Temporal activity detection in untrimmed videos with recurrent neural networks

This work proposes a simple pipeline to classify and temporally localize activities in untrimmed videos. Our system uses features from a 3D Convolutional Neural Network (C3D) as input to train a a recurrent neural network (RNN) that learns to classify video clips of 16 frames. After clip prediction, we post-process the output of the RNN to assign a single activity label to each video, and determine the temporal boundaries of the activity within the video. We show how our system can achieve competitive results in both tasks with a simple architecture. We evaluate our method in the ActivityNet Challenge 2016, achieving a 0.5874 mAP and a 0.2237 mAP in the classification and detection tasks, respectively. Our code and models are publicly available at: https://imatge-upc.github.io/activitynet-2016-cvprw/Peer ReviewedPostprint (published version

The Spider Webs, an Alternative Strategy to Teach Elasticity

La tela de araña es una estructura sorprendente, sus propiedades físicas y químicas han despertado el interés de muchos científicos alrededor del mundo. En este artículo se propone una metodología alternativa, económica y relativamente simple de aplicar para estimar propiedades elásticas de las telas de arañas. Impulsando un método de enseñanza de la Física con aplicación biológica que permita a los alumnos comprender los conceptos de elasticidad de manera experimental y tangible.The spider web is a surprising structure, its physical and chemical properties have woken up the interest of many scientists around the world.

Vida en Clausura: estudio de las patentes de los ministros franciscanos conservadas en el archivo del Convento de Santa Clara de Borja (1603-1875)

Dentro de las últimas líneas de investigación impuestas por la actual perspectiva historiográfica en torno a la mujer, que han posibilitado un mejor conocimiento histórico del monacato femenino, sus modelos de vida y del comportamiento de la religiosidad femenina, se circunscribe este artículo en el que, a través de las patentes conservadas en el archivo del convento de Santa Clara de Borja (Zaragoza), se profundiza en las normas disciplinarias que rigieron en éste y los restantes conventos de la antigua Provincia de Aragón, así como en determinados aspectos de la vida cotidiana de estas clausuras.This contribution follows the most recent historiographical aproaches to gender studies, specially those linked to female monasticism. Recent studies have provided a better knowledge of life models and female religious attitudes. In this case-study, patent certificates preserved in the archives of the Convent of Santa Clara (Borja, Saragossa) are used in order to analyze the disciplinary rules which governed this community. The paper provides also an in-depth description to other specific aspects of the daily life in Santa Clara and other monasteries of the former Franciscan Province of Aragon in northeastern Spain

Implications of apixaban for dental treatments

Anticoagulation therapy is used in several conditions to prevent or treat thromboembolism. Recently, new oral anticoagulants have been introduced as alternatives to warfarin and acenocoumarol. In Europe, the European Medicines Agency has approved dabigatran, rivaroxaban and apixaban. Their advantages include: predictable pharmacokinetics, drug interactions and limited food, rapid onset of action and short half-life. However, they lack a specific reversal agent. A literature search was conducted through November 2015 for publications in the ISI Web of Knowledge, PubMed, Scopus and Cochrane Library using the keywords “apixaban”, “rivaroxaban”, “dabigatran”, “new oral anticoagulants”, “dental treatment” and “dental implications”. We included studies published in English and Spanish over the last 10 years. Apixaban has been recently introduced in the daily medical practices for the control of thromboembolism. The number of patients taking apixaban is increasing. Management of patients on anticoagulation therapy requires that dentists can accurately assess the patient prior to dental treatments. It is important for dentists to have a sound understanding of the mechanisms of action and management guidelines for patients taking new oral anticoagulants. The dentist should consider carefully the management of patients on apixaban. This paper sets out a clinical guidance of dental practitioners treating these patients. There is a need for further clinical studies in order to establish more evidence-based guidelines for dental patients requiring apixaban

«Modicæ fidei quare dubitasti?» Una lectura del pontificado de Calixto III (1455-?1458) a partir de las imágenes monetales

This article studies the pontificate of Calixtus III (1455-?1458) from the propaganda function and communicational dimension of the images and inscriptions appearing on papal coinage. Attention is paid to points of continuity with the monetary issues of his predecessors on the throne of St. Peter, as well as novelties introduced in relation to the planned crusade against Islam. Keywords: Calixtus III, Numismatics, Medals, pontifical mints, propagand

¿Son útiles las “métricas espaciales fragstats” para caracterizar entornos de movilidad urbanos?

El objetivo de alcanzar una mayor sostenibilidad ambiental en la planificación del transporte urbano ha sido una de las principales razones del desarrollo de conceptos, métodos y herramientas orientadas a vincular de manera efectiva la estructura urbana y el sistema de transporte. En este contexto, surgen los “entornos de movilidad” como instrumentos integrados de planificación con éxitos notables en diferentes ámbitos escalares y contextuales. Los “entornos de movilidad” son concebidos como unidades geográficas para la planificación y definidos por una triple componente: (i) estructura urbana o componente física; (ii) accesibilidad o componente móvil; (iii) interacción humana o componente social. La presente comunicación explora algunas de las herramientas para caracterizar la componente física o de estructura urbana, concretamente las métricas espaciales de ventana móvil, que son aplicadas sobre un conjunto de “entornos de movilidad” previamente definidos para el Área Metropolitana de Granada. La idoneidad de estas métricas para la caracterización espacial de los entornos se ha analizado mediante la determinación de la significación estadística de las diferencias de los valores obtenidos. Los resultados han mostrado que entre las métricas utilizadas, la relativa a conectividad de espacios verdes es la que ha permitido discriminar mejor los “entornos de movilidad”. Por el contrario, las métricas relativas a la proximidad y diversidad de los usos urbanos presentan más dificultad para identificar con claridad las diferencias existentes entre unos “entornos de movilidad” y otros. Este hecho sugiere la necesidad de continuar profundizando sobre la relación entre las características espaciales de los “entornos de movilidad” y las métricas que pueden ser más idóneas para su identificación y posterior uso en la práctica diaria de la planificación

Dental management of patients taking novel oral anticoagulants (NOAs): dabigatran

A new group of oral anticoagulants (dabigatran, rivaroxaban, apixaban and edoxaban) with clear advantages over classic dicoumarin oral anticoagulants (warfarin and acenocoumarol) has been developed in recent years. Patients being treated with oral anticoagulants are at higher risk for bleeding when undergoing dental treatments. A literature search was conducted through April 2016 for publications in the ISI Web of Knowledge, PubMed and Cochrane Library using the keywords “dabigatran”, “rivaroxaban”, “apixaban”, “edoxaban”, “new oral anticoagulants”, “novel oral anticoagulants”, “bleeding” and “dental treatment”. There is no need for regular coagulation monitoring of patients on dabigatran therapy. Whether or not to temporarily discontinue dabigatran must be assessed according to the bleeding risk involved in the dental procedure to be performed. The number of patients under treatment with new oral anticoagulants will increase in the coming years. It is essential to know about the pharmacokinetics and pharmacodynamics of new oral anticoagulants and about their interactions with other drugs. It is necessary to develop clinical guidelines for the perioperative and postoperative management of these new oral anticoagulants in oral surgical procedures, and to carefully evaluate the bleeding risk of dental treatment, as well as the thrombotic risk of suppressing the new oral anticoagulant
