Data‐Driven Vertiport Site Selection: A Two‐Stage Framework With Multi‐Source Urban Data and Scalable Optimization

ABSTRACT Urban Air Mobility (UAM) is increasingly recognized as a promising solution to alleviate urban congestion and improve transportation efficiency, playing a key role in developing sustainable urban infrastructure. A central challenge for UAM deployment is the siting of ver...

Adsorption of Meteoritic Sugars on Forsterite Surfaces: A First-Principles Study

Abstract Sugar-related organic molecules identified in carbonaceous meteorites provide key insight into the extraterrestrial inventory of prebiotic compounds. Here, density functional theory (DFT) calculations are used to investigate the adsorption of representative sugar acids a...
