Automatic measurement of rice tiller angle from unmanned aerial vehicle images
Abstract Rice (Oryza sativa L.) tiller angle is an important trait that influences plant architecture, canopy light interception, and yield potential. In this study, we proposed a deep learning‐based pipeline for automated measurement of rice tiller angle and plant base width using unmanned aerial vehicle (UAV) imagery.

ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...

A 3D Model of Ryegrass Shoot Architecture, Sward Light Interception and Photosynthesis
Increasing the photosynthetic capacity of perennial ryegrass (Lolium perenne L.) is required to improve the productivity of pastoral farming in temperate regions. A three‐dimensional (3D) model was constructed of the shoot growth of ryegrass based on plant morphological traits such as tiller angle, leaf angle, leaf width, number of tillers per plant ...

An Active Beam‐Reconfigurable Retrodirective Array
The proposed beam‐reconfigurable retrodirective array not only enables retroreflection toward the signal source but also achieves flexible beam steering via a tunable reflection plate, offering a viable solution for real‐time multipoint communication and multitarget wireless power transfer.

Capsules in the forest: using unmanned aerial vehicle deployment, we tested pelleted capsules and engineered pods in greenhouse and field trials. Pods improved early field establishment compared with pelleted capsules, while predation remained a major limit to final survival.

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a
