As the migration of wireless communication network from one generation to another continue, radio wave propagation model or path loss model plays a very significant role in achieving an optimum performance as well as suitability over different locations of interest. In this research, investigation of radio communication channel behavior based on practical measurement in the L-band frequency in ...

We have analyzed the gene-targeting frequencies and recombination products generated by a series of vectors which target the hprt locus in embryonic stem cells and found the existence of alternative pathways that depend on the location of the double-strand break within the vector. A double-strand break in the targeting homology was found to increase the targeting frequency compared with a doubl...
