(Copernicus Gesellschaft, 2020)In wintertime, high concentrations of atmospheric fine particulate matter (PM2.5) are commonly observed in the metropolitan area of Santiago, Chile. Hourly peaks can be very strong, up to 10 times above average levels, but ...
-
(Elsevier, 2020)Ferritin is a globular hollow protein that acts as the major iron storage protein across living organisms. The 8 nmdiameter internal cavity of ferritin has been used as a nanoreactor for the synthesis of various metallic ...
-
(IOP Publishing, 2020)We study the imprints of an effective dark energy fluid in the large scale structure of the universe through the observed angular power spectrum of galaxies in the relativistic regime. We adopt the phenomenological approach ...
-
(Wiley, 2020)The study demonstrates the performance of heating efficiency in single-phase and binary phase spinel ferrite nanosystems. Ferrimagnetic cobalt ferrite (CoFe2O4) (CFO) and superparamagnetic copper ferrite/copper oxide ...
-
(Universidad de Chile, 2020)La principal información para el diseño de caserones consiste en determinar la estabilidad de la excavación con el fin de cuantificar la dilución planificada y estimar el potencial de dilución asociada a la sobre excavación ...
-
(Universidad de Chile, 2020)The model updating of the electro-mechanical properties of Piezoelectric Energy Harvesters (PEHs) using experimental data within a Bayesian inference setting is discussed. The implementation requires: a predictive model ...
-
(Universidad de Chile, 2020)El macizo de La Cabaña se encuentra en la provincia de Cautín, en la región de la Araucanía y es el afloramiento de peridotitas de mayor tamaño en Chile, con cromititas podiformes con presencia de EGP. Las rocas de La ...
-
(Universidad de Chile, 2020)En un mercado global crecientemente más competitivo, bajar los costos operacionales y asegurar la estabilidad operacional ha saltado directamente como prioridad en las decisiones estratégicas de administración relacionadas ...
-
(Universidad de Chile, 2019)Los incendios son un problema mundial que genera gran dificultad en la planificación forestal. Para abordarlo han surgido enfoques como el Fire Smart Forest Management, que busca incorporar medidas de prevención de incendios ...
-
(Springer, 2020)The sum of squares (SoS) hierarchy gives an automatized technique to create a family of increasingly tight convex relaxations for binary programs. There are several problems for which a constant number of rounds of this ...
-
(Institution of Engineering and Technology, 2020)In this study, a methodology to develop hourly demand scenarios in a medium-term horizon for primary distribution substations is presented and applied to a case study. The main contribution of this study is that it addresses ...
-
(Springer, 2020)We acknowledge the priority on the introduction of the formula of t-lgHill estimator for the positive extreme value index. We provide a novel motivation for this estimator based on ecologically driven dynamical systems. ...
-
(Springer, 2020)Extending a result of Rado to hypergraphs, we prove that for all s,k,t is an element of N$$s, k, t \in {\mathbb {N}}$$\end{document} with k >= t >= 2 the vertices of every r=s(k-t+1)-edge-coloured countably infinite complete ...
-
(Springer, 2020)We give new criteria for weak and strong invariant closed sets for differential inclusions in Double-struck capital Rn, and which are simultaneously governed by Lipschitz Cusco mapping and by maximal monotone operators. ...
-
(Elsevier, 2020)The size of manufactured parts is naturally bound by the size of their production machines. In this paper, we explore the alternative of making a machine that can continuously navigate along an object being fabricated, ...
-
(Optical Society of Japan, 2020)It is well known that the performance of orthogonal frequency division multiplexing (OFDM) is limited by phase noise, which depends on the laser linewidths for coherent-detection radio over fiber (RoF) systems. In this ...
-
(American Geophysical Union, 2020)Changes in climate are usually considered in terms of trends or differences over time. However, for many impacts requiring adaptation, it is the amplitude of the change relative to the local amplitude of climate variability ...
-
(IOP Publishing, 2020)Cosmic inflation may have led to non-Gaussian initial conditions that cannot be fully parametrised by 3- and/or 4-point functions. In this work, we discuss various strategies to search for primordial non-Gaussianity beyond ...
-
(Nature, 2020)Megathrust earthquakes are responsible for some of the most devastating natural disasters(1). To better understand the physical mechanisms of earthquake generation, subduction zones worldwide are continuously monitored ...
-
(IOP Publishing, 2020)We present a measurement of the gravitational lensing deflection power spectrum reconstructed with two seasons of cosmic microwave background polarization data from the Polarbear experiment. Observations were taken at 150 ...
