TL;DR: In this article, a sub-aperture scanning for the surface of spherical optical components and then obtaining surface defects information with image processing is presented. But the method is based on the principle of the microscopic scattering dark-field imaging, which can generate scattering light when an annular illumination beam irradiates on the surface.

TL;DR: In this article , the authors used Raman lidar (RL) water vapor mixing ratio (WVMR) and Doppler Lidar (DL) vertical velocity measurements at the Southern Great Plains (SGP) atmospheric observatory, which was established by the Atmospheric Radiation Measurement (ARM) user facility.

TL;DR: Wang et al. as discussed by the authors explored the changes of built-up areas at the beginning of the 21st century in Zhejiang Province, China, based on Geographic Information System (GIS) and Remote Sensing (RS).

TL;DR: In this article , the impacts of adding diluent gases (nitrogen, carbon dioxide, and helium) either to the fuel side or the oxidizer side on the sooting transition process in ethylene counterflow diffusion flames are investigated experimentally and numerically.

TL;DR: In this article , a tetra-metallic catalyst, ScTiTbAuAPO-5, with an extremely low surface gold atom concentration of 0.02%, has been designed and prepared via one-step hydrothermal crystallization.
