Lack of Answer Estimation by Fuzzy Control

The problem of the lack of answer in questions of survey is usually dealt with different estimation and classification procedures from the answers to other questions. In this document, the results of applying fuzzy control methods for the vote -one of the variables with bigger lack of answer in opinion polls- are presented

A Practical Case of Software Localization after System Development

Internationalization of software as a previous step for localization is usually taken into account during early phases of the life-cycle of software development. However, the need to adapt software applications into different languages and cultural settings can appear once the application is finished and even in the market. In these cases, software localization implies a high cost of time and resources. This paper shows a real case of a existent software application, designed and developed without taking into account future necessities of localization, whose architecture and source code were modified to include the possibility of straightforward adaptation into new languages. The use of standard languages and advanced programming languages has permitted the authors to adapt the software in a simple and straightforward mode

Bridging the Gap Between Human Language and Computer-Oriented Representations

Information can be expressed in many ways according to the different capacities of humans to perceive it. Current systems deals with multimedia, multiformat and multiplatform systems but another « multi » is still pending to guarantee global access to information, that is, multilinguality. Different languages imply different replications of the systems according to the language in question. No solutions appear to represent the bridge between the human representation (natural language) and a system-oriented representation. The United Nations University defined in 1997 a language to be the support of effective multilinguism in Internet. In this paper, we describe this language and its possible applications beyond multilingual services as the possible future standard for different language independent applications

Automatic Creation of Lexical Resources for an Interlingua-based System

The Universal Networking Language (UNL) is an interlingua designed to be the base of several natural language processing systems aiming to support multilinguality in internet. One of the main components of the language is the dictionary of Universal Words (UWs), which links the vocabularies of the different languages involved in the project. As any NLP system, coverage and accuracy in its lexical resources are crucial for the development of the system. In this paper, the authors describes how a large coverage UWs dictionary was automatically created, based on an existent and well known resource like the English WordNet. Other aspects like implementation details and the evaluation of the final UW set are also depicted

Effects training in hypoxia on cardiometabolic parameters in obese people: A systematic review of randomized controlled trial

The aim of the present review is to evaluate effects of intermittent hypoxia and exercise therapy in cardiometabolic parameters on adult obese people. Three well-known databases were selected: EMBASE, MEDLINE and Web of Science. Studies selection: Inclusion criteria were: (a) human healthy overweight or obese adults, (b) study randomized controlled trial, (c) original experimental study, (d) English languages and (e) therapy with intermittent hypoxia and exercise. The assessment of the methodological quality of each study was based upon the risk of bias (PEDro scale) and level of evidence (CBO Guidelines). five articles clearly met inclusion criteria and were reviewed to data extraction. In the hypoxia groups, weight, body mass index, waist circumference, waist-hip ratio, fat mass and lean mass improved in at least two studies in comparison with the baseline. Systolic blood pressure improved in one study. The lipid profile and the aerobic capacity were not reduced significantly. Results suggest that combined hypoxia with exercise may help to improve cardiometabolic parameters in obese people. [Abstract copyright: Copyright © 2018 The Authors.

Offensive performance under numerical inequality during exclusions in female handball

Los objetivos de este estudio fueron: 1) describir las situaciones de desigualdad numérica como consecuencia de exclusiones durante el torneo de balonmano femenino en los Juegos Panamericanos 2015; 2) analizar la eficacia para relacionarla con el resultado final de los partidos. Todos los partidos jugados por los equipos clasificados del puesto 1 al 4 en el torneo fueron analizados, utilizando la metodología observacional. Se construyó un instrumento ad hoc para realizar la observación. Un total de 14 partidos fueron analizados, en los cuales ocurrieron 461 acciones de desigualdad numérica. Las diferencias estadísticas entre las categorías analizadas fueron comprobadas usando el test de chi-cuadrado. Diferencia estadísticamente significativa fue considerada cuando p < 0.05. La mayor cantidad de acciones se concentró durante la segunda parte de los partidos (p < 0.05). Los resultados mostraron a los ganadores siendo más eficaces que los perdedores en la mayoría de las variables estudiadas (p < 0.05). Los equipos ganadores convierten el mayor porcentaje del total goles convertidos y mostraron un porcentaje menor de lanzamientos fuera. Los ganadores mostraron un mejor rendimiento en su eficacia de ataque (números de goles en relación al número de ataques/posesiones) cuando juegan en inferioridad. Se concluyó que los equipos ganadores convierten más goles que los perdedores en estas situaciones y que son más eficaces durante las acciones de desigualdad numérica.UY-MoUC

How Nanophotonic Label-Free Biosensors Can Contribute to Rapid and Massive Diagnostics of Respiratory Virus Infections : COVID-19 Case

Altres ajuts: Generalitat de Catalunya /CERCAThis ACS article is provided to You under the terms of this Standard ACS AuthorChoice License. License: https://pubs.acs.org/page/policy/authorchoice_termsofuse.htmlThe global sanitary crisis caused by the emergence of the respiratory virus SARS-CoV-2 and the COVID-19 outbreak has revealed the urgent need for rapid, accurate, and affordable diagnostic tests to broadly and massively monitor the population in order to properly manage and control the spread of the pandemic. Current diagnostic techniques essentially rely on polymerase chain reaction (PCR) tests, which provide the required sensitivity and specificity. However, its relatively long time-to-result, including sample transport to a specialized laboratory, delays massive detection. Rapid lateral flow tests (both antigen and serological tests) are a remarkable alternative for rapid point-of-care diagnostics, but they exhibit critical limitations as they do not always achieve the required sensitivity for reliable diagnostics and surveillance. Next-generation diagnostic tools capable of overcoming all the above limitations are in demand, and optical biosensors are an excellent option to surpass such critical issues. Label-free nanophotonic biosensors offer high sensitivity and operational robustness with an enormous potential for integration in compact autonomous devices to be delivered out-of-the-lab at the point-of-care (POC). Taking the current COVID-19 pandemic as a critical case scenario, we provide an overview of the diagnostic techniques for respiratory viruses and analyze how nanophotonic biosensors can contribute to improving such diagnostics. We review the ongoing published work using this biosensor technology for intact virus detection, nucleic acid detection or serological tests, and the key factors for bringing nanophotonic POC biosensors to accurate and effective COVID-19 diagnosis on the short term

Combination of Biomaterials and Extracellular Vesicles from Mesenchymal Stem-Cells: New Therapeutic Strategies for Skin-Wound Healing

Hard-to-heal chronic wounds associated with aging and high-prevalence pathologies, such as diabetes, are a global health problem. Therefore, it is necessary to advance effective treatments to accelerate wound healing. Among these potential treatments are new therapies based on mesenchymal stem cells (MSC) and their secretomes, including extracellular vesicles (EV). They have an important therapeutic potential for the treatment of chronic ulcers, due to their immunomodulatory activity, as well as their ability to induce angiogenesis, cell proliferation and cell migration. The use of MSC-derived EV in regenerative medicine involves cell-free therapies that decrease risks associated with cell therapies, such as the potential development of tumors. However, the short half-life of MSC-EV is a limitation for their clinical use. A therapeutic strategy to increase the regenerative efficiency of EV in wounds is to encapsulate them in biomaterials. The latter must protect and progressively release EV in damaged tissues, optimizing healing. Biomaterials that can be used include hydrogels. These, in addition to acting as a vehicle for sustained application of EV, can create favorable environments for wound healing. Thus, the aim of this review is to critically describe the latest advances in the development of such therapeutic strategies. It highlights the significance and clinical potential of these new therapies, as well as the need to develop clinical trials, to ascertain their performance

Two thirds of species in a global shark fin trade hub are threatened with extinction: Conservation potential of international trade regulations for coastal sharks

One third of chondrichthyan species (sharks, rays, and chimeras) are threatened with extinction, mainly due to unsustainable fishing. Large accessible international markets for meat and luxury products like dried fins can help drive overfishing by encouraging targeted capture or retention of high-value export species. If this is common, then species in international trade could have heightened extinction risk. Here, we examined the species composition of the Hong Kong shark fin market from 2014 to 2018, finding that traded species disproportionately occur in threatened categories (70.9%) and all premium value species are threatened. A small number of cosmopolitan species dominate the trade, but noncosmopolitan coastal species are still traded at concerning levels given their limited distribution. These coastal species are not generally subject to retention prohibitions, fisheries management, or international trade regulations and without management many could become extinct. The conservation potential of international trade regulations alone for coastal chondrichthyans depends on the extent to which overfishing is driven by export markets; socioeconomic studies of coastal fishing communities are needed to make this determination. Nonetheless, adding international trade regulations for more coastal shark species that are in the fin trade could prompt broad engagement with overfishing in nations lacking effective management
