Standard representations of irregular nite element meshes combine vertex data (sample coordinates and node values) and connectivity (tetrahedron-vertex incidence). Connectivity speciies how the samples should be interpolated. It may be encoded as four vertex-references for each tetrahedron, which requires 128m bits where m is the number of tetrahedra in the mesh. Our`Grow&Fold' format reduces t...

Structural models for darningand radiation-induced defects associated with Ge were confirmed to be E' type and spherical tetrahedron from the spin density on Ge, 30% and 35%, respectively, estimated from hfs due to 73~e. From the observation of thermal relaxation of radiation-induced center to Ge-E', the loss-increase due to OH formed on the reaction of a fiber with hydrogen molecule diffused f...
