单峰式加速度反应谱规律性偏差统计研究

Dizhen xuebao
强震动记录显示，加速度反应谱普遍存在幅值大、宽度小的窄峰，这在现有地震动衰减关系（强震动预测方程）未能予以充分呈现。基于日本KiK-net台网近二十万条强震动记录，采用高斯曲线对单峰式加速度反应谱规律性偏差进行了拟合，利用高度、中心周期、宽度等三个参数对单峰式加速度反应谱规律性偏差予以参数化表征，分析了多个地震动、场地条件表征参数与这三个参数间的相关性，并据此建立了单峰式加速度反应谱规律性偏差的经验预测模型。分析结果表明，所建立的单峰式加速度反应谱规律性偏差经验预测模型 ...

Adaptive Spectral Feature Forecasting for Diffusion Sampling Acceleration

CoRR
Diffusion models have become the dominant tool for high-fidelity image and video generation, yet are critically bottlenecked by their inference speed due to the numerous iterative passes of Diffusion Transformers. To reduce the exhaustive compute, recent works resort to the feature caching and reusing scheme that skips network evaluations at selected ...

Efficacy of Inebilizumab in N‐MOmentum Trial Participants With or Without Prior Immunosuppressants

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This post hoc analysis examined the impact of prior immunosuppressants on the long‐term efficacy and safety of inebilizumab, a cluster of differentiation 19+ B‐cell–depleting monoclonal antibody, in participants with aquaporin‐4–seropositive neuromyelitis optica spectrum disorder from the N‐MOmentum trial (NTC02200770).

基于日本强震动记录的不同分类场地加速度反应谱衰减关系统计分析

Dizhen xuebao
首先利用日本强震动观测台网KiK-net的646个台站的场地钻孔资料和2万5 275对水平向强震动记录，根据中、美、日三国抗震设计规范的场地分类方法分别对所选台站场地进行分类，并按此场地分类结果对强震动观测记录进行归类分组，形成了12个强震动记录数据集；然后，计算每一记录的加速度反应谱（包括峰值加速度反应谱），并针对每一强震动记录的加速度反应谱数据集进行统计分析，得到了三种场地分类方法的12类场地的加速度反应谱衰减关系；最后，基于统计所得衰减关系比较分析了基于三种场地分类方法的地震动场地效应的特征和差异。

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Reproducing Acceleration Power Spectral Density from an Aircraft Fuselage Panel Excited by Turbulent Boundary Layer Using Piezoelectric Actuators

, 2017
Noise and vibration in an aircraft cabin during cruise conditions is predominantly caused by external flow excitations from the turbulent boundary layer. The turbulent boundary layer causes the fuselage panels on the aircraft to vibrate. These vibrations

Cognitive and Neuroimaging Divergence Between Juvenile and Adult FUS Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive motor neuron degeneration. Fused in sarcoma (FUS)‐associated juvenile ALS (jALS) represents a distinct and aggressive subgroup with rapid deterioration and poor prognosis.

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

Arthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.
