Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Bringing behaviour into focus: archaic landscapes and lithic technology

, 2004
This paper focuses on moving beyond characterization of the Lower and Middle Palaeolithic in terms of thetechnology and typology of lithic artefacts, to address the behaviour and cognitive capabilities of theArchaic hominid communities of which the ...

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Explainable hybrid stacking ensemble method for hard rock pillar stability prediction and engineering applications

Deep Underground Science and Engineering, EarlyView.
This research proposes an interpretable hybrid stacking ensemble framework, optimized by the Sparrow Search Algorithm, to enhance hard rock pillar stability prediction. By integrating six machine learning models—k‐nearest neighbors, support vector machines, random forests, Gradient Boosting Decision Tree, eXtreme Gradient Boosting, and Light Gradient ...

Efficacy of the Intervention Against the Stigmatization of Men With Eating Disorders in Primary Healthcare (iSMEsH): Results From a Randomized Waitlist‐Controlled Study

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Eating disorders (EDs) in men are underdiagnosed and undertreated, partly due to stigma hindering help‐seeking. This randomized waitlist‐controlled study tested the efficacy of the iSMEsH online anti‐stigma intervention targeting German general practitioners (GPs) and medical students.

Developing Transdiagnostic Single‐Session Interventions for University Students Experiencing Disordered Eating: A Mixed‐Method Co‐Design Study

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Many university students encounter barriers to timely support for disordered eating. Brief, scalable digital single‐session interventions (SSIs) may provide an engaging and accessible transdiagnostic pathway for early intervention where there is increased distress before a diagnosis emerges.
