Demographic Differences in the Effectiveness of a Physical Activity Application to Promote Physical Activity: Study Among Aged People
2021
The global population is ageing and simultaneously the life expectancy at older ages is improving. To support healthy and active aging, it is imperative to find solutions to support physical activity (PA) in older age. Digital wellness technologies are a potential solution, but in order for such technologies to be successful, research is needed to gain a better understanding on their use and effectiveness among aged people. To address this need, this study investigated the effectiveness of a physical activity application to promote PA behavior among aged people of different demographics (gender, age, education, marital status). PA levels were measured before taking the application into use …
A User-Centered Chatbot (Wakamola) to Collect Linked Data in Population Networks to Support Studies of Overweight and Obesity Causes: Design and Pilo…
2021
[EN] Background: Obesity and overweight are a serious health problem worldwide with multiple and connected causes. Simultaneously, chatbots are becoming increasingly popular as a way to interact with users in mobile health apps. Objective: This study reports the user-centered design and feasibility study of a chatbot to collect linked data to support the study of individual and social overweight and obesity causes in populations. Methods: We first studied the users' needs and gathered users' graphical preferences through an open survey on 52 wireframes designed by 150 design students; it also included questions about sociodemographics, diet and activity habits, the need for overweight and o…
Gesture recognition using low-cost devices: Techniques, applications, perspectives
2016
Negli ultimi anni abbiamo assistito ad una grande diffusione dei cosiddetti “Kinect-like devices”, ovvero dispositivi basati su un insieme di sensori a basso costo, che consentono di ottenere un’immagine di profondità della scena ripresa. L’alta accessibilità di questi dispositivi, principalmente in termini di costi, ne ha facilitato la diffusione nell’ambito del riconoscimento dei gesti in numerose applicazioni, sia commerciali che di ricerca. In questo articolo saranno inizialmente illustrati i principi generali su cui si fondano le principali tecniche utilizzate per riconoscere i gesti, sfruttando i dati ottenibili dai dispositivi “Kinect-like”. Successivamente, saranno presentati alcuni…
An in vitro comparison of different adhesive strategies on the micro push-out bond strength of a glass fiber post
2010
Objectives: To evaluate in vitro the push-out bond strengths of a glass fiber post adhesively luted with self-etching resin based and self-adhesive luting cements, as well as modified application procedure of self-adhesive luting cements in combination with single step self-etch adhesives. Materials and methods: Fifty single-rooted human maxillary central incisor teeth were endodontically treated and divided into five groups (n=10). Glass fiber posts (RelyX Fiber Post) were cemented with the following materials: group 1: ED Primer II/Panavia F 2.0 (PAN); group 2: RelyX Unicem (RU); group 3: Maxcem (MC); group 4: Adper Prompt L-Pop (PLP)/RelyX Unicem; group 5: Optibond all-in-one (OB)/Maxcem…
A methodology to estimate forest fires burned areas and burn severity degrees using Sentinel-2 data. Application to the October 2017 fires in the Ibe…
2021
Abstract A methodology to estimate the extent of areas affected by forest fires, as well as the burn severity levels using Sentinel 2 images (10 and 20 m) is proposed and applied to the fires occurred in October 2017 in Spain and Portugal. An extension larger than 250,000 ha and 4 burn severity levels (low, moderate, high and very high) have been obtained. The comparison with the European Forest Fire Information System (EFFIS), which uses MODIS images (250 m), shows that the methodology improves the area estimate by 10 % in commission area. In terms of burn severity levels, the Separability index (SI) and the Kappa statistic (k) show a high correlation between Sentinel-2 and EFFIS (SI value…

La perspectiva de la sostenibilidad en la sociedad del conocimiento interconectado: gobernanza, educación, ética
2013
El presente artículo pretende estimular la reflexión sobre la introducción de la perspectiva de la sostenibilidad en las nuevas sociedades de la información y del conocimiento sustentadas por las TIC, y caracterizadas por una globalización que dista mucho de ser inclusiva. Implica la construcción de un sistema mundial que promueva la búsqueda de la calidad ambiental, la justicia social y una economía equitativa y viable a largo plazo. La UNESCO ha señalado tres caminos básicos para conseguirlo: la gobernanza, la educación y la éticaLa gobernanza puede propiciar una conectividad social equitativa, cambios en los modelos de producción y consumo y la búsqueda y aplicación de soluciones reales …
Diabetes and Ischemic Stroke: An Old and New Relationship an Overview of the Close Interaction between These Diseases
2022
Diabetes mellitus is a comprehensive expression to identify a condition of chronic hyperglycemia whose causes derive from different metabolic disorders characterized by altered insulin secretion or faulty insulin effect on its targets or often both mechanisms. Diabetes and atherosclerosis are, from the point of view of cardio- and cerebrovascular risk, two complementary diseases. Beyond shared aspects such as inflammation and oxidative stress, there are multiple molecular mechanisms by which they feed off each other: chronic hyperglycemia and advanced glycosylation end-products (AGE) promote ‘accelerated atherosclerosis’ through the induction of endothelial damage and cellular dysfunction. …

The baculovirus display technology--an evolving instrument for molecular screening and drug delivery.
2008
High throughput screening is a core technology in drug discovery. During the past decade, several strategies have been developed to screen (poly)peptide libraries for diverse applications including disease diagnosis and profiling, imaging, as well as therapy. The recently established baculovirus display vector system (BDVS) represents a eukaryotic screening platform that combines the positive attributes of both cell and virus-based display approaches, allowing presentation of complex polypeptides on cellular and viral surfaces. Compared to microbial display systems, the BDVS has the advantage of correct protein folding and post-translational modifications similar to those in mammals, facili…
