Drift‐Corrected Monocular VIO and Perception‐Aware Planning for Autonomous Drone Racing

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The Abu Dhabi Autonomous Racing League (A2RL) x Drone Champions League (DCL) competition requires teams to perform high‐speed autonomous drone racing using only a single camera and a low‐quality inertial measurement unit—a minimal sensor set that mirrors expert human drone racing pilots.

Inferring Brown Bear Hair Snare Interactions by Automatically Detecting Bipedalism on Camera Trap Images Using Pose Estimation and a Multilayer Perceptron

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study proposes an automated method to infer brown bear hair snare interactions by detecting bipedal behavior in camera‐trap images using a pose estimation model and a multilayer perceptron (MLP). A YOLO‐based model, fine‐tuned from humans and dogs to a custom dataset, achieved high performance (≈93% keypoint precision and ≈96% classification ...

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Assessments as Sites for Teacher Sensemaking About Epistemic Learning Goals in Science

open access: yesScience Education, EarlyView.
ABSTRACT Recent science education reforms aim to broaden allowable ways of knowing and learning in science classes. Doing so requires that we attend to and work to shift messages about useful ways to know and learn (i.e., epistemological messages) embedded in course designs and enactments.

Is It Political? Science Teachers' Perspectives on GSD‐Inclusive Science Teaching

open access: yesScience Education, EarlyView.
ABSTRACT Teaching is often framed as neutral and apolitical, yet scholarship has long documented its entanglement with power, identity, and ideology. Despite growing attention to the sociopolitical dimensions of science education, less is known about what science teachers themselves understand as political and how those understandings shape where they ...
