The water-soluble conjugated polyelectrolyte, poly[3-（1′-ethyloxy-2′-N- methylimidazole）thiophene]（PEOIMT）, was prepared. Its photophysical and electrochemical properties, and response characteristics to the external condition（e g, temperature response, solvent response and pH response）, were investigated. The results show the PEOIMT belongs to the organic semiconductor. The interaction between the PEOIMT and the bovine serum albumin（BSA） was investigated using UV-vis spectroscopy. It was found that the PEOIMT could interact with the BSA. The PEOIMT can be used as a biosensor to detect the BSA.

Group key distribution is faced with two important problems, i.e. reliability and scalability, to support security multicast for large and dynamic groups. With group member increasing, traditional reliable multicast protocol can not deal with them fully. Gossip-based group key distribution idea for wide-area dissemination was provided. It is based on an gossip-based loss recovery control mechanism. It can provide a probabilistic reliable guarantee for a information dissemination to reach every group member, which can achieve scalability and reliability. To achieve full reliability, three layers protocol model in group key distribution was provided. One is best effect layer, which provides unreliable dissemination. Other is gossip-based loss recovery layer, which provides probabilistic reliable guarantee. Last is vsync-based layer, which provide deterministic loss recovery. We integrate probabilistic loss recovery method with deterministic one. The model possess scalability that probabilistic method has and full reliability prosthesis by vsync-based. To evaluate the effectiveness of gossip technique in scalable and reliable multicast protocols. We have compared gossip protocol with other reliable multicast protocols. Experimental result shows that gossip protocol has better scalability than other.

This paper focuses on investigating immunological principles in designing a multi-agent security architecture for intrusion detection and response in mobile ad hoc networks. In this approach, the immunity-based agents monitor the situation in the network. These agents can take appropriate actions according to the underlying security policies. Specifically, their activities are coordinated in a hierarchical fashion while sensing, communicating, decision and generating responses. Such an agent can learn and adapt to its environment dynamically and can detect both known and unknown intrusions. The proposed intrusion detection architecture is designed to be flexible, extendible, and adaptable that can perform real-time monitoring. This paper provides the conceptual view and a general framework of the proposed system. In the end, the architecture is illustrated by an example to show it can prevent the attack efficiently.

移动adhoc网络由于其动态拓扑、无线信道以及各种资源有限的特点,特别容易遭受拒绝服务(DOS)攻击.提出了移动adhoc网络中一种新的DOS攻击模型———adhocflooding攻击及其防御策略.该攻击主要针对移动adhoc网络中的按需路由协议,如AODV,DSR等.adhocflooding攻击是通过在网络中泛洪发送超量路由查询报文及数据报文,大量地占用网络通信及节点资源,以至于阻塞节点正常的通信.分析adhocflooding攻击之后,提出了两种防御策略:其一是邻居阻止,即当入侵者发送大量路由查询报文时,邻居节点降低对其报文的处理优先级,直至不再接收其报文.其二是路径删除,即目标节点将入侵者发送攻击报文的路径删除,以阻止其继续发送攻击报文.模拟实验证实,通过这两种方法的结合,能够有效地阻止网络中的adhocflooding攻击行为.

Objective: To study the effect of diclofenac suppository in oocyte retrieval of IVF-ET. Study Design: 1176 patients with informed consents were enrolled into this prospective randomized controlled study. The setting was an IVF-ET program at the First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China. According to the analgesic drug use, the patients were randomly divided into pethidine group (573 cases) and diclofenac suppository group (603 cases). The data of vital signs, common adverse reactions, severe adverse events and pain degree in oocyte retrieval were collected. The IVF-ET outcomes were also compared. Results: The post-operation pressure and pulse were lower in pethidine group than in diclofenac suppository group (both P0.001).The rest vital signs were not statistically different (all P>0.05). Common adverse reactions in diclofenac suppository group were relative less (all P0.05). Pain degree between the two groups was not statistically different (P=0.304). IVF-ET outcomes were also not statistically different (all P>0.05). There were 3 cases serious abdominal bleeding with shock in the diclofenac suppository group. Conclusion: Using diclofenac suppository in oocyte retrieval analgesic had a good effect. And there was no adverse effect in the IVF-ET outcome. But we should pay close attention to the probability of serious abdominal bleeding.
