Recognized and Realigned: A Veteran Teacher's Moves to Leverage Familiar Forms of Epistemic Agency While Using Next Generation Science Standard Inspired Materials

Science Education, EarlyView.
ABSTRACT For 3 days, Amy, a veteran middle school science teacher, struggled to engage students in using Next Generation Science Standards (NGSS)‐aligned curriculum designed to facilitate scientific argumentation. Amy consistently used productive framing bids or cues to redirect students from “doing school” toward sensemaking and “doing science ...

Analysis of visual SLAM for forest environments

The objective of this dissertation is to investigate visual navigation for robotics in the forest domain. Visual Simultaneous Localisation and Mapping (SLAM) is a core technology for deployment of robotic systems in many use cases, allowing a robot to ...

LOFF: LiDAR and Optical Flow Fusion Odometry

Drones
Simultaneous Location and Mapping (SLAM) is a common algorithm for position estimation in GNSS-denied environments. However, the high structural consistency and low lighting conditions in tunnel environments pose challenges for traditional visual SLAM ...

A Review on the Development and Key Technologies of Embodied Intelligent Industrial Robots in Smart Manufacturing

SmartBot, EarlyView.
Conventional industrial robots rely on predefined workflows and struggle to adapt to changing tasks and uncertain manufacturing environments. This review examines the development and key technologies of embodied intelligent industrial robots (EIIRs), highlighting a closed‐loop architecture that integrates human and industrial inputs, embodied ...

Towards Dense Visual SLAM [PDF]

, 2011
Visual Simultaneous Localisation and Mapping (SLAM) is concerned with simultaneously estimating the pose of a camera and a map of the environment from a sequence of images. Traditionally, sparse maps comprising isolated point features have been employed,

Mamba-DQN: Adaptively Tunes Visual SLAM Parameters Based on Historical Observation DQN

Applied Sciences
The parameter configuration of traditional visual SLAM algorithms usually relies on expert experience and extensive experiments, and the parameter configuration needs to be reset as the scene changes, which is a complex and tedious process.

Managing Robot Perception: How Families Present Their Faces to a Toy Robot

Symbolic Interaction, EarlyView.
Playing with a robot's face detection capabilities constitutes a praxeological approach to learning about new technology. We explore how family members discover suitable formations for a Cozmo robot to scan a single face, drawing on video recordings from Swedish homes. Taking an ethnomethodology and conversation‐analysis perspective, we demonstrate how

Gut microbiota dysbiosis in the inflammatory pathogenesis of diabetic retinopathy

VIEW, EarlyView.
This graphical abstract illustrates how gut dysbiosis drives diabetic retinopathy through the gut‐retina axis, a process unfolding in three interconnected stages. First, in the gut, a decrease in beneficial bacteria and an increase in pro‐inflammatory taxa compromise the intestinal barrier, causing a “leaky gut” that allows LPS to translocate into the ...

The Global Airways Unit: A Multidisciplinary Strategy for Early Diagnosis and Comorbidity Detection

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Chronic respiratory diseases impose a large global burden of morbidity, mortality, and cost. The concept of a global airway has become increasingly supported by epidemiologic, mechanistic, and clinical evidence. However, clinical care often remains fragmented between ear, nose, and throat (ENT), allergy, and pulmonology.
