(Optical Soc Amer, 2020)We investigate the interplay between two fundamentally different localization mechanisms in discrete systems: dynamic localization, i.e., resonant wave packet revivals in periodically driven lattices, and Anderson localization, ...
-
(IOP Publishing, 2020)In Meidt et al., we showed that gas kinematics on the scale of individual molecular clouds are not entirely dominated by self-gravity but also track a component that originates with orbital motion in the potential of the ...
-
(American Physical Society, 2020)Unraveling bacterial strategies for spatial exploration is crucial for understanding the complexity in the organization of life. Bacterial motility determines the spatiotemporal structure of microbial and controls infection ...
-
(Oxford Unv Press, 2020)We report the discovery of the 1.008-d, ultrashort period (USP) super-EarthHD213885b (TOI141b) orbiting the bright (V= 7.9) star HD 213885 (TOI-141, TIC 403224672), detected using photometry from the recently launched TESS ...

USco1621 B and USco1556 B: two wide companions at the deuterium-burning mass limit in Upper Scorpius (EDP Sciences, 2020)Aims. Our objective is to identify analogues of gas giant planets, but located as companions at wide separations of very young stars. The main purpose is to characterise the binarity frequency and the properties of these ...
-
(IOP Publishing, 2020)It is shown that the interplay between curvature and interfacial Dzyalonshinsky-Moriya interaction (DMI) is a pathway to ultrafast domain wall (DW) dynamics in ferromagnetic nanotubes. In this work, we theoretically study ...
-
(Taylor & Francis, 2020)In this study, we aimed to describe a modern, efficient, and reproducible methodology to optimize respiration rate parameters coupled with transport properties in mass balances describing Modified atmosphere packaging (MAP) ...
-
(Elsevier, 2020)The design of conservation management plans is a crucial task for ensuring the preservation of ecosys- tems. A conservation plan is typically embodied by two types of decisions: in which areas of a given territory it will ...

Chondroinductive Alginate-Based Hydrogels Having Graphene Oxide for 3D Printed Scaffold Fabrication (American Chemical Society, 2020)Scaffolds based on bioconjugated hydrogels are attractive for tissue engineering because they can partly mimic human tissue characteristics. For example, they can further increase their bioactivity with cells. However, ...
-
(MDPI, 2020)Multi-sensor systems are proliferating in the asset management industry. Industry 4.0, combined with the Internet of Things (IoT), has ushered in the requirements of prognostics and health management systems to predict the ...
-
(Universidad de Chile, 2019)Para una empresa es vital el poder predecir situaciones de riesgo, y anteponerse a ellas. Por lo general, dichas situaciones de peligro pueden producir grandes costos económicos. Tal es el caso de la industria minera, ...
-
(Universidad de Chile, 2019)El presente documento es realizado en la empresa Colbún S.A. (generadora y distribuidora de energía eléctrica), bajo la Gerencia de TI. El caso de estudio nace a partir de una serie de eventos del mercado eléctrico tanto ...
-
(Elsevier, 2020)Usually in block and panel caving mines, when the caving connects to the surface, monitoring of vertical stresses over production drifts is minimal due to the low probability of seismic events. However, when the stresses ...
-
(Taylor & Francis, 2020)In this paper, we present an automatic method, without human supervision, for the detection and classification of blue whale vocalizations from passive acoustic monitoring (PAM) data using Hidden Markov Model technology ...
-
(Universidad de Chile, 2019)La introducción de herramientas de Machine Learning para resolver problemas de Big Data, han creado diversas oportunidades, en particular en la industrial del retail. Esta tesis está dividida en dos ensayos donde se usan ...
-
(Universidad de Chile, 2019)El presente estudio se centra en la elaboración de un modelo de madurez para las iniciativas de datos abiertos de las instituciones del Gobierno de Chile. Este modelo identifica “Dimensiones”, “Variables” y “Niveles de ...
-
The economics of automated public transport: Effects on operator cost, travel time, fare and subsidy (Elsevier, 2020)It is currently unknown in which city environments, automated vehicles could be deployed at reasonable speeds, given safety concerns. We analytically and numerically assess the impact of automation for optimal vehicle size, ...
-
(Elsevier, 2020)Previous real-time crash prediction models have scarcely used data disaggregated by vehicle type such as light, heavy and motorcycles. Thus, little effort has been made to quantify the impact of flow composition variables ...
-
(Elsevier, 2020)The evaluation of the depth of brittle failure around excavations is of major importance in order to optimize the design of underground excavations and ensure the safety of workers and equipment. The current proposed ...
-
(Springer, 2020)The Atacama Desert is one of the oldest and driest places on Earth. In the last decade, microbial richness and diversity has been acknowledged as an important biological resource of this region. Owing to the value of the ...
