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, ... -
Stock returns and liquidity risk in Chile
(UNIV AUTONOMA CARIBE-UAC, 2019)This study analyzes the impact of liquidity risk on the return of shares in the Chilean stock market during the period from January 2000 to July 2018. Many studies have focused on measuring this effect in developed markets ... -
Storage and retrieval of interacting photons in a Rydberg medium
(AMER PHYSICAL SOC, 2019)Storing interacting photons in ensembles of highly excited Rydberg atoms makes it possible to realize photon-photon gates. The efficiency of stopping and retrieving pairs of single-photon pulses in any Rydberg medium is, ... -
Strength Training to Prevent Falls in Older Adults: A Systematic Review with Meta-Analysis of Randomized Controlled Trials
(MDPI, 2021-07-31)We performed a systematic review with meta-analysis of randomized controlled trials (RCTs) to assess the effects of strength training (ST), as compared to alternative multimodal or unimodal exercise programs, on the number ... -
Strength Training versus Stretching for Improving Range of Motion: A Systematic Review and Meta-Analysis
(MDPI, 2021-05-11)Background: Stretching is known to improve range of motion (ROM), and evidence has suggested that strength training (ST) is effective too. However, it is unclear whether its efficacy is comparable to stretching. The goal ... -
Stress and salivary telomere length in the second half of life: A comparison of life-course models
(ELSEVIER SCI LTD, 2019)Background: Previous research has explored the relationship between childhood and adulthood stressful life events (SLEs) and adult salivary telomere length (TL), but no research to date has tested different life-course ... -
Stress, sleep, and sex: A review of endocrinological research in Octodon degus
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2019)The Common Degu (Octodon degus) is a small rodent endemic to central Chile. It has become an important model for comparative vertebrate endocrinology because of several uncommon life-history features - it is diurnal, shows ... -
StructRNAfinder: an automated pipeline and web server for RNA families prediction
(Chile. Universidad Mayor, 2018-02-17)The function of many noncoding RNAs (ncRNAs) depend upon their secondary structures. Over the last decades, several methodologies have been developed to predict such structures or to use them to functionally annotate RNAs ... -
Structural and functional brain changes in people with knee osteoarthritis: a scoping review
(PEERJ INC, 2023-09-07)Background. Knee osteoarthritis is a highly prevalent disease worldwide that leads to functional disability and chronic pain. It has been shown that not only changes are generated at the joint level in these individuals, ... -
Structural bases that underline Trypanosoma cruzi calreticulin proinfective, antiangiogenic and antitumor properties
(Urban und Fischer Verlag GmbH und Co. KG, 2020-01)Microbes have developed mechanisms to resist the host immune defenses and some elicit antitumor immune responses. About 6 million people are infected with Trypanosoma cruzi, the protozoan agent of Chagas' disease, the sixth ... -
Structural Relaxation and Crystalline Phase Effects on the Exchange Bias Phenomenon in FeF2/Fe Core/Shell Nanoparticles
(John Wiley and Sons Ltd, 2020-09)In this study, the power of first-principles methods along with molecular dynamics and atomistic Monte Carlo simulations is employed to elucidate the effects of the structural relaxation on the exchange bias (EB) behavior ... -
