โœฆ Synopsis

Physicists interested in chronology-violating spacetimes have considered various strategies for avoiding the time travel paradoxes which can arise in those spacetimes. One such strategy is the adoption of a branching (non-Hausdorff) topology for spacetime. Branching spacetime models also arise in other physical contexts, such as the many-worlds interpretation of quantum mechanics. A known objection to the idea of branching spacetime stems from the fact that an observer in such a spacetime may have multiple futures or pasts. In this paper I describe a new non-Hausdorff spacetime model in which each observer has a unique history. This model differs topologically from previous non-Hausdorff spacetime models in that is not a T 1 -space.

This paper proposes a new type of time series model to identify the characteristics of non-linear dynamical structures. The model simultaneously accommodates three kinds of output signals, acceleration, velocity and displacement. This model is more sensitive to non-linearity than models utilising on

A new class of formulas for the time integration of the network model of diusion is described. The method uses time polynomials to model the potentials in the diusion ยฎeld. These formulas have been implemented and tested together with the classic CrankยฑNicolson (CN) scheme. Based on the chosen examp

A contemporary path model for the resolution of cultural and biological inheritance is extended to incorporate temporal variation in family resemblance. Specifically, the genetic and environmental effects, like all other parameters of the model, are allowed to vary over an individual's age according
