Cardiovascular disease arises from lifelong accumulation of traditional and emerging risk factors that converge on shared pathophysiological pathways, leading to diverse clinical outcomes, and can be mitigated through integrated screening, prevention, and precision therapies. ABSTRACT Cardiovascular diseases (CVDs) remain the leading cause of morbidity

ABSTRACT Infrared (IR) stealth is crucial for improving the survivability of equipment. The growing demand for service in marine environments poses new challenges to the composition and structural design of existing IR stealth coatings. This study first investigates the effects of NaCl/water vapor corrosion on the IR stealth performance of GH3536 and a

Abstract Snow on sea ice modulates the Earth's radiation budget and sea ice mass balance, yet satellite retrievals of Arctic snow depth remain subject to substantial algorithmic uncertainty. We develop a multi‐model machine learning (ML) framework for retrieving spring snow depth over Arctic sea ice from Advanced Microwave Scanning Radiometer 2 (AMSR2).
