Subject: Vera Kublanovskaya

With deep regret we inform that Vera N. Kublanovskaya has died
yesterday, 22nd February 2012, on her 92nd year of life. This happened
in Saint-Petersburg, where she worked and lived all her life. Remember
she is one of the authors of the QR algorithm, one of most famous
algorithms of numerical linear algebra. Good and grateful memory of
her will live forever with us.

Subject: Cholesky's method

Dear colleagues,

I am trying to retrieve the earliest books where Cholesky's method for
solving symmetric positive definite systems of linear equations is

I already found the books by Hartree (1952), Salvadori (1952), Booth
(1955), Bodewig (1956),...

If you know older books, or other books published in these years, could
you please send me the exact reference.

Thank you and best regards,

Claude Brezinski

Subject: OpenLB New Release 0.7 and LBM Forum Available

The OpenLB developer team is happy to announce that a new release of
our open source Lattice Boltzmann code is available for download on
the project website .

New Release 0.7 Available: A new module allows to analyze the
performance of computations and runtime estimations
(cf. "examples/cavity2d"). The console output is standardized
including sequential and parallel output. Further, a rewritten unit
converter enables direct conversion between physical and internal
lattice units. The usage of the XML interface is simplified by direct
class constructions from XML parameter files, illustrated in
"examples/cavity2d". This example includes also a description file for
OpenGPI (, which provides a graphical user
interface. Finally, the CVMLCPP-library has been updated to ensure
compatibility with gcc-4.6.

Forum on LBM and OpenLB Added: With the intention to allow discussions
on OpenLB and Lattice Boltzmann Methods in general a new forum has
been added to the OpenLB-website. Furthermore, a section concerning
upcoming conferences and workshops on LBM has been included. This
allows organizers to promote their events by informing the community
e.g. by a short descriptions and links.

Please consider to contribute code or join the developer team yourself
to strengthen the LB community by sharing your findings in an open and
easy reproducible way.

Subject: 9th IMA Maths in Signal Processing, UK, Dec 2012

Ninth International Conference on Mathematics in Signal Processing
17 – 20 December 2012, Austin Court, Birmingham, UK

Signal processing constitutes an important area for the application of
mathematical concepts and techniques fuelled, for example, by
developments in mobile communications, multimedia systems and digital
TV. The subject is still advancing rapidly in areas such as
non-linear/non-Gaussian/non- stationary signal processing, compressive
sampling, digital communication systems, iterative estimation
(e.g. turbo codes), blind deconvolution/signal separation, broadband
systems, compressive sensing and novel sampling schemes. The last IMA
conference on this subject was held in December 2008 and in response
to popular demand, the next one will be held in December 2012. The aim
of the conference is to bring together mathematicians, statisticians
and engineers with a view to exploring recent developments and
identifying fruitful avenues for further research. It is hoped that
the meeting will help to attract more mathematicians into this
important and challenging field.

The conference will follow the same successful format as before,
comprising tutorials, keynote addresses and six non-overlapping
sessions each featuring:
(a) two or three spoken papers with some tutorial content
(b) a related poster session for more specific research papers.

A social programme will be organised and will include a reception to
welcome delegates.

We are looking for an enthusiastic doctorate to work in
interdisciplinary projects aimed at (1) developing novel
stochastic/multiscaled simulation algorithms and, by combining
modelling and experimental techniques, (2) to reach a better
understanding of epigenetic changes, eukaryotic gene expression, and
effects of stochasticity in key cell signal transduction
processes. The ideal candidates should have a strong background in
Applied Mathematics, Control Engineering and/or Computer Science, as
well as a strong interest to collaborate with experimental
biologists. Previous experience with dynamical systems (ODEs, PDEs),

Specific projects will entail constant feedback and cooperation with
experimental and theoretical groups. Thus, the postdoc is expected to
travel, work in groups, have excellent personal and communication
skills, and a willingness to communicate research results to
interdisciplinary audiences.

The successful candidate will join the Integrative Systems Biology
Unit of the Okinawa Institute of Science and Technology Graduate
University, and will work under the supervision of Assistant Professor
