Estimating saturated hydraulic conductivity of soil samples from Kansas mesonet database
Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.Abstract In soil physics, saturated hydraulic conductivity, Ksat${{K}_{{\mathrm{sat}}}}$, is a key soil hydraulic parameter governing the movement of water and solutes, with broad implications for transport processes under variably saturated conditions. Its accurate estimation, however, is challenging and requires precise characterization of pore space.

Exploring a novel Einstein–Rosen BTZ wormhole
European Physical Journal C: Particles and FieldsWe introduce a novel Einstein–Rosen BTZ wormhole metric as a solution to the Einstein field equations with a negative cosmological constant and explore in detail its various phenomenological aspects. We show that the wormhole metric is characterized by a

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract We investigate how mineral dissolution reshapes flow pathways and solute transport in three‐dimensional discrete fracture networks using a computationally efficient graph‐based reactive transport model. The DFNs are inspired by field‐site observations of fractured carbonate and represent realistic connectivity and structural heterogeneity ...

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.

Bulk view of teleportation and traversable wormholes
Journal of High Energy Physics, 2018 We construct detailed AdS2 gravity solutions describing the teleportation through a traversable wormhole sending a state from one side of the wormhole to the other.

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

The Casimir Effect in Finite-Temperature and Gravitational Scenarios
PhysicsIn this paper, we review some recent findings related to the Casimir effect. Initially, the thermal corrections to the vacuum Casimir energy density are calculated, for a quantum scalar field, whose modes propagate in the (3+1)-dimensional Euclidean ...

A SURVEY ON DELAY AND NEIGHBOR NODE MONITORING BASED WORMHOLE ATTACK PREVENTION AND DETECTION
ICTACT Journal on Communication Technology, 2016 In Mobile Ad-hoc Networks (MANET), network layer attacks, for example wormhole attacks, disrupt the network routing operations and can be used for data theft. Wormhole attacks are of two types: hidden and exposed wormhole. There are various mechanisms in
