A Tutorial on Bayesian Multi‐Study Factor Analysis With Applications in Nutrition and Genomics

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT High‐dimensional data are crucial in biomedical research. Integrating such data from multiple studies is a critical process that relies on the choice of advanced statistical models, enhancing statistical power, reproducibility, and scientific insight compared to analyzing each study separately.

3D Geometric Morphometric Analysis on Sexual Dimorphism in the Sella Turcica in Romanov Sheep Using CT Scan

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Three‐dimensional geometric morphometric analysis is a shape analysis method used to explain sexual dimorphism. In this context, a total of 13 anatomical landmarks were defined and analysed in the study, resulting in sex‐related shape variations. The study identified sex‐related morphological differences in the sella turcica structures of Romanov sheep

The differences in essential facial areas for impressions between humans and deep learning models: An eye‐tracking and explainable AI approach

British Journal of Psychology, Volume 117, Issue 2, Page 503-527, May 2026.
Abstract This study explored the facial impressions of attractiveness, dominance and sexual dimorphism using experimental and computational methods. In Study 1, we generated face images with manipulated morphological features using geometric morphometrics. In Study 2, we conducted eye tracking and impression evaluation experiments using these images to

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, Volume 248, Issue 5, Page 873-887, May 2026.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible

Boreas
The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is considered the common ancestor of all modern Ursini. U. minimus is thought to have been omnivorous, with a preference for invertebrates.

Three-dimensional magnetic resonance imaging-based statistical shape analysis and machine learning-based prediction of patellofemoral instability

Scientific Reports
This study performed three-dimensional (3D) magnetic resonance imaging (MRI)-based statistical shape analysis (SSA) by comparing patellofemoral instability (PFI) and normal femur models, and developed a machine learning (ML)-based prediction model ...

On the Whitney distortion extension problem for $C^m(\mathbb R^n)$ and $C^{\infty}(\mathbb R^n)$ and its applications to interpolation and alignment of data in $\mathbb R^n$

, 2017
Let $n,m\geq 1$, $U\subset\mathbb R^n$ open. In this paper we provide a sharp solution to the following Whitney distortion extension problems: (a) Let $\phi:U\to \mathbb R^n$ be a $C^m$ map.
