Query expansion and semantic visualization in information system cooperations : methods and tools for information retrieval
2010
This thesis presents approaches and tools for information retrieval. Our work is part of a cooperation system based on ontologies called OWSCIS (Ontology and Web Service based Cooperation of Information Sources). We treat the problem of information retrieval by providing an enrichment method called QUEXME (QUery EXpansion MEthod) of queries based on analysis of user behavior and using the concept importance notion with regards to query. We also discussed the problem of visualization in the OWSCIS system offering a architecture of service visualization. It is composed of three modules: the request, enrichment and results. The approaches proposed in this thesis have been prototyped and the te…
Energy-Efficient Resource Allocation and User Scheduling for Collaborative Mobile Clouds With Hybrid Receivers
2016
In this paper, we study the resource allocation and user scheduling algorithm for minimizing the energy cost of data transmission in the context of OFDMA collaborative mobile cloud (CMC) with simultaneous wireless information and power transfer (SWIPT) receivers. The CMC, which consists of several collaborating MTs offers one potential solution for downlink con- tent distribution and for the energy consumption reduction at the terminal side. Meanwhile, as RF signal can carry both informa- tion and energy simultaneously, the induced SWIPT has gained much attention for energy efficiency design of mobile nodes. Previous work on the design of CMC system mainly focused on the cloud formulation o…
Peer Discipline and Incentives Within Groups
2014
We investigate how a collusive group can sustain non-Nash actions by enforcing internal discipline through costly peer punishment. We give a simple and tractable characterization of schemes that minimize discipline costs while preserving incentive compatibility. We apply the model to a public goods contribution problem. We find that if the per-capita benefit from the public good is low, then regardless of whether peer discipline is feasible or not only small groups will contribute to the good. If the public good benefit is significant but peer discipline is infeasible it remains the case that only small groups contribute. On the other hand, if the public good benefit is significant but peer…
How individual characteristics shape the structure of social networks
2015
Abstract We study how students’ social networks emerge by documenting systematic patterns in the process of friendship formation of incoming students; these students all start out in a new environment and thus jointly create a new social network. As a specific novelty, we consider cooperativeness, time and risk preferences – elicited experimentally – together with factors like socioeconomic and personality characteristics. We find a number of robust predictors of link formation and of the position within the social network (local and global network centrality). In particular, cooperativeness has a complex association with link formation. We also find evidence for homophily along several dim…
Short term association between ozone and mortality: global two stage time series study in 406 locations in 20 countries
2020
Objective To assess short term mortality risks and excess mortality associated with exposure to ozone in several cities worldwide. Design Two stage time series analysis. Setting 406 cities in 20 countries, with overlapping periods between 1985 and 2015, collected from the database of Multi-City Multi-Country Collaborative Research Network. Population Deaths for all causes or for external causes only registered in each city within the study period. Main outcome measures Daily total mortality (all or non-external causes only). Results A total of 45 165 171 deaths were analysed in the 406 cities. On average, a 10 µg/m3 increase in ozone during the current and previous day was associated with a…

Psychosocial factors related to the competitive anxiety of sports in training stages
2017
El objetivo de este trabajo es indagar la relación existente entre la ansiedad competitiva de futbolistas y tenistas en etapas de formación y la práctica de deporte por parte de los progenitores. Participaron en este estudio 246 niños deportistas de tenis y fútbol con una media de edad de 10,43 años (DT= 2,42), que han sido evaluados con un cuestionario de datos sociodemográficos y el cuestionario de Ansiedad Competitiva SAS-2 (Ramis, Torregrosa, Viladrich, & Cruz, 2010). Utilizando pruebas t de diferencias de medias independientes y pruebas no paramétricas, los resultados demuestran que los tenistas experimentan más ansiedad somática, mientras que los deportistas de menor edad presentan ma…
Diagnosis and management of AML in adults: 2017 ELN recommendations from an international expert panel
2017
Abstract The first edition of the European LeukemiaNet (ELN) recommendations for diagnosis and management of acute myeloid leukemia (AML) in adults, published in 2010, has found broad acceptance by physicians and investigators caring for patients with AML. Recent advances, for example, in the discovery of the genomic landscape of the disease, in the development of assays for genetic testing and for detecting minimal residual disease (MRD), as well as in the development of novel antileukemic agents, prompted an international panel to provide updated evidence- and expert opinion-based recommendations. The recommendations include a revised version of the ELN genetic categories, a proposal for …
