Changes in neural activity thought to reflect brain aging may be partly influenced by age-dependent signals ‘leaking’ from the heart.

Abstract: The merit factor of a {−1, 1} binary sequence measures the collective smallness of its non-trivial aperiodic autocorrelations. Binary sequences with large merit factor are important in ...

First of all, in consideration of the aperiodic sampling and the transmission time, a novel type extended looped-functional is constructed. In the extended looped-functional, some integral state ...
