The globus pallidus plays a pivotal role in the basal ganglia circuit. Parkinson's disease is characterized by degeneration of dopamine-producing cells in the substantia nigra, which leads to dopamine deficiency in the brain that subsequently manifests as various motor and non-motor symptoms. This review aims to summarize the involvement of the globus pallidus in both motor and non-motor manifestations of Parkinson's disease. The firing activities of parvalbumin neurons in the medial globus pallidus, including both the firing rate and pattern, exhibit strong correlations with the bradykinesia and rigidity associated with Parkinson's disease. Increased beta oscillations, which are highly correlated with bradykinesia and rigidity, are regulated by the lateral globus pallidus. Furthermore,bradykinesia and rigidity are strongly linked to the loss of dopaminergic projections within the cortical-basal ganglia-thalamocortical loop. Resting tremors are attributed to the transmission of pathological signals from the basal ganglia through the motor cortex to the cerebellum-ventral intermediate nucleus circuit. The cortico–striato–pallidal loop is responsible for mediating pallidi-associated sleep disorders. Medication and deep brain stimulation are the primary therapeutic strategies addressing the globus pallidus in Parkinson's disease. Medication is the primary treatment for motor symptoms in the early stages of Parkinson's disease, while deep brain stimulation has been clinically proven to be effective in alleviating symptoms in patients with advanced Parkinson's disease,particularly for the movement disorders caused by levodopa. Deep brain stimulation targeting the globus pallidus internus can improve motor function in patients with tremordominant and non-tremor-dominant Parkinson's disease, while deep brain stimulation targeting the globus pallidus externus can alter the temporal pattern of neural activity throughout the basal ganglia–thalamus network. Therefore, the comp

论“心即理”视域下翻译学天人合一的意义观

引用

外语学刊 2025年第1期 86-91页

作者：杨镇源电子科技大学外国语学院成都611731

西方翻译学呈现出两种基本意义观:一是在柏拉图主义的笼罩下,将形而上的绝对意义视作完美而不可触及的彼岸,将形而下的相对阐释视作现实却又充满缺憾的此岸,并认为后者只能是对前者的拙劣模仿;二是在解构主义的影响下,将绝对意义和相对... 详细信息

西方翻译学呈现出两种基本意义观:一是在柏拉图主义的笼罩下,将形而上的绝对意义视作完美而不可触及的彼岸,将形而下的相对阐释视作现实却又充满缺憾的此岸,并认为后者只能是对前者的拙劣模仿;二是在解构主义的影响下,将绝对意义和相对阐释同归于虚无。前者以“尊天抑人”的态势陷入天人二分的意义观,在一定程度压抑人本主义精神,后者以“毁天灭人”的态势陷入天人两空的意义观,因而引发虚无主义困境。在新儒家心学思想的“心即理”视域下,翻译学能够走出上述两种思维定势,促使译者立足本心,打通道枢,实现绝对意义和相对阐释的圆融统一,以“顺天应人”的态势成就天人合一的意义观。较之西方翻译学的两种意义观,它不仅凸显译者心性的关键作用,强化人本主义精神,还将本心作为意义的稳固立足点,避免虚无主义困境。这体现出心学思想对于翻译学意义观建构的独特价值,也为中国传统哲学思想在当代翻译学的应用提供了一个值得关注的学术增长点。

IEEE/CAA Journal of Automatica Sinica 2025年第1期 285-287页

作者： Shuo yuan Chengpu Yu Jian Sun the School of Automation Beijing Institute of Technology the Beijing Institute of Technology Chongqing Innovation Center

Dear Editor,This letter studies output consensus problem of heterogeneous linear multiagent systems over directed graphs. A novel adaptive dynamic event-triggered controller is presented based only on the feedback combination of the agent's own state and neighbors' output,which can achieve exponential output consensus through intermittent communication. The controller is obtained by solving two linear matrix equations, and Zeno behavior is excluded.

A dynamic games approach to H∞control design of Do S with application to longitudinal flight control

引用

Science China(Information Sciences) 2015年第9期58卷 171-180页

作者： yuan yuan Department of Mathematics City University of Hong Kong

In this paper, a game theoretic approach to develop H∞ control strategies for the Delta Operator System(Do S) is proposed. Two information patterns for the controller are considered and the conditions are presented in terms of iterative Riccati recursions. By using the delta operator, the calculation stiffness of the discrete system can be circumvented when the sampling frequency is extremely high. The proposed method is applied to the longitudinal flight control of the hypersonic flying vehicle and the effectiveness is verified by the experimental results.
