Quantum Games of Continuous Distributed Incomplete Information

We study two-player quantum games of incomplete information in which both the sides have partial information.The previous results of Du et al. [Phys. Rev. E 68 (2003) 016124] are incorporated in our more general formalism.Because of different roles played by the total information uncertainty and the information asymmetry, the game exhibits many interesting features.     

关于Banach空间中凸泛函的广义次梯度不等式

本文在前人^[1,2]的基础之上，以凸泛函的次梯度不等式为工具，将Jensen不等式推广到Banach空间中的凸泛函，导出了Banach空间中的Bochner积分型的广义Jensen不等式，给出其在Banach空间概率论中某些应用，从而推广了文献[3—6]的工作．     

流动注射化学发光法测定甲磺酸双氢麦角毒碱

磺酸双氢麦角毒碱(Co-dergocrine mesvlate,Hydergine)又名喜得镇、舒脑宁,我国将其列为国家基本药物.目前,测定甲磺酸双氢麦角毒碱的分析方法,主要有荧光分光光度法、可见紫外分光光度法、免疫分析法,但未见文献报道过化学发光法测定甲磺酸双氢麦角毒碱的研究.作者发现,在碱性条件下,过氧化氢直接氧化甲磺酸双氢麦角毒碱不会产生化学发光,但当高碘酸钾和甲磺酸双氢麦角毒碱混合反应后,再加过氧化氢氧化会产生较强的化学发光,且发光强度与甲磺酸双氢麦角毒碱的浓度在一定范围内有良好的线性关系,据此建立了流动注射化学发光测定甲磺酸双氢麦角毒碱的新体系.     

双瓶输液中的数理问题

医学上常用吊瓶式输液器给病人输液 ,而且往往是双瓶串起来进行 .在输液的过程中 ,涉及到许多中学数学和物理的知识 ,下面是笔者在研究性学习中 ,讨论的一个数理问题 .图 1　双瓶输液图例 1　如果我们将Ａ瓶内装入普通盐水 ,Ｂ瓶内装入药液 ,在两瓶如图 1连接情况下输液 ,那么 ,药液先从Ｂ瓶下面连接的软管中流入Ａ瓶中 ,经混合后 ,液体再从Ａ瓶下面的针管中流出 ,结果是Ｂ瓶内液体先流完 .试问 :当Ｂ瓶内液体流完时 ,从Ａ瓶下面流出的液体浓度为多少 ?解析　为了使问题简化 ,我们假设Ａ瓶内的液体是没有溶质的液体 ,Ｂ瓶内的液体全部是溶质…     

中微子物理若干前沿问题

 在过去的几年间,大量的实验结果已经表明中微子有非零质量以及轻子味混合。这一进展为我们打开了一个全新的值得探索的基本粒子世界。关于中微子我们已经知道了多少,我们想要发现什么?本文将从理论与唯象的观点进行阐述。目前中微子物理的前沿问题主要包括:中微子真的发生味转化吗?有几代中微子?存在惰性中微子吗?中微子的质量是多少?中微子是马约拉纳粒子还是狄拉克粒子?轻子味混合矩阵的混合角有多大?轻子味混合矩阵包含CP破坏位相吗?如果包含,那么在中微子振荡和无中微子双β衰变中,这些位相会导致可探测的CP破坏效应吗?     

Novel Chiral Ferrocenyl Aziridino Alcohol Catalysts Promoting Asymmetric Addition of Diethylzinc to Aldehydes

Optically active aziridino alcohols containing ferrocenyl groups were prepared from commercially available L-threonine in excellent yields and used as catalysts to promote the asymmetric addition of diethylzinc to aryaldehydes to afford 1-arylpropanol in up to 84% enantiomeric excesses with moderate to good yields.     

Studies on the Adsorption of Asymmetrical Triblock Copolymers by Scheutjens-Fleer Theory and Monte Carlo Simulation

The adsorption of asymmetrical triblock copolymers from a non-selective solvent on solid surface has been studied by using Scheutjens-Fleer mean-field theory and Monte Carlo simulation method on lattice model. The main aim of this paper is to provide detailed computer simulation data, taking A8-kB20Ak as a key example, to study the influence of the structure of copolymer on adsorption behavior and make a comparison between MC and SF results. The simulated results show that the size distribution of various configurations and density-profile are dependent on molecular structure and adsorption energy. The molecular structure will lead to diversity of adsorption behavior. This discrepancy between different structures would be enlarged for the surface coverage and adsorption amount with increasing of the adsorption energy. The surface coverage and the adsorption amount as well as the bound fraction will become larger as symmetry of the molecular structure becomes gradually worse. The adsorption layer becomes thicker with increasing of symmetry of the molecule when adsorption energy is smaller but it becomes thinner when adsorption energy is higher. It is shown that SF theory can reproduce the adsorption behavior of asymmetrical triblock copolymers. However, systematic discrepancy between the theory and simulation still exists.The approximations inherited in the mean-filed theory such as random mixing and the allowance of direct back folding may be responsible for those deviations.
