Charged Anisotropic Compact Stars in f(R, ϕ, X) Gravity: A Class I Embedding Approach With Reissner–NordstrÖm Exterior

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
This work examines the physical characteristics of charged, anisotropic compact spheres within the framework of f(R, ϕ, X) modified gravity. Starting from a static, spherically symmetric spacetime, we employ an Adler‐type ansatz for the temporal metric component gtt.

Effects of Evolving Precipitation on Chemical Transport Through Porous Media

open access: yesWater Resources Research, Volume 61, Issue 11, November 2025.
Abstract Flow through porous media together with precipitation and/or dissolution reactions involves a unique feedback behavior as these medium‐altering reactions affect the flow field and vice versa. Herein, the relationship between a gradually increasing degree of precipitation and the degree of anomalous transport (i.e., divergence from Fickian ...

MDS-Based Wormhole Detection Using Local Topology in Wireless Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2012
Wormhole attack is a severe threat to wireless sensor networks (WSNs), which has received considerable attentions in the literature. However, most of the previous approaches either require special hardware devices or depend on rigorous assumptions on the

A Hop-Count Analysis Scheme for Avoiding Wormhole Attacks in MANET

open access: yesSensors, 2009
MANET, due to the nature of wireless transmission, has more security issues compared to wired environments. A specific type of attack, the Wormhole attack does not require exploiting any nodes in the network and can interfere with the route establishment
