This paper highlights the utilization of parallel control and adaptive dynamic programming(ADP) for event-triggered robust parallel optimal consensus control(ETRPOC) of uncertain nonlinear continuous-time multiagent systems(MASs).First, the parallel control system, which consists of a virtual control variable and a specific auxiliary variable obtained from the coupled Hamiltonian, allows general systems to be transformed into affine systems. Of interest is the fact that the parallel control technique's introduction provides an unprecedented perspective on eliminating the negative effects of disturbance. Then, an eventtriggered mechanism is adopted to save communication resources while ensuring the system's stability. The coupled HamiltonJacobi(HJ) equation's solution is approximated using a critic neural network(NN), whose weights are updated in response to events. Furthermore, theoretical analysis reveals that the weight estimation error is uniformly ultimately bounded(UUB). Finally,numerical simulations demonstrate the effectiveness of the developed ETRPOC method.

为了探讨苦马豆素通过消化系统对家兔脾脏免疫功能和代谢的影响,将体重为(1.9±0.12)kg的24只家兔随机分成对照组与试验组,每组雌、雄各半。试验组家兔饲喂含有小花棘豆的自制颗粒饲料,饲喂苦马豆素剂量为2 mg/(kg·d),对照组家兔饲喂自制颗粒饲料中不含小花棘豆。所有家兔单笼饲养,自由饮水,每天观测并记录家兔的健康状态。在试验的第60天,采取所有家兔脾脏,对脾脏进行基于iTRAQ的定量蛋白质组学分析、生物信息学分析及关键蛋白质的Western blot验证。结果显示,所有试验组家兔均呈现明显的中毒现象。与对照组相比,共鉴定出315个与新陈代谢(81%)及免疫相关(15%)的差异表达蛋白质(>1.5倍或<1/1.5倍)。而且,苦马豆素中毒家兔脾脏细胞分解代谢处于激活状态,但其免疫反应处于抑制状态。说明苦马豆素抑制了家兔脾脏的免疫功能,激活了脾脏组织的分解代谢。

This paper provides a computer modeling method for the study of nanocrystals. Structural features,such as the boundary component proportion, the reduced density proportion, the excess lattice parameter, and the radial distribution function, have been atomistically simulated. The energy and elastic properties also have been investigated. Simulation results indicate that the structure of grain boundaries in nanocrystals is different from those of the amorphous and the gas, or rather, it is a special structure with some degree of short-range order. Moreover, the structure of crystallites is not entirely the same as that in the perfect crystal lattice. The present simulation method may become one of the foundations of the theoretical study of nanocrystals.
