hilbert space approaches. Most interesting is when the properties of
the composite are unlike those of the constituent materials, and there
has been an explosion of interest in such composites, now known as

Subject: New Book, The Zen of Exotic Computing

The Zen of Exotic Computing by Peter M. Kogge

This textbook explores an important subset of alternatives to the
Turing/von Neumann model of computing. The models are organized into
distinct groups. After a review of the Turing/von Neumann model to set
the stage, the author discusses those that have their roots in the
Turing/von Neumann model but perform potentially large numbers of
computations in parallel; models that do away with the preplanned
nature of the classical model and compute from just a statement of the
problem; others that are simply mathematically different, such as
probabilistic and reversible computation; models based on physical
phenomena such as neurons; and finally those that leverage unique
physical phenomena directly, such as quantum, optical, and DNA-based

Subject: Nonlinear Model Reduction for Control, USA, May 2023

We would like to invite you to participate in the "Conference and
workshop: Nonlinear model reduction for control" in Blacksburg, VA,
May 22-26, 2023. A tutorial-style workshop for junior researchers will
be held on Monday and Tuesday (22-23) followed by a 3-day conference
with state-of-the-art research talks. For more information, visit

The objectives of the conference will be to bring together leading
experts in nonlinear model reduction, control and tensor-based
computations to learn and advance the state-of-the-art and identify
challenges and opportunities in the field. The conference themes
revolve around nonlinear balanced truncation, Hamilton-Jacobi-Bellman
approaches to control and model reduction, interpolatory and data-
driven methods for nonlinear systems, proper orthogonal decomposition
for control, and tensor methods for scalable computation.

The deadline to submit abstracts for posters and contributed talks is
extended through January 31, 2023. Please fill out the form at to indicate your participation,
apply to be considered for partial travel support, as well as to
optionally submit a title and abstract of a talk for the conference
portion of our workshop.

A limited number of travel awards will be offered to early career
researchers through an NSF-CMMI grant and a decision about support
will be made in early February. A registration fee of $300 is required
for participation for participants that do not get NSF travel support.

Subject: Biennial NA Conference, UK, Jun 2023

It is our pleasure to announce that registration is now open for the
29th Biennial Conference on Numerical Analysis, to take place during
27-30 June 2023 at the University of Strathclyde, Glasgow,
Scotland. This long established conference is open to all researchers
in the field, and you are invited to contribute a talk on your current
work. PhD students and young researchers will find the environment
particularly welcoming.

We also welcome proposals for minisymposia for the conference. A
minisymposium should consist of a multiple of 3 speakers (up to 12).
To propose a minisymposium send a title, a short abstract and a list
of speakers to, or directly to one of the
conference organisers.

Subject: Postdoc Position, Computer Science, Wake Forest Univ

The Department of Computer Science at Wake Forest University invites
applications for a postdoctoral research fellowship beginning in July
2023. The candidate will work primarily with Dr. Grey Ballard and
Dr. Aditya Devarakonda to design, implement, and analyze
high-performance algorithms for sparse matrix and tensor
computations. We are particularly interested in scholars who have a
strong background in numerical linear algebra, numerical analysis,
and/or parallel and high-performance computing. In addition to
conducting research, the fellow will have the opportunity to teach at
the undergraduate level if mutually agreeable. This is a one-year
contract position with possible extensions.

The fellow will be part of Sparsitute: A Mathematical Institute for
Sparse Computations in Science and Engineering. Sparsitute is
supported for 5 years by the Department of Energy and is a
collaboration between LBNL, ORNL, Purdue University, University of
