Efficient and Accurate Spatio‐Temporal Population Monitoring of Mobile Animals Using Drones and Computer Vision

Remote Sensing in Ecology and Conservation, EarlyView.
Drones and computer vision offer an efficient way to estimate animal populations over localized areas, but surveys often require stitching many overlapping images together. If animals move during the survey, traditional orthomosaic‐based counting methods become unreliable, with some animals appearing in multiple locations while others appear not at all,

A Tracking‐By‐Detection Framework to Automatically Count Rare and Elusive Megafauna in Aerial Video Surveys

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring programs of vulnerable megafauna increasingly rely on aerial surveys from drones or planes fitted with cameras. However, automated methods are still lacking to accurately count individuals across entire surveys. Here, we leverage a tracking‐by‐detection framework to not only detect individuals but also link the resulting detections across ...

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

Remote 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.

Laponite Network Controls FGF‐2 Release and Drives Functional Nerve Regeneration via 3D‐Printed Nerve Wrap Interfaces

Small Methods, EarlyView.
We developed a 3D‐printed nerve interface integrating a biomimetic nanocomposite hydrogel with sustained delivery of thermostable FGF‐2. The bioactive interface supports Schwann cell activity and myelination while providing a regenerative microenvironment.

Modified robotic V‐Y plasty for post‐radical prostatectomy vesico‐urethral anastomotic stricture: Incorporating the Joshi step

UroPrecision, EarlyView.
Abstract Background Bladder neck contracture is a challenging complication following radical prostatectomy. While endoscopic management is the first line of treatment, recalcitrant cases often require surgical reconstruction. This report aimed to describe a minimally invasive technique for reconstructing post‐radical prostatectomy vesico‐urethral ...
