Beyond the Camera Trap: A Systematic Review of Computing Technology Used to Monitor and Interact with (More) Varied Taxa in Zoos and Aquariums

open access: yesAnimals
Zoos and aquariums house a wide range of species, yet research remains heavily skewed toward mammals and camera-based technologies. This systematic literature review examines the use of computing technologies to monitor or interact with animals in zoos ...

Measuring straightness errors of slender shafts based on coded references and geometric constraints

open access: yesThe Journal of Engineering, 2020
The coded references and geometric constraints based method is suggested to solve the inconsistency problem of measurement range and accuracy for slender shafts. First, a slender shaft is divided into segments.

VID: Human identification through vein patterns captured from commodity depth cameras

open access: yesIET Biometrics, 2021
Herein, a human identification system for smart spaces called Vein‐ID (referred to as VID) is presented, which leverage the uniqueness of vein patterns embedded in dorsum of an individual's hand. VID extracts vein patterns using the depth information and

Event-Based Motion Segmentation by Motion Compensation [PDF]

open access: yes, 2019
In contrast to traditional cameras, whose pixels have a common exposure time, event-based cameras are novel bio-inspired sensors whose pixels work independently and asynchronously output intensity changes (called "events"), with microsecond resolution ...

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.
