    Commutativity

    Full text link
    We describe a general framework for notions of commutativity based on enriched category theory. We extend Eilenberg and Kelly's tensor product for categories enriched over a symmetric monoidal base to a tensor product for categories enriched over a normal duoidal category; using this, we re-find notions such as the commutativity of a finitary algebraic theory or a strong monad, the commuting tensor product of two theories, and the Boardman-Vogt tensor product of symmetric operads.Comment: 48 pages; final journal versio

    According to American law, the results of all clinical trials must be published within twelve months. The situation is that 50% of all clinical trials are not published. This is a major problem because it is not possible to progress adequately towards the discovery and development of new therapies if there is no transparency in the results. Powell Smith and Goldcare have developed a new informatics tool, the Trials Tracker, which identifies automatically all concluded clinical trials, determines which of them have not been published and makes statistics. This tool allows disclosing the sponsors that hide their negative results

    ATVS-UAM NIST LRE 2009 System Description

    Full text link
    Official contribution of the National Institute of Standards and Technology; not subject to copyright in the United States.ATVS-UAM submits a fast, light and efficient single system. The use of a task-adapted nonspeech-recognition-based VAD (apart from NIST conversation labels) and gender-dependent total variability compensation technology allows our submitted system to obtain excellent development results with SRE08 data with exceptional computational efficiency. In order to test the VAD influence in the evaluation results, a contrastive equivalent system has been submitted exclusively changing ATVS VAD labels with BUT publicly contributed ones. In all contributed systems, two gender-independent calibrations have been trained with respectively telephone-only and mic (either mic-tel, tel-mic or mic-mic) data. The submitted systems have been designed for English speech in an application-independent way, all results being interpretable in the form of calibrated likelihood ratios to be properly evaluated with Cllr. Sample development results with English SRE08 data are 0.53% (male) and 1.11% (female) EER in tel-tel data (optimistic as all English speakers in SRE08 are included in total variability matrices), going up to 3.5% (tel-tel) to 5.1% EER (tel-mic) in pessimistic cross-validation experiments (25% of test speakers totally excluded from development data in each xval set). The submitted system is extremely light in computational resources, running 77 times faster than real time. Moreover, once VAD and feature extraction are performed (the heaviest components of our system), training and testing are performed respectively at 5300 and 2950 times faster than real time

J. Gonzalez-Dominguez, I. Lopez-Moreno, J. Franco-Pedroso, D. Ramos, D. T. Toledano, and J. Gonzalez-Rodriguez, "Multilevel and Session Variability Compensated Language Recognition: ATVS-UAM Systems at NIST LRE 2009" IEEE Journal of Selected Topics in Signal Processing, vol. 4, no. 6, pp. 1084 – 1093, December 2010This work presents the systems submitted by the ATVS Biometric Recognition Group to the 2009 Language Recognition Evaluation (LRE’09), organized by NIST. New challenges included in this LRE edition can be summarized by three main differences with respect to past evaluations. Firstly, the number of languages to be recognized expanded to 23 languages from 14 in 2007, and 7 in 2005. Secondly, the data variability has been increased by including telephone speech excerpts extracted from Voice of America (VOA) radio broadcasts through Internet in addition to Conversational Telephone Speech (CTS). The third difference was the volume of data, involving in this evaluation up to 2 terabytes of speech data for development, which is an order of magnitude greater than past evaluations. LRE’09 thus required participants to develop robust systems able not only to successfully face the session variability problem but also to do it with reasonable computational resources. ATVS participation consisted of state-of-the-art acoustic and high-level systems focussing on these issues. Furthermore, the problem of finding a proper combination and calibration of the information obtained at different levels of the speech signal was widely explored in this submission. In this work, two original contributions were developed. The first contribution was applying a session variability compensation scheme based on Factor Analysis (FA) within the statistics domain into a SVM-supervector (SVM-SV) approach. The second contribution was the employment of a novel backend based on anchor models in order to fuse individual systems prior to one-vs-all calibration via logistic regression. Results both in development and evaluation corpora show the robustness and excellent performance of the submitted systems, exemplified by our system ranked 2nd in the 30 second open-set condition, with remarkably scarce computational resources.This work has been supported by the Spanish Ministry of Education under project TEC2006-13170-C02-01.

    [ES] La ciberseguridad es un dominio vasto y complejo, por lo que las empresas están buscando activamente soluciones eficientes en este área. Los Knowledge Graphs (KG) son uno de los mecanismos que utilizan las organizaciones para explorar la seguridad entre activos y posibles ataques. Sin embargo, la gran cantidad de información puede generar una mala interpretación de los conceptos representados en estos modelos conceptuales. Como un Knowledge Graph puede considerarse una implementación de una conceptualización, la base de los conceptos es fundamental. De ahí, el apoyo de las mejores prácticas de Modelado Conceptual, especialmente de la rama de Ontologías. En este informe se lleva a cabo un estudio piloto para descubrir el estado del arte en ”Ontologías de Ciberseguridad”. A partir de este estudio, proponemos una encuesta para ampliar nuestro enfoque terminológico. La encuesta produjo una gran cantidad de datos, por lo que desarrollamos una API REST para la manipulación de datos y una base de datos NoSQL para almacenarlos, que es la principal contribución de este documento. Nuestro objetivo es proporcionar una herramienta de análisis ontológico para ayudar a las partes interesadas a evitar malas interpretaciones durante el desarrollo y la implementación de los KG.[EN] Cybersecurity is a vast and complex domain, therefore enterprises are actively seeking efficient solutions in this matter. Knowledge Graphs (KG) are one of the mechanisms that organizations use to explore the security among assets and possible attacks. However, the great amount of information can create misinterpretation of concepts represented in these structures of conceptualizations. As a KG may be considered an implementation of a conceptualization, the grounding of concepts is fundamental. Therefore, the support of Conceptual Modeling best-practices, especially regarding the branch of Ontologies. We made a pilot study that finds out the state-of-art in ”Cybersecurity Ontologies”. From this study, we propose a survey to extend our terminological approach. The survey produced a huge amount of data, thus we develop a REST API for data manipulation and a NoSQL database to store them which is the main contribution of this document. Our goal is to provide an ontological analysis tool to help stakeholders avoid misinterpretations during KGs development and implementation.This work has been developed under the project Digital Knowledge Graph – Adaptable Analytics API with the financial support of Accenture LTD.Franco Martins Souza, B.; Serrano Gil, LJ.; Reyes Román, JF.; Panach Navarrete, JI.; Pastor López, O.

    Historical note about intestinal inflammatory disease from a psychosomatic perspective; on occasion of some letters related to Juan Ramón Jiménez

    Get PDF
    On occasion of two letters written by Zenobia in 1949 and 1955 in which the gastrointestinal alterations of Juan Ramon Jimenez are commented and a clinical report of the Presbyterian Hospital of San Juan de Puerto Rico in 1950, some considerations are made about Intestinal inflammatory disease and its possible relation with psychological diseases. Intestinal inflammatory disease and psychological alteration in Juan Ramon Jimenez were parallel along all his life. His recurrent depressions, his marked neurotical character, his phobic and hypochondriac fears, together with his tendency towards isolation are a constant in his biography and without doubt influential in his intestinal pathology

    Trends and time variability in the northern continental shelf of the western Mediterranean

    Get PDF
    18 pages, 7 figures, 1 table, supporting information https://doi.org/10.1029/2004JC002799Different works appearing during the last decade show that the western Mediterranean has suffered a temperature and salinity increase during the 20th century. Most of these works analyze long-term trends in Levantine Intermediate Water (LIW) and Western Mediterranean Deep Water (WMDW); those dealing with changes in shallow and coastal waters are very scarce. It is still an open question whether these changes are due to meteorological factors occurring in the western Mediterranean or if they are caused by the salinity increase of the water masses contributing to deep water formation. In this work we analyze the data obtained in the last decade of the 20th century (and longer time series in some cases) within the frame of six projects aimed at the systematic collection of hydrographic data at fixed stations in the northern sector of the western Mediterranean (mainly in coastal areas). We detect strong warming trends in those stations located in the continental shelf (and probably with no influence of the LIW). This result could indicate that changes observed in the WMDW cannot be explained only on the basis of changes imported from the eastern basin. Another striking result is that these trends are an order of magnitude higher than those reported for the rest of the century, indicating that the 1990s have been an exceptionally warm decade. On the other hand, time series affected by the LIW show a salinity increase, and in some cases this is not accompanied by the corresponding temperature increment, indicating that the LIW salinity increase could also be a factor to be taken into account.

    Management of firearm facial fractures at the ‘‘Dr. José Eleuterio González’’: University Hospital Case Report

    Get PDF
    Gunshot wounds in the facial region produce important functional disabilities if they are not properly treated. They may also cause an important effect in the social and psychological development of the patient because of the aesthetic problems that they produce. This article presents a case of a 20 years-old female patient who was referred to our institution because of facial trauma secondary to a gunshot wound, whose treatment consisted of multiple reconstructive surgeries in order to obtain an adequate, functional and esthetic result. Also, we did a review of the bibliography in order to establish the proper management of the wounds found in these type of cases
