S-Expansion of Higher-Order Lie Algebras
(2009)By means of a generalization of the S-expansion method we construct a procedure to obtain expanded higher-order Lie algebras. It is shown that the direct product between an Abelian semigroup S and a higher-order Lie algebra ... -
Salmon farming vulnerability to climate change in southern Chile: understanding the biophysical, socioeconomic and governance links
(2019-05)Here, we describe an assessment of climate‐change vulnerability for the salmon farming sector in southern Chile using a model that combines semi‐quantitative measures of Exposure (risks), Sensitivity (economic and social ... -
SAS4P: Providing automatic smoking detection for a persuasive smoking cessation application
(2019-11)Smoking is the biggest avoidable health risk, causing millions of deaths per year worldwide. Persuasive applications are those designed to change a person’s behavior, usually in a specific way. Several mobile phone ... -
Satisfacción académica y prácticas pedagógicas percibidas por estudiantes de salud de Chile
(2019-10)Introducción. Las prácticas pedagógicas siguen siendo un fenómeno poco investigado, pese a su relevancia para la calidad de la formación universitaria. Objetivo. Analizar la relación entre las prácticas pedagógicas ... -
Scalar field quasinormal modes on asymptotically locally flat rotating black holes in three dimensions
(2019-03-27)The pure quadratic term of New Massive Gravity in three dimensions admits asymptotically locally flat, rotating black holes. These black holes are characterized by their mass and angular momentum, as well as by a hair of ... -
School networks to promote ICT competences among teachers. Case study in intercultural schools
(2014)The aim of this quantitative, exploratory and descriptive research is to know if teachers that work in intercultural contexts develop ICT competences by using virtual platforms. The innovation of the teaching-learning ... -
Scientific mapping of Coastal governance: global benchmarks and trends
(2022)This research panoramically and empirically reviews the scientific production on coastal governance studies, mapping global networks of countries, organizations, authors, themes, and journals as referents for this topic. ... -
Sea surface network optimization for tsunami forecasting in the near field: application to the 2015 Illapel earthquake
(2020-02)We propose a method for defining the optimal locations of a network of tsunameters in view of near real-time tsunami forecasting using sea surface data assimilation in the near and middle fields, just outside of the source ... -
Seasonal and interannual changes in reproductive parameters and eggs biochemical composition of the fishery resource Pleuroncodes monodon (Decapoda: Munididae) from the Humboldt Current System
(2020-01)Environmental variables are key drivers of reproductive traits in marine organisms, which can have significant economic consequences in commercial species. Pleuroncodes monodon is an important resource of the industrial ... -
Seasonal effects of the seeding on the growth of Chilean mussel (Mytilus edulis platensis, d'Orbigny 1846) cultivated in central Chile
(2014)This study presents a background on growing Mytilus edulis platensis, which were seeded on both summer and winter seasons. Surface longline systems were installed at a lower latitude zone than mussel aquaculture industries ... -
Secondary creep analysis of FG rotating cylinder with exponential, linear and quadratic volume reinforcement
(2022)Creep is an irreversible time-dependent deformation in which a material under constant mechanical stress and elevated temperature for a considerably prolonged period of time, starts to undergo permanent deformation. Creep ... -
Secuencia didáctica para escritura en colaboración en un entorno wiki: propuesta para estudiantes de Enseñanza Secundaria
(2012-10)En este artículo se presenta una propuesta de secuencia didáctica diseñada en conjunto por profesores universitarios y docentes del subsector de Lenguaje de Enseñanza Media de la Región del Bío Bío (Chile), cuyo objetivo ... -
Seeding of fragments of the agarophyte Gelidium lingulatum (Rhodophyta, Gelidiales) for the repopulation of lower levels of wave-exposed, intertidal rocky shores
(2019-06)Gelidium lingulatum is a frequent species at low intertidal levels of wave-exposed, rocky shores in central Chile. It is harvested from natural stands by artisanal fishermen and sold as raw material for the extraction of ... -
Segregation of SE Pacific and SW Atlantic southern blue whiting stocks: integrating evidence from complementary otolith microchemistry and parasite assemblage approaches
(2010)Southern blue whiting Micromesistius australis support one of the largest industrial fisheries in South America. Two main spawning/nursery grounds are known: one in the SW Atlantic Ocean (SWA), southwest from the Falkland ... -
Seismic and Coastal Vulnerability Assessment Model for Buildings in Chile
(2021)This article proposes a vulnerability assessment model for evaluating buildings’ expected seismic performance, as well as their vulnerability to tsunamis. The objective of this assessment is to provide appropriate information ... -
Seismic zonation and default suite of groundMotion records for time-history analysis in the North Island of New Zealand
(2012)A seismic zonation to be used in the selection of ground-motion records for time-history analysis of buildings in the North Island of New Zealand is presented. Both deaggregations of the probabilistic seismic hazard model ... -

Selective changes in the mechanical capacities of lower-body muscles after cycle-ergometer sprint training against heavy and light resistances
(2018-03)Purpose: To explore the feasibility of the linear force–velocity (F–V) modeling approach to detect selective changes of F–V parameters (ie, maximum force [F0], maximum velocity [V0], F–V slope [a], and maximum power [P0]) ... -
Selective effect of static stretching, concentric contractions, and a balance task on ankle force sense
(2019-01-17)Proper ankle motor control is critical for balance in the human body during functional activities such as standing, walking, and running. Different exercise modalities are often performed during the same training session ... -
Selective effect of static stretching, concentric contractions, and a one-leg balance task on ankle motion sense in young and older adults
(2019-06)Background: Being aware of ankle movement and motor control has a critical role in maintaining balance during functional activities such as standing, walking, and running. Since the somatosensory system declines with aging, ...
