Challenges in Automatic Differentiation and Numerical Integration in Physics‐Informed Neural Networks Modelling

International Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.
ABSTRACT In this paper, we numerically examine the precision challenges that emerge in automatic differentiation and numerical integration in various tasks now tackled by physics‐informed neural networks (PINNs). Specifically, we illustrate how ill‐posed problems or inaccurately computed functions can cause serious precision issues in differentiation ...

Vision Transformer‐Enhanced Multi‐Descriptor Approach for Robust Age‐Invariant Face Recognition

Applied AI Letters, Volume 6, Issue 3, October 2025.
ABSTRACT This study presents a robust age‐invariant face recognition framework, addressing challenges posed by age‐related facial variations. Evaluated on the FGNet and Morph II datasets, the system integrates Viola‐Jones for face detection, SIFT and LBP for feature extraction, and Vision Transformers (ViTs) for global feature representation.

Boundary conditions and universal finite‐size scaling for the hierarchical |φ|4$|\varphi |^4$ model in dimensions 4 and higher

Communications on Pure and Applied Mathematics, Volume 78, Issue 10, Page 2001-2118, October 2025.
Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

Cognition–Eye–Brain Connection in Alzheimer's Disease Spectrum Revealed by Multimodal Imaging

Journal of Magnetic Resonance Imaging, Volume 62, Issue 4, Page 1119-1130, October 2025.
ABSTRACT Background The connection between cognition, eye, and brain remains inconclusive in Alzheimer's disease (AD) spectrum disorders. Purpose To explore the relationship between cognitive function, retinal biometrics, and brain alterations in the AD spectrum. Study Type Prospective.
