A Distributed Multirobot Architecture for Decoupled Inspection and Localized Treatment in Precision Agriculture

open access: yesAdvanced Intelligent Systems, EarlyView.
A distributed multirobot architecture enables asynchronous vineyard inspection and localized treatment through a cloud‐based mission control center. Real‐world validation demonstrates reliable coordination of heterogeneous robots, accurate disease detection, and effective conversion of georeferenced observations into targeted treatment actions ...

Multi‐Stage Social Value Orientation‐Based Lane‐Changing Driving for Autonomous Vehicles

open access: yesAdvanced Intelligent Systems, EarlyView.
A multi‐stage SVO framework is developed to dynamically infer the social preferences of surrounding vehicles from human driving data. By combining offline learning, online SVO estimation, temporal intention tracking, and interaction‐aware planning, the framework enables autonomous vehicles to adapt lane‐changing decisions and trajectories to evolving ...

An Active Knee–Ankle–Foot Orthosis With Torque‐Dense, Low‐Impedance Knee Actuation

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents the simulation, design, and clinical validation of a robotic active KAFO with torque‐sensitive actuation. By passively and continuously adapting the transmission ratio in response to the knee torque, the torque‐sensitive actuator overcomes the tradeoff between torque, weight, and impedance observed in conventional robot actuators,

Light‐Gated Control of Brownian Rotation by a Molecular Motor

open access: yesAngewandte Chemie, EarlyView.
A light‐driven molecular motor acts as a reversible steric gate for a nearby Brownian rotor. Photoisomerization switches the rotor between fast and hindered rotational regimes by modulating steric congestion around the rotational axis. The motor–rotor architecture enables a five‐order‐of‐magnitude difference in the rotational barrier, demonstrating ...

Defect‐engineered tungsten oxide nanowires as redox‐metabolic nanozymes for gut inflammation‐infection syndromes

open access: yesBMEMat, EarlyView.
Defect‐engineered WO3 nanowires serve as a multifunctional nanozyme platform to treat IBD complicated by Salmonella co‐infection. By integrating catalytic ROS/RNS scavenging and targeted metabolic interference of pathogens via molybdenum substitution, these nanowires effectively resolve intestinal oxidative stress, inhibit infection, and restore ...

From muscle fibres to muscle gears: how dynamic fascicle orientation and shape change impact skeletal muscle function

open access: yesBiological Reviews, EarlyView.
ABSTRACT Skeletal muscle architectural design strongly affects force‐generating capacity and excursion range, and its functional importance to animal and human movement is well founded. Traditionally, this ‘structure–function relation’ has been inferred from architecture measurements with muscles at rest (from anatomical dissections or medical imaging ...

Emergency braking is affected by the use of cruise control

open access: yes, 2017
Objective: We compared the differences in the braking response to vehicle collision between an active human emergency braking [control condition] and cruise control [CC] or adaptive cruise control [ACC].Methods: In 11male subjects, age 22 to 67 years, we

The Degradation of Access‐Based Business Models: Customer Misbehavior and Shared Mobility

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Access‐based services are considered one of the strategies to embed sustainability in business models. Yet, because the evolution of these business models has been overlooked, we do not know whether their promise to create triple value is sustained.
