¿Qué determina la realización de la prueba de VIH en la población panameña sexualmente activa entre los 15-59 años de edad? Hallazgos del análisis secundario de ENASSER 2009.
Authors: Jenkins Lorna 
Published: March 2020

En Panamá sólo el 36.3% de los diagnósticos se hacen en la fase de VIH. Es necesario conocer los factores que se asocian a la realización de la prueba de VIH en personas con vida sexual activa en Panamá para diseñar estrategias para la detección temprana de las personas que viven con VIH. El presente estudio es un análisis secundario a partir de la Encuesta Nacional de Salud Sexual y Reproductiva 2009. Se analizaron las respuestas de 7,359 casos que reportaron tener vida sexual activa. Los análisis se realizaron con el programa de análisis estadístico Stata SE 13.0. El 13.8% de los hombres y 18.4% de las mujeres se realizaron la prueba de VIH en los doce meses previos a la encuesta. Uno de cada diez lo hizo de manera voluntaria. Factores como pertenecer a un grupo indígena, o residir en un área comarcal se asoció de manera estadísticamente significativa a la no realización de la prueba tanto en hombres como en mujeres. Factores como el número de parejas sexuales en los últimos 12 meses, uso de condón y conocimientos comprehensivos de VIH no mostraron asociación estadísticamente significativa ni en hombres ni en mujeres. Consideramos urgente diseñar estrategias para au-mentar el flujo de las personas que asisten a los servicios de asesoría y tamizaje de VIH, especialmente en las áreas indígenas y a la población auto-identificada como indígena.
AbstractOnly 36.3% of HIV/AIDS diagnoses in Panama are made at an early stage. Thus, it is relevant to describe the factors that are associated with conducting HIV testing in sexually active individuals in Panama to design strategies for early detection of people living with HIV. This is a secondary analysis from the Sexual and Reproductive Health National Survey conducted in 2009. There were 7,359 cases identified to conduct further analysis, which were performed using the statistical analysis software Stata SE 13.0. Only 13.8% of men and 18.4% of women were tested for HIV in the twelve months preceding the survey. One in ten did it so voluntarily. Factors such as belonging to an indigenous group, or residing in an indigenous area are statistically associated to not performing the HIV test in men and women. Factors such as the number of sexual partners in the last 12 months, condom use and comprehensive knowledge of HIV are not statistically significant in either men or women. It is urgent to design strategies in order to increase the flow of people attending counseling services and HIV screening, especially in indigenous areas and in population self-identified as indigenous, as well as to increase knowledge and sexual risk behaviors associated to HIV.

Los nuevos medios sociales comprenden una nueva esfera mediática donde se generan nuevos formatos informativos. En este sentido, nuestra investigación se enfocará en una nueva dinámica de noticia de la comunidad en los nuevos medios; para ello, empleará el método hermenéutico para, a través de este, hacer un análisis semiótico del espacio proyectado por KolectiVOZ, “Culopropismo”, que lo encontramos en la plataforma de Facebook. El medio digital denuncia través de su espacio quejas de la ciudadanía como invasión o apropiación indebida del espacio público. De esta manera, el análisis semiótico partirá de las dimensiones respectivas: sintáctica, semántica y pragmática, que se conectará con los resultados de las hipermediaciones técnicas y sociales que permiten la comunicación en el espacio digital, y qué tipo de audiencias son las que consumen dichos contenidos. En la actualidad, vivimos la sociedad red (Castells, 2001) y con el desarrollo de las nuevas tecnologías se evidencia un bombardeo de información debido la actividad continua de los prosumidores (Scolari, 2008) que se trata de una audiencia que no solo consume contenidos, sino que además los produce. Ante ello, las audiencias cohabitan en una ecología de medios donde conviven los medios digitales y los medios analógicos (Scolari, 2015), en consecuencia, los formatos de los contenidos noticiosos se diversificaron, no solo en cuanto a contenido sino también en formatos (Oviedo & Ulloa, 2016). Ante ello, la internet por ser una gran plataforma de información supera con creces las dimensiones informativas que los medios analógicos pueden brindar, en los cuales se presentan todo tipo de situaciones que favorecen o no a una sociedad. Los nativos digitales (Piscitelli, 2008) que nacieron rodeados de tecnología tienen una serie de capacidades cognitivas que no tienen los migrantes digitales, es por ello, que los nuevos formatos de las noticias están enfocados en esta nueva audiencia.

Effect of Sampling Rate Reduction and Signal Filtering for Gunfire Sound Classification with Spectral Vector using ANN
Authors: Tangkawanit Settha , Kanprachar Surachet 
Published: March 2020

To identify the type of the shooting gun, there are many important parameters to be considered. One key feature is the gunfire sound. It has been shown [1, 2] that applying the Artificial Neural Network or ANN to the gunfire sound database, the gunfire sound classification can be obtained. The input data to the ANN model was the frequency components in the frequency range at which occupying by the gunfire sound. It is seen that if the number of input frequency components is large, a significant computational resource is required. To reduce such resource so that the whole classification process can be done in a small device; for example, in a mobile phone, the sampling frequency is considered. In this research, the sampling frequency for transforming the input gunfire sound into a digital signal is varied from 44.1 kHz down to 4.41 kHz, so that the effect of the sampling frequency on the gunfire sound classification can be studied. 6 different types of gunfire sound are considered. In order to determine the effectiveness of the classification process, noise is also added to the gunfire sound samples; thus, different values of signal-to-noise ratio are considered. Additionally, the effect of applying different types of signal filtering on the gunfire sound classification is taken into account. It is found that only reducing the sampling frequency on the input gunfire sound signal does not deliver a good performance in terms of gunfire sound classification. To obtained a good classification accuracy. signal filtering has to also be applied to the process. With Chebyshev Type II filter and 4.41 kHz sampling frequency, the obtained classification accuracy is all 100% for the practical range of SNR; that is, between 20 dB down to 5 dB. This impressive classification accuracy comes with a huge reduction on the computational resource; that is, 10 times reduction; since the sampling frequency is reduced from 44.1 kHz to 4.41 kHz. The findings from this work can be certainly applied to the gunfire sound classification system with limited computational resource in order to obtain high classification accuracy.

Published: March 2020

Abstract
Probabilistic cataloging (PCAT) outperforms traditional cataloging methods on single-band optical data in crowded fields. We extend our work to multiple bands, achieving greater sensitivity (∼0.4 mag) and greater speed (500×) compared to previous single-band results. We demonstrate the effectiveness of multiband PCAT on mock data, in terms of both recovering accurate posteriors in the catalog space and directly deblending sources. When applied to Sloan Digital Sky Survey (SDSS) observations of M2, taking Hubble Space Telescope data as truth, our joint fit on r- and i-band data goes ∼0.4 mag deeper than single-band probabilistic cataloging and has a false discovery rate less than 20% for F606W ≤ 20. Compared to DAOPHOT, the two-band SDSS catalog fit goes nearly 1.5 mag deeper using the same data and maintains a lower false discovery rate down to F606W ∼ 20.5. Given recent improvements in computational speed, multiband PCAT shows promise in application to large-scale surveys and is a plausible framework for joint analysis of multi-instrument observational data. https://github.com/RichardFeder/multiband_pcat.

Abstract
We develop an axisymmetric numerical MHD model that allows us to investigate the spatial characteristics of the interplanetary magnetic field (IMF) and key solar wind plasma parameters from 20 to 400 solar radii over all heliolatitudes. The study is aimed at an analysis of the evolution of the spatial structure of the heliosphere through the solar cycle. We consider various combinations of the relative input of the quadrupole and dipole harmonics of the solar magnetic field to imitate the solar cycle. Self-consistent solutions for the IMF, electric current, solar wind speed, density, thermal pressure, and temperature in the solar wind are obtained. The spatial evolution of the IMF and properties of quasi-stationary current sheets (QCSs) are analyzed during different phases of the solar cycle. It is shown that a classic low-latitude heliospheric current sheet is formed in the solar wind as a part of the system of longitudinal and latitudinal electric currents symmetric in the northern and southern hemispheres only during solar minimum. While the quadrupole magnetic field increases, the second QCS appears. The model successfully describes a smooth transition from the state of the fast solar wind at high heliolatitudes and the slow solar wind at low heliolatitudes at solar minimum to the solar wind speed of the same values in a wide range of heliolatitudes at solar maximum. It reproduces the actively debated phenomenon of the south–north asymmetry of the IMF in the heliosphere and shows the distribution of thermal plasma parameters consistent with observations.

Abstract
Solar eruptions are the most powerful drivers of space weather. To understand their cause and nature, it is crucial to know how the coronal magnetic field evolves before eruption. Here we study the formation process of a relatively large-scale magnetic flux rope (MFR) in active region NOAA 12371 that erupts with a major flare and coronal mass ejection on 2015 June 21. A data-driven numerical magnetohydrodynamic model is employed to simulate three-dimensional coronal magnetic field evolution of 1 day duration before the eruption. Comparison between the observed features and our modeled magnetic field discloses how the pre-eruption MFR forms. Initially, the magnetic field lines were weakly twisted as being simple sheared arcades. Then a long MFR was formed along the polarity inversion line due to the complex photospheric motion, which is mainly shearing rather than twisting. The presence of the MFR is evidenced by a coherent set of magnetic field lines with twist number above unity. Below the MFR a current sheet is shown in the model, suggesting that tether-cutting reconnection plays a key role in the MFR formation. The MFR’s flux grows as more and more field lines are twisted due to continuous injection of magnetic helicity by the photospheric motions. Meanwhile, the height of the MFR’s axis increases monotonely from its formation. By an analysis of the decay index of its overlying field, we suggest that this is because the MFR runs into the torus instability regime and becomes unstable, which finally triggers the eruption.

Abstract
The nature of Milky Way dwarf spheroidals (MW dSphs) has been questioned, in particular whether they are dominated by dark matter (DM). Here we investigate an alternative scenario, for which tidal shocks are exerted by the MW to DM-free dSphs after a first infall of their gas-rich progenitors, and for which theoretical calculations have been verified by pure N-body simulations. Whether or not the dSphs are on their first infall cannot be resolved on the sole basis of their star formation history. In fact, gas removal may cause complex gravitational instabilities, and near-pericenter passages can give rise to tidal disruptive processes. Advanced precision with the Gaia satellite in determining both their past orbital motions and the MW velocity curve is, however, providing crucial results. First, tidal shocks explain why DM-free dSphs are found preferentially near their pericenter, where they are in a destructive process, while their chance to be long-lived satellites is associated with a very low probability P ∼ 2 × 10−7, which is at odds with the current DM-dominated dSph scenario. Second, most dSph binding energies are consistent with a first infall. Third, the MW tidal shocks that predict the observed dSph velocity dispersions are themselves predicted in amplitude by the most accurate MW velocity curve. Fourth, tidal shocks accurately predict the forces or accelerations exerted at half-light radii of dSphs, including the MW and the Magellanic System gravitational attractions. The above is suggestive of dSphs that are DM-free and tidally shocked near their pericenters, which may provoke a significant quake in our understanding of near-field cosmology.

Introduction: Preeclampsia remains one of the most common causes of maternal and perinatal mortality worldwide. A significant role in the pathogenesis of this pathology is assigned to placental ischemia and endothelial dysfunction. Therefore, the aim of the present study was to study the effectiveness of asialized erythropoietin and arginase II selec­tive inhibitors: KUD-259 and KUD-974 in the correction of morphofunctional disorders of the cardiovascular system in experimental preeclampsia.
Materials and methods: The study was performed in 260 female Wistar rats, each weighing 250–300 g. An AD­MA-like preeclampsia was reproduced in the experiment. To assess the emerging morphofunctional disorders, the fol­lowing parameters were used: blood pressure, coefficient of endothelial dysfunction, microcirculation in the placenta, proteinuria, fluid content in the omentum, concentration of terminal metabolites in the blood plasma, and morphometric parameters of fetuses.
Results and discussion: The administration of arginase II selective inhibitor KUD-974 in combination with asialized erythropoietin leads to a pronounced correction of emerging changes: a decrease in systolic and diastolic blood pres­sure in 1.5 and 1.7 times, a decrease in proteinuria in 3.6 times and a decrease in fluid content in the omentum. When arginase II selective inhibitor KUD 974 and asialized erythropoietin are used with methyldopa, the positive effects of the former are enhanced.
Conclusion: Arginase II selective inhibitors KUD-259 and KUD-974 and asialized erythropoietin have a pronounced positive effect on the correction of morphofunctional disorders in animals with ADMA-like preeclampsia.

Published: March 2020

Les causes de rupture du maintien au domicile de personnes en fin de vie sont souvent liées à l’épuisement des proches et au sentiment d’insécurité. L’objectif de cette étude est de connaître les attentes envers le médecin généraliste (MG) de l’aidant principal d’une personne en phase palliative avancée au domicile. Il s’agit d’une étude qualitative sur la base de dix entretiens semi-directifs menés avec un guide d’entretien auprès de proches de personnes décédées. Les enregistrements ont fait l’objet d’une analyse de contenu. Les principales attentes envers le MG concernent sur le plan technique, un ajustement des thérapeutiques ; sur le plan organisationnel, une disponibilité importante ainsi qu’un lien entretenu avec les différents intervenants et les structures notamment de soins palliatifs ; sur le plan relationnel, une écoute et une information sur l’évolution de la maladie ; sur le plan décisionnel, le respect de la volonté du patient. Les résultats sont discutés à partir de trois concepts adaptés au MG, à savoir la capacité d’adaptation de sa pratique et de son savoir-être, l’anticipation des situations d’urgence et de l’évolution de la maladie, et enfin l’assurance d’une continuité des soins qui passe notamment par leur permanence et leur coordination. Les moyens dont dispose le MG paraissent insuffisants pour assurer le maintien à domicile devant la charge que représente un patient en phase palliative avancée. La diffusion de la démarche palliative au domicile et l’optimisation de l’interprofessionnalité auprès des personnes en fin de vie au domicile et de leurs proches sont à développer. L’enjeu est le respect de la demande du patient de mourir à son domicile.

Published: March 2020

Il existe tant de manières de « faire symbole » pour une TI qu’il est compliqué pour un manager d’en comprendre et d’en maîtriser toutes les dimensions. Comment prendre en compte cette dimension symbolique lors de leur déploiement ? À partir de la littérature, nous distinguons tout d’abord trois significations symboliques types associées à la TI : la TI comme Solution ; la TI comme Utopie ; et la TI comme Menace. Ensuite, nous proposons une description détaillée de ces trois significations symboliques, et les associons à des stratégies de déploiement. Cela permet enfin de proposer une grille descriptive, mobilisable par les managers, pour gérer la dimension symbolique lors du déploiement d’une TI.

Atrial fibrillation (AF) is a common type of cardiac arrhythmia. AF is associated with increased rates of death and hospitalizations. It is also related to a degraded quality of life and reduced exercise capacity. Ageing increases the risk of developing AF, as well as hypertension and obesity. Continuous ECG monitoring is required in patients with previously diagnosed AF. Studies have also demonstrated that daily ECG monitoring increases the successful detection of silent AF among older adults. In this sense facilitating AF monitoring using portable devices such as Smartphones will increase patients life quality and could help to an early diagnosis. With this in mind in this work we present a proposal to detect AF using pulsatile photoplethysmogram (PPG) signal from a fingertip using the built-in camera lens in a smartphone. We developed an algorithm intended to sense paroxysmal AF considering resource utilization capabilities in order to be used in mobile devices with constrained.
