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 ... -
Structural, electronic and catalytic properties of palladium nanoparticles supported on poly(ionic liquid)
(ELSEVIER SCIENCE BV, 2018)The structural, electronic and support effect on palladium nanoparticles (Pd NPs) prepared by sputtering deposition and chemical reduction of a Pd(II) precursor in/on a poly(ionic liquid) (PIL) was investigated in the ... -
Structure and vulnerability of the multi-interaction network in macrophyte-dominated lakes
(WILEY, 2020)The network approach is crucial to understand how ecosystems are structured and how they will respond to the disturbances (e.g. the current global change). We have recreated the multi-interaction network of a shallow ... -
Structure-Activity Relationships Based on 3D-QSAR CoMFA/CoMSIA and Design of Aryloxypropanol-Amine Agonists with Selectivity for the Human 3-Adrenergic Receptor and Anti-Obesity and Anti-Diabetic Profiles
(MDPI, 2018)The wide tissue distribution of the adrenergic 3 receptor makes it a potential target for the treatment of multiple pathologies such as diabetes, obesity, depression, overactive bladder (OAB), and cancer. Currently, there ... -
Study of the key biotic and abiotic parameters influencing ammonium removal from wastewaters by Fe3+-mediated anaerobic ammonium oxidation (Feammox)
(Elsevier Ltd., 2023-10)The release of ammonia (as NH4+) into water bodies causes serious environmental problems. Therefore, the removal of ammonia from wastewater effluents has become a worldwide concern. New autotrophic biological alternatives ... -
