Stroke and motor outcomes are associated with regional and age‐specific changes in periodic and aperiodic cortical activity

open access: yesExperimental Physiology, EarlyView.
Abstract Historically, stroke and ageing have been associated with changes in narrow‐band periodic neuronal activity, but recent work has highlighted the importance of broad‐band aperiodic activity. Aperiodic activity is represented by the 1/f slope of power spectral density generated by cortical activity.

The cardiac pacemakers: A paradigm of robustness in evolutionary biology

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Functional networks in living systems are formed by many thousands of gene products. In association with those networks, several genes (four in this diagram) may be sufficient, each on its own, to ensure that the function occurs. Any one of these may be removed or blocked while leaving the others to continue functioning.

Aperiodic EEG and 7T MRSI evidence for maturation of E/I balance supporting the development of working memory through adolescence

open access: yesDevelopmental Cognitive Neuroscience
Adolescence has been hypothesized to be a critical period for the development of human association cortex and higher-order cognition. A defining feature of critical period development is a shift in the excitation: inhibition (E/I) balance of neural ...

A General Dynamic Programming Approach to the Optimal Water Storage Management for Irrigation

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 1987-1997, February 2026.
ABSTRACT This paper proposes a dynamic programming approach targeted to solve a natural resource problem of water storage management for irrigation in an environmentally and socially sustainable way. The problem we address in our formulation, focusing on the control of water storage in tanks, is based on assumptions that are less restrictive than those

The Relationship Between Task‐Related Aperiodic EEG Activity, Neural Inefficiency and Verbal Working Memory in Younger and Older Adults

open access: yesPsychophysiology, Volume 63, Issue 2, February 2026.
ABSTRACT Working memory (WM) decline in aging may be related to increases in “neural noise”, potentially reflected in the EEG aperiodic exponent. We reanalyzed previously published data to investigate age‐related differences in the aperiodic exponent during verbal WM and its relationship with neural inefficiency. EEG was recorded from 24 younger (18–35

Robust estimation of a Markov chain transition matrix from multiple sample paths

open access: yesStatistica Neerlandica, Volume 80, Issue 1, February 2026.
Markov chains are fundamental models for stochastic dynamics, with applications in a wide range of areas such as population dynamics, queueing systems, reinforcement learning, and Monte Carlo methods. Estimating the transition matrix and stationary distribution from observed sample paths is a core statistical challenge, particularly when multiple ...

Liquid Crystal Elastomers Under Confinement: A Review of Template‐Based Fabrication and Applications

open access: yesAdvanced Engineering Materials, Volume 28, Issue 1, January 2026.
Template‐assisted confinement offers powerful ways to control the alignment, structure, and function of liquid crystal elastomers. This review highlights several templating strategies and details how geometry and interfaces shape material responses.

Time‐Domain Near‐Field Scanning Microscopy of Terahertz Metasurfaces

open access: yesAdvanced Photonics Research, Volume 7, Issue 1, January 2026.
Time‐domain near‐field scanning terahertz microscopy provides direct access to subwavelength electromagnetic fields on metasurfaces. By combining controlled polarization excitation with nanoscale probing, this technique enables quantitative visualization of localized hotspots, surface‐wave propagation, and wavefront manipulation, offering a powerful ...
