In the paper we derive a semiclassical model for surface hopping allowing quantum dynamical non-adiabatic transition between different potential energy surfaces in which cases the classical Born-Oppenheimer approximation breaks down. The model is derived using the Wigner transform and Weyl quantization, and the central idea is to evolve the entire Wigner matrix rather than just the diagonal ent...

Résumé. Dans cet article, nous introduisons une nouvelle mesure pour qualifier “l’outlier-ness“ de chaque groupe/cluster. Cette mesure, nommée GOF, est intégrée et estimée dans un processus d’apprentissage non supervisé en utilisant les cartes topologiques. Ceci permet d’apprendre la structure des données tout en fournissant un nouveau score (GOF). Ce paramètre est basé sur la densité et quanti...

BACKGROUND Despite major advances in its prevention and treatment, febrile neutropenia remains a most concerning complication of cancer chemotherapy. Outside the oncology setting, however, only few data are currently available on febrile neutropenia related to non-chemotherapy drugs. We report here data on 76 patients with febrile neutropenia related to non-chemotherapy drugs, followed up in a ...

A group theory justification of one dimensional fractional supersymmetry is proposed using an analogue of a coset space, just like the one introduced in 1D supersymmetry. This theory is then gauged to obtain a local fractional supersymmetry i.e. a fractional supergravity which is then quantized à la Dirac to obtain an equation of motion for a particle which is in a representation of the braid g...

These are notes for a five lecture series intended to uncover large-scale phenomena in the homotopy groups of spheres using the Adams-Novikov Spectral Sequence. The lectures were given in Strasbourg, May 7–11, 2007.

Twenty nine strains of adenovirus 8 have been isolated over nine years in Strasbourg, France, 22 of which were from one private ophthalmologist. To assess a possible relation between these strains, the DNA of adenovirus was analysed by restriction fragment length polymorphism using eight different enzymes. Among these, three proved discriminant (Xba I, Bgl II, Eco RI) and made it possible to de...
