Advanced Science, EarlyView.Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

Advanced Science, EarlyView.A charge‐transfer‐engineered Ni catalyst derived from an atomically mixed layered precursor enables efficient ammonia‐to‐hydrogen conversion. Cr‐to‐Ni electron transfer creates electron‐rich Ni active sites that favor NH3 adsorption, modify the dehydrogenation energetics, and weaken N2 binding to facilitate product desorption. This electronically tuned

Routing In Leo-Based Satellite Networks
, 1999 Several strategies have been proposed for routing in a low earth orbit (LEO) satellite system. Some of them are based on the Internet Protocol (IP) and a few on asynchronous transfer mode (ATM) switching.
