Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

open access: yesDeep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Multivariate Trajectories of Eating Disorder Symptoms and Weight Status in 10‐ to 17‐Year‐Old Children and Adolescents

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Eating disorders (EDs) often emerge in adolescence, but developmental trajectories across different core features remain largely unclear. Method The prospective, community‐based study included N = 898 participants aged 9.5–17.5 years (47.6% female, age 11.8 ± 1.4 years) with annual follow‐up over 2–6 (3.4 ± 1.2) years.

Spectral entropy variability of intraoperative electrocorticography predicts outcome after epilepsy surgery in people with focal cortical dysplasia

open access: yesEpilepsia, EarlyView.
Abstract Objective Epilepsy surgery in people with focal cortical dysplasia (FCD) requires accurate removal of all epileptogenic tissue, and outcome is difficult to predict. We explored whether spectral entropy, a fast computable electroencephalographic (EEG) feature, could estimate epileptic activity in intraoperative electrocorticography (ioECoG) and

Sustainable Optimization of Emissions and Performance in Hydrogen Port Injection Diesel Engines Through Port Timing and Injection Duration Modulation

open access: yesEnergy Science &Engineering, EarlyView.
Optimizing hydrogen port injection in diesel engines significantly improves efficiency and reduces emissions, demonstrating a sustainable dual‐fuel strategy for cleaner transportation solutions and lower environmental impact. ABSTRACT This study evaluates a single‐cylinder hydrogen port injection (HPFI) Diesel engine by systematically varying the ...
