A study of signals and linear systems and their applications in modern engineering. Representation of continuous and discrete time signals and systems in the time and frequency domains. Stability, ...

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 ...

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

WASHINGTON — Researchers have developed a new analog photonic correlator that can be used to locate an object transmitting a radio signal. Because the new correlator is faster than other methods and ...
