Engaging the public in plant science: Communication facilitators and barriers of scaling up a citizen science campaign

People and Nature, EarlyView.
Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Diverse Prairie Mixtures Stabilize Biomass Yields for Sustainable Aviation Fuel Production

PLANTS, PEOPLE, PLANET, EarlyView.
Meeting global demand for sustainable aviation fuel will require the additional production of vast quantities of plant biomass, which does not compete with food production or degrade sensitive ecosystems. Our multisite experiment shows that sowing diverse native prairie seed mixes—and managing them without intensive inputs—yields a more reliable ...

Deep Reinforcement Learning Based Autonomous Decision‐Making for Cooperative Uncrewed Aerial Vehicles: A Search and Rescue Real World Application

Journal of Field Robotics, EarlyView.
ABSTRACT This paper presents the first end‐to‐end framework that combines guidance, navigation, and centralized task allocation for multiple UAVs performing autonomous search‐and‐rescue (SAR) in GNSS‐denied indoor environments. A twin delayed deep deterministic policy gradient controller is trained with an artificial potential field (APF) reward that ...

Digital Twin‐Based Optimization of Service Availability in LEO Mega Constellations Considering Handover Delays in Open RAN

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...
