Asymptotic behavior of second-order impulsive differential equations

open access: yesElectronic Journal of Differential Equations, 2011
In this article, we study the asymptotic behavior of all solutions of 2-th order nonlinear delay differential equation with impulses. Our main tools are impulsive differential inequalities and the Riccati transformation.

Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

open access: yesDeep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Solving fractional integro-differential equations with delay and relaxation impulsive terms by fixed point techniques

open access: yesBoundary Value Problems
This paper presents a systematic approach to investigating the existence of solutions for fractional integro-differential equation systems incorporating delay and relaxation impulsive terms. By employing suitable definitions of fractional derivatives, we

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

open access: yesEuropean 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 ...

Decolorization of Ponceau Red 4R with TiO2/ZnO: Effect of calcination temperature and Fe addition

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract The photocatalytic degradation of azo dyes using semiconductor oxides has emerged as a promising strategy for wastewater remediation. In this study, pure, mixed, and Fe‐doped oxide catalysts based on Zinc Oxide and Titanium Dioxide were synthesized and evaluated for the degradation of Ponceau 4R under ultraviolet irradiation.

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

open access: yesEpilepsia, 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.

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

open access: yesEpilepsia, 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

Learning Rocking Dynamics From Sparse Shake‐Table Data With Interpretable Physics‐Informed Neural Networks

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We present a hybrid interpretable Physics‐Informed Neural Network Long‐Short Term Memory (Hybrid PINN LSTM) framework for predicting the seismic response of rocking blocks. Existing analytical models rely on uncertain idealizations, while purely data‐driven and machine‐learning approaches lack physical consistency and interpretability.

Energy‐Based Characterisation of Earthquake Damage in Masonry Infills Through Combined In‐Plane and Out‐of‐Plane Experimental Tests

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The seismic capacity of structural systems/members is usually defined in terms of deformation thresholds. Although this is effective in many circumstances, disregarding cumulative quantities such as hysteretic energy may be ineffective when low‐cycle fatigue is relevant (e.g., long‐duration ground motions, very soft soils, ground‐motion ...
