简介：抑制的安全散布了互连的力量系统的最佳的力量流动(DOPF)被介绍。多区域力量系统的集中的OPF问题被分解成独立DOPF潜水艇问题，为每个区域的。动态安全区域(数据设置就绪)作为限制被包括保证短暂稳定性限制和静态的电压稳定性区域(SVSR)得到限制，和输送管线上电流限制。不同区域的DOPF潜水艇问题的答案通过定价机制被协调直到他们收敛到集中的OPF答案。非线性的DOPF潜水艇问题被预言者修正者内部点方法(PCIPM)解决。IEEE三区域的RTS-96系统被得出以便表明建议方法的有效性。

简介：这篇论文与时间延期和变化时间的参数不确定性在T-S的一个类上集中模糊互连的系统。基于观察员的产量反馈分散了控制器被设计以便靠近环的互连的系统在在为所有可被考虑的不确定性和时间延期的概率的Lyapunov意义是asymptotically稳定的。Sufficientconditions为要用体力地，asymptotically，系统的稳定性以一套线性矩阵不平等(LMI)被给。

简介：jasmonic酸(JA)小径是昆虫folivory导致的主要signal-transduction小径。在jasmonate小径(18:0或16:0-oxylipin线路)影响的变异的植物被学习在在Arabidopsis位于导致的防卫下面的互连的signal-transduction小径上估计JA和它的oxylipin中介12-oxophytodienoic酸(OPDA)和dinor-OPDA(dnOPDA)的效果。我们oxylipinjasmonatesdnOPDA，OPDA和JA举办的数据表演在防卫发信号的不同角色在由咀嚼咬毛虫Pierisrapae喂以后导致了。Jasmonic酸，并且不OPDA或dnOPDA，主要发信号混合物为防卫相关的基因LOX2(Lipoxygenase2)的正式就职被要求，OPR3(12-Oxophytodienoatereductase3)，ACX1(Acyl-CoAoxidase1)并且PAL1(本氨基丙酸ammonia-lyase1)。监视PAL1抄本层次清楚地在P之上显示出JA的那累积。喂的rapae导致水杨酸酸小径的正式就职。而且，JA是为P要求的主要发信号混合物。防卫相关的基因HPL1的导致rapae的表示(Hydroperoxidelyase1)。jasmonatednOPDA也影响HPL分支的正式就职，还它的效果对JA的效果对抗。我们这些jasmonates可以被用来调整Arabidopsis的数据表演导致草食动物的回答以从oxylipin小径的HPL分支。
