**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-

lite).

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**

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

investigations.

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.

PREFACE

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

http://www.vsppub.com.
