Analysing definition questions by two machine learning approaches

In automatic question answering, the identification of the correct target term (i.e. the term to define) in a definition question is critical since if the target term is not correctly identified, then all subsequent modules have no chance of providing relevant nuggets. In this paper, we present a method to tag a question sentence experimenting with two learning approaches: QTag and Hidden Markov Model. We tested the methods in five collections of questions, PILOT, TREC 2003, TREC 2004, CLEF 2004 and CLEF 2005. We performed ten-fold cross validation for each collection and we also tested with all questions together. The best accuracy rates for each collection were obtained using QTag, but with all questions together the best accuracy rate is obtained using HMM.IFIP International Conference on Artificial Intelligence in Theory and Practice - Speech and Natural LanguageRed de Universidades con Carreras en Informática (RedUNCI

Inversión pública y crecimiento económico. Una revisión crítica con propuesta de futuro

The relationship between public investment and economic performance has received a substantial attention by economists and policy-makers over the recent few years. In such a way, several approaches have been followed, from different theoretical and empirical points of view. The aim of this paper is to survey the main results found in the literature, especially those concerning productive public spending and economic growth. Moreover, we present a simple growth model in which regional characteristics are explicitly taken into account.Growth, infrastructures, regional policy

Public investment and growth: a survey

The relationship between public investment and economic is one of the most highly debated issues in economic policy circles in recent years. This topic has been analyzed from several approaches, both from a theoretical and empirical perspective. In this paper we present a survey of the main results found in the literature, with a special emphasis on those concerning productive public spending and economic growth.Growth, infrastructures, regional policy

H-P2PSIP: Interconnection of P2PSIP domains for Global Multimedia Services based on a Hierarchical DHT Overlay Network

The IETF P2PSIP WG is currently standardising a protocol for distributed mul- timedia services combining the media session functionality of SIP and the decentralised distribution and localisation of resources in peer-to-peer networks. The current P2PSIP scenarios only consider the infrastructure for the connectivity inside a single domain. This paper proposes an extension of the current work to a hierarchical multi-domain scenario: a two level hierarchical peer-to-peer overlay architecture for the interconnection of different P2PSIP domains. The purpose is the creation of a global decentralised multimedia services in enterprises, ISPs or community networks. We present a study of the Routing Performance and Routing State in the particular case of a two-level Distributed Hash Table Hierarchy that uses Kademlia. The study is supported by an analytical model and its validation by a peer-to-peer simulator.En prens

GlSch: Observation Scheduler for the GLORIA Telescope Network

This paper proposes the design and development of a scheduler for the GLORIA telescope network. This network, which main objective is to make astronomy closer to citizens in general, is formed by 18 telescopes spread over four continents and both hemispheres. Part of the management of this network is made by the network scheduler. It receives the observation requests made by the GLORIA users and then sends it to the most suitable telescope. A key module of the network scheduler is the telescope decision algorithm that makes possible to choose the best telescope, and thus avoiding offering an observation to a telescope that cannot execute it. This paper shows two different telescope decision algorithms: the first one is only based on weather forecast, meanwhile the second one uses fuzzy logic and information from each network telescope. Both algorithms were deployed in the GLORIA network. The achieved results coupled with a comparative of their performance is shown. Moreover, the network scheduler architecture, based on a hybrid distributed-centralized schema, is detailed.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Evaluación de las Reacciones Adversas Medicamentosas mediante farmacovigilancia en pacientes ingresados en las salas de Cirugía y Ortopedia del Hospital Regional Santiago de Jinotepe Octubre-Noviembre 2016

El presente estudio tiene como objeto evaluar mediante farmacovigilancia, las Reacciones Adversas Medicamentosas en pacientes ingresados en las salas de Cirugía y Ortopedia del Hospital Regional Santiago de Jinotepe, Octubre-Noviembre 2016. Es un estudio de tipo descriptivo, prospectivo y de corte longitudinal, se ubica dentro de la línea de investigación de Farmacovigilancia. La muestra seleccionada no probabilísticamente está conformada por 22 pacientes que presentan algún signo o síntoma por la ingesta de un medicamento, de los cuales 12 pertenecen a las áreas de Cirugía y Ortopedia de varones y 10 a las áreas de Cirugía y Ortopedia de mujeres. Se aplica el método inductivo, porque se verifican los datos de los pacientes mediante expedientes clínicos facilitados por el personal médico del Hospital Regional Santiago de Jinotepe, de los cuales se hacen observaciones, se registran los hechos y se analizan los resultados. Como resultados se obtuvo que de los 22 pacientes (100%) el mayor porcentaje con sospecha de RAM se encuentran entre las edades de 31-60 años, en mayor proporción el sexo masculino con 9 pacientes (40.91%), el grupo farmacológico que presentó un mayor porcentaje de sospecha de RAM son los antimicrobianos en 10 pacientes (45.45%), destacándose la Ceftriaxona 1 g IV. En relación al tratamiento aplicado por el personal médico para el manejo del paciente con sospecha de RAM al 45.45 % de los pacientes no se registra acción tomada por parte del personal médico, la imputabilidad de las reacciones adversas aplicando el Algoritmo de Karch-Lasagna modificado por Naranjo, da como resultado reacciones adversas medicamentosas probables 18.2 % y posibles 81.8 %. Según la severidad de las reacciones son más frecuentes las leves 72.7% y predomina la cefalea en 5 pacientes y mareos en 4 pacientes.

Improved wear performance of ultra high molecular weight polyethylene coated with hydrogenated diamond like carbon

Hydrogenated diamond like carbon (DLCH) thin films were deposited on medical grade ultra high molecular weight polyethylene (UHMWPE) by radio frequency plasma enhanced chemical vapor deposition. The DLCH coating thicknesses ranged from 250 to 700. nm. The substrates were disks made of UHMWPEs typically used for soft components in artificial joints, namely virgin GUR 1050 and highly crosslinked (gamma irradiated in air to 100. kGy) UHMWPEs. Mechanical and tribological properties under bovine serum lubrication at body temperature were assessed on coated and uncoated polyethylenes by means of nano-hardness and ball-on-disk tests, respectively. Morphological features of the worn surfaces were obtained by confocal microscopy and scanning electron microscopy. This study confirms an increase in surface hardness and good wear resistance for coated materials after 24. h of sliding test compared to uncoated polyethylene. These results point out that to coat UHMWPE with DLCH films could be a potential method to reduce backside wear in total hip and knee arthroplasties.Ministerio de Ciencia y Educación MAT2006-12603- C02-01, CSD2008-0002
