Review and prospects of shear test of bolted rock joints

Deep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

On non-absolute functional Volterra integral equations and impulsive differential equations in ordered Banach spaces

Electronic Journal of Differential Equations, 2008
In this article we derive existence and comparison results for discontinuous non-absolute functional integral equations of Volterra type in an ordered Banach space which has a regular order cone.

‘Working Through’ Interpersonal Transgressions: The Role of Narration (and Re‐Narration) in the Self‐Forgiveness Processes of Wrongdoers

European Journal of Social Psychology, EarlyView.
ABSTRACT This research examines how wrongdoers may use narration to ‘work through’ a transgression committed, towards self‐forgiveness and reconciliation. In Study 1 (N = 30), reflexive thematic analysis was used to identify narrative types observable in wrongdoers’ storying of a recent interpersonal transgression, informing our conceptual framework ...

Cognitive and behavioral clinical outcome assessments in children with developmental and epileptic encephalopathies: Issues and instruments

Epilepsia, EarlyView.
Abstract Children with developmental and epileptic encephalopathies (DEEs) face cognitive and behavioral challenges that may have a greater impact than seizures on their quality of life (QoL). The need to assess these nonseizure outcomes for evaluating treatments is increasingly recognized.

Multiple Positive Periodic Solutions for Functional Differential Equations with Impulses and a Parameter

Abstract and Applied Analysis, 2014
We apply the Krasnoselskii fixed-point theorem to investigate the existence of multiple positive periodic solutions for a class of impulsive functional differential equations with a parameter; some verifiable sufficient results are established easily. In

Add‐on treatment with vinpocetine reduces seizure frequency and improves comorbidities in patients with loss‐of‐function γ‐aminobutyric acid type A receptor variants

Epilepsia, EarlyView.
Abstract Objective The semisynthetic compound vinpocetine has gained attention as a potential precision medicine for developmental and epileptic encephalopathies caused by loss‐of‐function (LoF) variants in γ‐aminobutyric acid type A (GABAA) receptor genes. As a positive allosteric modulator of GABAA receptors, case reports suggest that vinpocetine can

Controllability of impulsive functional differential systems with nonlocal conditions

Electronic Journal of Differential Equations, 2013
In this article, we study the controllability of impulsive functional differential equations with nonlocal conditions. We establish sufficient conditions for controllability, via the measure of noncompactness and Monch fixed point theorem.

On Mathematical Models Based on Delay Differential Equations in Epidemiology

Applied Sciences
This paper examines solutions to mathematical models based on functional-differential equations, which have applications in immunology. This new approach allows us to study discontinuous solutions that more accurately depict real-world phenomena. It also
