TRANS-FUSIMO: preliminary in-vivo animal results of MR-guided focused ultrasound of liver under respiratory motion
2019
Purpose: Treating liver tumors using Focused Ultrasound (FUS) is a great challenge. Prior to human applications, an in-vivo animal trial using the TRANS-FUSIMO treatment system (TTS) is ongoing in order to evaluate the safety and the technical efficacy and efficiency of generating predefined necrotic lesions. Methods and Materials: The trial includes a crossbred porcine model of thirty large white swine (all females; 55-85Kg) that will be treated using the TTS under general anaesthesia with intubation. All treatments haven been performed under ventilator-controlled breathing and using an improved non-clinical prototype FUS transducer integrated with a 1,5T MRI unit; a set of interventional …
Food-Based Dietary Guidelines around the World: A Comparative Analysis to Update AESAN Scientific Committee Dietary Recommendations
2021
Food-Based Dietary Guidelines (FBDG) include dietary recommendations based on food groups according to the general and accepted nutrition principles and current scientific evidence. Adoption of FBDG contributes to the prevention of malnutrition in all its forms, promotes human health, and reduces environmental impact. The present review aims to perform an international comparative analysis of the FBDG adopted in different countries from three different continents (America, Asia, and Europe), with particular reference to the Spanish Food Safety and Nutrition Agency (AESAN, Agencia Española de Seguridad Alimentaria y Nutrición) Scientific Committee dietary recommendations. A total of twelve c…
Prediction of active peak force using a multilayer perceptron
2017
Both kinematic parameters and ground reaction forces (GRFs) are necessary for understanding the biomechanics of running. Kinematic information of a runner is typically measured by a motion capture system whereas GRF during the support phase of running is measured by force platforms. To analyze both kinematics and kinetics of a runner over several subsequent contacts, an instrumented treadmill or alternatively several force platforms installed over a regulated space are available options, but they are highly immovable, expensive, and sometimes even impractical options. Naturally, it would be highly useful to predict GRFs using a motion capture system only and this way reduce costs and comple…
Los centros de formación y educación profesional: una alternativa para el desarrollo local.
2014
Este artículo presenta una propuesta educativa de índole técnico pero con bases enraizadas en la educación popular (Freire, 1970). La misma pretende dar luces de cómo la educación profesional podría tener una vinculación para el desarrollo local del territorio. El desarrollo local tiene sus máximos exponentes en los ámbitos de la recuperación de las fuentes endógenas y en la articulación del tejido asociativo (Herrera, 2009), con el consecuente beneficio de la potenciación de instrumentos participativos que mejoren los intercambios democráticos del territorio. Los centros educativos pueden tener una visión privilegiada del territorio, ya que confluyen en el mismo algunos elementos, actores …
Mobilités et trajectoires dans la galaxie des professions intermédiaires
2012
en ligne sur : http://www.cereq.fr/index.php/content/download/4871/44628/file/Relief37.pdf; National audience; Comment les professions intermédiaires se positionnent-elles au sein des entreprises au regard des mobilités et des frontières avec les autres catégories ? Cette communication s'appuie sur l'analyse des discours de salariés et de responsables d'entreprise interviewés dans une vingtaine d'établissements de divers secteurs d'activité, et se décline en trois sections. La première illustre les contours flous de ces métiers sous le double aspect des perceptions des personnes et des contraintes patronales de gestion des ressources humaines. La deuxième partie apporte un éclairage sur l'a…
Mākslas darbu apropriācijas kā ierosmes avots vizuālās mākslas stundās
2015
Diplomdarba tēma – Apropriācija kā ierosmes avots vizuālās mākslas stundās. Apropriācija ir mūsdienīgs mākslas darbu radīšanas veids, kurā mākslinieki, balstoties uz jau esošajiem mākslas darbiem, rada jaunus saturiski atšķirīgus darbus. Iepazīstot un izmantojot apropriāciju vizuālās mākslas stundās, skolēniem ir iespēja apgūt veidu kā izmantot esošos mākslas darbus, lai radītu jaunus, kā arī apropriācijas procesā iepazītu dažādus māksliniekus, stilus un izzinātu mākslas darba saturisko un vizuālo nozīmi. Lai īstenotu diplomdarbā izvirzīto mērķi - atklāt apropriācijas nozīmi mākslas darba izpratnē un jauna darba radīšanā vizuālās mākslas stundās, autore izpētīja apropriācijas jēdziena dažād…
That Crazy World We’ll Live in : Emotions and Anticipations of Radical Future Technology Design
2020
Humans behave towards and experience technological design in conflicting and contradictory ways. On the one hand, the very mention of the word ‘future’ conjures expectations of the radically new and unexpected. On the other hand, previous research has shown that people have a threshold for the level of change and the unexpected that they can cope with. Their expectations are dominated by mental images of familiar associations with what has been previously associated with the future. As a rule, humans cope with incremental changes, yet have difficulty accepting the entirely unfamiliar. This makes it harder to imagine a future of radical technology design and interactions, particularly when a…
Characteristics of regular gamblers in Italy: The role of control and emotion regulation
2016
Objective: the main purpose of this study is to investigate the emotional and temperamental characteristics associated with gambling in Italy and to compare different groups of people on the basis of their risk of gambling: low-risk gamblers, problem gamblers, and pathological gamblers. Particularly, we examined the possible discriminant functions of perception of control, locus of control (whether internal or chance-based; that is, devoted to fate), and emotion-regulation strategies (cognitive reappraisal and expressive suppression). Method: a total of 251 adult regular gamblers (142 males and 109 females) recruited from different betting and bingo halls completed self-report questionnaire…
Density flow over networks: A mean-field game theoretic approach
2014
A distributed routing control algorithm for dynamic networks has recently been presented in the literature. The networks were modeled using time evolution of density at network edges and the routing control algorithm allowed edge density to converge to a Wardrop equilibrium, which was characterized by an equal traffic density on all used paths. We borrow the idea and rearrange the density model to recast the problem within the framework of mean-field games. The contribution of this paper is three-fold. First, we provide a mean-field game formulation of the problem at hand. Second, we illustrate an extended state space solution approach. Third, we study the stochastic case where the density …
Modulation of attention by socio-emotional scenes in children with autism spectrum disorder
2017
Background: Abnormal attentional processes to socially relevant information may underlie social impairment in Autism Spectrum Disorder (ASD). To examine how these processes are modulated by the emotional salience of the stimuli, we studied the attentional biases to social scenes (happy, sad, and threatening) in ASD children. Method: An emotional dot-probe task was applied to children (from 6 to 12 years old) with Autism Spectrum Disorder without additional language and/or intellectual impairments (ASD; n=25) and age/sex-matched controls (n=25). Results: ASD children showed an attentional bias toward threatening scenes while typically developing children tended to direct their attention towa…
