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.

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.

Freshwater fish functional diversity shows diverse responses to human activities, but consistently declines in the tropics

open access: yesEcography, EarlyView.
Freshwater environments are intertwined with human activities and the consequence has been environmental degradation and biodiversity loss. Fish provide key ecological and economic benefits, and fish abundance and diversity can be affected by human activities resulting in functional diversity (FD) changes that might scale up to ecosystem impacts ...

Trajectories of quality of life, anxiety and depressive symptomatology, and health‐related work productivity after first seizure events

open access: yesEpilepsia Open, EarlyView.
Abstract Objective First seizure events are common and may exert an immediate and profound impact on people's lives. Less understood are their long‐term consequences. This prospective, longitudinal study aimed to measure and compare psychosocial and health‐related work productivity trajectories following first seizure events of various etiologies ...

Nonlinear Response‐History Analyses of Masonry and Mixed Structures With HybriDFEM

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The hybrid discrete‐finite element (HybriDFEM) method, previously developed to perform static and modal analysis in discrete and coupled discrete‐finite element models, is extended to nonlinear response‐history analyses. The equations of motion for the HybriDFEM model are solved through various numerical time‐integration schemes, both explicit
