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.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Biophysical processes of morphogenesis in lizard lungs

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Epidemiology of Intensive Nutritional Interventions and Restraints in Hospitalizations for Anorexia Nervosa: Annual National Trends of the United States

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Despite the clinical relevance of enteral and parenteral tube feeding and restraint use in anorexia nervosa (AN), national‐level data on their use have remained limited, particularly for total parenteral nutrition (TPN) and percutaneous endoscopic gastrostomy (PEG).
