Since Java 21, wrapper classes have played an increasingly sophisticated role in Java’s type system. Here’s everything you ...

An effective compensation method for the mutual coupling effect in uniform circular arrays (UCAs) employed for two-dimensional (2D) direction-of-arrival (DOA) estimations is introduced. A new 2D DOA ...

In this paper, we propose a novel two-dimensional direction of arrival estimation technique for sparse arrays. To this end, we estimate the 2D difference coarray corresponding to the radar’s sparse ...

Among the key goals of structural DNA nanotechnology are to build highly ordered structures self-assembled from individual DNA motifs in 1D, 2D, and finally 3D. All three of these goals have been ...
