Cardiovascular Responses to Natural and Auditory Evoked Slow Waves Predict Post‐Sleep Cardiac Function

Journal of Sleep Research, EarlyView.
ABSTRACT The importance of sleep as a key component of cardiovascular health has been increasingly recognized. Our previous research demonstrated that auditory‐enhanced slow waves increase cardiac function, but the underlying mechanisms behind these beneficial effects remain uncertain. In this study, we examined the influence of two types of slow waves

Real-time capable micro-Doppler signature decomposition of walking human limbs

, 2022
S.1093-1098Unique micro-Doppler signature (m-D) of a human body motion can be analyzed as the superposition of different body parts m-D signatures. Extraction of human limbs m-D signatures in real-time can be used to detect, classify and track human ...

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]

, 2012
We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.

Quantifying microvascular responses to local heating using optical coherence tomography: Comparison between skin sites and sex differences

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 ...

Effect of chronic high‐altitude hypoxia on retinal vascular phenotype, choroidal and retinal vasoreactivity in Peruvian highlanders

Experimental Physiology, EarlyView.
Abstract High‐altitude chronic hypoxia can induce excessive erythrocytosis (EE, defined as a haemoglobin concentration of ≥21 g/dL in men), leading to hyperviscosity and promoting endothelial dysfunction. We aimed to assess whether EE affects the retinal vascular phenotype and the ophthalmological vascular response to CO2.

Multistatic micro-Doppler radar signatures of personnel targets

, 2016
This study extends the theory of the micro-Doppler effect into the multistatic domain, and considers how the multistatic micro-Doppler signature (μ-DS) will affect radar automatic target recognition (ATR).

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 Science
Current 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 ...

Proliferative Sparganosis Due to Spirometra mansoni in a Dog: A Detailed Diagnostic Picture

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Innumerable small oval cystic structures were identified in the peritoneal cavity of a young dog presenting with abdominal distension and weight gain. A combination of diagnostics confirmed these structures as Spirometra mansoni plerocercoids and established a diagnosis of proliferative sparganosis.
