NEW Institute for Advanced Study

The Institute for Advanced Study has announced that it will begin a new program in theoretical biology, to be headed by Martin Nowak, one of the world's leading researchers in this area. Nowak,  presently professor of mathematical biology at Oxford University and head of the Mathematical Biology Group will move to the Institute this Winter to lead the research initiative. The use of mathematical ideas, models, and techniques in the biosciences has been growing rapidly and becoming increasingly important. Although mathematical biology began in the 1920s with the work of Fischer, Haldane and Wright in genetics, Lokta and Volterra in ecology, and Kermack and McKendrick in epidemiology, biology does not have the same mathematical/theoretical tradition as the physical sciences. However, several areas of biology have gradually developed an understanding of the importance that mathematical approaches can play.

"The Institute's new initiative is a tremendous opportunity for theoretical biology and an important recognition of the whole field", Nowak commented. "The main objectives of the new program will be to undertake world-class research in diverse areas of mathematical biology, ranging from evolutionary biology and ecology to infectious diseases of humans. The emphasis will be on maintaining research collaborations with leading experimental groups, as mathematical theory in biology is usually at is best when in close conjunction with experimental data."

New Recurrence Analysis software

Version 2.5 of the VRA (Visual Recurrence Analysis) software for Windows 95 has recently been released. VRA is a software package which is used to display and study recurrence plots, first described by J.P. Eckmann, S. Oliffson Kamphorst and D. Ruelle in "Recurrence plots of dynamical systems" in 1987. Recurrence plots are a relatively new graphical device for the qualitative assessment of time series. With recurrence plots the user can graphically detect hidden patterns and structural changes in data or see similarities in patterns across the time series under study. Recurrence plots are essentially a graphical representation of the correlation integral in such a way so that the time dependence in the system under study is preserved. They are constructed by embedding a one-dimensional signal into a higher-dimensional space, calculating the distances between all vectors and color-coding these distances on the time-ordered matrix. VRA version 2.5 is free for copying and distribution. It can be downloaded from http://www.netcom.com/~eugenek/page6.html .Some sample data files are included, as well as the help file.

EMC established at Heriot-Watt University

The Edinburgh Multidisciplinary Consortium for Advanced Data Analysis of Complex Systems (EMC) has been established in the Physics Department  at Heriot-Watt University. It interfaces academics with doctors and  financiers to undertake fundamental and strategic research into  modelling, simulation and prediction of real-life complex systems. It aims to develop new strategies and methodology to improve the  diagnosis and treatment of cardiac arrest patients and to advance the analysis and prediction of financial markets.

The Consortium is led by Professor R.G. Harrison in the Physics Department and is funded by the Scottish Higher Education Funding Council (SHEFC) Research Development Grant. The four partners involved are:

1) Physics Department at Heriot-Watt University
2) Accident & Emergency Department, The Royal Infirmary of Edinburgh
3) Laerdal Medical Ltd, Kent
4) Investment Division, Standard Life, Edinburgh

Info Dynamics Days 1999/2000

The Dynamics Days/Europe solicits proposals for the venue of the 1999 and 2000 Dynamics Days conferences. Potential hosts for Dynamic Days are urged to submit a proposal well ahead of the meeting, as well as proceeding with grant applications so the scheduling decisions can be made in time.  The next open date is early summer 1999, and the committee expects to select the 1999 location by the middle of September 1998. The committee favours locations with inexpensive housing to encourage younger  participants and good financial support for those who could not participate otherwise. The proposal should include a reasonably reliable forecast of such funding; proposals that would support a series of Dynamics Days conferences would be especially welcome.

Pre-proposals (in e-mail form) can be communicated to any of the members of the Dynamics Days/Europe ad-hoc advisory committee

The format of Dynamical Days Meetings

Typical Dynamical Days have had between 120 and 300 participants. The date is open (usually summer), so as to avoid conflicting with the US Dynamics Days. The organisers should cover travel and lodging for 12-18 invited speakers, and obtain some extra funding to encourage participation from junior researchers and researchers from central/eastern Europe. No funding is available from the Dynamical Days committee.

Help on unemployment projections

I am currently doing research in the area of economics, although I am an Employment Counselor and writer on areas of work. I am looking for resource material (primary & secondary) on statistics and unemployment projections. The Canadian government has based much of its policy on linear analysis and things are not going well in terms of predictability. Is there any work on non-linear approaches to this area?

Help on literacy acquisition

I am preparing a PhD thesis examining literacy acquisition through the 'eyes' of non linear theory. The starting point is Paul Van Geert's work on language development. If anyone has any interesting references or sources, I would love to hear from you! I am an educational psychologist by profession and have good access to psychological material.
