The Avoidance of the Little Sibling of the Big Rip Abrupt Event by a Quantum Approach

We address the quantisation of a model that induces the Little Sibling of the Big Rip (LSBR) abrupt event, where the dark energy content is described by means of a phantom-like fluid or a phantom scalar field. The quantisation is done in the framework of the Wheeler–DeWitt (WDW) equation and imposing the DeWitt boundary condition; i.e., the wave function vanishes close to the abrupt event. We a...

Stability of Accelerating Cosmology in Two Scalar-Tensor Theory: Little Rip versus de Sitter

We develop the general reconstruction scheme in two scalar model. The quintom-like theory which may describe (different) non-singular Little Rip or de Sitter cosmology is reconstructed. The number of scalar phantom dark energy models (with Little Rip cosmology or asymptotically de Sitter evolution) is presented. Stability issue of such dark energy cosmologies as well as the flow to fixed points...

Rip Currents

Scientific T To examine the spatial and temporal variability of rip currents using remote video imaging techniques. T To quantify changes in nearshore circulation and topography in response to varying incident wave conditions at different time scales including; P wave groupiness (time scales of 1-10 minutes), P tidal modulation (time scales of 12h and 24 h) and P wave height fluctuations associ...

The Paradox of Thrift: Rip

Perhaps the single most destructive tenet of Keynesian economics was its denigration of saving. Keynesianism has been used to justi~’ wasteful spending, massive deficits, and one after another scheme to redistribute wealth from those who would save it to those who would spend it. In keeping with this anti-saving doctrine, during the Christmas sellingseason of 1991, then President Bush made a bi...
