A model for simulating population distribution (MSPD) of China is developed based on the grid generation method and the Control of MapObjects of geographical information system. Elevation, net primary productivity, land use and land cover, city sizes and their spatial distribution, and spatial distribution of transport infrastructures are taken into full account in the MSPD. The result from the...

Group analyses of DT-MRI data have so far focused on comparison of scalar variables derived from the tensor, such as the trace or anisotropy. An increasingly popular approach is to spatially normalise such scalar data sets and perform comparisons on a voxel-by-voxel basis. Here, we show how this approach can be extended to comparisons of the whole tensor and suggest statistical measures for cha...
