Dissolution and Flow Channeling in Hydrate‐Bearing Sediments: Implications for Permeability
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract Estimates of in situ effective permeability of hydrate reservoirs are tens to hundreds of times less than most laboratory measurements on natural hydrate‐bearing sediments. The measured permeabilities are high because methane‐free water creates and expands flow channels in the sample during pressure core storage and laboratory testing.

Effects of Scattering of Radiation on Wormholes
Universe, 2018 Significant progress in the development of observational techniques gives us the hope to directly observe cosmological wormholes. We have collected basic effects produced by the scattering of radiation on wormholes, which can be used in observations ...

A Killing vector treatment of multiboundary wormholes
Journal of High Energy Physics, 2020 The two-sided BTZ black hole has been instrumental in elucidating several aspects of AdS/CFT. Similarly, multiboundary wormholes provide a useful and rich arena in which probing questions of quantum gravity can be posed and explored.

Density perturbations in the gas of wormholes
, 2010 The observed dark matter phenomenon is attributed to the presence of a gas of wormholes. We show that due to topological polarization effects the background density of baryons generates non-vanishing values for wormhole rest masses.

Engineering Reports, Volume 8, Issue 1, January 2026.Proposed cyber physical system security framework. ABSTRACT The increasing adoption of cyber‐physical systems (CPS) in Industry 4.0 has heightened vulnerability to cyber threats. This study proposes a machine learning–based intrusion detection framework, DBID‐Net, to effectively identify and prevent attacks in CPS environments. The framework integrates

Lessons on eternal traversable wormholes in AdS
Journal of High Energy Physics, 2019 We attempt to construct eternal traversable wormholes connecting two asymptotically AdS regions by introducing a static coupling between their dual CFTs.

Complementary in wormhole chromodynamics [PDF]
Physics Letters B, 1993 The electric charge of a wormhole mouth and the magnetic flux ``linked'' by the wormhole are non-commuting observables, and so cannot be simultaneously diagonalized. We use this observation to resolve some puzzles in wormhole electrodynamics and chromodynamics.

A non-gravitational wormhole [PDF]
Classical and Quantum Gravity, 2000 Using the effective metric formalism for photons in a nonlinear electromagnetic theory, we show that a certain field configuration in Born-Infeld electromagnetism in flat spacetime can be interpreted as an ultrastatic spherically symmetric wormhole. We also discuss some properties of the effective metric that are valid for any field configuration.
