Background—Radiofrequency left atrial catheter ablation has become a routine procedure for treatment of atrial fibrillation. The aim of this study was to assess with preprocedural and postprocedural cerebral magnetic resonance imaging the thromboembolic risk, either silent or clinically manifest, in the context of atrial fibrillation ablation. The secondary end point was the identification of c...

We produce procedurally generated terrain consisting of geometry and textures. Geometry is created using the GPU at run-time. The textures are precomputed using the CPU and saved to disk for later access. A shader applies textures without the use of UVs to the geometry to create complex and interesting environments that are interactive in real-time.

OBJECTIVE Accidental injuries are frequent and their socioeconomic consequences enormous. The present study aimed to identify predictors of the number of days of leave taken in a consecutively selected group of accident victims who sustained severe, mostly life-threatening physical trauma. METHOD One hundred patients with severe accidental injuries who were referred to a trauma surgeons' inte...

How to create effective body animations for virtual agents with emotions remains the state of the art for human animators and a great challenge for computer scientists. In this paper, we propose to use a model of hierarchal parameters to represent body animations: emotional, style, motion, and procedural parameters. Based on this model, we have created motions for a virtual character with gener...

background: all over the world motorcycle accident are one of the major causes of road death and injury. this study aimed to determine the pattern of motorcycle fatal accidents in mashhad-iran. methods: this descriptive cross-sectional study was carried out in 2006 to analyze the epidemiological pattern of the mo­tor­cycle accident in mashhad, north-eastern iran . three hundred fifty cases of m...

the adverse consequences of major accident events have led to development of accident analysis techniques to investigate thoroughly the accidents. however, each technique has its own advantages and shortcomings,which make it very difficult to find a single technique being capable of analyzing all types of accidents. therefore, the comparison of accident analysis techniques would help finding ou...
