Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

Advanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

A modified switched-boost DC-DC converter circuit with reduced current stress and output voltage ripple

, 2022
International audienceThis paper is aimed to propose an improved boost DC-DC converter, based on the idea of switched-capacitor and switched-boost converters. A modified version of the conventional switched-capacitor switched-boost converter is proposed,

Lost ground, lost value: Investigating the relationship between soil erosion and agricultural land value

American Journal of Agricultural Economics, EarlyView.
Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

Performance analysis of a new elevated gain switched inductor-based quasi-Z-source-T-type inverter for small-scale grid-tied WECS

Results in Engineering
Wind energy conversion systems (WECS) benefit greatly from minimizing the number of power conversion stages, as this simplification improves the overall system efficiency. Among the single-stage converter topologies, the quasi-Z-source inverter (qZSI) is

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks

Angewandte Chemie International Edition, EarlyView.
A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.
