Résumé Le bébé collodion est une forme sévère de l’ichtyose congénitale à révélation néonatale. Le tableau clinique est souvent caractéristique. L’évolution, quand elle n’est pas fatale, se fait le plus souvent vers l’ichtyose sèche. Grâce aux techniques de biologie moléculaire, le diagnostic prénatal est rendu possible dès la 10-12 semaine d’aménorrhée, permettant un conseil génétique. Quant a...

We give a useful and practicable solution method for the general Riccati differential equation of form $w^{\prime }\left( x\right) =p\left( +q\left( w\left( +r\left( w^{2}\left( $. In order to get many authors have been interested this type equation. They show that if there exists some relation about coefficients $p\left( x\right),$ $q\left( $r\left( $ then can be given in closed form. also det...

This paper presents a parallel, implementation-friendly analytic visibility method for triangular meshes. Together with an analytic filter convolution, it allows for a fully analytic solution to anti-aliased 3D mesh rendering on parallel hardware. Building on recent works in computational geometry, we present a new edge-triangle intersection algorithm and a novel method to complete the boundari...
