Researchers from Harvard’s Department of Human Evolutionary Biology found that educated children perform better on psychological tests measuring executive function abilities, challenging the accuracy ...

Abstract: In this note, we define strong and weak common quadratic Lyapunov functions (CQLFs) for sets of linear time-invariant (LTI) systems. We show that the simultaneous existence of a weak CQLF of ...

Abstract: In this correspondence, we construct some new quadratic bent functions in polynomial forms by using the theory of quadratic forms over finite fields. The results improve some previous work.
