(Universidad de Chile, 2020)Due to the increasing energy demand predicted for the following 30 years, the integration of renewable energy to the global energy grid, is considered one of the most important strategies to fight climate change. Since ...
-
(Universidad de Chile, 2022)Las bacterias nadan gracias al movimiento de sus flagelos. Esa afirmación se ramifica de muchas maneras, ya que las bacterias tienen diferentes formas corporales y tipos de flagelos. Además, el entorno tiene un papel ...
-
(Springer, 2015)Let S be a set of 2n points on a circle such that for each point p∈S also its antipodal (mirrored with respect to the circle center) point p′ belongs to S. A polygon P of size n is called antipodal if it consists of precisely ...
-
(Springer, 2020)The ordinary differential equation x˙ (t) = f(x(t)), t ≥ 0, for f measurable, is not sufficiently regular to guarantee existence of solutions. To remedy this we may relax the problem by replacing the function f with its ...
-
(Wiley-VCH Verlag, 2019)In the present study, 20 psychrotolerant yeast species isolated from the soils of King George Island in the sub-Antarctic region were evaluated for the production of extracellular gelatinase, an enzyme with high potential ...
-
(Universidad Nacional de Colombia. Facultad de Ingeniería, 2021)This study aims to characterize a series of highrise reinforced concrete wall buildings located in Antofagasta, Chile, by means of a set of structural indexes commonly used in professional activities in our country and ...
-
(2004)Polycrystalline calcium titanate films up to 300 nm in thickness were grown on titanium and Ti6Al4V substrates by the hydrothermal–electrochemical technique in an autoclave at 200 ◦C. The films examined by x-ray ...
-
(2013)Context. Despite increasing research in massive star formation, little is known about its earliest stages. Infrared dark clouds (IRDCs) are cold, dense and massive enough to harbour the sites of future high-mass star ...
-
(Springer, 2013)We give a necessary and sufficient condition for a difference of convex (DC, for short) functions, defined on a normed space, to be Lipschitz continuous. Our criterion relies on the intersection of the ε-subdifferentials ...
-
(EDP Sciences, 2018)Context. The circumstellar disk of the Herbig Fe star HD 142527 is host to several remarkable features including a warped inner disk, a 120 au-wide annular gap, a prominent dust trap and several spiral arms. A low-mass ...
-
(IOP Publishing Ltd, 2018)The construction of affine interval exchange maps (IEMs) with wandering intervals that are semi-conjugate to a given self-similar IEM is strongly related to the existence of the so-called minimal sequences associated with ...
-
(Elsevier, 2020)Pd-loaded tungsten oxide thin films have been successfully fabricated by direct UV irradiation of bis(beta-diketonate)dioxotungsten(VI) and Pd(II) precursor complexes spin-coated on Si(100) substrates. X-ray diffraction ...

Characterization of spatiotemporal chaos in a Kerr optical frequency comb and in all fiber cavities (OSA - The Optical Society, 2017)Complex spatiotemporal dynamics have been a subject of recent experimental investigations in optical frequency comb microresonators and in driven fiber cavities with Kerr-type media. We show that this complex behavior has ...
-
(Royal Meteorological Society, 2015)The 1976-1977 cold-to-warm sea surface temperature (SST) shift in the tropical Pacific Ocean, which has been associated with a phase change of the Pacific Decadal Oscillation (PDO) index, separated a 'La Nina-like' decadal ...
-
(Wiley, 2018-08)Since the last century, several geological and geophysical studies have been developed in the Santiago Basin to understand its morphology and tectonic evolution. However, some uncertainties regarding sedimentary fill ...
-
(Elsevier, 2016)A structural characterization of the hydrothermal-volcanic field associated with the Tinguiririca Volcanic Complex had been performed by combining passive seismic tomography and structural geology. This complex corresponds ...
-
(Universidad de Chile, 2023)Los blazares son un tipo de galaxia de núcleo activo con jets relativistas orientados muy cercano a la línea de visión entre el objeto y el observador. Estos objetos emiten radiación sobre todo el espectro electromagnético, ...
-
(2013)Employing nematic liquid crystals in a homeotropic cell with a photosensitive wall, dissipative vortex pairs are selectively induced by external illumination and the interaction law is characterized for pairs of ...
-
(Amer Mathematical Soc, 2016)We establish subdifferential calculus rules for the sum of convex functions defined on normed spaces. This is achieved by means of a condition relying on the continuity behaviour of the inf-convolution of their corresponding ...
-
(Springer New York LLC, 2019)© 2018, Springer Science+Business Media, LLC, part of Springer Nature. Two criteria for the robust quasiconvexity of lower semicontinuous functions are established in terms of Fréchet subdifferentials in Asplund spaces. ...
