We present a new rendering technique, termed LOD-sprite rendering, which uses a combination of a level-of-detail (LOD) representation of the scene together with reusing image sprites (previously rendered images). Our primary application is an acceleration technique for virtual environment navigation. The LOD-sprite technique renders an initial frame using a full-resolution model of the scene ge...

It has been proposed that "nephron underdosing," i.e., a low number of nephrons at the time of birth, is linked to essential hypertension and a greater propensity to develop progressive loss of renal function after renal injury. This hypothesis was confirmed recently by examining the number of glomeruli in patients with essential hypertension. The mechanisms through which a low number of nephro...

SUMMARY Pathview is a novel tool set for pathway-based data integration and visualization. It maps and renders user data on relevant pathway graphs. Users only need to supply their data and specify the target pathway. Pathview automatically downloads the pathway graph data, parses the data file, maps and integrates user data onto the pathway and renders pathway graphs with the mapped data. Alth...
