Sedentary ageing remodels the structure–function relationships that underlie calcium signalling at super‐resolution scales in the heart

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Illustration of calcium spark function and ryanodine receptor (RyR) structure within a sedentary model of ageing. Upon sympathetic stimulation from 1 µM isoprenaline a linear response to calcium spark morphology occurred, accompanied by a biphasic progression of RyR remodelling across age.

Analysis of electroencephalograms in Alzheimer's disease patients with multiscale entropy [PDF]

open access: yes, 2006
The aim of this study was to analyse the electroencephalogram ( EEG) background activity of Alzheimer's disease ( AD) patients using multiscale entropy (MSE). MSE is a recently developed method that quantifies the regularity of a signal on different time

Dynamic Surface‐Enhanced Raman Scattering Platform With Multiscale Nanostructural Engineering and Programmable Surface Energy for Artificial Intelligence‐Assisted Discrimination of Helicobacter pylori

open access: yesAdvanced Oncology, Volume 1, Issue 1, December 2026.
This study develops a dynamic surface‐enhanced Raman scattering (D‐SERS) platform integrating multiscale nanoparticle geometry, quantum dot coupling, surface‐energy programming, and a multilayer perceptron model for AI‐assisted classification. It enables ultrahigh sensitivity, noninvasive detection, and specific Helicobacter pylori identification.

An Attention Aware Pooling Strategy for Efficient Multi‐Label Classification of Aerial Forest Imagery

open access: yesExpert Systems, Volume 43, Issue 12, December 2026.
ABSTRACT Accurate multi‐label classification of aerial forest imagery is a critical component of large‐scale forest monitoring, biodiversity assessment and climate‐related decision making. Unlike single‐label scenarios, natural forest scenes exhibit strong class co‐occurrence, severe class imbalance and spatially heterogeneous label relevance, which ...

MXenes for Boosting Potassium Ion Storage: Structure‐Property Relationships, Interface Science, Microscopic Mechanisms, and Application Perspectives

open access: yesCarbon Neutralization, Volume 5, Issue 6, November 2026.
MXene‐based potassium‐ion battery anodes are mapped by linking synthesis, surface chemistry, heterostructure design, and practical evaluation. Pristine MXenes and composites with carbon, oxides, sulfides, selenides, tellurides, and alloying phases are compared, while intercalation, pseudocapacitive, conversion/alloying, built‐in‐field, and trapping ...

SPARK‐ICA: Guided Frequency‐Resolved Dynamic Spatial ICA Reveals Fine‐Scale fMRI Network Dynamics

open access: yesHuman Brain Mapping, Volume 47, Issue 16, November 2026.
SPARK–ICA is a frequency‐resolved dynamic spatial ICA framework that decomposes time‐varying fMRI network maps into multiple spatial frequency bands. Applied to schizophrenia resting‐state data, it reveals complementary abnormalities in stable connectivity and rapid high‐frequency network interactions that are not captured by conventional dynamic ...
