(CAMBRIDGE UNIV PRESS, 2008-04)In this paper, a group shift is an expansive action of Z(d) on a compact metrizable zero-dimensional group by continuous automorphisms. All group shifts factor topologically onto equal-entropy Bernoulli shifts; abelian ...
-
(Universidad de Chile, Facultad de Filosofia y Humanidades, Departamento de Literatura, 2019)The article analyzes the speech of the Zig-Zag magazine in relation to the city of Arica, as a collaborator in a propaganda policy of Chileanization, in the context in which Peru and Chile must prepare for the Treaty that ...
-
(American Physical Society, 2014)Liquid crystals displays with tailoring electrodes exhibit complex spatiotemporal dynamics when a large voltage is applied. We report experimental observations of the appearance of a programmable zig-zag lattice using ...
-
(Elsevier, 2015)Zinc oxide nanoparticles with different amounts of incorporated silver (ZnO:Ag; 0.6, 3, 6, and 9 at.% Ag) have been successfully synthesized by a simple sol gel method. The effect of Ag content on the properties of ZnO ...
-
(Taylor & Francis, 2012)The synthesis, characterization, and properties of three types of one-dimensional zinc oxide nanostructures are described. They were obtained by solvothermal treatment of nanometric zinc oxide as zinc ion source (i.e., ...
-
(Elsevier, 2020)A comprehensive understanding of the magmatic system evolution and petrogenetic environment is crucial for the correct interpretation of magmatic zircon age spectra. In the Central Andes, a protracted Late Paleozoic period ...
-
(Elsevier, 2017)The ultramafic massifs of the Serrania de Ronda (namely Ronda, Ojen and Carratraca) are portions of Proterozoic (similar to 1.2-1.8 Ga) subcontinental lithospheric mantle (SCLM) affected by partial melting and infiltration ...
-
(Elsevier, 2015)A ternary ZnO/Ag/CdO nanocomposite was synthesized using thermal decomposition method. The resulting nanocomposite was characterized by X-ray diffraction, field emission scanning electron microscopy, transmission electron ...
-
(Universidad de Chile, 2014)El sector Los Bronces, perteneciente a la compañía minera Anglo American, se ubica en la franja metalogénica del Mio-Plioceno de Chile Central alojado en lado oriental del Batolito San Francisco a unos 65 km al noreste de ...
-
(Academic Press Inc., 2019)Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by motor neuron death. A 20% of familial ALS cases are associated with mutations in the gene coding for superoxide dismutase 1 (SOD1). The ...
-
(NLM (Medline), 2019)Under realistic environmental conditions, heuristic-based data association and map management routines often result in divergent map and trajectory estimates in robotic Simultaneous Localization And Mapping (SLAM). To ...
-
(Springer, 2018)In this paper we prove a Law of Large Numbers for the number of δ-records in a sequence of random variables with an underlying trend. Our results generalizes results appeared in the literature for the i.i.d. case and for ...
-
(Royal Society of Chemistry, 2019)The mechanism of the SNAr reactions between 1-halo-2,4-dinitrobenzenes and amines was revisited by means of DFT calculations. Remarkably and contrary to the traditional text-book perspective, the dehalogenation of ...
-
(Springer International Publishing, 2019)In this paper we study a new class of functions, which we call (ω, c) -pseudo periodic functions. This collection includes pseudo periodic, pseudo anti-periodic, pseudo Bloch-periodic, and unbounded functions. We prove ...

(ω, c)-periodic functions and mild solutions to abstract fractional integro-differential equations (Univ Szeged, 2018)In this paper we study a new class of functions, which we call (omega, c)-periodic functions. This collection includes periodic, anti-periodic, Bloch and unbounded functions. We prove that the set conformed by these functions ...
