Subject: TfMin Orbit Package

We are pleased to announce TfMin, a Fortran and Matlab package
designed for the numerical solution of continuous 3D minimum time
orbit transfer around the Earth, especially for low thrust
engines (e.g., thrust of 0.14 Newton for a 1500 Kilogramme satel-

The numerical method used is single shooting which is coded in
Fortran 77 and can be used on general optimal control problems.
It automatically generates the associated boundary value problem
thanks to Automatic Differentiation.

A specific Matlab interface is provided. It allows the user to
set the parameters of the min time transfer problem and to draw
the orbits computed. Results of [1] can be obtained in this way,
in the spirit of reproducible research.

Subject: Special Issue, Linear Algebra and its Applications

Special issue on Matrices and Mathematical Biology

Call for papers

In the last decade the field of mathematical biology has expanded very
rapidly. Biological research furnishes both data on and insight into the
workings of biological systems. However, qualitative and quantitative
modelling and simulation are still far from allowing current knowledge to
be organized into a well-understood structure. Further, the diversity
present in mathematical biology, coupled with the absence of a single
unifying approach, has inspired the formation of entirely new scientific
disciplines such as bioinformatics.

Theoretical research activity in mathematical biology is
naturally of an interdisciplinary character. It involves
mathematical and statistical investigations, sometimes in
combination with techniques originating from the computational
sciences. In many of these approaches, linear algebra is key to
solving the mathematical problems which arise. For instance, in
some population models, the asymptotic rate of increase of the
population turns out to be the spectral radius of a certain
matrix associated with the population, while the other
eigenvalues also yield information on the evolution of the
population's structure. Conversely, problems in mathematical
biology can enrich linear algebra. For example, in attempting to
measure the influence of a single matrix entry on a simple
eigenvalue, linear algebraists frequently employ the derivative
of that eigenvalue with respect to the entry. However, some
biologists have proposed the use of the elasticity, or a
logarithmic derivative, of an eigenvalue with respect to a matrix
entry in order to measure the effect on that eigenvalue of
perturbing a matrix entry. Thus linear algebraists are challenged
to deepen and develop the understanding of the ways in which the
effects of changes in the ecological conditions on the
populations can be measured through further theoretical

A recent book by Caswell on matrix population models makes extensive use
of linear algebraic techniques. Quoting from the introduction to that
book: "Matrix population models -- carefully constructed, correctly
analyzed, and properly interpreted - provide a theoretical basis for
population models... A goal of this book is to raise the bar of what
constitutes rigorous analysis in population models.... The work of the
population biologist is too important to settle for less." But Caswell's
call for careful mathematical construction and analysis applies to areas
beyond the subject of population models; clearly a rigorous approach would
benefit all areas of interaction between biology and mathematics.

The Special Issue of LAA dedicated to Matrices and Mathematical Biology is
intended to both foster and accelerate cross fertilization between those
working primarily in linear algebra and those working primarily in
mathematical biology. The editors hope that such an issue of LAA will be
of benefit to both fields.

This special issue will be open for all submissions containing new and
meaningful results that advance interaction between linear algebra and
mathematical biology. The editors welcome submissions in which linear
algebraic methods play an important role for novel approaches to problems
arising in mathematical biology, or in which investigations in
mathematical biology motivate new tools and problems in linear algebra.
Survey papers which discuss specific areas involving the interaction
between biology and linear algebra, particularly where such interaction
has been successful, are also very welcome.

Areas and topics of interest for the special issue include, but are not
limited to:

metabolistic pathways
statistical data analysis
linear algebra problems in graph partitioning
matrix population models
model discrimination in biokinetics
linear algebra problems in network analysis and synchronization
subspace oriented eigenvalue problems
aggregation/disaggregation or related techniques
hidden Markov models
epidemic models
modelling phylogenetic trees

All papers submitted must meet the publication standards of Linear Algebra
and its Applications and will be refereed in the usual way. They should be
submitted to one of the special editors of this issue listed below by 31
May 2003.

Beginning with this volume the name of the journal will change
from East-West Journal of Numerical Mathematics
to Journal of Numerical Mathematics.

After the change of the political system in Eastern Europe,
the former name of the journal was chosen to highlight the
necessity to provide a platform for an exchange of ideas and
results in numerical mathematics between researchers in Eastern
and Western countries. Looking at the contents of the first nine
volumes, we believe that the journal has perfectly achieved this
goal. Now, roughly ten years after, the former name is considered
as being no longer appropriate and even rather misleading.

The change in the name, however, will have no impact on the
scientific aims and scopes of the journal.

In order to ease the burden of the Managing Editor, beginning
with Volume 10, No.1, two Editors-in-Chief will take care of
the editing process, namely, Yuri A. Kuznetsov (Houston, USA)
and Ronald H.W. Hoppe (Augsburg, Germany). Moreover, three new
members have been appointed to the Editorial Board. These are
C. Carstensen (Vienna, Austria), Z. Chen (Dallas, USA), and
E. Tyrtyshnikov (Moscow, Russia).

As far as the submission of papers is concerned, authors may
submit manuscripts either directly to the Editors-in-chief or
to any member of the Editorial Board. As before, the members
of the Editorial Board may communicate or submit manuscripts.
All manuscripts will be subject to a reviewing process done by
the members of the Editorial Board and external reviewers.
Guidelines for the preparation of manuscripts including a
style file can be found on the Web-page of the journal on
