Tiny melt traces shed light on the Colorado Plateau's explosive past

Deep beneath Earth's surface, some minerals hold clues to processes that happened millions of years ago. One such mineral is lawsonite, which forms under high pressure and relatively low temperatures. What makes it significant is its ability to store water within its crystal structure and carry it deep into Earth as tectonic plates move beneath one another.

Scientists develop novel model to forecast internal solitary waves from multiple sources in the Sulu Sea

A research team led by Professor Li Xiaofeng from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) has developed a model to forecast internal solitary waves originating from multiple sources in the Sulu Sea. The model combines physical equations and satellite observations to predict wave arrival times and crest positions across this complex marine environment.

Disjointness between Sets (3)

We prove Theorem 1 on 8/31/26 in this post. Given \( k, l, m \in [n] \) such that (1.1) and \( k \) mutually disjoint \( m \)-sets \( U_1, U_2, \ldots, U_k \), let \( \mathcal{H} \) be the family of \( l \)-sets each intersecting with every \( U_i \). Our goal […]
