Dates for the Applied Nonlinear Mathematics Initiative

There will be two rounds of invitations to submit applications for funding for the ANM initiative of EPSRC in the next year. Closing dates will be 24/11/95 and 24/03/96. Look out for further details from EPSRC in late September.

Live Solitons

On Wednesday 12 July 1995, an international gathering of scientists witnessed a re-creation of the famous canal sighting of the soliton or solitary wave first seen in August 1834. They were attending a conference on nonlinear coherent structures in physics and biology at Heriot-Watt University, Edinburgh, organised by Chris Eilbeck and Dugald Duncan of the Department of Mathematics.

The occasion also marked the naming of a new aqueduct after John Scott Russell, the Scottish scientist who made the original observation. the aqueduct carries the Union Canal over the Edinburgh City Bypass. The naming ceremony was carried out by Professor Alwyn Scott of Tucson and Lyngby.

A brief report including a colour photograph appeared in the Aug 3 issue of Nature (v. 376, pg 373, 1995).

Details of the meeting (including electronic proceedings) and of the soliton re-creation (including a video) can be found on WWW at http://www.ma.hw.ac.uk/solitons/.

Nonlinear Response and Respiratory Diagnosis: New Email Group

fot-group is a new email group, set up to discuss the investigation of respiratory physiology through its response to externally applied oscillatory stimulation. Any reader interested in applying their ideas and experience to this field is warmly invited to join.

The application of a variety of acoustic waves at the mouth (the "Forced Oscillation Technique") enables the mechanical impedance, Zrs, to be computed in the time and frequency domains. This can be useful in characterising asthma and chronic bronchitis: as the measurements are easy to make, they are very valuable in paediatrics or adult clinical cases where normal lung function measurements (eg: spirometry) can be impossible or unreliable. The impedance Zrs can be modelled in terms of network behaviour and becomes quite non-linear during breathing or in respiratory diseased states.

Currently the group has 27 members in 7 countries and is quite active.

To join, send an email to mailbase@mailbase.ac.uk with the sole text:
join fot-group@mailbase.ac.uk firstname lastname
and you should receive a number of introductory messages in return.
If you do join, please also mail a one screen introduction to the group about your background.

The group's address is:
fot-group@mailbase.ac.uk
(NB mail sent to this address goes to _all_ members)
