UAV‐Based Precision Seed Dropping for Automated Reforestation

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Wildfires and deforestation pose significant threats to forest ecosystems, motivating scalable methods for reforestation beyond labor‐intensive cultivation of native forest seedlings in nurseries. To enable large‐scale direct seeding of native species, this paper presents the design, analysis, and field evaluation of a UAV‐based seed‐dropping ...

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

AI‐Driven Circular Construction Waste Management for Advancing Sustainable Development

open access: yesSustainable Development, EarlyView.
ABSTRACT Construction and demolition waste (C&DW) represents up to 40% of global solid waste, posing a significant barrier to achieving circular economy (CE) objectives and the Sustainable Development Goals (SDGs), particularly SDG 11 and SDG 12. However, construction waste management (CWM) systems remain constrained by fragmented data environments ...

Macroscopic Convective Fluid Flows Arising From Binding of Ions and Small Molecules to Proteins

open access: yesSmall, EarlyView.
The interaction of ions or small molecules with proteins causes convective flows due to the displacement of water from the hydration shell. As shown, the replacement of the nickel ion removed from urease by EDTA pre‐treatment results in binding‐induced convective fluid flow.

Surface Locomotion of Cell‐Sized Microrobots Subject to Adhesive Heterogeneity

open access: yesSmall, EarlyView.
Chemically powered, cell‐sized microrobots exhibit translational, circular, or spiral motion through a balance among self‐phoretic propulsion, drag, gravity, and heterogeneous surface interactions. Experiments show that microrobot design and substrate conditions regulate both mobility and trajectory type.
