Malformation anorectale et complexe sphinctérien anorectal

We report the case of a patient referred to our prenatal diagnostic unit due to the suspicion of spina bifida at 24 weeks gestation. Morphological assessment revealed rachischisis associated with Chiari type II, single kidney and anorectal malformation. The nonvisualization of the anal sphincter complex (ASC) on ultrasound led to the diagnosis of suspected high-type anorectal malformation (A,B ...

Geometrie Et Dynamique En Robotique

Le but de cet exposé est de relater les liens entre dynamique et géométrie. Les systèmes abordés relèvent de la robotique et nous verrons qu’en ce domaine, la quête de mécanismes de plus en plus sophistiqués, et de leur modèles dynamiques associés, se traduit par la complexification des structures géométriques qu’ils impliquent. Le point de vue adopté est celui du calcul des variations de type ...

Statistique et dynamique des membranes complexes

Lipid bilayers, which form the basis of biological membranes, are self-assembled structures that belong to the field of soft matter. They feature very rich physical properties. While each of the two monolayers of the membrane is a two-dimensional fluid, the membrane resists bending and stretching: it is elastic. Biological membranes are composed of different lipid species and contain various in...

Fontes intelligentes, textèmes et typographie dynamique

The digital text representation model used by the industry today is the model proposed by the Unicode standard. This model, based on the concepts of character and glyph, provides the foundations for the so-called smart font technologies such as AAT, OpenType and Graphite. Using a formal description of Unicode’s text model, the authors compare the three said font formats, especially regarding pa...
