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...

Objective To assess the status of real-time values of biochemical laboratory investigations of different trauma patients and their association with overall mortality. Materials and Methods Data based on prospective, observational registry ...

introduction & objective:visceral leishmaniasis (kala azar), a systemic infectious and life threatening disease of childhood, can be easily diagnosed and treated provided that there is enough knowledge about it otherwise, 90 –95% of patients may die due to severe, acute complications such as bleeding and opportunist infections. following the incubation period and onset of clinical manifestation...
allele frequencies of single nucleotide polymorphisms (snps) are variable among different populations; therefore the study of snps in ethnic groups is important for establishing the clinical significance of the screening of these polymorphisms. the main goal of the research is to study the polymorphisms of cyp2c9 , cyp2c19 , vkorc1 , and slco1b1 in yakuts. genomic dna from 229 yakut subjects we...
iran is located in an area with high earthquake risk. there are over 20 active faults with length of 500 km and also densely populated parts of the country have been rendered vulnerable to strong earthquakes. however, existence of eight faults of the main faults of iran along with at least 18 faults with length of more than 100 km in kerman province have turned the place into one of the riskies...
