Skeptics of a recent investment spree involving OpenAI and others say deals raise questions about the robustness of the artificial intelligence boom. By Andrew Ross Sorkin Bernhard Warner Sarah ...

Abstract: In this article, we introduced an ultra-thin broadband single-layer metasurface (MS) comprising an S-shaped resonator (SSR) structure enclosed by a circular cover adhered on a dielectric ...

Impact Statement: An ultra-thin and broadband single-layer metasurface (MS) is proposed, which can achieve the circular polazrization (CP) conversion with an efficiency of approximately 22% for both ...

Circular breathing is a technique used by singers and wind instrumentalists to help create a continuous and uninterrupted tone. The technique, which requires inhaling through the nose, allows you to ...

Diagnosing the degree of vision impairment is a difficult task for even experienced optometrists, since it depends on the subjective response of the person tested. Normally, it is based on reading out ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

In the aberration analysis of a circular wavefront, Zernike circle polynomials are used to obtain its wave aberration coefficients. To obtain these coefficients from the wavefront slope data, we need ...
