Responsivity and Stability of Nonlinear Exceptional Point Lasers with Saturable Gain and Loss

Autor: Darcie, Todd, Aitchison, J. Stewart

The responsivity of perturbation sensing can be effectively enhanced by using higher-order exceptional points (HOEPs) due to their nonlinear response to frequency perturbations. However, experimental realization can be difficult due to the stringent

6G Takes Shape

Autor: Andrews, Jeffrey G., Humphreys, Todd E., Ji, Tingfang

Publikováno v: IEEE BITS the Information Theory Magazine, Dec. 2024

The contours of 6G -- its key technical components and driving requirements -- are finally coming into focus. Through twenty questions and answers, this article defines the important aspects of 6G across four categories. First, we identify the key th

The estimation of uncertainties in cosmological parameters is an important challenge in Large-Scale-Structure (LSS) analyses. For standard analyses such as Baryon Acoustic Oscillations (BAO) and Full Shape, two approaches are usually considered. Firs

We present a novel Automatic Target Recognition (ATR) system using open-vocabulary object detection and classification models. A primary advantage of this approach is that target classes can be defined just before runtime by a non-technical end user,
