Modeling proppant transport and settling in a 3D propagating fracture

open access: yesDeep Underground Science and Engineering, EarlyView.
A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

open access: yesDeep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

Disordered Eating Symptom Profiles in Low‐Income, Racially Minoritized Adults

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Eating disorder (ED) research has traditionally assumed that symptoms cluster in the same way across populations. If this assumption is incorrect, models and assessment tools developed with advantaged samples may miss substantial symptom burden in marginalized populations.

Anatomy of a SPAN Particle: A Four‐Level Structural Framework for Lithium–Sulfur Batteries

open access: yesEcoEnergy, EarlyView.
Sulfurized polyacrylonitrile (SPAN) is a key cathode material for batteries. Borrowing the four‐level classification of protein structure, this perspective demonstrates SPAN's structural complexity into well‐defined levels, giving researchers clear research boundaries and targets at each level for improving battery performance.
