Soil respiration signals in response to sustainable soil management practices enhance soil organic carbon stocks [PDF]

arXiv
Development of a spatial-temporal and data-driven model of soil respiration at the global scale based on soil temperature, yearly soil moisture, and soil organic carbon (C) estimates. Prediction of soil respiration on an annual basis (1991-2018) with relatively high accuracy (NSE 0.69, CCC 0.82).

SiNC+: Adaptive Camera-Based Vitals with Unsupervised Learning of Periodic Signals [PDF]

arXiv
Subtle periodic signals, such as blood volume pulse and respiration, can be extracted from RGB video, enabling noncontact health monitoring at low cost. Advancements in remote pulse estimation -- or remote photoplethysmography (rPPG) -- are currently driven by deep learning solutions.

Non-Invasive Monitoring of Vital Signs in Calves Using Thermal Imaging Technology [PDF]

arXiv
This study presents a non-invasive method using thermal imaging to estimate heart and respiration rates in calves, avoiding the stress from wearables. Using Kernelised Correlation Filters (KCF) for movement tracking and advanced signal processing, we targeted one ROI for respiration and four for heart rate based on their thermal correlation.

Harmonic MUSIC Method for mmWave Radar-based Vital Sign Estimation [PDF]

arXiv
This paper investigates the application of millimeter-wave (mmWave) radar for the estimation of human vital signs. Aiming to obtain more accurate frequency estimation for periodic signals of respiration and heartbeat, we propose the harmonic MUSIC (HMUSIC) algorithm to consider harmonic components for frequency estimation of vital sign signals.
