Subject: Algorithms for Macromolecular Modeling
Algorithms for Macromolecular Modeling
an interdisciplinary workshop
September 30--October 2, 1994
Kansas Institute for Theoretical and Computational Science
University of Kansas at Lawrence
This is a special workshop on algorithms and parallel implementations for
macromolecular dynamics, protein folding, and structure refinement, including
the treatment of quantum effects. The emphasis is on the numerical and
algorithmic challenges to achieving dramatic gains in the performance of
software for the simulation of proteins, nucleic acids and other polymers.
Topics appropriate to the workshop include (but are not limited to) the fast
multipole method for the N-body problem, implicit discretizations and multiple
time-stepping, constrained dynamics, energy minimization techniques (including
global methods), locally enhanced sampling techniques, parallel computing
schemes for biomolecules, building quantum mechanical effects into molecular
dynamics, and continuum solvation models in molecular dynamics simulations.
The workshop will take place Friday--Sunday on the campus of the University
of Kansas with support from the National Science Foundation, the DOE Office
of Scientific Computing and the Kansas Insitute for Theoretical and
Computational Science (KITCS), an interdisciplinary NSF-funded research
institute. There will be a registration fee of $100.
The format will include a mix of 25 and 40 minute talks. A partial list of
speakers includes Paul Bash (Argonne), John Board (Duke), David Chandler
(Columbia), Ron Elber (UI-Chicago/Hebrew U.), Barry Honig (Columbia),
Peter Kollman (UCSF), Zan Luthey-Schulten (UI-Urbana-Champaign),
Montgomery Pettitt (Houston), Carol Post (Purdue), Tamar Schlick (NYU),
Klaus Schulten (UI-Urbana-Champaign), Ridgway Scott (Houston), and
Peter Wolynes (UI-Urbana-Champaign).
The workshop is being organized by Jan Hermans (UNC), Krzysztof Kuczera (KU),
Ben Leimkuhler (KU) and Robert Skeel (UIUC). Space is limited. Some funds
are available to assist with expenses. Recent PhDs, women, and members of
under-represented minorities are particularly encouraged to apply. Address
any inquiries either directly to the organizers or to KITCS at the address
given below.

Subject: Position at Paul Sabatier University
VACANT POSITION AT THE PAUL SABATIER UNIVERSITY, TOULOUSE, FRANCE.
Very likely a position of Applied Mathematics (a permanent position, more or
less equivalent to Associated Professor) will be vacant at the Paul Sabatier
university on October 1995 ; this vacancy is due to a retirement.
We would like to hire a mathematician whose main interests in research are on
APPROXIMATION or OPTIMIZATION, or both (in the broad sense of the words).
Evidently the applicants should be able to deliver talks and teach in French.
It is desirable for us to get detailed curriculum vitae and curriculum
studiorum of possible applicants before 15 September 1994.Please send them to:
J.-P. DEDIEU
Laboratoire Approximation et Optimisation
Departement de Mathematiques
Universite Paul sabatier
118, route de Narbonne
31062 TOULOUSE, France.
e-mail : dedieu@cict.fr
For all applicants, especially for foreign ones, we recall that the so-called
"qualification" is necessary to get a permanent position in France. The
qualification is delivered in spring by a national committee, on the basis of
research achievements and teaching experience, and remains valid for 4 years.
The first step of the qualification procedure must be carried out on October
1994, from any capital-town in france ; the final decision for the next
session will be taken in spring 1995.The final announcement of vacancies of
positions of professors in French universities will me made around April 1995.

Subject: Post Doc Position at Bath, UK
Post Doctoral Research Officer
School of Mathematical Sciences
University of Bath, UK
Applications are invited for a 3-year postdoctoral Research Position funded
by the UK EPSRC in the Schools of Mathematical Sciences and Chemical
Engineering at the University of Bath, UK. The start date is 1st October,
or as soon as possible thereafter.
The project is concerned with the numerical solution of systems of differential-
algebraic equations and integral equations that arise in modelling catalytic
combustion in monolith reactors. The work will involve (a) theoretical
numerical analysis, (b) consequent development of efficient and reliable
numerical methods, and (c) testing the methods on equations which arise in
real applications.
Applicants should be experienced in some aspect of numerical analysis, be
competent programmers, and be interested in real problems. A willingness to
learn about concepts in catalytic combustion would be an advantage.
Please contact Professor A. Spence (na.spence@na-net.ornl.gov or
as@maths.bath.ac.uk) for further details as soon as possible.
