The central nervous system, information integration center of the body, is mainly composed of neurons and glial cells. The neuron is one of the most basic and important structural and functional units of the central nervous system, with sensory stimulation and excitation conduction functions. Astrocytes and microglia belong to the glial cell family, which is the main source of cytokines and represents the main defense system of the central nervous system. Nerve cells undergo neurotransmission or gliotransmission, which regulates neuronal activity via the ion channels, receptors, or transporters expressed on nerve cell membranes. Ion channels, composed of large transmembrane proteins, play crucial roles in maintaining nerve cell homeostasis. These channels are also important for control of the membrane potential and in the secretion of neurotransmitters. A variety of cellular functions and life activities, including functional regulation of the central nervous system, the generation and conduction of nerve excitation, the occurrence of receptor potential, heart pulsation, smooth muscle peristalsis, skeletal muscle contraction, and hormone secretion, are closely related to ion channels associated with passive transmembrane transport. Two types of ion channels in the central nervous system, potassium channels and calcium channels, are closely related to various neurological disorders, including Alzheimer's disease, Parkinson's disease, and epilepsy. Accordingly, various drugs that can affect these ion channels have been explored deeply to provide new directions for the treatment of these neurological disorders. In this review, we focus on the functions of potassium and calcium ion channels in different nerve cells and their involvement in neurological disorders such as Parkinson's disease, Alzheimer's disease, depression, epilepsy, autism, and rare disorders. We also describe several clinical drugs that target potassium or calcium channels in nerve cells and could be u

对在无线局域网环境下,基于UDP的多媒体流码率自适应控制进行了研究,同时探讨了网络自相似等相关问题,并借鉴通信原理中的自适应滤波方法,解决网络较平稳时码率收敛问题。通过在实验环境下对理论结果加以测试验证,实现了在自相似、多级分形的无线网络状况下,RTP/UDP/IP协议的多媒体码率自适应控制。该方案能更有效地跟踪实时的网络有效带宽,比传统模型的方案更快速、准确,保证服务质量。特别地,采用带收敛特性的自适应算法后,当网络有效带宽趋于稳定时,媒体流的输出速率也收敛并趋于稳定,有利于server和网络效率的改善。

刘禹锡的诗文很早就在汉文化圈内具备广泛影响,古代朝鲜半岛的文人对其经典作品十分熟悉,也留下不少学习模仿之作。但较之于他的诗文作品,刘禹锡在朝鲜士人眼中,更典型的意义是作为一位贬谪诗人存在着。受儒家孝友之道,以及唐宋以来中国文人及史学家既有观念的影响,朝鲜士人对刘禹锡的政品与人品大多持批评与否定的态度,但也有少数文人借助拟作的特殊形式,将自身的贬谪境遇与情怀,寄寓于对刘禹锡才华人品的认同与理解中,并进而成为刘禹锡以及中国贬谪诗人的异域知音。
