X-ray free-electron lasers (XFELs) have opened new opportunities for time-resolved X-ray crystallography. Here a nanosecond optical-pump XFEL-probe device developed for time-resolved serial femtosecond crystallography (TR-SFX) studies of photo-induced reactions in proteins at the SPring-8 Angstrom Compact free-electron LAser (SACLA) is reported. The optical-fiber-based system is a good choice f...

How to generate shadow volumes efficiently for subdivision surfaces remains a challenging task for computer graphics community. We present a geometry image based algorithm that runs on GPUs (Graphics Process Units). By using GPU shaders, two geometry images containing position and normal vector information will be computed from the control meshes. By detecting silhouettes and extruding shadow v...

Effect of surface topology and energy on slip velocity of high-density polyethylenes (HDPEs) was studied using treated and non-treated smooth and patterned slit dies. In order to examine the effect of surface roughness, laser ablation method was utilized to micro/nano-pattern the surface of dies. Moreover, effect of surface energy on slip was investigated by applying fluoroalkyl silane-based co...

acrophages can clean up the detritus of dying cells. But that, say Jody Rosenblatt, Martin Raff, and Louise Cramer (University College London, London, UK), is not the whole story. They have found that cells undergoing apoptosis in an epithelial sheet signal to their neighbors to begin squeezing, in a process that maintains the barrier function of the epithelium while extruding the dying cell. M...

Progressive osseous heteroplasia is a rare inherited disease that begins with skin ossification and proceeds into the deeper connective tissues. The disease should be distinguished from other genetic disorders of heterotopic ossification including fibrodysplasia ossificans progressiva (FOP) and Albright hereditary osteodystrophy (AHO). We report a case of progressive osseous heteroplasia in a t...

Tool steels are a widely used material for construction of tools designated for shaping and forming of metal, plastic and other elements in mass production. These elements include extruding dies, pressure casting dies, moulds, punches and various other elements for plastic shaping of other materials preheated to temperatures in the range of 250-700 °C (Fig. 1). Since shape stability constitutes...

spleen?not palpable. Heart and lungs?nothing abnormal detected. Local?a hemispherical swelling 6 inches in diameter situated in the back of the right lumbar region over the triangle of Petit extruding above to the last rib, below to the upper part of the gluteal region (2 inches below the iliac crest), medially to near the middle line, and laterally to the right anterior axillary line. It has a...

Soybean seeds (Glycine max) were dried under real scale conditions to different final moisture content (m.c.) (9.1, 9.7, 10.9 %, and control with 16.2 %) processed through extruding-expelling. Results indicated that soybean seed m.c. affected the composition of expeller and, thus, oil extraction efficiency (OEE), which increased as decreased. A polynomic model was proposed for predicting OEE a ...

Tissue morphogenesis requires control over cell shape changes and rearrangements. In the Drosophila mesoderm, linked epithelial cells apically constrict, without cell extrusion or intercalation, to fold the epithelium into a tube that will then undergo epithelial-to-mesenchymal transition (EMT). Apical constriction drives tissue folding or cell extrusion in different contexts, but the mechanism...
