Random forest segmentation and spatial analysis of injected cardiac spheroids in optically cleared myocardium

Journal of Microscopy, EarlyView.
Abstract Accurate quantification of transplanted cardiac spheroids requires three‐dimensional (3D) localisation within intact myocardium, yet this remains technically challenging. Optical clearing and light‐sheet microscopy enable volumetric imaging of injection sites, but automated segmentation is difficult when transplanted spheroids and host tissue ...

Refined Composite Multiscale Fluctuation Dispersion Entropy and Supervised Manifold Mapping for Planetary Gearbox Fault Diagnosis

, 2023
A novel fault diagnosis scheme was developed to address the difficulty of feature extraction for planetary gearboxes using refined composite multiscale fluctuation dispersion entropy (RCMFDE) and supervised manifold mapping. The RCMFDE was first utilized

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

The 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.

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

Expert 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

Carbon 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

Human 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 ...
