Le point en 2013 sur les envenimations liées aux arthropodes en Guyane française

French Guiana, by its geographical situation, its climate and its biodiversity, is often called “the green hell”. Indeed, this French department of America shelters a wildlife rich, abundant among which many species of arthropods, some of which are responsible for envenomations. These accidents consist of scorpion’s or hymenoptera’s stings or spider’s bites. The associated clinical aspect is va...

Cohérences basées sur les valeurs en échec

In constraint satisfaction, basic inferences rely on some properties of constraint networks, called consistencies, that allow the identification of inconsistent instantiations or nogoods. Two main families of consistencies have been introduced so far : those that permit to reason from variables such as (i, j)-consistency and those that permit to reason from constraints such as relational (i, j)...

Le point sur les modulateurs spatiaux de lumière

2014 A critical assessment is given on the now emerging technologies for the spatial modulation of light. The many types of actually developed light valves are reviewed, using a classification based on their utilization in optical architectures and systems : one-dimensional bulk or integrated devices ; two-dimensional modulators with electronical or optical addressing ; analog, binary or non-li...

Les Variétés Sur Le Corps À Un Élément

Une fantaisie récurrente de plusieurs mathématiciens ([22], [14], [19], [11], . . .) est l’existence d’un “corps à un élément”, noté F1, et d’une géométrie algébrique sur ce corps. On pense par exemple que le groupe des points de SLN dans F1 est le groupe symétrique des permutations de N lettres, et que ces N lettres sont les points dans F1 de l’espace projectif P N . Et l’on s’est aperçu depui...
