More importantly, the thin-shell wormhole, if ever forms, possesses null energy density and null angular pressure on its throat which are preferable to their negative-valued counterparts.doi:10.1140/epjc/s10052-019-6964-4S. Danial Forghani
A thin-shelled reptile from the Late Triassic of North America and the origin of the turtle shell 来自 EBSCO 喜欢 0 阅读量: 30 作者:WG Joyce,SG Lucas,TM Scheyer,AB Heckert,AP Hunt 摘要: A new, thin-shelled fossil from the Upper Triassic (Revueltian: Norian) Chinle Group of New ...
We prove that for s < 0, s-concave measures on exhibit thin-shell concentration similar to the log-concave case. This leads to a Berry-Esseen type estimate for most of their one-dimensional marginal distributions. We also establish sharp reverse Hlder inequalities for s-concave measures....
The thin-shell instability has been named as one process, which can generate entangled structures in astrophysical plasma on collisional (fluid) scales. It is driven by a spatially varying imbalance between the ram pressure of the inflowing upstream plasma and the downstream's thermal pressure at ...
An X-ray reflective surface was applied via evaporation of a thin layer of gold (Figure 2). This was the approach used for the first conical mirrors. Another important aspect of the foil mirror concept is modularity [2]. A complete shell is divided into equal arc lengths, initially ...
In this article, spherically symmetric thin-shell wormholes supported by a generalized Chaplygin gas are constructed and their stability under perturbations preserving the symmetry is studied. Wormholes with charge and with a cosmological constant are analyzed and the results are compared with those obtain...
We consider the eigenvalue problem for a thin piezoelectric shell, of thickness 2∈, clamped along a portion of its lateralsurface under the geometrical as... N Sabu - 《Journal of Elasticity》 被引量: 20发表: 2002年 Nonlinear Hydrodynamics of Cosmological Sheets. II. Fragmentation and the Gr...
We investigate a new thin-shell wormhole constructed by surgically grafting two regular charged black holes arising from the action using nonlinear electrodynamics coupled to general relativity. The stress-energy components within the shell violate the null and weak energy conditions but obey the strong...
