Researchers have developed a new analog photonic correlator that can be used to locate an object transmitting a radio signal. They demonstrated its ability to identify the location of a radio ...

For any symmetry in a Hamiltonian system, its spontaneous breaking in the ground state leads to a phase transition 11. The broken symmetry itself can assume many different forms. For example, the ...

The range of correlation coefficient of any bivariate discrete random vector with finite or countably infinite values is derived. We show analytically that the normal-transformed discrete bivariate ...

Joint mean-covariance regression modeling with unconstrained parametrization for continuous longitudinal data has provided statisticians and practitioners with a powerful analytical device. How to ...
