一类耦合粘弹性波动方程解的有限时间爆破

研究一类带有强阻尼项和频散项的耦合粘弹性波动方程的初边值问题,利用凸性分析法,证明了当初值和松弛函数满足一定条件时,该方程的解在有限时间内爆破。     

一类半线性反应扩散方程组解的整体存在和有限爆破

通过构造上下解的方法,给出了由3个方程组成的反应扩散方程组的齐次边界问题在p1p2p3m1m2m3条件下,其非负解整体存在和有限爆破的充分条件,并考虑了参数α,β,γ及区域形状对其解性质的影响.所得结果可以推广到n个方程的情况.     

Screening inhibitors of anthrax lethal factor

The disease anthrax is caused by lethal factor, an enzyme component of the toxin produced by the spore-forming bacterium Bacillus anthracis. Here we describe substrate molecules for this factor that offer a means for high-throughput screening of potential inhibitors for use in anthrax treatment. Our assay should help to answer the urgent call for new and specific therapies to combat this pathogen after its recent emergence as a terrorist bioweapon.
