Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

Integrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

evsBat: An automated toolkit for tracking and quantifying rapid movement of nocturnal animals using event cameras

Methods in Ecology and Evolution, EarlyView.
Abstract Capturing the high‐speed behaviour of nocturnal animals remains technically challenging because conventional video systems require intense illumination that disrupts natural activity. Event‐based vision sensors (EVS) overcome this constraint, yet their ecological uptake has been slow owing to a lack of software capable of analysing the sparse,

Short‐Term Surgical Outcomes: Modified Dorsal Inlay Graft Versus Tubularized Incised Plate Urethroplasty in Pediatric Hypospadias With Narrow Urethral Plates

Andrology, EarlyView.
ABSTRACT Background Reconstructing the urethra presents in hypospadias surgery is difficult. Occasionally, the urethral plate (UP) may be quite narrow, necessitating augmentation or replacement to achieve additional tubularization. Objective The objective of this research was to assess the application of modified dorsal inlay graft (mDIG) and ...

Flight Testing of Novel Compliant Spines for Passive Wing Morphing on Ornithopters [PDF]

, 2013
Unmanned Aerial Vehicles (UAVs) are proliferating in both the civil and military markets. Flapping wing UAVs, or ornithopters, have the potential to combine the agility and maneuverability of rotary wing aircraft with excellent performance in low ...

Democratising Multi‐Projector Displays

Computer Graphics Forum, EarlyView.
Spatially augmented reality (SAR) transforms large, surround, collaborative experiences out of VR/AR headsets to the real world by merging content from projectors with the physical environment. This detailed state‐of‐the‐art survey reports on the advancements in multi‐projector aggregation and hardware technologies used to achieve SAR and build ...

Design, Training, and Field Validation of a YOLOv8‐Based Automated Trap for Remote Detection of Codling Moth, Cydia pomonella

Entomologia Experimentalis et Applicata, EarlyView.
We developed and field‐validated a fully automated trap for Cydia pomonella monitoring, combining a camera with a YOLOv8 object‐detection model for remote insect identification. In controlled laboratory validation, the model showed strong performance (precision 0.77, recall 0.83), with moderate reductions under field conditions. Across six experiments,
