WEST LAFAYETTE, Ind. — By using photons and electron spin qubits to control nuclear spins in a two-dimensional material, researchers at Purdue University have opened a new frontier in quantum science ...

A string is said to be a palindrome if it is the same if we start reading it from left to right or right to left. So given a string str, determine whether it is a palindrome or not. geeks is not a ...

This project validates whether a given string follows specific movement rules within a 4x4 character matrix. The string is valid if: Each character exists in the 2D array. Each character in the string ...

Orbital angular momentum of light is a fundamental optical degree of freedom characterized by unlimited number of available angular momentum states. Although this unique property has proved invaluable ...

Abstract: It is a challenging and attractive topic to extend the aperture dimension of linear arrays with convenient configuration for two-dimensional (2D) direction of arrival (DOA) estimation. In ...

Abstract: Compared to conventional 3D radar systems, 4D radar systems require higher angular resolution in both azimuth and elevation. Besides, sparse arrays offer several advantages, including ...
