Research Review: Mechanisms of change and between‐family differences in parenting interventions for children with ADHD – an individual participant data meta‐analysis

open access: yesJournal of Child Psychology and Psychiatry, Volume 66, Issue 9, Page 1304-1319, September 2025.
Background Understanding the mechanisms of change and between‐family differences in behavioural parenting interventions for children with attention‐deficit/hyperactivity disorder (ADHD) may help personalise interventions. Therefore, we examined whether improvements in parenting are associated with changes in child behaviour and functional outcomes, and

Signature of quaternionic Kaehler manifolds

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1983
Quaternionic Kähler manifolds have analogues of the Hard-Lefschetz theorem and the Hodge index theorem. The latter on the signature is simpler and clear cut. Let M be a compact connected quaternionic Kähler manifold of positive scalar curvature with dimension 4n. Theorem 1. \[ H^{2p}(M)=\sum_{2k\leq p}(L_{\Omega})^ k P^{2p-4k}(M),\quad p\leq n, \] and \

The Motion Picture: Leveraging Movement to Enhance AI Object Detection in Ecology

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
As AI methods become increasingly popular to automatically analyse ecology data, we investigate using movement information as a means to improve traditional object detection approaches (which are limited to static image information only) on over 35,000 annotated images from 1480 terrestrial, marine and freshwater locations, the most extensive ...

A transferable approach for quantifying benthic fish sizes and densities in annotated underwater images

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 1, Page 145-159, January 2025.
Abstract Benthic fishes are a common target of scientific monitoring but are difficult to quantify because of their close association to bottom habitats that are hard to access. Advances in image‐acquisition technologies, machine vision and deep learning have made capturing and quantifying fishes with cameras increasingly feasible.

Technical note: A biological anthropologist's guide for applying microbiome science to studies of human and non‐human primates

open access: yesAmerican Journal of Biological Anthropology, Volume 185, Issue 4, December 2024.
Abstract A central goal of biological anthropology is connecting environmental variation to differences in host physiology, biology, health, and evolution. The microbiome represents a valuable pathway for studying how variation in host environments impacts health outcomes.

Transformer‐based framework for accurate segmentation of high‐resolution images in structural health monitoring

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 24, Page 3670-3684, 15 December 2024.
Abstract High‐resolution image segmentation is essential in structural health monitoring (SHM), enabling accurate detection and quantification of structural components and damages. However, conventional convolutional neural network‐based segmentation methods face limitations in real‐world deployment, particularly when handling high‐resolution images ...

Characterization of Holomorphic Bisectional Curvature of GCR-Lightlike Submanifolds

open access: yesAdvances in Mathematical Physics, 2012
We obtain the expressions for sectional curvature, holomorphic sectional curvature, and holomorphic bisectional curvature of a GCR-lightlike submanifold of an indefinite Kaehler manifold.

Bi-Slant Submanifolds of Para Hermitian Manifolds

open access: yesMathematics, 2019
In this paper, we introduce the notion of bi-slant submanifolds of a para Hermitian manifold. They naturally englobe CR, semi-slant, and hemi-slant submanifolds. We study their first properties and present a whole gallery of examples.

Effects of pre‐treatment, historical age, and sample characteristics on the stable isotope analyses of killer whale (Orcinus orca) bone

open access: yesRapid Communications in Mass Spectrometry, Volume 38, Issue 19, 15 October 2024.
Rationale Stable isotope analysis of bone provides insight into animal foraging and allows for ecological reconstructions over time, however pre‐treatment is required to isolate collagen. Pre‐treatments typically consist of demineralization to remove inorganic components and/or lipid extraction to remove fats, but these protocols can differentially ...

Complex Osserman Kaehler Manifolds

open access: yes, 2010
Let H be a 4 dimensional almost Hermitian manifold which satisfies the Kaehler identity. Then H is complex Osserman if and only if H has constant holomorphic sectional curvature. We also classify in arbitrary dimensions all the complex Osserman Kaehler manifolds which do not have 3 eigenvalues.
