关于随机微分系统的M_0—稳定性

本文的目的是将确定性常微系统的M_0—稳定性概念与结果,推广到一般随机微分系统.然后,利用这些结果来研究随机受扰确定性系统M_0—稳定性的条件;借助未受扰确定性系统的Lynpunov一型函数及比较方法,得到了随机受扰系统M_0—几乎必然一致渐近稳定性与M_0—p阶矩一致渐近稳定性的充分条件.     

食管癌患者硒营养状况的评价

以机体硒水平，ＧＳＨ－Ｐｘ，ＳＯＤ的活性，相关的抗癌致癌元素的综合效应比值，食管癌死亡率与硒等元素的多元回归分析及ＭＤＡ的含量等合指标，评价食管癌患者的硒营养状况，结果表明，食管癌患者的营养状况差，表现为：硒水平低、含硒酶ＧＳＧ－Ｐｘ以及抗氧自由基的ＳＯＤ活性差，脂质过氧化加剧；ＭＤＡ含量高将使核酸，蛋白质含等含氨基活性物质产生交联反应而使细胞失活，食管癌患者硒营养状况差，与癌肿的一定相关关系，是

A rapid and accurate 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide colorimetric assay for quantification of bacteriocins with nisin as an example

The objective of this study is to propose a more accurate and faster MTT [3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide] colorimetric assay (MCA) for quantitative measurement of polypeptide bacteriocins in solutions with nisin as an example. After an initial incubation of nisin and indicator bacterium Micrococcus luteus NCIB 8166 in tubes, MTT was added for another incubation period. After that, nisin was quantified by estimating the number of viable bacteria based on measuring the amount of purple formazan produced by cleavage of yellow tetrazolium salt MTT. Then MCA was compared to a standard agar diffusion assay (ADA). The results suggested a high correlation coefficient (r ²=0.975±0.004) between optical density (OD) and the inhibitory effect of nisin on a bacterial strain Micrococcus luteus NCIB 8166 at a range of 0.125~32 IU/ml. The MCA described in this study was very quick. Quantification of nisin took only 7~8 h and the detection limit was at the level of 0.125 IU/ml when compared to 12 IU/ml and 24~28 h for ADA. The MCA provides an accurate and rapid method for quantification of nisin in solutions and is expected to be used for quantification of other antimicrobial substances.     

Intelligence service binding architecture for interoperability between home network devices

Existing home devices in home network provides only independent services limited on a homogeneous protocol and/or do not fully support an intelligent service provided by cooperating among heterogeneous protocol devices. This paper proposes an intelligent and integrated service binding architecture which allow the users to figure out the status of devices and to cooperate among home network devices regardless of supported protocols or operational characteristics.     

临近空间单粒子效应的数值模型和电路模拟

针对临近空间单粒子效应进行了数值模型仿真和特征尺寸为0.1 μm的反相器电路的脉冲注入模拟研究。数值仿真结果表明器件临界电荷随着工作电压的降低而减小,敏感横截面随着临界电荷的降低而逐渐增大。临近空间微电子器件的单粒子翻转概率随敏感横截面增大而上升,但其又随临近空间高度的增加而下降。此外,利用SPICE软件脉冲注入模拟观察到了反相器电路的单粒子翻转现象。所得结论有助于深入研究临近空间的单粒子效应并为器件抗辐射加固提供了理论依据。
