A Novel Method for Generating a Fused Ventilation–Perfusion Map Using CT‐Derived Ventilation and FDG‐PET for Lung Functional Avoidance in Radiotherapy: A Feasibility Study

Precision Radiation Oncology, EarlyView.
This study retrospectively analyzed two types of respiratory phase CT and PET/CT images of 20 lung cancer patients. After DIR and functional grading, three lung function images were developed, and their correlations and differences were evaluated. Abstract Background Pulmonary ventilation–perfusion function plays a crucial role in both radiotherapy ...

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Quantifying aboveground herbaceous biomass in grassy ecosystems: a comparison of field and high‐resolution UAV‐LiDAR approaches

Remote Sensing in Ecology and Conservation, EarlyView.
The abundance of herbaceous vegetation in grassy ecosystems—which cover >25% of the world's land surface—is highly variable and impacts key ecological processes including carbon sequestration and support for grazing wildlife and livestock. Here, we present a method for using high‐resolution, UAV‐borne Light Detection and Ranging (LiDAR) to estimate ...

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils
