Fracturing behaviors of flawed granite induced by dynamic loadings: A study based on DIP and PFC

open access: yesDeep Underground Science and Engineering, EarlyView.
This research examines granite's mechanical properties under split‐Hopkinson pressure bar testing, focusing on factors such as grain size and flaw dimensions. The study reveals that tension cracks are prevalent across grain sizes, with most intergrain cracks occurring between feldspar and quartz.

Toward staging differentiation for posttraumatic stress disorder treatment

open access: yesActa Psychiatrica Scandinavica, Volume 147, Issue 1, Page 65-80, January 2023., 2023
Abstract Objectives Several medical and psychiatric disorders have stage‐based treatment decision‐making methods. However, international treatment guidelines for posttraumatic stress disorder (PTSD) fail to give specific treatment recommendations based on chronicity or stage of the disorder.

Epiretinal membrane development after submacular perfluorocarbon liquid removal

open access: yesOman Journal of Ophthalmology, 2017
Optical coherence tomography of submacular perfluorocarbon liquid and its safe removal with a small gauge cannula have been presented in the report. This case was complicated by development of an epiretinal membrane, though visual acuity was preserved.

A review of multiscale numerical modeling of rock mechanics and rock engineering

open access: yesDeep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

An fMRI examination of the neural basis of suicide attempts: The role of mentalizing in the context of mood

open access: yesBipolar Disorders, Volume 24, Issue 8, Page 806-816, December 2022., 2022
Abstract Objectives Facial emotion recognition (FER) deficits in depressed mood disorder patients contribute to suicidality. Prior research shows that intrinsic brain activity patterns are altered by attempting suicide. Therefore, we investigated in depressed patients whether differences in FER contribute to their clinical symptoms of suicide.

Failure characteristics and the energy criterion of rock with a through‐going joint under true‐triaxial unloading conditions: Insights from the DEM model

open access: yesDeep Underground Science and Engineering, EarlyView.
The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...
