浅壳与上地幔地震的水平加速度谱阻尼修正系数模型

open access: yesDizhen xuebao, 2019
对日本K-net和KiK-net台网中6 466条浅壳与上地幔地震动记录进行了统计分析,考虑四种场地类别分别建立了浅壳与上地幔地震的加速度谱阻尼修正系数模型,并利用随机效应模型将模型总残差分离为事件间残差、事件内残差(分为场地间残差和场地内残差),计算其相应的标准差,探究地震震源、路径、场地等因素对模型误差的影响。研究结果显示:所提出的模型能较好地拟合实际计算值,其随机误差整体随谱周期和阻尼比的增大而增大;震源效应导致的随机误差在谱周期小于2.0 s时小于其它效应;在大部分谱周期上 ...

Classical and Bayesian random-effects meta-analysis models with sample quality weights in gene expression studies

open access: yesBMC Bioinformatics, 2019
Background Random-effects (RE) models are commonly applied to account for heterogeneity in effect sizes in gene expression meta-analysis. The degree of heterogeneity may differ due to inconsistencies in sample quality.
