Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

High Precision Prediction Model of Wind Speed for Underground Mine Tunnel by Using ASTF Net
Energy Science &Engineering, EarlyView.This paper proposes an Adaptive Spectral‐Temporal Fusion Net (ASTF‐Net), which features a novel decomposition‐ensemble framework with adaptive feature fusion. This design deliberately balances spectral and temporal features and effectively boosts prediction accuracy in complex ventilation environments. ABSTRACT An Adaptive Spectral‐Temporal Fusion Net (

Energy Science &Engineering, EarlyView.The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems
Energy Science &Engineering, EarlyView.This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Keeping their powder dry: Purity, pollution, and handgun ownership among Jewish women in Israel
Feminist Anthropology, EarlyView.Abstract This article examines the gendered practices through which Jewish women in Israel experience and negotiate personal handgun ownership in everyday life. Drawing on interviews, participant observation in gun‐related spaces, and analysis of women‐only online forums, we explore the expanding participation of Jewish women in civilian gun ownership,
