Subject: MJD Powell

I am very sad to let the NA-net community know that M.J.D. Powell
passed away this morning, 19th April 2015.

Many of the NA community would have known Mike Powell as one of the
giants of the Golden Age of numerical analysis and the pioneer of
optimization. Indeed, he has been honoured for his achievements, not
least by being elected a Fellow of the Royal Society and a Foreign
Member of (American) National Academy of Sciences and of Australian
Academy of Sciences, but also by the inaugural Dantzig Prize of
Mathematical Programming Society, Naylor and Senior Whitehead Prizes
of London Mathematical Society, Gold Medal of Institute for
Mathematics and its Applications... The list goes on and on. For his
many friends, though, he was not just a brilliant mathematician but
also a lovely person of total integrity and honesty, a role model in
mathematics, a dear friend and a teacher to many. He will be sorely

Subject: Wanted: Computational Case Studies

Computing in Science and Engineering (CiSE), a bi-monthly publication
of the IEEE Computer Society and the American Institute of Physics,
runs a column called "Your Homework Assignment," which we edit.

The idea is to present case studies that illustrate important issues
in computation and that provide exercises so that students have
motivation and guidance for solidifying their computational skills.

Some of the case studies were collected in the textbook Scientific
Computing with Case Studies, SIAM, 2009:

Others are NASA Computational Case Studies:

We invite you to use these case studies in your teaching.

And we especially invite you to contribute new case studies for
publication in CiSE:

Please contact us if you are interested.

Subject: BBComp: Black-Box Optimization Competition, IEEE-CEC'2015

We propose the first black box optimization competition in the
continuous domain where test problems are truly black boxes to
participants. The only information known to the optimizer/participant
is the dimension of the problem, bounds on all variables, and a budget
of black box queries. The competition aims at attacking a growing
impact of over-fitting of optimization algorithms to a narrow set of
existing benchmark problems.

All the material including the source code in C/C++, MATLAB, Python
and Java is available at

Deadline: April 30, 2015

The results of the competition will be announced during the CEC'2015
on May 25-28, 2015, Sendai, Japan. Participants do not need to attend
the conference or submit papers, they can choose to be anonymous to
the other participants. A modest cash prize of 500 EUR in total is
allocated to the best 3 algorithms.

Subject: Cell Mechanics, Morphogenetics and Pattern Formation, UK, Sep 2015

Cell Mechanics, Morphogenetics and Pattern Formation: perspectives
from the experimental and theoretical points of view (CGPW02)

Dates: 14th September 2015 to 18th September 2015

Location: Isaac Newton Institute for Mathematical Sciences, University
of Cambridge, UK.

The mechanical characterisation of individual cells is complex and
dynamic. Nonetheless, great progress has been made in understanding
how the dynamics of subcellular structures leads to cell shape and
motility. Static tissues have also been well characterised. It is at
the level of morphogenesis where the bridging of scales between
individual cell dynamics and tissue dynamics is least understood.
This workshop aims to (1) present a framework for understanding what
is already known about cell-level and tissue-level mechanics, (2)
identify gaps in our understanding of how cells interact mechanically
in tissues in order to actuate morphogenesis, (3) propose new
collaborations to increase our understanding of the cell-tissue
emergent dynamics. We will bring together experts in development,
microscopy, image analysis, biomechanics, and modeling.

Deadline for applications: 12 July 2015

competing sessions.

New Mathematical and Computational Problems involved in Cell Motility,
Morphogenesis and Pattern Formation (CGPW04)

Dates: 7th December 2015 to 11th December 2015

Location: Isaac Newton Institute for Mathematical Sciences, University
of Cambridge, UK.

Cell motility, morphogenesis, and pattern formation are essential
features of cell dynamics. The involved biochemical processes and
biomechanical properties range from the intracellular level over cell
surface dynamics, cell-cell and cell-tissue interactions up to the
scale of cell population behaviour influencing organ formation and

The aim of this workshop is to bring together scientists working on
these timely and challenging topics of mathematical biology, analysis
and numerics. It will provide both an international framework and
motivation to further develop the modelling of the mentioned
biological phenomena and to strengthen the synergies between the
involved branches of applied mathematics, but also between mathematics
and life sciences.

Subject: Research Chair Position, Institute for Mathematical Sciences, Ghana

The Alexander von Humboldt Foundation is calling for applications for
a German Research Chair for Mathematics and its Applications at the
African Institute for Mathematical Sciences in Ghana (AIMS Ghana). In
the coming years, this endowed chair will promote higher education and
research in mathematics in Africa.

This call is aimed at postdoctoral academics from any country who
demonstrably conduct application-related research in the field of
mathematics, have several years' experience in training students and,
ideally, doctoral candidates. Experience in working in and cooperating
with Africa and a willingness to collaborate with other academic
disciplines are also desired.

The closing date for applications is 15 July 2015. The application
must be supported by at least one collaborative partner in Germany.
This research chair is funded with a total of 560,000 Euros for a
four-year period. A concurrent appointment at a collaborating
university in Ghana is planned.

AIMS Ghana is part of the AIMS Next Einstein Initiative which seeks to
establish a coordinated network of 15 supra-regional centres of
excellence in mathematics across Africa by the year 2020. The endowed
research chair, which is being advertised internationally, is designed
to help promote networking between AIMS Ghana and German universities
and to drive networking amongst the various AIMS centres in Africa. As
part of the German Research Chair programme that is financed by the
Federal Ministry of Education and Research, the Humboldt Foundation
will fill three further research chairs at AIMS centres in South
Africa, Cameroon and Tanzania in the coming years.
