Separate Universe Simulations with IllustrisTNG: baryonic effects on power spectrum responses and higher-order statistics

open access: yes, 2019
We measure power spectrum response functions in the presence of baryonic physical processes using separate universe simulations with the IllustrisTNG galaxy formation model.

Strong-Motion-Duration-Dependent Power Spectral Density Functions Compatible with Design Response Spectra

open access: yesGeotechnics
The development of a suitable set of input ground motions is crucial for dynamic time history analyses. The US Nuclear Regulatory Commission (NRC) requires that these motions generate response spectra closely matching the plant’s design spectrum ...

Generation of simulated earthquake motions considering actual earthquake phase and multiple target response spectra

open access: yesJapan Architectural Review, 2020
Simulated earthquake motions whose response spectrums meet the multi‐target response spectrums are often used while designing earthquake resistant nuclear power plant facilities.

Seismic Characteristics of a Geotextile Tube-Reinforced Embankment and Shallow Foundations Laid on Liquefiable Soil

open access: yesApplied Sciences, 2023
The ground in Saemangeum has a high water level and is mostly composed of silty soil and sand, which makes it susceptible to liquefaction and seepage effects.

Relative Flux Calibration of Keck HIRES Echelle Spectra

open access: yes, 2003
We describe a new method to calibrate the relative flux levels in spectra from the HIRES echelle spectrograph on the Keck-I telescope. Standard data reduction techniques that transfer the instrument response between HIRES integrations leave errors in the

对人造地震动反应谱求解及拟合的几个相关问题探讨

open access: yesDizhen xuebao, 2018
为更高效合理地生成与设计反应谱相符的人造地震动信号,本文基于自主开发的地震动信号处理软件EQSignal对人造地震动生成过程中涉及的几个问题进行了探讨,并通过对单自由度简谐共振体系的响应分析,提出了具体的解决建议:① 反应谱求解时应该对高频段和低频段分别采用频域传递函数法和逐步积分法求解;② 反应谱周期控制点的分布模式也应分段处理,短周期段宜采用对数平均分布,长周期段宜采用线性平均分布,反应谱总周期控制点不宜少于120个;③ 人造地震动反应谱与设计反应谱拟合的过程中 ...

A stochastic approach for deriving effective linear properties of bilinear hysteretic systems subject to design spectrum compatible strong ground motions [PDF]

open access: yes, 2011
A novel statistical linearization based approach is proposed to derive effective linear properties (ELPs), namely damping ratio and natural frequency, for bilinear hysteretic oscillators subject to seismic excitations specified by an elastic response ...

Personalized Selumetinib Dosing in Pediatric Neurofibromatosis Type 1: Insights From a Pilot Therapeutic Drug Monitoring Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate selumetinib exposure using therapeutic drug monitoring (TDM) in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PN), assess interpatient pharmacokinetic variability, and explore the relationship between drug exposure, clinical response, and adverse effects.

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.
