Scientists discovered a nuclear island that flies in the face of traditional chemistry

Known as “islands of inversion,” these odd regions are found among a sea of normal nuclei. Now, a new island may have been ...

Exploiting Symmetry in High-Dimensional Dynamic Programming

We propose a new method for solving high-dimensional dynamic programming problems and recursive competitive equilibria with a large (but finite) number of heterogeneous agents using deep learning. We ...

Reflection Symmetry Detection by Embedding Symmetry in a Graph

Abstract: Reflection symmetry is ubiquitous in nature and plays an important role in object detection and recognition tasks. Most of the existing methods for symmetry detection extract and describe ...

Crossing-symmetric bethe-salpeter equations and the generalized ladder graphs

We show that iteration of the crossing-symmetric Bethe-Salpeter equations with s−u crossing symmetry and t exchange will generate a subset of the generalized ladder graphs of the relativistic eikonal ...
