Spatial distribution and interannual variability of coastal fog and low clouds cover in the hyperarid Atacama Desert and implications for past and present Tillandsia landbeckii ecosystems
(SPRINGER WIEN, 2021-10)The hyperarid Atacama Desert coast receives scarce moisture inputs mainly from the Pacific Ocean in the form of marine advective fog. The collected moisture supports highly specialized ecosystems, where the bromeliad ... -
Spatial inequality and aspirations for economic inclusion among Latin American youth
(Elsevier, 2020-11)Youths' aspirations formation is typically analysed in its association with individual, family and school characteristics. This paper adopts a wider perspective and uses descriptive and econometric analysis to investigate ... -
Spatio-temporal variation of the strain field in the southern Central Andes broken-foreland (27 degrees 30 ' S) during the Late Cenozoic
(Elsevier BV, 2021-03)We present an integrated structural and Anisotropy of Magnetic Susceptibility (AMS) study focused on the characterization of the spatio-temporal variation of the strain field during the main Neogene deformation, of the ... -
Spatio-Temporal Variation of the Urban Heat Island in Santiago, Chile during Summers 2005-2017
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)Urban heat islands (UHIs) can present significant risks to human health. Santiago, Chile has around 7 million residents, concentrated in an average density of 480 people/km(2). During the last few summer seasons, the highest ... -
Species traits and network structure predict the success and impacts of pollinator invasions
(NATURE PUBLISHING GROUP, 2018)Species invasions constitute a major and poorly understood threat to plant-pollinator systems. General theory predicting which factors drive species invasion success and subsequent effects on native ecosystems is particularly ... -
Spectral intensities in trivalent lanthanide systems: Applications to the Cs2NaDyCl6 and Cs2NaHoCl6 crystals
(, 2008-08-11)The main goal of this research work is to rationalize the rich vibronic structure of lanthanide type crystals, such as Cs2NaDyCl6 and Cs2NaHoCl6, in the space group Fm3m(Oh5). These systems are known to be highly relativistic ... -
Spectroscopic and photometric study of the eclipsing interacting binary V495 Centauri
(OXFORD UNIV PRESS, 2018)Double Periodic Variables (DPV) are among the new enigmas of semidetached eclipsing binaries. These are intermediate-mass binaries characterized by a long photometric period lasting on average 33 times the orbital period. ... -
Spin-lattice dynamics of surface vs core magnetization in Fe nanoparticles
(AIP Publishing, 2021-07-05)Magnetization of clusters is often simulated using atomistic spin dynamics for a fixed lattice. Coupled spin-lattice dynamics simulations of the magnetization of nanoparticles have, to date, neglected the change in the ... -
Spin-lattice-dynamics analysis of magnetic properties of iron under compression
(NATURE PORTFOLIO, 2023-08-31)Compression of a magnetic material leads to a change in its magnetic properties. We examine this effect using spin-lattice dynamics for the special case of bcc-Fe, using both single- and poly-crystalline Fe and a bicontinuous ... -
Spirometric values in healthy preschool children
(SOC CHILENA PEDIATRIA, 2019)Introduction. Spirometry is the most commonly used test to evaluate lung function. Foreign reference standards are currently available for preschool children. Objectives: 1. To measure spirometric variables in healthy ... -
Spring-Summer Drought Induces Extremely Low Radial Growth Reactions in North-Tyrrhenian Pinus pinea L.
(Universidade Federal Rural do Rio de Janeiro, Instituto de Florestas, 2020)Climate projections predict shifts in environmental conditions, with cascade effects on forest growth dynamics. As such, Pinus pinea L., an ecologically important low-elevation Mediterranean tree, can be threatened by ... -
Stable and unstable trajectories in a dipolar chain
(AMER PHYSICAL SOC, 2021-05-27)In classical mechanics, solutions can be classified according to their stability. Each of them is part of the possible trajectories of the system. However, the signatures of unstable solutions are hard to observe in an ... -
Stages and transitions in the development of tooth brushing skills in children of Mexican immigrant families: a qualitative study
(CIENCIAS, 2015)Objectives: Compared with white children, the oral health of Latino children in the United States is much worse. One factor contributing to oral health is tooth brushing. Few studies have addressed the formation of the ... -
Stages of change in the purchase of ultra-processed snacks among university students after the implementation of the chilean food law; a multi-center study
(ARCHIVOS LATINOAMERICANOS NUTRICION, 2021-05-23)The Objective is to determine the stages of change in the behavior of university students regarding the purchase of ultra-processed snacks consumed. Multi-center study (14 Chilean universities). The participants (4,807 ... -
Stimulated Raman adiabatic control of a nuclear spin in diamond
(American Physical Society, 2017)Coherent manipulation of nuclear spins is a highly desirable tool for both quantum metrology and quantum computation. However, most of the current techniques to control nuclear spins lack fast speed, impairing their ... -
Stochastic simulation of multiscale complex systems with PISKaS: A rule-based approach
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2018)Computational simulation is a widely employed methodology to study the dynamic behavior of complex systems. Although common approaches are based either on ordinary differential equations or stochastic differential equations, ...
