In this paper, the convergence behaviors are considered for a class of high-order fuzzy cellular neural networks with time-varying *** sufficient conditions are established to ensure that all solutions of the networks converge to zero point. Compared with some earlier works, the new criteria do not require the Lipschitz continuous condition on activation functions and the differentiability of variable delays. Finally, an example with numerical simulation is given to show the effectiveness of the proposed method and results.

作者： liao huimin CHONG Lian'e TAN Li CHEN Xiaodan YOU Rui GONG Ping Key Laboratory of Structure-Based Drug Design and Discovery Ministry of Education Shenyang Pharmaceutical University Shenyang 110016 P. R. China

A series of novel 5,7-diphenylimidazo[1,2-a]pyridine derivatives was designed and synthesized. The in vitro cytotoxic activities of all the target compounds against human colorectal cancer（HT-29）, human lung can- cer（H460）, human gastric cancer（MKN45） and human breast cancer（MDA-MB-231） cell lines were evaluated. The pharmacological results indicated that most of the target compounds showed moderate to excellent activities against the tested cell lines. The most promising compound 4h（0.20, 0.006, 0.08, 0.021 μmol/L） was 2.6, 5.1, 3.6 and 21.9 times more active than EPC2407（0.52, 0.031, 0.29, 0.46 μmol/L） against HT-29, H460, MKN45 and MDA-MB-231 cell lines, respectively.

研究了带有区间时滞的不确定系统的稳定性问题。通过采用时滞分割法,把时滞区间分割成任意两小段,并构造恰当的Lyapunov函数,利用积分不等式,得到了新的时滞相关的稳定性准则。通过数值例子验证了结果的有效性。
