In this paper, we first propose a new design strategy of 2D Z-complementary array quads (2D-ZCAQs) with feasible array sizes. A 2D-ZCAQ consists of four distinct unimodular arrays satisfying zero 2D ...

The first Java project task is to choose a framework. Here's how to select which one is right for your needs: Spring, Jakarta ...

Which matches the blocks that we placed in the game.

Circular array is a widely used omnidirectional scanning array. Nested array is a new variant of circular array. However, the traditional direction of arrival is not effective in estimating the ...

A two-dimensional polymer (2DP) single crystal (T-2DP) with submillimeter size was synthesized by single-crystal to single-crystal transformation based on photochemical [2 + 2]-cycloaddition. A ...

If you think that only large, spacious and bright house can fill you with joy and sense of family atmosphere, most likely you are mistaken. Sometimes a huge empty two-story mansion can quite ...

Gaze into the temporal distance and you might spot the end of the age of silicon looming somewhere out there, as a research team at Penn State University claims to have built the first working CMOS ...

Constructing nanoparticles into well-defined structures at mesoscale and larger to create novel functional materials remains a challenge. Inspired by atomic epitaxial growth, we propose an “epitaxial ...
