Investigations of the Windage Losses of a High-Speed Shrouded Gear via the Lattice Boltzmann Method
Applied SciencesTo suppress the adverse effect of the gear windage phenomenon in the high-speed aeronautic industry, a shroud as an effective alternative strategy is usually to enclose gears to reduce the windage behaviors of high-speed gears. To deeply understand these

21st‐Century Mangrove Expansion Along the Southeastern United States
Global Change Biology, Volume 32, Issue 1, January 2026.Global warming is driving poleward range shifts worldwide, including the northward expansion of tropical mangroves along the Atlantic coast of North America. In this region, warming winters are enabling mangroves to encroach into salt marsh–dominated temperate latitudes, potentially transforming wetland ecosystem function and services. To assess future
