线性时滞动力学问题的精细积分解法

具有时滞的动力系统广泛存在于各工程领域.文中给出了一种新的解决时滞系统动力学的方法———精细积分法,把时滞项看作激励项进行处理,通过对时滞项积分上下限的讨论,采用了线性插值和Romberg积分法对其进行处理.同其它一些方法相比,用精细积分法解决时滞问题具有过程简单、结果精确的优点.     

Respective roles of short-and long-range interactions in protein folding

A new method was presented to discuss the respective roles of short- and long-range interactions in protein folding. It‘s based on an off-lattice model, which is also being called as toy model. Simulated annealing algorithm was used to search its native conformation. When it is applied to analysis proteins lagt and laho, we find that helical segment catmot fold into native conformation without the influence of long-range interactions. That‘s to say that long-range interactions are the main determinants in protein folding.     

Effects of calcineurin on LTP of rats <Emphasis Type="Italic">in vivo</Emphasis>

Calcineurin (CN) is thought to play a role in the synaptic plastivity and long-term potentiation (LTP) in the hippocampus. Based on two LTP models in vivo, a specific inhibitor cyclosporin A (CsA) of CN was observed, which affected LTP in the hippocampal dentate gyrus of the rats. The results indicated that CsA blocked LTP induced by high frequency stimulation (HFS) partly, but it had no effect on the decrease of the onset and peak latency of population spikes (PS) except that it reduced the increase of the amplitude after HFS. On the other hand, CsA blocked LTP induced by ginsenosides (GSS) completely. It suppressed the GSS-enhanced amplitude of PS reversibly and blocked the decrease of the peak latency of PS induced by the GSS. These results suggest that the postsynaptic CN plays a role in the induction of LTP in the hippocampus of the rats.     

论农民家庭承包经营制度的坚持和创新

家庭承包经营是农村的基本经济制度,也是农村制度改革和创新的现实基础。面对农村经济发展的新形势、新任务和新目标,坚持长期稳定家庭承包经营制度的必要性,以及在此基础上正确认识其局限性,推进制度创新和改革是实现农村社会稳定、经济发展必须改解的问题。本从制度基础的角度,在充分肯定家庭承包经营制度合理性的同时,以农村经济发展面临的新的环境条件为背景,分析了这一制度的局限性,提出了以稳定和完善土地承包经营为核心的坚持和创新家庭承包经营制度的一些思路和对策。
