Subject: Possible NA Conference with STOC 97
CONFERENCES BACK-TO-BACK WITH STOC'97: IS ANYONE INTERESTED?
We have been recently informed that El Paso was officially selected as a
site for 1997 ACM STOC (Symposium on Theory of Computing, May 4-7, chairman
of the local organizing committee Luc Longpre, firstname.lastname@example.org).
STOC is the largest ACM symposium, that attracts lots of researchers
in all areas of theory. Several times, it has been organized
back-to-back with other ACM and other conferences that are
thematically similar. Having several conferences at one place enables
researchers and students to visit several at the time with a reduction
in total cost, and thus increases the attendance of all conferences.
Having several conferences at the same place also makes the job of
local organizers easier.
In view of that, I have the following proposal to NA community.
As the latest STOC conferences show (in particular, STOC'95 that
was held this May in Las Vegas), there is a growing interest in
theoretical aspects of computations with real numbers: algorithms,
computational complexity, different computational models.
Therefore, I think that it may be beneficial to organize
NA-oriented conference(s) and/or workshop(s) back-to-back with STOC.
STOC will be held in the hotel Camino Real Paso del Norte (the best
hotel in town). They give special rate of $60-80$ for the conferences.
As of now, they have space available unitl May 23, 1997, but the space
fills fast, so if anyone is interested, we need to act fast.
El Paso is right on the border with Mexico, and my experience of
organizing the International Workshop on Applications of Interval
Computations here in El Paso this February shows that this city and
especially its surrounding sites are a tourist attraction.
Due to my specific interests, one possibility would be to have another
Interval Computations conference; however, interval community may
prefer some yet unvisited site, so it may be possible to have a
broader (or somewhat different) meeting(s) instead.
I would greatly appreciate any suggestions and/or names of people who may be

CALL FOR PAPERS
Readers of this newsletter are encouraged to submit their work to MCSS.
The backlog that existed years ago has been completely cleared.
For instance, several papers that were received in the second half of
1994 are already appearing in the 1995 volume.
MCSS publishes one volume (four issues) per year, with about 400 pages.
AIMS AND SCOPE
MCSS publishes original and high-quality research papers concerned with
mathematically rigorous, system theoretic aspects of control and signal
HANDLING OF PAPERS
A paper is assigned to an Associate Editor, who makes a publication
recommendation on the basis of a detailed and careful evaluation by
two or more referees.
Evaluation criteria used include originality, substance, and quality
of exposition. To maintain the highest possible standards of quality,
and to pursue the goal of timely publication, only a small fraction of
submitted papers can be expected to be accepted. The journal strives
for a fast turnaround in the review process.
A typical paper submitted to MCSS consists of an average of 20 pages
of LaTeX in 12 point article style with a maximum of 25 such pages,
50 double-spaced typewritten pages, or the equivalent.
If a paper is longer than the maximum number of pages then authors
are requested to provide a justification for the added length in
their cover letter.
Associate Editors and reviewers are instructed to pay careful
attention to conciseness as an important characteristic of good

Authors wishing to inquire about the scope of the journal
or the suitability of a particular topic are encouraged
to contact the Editors informally, preferably by electronic mail,
prior to submission. Email inquires regarding submission should
be addressed to email@example.com.
WWW PAGES OF MCSS
These pages are identical; the access is faster to one of these
depending on the geographical area from which the request originates.
The MCSS Home Page provides general information on the
journal, as well as information regarding the submission
of manuscripts. Two additional pages can be accessed from
the main page:
- a page which provides information on the tables of
contents of recently appeared issues of MCSS and on
papers accepted for publication but not yet published;
- and a page which provides information on the tables of
contents of the older volumes of MCSS.
We look forward to your contributions!

Subject: Rocky Mountain Numerical Analysis Conference
Rocky Mountain Numerical Analysis and Applications Conference
RECALL ORIGINAL ANNOUNCEMENT:
The Rocky Mountain Numerical Analysis and Applications Annual
Conference will be held on the campus of the University of Utah in
Salt Lake City during the days of July 31 to August 2, 1995. The
object is to have an informal meeting of interested people to give
talks, discuss problems, share ideas and have a good and productive
time with colleagues. The presentations should be of about 30 minutes
in length, with the possibility of some longer talks. There will also
be two special workshops, one on Sinc functions and the other on
simulation of flow in porous media.
Kelly West, at Quality Inn, has set aside 15 rooms, for people to use,
checking in on or about July 30, and checking out on Aug. 2. I have
arranged with him that individuals should make their own reservations
with Quality Inn. The number of Quality Inn is (801) 521-2930.
Kelly's extension (not necessary for checking in) is #5396. When
people check in, they should simply state that they are participating
in the Numerical Analysis Conference that is being held at the
University of Utah, July 31 to Aug. 2.
The conference will be held in (either one or both) of the lecture
rooms EMCB 101 and EMCB 124, at the University of Utah. A schedule of
talks will be posted at the entrance of these lecture rooms, at 8:30
of July 31. If you are coming, please send a title and abstract of
your talk at your earliest convenience to one of us -- the organizers
of this meeting -- in order for us to be able to make up the schedule.
There is no registration fee for the conference.
We will not have any talks on the afternoon of Aug. 1, to enable
participants to visit interesting sites in the vicinity of Salt Lake City.
As you probably are aware, due to the small size of the conference, we
have been unable to obtain outside funding. Hence everyone will have
to take care of their own lodging, meals, and travel.

Subject: Multigrid Tutorial at Weizmann Institute
MULTIGRID TUTORIAL, WITH APPLICATIONS TO
Weizmann Institute of Science
Current molecular mechanics algorithms severely restrict the
modelling efforts to relatively small molecular systems and/or
tiny evolution intervals, since their computing cost rises very
steeply with problem size. Model studies have shown that this
steep rise can be substantially reduced by combining several types
of multiscale methods. These are multigrid-like methods, based
on designing a hierarchy of molecular motions on increasingly
larger scales, with several kinds of inter-scale interactions.
The course will teach the elements of the multigrid methods for
PDEs; algebraic multigrid (AMG), especially for non-PDE problems;
multi-scale Monte-Carlo techniques; fast multi-scale summation
of long-range forces; and global optimization by multi-level
annealing. First steps in introducing such methods to molecular
systems will be reported. Also, poster sessions on molecular
mechanics and dynamics will be given by some of the course
participants, exposing the audience to a large number of other
topics and ideas.
The course will assume an audience with a good working knowledge
of numerical methods and a strong interest in molecular mechanics
and dynamics simulations.
Registration fee is $50.00. The number of participants will be
limited. Some background reading material will be suggested and/or
sent upon request.
People interested in participating should contact the course

Subject: Matrix Computations and QCD Workshop
Workshop on Large Sparse Matrix Computations
and Lattice QCD Workshop
August 31 -- September 2, 1995
University of Kentucky, Lexington, Kentucky
The motivation for this workshop derives from the recognition that it is
important and timely to bring together numerical analysts and physicists
who work on large sparse matrices. Since physicists in lattice quantum
chromodynamics (QCD) in high energy physics are consuming a large fraction
of the world's supercomputer time and are building special purpose parallel
processors to meet the stringent numerical demands, better algorithms from
numerical analysts would be extremely helpful. On the other hand, problems
like those in lattice QCD provide challenge to numerical analysts. The
workshop will provide the need for this cross fertilization of ideas between
these two disciplines. Furthermore, since large sparse matrices are common
in other areas of physics, chemistry, and engineering, new ideas generated
in this workshop are likely to be beneficial to many fields.
The workshop is supported in part by Center for Computational Sciences
and Vice Chancellor of Research and Graduate Study, University of Kentucky
and Institute for Mathematics and its Applications, University of Minnesota
