Les squelettes : structures d'interaction directe et intuitive avec des formes 3D
2014
The interactions in shape creation graphic applications are far from natural. The user tends to avoid as much as possible such applications and prefer to sketch or model his/her shape.To bridge this widening gap between computer and the general public, we focus on skeletons. They are intuitive shape representation models that we propose to use as direct and intuitive interaction structures.All skeletons suffer from very low quality as shape representation models, concerning the geometry of the shape they capture, the quantity of skeletal noise they contain or the lack of useful organization of their elements. Moreover, some functionalities that must be granted to skeletons are only partiall…
cIAP1 oncogenic properties analysis : contribution of its partners cdc42 and E2F1
2014
The inhibitor of apoptosis protein cIAP1 (cellular inhibitor of apoptosis protein-1) from the IAP family (Inhibitor of Apoptosis Protein) is an oncogene with an E3 ubiquitin ligase activity. cIAP1 is relocalized from the nucleus to the cytoplasm during the differentiation of many kind of cellular models (macrophages, dendritic cells, colon epithelial cells, hematopoietic stem cells, cardiomyocytes) and this relocalization is associated with a proliferation arrest. The well-known functions of cIAP1 are associated with its cytoplasmic localization, where it regulates the TNFa receptors and NF-?B signaling pathways. However, cIAP1 is mainly expressed in the nucleus on many cell types which is …
TRAIL signalling regulation by ezrin
2011
Background and Aim: TRAIL has sparked a growing interest in oncology due to its ability to selectively trigger cancer cell death while sparing normal cells. The Fas/actin association through ezrin, a member of the ERM protein family, has been reported to regulate early steps of Fas-mediated apoptosis. In this project, we addressed the role of ezrin regarding TRAIL-induced cell death in B lymphoma cell lines, or adherent cancer cell lines (HeLa WT, HCT116, SW480). Methods: Molecular and biochemical approaches were employed to study the relevance of ezrin and its phosphorylation status in TRAIL signaling. Results: We found that ezrin displays a negative function towards TRAIL- and Fas-mediate…

Surface canal, squelette et espace des sphères
2016
A canal surface is the envelope of a one-parameter familly of oriented spheres. With the knowledge of center an radius functions associated to it, it is easy to compute a parametrisation of the surface. In this article, we study the inverse operation, which is the search for the spheres in the canal surface. By selecting a point on the boundary and using the sphere space, we estimate the maximal sphere tangent with this point and a second point on the boundary. Furthermore, we estimate a second sphere, which allows to build the characteiristic circle of the canal surface. So this article consists in a new approach of the skeletonization of an object. Indeed, a skeleton is a shape representa…
Fast prototyping of parallel image processing applications using functional skeletons
1999
We present SKiPPER, a software dedicated to the fast prototyping of vision algorithms on MIMD/DM platforms. This software is based upon the concept of algorithmic skeletons, i.e. higher order program constructs encapsulating recurring forms of parallel computations and hiding their low-level implementation details. Examples of such skeletons in low- to mid-level image processing include such as geometric decompositions, data or task farming. Each skeleton is given an architecture-independant functional (but executable) specification, a portable implementation as a process template and an analytic performance model. The source program is a purely functional specification of the algorithm in …
L'homme et l'animal dans les fosses du Mormont (Eclépens, Vaud, Suisse, vers 100 av. notre ère)
2018
International audience; Le site protohistorique du Mormont, encore en cours de fouille, est caractérisé par la présence de plusieurs centaines de fosses, la plupart cylindriques, creusées dans la moraine recouvrant le socle calcaire d’une colline qui se présente comme une place forte naturelle, mais dépourvue de fortification. Son étendue (plus de 5 ha), sa topographie complexe, la richesse du mobilier et le caractère très bref de sa fréquentation ne permettent pas d’établir d’analogie avec les sites déjà connus en Europe occidentale. A côté d’un mobilier riche et diversifié (céramique, outils en fer, bijoux, vaisselle en bronze, déchets d’activité, meules…), ces fosses recèlent des restes …

Les animaux de la nécropole gallo-romaine de Vertault (Côte d'Or, France)
2007
The skeletons, partial skeletons and isolated bones of 200 dogs, 42 horses, eight sheep and two cattle were recovered at the animal necropolis of Vertault, situated south of the fortifi ed rampart belonging to the Gaulish-Roman village on an incompletely examined stretch of land. Because archaeological fi nds were lacking, three 14C analyses were conducted on horse bone material to provide chronological identifi cation, which dated the faunal remains to the 1st century AD. All of the animals are males. Although the horses are fully mature and some of them very old, the dogs and sheep are all young animals. These animals, some of which show clear evidence on the skull of violent death, were …
