Comparative Dynamics Enables Discovery of Embedded Bacterial Ferredoxin Domains in Large Redox Enzymes

Proteins: Structure, Function, and Bioinformatics, Volume 93, Issue 11, Page 1973-1987, November 2025.
ABSTRACT Bacterial ferredoxins are small iron–sulfur binding proteins that function as soluble electron shuttles between redox enzymes in the cell. Their simple 2×(β–α–β) fold, central metabolic function, and ubiquity across all kingdoms of life have led to the proposal that ferredoxins were likely among the earliest proteins.

Investigating the gaze‐driven reversed congruency effect in the spatial Stroop task: A distributional approach

British Journal of Psychology, Volume 116, Issue 4, Page 1107-1127, November 2025.
Abstract This study investigated how social (faces and eyes) and non‐social (arrows) stimuli modulate attentional orienting in a spatial Stroop task, using a distributional approach. Data from 11 studies (N = 705) were analysed through cumulative distribution functions (CDF), delta functions, and polynomial trend analyses. Three models were applied: (1)

The generalized Hausman test for detecting non‐normality in the latent variable distribution of the two‐parameter IRT model

British Journal of Mathematical and Statistical Psychology, Volume 78, Issue 3, Page 734-756, November 2025.
Abstract This paper introduces the generalized Hausman test as a novel method for detecting the non‐normality of the latent variable distribution of the unidimensional latent trait model for binary data. The test utilizes the pairwise maximum likelihood estimator for the parameters of the latent trait model, which assumes normality of the latent ...

Fractional Gaussian Noise: Spectral Density and Estimation Methods

Journal of Time Series Analysis, Volume 46, Issue 6, Page 1146-1174, November 2025.
The fractional Brownian motion (fBm) process, governed by a fractional parameter H∈(0,1)$$ H\in \left(0,1\right) $$, is a continuous‐time Gaussian process with its increment being the fractional Gaussian noise (fGn). This article first provides a computationally feasible expression for the spectral density of fGn.

Development of a Projection‐Based Advanced Deterministic Uncertainty Analysis in Low Dimensions

International Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.
ABSTRACT This paper provides an in‐depth exploration of reduced order modeling and uncertainty quantification relevant to engineering disciplines. The objective of this study is to develop an innovative uncertainty quantification algorithm incorporating a reduced order model suitable for complex system calculations, with the goal of maintaining an ...
