Search for associations containing young stars (SACY) VIII. An updated census of spectroscopic binary systems exhibiting hints of non-universal multiplicity among their associations
(European Southern Observatory (ESO), 2021)Context. Nearby young associations offer one of the best opportunities for a detailed study of the properties of young stellar and substellar objects thanks to their proximity (<200 pc) and age (∼5−150 Myr). Previous works ... -
The HD 98800 quadruple pre-main sequence system Towards full orbital characterisation using long-baseline infrared interferometry
(European Southern Observatory (ESO), 2021)Context. HD 98800 is a young (∼10 Myr old) and nearby (∼45 pc) quadruple system, composed of two spectroscopic binaries orbiting around each other (AaAb and BaBb), with a gas-rich disk in polar configuration around BaBb. ... -
Entre obreros y empleados. Los inicios de la lucha por el reconocimiento en la industria hotelera y gastronómica (1927-1949)
(Universidad De Chile, 2021)El presente artículo analiza el desarrollo del movimiento gremial hotelero y gastronómico entre 1927 y 1949. Este movimiento no ha sido estudiado por la historiografía social, abriéndose un campo de análisis provechoso ... -
El turismo y los inicios de una industria en Chile (1910-1950)
(Instituto De Investigaciones Dr. José María Luis Mora, 2021)En este artículo se reconstruyen, de manera exploratoria, los antecedentes estadísticos del desarrollo del turismo en Chile entre 1910 y 1950, que permiten dimensionar sus alcances como actividad económica importante. Se ... -
¿Es la teoría ideal de Rawls demasiado realista? Dibujando los límites de la igualdad
(Corporacion Filosofía Y Sociedad, 2021)En este trabajo evaluamos si la justicia como equidad le concede demasiado a la realidad social, colapsando el ideal normativo de la teoría en la facticidad. Para lograrlo, distinguimos las teorías ideales de las no ideales ... -
Quantifying the Occurrence of Record Hot Years Through Normalized Warming Trends
(American Geophysical Union, 2021)Surface air temperature trends and extreme events are of global concern and they are related. Here, we show that the occurrence of record hot years over different latitudes from 1960 to 2019 are more strongly correlated ... -
Expression of glucose transporter-2 in murine retina: Evidence for glucose transport from horizontal cells to photoreceptor synapses
(Wiley, 2022)The retina has the highest relative energy consumption of any tissue, depending on a steady supply of glucose from the bloodstream. Glucose uptake is mediated by specific transporters whose regulation and expression are ... -
Diversity of neuronal activity is provided by hybrid synapses
(Springer, 2021)The coexistence of electrical and chemical synaptic communication among excitatory cells has been evidenced by neuroscientists. Nevertheless, theoretical understanding of hybrid synaptic connections in diverse dynamical ... -
Chile, tierra de encanto (1937). La propaganda turística en los inicios del turismo de masas
(Universidad De Chile, 2021)Este artículo analiza el documental de viaje sobre Chile del realizador norteamericano James FitzPatrick, titulado Chile, tierra de encanto (1937). A partir de él se comprenden los alcances de la imagen turística sobre ... -
Is Rhodamine a good tracer to predict coal transport in water?
(Universidad Católica De La Santísima Concepción, 2021)A simple and low-cost experimental procedure to compare the mixing and transport of two substances in water is presented in this paper, aiming to investigate if rhodamine can predict the fate of coal transport in water. ... -
Plasticity in Colorectal Cancer: Why Cancer Cells Differentiate
(MDPI, 2021)The cancer stem cell hypothesis poses that the bulk of differentiated cells are non-tumorigenic and only a subset of cells with self-renewal capabilities drive tumor initiation and progression. This means that differentiation ... -
Reduced Oligodendrocyte Precursor Cell Impairs Astrocytic Development in Early Life Stress
(Wiley, 2021)In animals, circadian clocks impose a daily rhythmicity to many behaviors and physiological processes. At the molecular level, circadian rhythms are driven by intracellular transcriptional/translational feedback loops ... -
Inhibition of Caco-2 and MCF-7 cancer cells using chalcones: synthesis, biological evaluation and computational study
(Taylor & Francis, 2021)Cancer is the second death cause worldwide, with breast and colon cancer among the most prevalent types. Traditional treatment strategies have several side effects that inspire the development of novel anticancer agents ... -

GASP XXXIII. The ability of spatially resolved data to distinguish among the diferent physical mechanisms afecting galaxies in low-density environments
(American Astronomical Society (Aas), 2021)Galaxies inhabit a wide range of environments and therefore are affected by different physical mechanisms. Spatially resolved maps combined with the knowledge of the hosting environment are very powerful for classifying ... -
Determination of the superoutburst cycle lengths of 206 SU UMa-type dwarf novae
(Royal Astronomical Society, 2021)SU UMa stars are characterized by ‘superoutbursts’, which are brighter at maximum light and which last much longer than the more frequent ‘ordinary’ outbursts of these dwarf novae. Although there are now more than 1180 SU ... -
Looking into the cradle of the grave: J22564-5910, a young post-merger hot subdwarf?
(European Southern Observatory (ESO), 2021)Context. We present the discovery of J22564–5910, a new type of hot subdwarf (sdB) which shows evidence of gas present in the system and it has shallow, multi-peaked hydrogen and helium lines which vary in shape over time. ... -
Ultrasound assisted synthesis and cytotoxicity evaluation of known 2′ ,4′ -dihydroxychalcone derivatives against cancer cell lines
(Elsevier, 2021)This work reports on the development of an efficient and ecofriendly ultrasound assisted method for the high yield synthesis (70.0–94.0%) of eighteen oxyalkylated derivatives of 2′ ,4′ -dihydroxychalcone. Synthesized ... -
