Site- and Motion-Dependent Parametric Uncertainty of Site-Response Analyses in Earthquake Simulations [PDF]

, 2010
We investigate the propagation of uncertainty in site-response analyses from the soil model parameters to the ground surface motion at three downhole array sites in the Los Angeles (LA) Basin.

近断层地震动加速度峰值比和脉冲特征的统计分析

Dizhen xuebao
为进一步了解近断层地震动的显著竖向特性和速度脉冲特性，基于NGA-West2强地面运动数据库选取1 706组强地震动记录，研究了竖向与水平向加速度峰值比aV/aH的总体分布特征，并探讨了aV/aH随矩震级MW、断层距Rjb、场地类别和断层类型变化的规律。在此基础上，通过Baker脉冲识别方法选取出140组近断层速度脉冲地震动，并提取出每条地震动记录的脉冲周期Tp和速度脉冲峰值PGVp，研究其脉冲参数随矩震级MW和断层距Rjb变化的统计规律及经验模型。结果表明：近断层加速度峰值比aV ...

Dynamics of Stripes in Doped Antiferromagnets [PDF]

, 1997
We study the dynamics of the striped phase, which has previously been suggested to be the ground state of a doped antiferromagnet. Starting from the t-J model, we derive the classical equation governing the motion of the charged wall by using a ...

Improving Foot-Mounted Inertial Navigation Through Real-Time Motion Classification

, 2018
We present a method to improve the accuracy of a foot-mounted, zero-velocity-aided inertial navigation system (INS) by varying estimator parameters based on a real-time classification of motion type.

Ground-Motion Intensity Measures for the Seismic Response of the Roof-Isolated Large-Span Structure

Buildings
Ground-motion intensity measures (IMs), which quantify and describe the characteristics of earthquake ground motion, are of utmost importance in the assessment of seismic risk and the design of resilient structures with large spans.

Financial Burden Associated With Hospitalisation Among Families of Childhood Brain Tumours in Australia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...
