The Complete Proof of the Virial Theorem in the Refined TFD Theory for all Electrons of an Atom in a Solid

The complete proof of the virial theorem in refined Thomas-Fermi-Dirac theory for all electrons of an atom in a solid is given.

An improvement and proof of OGY method

OGY method is the most important method of controlling chaos. It stabilizes a hyperbolic periodic orbit by making small perturbations for a system parameter. This paper improves the method of choosing parameter, and gives a mathematics proof of it.

Proof of solid state cathodoluminescence by using brightness waveform

Three different inorganic-organic hetero-junctions (A : ITO/SiO2/Alq(3)/Al, B: ITO/Alq3/SiO2/Al and C: ITO/SiO2/Alq(3)/ SiO2/Al) were fabricated. The emission can be observed only under positive bias in devices A and B, but under both biases in device C according to their brightness waveforms. With increasing voltage, the increase in blue emission in devices B and C is faster than that in green emission. This is because that the recombination of hot electrons and holes, i.e., electron-hole pairs, produced blue emission in devices B and C, and the recombination of electrons injected from Al with the accumulated holes, which are excited by hot electrons, produced green emission in device A. Hence, the emissions of the devices are attributed to not only the recombination of electrons and accumulated holes, but also the cathodoluminescence-like (CL-like) emission.

Proof of InAs/GaAs self-organized quantum dot lasing and the experimental determination of local Strain effect on the band structures

Confirmation of quantum dot lasing have been given by photoluminescence and electro-luminescence spectra. Energy levels of QD laser are distinctively resolved due to band filling effect, and the lasing energy of quantum dot laser is much lower than quantum well laser. The energy barrier at InAs/GaAs interface due to the built-in strain in self-organized system has been determined experimentally by deep level transient spectroscopy (DLTS). Such barrier has been predicted by previous theories and can be explained by the apexes appeared in the interface between InAs and GaAs caused by strain.

纯公钥模型下对NP语言的高效并发零知识证明系统

提出了一种从3轮公开掷币的对任何NP语言的诚实验证者零知识证明系统到纯公钥模型下4轮f轮最优）对同一语言的具有并发合理性的并发零知识证明系统．该转化方法有如下优点：1）它只引起D（1）（常数个）额外的模指数运算，相比DiCrescenzo等人在ICALP05上提出的需要qn）个额外的模指数运算的转化方法孩系统在效率上有着本质上的提高，而所需的困难性假设不变；2）在离散对数假设下，该转化方法产生一个完美零知识证明系统．注意到DiCrescenzo等人提出的系统只具有计算零知识性质．该转化方法依赖于一个特殊的对承诺中的离散对数的3轮诚实验证者零知识的证明系统．构造了两个基于不同承诺方案的只需要常数个模指数运算的系统这种系统可能有着独立价值．

评一种高效的群签名

群签名是对一般数字签名的一种扩展，有很多重要应用．最近提出的一种高效的群签名，被声称没有采用知识签名，从而签名和验证的计算量远远少于著名的ACJT方案．在本文中，我们指出该方案其实采用了知识签名，但是由于使用上的不当，使得该方案完全不安全，即两个群成员合谋就可以伪造出对任意消息的群签名，且打开算法是无效的．[第一段]

hyo-xtm: a set of hyper-graph operations on xml topic map toward knowledge management

Knowledge management is a critical issue for the next-generation web application, because the next-generation web is becoming a semantic web, a knowledge-intensive network. XML Topic Map (XTM), a new standard, is appearing in this field as one of the structures for the semantic web. It organizes information in a way that can be optimized for navigation. In this paper, a new set of hyper-graph operations on XTM (HyO-XTM) is proposed to manage the distributed knowledge resources.HyO-XTM is based on the XTM hyper-graph model. It is well applied upon XTM to simplify the workload of knowledge management.The application of the XTM hyper-graph operations is demonstrated by the knowledge management system of a consulting firm. HyO-XTM shows the potential to lead the knowledge management to the next-generation web.
