The Pressure Gradient System [PDF]
The pressure gradient system is a sub-system of the compressible Euler system. It can be obtained either through a flux splitting or an asymptotic expansion. In both derivations, the velocity field is treated as a small remnant of the original velocity of the Euler system.

Advances of Surface Wind Speed Changes over China Under Global Warming
Previous studies indicate that surface wind speed (SWS) over China is declining continuously during past decades under global warming, and this has significant impact on wind energy resources.

ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
