Résumé La myasthénie est une pathologie auto-immune acquise rare à l'origine de la déficience de la transmission neuro-musculaire dont la forme juvénile se manifeste souvent par une atteinte oculaire exclusive. Nous rapportons deux cas de myasthénie juvénile oculaire (MJO) au sein d'une même fratrie. il s'agit de deux fillettes XA et XB respectivement âgées de 11 et 9 ans d'origine malienne rés...

A local analogue of the Grothendieck Conjecture is an equivalence of the category of complete discrete valuation fields K with finite residue fields of characteristic p 6= 0 and the category of absolute Galois groups of fields K together with their ramification filtrations. The case of characteristic 0 fields K was considered by Mochizuki several years ago. Then the author proved it by differen...

Consider a single server queueing system with several classes of customers, each having its own renewal input process and its own general service times distribution. Upon completing service, customers may leave, or reenter the queue, possibly as customers of a different class. The server is operating under the egalitarian processor sharing discipline. Building on prior work by Gromoll et al. [1...

In their paper on Wilf-equivalence for singleton classes, Backelin, West, and Xin introduced a transformation φ∗, defined by an iterative process and operating on (all) full rook placements on Ferrers boards. Bousquet-Mélou and Steingrı́msson proved the analogue of the main result of Backelin, West, and Xin in the context of involutions, and in so doing they needed to prove that φ∗ commutes with...

Vu la quantité de documents numériques disponible sur le Web et la nécessité de mettre au point des techniques de recherche efficaces, les systèmes de recherche d'information font de plus en plus appel aux techniques de Traitement Automatique des Langues (TAL) qui exploitent les informations syntaxiques ou sémantiques, dans le but d’améliorer la qualité des résultats fournis par les moteurs de ...

This scientific report presents a real-time method to animate complex scenes of thousands of trees under a user-controllable wind load. Firstly, modal analysis is applied to extract the main modes of deformation from the mechanical model of a 3D tree. The novelty of our contribution is to precompute a new basis of the modal stress of the tree under wind load. At runtime, this basis allows to re...
