Study on fracture parameter calibration and failure characteristics of rock with hole and crack

open access: yesDeep Underground Science and Engineering, EarlyView.
The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Decorating Carbon Nitride via the Integration of Phosphorylation with Carbon Self‐doping toward Enhanced Photocatalytic Hydrogen Evolution

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The electron transfer from the grafted ATMP to the adjacent heptazine ring can induce the proton transfer of the hydroxyls on ATMP to Pt co‐catalyst nanoparticles. This coupling of proton transfer and electron transport also promotes the separation and transport of charge carriers and therefore advances the performance of photocatalytic hydrogen ...

Genetic testing for familial epilepsies: Diagnostic yield and genetic findings

open access: yesEpilepsia, EarlyView.
Abstract Objective Genetic testing has become a routine part of clinical epilepsy care. Family history is an indication for genetic testing, but the diagnostic yield, predictors of a genetic diagnosis, and association with familial patterns are not well understood.

Integrating multivariate resting‐state fMRI features to localize epileptic networks in common childhood epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Accurate localization of epileptic activity remains challenging when interictal discharges are absent or sparse. Although resting‐state functional MRI (rs‐fMRI) is noninvasive, individual rs‐fMRI metrics provide inconsistent and incomplete localization.

Comparison of Characteristics and Exergoeconomic Between Hydrogen and Natural Gas-Fueled Compressed Air Energy Storage Systems

open access: yes发电技术
ObjectivesThe natural gas-fueled compressed air energy storage (CAES) system presents environmental pollution challenges, and replacing natural gas with hydrogen as fuel cannot cause greenhouse gas emissions.

Epilepsy syndromes classification

open access: yesEpilepsia Open, EarlyView.
Abstract Epilepsy syndromes are distinct electroclinical entities which have been recently defined by the International League Against Epilepsy Nosology and Definitions Task Force. Each syndrome is associated with “a characteristic cluster of clinical and EEG features, often supported by specific etiologic findings”.
