Two multiparty simultaneous quantum identity authentication (MSQIA) protocols based on secret sharing are presented. All the users can be authenticated by a trusted third party (TTP) simultaneously. In the first protocol,the TTP shares a random key K with all the users using quantum secret sharing. The ith share acts as the authentication key of the ith user. When it is necessary to perform MSQIA,the TTP generates a random number R secretly and sends a sequence of single photons encoded with K and R to all the users. According to his share,each user performs the corresponding unitary operations on the single photon sequence sequentially. At last,the TTP can judge whether the impersonator exists. The sec-ond protocol is a modified version with a circular structure. The two protocols can be efficiently used for MSQIA in a network. They are feasible with current technol-ogy.

Brief Review on PACS Development Overseas

Study on Syntheses and Characterizations of Polymethylphenethylsilane, Polymethylcyclohexylsilane and their Copolymers

自主创新与持续增长第十一届中国科协年会

作者： GAO Shan 1,ZHANG Huixiong 1,ZHANG Yongkang 2 (1.School of Life Science and Technology,University of Electronic Science and Technology of china (UESTC),chengdu 61005.,sichuan,china 2.college of {5. engineering,chengdu University of Technology,chengdu 610059,sichuan,china)

This paper is a brief review on PACS development overseas. The question we focused on is why PACS have not developed rapidly in every part of the world as experts’ expectation during its more than 20 years’ history. The following four topics are touched, 1) imbalance in PACS development, 2) challenges in PACS training;3)distributed or centralized PACS, and 4)future of PACS.

The effects of adding cosolvents of diglyme and 15.crown-5.to the reaction mixture of Wurtz-type coupling of dichlorosilanes on the yield and relative molecular mass dispersity of polymethylphenethylsilane(PMPES) were discussed. The results show that addition of 10%(volume ratio of diglyme to toluene) diglyme as a cosolvent to the reaction mixture leads to the yield increase of PMPES with a monomodal distribution of relative molecular masses. Adding 10%diglyme to the reaction mixtures, the yields of polymethylcyclohexylsilane(PMCS) and copolymers (polymethylphenethylsilane-co-methylcyclohexylsilane), (the molar ratios of methylphenethyldichlorosilane to methylcyclohexyldichlorosilane were 2.0, 1.0 and 0.5. and the copolymers were abbreviated by Copolymers I, II, III, respectively) are 47%, 5.%, 5.%, 5.%, respectively. Their relative molecular masses ([`(M)]w )(\bar M_w ) almost reach 105. These polysilanes were characterized by 1H-NMR, IR and UV absorption spectrum.

An Improved Algorithm of Image Edge Detection Based on Grey Prediction Model

2009 3rd IEEE International Symposium on Microwave,Antenna,Propagation and EMC Technologies for Wireless Communications

作者： Liu Kun Electronic engineering college chengdu University of information Technology chengdu {5.

A new accelerated method for Time-Domain Finite Element Method （TD-FEM） is presented. As the number of triangular elements mount up, compare with a Central Processing Unit （CPU） of comparable technology generation, the speed of Graphics Processor Unit （GPU） is faster and faster. Its properties make the off-the-shelf GPU suitable for accelerating TD-FEM simulations.

作者： He Tong-Li Math Department chengdu Institute of information engineering chengdu , china Gan Jian-Hong {5. of Software engineering chengdu Institute of information engineering chengdu , china

With conventional edge detection algorithms, the shortcomings of undetected and artificial information will happen. An improved method based on grey prediction model is proposed to improve the performance of image edge detection considerably, and the corresponding experiments is carried out. The results show that the algorithm can effectively detect the edge of images, while retaining more vivid image details, comparing to the traditional algorithm。 This electronic document is a "live" template. The various components of your paper [title, text, heads, etc.] are already defined on the style sheet, as illustrated by the portions given in this document.

Ca（NO3）2·4H2O, Eu（NO3）3 and H2C2O4·2H2O were adopted to synthesize CaO： Eu3＋ with the chemical co-precipitation method, and the effects of the calcination temperature and Eu3＋ doping concentration on the phosphor structure and its luminescent properties were investigated by TG-SDTA, XRD, and PL-PLE. The results confirm that the Eu3＋ ions as luminescent centers substi-tutes Ca2＋ sites without changing the crystal structure of cubic CaO. The optimum calcination tem-perature and the optimum concentration of Eu3＋ are 1 100 ℃ and 1 mol%, respectively, under which the best crystallinity and highest PL intensity appeared. The maximum emission wavelength is 5.2 nm （5.0→7F1） which is excited by xenon lamp with the wavelength of 200-280 nm, indicating that the Eu3＋ ion mainly locates in the symmetric position （Oh） in the crystal lattice of CaO.

The isotope shifts（TSs） for the 2s2S（1/2） to 2p2PJ（J = 1/2,3/2） transitions of the lithium nuclei including the stable and short-lived isotopes are calculated based on the multi-configuration Dirac-Hartree-Fock method and the relativistic configuration interaction *** results are in good agreement with the previous theoretical and experimental results within a deviation less than 0.05..The methods used here could be applied to the IS calculations for other heavier Li-like ions and few-electron systems.
