Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...

Abstract: This paper presents a physics-informed stacking framework (PISF) for extrapolating the frequency-dependent radar cross section (RCS) of cluster targets. A stacked ensemble model is ...

Abstract: Physics-informed neural networks (PINNs) have recently been utilized to tackle wave equation-based forward and inverse problems. However, they encounter challenges in accurately predicting ...

ABSTRACT: With super high-rise buildings developing towards characteristics of low damping, light weight, and high flexibility, their wind-induced vibration and aeroelastic effects have become key ...

Accurate prediction of broadband ground motion parameters is crucial for earthquake disaster prevention and mitigation. However, physics-based ground motion simulations are limited by the lack of high ...

Researchers at CUNY ASRC and Florida International University have introduced complex frequency excitations as a new method to control light, sound, and other waves, surpassing conventional material ...

Tiny concentrations Qizhong Liang in Jun Ye's lab at JILA on the campus of the University Colorado Boulder. Liang and colleagues have developed a new technique for measuring trace concentrations of ...
