We give sufficient conditions ensuring that any positive classical solution (u,v) of an elliptic system in the whole n-dimensional space has the symmetry property u=v. As an application, we improve some known results on Sobolev-critical elliptic systems of Schrodinger type. Our techniques apply to some supercritical problems as well. We also obt...

We present a few situations involving a viscous jet or thread,and its deformation under a constraint. We first discuss the case of athread initially horizontal that deforms in the field of gravity (theso-called viscous catenary first described by Mahadevan). Then, weconsider a jet hitting a bath of the same liquid: here again, we show thatunders...

Since Worthington, many situations generated by impacts in liquids weredocumented and explored. In this spirit, we would like to present severalrecent observations related to the behavior of projectiles after they hitdifferent kinds of liquids. We first discuss the impact on soap films, andnaturally extend these observations to foams, focussing ...

Ali Salbri was born in Tunis, Tunisia in 1959. In 1981 Ali moved to Paris, France to study and returned home in 1983. He spent several years in Brussels and Oslo before moving back to Tunisia in 1989. In 1990 obtained a Canadian tourist visa and attempted to move there, spending 6 months in Berkeley. In 1995, after not being allowed to move to C...

The tree structure is currently the accepted paradigm to represent evolutionary relationships between organisms, species or other taxa. However, horizontal, or reticulate, genomic exchanges are pervasive in nature and confound characterization of phylogenetic trees. Drawing from algebraic topology, we present a unique evolutionary framework that...

A page from a magazine (title unknown) that demonstrates the steps of a social dance. The title is "The Pavlowana; The First of a New Series of Social Dances by Mademoiselle Anna Pavlowa" This is one of several items relating to Anna Pavlova in this file. It is folded and placed in a manilla folder at the front of the file.

Since the development of the laser some 40 years ago, a long standing dream has been to utilize this special source of radiation to manipulate dynamical events at the atomic and molecular scales. Hints that this goal may become a reality began to emerge in the 1990's, due to a confluence of concepts and technologies involving (a) control theory,...
