In this paper, we study the charged and uncharged BTZ counterpart of black-bounce proposed by Simpson Visser recently. For case, find that temperature is not modified bounce parameter. We also wormhole side solution must always be supported exotic matter over throat. thermodynamics changed parameter controls a phase transition, affecting sign heat capacity therefore stability system. there are ...

Behavior of the Euclidean path integral at large orders of the perturbation series is studied. When the model allows tunneling, the path-integral functional in the zero instanton sector is known to be dominated by bounce-like configurations at large order of the perturbative series, which causes non-convergence of the series. We find that in addition to this bounce the perturbative functional h...

We study the explosion mechanism of collapse-driven supernovae by numerical simulations with a new nuclear EOS based on unstable nuclei. We report new results of simulations of general relativistic hydrodynamics together with the Boltzmann neutrino-transport in spherical symmetry. We adopt the new data set of relativistic EOS and the conventional set of EOS (Lattimer-Swesty EOS) to examine the ...

The first unambiguous measurements of a bounce-resonance effect in a non-neutral plasma are presented. Two striking signatures are observed when a magnetized electron column is heated by oscillating an end sheath. First, the heating rate increases by a factor of 104 as the oscillation frequency is increased by a factor of 10 near the thermal electron bounce frequency. Second, the heating is enh...

This paper looks into various ways of extending a Geometrically Based Single Bounce Channel Model into a Multiple Bounce one, the main motivation being to overcome some of the limitations of the former models. Three different strategies to implement the way rays are bounced are described and compared, a comparison between diffuse scattering and specular reflection being also investigated; as ex...

We investigate the condition for the bounce of circular disks which obliquely impacts on fluid surface. An experiment [ Clanet, C., Hersen, F. and Bocquet, L., Nature 427, 29 (2004) ] revealed that there exists a “magic angle” of 20◦ between a disk’s face and water surface in which condition the required speed for bounce is minimized. We perform three-dimensional simulation of the diskwater imp...

We consider vacuum tunneling of a new kind where the false vacua are not translationally invariant, but have topological defects that break some of their translational symmetries. In the particular case where the topological defects are cosmic strings, we show the existence of an O(2)×O(2) symmetric bounce configuration that allows a semi-classical estimate of the rate of cosmic string induced ...

The multitude of explanations for the January effect leaves the reader confused about its primary cause(s): is it tax-loss selling, window dressing, information, bid-ask bounce, or a combination of these causes? The confusion arises, in part, because evidence has generally been presented in support of a particular hypothesis though the same evidence may be consistent with another hypothesis. Fu...

Ground penetrating radar (GPR) is a widely used sensor for land mine detection. However, GPR signal return is very susceptible to ground bounce and reflection of clutter objects, which makes the detection a difficult problem to date. In this paper, we propose to utilize two-sided linear prediction (LP) to model the background interference and then employ the residue energy to generate the test ...
