Similar capabilities to markedly control and manipulate X-ray radiation are highly desirable but practically impossible due to the massive size of the silicon single-crystal optics currently used. Here we show that micromechanical systems can be used as X-ray optics to create and preserve the ...

There is substantial and continuing progress and development in X-ray detector technology (for high spectral and time resolution), as well as high-throughput but modest angular resolution focusing optics, but X-ray astronomy is significantly falling behind other wavebands in its potential for ultra-...
ClassNumber TN911 l 引言 海面波浪、低空大气对流层和近海海岛、船只 等复杂海洋环境,往往被认为是制约海洋传输信道 的主要参量,影响海上与岸基之间信号交互传输的 障碍。本文引入射线跟踪理论,恰恰借助于这些参 量探讨海洋传输信道,并通过各种算法的支撑,分 析海上与岸基之间信号交互传输的可行性,为合理 使用海上用...
10. Usage Notes Data was stored in the CXIDB25 data format which uses the HDF5 format. HDF5 files are readable in many computing environments including python using the h5py module and MATLAB using e.g., the h5read function. Convenient functions for accessing the CXIDB data file exist in...
Phosphors emitting visible and near-infrared persistent luminescence have been explored extensively owing to their unusual properties and commercial interest in their applications such as glow-in-the-dark paints, optical information storage, and in vivo
