Experimental Physiology, EarlyView.Summary of the study design, metholodgy, results and conclusions. Abstract Due to a lack of technical capacity to directly visualise and quantify microvessels in the skin, little is known regarding regional and/or sex differences. We compared diameter, velocity, flow and density at four regional sites using a novel optical coherence tomography (OCT ...

SRCNN: Stacked-Residual Convolutional Neural Network for Improving Human Activity Classification Based on Micro-Doppler Signatures of FMCW Radar [PDF]
Journal of Electromagnetic Engineering and ScienceCurrent methods for daily human activity classification primarily rely on optical images from cameras or wearable sensors. Despite their high detection reliability, camera-based approaches suffer from several drawbacks, such as low-light conditions ...

The Journal of Physiology, EarlyView.Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

Radar Micro-Doppler Signature Classification using Dynamic Time Warping
, 2016 This paper describes the first feasibility study using dynamic time warping (DTW) to classify the micro-Doppler signature (μ-DS ) for radar automatic target recognition (ATR). Real radar data has been used in the testing, and the performance of the DTW

Multiscale four‐dimensional imaging of cardiac remodelling after myocardial infarction
The Journal of Physiology, EarlyView.Abstract figure legend Multiscale 4D imaging framework for integrated phenotyping of post‐infarction remodelling. Myocardial infarction triggers dynamic changes across mechanical, haemodynamic and biological axes, progressing from acute injury and inflammation to extracellular matrix remodelling and scar maturation.
