Brillouin–Raman micro‐mapping of silicone‐hydrogel contact lenses: Revealing chemical and mechanical heterogeneities

Journal of Microscopy, EarlyView.
Abstract Joint Brillouin–Raman micro‐spectroscopy (BRMS) enables simultaneous, non‐destructive characterisation of the mechanical and chemical properties of soft materials at the micrometre scale, combining GHz‐range viscoelastic information from acoustic modes with the vibrational fingerprint of molecular species.

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

Restoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Gravel and sand barrier preservation at geological (Cenozoic) timescales: Insights from the southern Namibia continental shelf

Sedimentology, EarlyView.
ABSTRACT An apparent disconnect exists between the morphology and behaviour of modern coastal barriers and barrier‐associated sediments preserved in the geological record, reflecting modification and selective preservation over geological timescales.

Fault Diagnosis Method for DC Current Transformers Based on Deep Learning Hybrid Model

Vector: The Journal of Engineering, Volume 2027, Issue 1, January/December 2027.
Aiming at the problems of scarce fault samples, strong noise interference and complex feature coupling in the current DCCT fault diagnosis process, a DCCT fault diagnosis method based on a hybrid deep learning model is proposed. The performance of the proposed method is verified through experiments.

Using Small Unoccupied Aerial System (sUAS) Multispectral Imagery to Compare Hydrodynamics Around Different Aged Patches of Marsh Vegetation

Ecohydrology, Volume 19, Issue 7, November/December 2026.
ABSTRACT Wetland vegetation influences water and sediment transport by altering flow resistance. Vegetation presence, stem density, leaf and stem morphology, and flexibility, among other characteristics, control the degree to which vegetation impacts transport patterns.
