Noninvasive Free Flap Monitoring Using Eulerian Video Magnification [PDF]
Case Reports in Otolaryngology, 2016 Eulerian Video Magnification (EVM) can enhance subtle changes in videos to reveal what was once invisible to the naked eye. In this proof of concept study, we investigated using EVM as a novel form of free flap monitoring.

Closing the air gap: the use of drones for studying wildlife ecophysiology. [PDF]
Biol Rev Camb Philos SocABSTRACT Techniques for non‐invasive sampling of ecophysiological data in wild animals have been developed in response to challenges associated with studying captive animals or using invasive methods. Of these, drones, also known as Unoccupied Aerial Vehicles (UAVs), and their associated sensors, have emerged as a promising tool in the ecophysiology ...
