Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by ...

With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a ...

Abstract: One challenge in the design of frequency-selective surface (FSS) is that the designed results are difficult to meet the accuracy demand of various physical properties simultaneously, part of ...

Cold atoms could also potentially measure much lower vacuum pressures than ion gauges can. The current lowest pressure they’ve reliably measured is around 10 -9 Pa, and NIST scientists are working on ...

Abstract: Recently, domain alignment and metric-based few-shot learning (FSL) have been introduced into hyperspectral image classification (HSIC) to solve the issues of uneven data distribution and ...
