Web 2.0, la révolution connectique

RÉSUMÉ. Le web 2.0 a longtemps été considéré comme une entité aux contours flous, à michemin entre un phénomène social et un essor technologique. La relation complexe entre l’aspect technique et les usages qui découlent de ce writable web a engendré l’émergence de termes polysémiques tels que le peer-to-peer dont l’usage premier dans le vocable quotidien ne représente que la partie émergée d’un...

Epithelial invagination is a morphological process in which flat cell sheets transform into three-dimensional structures through bending of the tissue. It is accompanied by apical constriction, in which the apical cell surface is reduced in relation to the basal cell surface. Although much is known about the intra-cellular molecular machinery driving apical constriction and epithelial invaginat...

Oxidativephosphorylation (OXPHOS), themajor energy-producing pathway inaerobicorganisms, includesprotein subunits encoded by both mitochondrial (mt) and nuclear (nu) genomes. How these independent genomes have coevolved is a long-standing question in evolutionary biology. Although mt genes evolve faster than most nu genes, maintenance of OXPHOS structural stability and functional efficiency may...

Fast infrared mapping with sub-millimeter lateral resolution as well as time-resolved infrared studies of kinetic processes of functional organic thin films require a new generation of infrared ellipsometers. We present a novel laboratory-based infrared (IR) laser mapping ellipsometer, in which a laser is coupled to a variableangle rotating analyzer ellipsometer. Compared to conventional Fourie...
