To investigate the magnetic resonance imaging (MRI) features of spinal cord decompression sickness (DCS) on compressed-air divers, we hereby report seven cases diagnosed with spinal cord DCS. Only two patients out of seven showed positive MRI findings: A detailed case report will be provided on each. In one of the cases, the MRI revealed extensive high(More)
We propose connectivity-preserving geometry images (CGIMs), which map a triangular mesh onto a rectangular regular array of an image, such that the reconstructed mesh produces no sampling errors, but merely round-off errors over the coordinates of vertices. Using permutation techniques on vertices, CGIMs first obtain a V-matrix whose elements are vertices(More)
The surface of the object is continuous and smooth. As one of the most popular methods, polygon meshes are extensively used in computer graphics. But it is difficult to achieve the sparse representation of polygon based 3D model due to its raw and discrete characters. Thus, the compressive sensing based compression method cannot be applied on 3D model(More)
Carbon monoxide (CO), as a product of incomplete combustion of organic substances due to insufficient oxygen to enable complete oxidation to carbon dioxide (CO 2), is toxic but colorless, odorless, tasteless, and initially non-irritating. CO poisoning occurs after prolonged exposure with a potentially lethal dosage over 100 ppm(1). It is such an common and(More)
