Automated Lawn Maintenance: An Agronomic and Operational Review of Turf Health, Biodiversity, and Field Performance

Journal of Field Robotics, EarlyView.
ABSTRACT Grass mowing is one of the most resource‐consuming activities in green maintenance, whether in private areas such as home gardens or in public spaces like urban parks. In recent years, concerns related to climate change, human health, and sustainability have become increasingly prominent in green maintenance, leading manufacturers and industry

Poli-RRT*: optimal RRT-based planning for constrained and feedback linearisable vehicle dynamics [PDF]

, 2015
This paper proposes a Rapidly exploring Random Trees planning strategy (Poli-RRT*) that computes optimal trajectories in presence of vehicle constraints (e.g., differential and actuation constraints) without approximating the nonlinear dynamics, but ...

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

Small, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

Bidirectional variable probability RRT algorithm for robotic path planning

, 2012
The traditional goal-bias RRT is mentioned to improve the efficiency, but it has an inherent problem, when there are lesser vertexes, the search toward the goal is often invalid; however, when there are more vertexes, the search toward other regions is ...

SFK: Shape‐ and Function‐Grounded Keypoint Representation for Sequential Manipulation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Sequential manipulation is the process by which robots perform multiple interdependent steps to accomplish composite tasks, demanding tight integration of perception, planning and execution. Existing methods incorporate explicit features such as category, semantics, 6D pose or affordance to enhance consistency, yet single‐feature ...

Long-term outcomes after AKI in hospitalized patients with COVID-19

Nefrología (English Edition)
Introduction and objectives: Acute kidney injury (AKI) is frequent in hospitalized patients and contributes to adverse short- and long-term outcomes. We aimed to evaluate the association of AKI and long-term adverse renal events and mortality in a cohort
