Science Education, EarlyView.ABSTRACT Preservice elementary science teachers' beliefs and practices influence the kinds of adaptations they make to curriculum materials and the extent to which they are able to enact justice‐oriented science lessons. Through this qualitative study, we explored the beliefs and practices of five focal preservice teachers through an analysis of their ...

LOFF: LiDAR and Optical Flow Fusion Odometry
DronesSimultaneous 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 ...

Science Education, EarlyView.ABSTRACT This study centers the idea that it is not just what science teacher educators (STEs) teach, but how they teach it, that matters. To prepare future teachers who can enact more equitable and transformative reform‐oriented science instruction with multilingual learners, research must explore what STEs are doing, and how, to develop preservice ...

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

PEBO-SLAM: Observer Design for Visual Inertial SLAM With Convergence Guarantees
IEEE Transactions on Automatic ControlThis paper introduces a new linear parameterization to the problem of visual inertial simultaneous localization and mapping (VI-SLAM) -- without any approximation -- for the case only using information from a single monocular camera and an inertial measurement unit.

Single‐Particle Characterization Reveals Heterogeneous Extracellular Vesicle Fusion with Liposomes
Small Methods, EarlyView.This study used five orthogonal single‐particle techniques to compare how common mechanical methods fuse extracellular vesicles with liposomes. By quantifying fused‐particle yield, purity, and vesicle integrity, we found that freeze‐thaw and sonication generated the highest fusion but that all methods introduced membrane perturbation or damage.
