Intact ecosystems have the capacity for self-regulation, which keeps their complex structure of species—such as animals, ...

Like physics, math has its own set of “fundamental particles”—the prime numbers, which can’t be broken down into smaller ...

Abstract: A statistical approach to the dynamic characterization of system temporal behavior based on complex empirical orthogonal function (EOF) analysis is developed. This technique allows ...

Abstract: Widely linear (WL) models have been demonstrated to be superior to conventional strictly linear models for the estimation of noncircular complex and quaternion signals. Existing studies on ...
