Characterization of the W-weighted Drazin inverse over the quaternion skew field with applications
, 2013 A characterization of the W-weighted Drazin inverse as well as some determinantal representations of the W-weighted Drazin inverse over the quaternion skew filed are derived.

The generalized Moore-Penrose inverse
, 1991 We define the generalized Moore-Penrose inverse and give necessary and sufficient conditions for its existence over an integral domain. We also prove its uniqueness and give a formula for it which leads us towards a “generalized Cramer's rule” to find ...

Sense of Coherence in the Perinatal Period: A Longitudinal Growth Mixture Modeling Analysis
Journal of Clinical Psychology, EarlyView.ABSTRACT Objectives Previous studies have established that higher Sense of Coherence (SoC) predicts lower pregnancy‐specific distress, fewer delivery complications, and increased birth satisfaction. However, less is known about how SoC typically changes over pregnancy, birth, and postnatally and the risk factors and protective factors contributing to ...

JCPP Advances, EarlyView.Abstract Background Emerging evidence indicates that real‐time assessments such as ecological momentary assessment (EMA) detect individuals experiencing suicidal ideation (SI) who go undetected by retrospective assessments. However, it remains unclear for whom and why such discrepancies occur.

JCPP Advances, EarlyView.Abstract Background People with neurodevelopmental and mental health conditions have been demonstrated to have elevated rates of sensory processing (SP) difficulties in research and practice but the temporal order of this relationship is unclear. Methods This study sought to investigate whether SP difficulties in infancy predicted mental health at 5 ...

Steroidopathies and hormonal imbalance in children and adolescents with autism spectrum disorder
JCPP Advances, EarlyView.Abstract Background Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition with a multifactorial etiology, many aspects of which remain unclear. Emerging evidence suggests a potential association between ASD and clinical manifestations resulting from hormonal imbalances, henceforth named “steroidopathies.” The present study aims to ...
