Longitudinal chromic aberration as a function of refractive error

, 1993
The refractive error-dependence of longitudinal chromatic aberration was investigated, our hypothesis is being that myopia may be the outcome of inadequate cues to defocus.

Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

Responsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Time‐series digital camera photos combined with machine learning algorithms can realize accurate observation of flowering phenology

Remote Sensing in Ecology and Conservation, EarlyView.
Intelligent approaches are required to extract valuable phenological information from time‐series digital camera photos. In this research, we employed YOLO‐based object detection and semantic segmentation models to identify flowers and flower pixels, acquire flower count and flower cover data, and extract phenophases such as first, peak, and end ...

Two‐Photon Endomicroscopy for Image‐Guided Magnetic Micro‐Agents

Small, EarlyView.
Image‐guided manipulation of magnetic micro‐agents requires localized fluorescence feedback capable of resolving dynamic interactions in confined environments. This study introduces a two‐photon endomicroscopy platform for real‐time motion tracking, multicolor micro‐agent discrimination, and imaging through biological tissue.

CMesh: A Polymer‐Free Carbon Nanotube Scaffold for Robust TEM Specimen Preparation of Porous Graphene

Small, EarlyView.
CMesh, a polymer‐free carbon nanotube scaffold, reinforces pristine and pre‐existing porous graphene during TEM specimen preparation while preserving clean suspended imaging windows. The tunable mesh enables high‐yield transfer onto standard grids, atomic‐resolution imaging of nanopores and defects, and in situ observation under demanding microscopy ...
