This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

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 ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

A new theory suggests that dark matter, which makes up most of the universe's mass, might not be invisible, it might be in ...
