What will happen when I put more weight in the buckets?

During the 2026 Winter Olympics, athletes will leap off ramps, slide across ice and spin through the air. These performances ...

The second paper, "Fermion Chirality from Non-Bipartite Topology," applies this same lattice geometry to the quantum world. It proposes that the "handedness" (chirality) of subatomic particles is not ...

Abstract: One of the primary objectives of 2-D inverse scattering problems (ISPs) is to accurately characterize the nature of an unknown tomographic domain based on the collected scattered field data.

Abstract: In this study, a contrast source inversion (CSI) based physics-informed neural network method is proposed for solving inverse scattering problems. The proposed method constructs two sets of ...
