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 ...

In January, a team led by Jim Schuck, professor of mechanical engineering at Columbia Engineering, developed a method for creating entangled photon pairs, a critical component of emerging quantum ...

Constructing out-of-equilibrium molecular assemblies that deviate from thermodynamic equilibrium is a central challenge in materials science. While numerous studies have reported the creation of such ...
