A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

open access: yesDeep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Food‐Related Attentional Biases in Restrained Eaters: A Meta‐Analysis

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Dietary restraint may contribute to the development and maintenance of eating disorders (EDs), with food‐related attentional biases (ABs) as a key underlying mechanism. We examined associations between dietary restraint and ABs and explored how several methodological factors (i.e., AB mechanism, mode of AB investigation, response ...

Strain and Band Modulation of WO3/SnSe Micro‐Nano Composites Achieving Superior Photocatalytic Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
WO3/SnSe micro‐nano composites demonstrate exceptional photocatalytic performance through synergistic strain and band modulation. Lattice strain modulation enhances methyl orange adsorption and visible light absorption, while Z‐scheme band alignment promotes efficient charge separation. The 2.5% WO3/SnSe composite achieves 99.71% degradation efficiency,

Localizing value of cutaneous ictal phenomena: A systematic review

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective Clinical observation of autonomic signs during seizures can aid in localizing the epileptogenic zone (EZ). We performed a systematic review and meta‐analysis to evaluate the localizing value of ictal cutaneous phenomena—piloerection, sweating, pallor, and flushing—in focal epilepsy and their relevance to presurgical evaluation ...
