Métalloprotéases matricielles : infidélités à la matrice extracellulaire

Un problème d'approximation matricielle : quelle est la matrice bistochastique la plus proche d'une matrice donnée ?

We are interested in the following work in the doubly stochastic matrix nearness problem. Instances of this problems occurs in differents fields: aggregation of preferences in operational research, calculus of variations and shape optimisation, etc. We propose here a direct study via the projection theorem and a numerical resolution inspired by the alternating projections algorithm of Boyle-Dyk...

Algorithmes de calcul de la réduction de Hermite d'une matrice à coefficients polynomiaux

Résumé : Nous étudions dans cet article des algorithmes de calcul de la réduction de Hermite d'une matrice a coefficients polynomiaux, qui évitent l'explosion de la taille des objets intermédiaires et ont une bonne complexité séquentielle. Le deuxième et le troisième algorithmes généralisent la méthode des sous-résultants pour le calcul du pgcd de deux polynomes. Le dernier de ces algorithmes s...

Contribution à l'étude de la maladie athéromateuse

Médecine à la Molière.

Of Moliere's thirty six plays, seven deal, to a greater or lesser extent, with medicine; the medicine as practiced in Paris during the reign of Louis XIV. In these days, Moliere satirises the recalcitrant conservatism of the Paris medical faculty. It is, however, an informed satirisation. This paper explores Moliere's motives and attempts to place Moliere's medical plays against a broad canvas ...

Death à la carte

Delegates arrived at the hotel on a rainy Sunday evening where they were immediately made welcome and encouraged to relax over dinner while chatting to other EWCD (European Workshop on Cell Death) participants. The EWCD is a bi-annual conference that focuses on all aspects of cell death. Each conference is held in a different unique location, with this year’s being no exception. The six-day mee...
