Entanglement spectrum: Identification of the transition from vortex-liquid to vortex-lattice state in a weakly interacting rotating Bose-Einstein condensate
Zhao Liu,Hong-Li Guo,Vlatko Vedral,Heng Fan
Physics , 2010, DOI: 10.1103/PhysRevA.83.013620
Abstract: We use entanglement to investigate the transition from vortex liquid phase to vortex lattice phase in weakly interacting rotating Bose-Einstein condensate (BEC). Ground state entanglement spectrum is analyzed to distinguish these two different phases. For the torus geometry, the low-lying part of ground state entanglement spectrum, as well as the behavior of its lowest level change clearly when the transition occurs. For the sphere geometry, the disappearance of entanglement gap in the conformal limit (CL) can indicate this transition. We also show that the decrease of entanglement between particles can be regarded as a signal of the transition.
A function cascade synchronization method with unknown parameters and applications

An Hong-Li,

物理学报 , 2008,
Abstract: This paper investigates the function cascade synchronization of chaos system. Combining cascade synchronization scheme, parametric adaptive control and projective synchronization scheme, it proposes a new function cascade synchronization scheme to address a generalized-type synchronization problem of three famous chaotic systems: the Lorenz system, Liu system and R\"{o}ssler system, the states of two identical chaotic systems with unknown parameters can be asymptotically synchronized by choosing different special suitable error functions. Numerical simulations are used to verify the effectiveness of the proposed synchronization techniques.

Abstract: Objective: To investigate the effects of traditional Chinese compound recipe Yiqi Zengmin (YQZM) formula on expression of glucose transporter 4 (GLUT4) in skeletal muscle of rats with type 2 diabetes induced by high-fat diet combined with low-dose-streptozotocin injection.Methods: Fifty male rats were randomly divided into two groups: model group fed with high-fat diet (n=40) and control group (n=10). After 4-week feed of high-fat diet, the rats of the model group were injected with streptozotocin at a dose of 35 mg/kg. Rats with plasma glucose over 16.67 mmol/L were randomly divided into 4 groups: diabetic model group, YQZM group, rosiglitazone group and losartan group and were treated with water, YQZM, rosiglitazone or losartan respectively by oral administration for 8 weeks. The expression of GLUT4 protein in the cytoplasm and the plasma membrane of isolated rats’ skeletal muscles were detected by Western blotting.Results: The expression of GLUT4 in the plasma membrane was more than that in the cytoplasm in skeletal muscle tissues of the normal rats, while the expression of GLUT-4 in the plasma membrane was less than that in the cytoplasm in skeletal muscle tissues of the type 2 diabetic rats. YQZM formula enhanced GLUT4 translocation from the cytoplasm to the plasma membrane in skeletal muscle tissues, similar to rosiglitazone.Conclusion: YQZM formula can enhance GLUT4 translocation from the cytoplasm to the plasma membrane in skeletal muscle tissues, and displays the insulin sensitization characteristic of rosiglitazone.

Application of Rayleigh Quotient-Desampling FIR Filter in Passive Location System Using the FM Broadcast Signals

ZHAO Hong-li,Wu Tie-ping,Bao Zheng,

电子与信息学报 , 2005,
Abstract: According to the characteristic of coherent pulse compression in the passive location system using the FM broadcast signals, the desampling FIR filter is necessary and feasible. The maximum of SNR after coherent pulse compression is defined as the proper criterion for the design of the desampling filter. The relation of the SNR and the coefficients of the filter adopted is deduced. The steps by the Rayleigh quotient method to obtain the optimal desampling FIR filter are also presented. The results of simulation show that the proposed method achieves good SNR despite its low computation complexity.
Efficient pairing-based and identity-based generalized signcryption scheme

ZHANG Hong-li,ZHAO Jing,LIU Wen-yuan,

计算机应用研究 , 2010,
Abstract: To improve the efficience, this paper proposed a new efficient identity-based generalized signcryption scheme using the bilinear pairings and the ideas of generalization. Proved the proposed scheme to be message confidentiality non-repudiation and unforgeability under the random oracle model. As compared with the only-one identity-based gernalized signcryption scheme to date,the proposed scheme decreases two pairing operations, and is more efficient.
Improvement of YBCO Film Properties by Twostep Deposition Using Spray Pyrolysis Method
LIU Min,SUO Hong-Li,ZHAO Yue,ZHANG Ying-Xiao,LIU Dan-Min,ZHOU Mei-Ling
无机材料学报 , 2007, DOI: 10.3724/sp.j.1077.2007.00377
Abstract: The YBCO films were directly deposited on the {110} <011> textured Ag substrates by an ultrasonic spray pyrolysis method using the modified device. The YBCO film made by one step deposition at 900 n textured Ag substrate has a weak in lane texture and low Jc value. The observed white points in this film consist of high content of Ag on the surface of this film, which are due to the vaporization and diffusion of Ag atoms at high deposition temperatures. While the performance of YBCO films can be significantly enhanced by using twostep deposition route, firstly predepositing the precursor film at 700 hen carrying out the second step depositing at 900 he results show that the two-step deposition can effectively prevent Ag atoms from vaporizing and diffusing into YBCO films and improve the surface roughness, texture and superconducting properties of YBCO films. The YBCO film being 15cm long, coated on {110}<011> textured Ag tape by this two-step deposition method exhibits a transport Jc value of more than 104A/cm2 at 77K.
