Curación de contenidos desde bibliotecas: competencias, herramientas y aplicaciones

In the Age of Big Data we have at our disposal a great amount of information in different formats and from websites, repositories, blogs, databases, digitized files and documentary sources of all kinds, which presents a great challenge for the management and the analysis of the information that we apply day by day in our personal and labor scope. Given the difficulty of organizing and optimizing all this data flow, the content curator emerges as an intermediary of knowledge that discriminates against “informational waste” and facilitates quality on the web through search, selection and dissemination of content. Virtual environments permanently extend and complement the library’s services in time and space so it is necessary to think of activities and contents that are digital in order to capture the confidence of new users and reinforce their operational and informational capacities and competences through the new generation of technological applications that have emerged in recent years. From this premise, we analyze the origin and basic characteristics of this new professional profile, as well as the proposals and functionalities related

Development of a Virtual Bluetooth Escape Room For Android Devices

Treball final de Grau en Disseny i Desenvolupament de Videojocs. Codi: VJ1241. Curs acadèmic: 2020/2021This document presents the Final Degree Project in Video Game Design and Development. The work to be developed consists of the creation of a videogame for mobile devices in Escape Room format using Bluetooth beacons. The player will have to solve the puzzles that are distributed in the different rooms of the videogame by interacting in different ways with the screen and the environment, changing the room when approaching the beacon associated with it

The Case for a National Assessment on Landmine Contamination through NTS in Colombia

With a majority of Colombia’s municipalities reporting landmine or ordnance incidents since 1990, there is an urgent need to perform non-technical survey (NTS) in the country to determine the remaining threat. Assuming liability for risk, howevr, slows the process. The authors make a case for proceeding with NTS

Novel Antioxidant Therapy Against Myocardial Ischemia– Reperfusion Injury During Percutaneous Coronary Angioplasty

Acute myocardial infarction (AMI) is the leading cause of mortality worldwide. Major advances in the treatment have included coronary interventions, such as systemic thrombolysis and percutaneous coronary angioplasty (PCA). These procedures have been aimed to recover the blood flow in the cardiac zones affected by the occlusion of a branch of the coronary artery. However, damage is generated in the heart tissue known as myocardial reperfusion injury, an event associated with increased oxidative stress. Reactive oxygen species (ROS) are able to trigger cell death pathways, and myocardial structural and functional impairment. Studies on animal models of AMI suggest that lethal reperfusion accounts for up to 50% of the final size of a myocardial infarct, a part of the damage likely to be prevented. Although a number of strategies have been aimed to ameliorate lethal reperfusion injury, up to date the beneficial effects in clinical settings remain elusive. The accumulated body of evidence suggests that redox balance is a crucial determinant of ischemia–reperfusion injury, with clear mechanistic insights into pharmacological approaches. This chapter presents the molecular basis for a novel cardioprotection of patients with AMI subjected to PCA, based on a reinforcement of the antioxidant system

Continuum limit for a discrete Hodge-Dirac operator on square lattices

We study the continuum limit for Dirac-Hodge operators defined on the $n$ dimensional square lattice $h\mathbb{Z}^n$ as $h$ goes to $0$. This result extends to a first order discrete differential operator the known convergence of discrete Schr\"odinger operators to their continuous counterpart. To be able to define such a discrete analog, we start by defining an alternative framework for a higher-dimensional discrete differential calculus. We believe that this framework, that generalize the standard one defined on simplicial complexes, could be of independent interest. We then express our operator as a differential operator acting on discrete forms to finally be able to show the limit to the continuous Dirac-Hodge operator

IEDs: A Major Threat for a Struggling Society

The use of improvised explosive devices by guerrillas, drug cartels and paramilitary groups has threatened Colombian society for the past 30 years. This article examines the types of IEDs found in Colombia, and the extent and history of its IED problem. Also outlined are the Colombian government’s efforts to counter IEDs, and possible solutions to the challenges ahead, such as enhanced intelligence and community security

Comparing Neural and Attractiveness-based Visual Features for Artwork Recommendation

Advances in image processing and computer vision in the latest years have brought about the use of visual features in artwork recommendation. Recent works have shown that visual features obtained from pre-trained deep neural networks (DNNs) perform very well for recommending digital art. Other recent works have shown that explicit visual features (EVF) based on attractiveness can perform well in preference prediction tasks, but no previous work has compared DNN features versus specific attractiveness-based visual features (e.g. brightness, texture) in terms of recommendation performance. In this work, we study and compare the performance of DNN and EVF features for the purpose of physical artwork recommendation using transactional data from UGallery, an online store of physical paintings. In addition, we perform an exploratory analysis to understand if DNN embedded features have some relation with certain EVF. Our results show that DNN features outperform EVF, that certain EVF features are more suited for physical artwork recommendation and, finally, we show evidence that certain neurons in the DNN might be partially encoding visual features such as brightness, providing an opportunity for explaining recommendations based on visual neural models.Comment: DLRS 2017 workshop, co-located at RecSys 201
