Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

Abstract: In this paper, we outline the domain of adequacy for the well-known approximation of physical optics (PO) for binary metasurfaces (MSs). First, we show that beyond the approximation of ...

Is it possible to 3d print a diffraction pattern? Martin Lewis issues warning over using debit cards Russell Crowe details health woes as he reveals the secret behind his 26kg transformation Mona has ...

It began as a strange discovery buried in chaos theory — a mathematical pattern that seemed to predict real events before they happened. From climate shifts to stock market crashes, scientists now ...

The Financial Industry Regulatory Authority (FINRA)’s Board of Governors has approved a major overhaul of its pattern day trading (PDT) rules, marking a critical shift in how active retail trading ...

This week, the trial starts in a consequential FTC lawsuit against Amazon. The suit alleges that Amazon for years "tricked" people into buying Prime memberships that were purposefully hard to cancel.

This paper presents the most comprehensive and up-to-date panel dataset on global trade invoicing currency and examines recent pattern shifts with a focus on geopolitical alignment. Using data for 132 ...

Bloom patterns could be useful, as engineers build folding structures to send to outer space. They’re also very pretty. Researchers have now found a new class of origami that they call bloom patterns, ...

Ptychography is an area-by-area scanning method that uses constant, coherent illumination to scan a region of a sample in several adjacent and overlapping locations. The dispersed radiation is ...

For centuries prime numbers have captured the imaginations of mathematicians, who continue to search for new patterns that help them identify primes and the way they are distributed among other ...

Abstract: X-ray ptychography is a lensless imaging technology with promising applications that can achieve nanometer resolution. However, the noise in the diffraction patterns degrades the performance ...
