Early‐stage profiles of adolescent mental health difficulties and well‐being: A systematic review of cluster analyses in large school and community samples

open access: yesJournal of Research on Adolescence, Volume 35, Issue 4, December 2025.
Abstract Traditional diagnostic and services pathways often overlook the nuanced ways that mental health problems and strengths appear in community settings. Some researchers have therefore used person‐centered statistics—or clustering analyses—to identify profiles of socioemotional and behavioral difficulties and well‐being traits in preclinical ...

Real models for the framed little n$n$‐disks operads

open access: yesJournal of Topology, Volume 18, Issue 4, December 2025.
Abstract We study the action of the orthogonal group on the little n$n$‐disks operads. As an application we provide small models (over the reals) for the framed little n$n$‐disks operads. It follows in particular that the framed little n$n$‐disks operads are formal (over the reals) for n$n$ even and coformal for all n$n$.

Development of a Novel Machine Learning Model for Automatic Assessment of Quality of Transvaginal Ultrasound Images From Multi‐Annotator Labels

open access: yesAustralasian Journal of Ultrasound in Medicine, Volume 28, Issue 4, November 2025.
ABSTRACT Objectives Accurate diagnosis of pathology from ultrasound images is reliant upon images of a suitable diagnostic quality being acquired. This study aimed to create a novel machine learning model to automatically assess transvaginal ultrasound (TVUS) image quality for gynaecological ultrasound.

Commuting Pairs in Quasigroups

open access: yesJournal of Combinatorial Designs, Volume 33, Issue 11, Page 418-427, November 2025.
ABSTRACT A quasigroup is a pair ( Q , ∗ ), where Q is a nonempty set and ∗ is a binary operation on Q such that for every ( a , b ) ∈ Q 2, there exists a unique ( x , y ) ∈ Q 2 such that a ∗ x = b = y ∗ a. Let ( Q , ∗ ) be a quasigroup. A pair ( x , y ) ∈ Q 2 is a commuting pair of ( Q , ∗ ) if x ∗ y = y ∗ x.
