Recorregut de recerca geològica i mineralògica per les comarques de l´Alta Cerdanya i del Capcir (Catalunya Nord): des de la Quingueta d´Ix a Angostrina – Vilanova de les Escaldes, Targasona, Font Romeu, a Mont-lluis i a la Bollosa
No full textRecorregut realitzat el 6 de juliol del 2014. El recorregut del present itinerari, es desenvoluparà quasi íntegrament pel Sistema Pirinenc; distribuint-se tant per diferents sectors d´aquesta serralada. Així, s´iniciarà a la Depressió de la Cerdanya – Capcir, per entrar després a la denominada Zona Axial del Sistema Pirinenc. Tanmateix, es circularà cap a la fi del recorregut, per les proximitats de la Zona Nord – Pirinenca. Així el recorregut de l’itinerari s’iniciarà a la població de la Guingueta d´Ix (o Bourmadame), per on es farà la primera parada. Després, el recorregut es dirigirà cap al poble de Angostrina – Vilanova de les Escaldes, prop d´on es farà una nova aturada. Després es dirigirà cap a Targasona, Font Romeu i Mont-Lluis. Després, es dirigirà cap el Nord, per tal d´arribar al llac de la Bollosa, per on es farà la darrera aturada d´aquest itinerari. Els trams inicials d´aquest recorregut s’haurà fet per la Depressió de la Cerdanya – Capcir, tot i que haurà transitat prop de la Zona Axial Pirinenca en diferents parts d´aquest recorregut. Així, inicialment es tallaran els materials cenozoics que reblen l´esmentada depressió. Posteriorment, es veuran afloraments de les roques granítiques, així com afloraments dels materials paleozoics, en circular per la Zona Axial Pirinenca

Persistent atrial fibrillation vs paroxysmal atrial fibrillation: differences in management
No full textA probabilistic author-centered model for Twitter discussions
No full textIn a recent work some of the authors have developed an argumentative approach for discovering relevant opinions in Twitter discussions with probabilistic valued relationships. Given a Twitter discussion, the system builds an argument graph where each node denotes a tweet and each edge denotes a criticism relationship between a pair of tweets of the discussion. Relationships between tweets are associated with a probability value, indicating the uncertainty that the relationships hold. In this work we introduce and investigate a natural extension of the representation model, referred as probabilistic author-centered model, in which tweets within a discussion are grouped by authors, in such a way that tweets of a same author describe his/her opinion in the discussion and are rep- resented with a single node in the graph, and criticism relationships denote controversies between opinions of Twitter users in the discussion. In this new model, the interactions between authors can give rise to circular criticism relationships, and the probability of one opinion criticizing another has to be evaluated from the probabilities of criticism among the tweets that compose both opinions.This work was partially funded by the Spanish MICINN Projects TIN2015-71799-C2-1-P and TIN2015-71799-C2-2-PPeer Reviewe
Posterior Coronary Vein as the Substrate for an Epicardial Accessory Pathway
No full textAbstractCatheter ablation of Wolff-Parkinson-White syndrome is associated with up to 5% of failure. Coronary sinus (CS) abnormalities or connections between CS myocardial coat and left ventricular epicardium are associated with posteroseptal and left posterior accessory pathways (AP). A 41-year-old patient with WPW syndrome was referred to our hospital after three unsuccessful ablations. The 12-lead ECG suggested a left posteroseptal AP. CT imaging and electro-anatomic mapping showed a relationship between AP electrical course and CS posterior branch. This finding supports the hypothesis CSAPs lie in the myocardial coat around CS and represent an extensive connection between atrial and ventricular epicardial surface
El pensamiento de santo Tomás de Aquino en la Encíclica Fides et ratio
No full textThe author presents the portrait of St. Thomas Aquinas following a selection of texts of the Encyclical. The harmony between faith and reason, the right autonomy of the human nature, the metaphysics of act of being (including the personal being) seem to be the ground of the recomendations of the Popes, particularly from Leo XIII to John Paul II, to study the thought of Aquinas, that was very present in the Council Vatican II
