This paper primarily discusses the leader-following consensus problem in nonlinear second-order multi-agent systems with nonidentical nodes. Sampled-data-based protocols are applied to reach *** delay-free and input-delay protocols are proposed. Based on the Lyapunov functional approach and linear matrix inequality(LMI) method, sufficient criteria are obtained to guarantee quasi-consensus for nonlinear heterogeneous multi-agent systems. All the heterogeneous followers can track the leader within a bounded range. Furthermore, the error systems between the leader and each follower eventually converge to a convergence domain that depends on the heterogeneity among the dynamics of the agents. Additionally,leader-following consensus can also be reached as the heterogeneity vanishes. Finally, numerical simulations are provided to illustrate the theoretical results.

Synchronization is one of the most important dynamics in neural networks. Several scholars have studied the quasi-synchronization of heterogeneous neural networks [1],wherein external controllers play a significant role. Impulsive control, a kind of energy-saving control, is activated instantaneously only at specific discrete moments.

The suppression rates of MPA for HBsAg andHBeAg at a concentration of 50 μg/ml were 34.2% and 24.1% respectively. The expression of HBVDNA was only 49% as compared with controls when treated with MPA at a concentration of 50 μg/***: Mycophenolate acid can suppress the expression of HBsAg and HBeAg as well as thereplication of HBV DNA in the 2.2.15 cell. The suppressive degree is dose-dependent.

Hepatobiliary & Pancreatic Diseases International 2004年第2期3卷 235-240页

作者： Hao Zhang Shu-Sen Zheng guo-ping jiang Li-Hua Wu Fen Zhu Zhen-Lin Yang Department of Hepatobiliary Surgery First Affiliated Hospital Zhejiang University School of Medicine Hangzhou 310003 China. haozh@***

BACKGROUND: Important advances have made within the past few years in the treatment of hepatocellular carcinoma (HCC), however, the long-term prognosis after resection of HCC remains unsatisfactory as a result of a high incidence of recurrence. This study was to investigate immunization with fusions of DCs and HCC cells against HCC tumors transplanted to mice.METHODS: Fusion cells of dendritic cells (DCs) and H22 cells were prepared with polyethylene glycol. Expression of MHC and costimulatory molecules by dendritomas were determined by FACs. To study the antitumor immune preventitive and therapeutic effects, fusions were subcutaneously injected into naive or tumor-bearing mice; the CTL activity was assumed by the LDH method, and the expression of tumour necrosis factor-alpha (TNF-alpha) and interferon-gamma(IFN-gamma) in tumors were assayed by reverse transcription-polymerase chain reaction (RT-PCR).RESULTS: The hybridomas of DCs and H22 cells acquired both DCs and H22 cells phenotypes. Immunization of BALB/C mice with DC/H22 fusions induced protective immunity against a high dose of H22 tumor challenge. After treatment with hybridomas, the survival time of tumor-bearing mice was extended. The expression level of TNF-alpha and IFN-gamma mRNA was markedly increased.CONCLUSION: The hybridomas of DCs and H22 cells could induce effective antitumor immune responses and may be potentially used in prevention and management of recurrence and metastasis of HCC.

Feasibility of Localizing in vivo Micro-devices with Electromagnetic Methods

引用

Journal of Shanghai Jiaotong university(Science) 2008年第5期13卷 559-561页

作者：郭旭东颜国正姜萍萍 School of Electronic Information and Electrical Engineering Shanghai Jiaotong University

In order to measure the location of medical micro-devices in the gastrointestinal tract, electro-magnetic methods were developed considering the magnetic permeability of human bodies. Two varieties of electromagnetic localization methods have been implemented: one uses direct current(DC) to generate the elec-tromagnetic field, and the other uses alternating current (AC). The two varieties of the localization principle were analyzed and relevant experiments were made. The experiments show that the alternating electromagnetic method acquires higher accuracy, higher stability and wider measurement range.
