Dizhen xuebao本文将基于压缩感知理论的地震观测数据重建方法用于天然远震事件的P波到时处理之中，基于曲波（curvelet）变换，建立基于L1范数的正则化反演模型，并采用迭代收缩阈值算法（ISTA）求解该模型。针对在内蒙古布设的流动地震台阵记录到的远震波形数据，对其进行稀疏采样，采用稀疏反演重建方法对欠采样数据进行重建，并拾取重建数据的P波到时，之后开展远震P波层析成像进行验证。研究结果表明，远震天然地震观测数据在曲波变换中表现出稀疏性，可利用压缩感知方法实现远震P波数据的完备化处理 ...

Tracking of [14C]Polystyrene Nanoplastics in Pregnant Mice
Advanced Science, EarlyView.This study investigates [14C]polystyrene nanoplastic ([14C]PS) translocation in late‐stage pregnant mice after intranasal (0.5 mg of [14C]PS on GD12, GD14, and GD16, n = 6) and intravenous administration (1.5 mg of [14C]PS on GD16, n = 6). 14C‐radiolabel allows quantitative tracking of unmodified polystyrene nanoplastics.
