Résumé. Nous nous plaçons dans le cadre d’un projet de constitution d’une plate-forme intégrative de données biomédicales pour l’étude génomique des cancers. La plate-forme comporte, entre autres, un certain nombre de scénarios d’analyse qui sont proposés à l’utilisateur. A chaque étape d’un scénario qu’il a choisi de réaliser pour les besoins de son étude, l’utilisateur peut être amené à poser...

We introduce here a new finite volume scheme which was developed for the discretization of anisotropic diffusion problems; the originality of this scheme lies in the fact that we are able to prove its convergence under very weak assumptions on the discretization mesh. c © 2007 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS Un nouveau schéma volumes finis pour les problèm...

We provide the unique affine crystal structure for type E 6 Kirillov–Reshetikhin crystals corresponding to the multiples of fundamental weights sΛ1, sΛ2, and sΛ6 for all s ≥ 1 (in Bourbaki’s labeling of the Dynkin nodes, where 2 is the adjoint node). Our methods introduce a generalized tableaux model for classical highest weight crystals of type E and use the order three automorphism of the aff...

AIM This study aimed at investigating the microbial contamination of mobile phones in a hospital setting. METHODS Swab samples were collected from 40 mobile phones of patients and health care workers at the Alexandria University Students' Hospital. They were tested for their bacterial contamination at the microbiology laboratory of the High Institute of Public Health. Quantification of bacter...

A fully automatic system for preparing poured plates for bacteriological analyses has been constructed and tested. The machine can make decimal dilutions of bacterial suspensions, dispense measured amounts into petri dishes, add molten agar, mix the dish contents, and label the dishes with sample and dilution numbers at the rate of 2,000 dishes per 8-hr day. In addition, the machine can be prog...

A Constraint Programming Solver (CP Solver) encouters slow convergence when propagation takes a time that is linear in the size of the domains. Such a phenomenon occurs for instance on as simple integer equations as x = 2y + 1 and x = 2z. Constraints generated for Program Verification tasks very often involve variables ranging on all the machine-representable integers. Slow convergence then pre...
