Inspired by the Japanese art of kirigami, an MIT team has designed a technique that could transform flat panels into medical devices, habitats, and other objects without the use of tools.

Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up ...

Abstract: This paper presents a method for constructing optimal frequency hopping patterns with ideal autocorrelation and cross-correlation properties based on algebraic Costas arrays. A ...
