Physics-based estimation of effective toroidal momentum diffusivity in tokamak plasmas, with explicit treatment of ion–neutral interactions. Implements a Fourier–Bessel method applied to experimental ...

Last week, we began a history of attempts to map the Milky Way by determining the distances to stars. We started with second century BCE astronomer Hipparchus, who successfully calculated the moon’s ...

Abstract: In this paper, a synthesis and implementation method for generating Bessel beams based on time-reversal theory incorporating electromagnetic (EM) meta-lens is proposed. As is known, ...

Deep seismic sounding (DSS) profiles are one of the most powerful tools for detecting crustal structures, and they have been deployed worldwide. Generally, the analysis of DSS data mainly focuses on ...

This paper introduces a Terahertz (THz) ellipsometer thickness measurement method based on Bessel beams. The ellipsometry method is used to measure the thickness of film in the THz band. And the ...

I’m Ezra Klein, and this is “The Ezra Klein Show.” So one of the things I do for the show is I try to keep an eye on the best seller lists. And a few months ago, I began to notice something strange.
