Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective In multiple sclerosis, the optimal time for deploying a therapeutic intervention is before the central nervous system is damaged; given the success of trials treating the earliest stage of MS, the radiologically isolated syndrome, developing primary prevention strategies is an important next challenge.

Dizhen xuebao本文开展了基于地震活动图像预测华北地区地震的机器学习方法研究。根据华北地区M≥5.0中强震、强震及大震的地震平均时间间隔，采用1970年以来华北地区M≥5.0中强震、强震及大震震前大量不同时窗长的ML≥3.0地震活动图像作为输入数据集，提出了基于地震活动图像预测地震的机器学习方法，并进行了震例回溯。利用本文提出的方法选取“未拓展图像数据集”和“含拓展图像数据集”对华北地区发生中强地震进行预测对比，结果显示，数据集样本量的增加有利于提高地震预测模型的精度，其中“含拓展图像数据集”预测地震的准确率可达77%；

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Stereoelectroencephalography‐guided radiofrequency thermocoagulation (SEEG‐RFTC) has emerged as a safe and effective minimally invasive treatment for children with drug‐resistant focal epilepsy. Although evidence from real‐world studies remains limited, numerous pediatric cases have demonstrated promising outcomes. This retrospective

Dizhen xuebao为探讨华北地区飑线天气对深井水位干扰的特征和影响机制，以2017年9月21日发生在华北中部的一次飑线事件为例，使用时频分析和线性回归等方法系统地诊断了此次飑线对无极、辛集、永清和宁晋等四口千米级深井的水位扰动特征。结果表明：在宏观层面，飑线过境各深井时会引起气压快速涌升，在气压的激励下，深井水位出现了即时的脉冲状波动，该干扰的持续时间可长达127 min；此次飑线过程中周期性气压波动的主频段为15—25 cpd，在该频段内，各深井水位与气压扰动的形态高度负相关，相关系数均低于−0.95 ...

Arthritis Care &Research, EarlyView.Objective Ultrasound (US) has been proposed as a potential tool for assessing skin fibrosis in systemic sclerosis (SSc). However, a large‐scale comparison of US‐based assessment with histologic markers of skin fibrosis has not been reported. We evaluated US‐based skin assessments for their face validity (differentiation between involved SSc and healthy

Dizhen xuebao华北地区作为内陆典型的伸展断陷区和强震活动区，在东部太平洋俯冲和西部印度大陆碰撞的双重构造作用和地下水过量开采的背景下，其垂直形变特征表现为明显的区域差异。为定量分析华北地区现今的地壳垂直形变特征，对收集整理的1406个GNSS站点1999—2019年长达二十年的GPS观测资料进行统一的高精度处理，获取了该地区高空间分辨率的垂向形变速度场。结果显示：华北平原、淮河平原和大别山以南区域以沉降为主，其中华北平原和淮河平原的最大沉降速率分别约为70 mm/a和50 mm/a；太行山、吕梁山、苏鲁造山带 ...

Large shift in symbiont assemblage in the invasive red turpentine beetle.
PLoS ONE, 2013 Changes in symbiont assemblages can affect the success and impact of invasive species, and may provide knowledge regarding the invasion histories of their vectors. Bark beetle symbioses are ideal systems to study changes in symbiont assemblages resulting
