Multiple sclerosis(MS)is an autoimmune disorder of the central nervous system(CNS)and is primarily characterized by immune cell infiltration leading to relapses followed by remission phases and a disease course turning progressive over time with neurodegenerative processes taking over(Amin and Hersh,2023).Of note,beyond relapse-associated worsening early in disease progression independent of relapse activity may arise independently of relapse activity and can occur in all ***-mediated damage of myelin sheaths and the subsequent loss of mature oligodendrocytes are resulting in impaired axonal integrity,neurodegeneration and accounts for irreversible neuronal damage(Kuhlmann et al.,2023).The current landscape of available disease-modifying therapies comprises mainly immunomodulatory drugs that effectively diminish relapses and slow down progression at the onset form of the disease,namely relapsing MS(RMS).In this regard,a number of drugs have been approved as disease-modifying therapies for MS by US Food and Drug Administration and European Medicines Agencies(Box 1).

针对冬季渡槽的湿热全耦合效应问题,避免渡槽在冬季输水过程中出现裂缝现象,以寒旱地区引洮工程柳林沟渡槽为工程背景,利用湿热耦合传输理论分析,实测2023年1月5—20日的环境温度、环境湿度及风速,采用Fluent有限元软件建立了不同环境参数的混凝土箱形渡槽温度场、湿度场、湿热耦合场有限元模型,并分析不同工况对冬季渡槽的非耦合和全耦合状态下的变形影响。分析结果表明,渡槽通水时冬季最不利温差为-14.7℃,不通水时为-6.3℃;渡槽通水时冬季最不利横向温差为-10.2℃,不通水时为-6.2℃;在湿度扩散过程中,沿板厚方向湿度由内向外逐渐减小,且吸水速度随时间的增大而减小;在湿热耦合过程中,全耦合场温度值小于非耦合场温度值,湿热全耦合作用的挠度变化值小于湿热非耦合作用下的挠度变化值,湿热耦合作用的拉应力小于湿热非耦合作用下的拉应力值,因此,湿热全耦合作用对渡槽结构变形有利。
