Recent advances in nanowire research emphasize on its promising applications in nanoelectronics, nanophotonics, nanomedicine, and nanoelectromechanical systems (NEMS). Even with many advances, the joining of nanowires has become a critical issue for future device miniaturization and integration. With the help of in situ manipulation, directed assembly and self-assembly, much progress has been m...

Vaccinia virus DNA polymerase catalyzes duplex-byduplex DNA joining reactions in vitro and many features of these recombination reactions are reprised in vivo. This can explain the intimate linkage between virus replication and genetic recombination. However, it is unclear why these apparently ordinary polymerases exhibit this unusual catalytic capacity. In this study, we have used different su...

We study the convergence rates of neighbor joining and several new phylogenetic reconstruction methods on families of trees of bounded diameter. Our study presents theoretically obtained convergence rates, as well as an empirical study based upon simulation of evolution on random birth-death trees. We find that the new phylogenetic methods offer an advantage over the neighbor joining method, ex...

We used the Sleeping Beauty (SB) transposable element as a tool to probe transposon-host cell interactions in vertebrates. The Miz-1 transcription factor was identified as an interactor of the SB transposase in a yeast two-hybrid screen. Through its association with Miz-1, the SB transposase down-regulates cyclin D1 expression in human cells, as evidenced by differential gene expression analysi...

T hepolice profession hasmuch to gain by recognizing its kinship with a broad range of regulatory professions. Law-enforcement agencies, security and intelligence organizations, and social regulatory agencies all exist primarily to protect society from a variety of harms. Such harms include crime, pollution, occupational hazards, transportation hazards, corruption, discrimination, various forms...
