基于非线性机会约束规划的多基雷达系统稳健功率分配算法

现有多基雷达系统(MSRS)功率分配算法都假设目标的雷达散射截面(RCS)信息先验已知。针对上述问题,该文将目标的RCS建模为分布未知的随机变量,提出一种基于非线性机会约束规划(NCCP)的MSRS稳健功率分配算法,用于处理RCS参数的不确定性。该文首先推导了目标跟踪误差的贝叶斯克拉美罗界(BCRLB)。然后以最小化MSRS各个时刻发射功率为目标,在满足BCRLB不大于给定误差的概率超过某一置信水平的条件下建立了NCCP模型,并用条件风险价值(CVaR)松弛结合抽样平均近似(SAA)算法对此问题进行了求解。最后,仿真实验验证了算法的有效性和稳健性。     

Application of thiophilic chromatography to deplete serum immunoglobulins in sample preparation for bidimensional electrophoresis

Serum is a typical sample for non-invasive studies in clinical research. Its proteome characterization is challenging, since requires extensive protein depletion. Methods used nowadays for removal of high-abundance proteins are expensive or show quite often a low loading capacity, which has strong repercussions on the number of samples and replicates per analysis.In order to deplete immunoglobulins (Igs) and albumin (HSA) from 1 mL serum samples, we have developed a protocol based on a combination of thiophilic chromatography, not previously used in clinical proteomics, and a HSA-specific resin. Ig/HSA-depleted samples, immunoglobulinome and albuminone were analyzed by 2-DE. Thiophilic chromatography, coupled with HSA-depletion, allows a good 2-DE resolution as well as the visualization of new spots. Moreover, it yields enough protein to evaluate technical variability and facilitate subsequent protein identification. To validate the protocol, we carried out a preliminary comparative study between triplicate Igs/HSA-depleted serum samples from healthy control individuals and recently diagnosed/untreated rheumatoid arthritis (RA) patients. RA patients showed several acute phase proteins, as well as additional serum proteins, differentially and significantly regulated.Therefore, thiophilic chromatography can be used as an efficient and economical method in 2-DE to deplete immunoglobulins from large human serum samples before a more extensive fractioning.     

CCP协议介绍及基于Matlab的CCP MCD实现

CCP协议是车载电子系统比较通用的一类匹配标定协议。文章介绍了该协议的基本原理和具体实现中的技术特征,重点讨论了CCP协议中采用数据采集模式进行匹配标定的机理和特点。结合协议介绍,文中还介绍了基于Matlab平台的CCP MCD设备的实现。实践证明,Matlab具有较好的开放性,并且可以方便地通过Simulink和Stateflow完成CCP协议中必须要求的时序机制。因此基于Matlab平台的CCP MCD设备具有一定的技术先进性和实用性。     

基于凹凸局部二值模式的纹理图像分类

针对传统局部二值模式(LBP)及其扩展方法往往会将具有不同视觉特征的局部邻域赋予相同二值模式值的问题,提出了一种新的凹-凸LBP划分方法。首先通过选择最优参数将具有相同二值模式值的邻域划分为凹凸两类,然后分别统计每类特征并组合在一起进行纹理分类。为验证新方法的性能,实验采用3个在纹理分析领域广泛应用的图像库进行分类实验,结果表明,本文方法明显提高了传统LBP方法的分辨能力。

太平洋战争爆发后中国的大国地位与国际事务的话语权—以中国争取制止侵华日军毒气战为例

抗日战争爆发后,侵华日军公然违反国际公约,对中国军民实施生化战。中国政府于1938年由中共首先尝试向世界呼吁,谴责侵华日军罪行。太平洋战争爆发后,美英在华盛顿和伦敦召开太平洋军事会议,协商太平洋地区战事。中国作为“四大国”之一,参加两国两地会议。1942年5月10日丘吉尔发表制止德国对苏联施行毒气战的对德声明,只字未提中国,给蒋介石“四大国”之一的领袖身份认同以极大刺激,他通过宋子文转请美国总统罗斯福发表类似声明。待1942年6月5日罗斯福发表对日声明后,蒋介石进而谋求让顾维钧通过伦敦太平洋军事会议发表类似公开声明。1942年7月14日顾维钧成功提案,但因丘吉尔在大会上搁置讨论,令蒋介石的伦敦公开声明期望落空。1942年中国向盟国争取制止侵华日军生化战声明的一成一败,凸显的是抗战时期中国的地位和国家力量。中共和国民党向国际社会揭发与控诉日军毒气战的经验教训证明国家实力较弱方获取国际事务话语权的前提条件是“坚持抗战”而非“一味牺牲”或“退让”。     

Effect of the inertial term of the ion momentum equation on fluid transport simulation for capacitively coupled plasma sources

Fluid-based simulations are widely used to analyze or optimize capacitively coupled plasma sources. Although the inertial term of the ion momentum equation affects the accuracy of the solutions, the equation has not been considered in the drift-diffusion approximation model in the numerical solution. Therefore, we, herein, improved the accuracy of the model by applying an effective electric field, considering the inertial term. First, the effective electric field, including the ion inertial term of the ion momentum equation, was derived. Subsequently, one-dimensional fluid simulations were conducted. The numerical results were compared with those of one-dimensional particle-in-cell (PIC) simulations. The results of the developed model were similar to those obtained in the case of solving the full-ion momentum equation, as well as more similar to the PIC simulation results than those obtained in the case of the drift-diffusion approximation.
