A cut finite element method for the Biot system of poroelasticity

arXiv:2512.17521v1 Announce Type: new
Abstract: We propose a novel cut finite element method for the numerical solution of the Biot system of poroelasticity. The Biot system couples elastic deformation of a porous solid with viscous fluid flow and commonly arises on domains with complex geometries …

The k-Center Problem of Uncertain Points on Graphs

arXiv:2504.14803v2 Announce Type: replace
Abstract: In this paper, we study the $k$-center problem of uncertain points on a graph. Given are an undirected graph $G = (V, E)$ and a set $\mathcal{P}$ of $n$ uncertain points where each uncertain point with a non-negative weight has $m$ possible locati…

Controlling exciton flow in moiré superlattices: New method leverages correlated electrons

Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling the transport of energy in electronic devices. These pairs of charge carriers also emerge in transition metal dichalcogenides, thin semiconducting materials comprised of a tran…

Science says we’ve been nurturing “gifted” kids all wrong

A major international review has upended long-held ideas about how top performers are made. By analyzing nearly 35,000 elite achievers across science, music, chess, and sports, researchers found that early stars rarely become adult superstars. Most world-class performers developed slowly and explore…
