Enabling science with Gaia observations of naked-eye stars

ESA's Gaia space astrometry mission is performing an all-sky survey of stellar objects. At the beginning of the nominal mission in July 2014, an operation scheme was adopted that enabled Gaia to routinely acquire observations of all stars brighter than the original limit of G~6, i.e. the naked-eye stars. Here, we describe the current status and extent of those observations and their on-ground processing. We present an overview of the data products generated for G<6 stars and the potential scientific applications. Finally, we discuss how the Gaia survey could be enhanced by further exploiting the techniques we developed.Comment: 16 pages, 8 figures.

ÍNDICES PRODUCTIVOS EN OVEJAS SOMETIDAS A SUPLEMENTACIÓN ALIMENTARIA PREVIO AL PERIODO DE SERVICIO

El trabajo de investigación se realizó en el departamento de Caaguazú (Py), con el objetivo de determinar el efecto de la suplementación previa al servicio, sobre la ganancia de peso, índice de parición e incidencia en partos múltiples, en ovejas adultas alimentadas sobre pradera nativa. El periodo experimental fue de 216 días. El diseño experimental utilizado fue el completamente al azar, con 2 tratamientos y 10 repeticiones, cada animal fue considerado una unidad experimental. Los tratamientos fueron: T1,  ovejas sin suplementación previo al servicio; y T2: ovejas con suplementación previa al servicio (flushing), estas últimas tuvieron un periodo de acostumbramiento gradual de 12 días hasta llegar a 1,5% del peso vivo de un balanceado comercial. Las variables evaluadas fueron: los pesos vivos de las ovejas, el porcentaje de pariciones, el tipo ya sea simple o múltiple y los pesos de los corderos al nacimiento. Durante el periodo del Flushing se observaron diferencias significativas para las ganancias diarias de pesos entre los dos tratamientos, donde el T2 fue superior (128 g/d vs -29 g/d). Las ganancias de pesos totales no presentaron diferencias significativas. En ambos tratamientos se obtuvo el 100% de pariciones y no fueron registrados partos múltiples. Los pesos al momento de nacimiento promedios en ambos tratamientos, sin considerar el sexo, fueron de 3,51Kg (± 1,41) para el T2 y 3,47 Kg (± 1,81) para el T1, los cuales no presentaron diferencias estadísticas  significativas entre sí

Leading nucleon and inelasticity in hadron-nucleus interactions

We present in this paper a calculation of the average proton-nucleus ine- lasticity. Using an Iterative Leading Particle Model and the Glauber model, we relate the leading particle distribution in nucleon-nucleus interactions with the respective one in nucleon-proton collisions. To describe the leading particle distribution in nucleon-proton collisions, we use the Regge-Mueller formalism. To appear in Journal of Physics G.Comment: 11 pages, 2 figure

The Strongyloides stercoralis-hookworms association as a path to the estimation of the global burden of strongyloidiasis: A systematic review

Soil-transmitted helminths (STH) represent a significant public health problem. However, Strongyloides stercoralis is not yet integrated into the control strategy against STH, given limi- tations to accurately assess its burden. Considering that S. stercoralis shares biological and epidemiological characteristics with hookworms, we describe a new approach for an improved estimation of the burden of infections by S. stercoralis based on the prevalence and burden of hookworms and the relationship between these species. A systematic review of publications reporting prevalence rates for S. stercoralis and hookworms was carried out. The data was classified into two categories: 1) “Community”, with surveys including all age groups, and 2) “SAC”, with surveys limited to school-aged children. The relationship between S. stercoralis and hookworms was characterized in order to estimate the global burden of S. stercoralis infections. The study is registered in PROSPERO (CRD42019131127). Spearman correlation coefficient between S. stercoralis and hookworms was estimated and the global burden of S. stercoralis infections was estimated using a regression model. A total of 119 articles were included, and a significant positive correlation between the burden of S. stercoralis and hook- worms was identified. Spearman’s coefficient for Community surveys was 0.94 and for SAC surveys it was 0.63. Based on the linear model, the global burden of S. stercoralis infections was estimated at 386 million (95%CI 324–449 million) people, including 22 million (95%CI 20–24 million) SAC. The significant relationship between S. stercoralis and hookworms allows an estimation of the global burden of S. stercoralis infections in most epidemiologic settings using hookworm burden and justifies the search of integrated control activities
