A Vacuum‐Suction and Rotate End Effector for Robotic Apple Fruitlet Thinning: Comparative Development, Integrated Field Evaluation, and Preliminary Harvesting

open access: yesAdvanced Intelligent Systems, EarlyView.
Robotic apple thinning is constrained by a single field season confined to a few weeks each year. An efficient design process screens four detachment concepts off‐season using an artificial fruitlet structure, with field trials identifying vacuum suction and rotation as the most effective approach.

Farm labor scarcity and its uneven impacts on crop producers in the United States

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

Heterosis in crosses between remnant populations of the rare prairie forb Silene regia: Implications for restoration genetics

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Calls to adopt seed‐sourcing strategies in biological restoration that preserve local adaptation while maximizing genetic variation (e.g., regional admixture provenancing) are increasingly common. Heterosis, the increased fitness of progeny from crosses between populations relative to progeny from crosses within populations, could ...

From trust to translation: A trust‐based, evidence‐informed, and adaptive model for scalable technical assistance

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Technical Assistance (TA) is an essential strategy for supporting organizational growth and aiding implementation of evidence‐based interventions in mission‐driven sectors, including education. While TA is crucial for addressing challenges and improving performance, the field has limited consensus on key features and best practices ...

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

open access: yesAngewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...
