OBJECTIVE Crowdsourcing dietary ratings for food photographs, which uses the input of several users to provide feedback, has potential to assist with dietary self-monitoring. MATERIALS AND METHODS This study assessed how closely crowdsourced ratings of foods and beverages contained in 450 pictures from the Eatery mobile app as rated by peer users (fellow(More)
OBJECTIVE The aim of this study is to explore the spectral patterns of spontaneous magnetoencephalography (MEG) activity across the lifespan. APPROACH Relative power (RP) in six frequency bands (delta, theta, alpha, beta-1, beta-2 and gamma) was calculated in a sample of 220 healthy subjects with ages ranging from 7 to 84 years. MAIN RESULTS A(More)
Poor sleep quality is associated with chronic diseases, weight increase and cognitive dysfunction. Home monitoring solutions offer the possibility of offering tailored sleep coaching interventions. There are several new commercially available devices for tracking sleep, and although they have been tested in sleep laboratories, little is known about the(More)
– Sleep quality has an important impact in overall health. There are several new commercially available devices for sleep tracking. Although they have been tested in sleep laboratories, for some users, estimates are reliable whereas for others are very different. In this paper we present a framework to predict the error range of the total sleep time. We(More)
In recent years, a spectacular increase has taken place in the demand for techniques to improve the appearance of the skin, both for cosmetic and reparative purposes. The techniques used may have complications that interfere with the healing process, and therefore may affect the results from an aesthetic standpoint. The most significant complication is(More)
The aim of this study is to explore the capability of an Emfit (electromechanical film transducer) mattress to detect snoring (SN) by analyzing the spectral differences between normal breathing (NB) and SN. Episodes of representative NB and SN of a maximum of 10 min were visually selected for analysis from 33 subjects. To define the bands of interest, we(More)
