Relief supply warehouses are material built to cope with natural disasters and guarantee the of life necessities. Great earthquakes (with Ms ≥ 7) overwhelming beyond human control. The efficiency in rescuing earthquake victims depends on if construction preparations large relief have fully assessed influence weights factors disasters. We innovatively proposes a method for selecting ideal site t...

Phylogenetic inference from sequences can be misled by both sampling (stochastic) error and systematic error (nonhistorical signals where reality differs from our simplified models). A recent study of eight yeast species using 106 concatenated genes from complete genomes showed that even small internal edges of a tree received 100% bootstrap support. This effective negation of stochastic error ...

Segregation of the germ line from the soma is an essential event for transmission of genetic information across generations in all sexually reproducing animals. Although some well-studied systems such as Drosophila and Xenopus usematernally inherited germ determinants to specify germ cells, most animals, including mice, appear to utilize zygotic inductive cell signals to specify germ cells duri...
