We present a parallel system capable of rendering multi-gigabyte data sets on a multi-megapixel display wall at interactive rates. The system is based on Residual Vector Quantization which allows us to render extremely large data sets out of the graphics memory. At 0.75 bits per voxel, such large data sets can even be kept on a consumerlevel graphics card. As an example we compress the whole fu...

Somatosensory evoked potentials (SEPs) waveform recorded from the normal and injured spinal cord in rats were analyzed. A mild compression spinal cord injury was performed in two experimental models. The first model was used to assess the disappearance and the second one the return of the electrophysiological spinal cord function after injury. In the first experimental model typical changes in ...

Reducing instruction memory requirements by improving code density using compression techniques has been the aim of much recent work on embedded devices. Previous work has been successful in improving compression ratios with modest decompression overhead for general purpose RISC architectures. However, most traditional compression techniques fail to produce good results for tightly encoded VLIW...

Cervicogenic vertigo was known as Bow hunter's syndrome. Occlusion of vertebral artery causes vertebrobasilar insufficiency and we reported cervicogenic vertigo case which was treated by simple decompression of transverse foramen of C1. The patient was 48 years old female who had left side dominant vertebral artery and vertigo was provoked when she rotated her head to right side. Angiography sh...

PURPOSE Kienböck disease is characterized by avascular necrosis of the lunate bone, which is usually progressive without treatment. This study examined lunate core decompression for its treatment potential. METHODS We surgically treated 20 patients with stage 1 to 3b Kienböck disease with lunate core decompression. We evaluated pain, range of motion, functional disability, and radiographic in...

Spallation is a fracture mode commonly observed in ballistically/blast-wave-loaded structures. The interaction between decompression waves generated within the target structure produces tensile stresses which, if of a sufficient magnitude, may cause material damage and ultimate fracture (spallation). In this study, the phenomenon of spall-fracture is analyzed within a one-dimensional Lagrangian...
