The Relationship Between Inflammation and Central Nervous System in Multiple Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Aim Multiple sclerosis is an autoimmune demyelination disease that is seen especially in the young population and has a progressive course, causing motor, sensory, and cognitive deficits. In the literature, the pathogenesis of MS disease and the interconnection between the immune and central nervous system in the disease have not been fully ...

Dizhen xuebao在分析场地条件对地震震害影响及国内外关于软弱土层对场地地震反应影响的基础上，采用实际含淤泥质土层场地资料，建立了12个含软弱土层的场地模型，在不同输入地震动水平下进行了场地地震反应一维等效线性化分析，讨论了软弱土层厚度和埋深对场地地震反应的影响。结果表明：随着软弱土层的埋深或厚度的增加，反应谱特征周期逐渐增大；输入地震动峰值增加，反应谱特征周期亦增大。继而依据软弱土层厚度、埋深及输入地震动强度对场地加速度反应谱特征周期的影响特征，提出了含软弱土层场地地震动加速度反应谱特征周期调整方法。

On Ground Motion Intensity Indices
Earthquake Spectra, 2007 The characterization of strength of earthquake demands for seismic analysis or design requires the specification of a level of intensity. Numerous ground motion intensity indices that have been proposed over the years are being used for normalizing or scaling earthquake records regardless of their efficiency. An essential point of this study is that a

Higher Amyloid and Tau Burden Is Associated With Faster Decline on a Digital Cognitive Test
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective A 2‐min digital clock‐drawing test (DCTclock) captures more granular features of the clock‐drawing process than the pencil‐and‐paper clock‐drawing test, revealing more subtle deficits at the preclinical stage of Alzheimer's disease (AD). A previous cross‐sectional study demonstrated that worse DCTclock performance was associated with

Dizhen xuebao地震动特性受到地震震源、地震波传播介质和局部场地条件等因素的综合影响，虽然地震动反应谱虽然具有统计意义上的共性，但其具体形状又各不相同，特别是部分加速度反应谱与统计平均值之间存在显著的规律性偏差。为了进一步探究加速度反应谱与统计平均值之间的规律性偏差，本文基于日本KiK-net台网获取的8万余条强震动记录，建立了考虑地震震级和震中距影响的地面峰值加速度归一化加速度反应谱，并以预测值＋0.5倍方差为界将加速度反应谱分为有、无反应谱规律性偏差的两组。通过有反应谱规律性偏差的反应谱（观测值 ...

Nonstationary Stochastic Simulation of Strong Ground-Motion Time Histories : Application to the Japanese Database [PDF]
, 2012 For earthquake-resistant design, engineering seismologists employ time-history analysis for nonlinear simulations. The nonstationary stochastic method previously developed by Pousse et al. (2006) has been updated.

Lessons Learned: Quality Analysis of Optical Coherence Tomography in Neuromyelitis Optica
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Introduction Optical coherence tomography (OCT)‐derived retina measurements are markers for neuroaxonal visual pathway status. High‐quality OCT scans are essential for reliable measurements, but their acquisition is particularly challenging in eyes with severe visual impairment, as often observed in neuromyelitis optica spectrum disorders ...

Network Localization of Fatigue in Multiple Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Fatigue is among the most common symptoms and one of the main factors determining the quality of life in multiple sclerosis (MS). However, the neurobiological mechanisms underlying fatigue are not fully understood. Here we studied lesion locations and their connections in individuals with MS, aiming to identify brain networks ...
