(Churchill Livingstone, 2019)Background: Cardiovascular risk (CVR) biomarkers are of increasing interest because of their potential utility in management of cardiovascular diseases. The activity of the autonomic nervous system (ANS) is known to be ...
-
(IEEE, 2019)The modular multilevel converter (MMC) is a promising topology for high-power drive applications. However, large voltage fluctuations can be produced in the floating capacitors when the machine operates with high stator ...
-
(IEEE, 2019)This paper presents two capacitor voltage balancing (CVB) strategies for modular multilevel converter (MMC) applications. Both balancing schemes are based on model predictive control and are designed to efficiently solve ...
-
(Elsevier B.V., 2019)This study was about the simple method for the rapid colorimetric and visual detection of glucose molecules in water medium. Silver nanoparticles were spread on the chitosan surface (CS/Ag NCs) and it was characterized by ...
-
(Elsevier B.V., 2019)This contribution presents new high-pressure solubility data of solid trans-lutein in pure carbon dioxide (CO2), and mixtures of CO2 and ethanol. The cosolvent effect of ethanol was determined by comparing lutein solubility ...
-
(Elsevier B.V., 2019)We introduce a novel approach to simulate Gaussian random fields defined over spheres of ℝ3. Through continuation we embed the process on the sphere in a nonstationary random field of ℝ3 to use a turning bands method. We ...
-
(Academic Press Inc., 2019)In 2016 Astudillo, Diaz y Diaz and Friedman published sharp lower bounds for regulators of number fields of all signatures up to degree seven, except for fields of degree seven having five real places. We deal with this ...
-
(Academic Press, 2019)This work presents a comprehensive study of the uncertainties involved in the FrequencyResponse Function (FRF) of Piezoelectric Energy Harvesters (PEHs) based on experimentalresults. A proper experimental setup is designed ...
-
(American Institute of Mathematical Sciences, 2019)This paper is concerned with the qualitative properties of the solutions of mixed integro-differential equation (equation presented) with N ≥ 1, M ≥ 1 and ϵ 2 (0; 1). We study decay and symmetry properties of the solutions ...
-
(Elsevier B.V., 2019)Chile is the third largest exporter of kiwifruit in the world. Its varietal production has traditionally been focusedon green-fleshed kiwifruit varieties, with‘Hayward’being the most exported variety.‘Soreli’is a new ...
-
(Springer Netherlands, 2019)Drawing on de Sousa Santos’s work on Epistemologies of the South (2014), this paper critically examines the patterns of publication in higher education studies in mainstream and non-mainstream journals in Latin American ...
-
(Elsevier B.V., 2019)There is a consensus among language researchers that people can predict upcoming language. But do people always predict when comprehending language? Notions that “brains … are essentially prediction machines” certainly ...
-
(Elsevier Ltd, 2019)Flotation tests at laboratory scale describe the metallurgical behavior of the minerals that will be processed in the operational plant. This material is generally composed of ore and gangue minerals. These tests are usually ...
-
(Taylor and Francis Ltd., 2019)White clover (Trifolium repens L.) seed crops require insects for pollination. Apis mellifera Linnaeus, 1758 are normally placed within fields but other insects might also be contributing additional pollination. To ...
-
(Springer Verlag, 2018)Competency-based education in ergonomics was incorporated into the physical therapy undergraduate educational program in the University of Chile in 2009 in conjunction with the construction of the graduation profile. The ...
-
(Taylor and Francis Ltd., 2019)This work presents the preliminary results of the first field calibration campaign performed in the Atacama Desert, Chile, between the 18 and 22 August 2014, called the Atacama Field Campaign (ATAFIC 2014). In situ ...
-
(Springer-Verlag Wien, 2019)© 2018, Springer-Verlag GmbH Austria, part of Springer Nature. In this work, we numerically solve the Brinkman–Darcy equation coupled to the granular kinematic model using the finite elements method in 2D, to describe the ...
-
(Springer Verlag, 2019)This study aims to identify musculoskeletal health conditions present in a population that works in several different productive sectors in Chile in order to determine the physical risk factors in that type of labor and ...
-
(Springer Verlag, 2019)Objective The aim of the study was to analyze bone matrix (BMX) organization after bone grafting and repair using a new bioactive glass-ceramic (Biosilicate®) associated or not with particulate autogenous bone graft. Material ...
-
(Elsevier Inc., 2019)We study and compare three different mechanisms for capacity (slot) allocation in a congested airport when airlines have one-dimensional private information: direct allocation of slots, differentiated tolls and slot ...
