Vagus nerve stimulation in intracerebral hemorrhage:the need for further research

Neural Regeneration Research 2025年第11期20卷 3213-3214页

Vagus nerve stimulation(VNS)and stroke:Stroke is the second leading cause of death and the third leading cause of disability worldwide(Baig et al.,2023).There have been significant paradigm shifts in the management of acute ischemic stroke through mechanical *** chronic ischemic stroke,invasive VNS paired with rehabilitation is associated with a significant increase in upper limb motor recovery and is FDA-approved(Baig et al.,2023).There are no treatments of similar efficacy in acute intracerebral hemorrhage(ICH)where several promising trials,e.g.,TICH-2,STOP-AUST,and TRAIGe did not show improvements in functional outcomes(Puy et al.,2023).

Schamel equation in an inhomogeneous magnetized sheared flow plasma with q-nonextensive trapped electrons

引用

Chinese Physics B 2018年第2期27卷 428-434页

作者： Shaukat ali shan Qamar-ul-Haque Theoretical Physics Division (TPD) PINSTECH

An investigation is carried out for understanding the properties of ion–acoustic（IA） solitary waves in an inhomogeneous magnetized electron-ion plasma with field-aligned sheared flow under the impact of q-nonextensive trapped electrons. The Schamel equation and its stationary solution in the form of solitary waves are obtained for this inhomogeneous plasma. It is shown that the amplitude of IA solitary waves increases with higher trapping efficiency（β）, while the width remains almost the same. Further, it is found that the amplitude of the solitary waves decreases with enhanced normalized drift speed, shear flow parameter and the population of the energetic particles. The size of the nonlinear solitary structures is calculated to be a few hundred meters and it is pointed out that the present results are useful to understand the solar wind plasma.

A unified approach to output synchronization of heterogeneous multi-agent systems via L2-gain design

引用

Control Theory and Technology 2017年第4期15卷 340-353页

作者： shan Zuo Yongduan Song Hamidreza Modares Frank L. Lewis ali Davoudi 1. School of Automation engineering University of Electronic Science and Technology of China Chengdu Sichuan 611731 China 2. The University of Texas at Arlington Research Institute Fort Worth TX 76118 U.S.A.

In this paper, a unified design procedure is given for output synchronization of heterogeneous multi-agent systems （MAS） on communication graph topologies, using relative output measurements from neighbors. Three different control protocols, namely, full-state feedback, static output-feedback, and dynamic output-feedback, are designed for output synchronization. It is seen that a unified design procedure for heterogeneous MAS can be given by formulation and solution of a suitable local L2-gain design problem. Sufficient conditions are developed in terms of stabilizing the local agents＇ dynamics, satisfying a certain small-gain criterion, and solving the output regulator equations. Local design procedures are presented for each agent to guarantee that these sufficient conditions are satisfied. The proposed control protocols require only one copy of the leader＇s dynamics in the compensator, regardless of the dimensions of the outputs. This results in lower-dimensional compensators for systems with high-order outputs, compared to the p-copy internal model approach. All three proposed control protocols are verified using numerical simulations.
