Remote sensing of the reflectance photoplethysmogram using a video camera typically
positioned 1 m away from the patient's face is a promising method for monitoring the vital signs of …

Since its emergence in late 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
has caused a pandemic with more than 55 million reported cases and 1.3 million …

Novelty detection is the task of classifying test data that differ in some respect from the data
that are available during training. This may be seen as “one-class classification”, in which a …

This review provides an introduction to the use of parametric modelling techniques for time
series analysis, and in particular the application of autoregressive modelling to the analysis …

Breast cancer is the major cause of death amongst women in the 35 to 55 age group.

A dynamical model based on three coupled ordinary differential equations is introduced which
is capable of generating realistic synthetic electrocardiogram (ECG) signals. The operator …

Background Although heart rate and respiratory rate in children are measured routinely in
acute settings, current reference ranges are not based on evidence. We aimed to derive new …

The identification of the exact positions of the first and second heart sounds within a
phonocardiogram (PCG), or heart sound segmentation, is an essential step in the automatic analysis …

Neural networks have shown enormous potential for commercial exploitation over the last
few years but it is easy to overestimate their capabilities. A few simple algorithms will learn …
