Ultra-wideband Radar Detection of Breathing Rate: A Comparative Evaluation
… (UWB) radar based device to detect breathing rate for health monitoring applications. Health monitoring devices observe physiological signals to detect medical conditions. We focus on capturing the small mechanical movements caused by breathing. This is traditionally done via a …

Monitoring Breathing Using a Doppler Radar
… received by a Doppler radar to estimate the breathing rate from the detected motion associated with breathing. A reliability measure is provided with breathing rate estimates through the analysis of various signal quality indices. Results demonstrate that the algorithm is able to estimate the …

Decoupling Motion from Sensory Data: An Emergent Property of a Neural Population in the Piriform Cortex
Modulation of breathing rate is crucial to flexibly explore the olfactory environment. Inhalation gates the perception of scents, and the act of sniffing is necessary for the olfactory percept. In olfaction, sniffing increases the airflow velocity inside the nostrils and the number of odor …

Measuring and evaluating physical strain to improve construction workforce productivity
… vs. productivity relationship by adopting heart rate and breathing rate as predictors of physical strain. Thus, productivity, heart rate, and breathing rate data of nine subjects performing a four-hour, simulated construction task (i.e., over 30 hours of recorded data with sampling frequency of 1 …

Pulmonary Particle Deposition in Relation to Age, Body Weight, and Species
… and deposition increase. Also, for all ages, breathing rates that are lower than normal enhance volume-weighted deposition and shift optimal particle size. Additionally, a rigorous sensitivity analysis of breathing rate and particles diameter on deposition shows that at normal breathing rates, …

The Effects of Hypobaric Pressure on Thermoregulation in The Unrestrained New Zealand White Rabbit, Oryctolagus Cuniculus
… back temperature, preoptic temperature, breathing rate and heart rate.

BioResonant interfaces : tangible, subliminal biofeedback to regulate physiological states
… a kinetic display, which utilize either heart rate (HR) or breathing rate (BR), or both. I present their fabrication, design, and evaluation method in the following interaction scale order: local interaction with the skin; general interaction with the body; and embodied interaction with the …

Shared Creativity and Flow in Dance Improvisation Practice
… 203 participants (77 experts and 126 nonexperts) rated excerpts of high- and low-flow dance improvisation (five each) using Consensual Assessment Technique. Experts judged high-flow collaborations as more creative, and more coherent, technically advanced, aesthetically appealing and meaningful, …

Just Add Monsters: Stressful Biofeedback Games for Improved Physiological Control
… explicitly physiological sensation: an increased breathing rate, sweaty palms, and a racing heart which can precede, co-occur with, and follow stressful experiences. The bi-directional relationship between these physiological responses and their subjective experiences suggests that physiology …

Automated open circuit scuba diver detection with low cost passive sonar and machine learning
… systems required matching the frequency of diver breathing transients to that of an assumed diver breathing frequency. Earlier work required prior knowledge of both the number of divers and their breathing rate. Here an image processing approach is used for automated diver detection by …

Camera-based Recovery of Cardiovascular Signals from Unconstrained Face Videos Using an Attention Network
… results in estimating vital signs such as heart rate and breathing rate. However, recovering the instantaneous pulse rate signals is still a challenge for the community. This is due to the fact that most of the previous methods concentrate on capturing the temporal average of the cardiovascular …

Respiratory Biomarkers in Kv1.1 Knockout Mice, a Model for Temporal Lobe Epilepsy
… Death in Epilepsy (SUDEP). We recently demonstrated the progressive nature of epilepsy and mortality in Kv1.1 knockout (KO) mice, a model of temporal lobe epilepsy and SUDEP. We reported respiratory abnormalities in KO mice using the methacholine (MCh) challenge, indicating that increased …

The effect of cis-platinum alone or in combination with radiation on mouse lung
… the release of pulmonary surfactant, changes in breathing rate, a histology based score of damage and changes in TGF-β - a cytokine important in the development of fibrosis. Single doses of either cis-platinum or radiation, cis-platinum given immediately before a single dose of radiation, …

City browser : a user study to optimize a naturalistic voice navigation system
… over 90 participants. Each subject was also separated into different demographic groups as to quantify the difference of age and gender on system interaction. During the course of the experiment, three different forms of data collection were obtained: self report questionnaires, audio recordings, …

Radon, progeny and health: investigation in different environments in Northamptonshire
… of intake to the respiratory system from reduced breathing rate during the sleep mode. Potentially also, from the mechanism postulated which implies the limitation of the impact of alpha particles, related to an association between water vapour pressure, radon and particulates in the atmosphere. …

Wearable sensor systems to study the physiological and behavioral manifestation of cigarette smoking in free-living
… these harms, smokers often struggle to quit. Accurate information on daily smoking might help for evaluating the smoking behavior of an individual and the effectiveness of related intervention process. Self-reporting, puff topography meters, and biomarkers are the primary tools available for the …

"Sweet Hearts": A biokinetics primary prevention programme in the South African public health sector: A qualitiative analysis
… These findings support the notion that multi-strategic community-wide interventions are able to reach a large proportion of the population regardless of social class and socioeconomic level. Broad-based instead of individual interventions are more cost-effective and help to spread knowledge …
