(BMC, 2020)BackgroundBerry size is considered as one of the main selection criteria in table grapes breeding programs, due to the consumer preferences. However, berry size is a complex quantitive trait under polygenic control, and ...
-
(Oxford University Press, 2020)We present new Atacama Large Millimeter/submillimeter Array observations of the tadpole, a small globule in the Carina Nebula that hosts the HH 900 jet+outflow system. Our data include (CO)-C-12, (CO)-C-13, (CO)-O-18 J=2-1, ...
-
(Universidad de Chile, 2020)Los modelos de aprendizaje supervisado han logrado resolver problemas con gran precisión en varias ámbitos como la medicina, el transporte y el financiero. Sin embargo, la mayoría de estos métodos se comportan como cajas ...
-
(Universidad de Chile, 2020)Inmobiliaria Activa, es una empresa que ha dedicado su trayectoria a la venta y arriendo de departamentos en Santiago de Chile. El objetivo principal de este trabajo de título es el de diseñar una estrategia de implementación ...
-
(Universidad de Chile, 2020)En la siguiente memoria, se aborda un problema de predicción de demanda de productos en la industria supermercadista usando avances metodológicos recientes. Esto es debido a que los modelos y metodologías utilizadas más ...
-
(Universidad de Chile, 2020)El Lago Villarrica es un cuerpo de agua con origen glacial que se encuentra en la zona precordillerana de la región de La Araucanía. Debido a la cercanía de centros urbanos, adquieren relevancia las actividades antrópicas ...
-
(Universidad de Chile, 2020)La desalinización de agua de mar mediante osmosis reversa (RO) es un proceso que ha destacado en los últimos años debido a su alta eficiencia. Dentro de los fenómenos que afecta en mayor medida a este proceso se encuentra ...
-
(Universidad de Chile, 2020)El presente trabajo de Título se enmarca en el contexto de la seguridad contra incendios en construcciones de madera. En particular, se enfoca al diseño resistente al fuego de elementos constructivos que cumplen una función ...
-
Estabilidad para modelo de Light Sheet Fluorescence Microscopy 2D y extensión al caso tridimensional (Universidad de Chile, 2020)La observación a escala celular de procesos biológicos de forma continua en el tiempo y en las tres dimensiones espaciales es uno de los grandes objetivos en la investigación científica para comprender aspectos esenciales ...
-
(IOP, 2020)While protoplanetary disks often appear to be compact and well organized in millimeter continuum emission, CO spectral line observations are increasingly revealing complex behavior at large distances from the host star. ...
-
(EDP Science, 2020)We report the confirmation and mass determination of three hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HIP 65Ab (TOI-129, TIC-201248411) is an ultra-short-period Jupiter orbiting a ...
-
(Routledge, 2020)Clinicians and researchers have become increasingly interested in the potential of technology in assisting persons with dementia (PwD). However, several issues have emerged in relation to how studies have conceptualized ...
-
(Elsevier, 2020)We present the first solution to finding tau-majorities on tree paths. Given a tree of nnodes, each with a label from [1..sigma], and a fixed threshold 0 < tau 1, such a query gives two nodes u nd v nd asks for all the ...
-
(American Physical Society (APS), 2020)We report on a study of a one-dimensional linear photonic lattice hosting, simultaneously, fundamental and dipolar modes at every site. We show how, thanks to the coupling between different orbital modes, this minimal model ...
-
(Springer, 2020)The role and relevance of speech synthesis and speech recognition in social robotics is addressed in this paper. To increase the generality of this study, the interaction of a human being with one and two robots when ...
-
(MDPI, 2020)Production planning decisions in the mining industry are affected by geological, geometallurgical, economic and operational information. However, the traditional approach to address this problem often relies on simplified ...
-
(Springer, 2020)Mining activities are among the main sources of potentially toxic elements (PTEs) in the environment which constitute a real concern worldwide, especially in developing countries. These activities have been carried out for ...
-
(Nature, 2020)In this work, we study the phenomena of Rogue waves (RW) on one-dimensional (1D) photonic lattices presenting diagonal and non-diagonal disorder. Our results show the appearance of extreme events coming from the superposition ...
-
((IEEE) Institute of Electrical and Electronics Engineers, 2020)In this letter, we propose a robust approach to train map-less navigation policies that rely on variable size 2D point clouds, using Deep Reinforcement Learning (Deep RL). The navigation policies are trained in simulations ...
-
(MDPI, 2020)Brittle failure mechanisms can affect the seismic performance of structures composed of intersecting moment resisting frames, if the biaxial effects are not considered. In this research, the bidirectional cyclic response ...
