Moments in Time

It has been suggested that perception and action can be understood as evolving in temporal epochs or sequential processing units. Successive events are fused into units forming a unitary experience or "psychological present." Studies have identified several temporal integration levels on different time scales which are fundamental for our understanding of behavior and subjective experience. In ...

Harmonic continuous time branching moments

We show that the mean inverse populations of nondecreasing, square integrable, continuous-time branching processes decrease to zero like the inverse of their mean population if and only if the initial population k is greater than a first threshold m1 ≥ 1. If, furthermore, k is greater than a second threshold m2 ≥ m1, the normalized mean inverse population is at most 1/(k −m2). We express m1 and...

Moments in the Time andPolynomial - Based Transform

| Expressions for the rst-and second order moments of the energy distribution function of a signal in the original and the polynomial-based transform domain are derived. It is shown that these moments can be calculated without actually performing the transformation. It is argued that these results can be used to obtain compact signal-dependent transforms.

Time Invariance Violating Nuclear Electric Octupole Moments

The existence of a nuclear electric octupole moment (EOM) requires both parity and time invariance violation. The EOMs of odd Z nuclei that are induced by a particular Tand P-odd interaction are calculated. We compare such octupole moments with the collective EOMs that can occur in nuclei having a static octupole deformation. A nuclear EOM can induce a parity and time invariance violating atomi...
