The widespread PII signal transduction proteins are known Beta Carotene for integrating signals of nitrogen and energy supply and regulating cellular behavior by interacting with a multitude of target proteins.The PII protein of the cyanobacterium Synechococcus elongatus forms complexes with the controlling enzyme of arginine synthesis, N-acetyl-L-
GaAs-based, highly-efficient, kW-class, 1-cm laser bars with high peak power Popt and improved beam quality in quasi-continuous-wave mode are presented.The use of an extreme-triple-asymmetric (ETAS) epitaxial layer structure diminishes power saturation of high-power bars at oval endcap high driving current.The resulting ETAS bars with 4 mm cavity p
Alpine glaciers are vulnerable to climate changes, and their recession due to warming has already induced a large number of geohazards closely related to the glacial motion, such as debris flow.Strong coupling of the geology, geomorphology, climate, and glacial action controls the type, size, development, and frequency of debris flow along the Parl
