Review of Insulation Ageing and Lifecycle Management for Oil‐Immersed Power Equipment: From Conventional Testing Analysis to Artificial Intelligence Method

High Voltage, EarlyView.
ABSTRACT Oil‐immersed power equipment is a critical component for energy transmission and secure operation of modern power grids. The ageing of oil–paper insulation under combined electrical, thermal and mechanical stresses directly affects equipment lifetime and system reliability. This paper presents a comprehensive review of the ageing behaviour and

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.

Multi‐Model Fruit Quality Assessment With Coarse YOLOv11 Presence Filtering, Vision Transformers and the Segment Anything Model

Applied AI Letters, Volume 8, Issue 1, February 2027.
This paper presents a multi‐model deep learning pipeline for coarse fruit‐presence filtering, ripeness classification and pixel‐level spoilage segmentation. YOLOv11n is used only as an image‐level presence filter, four classifiers predict one of nine ripeness classes across three fruit types and the Segment Anything Model (SAM ViT‐H) generates fine ...

Full‐Space Terahertz Airy Beam Shaping via Composite Bilayer Metasurface With Switchable Amplitude–Phase Encoding Channels

Nanophotonics, Volume 15, Issue 21, 12 November 2026.
A composite bilayer metasurface integrates linear‐polarization amplitude–phase modulation with circular‐polarization Pancharatnam–Berry phase modulation, enabling multidimensional terahertz Airy beam manipulation within a single compact aperture. The highly integrated platform supports diverse Airy beam generation and offers new opportunities for ...
