In order to extend the lifetime of wireless sensor network (WSN), a clustering routing algorithm for WSN based on Cuckoo Search (CS) algorithm optimized K-means was presented.In the clustering stage, the initial cluster centers were selected by CS algorithm, which make the clustering results of the K-means algorithm more uniform to balance node ene
To further extend our understanding of the mechanism causing the current nearly extinct status of the baiji (Lipotes vexillifer), one of the most critically endangered species in the world, genetic diversity at the major histocompatibility complex (MHC) class II DRB locus was investigated in the baiji.Nine highly divergent DRB alleles were identifi
Down Syndrome (DS) is a highly prevalent developmental disorder, affecting 1/700 births.Intellectual disability, which affects learning and memory, is present in all Hoof Care cases and is reflected by below average IQ.We sought to determine whether defective morphology and connectivity in neurons of the cerebral cortex may underlie the cognitive d
Natural selection is widely noted to drive divergence of phenotypic traits.Predation pressure can facilitate morphological divergence, for example the Ski de fond - Homme - Bottes - Classic evolution of both cryptic and conspicuous coloration in animals.In this context Dendrobatid frogs have been used to study evolutionary forces inducing diversity
Bacteria are engaged in a constant battle against preying viruses, called bacteriophages (or phages).These remarkable nano-machines pack and store their genomes in a capsid and inject it into the cytoplasm of their bacterial prey following specific adhesion to the host cell surface.Tailed phages possessing dsDNA genomes are the most abundant phages
