A Brief Review of Wormhole Cosmic Censorship
AxiomsSpacetime singularities, in the sense that curvature invariants are infinite at some point or region, are thought to be impossible to observe, and must be hidden within an event horizon.

Echoes from asymmetric wormholes and black bounce
European Physical Journal C: Particles and Fields, 2022 The time evolutions of the field perturbations in certain asymmetric wormhole and black bounce backgrounds are investigated. It is found that the echo signals arise only in some wormhole cases.

Wormhole effective mass and gravitational waves by binary systems containing wormhole
European Physical Journal C: Particles and FieldsWe considered the generation of gravitational waves by the binary system associated with a wormhole. In the Newtonian limit, the gravitational potential of a wormhole requires the effective mass of the wormhole taking into account radial tension effects.

Accretion Flow onto Ellis–Bronnikov Wormhole
Universe, 2021 Study of accretion onto wormholes is rather rare compared to that onto black holes. In this paper, we consider accretion flow of cosmological dark energy modeled by barotropic fluid onto the celebrated Ellis–Bronnikov wormhole (EBWH) built by Einstein ...

Establishing Shape Correspondences: A Survey
Computer Graphics Forum, EarlyView.Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Casimir wormholes in modified symmetric teleparallel gravity
European Physical Journal C: Particles and Fields, 2022 In recent years there has been a growing interest in the field of Casimir wormhole. In classical general relativity (GR), it is known that the null energy condition (NEC) has to be violated to have a wormhole to be stable.

Evaporation induced traversability of the Einstein--Rosen wormhole
, 2005 Suppose, the Universe comes into existence (as classical spacetime) already with an empty spherically symmetric macroscopic wormhole present in it. Classically the wormhole would evolve into a part of the Schwarzschild space and thus would not allow any ...

Exactly soluble model for self-gravitating D-particles with the wormhole [PDF]
, 2003 We consider D-particles coupled to the CGHS dilaton gravity and obtain the exact wormhole geometry and trajectories of D-particles by introducing the exotic matter.

The FEBS Journal, EarlyView.Exercise‐related microRNAs cel‐miR‐249‐3p and cel‐miR‐77‐5p in C. elegans regulate lifespan, fitness, mitochondrial morphology and membrane potential. Although lacking direct mammalian orthologs, H2O2‐induced microRNAs mmu‐miR‐181a‐5p and mmu‐miR‐378a‐3p regulate myogenesis, autophagy, mitochondrial content and respiration in murine myoblasts ...

, 2014 In this paper we are searching whether the wormhole solutions exists in different dimensional non- commutative inspired spacetimes. It is well known that the noncommutativity of the space is an outcome of string theory and it replaced the usual point ...
