Strong-Motion Data Processing and Product Generation System for Earthquake Early Warning Network

open access: yesApplied System Innovation
For processing timeliness, standardizing formats, and reflecting the variety of massive strong motion observation data of the National Seismic Network Center, we developed a strong motion data processing system applicable to different types of strong ...

Effective linear damping and stiffness coefficients of nonlinear systems for design spectrum based analysis [PDF]

open access: yes, 2010
A stochastic approach for obtaining reliable estimates of the peak response of nonlinear systems to excitations specified via a design seismic spectrum is proposed. This is achieved in an efficient manner without resorting to numerical integration of the

Meningovascular Inflammation in Cerebral Amyloid Angiopathy‐Related Cortical Superficial Siderosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The role of inflammation in cortical superficial siderosis (cSS), a marker of cerebral amyloid angiopathy (CAA) linked to high hemorrhage risk, is unclear. We examined 15 patients with cSS using 3 T post‐contrast vessel wall MRI (VWI) and CSF analysis.

Performance of Single Degree of Freedom (SDOF) Systems Subjected to The Near-Fault Earthquakes

open access: yesمجلة النهرين للعلوم الهندسية
This paper aims to assess the structures' seismic response with a system of Single-degree-of-freedom exposed to near-fault earthquakes, taking into account the effect of pulse period, shear wave velocity (VS30), and fault mechanism. Strong ground motion

The Acceleration Response Spectrum for Simulated Strong Motions Considering the Earthquake Characteristics of the Korean Peninsula [PDF]

open access: yesJournal of the Korean earth science society, 2007
The response spectrum is one of the important basic materials for the aseismic design. Numerous strong ground motions based on the seismic source characteristics for the earthquakes occurring in the Korean Peninsula were simulated to obtain the response spectra by using the computer program, SMSIM, developed by Boore (2005).

Functional and Structural Evidence of Neurofluid Circuit Aberrations in Huntington Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Disrupted neurofluid regulation may contribute to neurodegeneration in Huntington disease (HD). Because neurofluid pathways influence waste clearance, inflammation, and the distribution of central nervous system (CNS)–delivered therapeutics, understanding their dysfunction is increasingly important as targeted treatments emerge.

甘肃积石山MS6.2地震强地震动特性分析

open access: yesDizhen xuebao
2023年12月18日甘肃积石山发生了MS6.2地震,本文基于中国数字强震动台网和地震预警网相关台站捕获到此次地震的强震动加速度记录,对地震动峰值空间分布特征、方向性效应、上下盘特性及反应谱特性进行了分析,结果表明:此次地震的强地震动空间分布主要受发震断层展布的控制;近断层附近,破裂方向效应明显;上下盘特性显著影响了强地震动等值线分布;相较于基岩场地,土层场地加速度反应谱在低频段显著放大。此外,此次地震震中的地震动强度已显著超越了现行抗震设计规范中罕遇、极罕遇地震水平。

Efficacy of Intermittent Theta‐Burst Stimulation for Prolonged Disorders of Consciousness: A Prospective, Randomized, Controlled Trial

open access: yesAnnals 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

Innate Immune Reprogramming Mediated by Endogenous Retroelement Dysregulation Drives Multiple Sclerosis Progression

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Epigenetic reprogramming in hematopoietic stem and progenitor cells (HSPCs) and downstream myeloid cells, mediated by H3.3 downregulation and endogenous retroelement (ERE) overexpression, contributes to the progression of multiple sclerosis (MS). ABSTRACT Background Skewed myelopoiesis in the bone marrow has been identified as a key driver of multiple ...

A Comparative Study on the Design Spectra Defined by Several Codes of Practice on RC Building Located in Baghdad City

open access: yesمجلة النهرين للعلوم الهندسية, 2017
This paper studies the effect of different design spectral response acceleration parameters as suggested by the uniform building code (UBC), unified facilities criteria (UFC), and Iraqi seismic code(1997) (ISC 97) on the seismic response of reinforced ...
