Abstract: In this letter, we propose a multisnapshot gridless direction of arrival (DOA) estimation method for uniform circular arrays based on shift-invariant beam pattern. Firstly, the arbitrary ...

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian ...

Global Navigation Satellite Systems (GNSS), including GPS, GLONASS, Galileo, and BeiDou, have become indispensable for a wide range of applications such as navigation, surveying, and timing ...

Sand-scorpions and many other arachnids perceive their environment by using their feet to sense ground waves. They are able to determine amplitudes the size of an atom and locate the acoustic stimuli ...

Abstract: In order to optimize the synthesis of Asymmetric Time-Modulated Circular Antenna Array (ATMCAA) and Symmetric Time-Modulated Circular Antenna Array (STMCAA), this work presents the Novel ...

From wound healing to organ development, cells rely on biomechanical signals to navigate their environment, coordinate behavior, and maintain function. Yet, understanding how cells interpret these ...
