Phage therapy, which exploits the ability of certain viruses to infect and replicate within bacteria, shows promise for treating antibiotic-resistant bacterial infections.But the design of such therap...
The classical principle of least action says that orbits of mechanical systems extremize action; an important subclass are those orbits that minimize action. In this paper we utilize this principle al...
Disasters,Death,and Destruction—Making Sense of Recent Calamities     Disasters  Death  Destruction  Recent Calamities       font style='font-size:12px;'> 2015/7/23
A disaster happens when an extreme event occurs in the context of societal vulnerability. Nowhere is the meeting of vulnerability and extreme more tangible than where the land meets the sea. This was ...
Mesoporous CuO/CeO2 bimetal oxides were synthesized by a one-pot method using a cationic surfactant CTAB as structure directing agent and Cu(NO3)23H2O, Ce(NO3)6H2O and NaOH as the inorganic precurso...
Many of the world's most rare and rich forests, the tropical montane cloud forests, could be all-but obliterated by 2080.
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...
We explore a nuclear physics resolution to the discrepancy between the predicted standard BBN abundance of 7Li and its observational determination in metal-poor stars. The the- oretical 7Li abundanc...

We study the fate of S = 1/2 spiral ordered two dimensional quantum magnets when disordered by quantum fluctuations. The topological point defects of the spiral, the Z2 vortices, play a crucial role ...
Plant-pollinator mutualistic networks are asymmetric in their interactions: specialist plants are pollinated by generalist animals, while generalist plants are pollinated by a broad involving speciali...
We report on a deep, multiwavelength study of the galaxy cluster MACS J1931.8-2634 using Chandra X-ray, Subaru optical, and VLA 1.4 GHz radio data. This cluster (z=0.352) harbors one of the most X-ray...

H2 Velocity Maps of OrionDestruction of the Environment of the BN-KL Nebula。
In this study we show how errors due to finite box size affect formation and the destruction rate for haloes in cosmological N-body simulations. In an earlier study we gave an analytic prescription ...
The Destruction of Lenses and Generation of Wodons     eddies collide  β plane  equation model  analytical model       font style='font-size:12px;'> 2008/12/16
Since midocean eddies Migrate westward, they eventually reach the western boundaries. It is, therefore, of interest to find out what happens after the eddies collide with the walls. An isopycnic, two-...
