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

Critical currents for vortex defect motion in superconducting arrays
, 2005 We study numerically the motion of vortices in two-dimensional arrays of resistively shunted Josephson junctions. An extra vortex is created in the ground states by introducing novel boundary conditions and made mobile by applying external currents.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective People with epilepsy (PWE) may experience cognitive deficits but fail to undergo formal evaluation. This study compares cognitive status between PWE and healthy controls in the West African Republic of Guinea. Methods A cross‐sectional, case–control study was conducted in sequential recruitment phases (July 2024–July 2025) at Ignace ...

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。

Dynamic response and damage character of road embankment under strong earthquake
International Journal of Distributed Sensor Networks, 2018 Dynamic response of road embankment under strong earthquake was explored by site investigation, shaking table tests, and discrete element method simulations, which shows that the distribution of responded accelerations strongly depends on the amplitude ...

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.

Zero-Point cooling and low heating of trapped 111Cd+ ions
, 2004 We report on ground state laser cooling of single 111Cd+ ions confined in radio-frequency (Paul) traps. Heating rates of trapped ion motion are measured for two different trapping geometries and electrode materials, where no effort was made to shield the

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

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 ...
