Multiple ortho‐mosaicking software pipelines produce comparable imagery‐derived wheat phenotypes

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Unmanned aerial systems (UAS) equipped with multispectral and RGB sensors offer valuable data for monitoring crop health and assessing disease severity. However, the wide range of available photogrammetric software complicates software selection for high‐throughput plant phenotyping.

Intra‐MRI Head Motion Tracking and Correction: A Quantitative In Vivo Evaluation Framework

NMR in Biomedicine, Volume 39, Issue 9, September 2026.
This framework introduces, for the first time, an in vivo quantification of intra‐MRI head tracking accuracy and precision. By comparing a markerless optical system (MOS) and fat‐signal navigators (FatNav) against a rigid registration‐based reference standard, it successfully detects subtle, axis‐specific performance differences and strengths between ...

Effects of Body Size and Environmental Region on the Nutritional Value of Small Pelagic Species in the California Current

Fisheries Oceanography, Volume 35, Issue 5, Page 722-736, September 2026.
ABSTRACT We evaluated the effects of regional environment and body size on the nutritional traits of five small pelagic species differing in habitat use, feeding behavior, and importance as prey for top predators in the California Current Large Marine Ecosystem (CCLME).

Commissioning and clinical positioning assessment of a novel surface‐guided radiation therapy (SGRT) system at a C‐Arm linear accelerator

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Surface‐guided radiation therapy (SGRT) has been increasingly adopted in modern radiotherapy, enabling radiation‐dose‐free, marker‐free patient positioning with high accuracy. A novel SGRT system, LUNA 3D (LAP, Lüneburg, Germany), featuring a browser‐based interface, GPU‐accelerated surface reconstruction, high frame rates, large ...
