(Elsevier, 2020)Hartsfield and Ringel in 1990 conjectured that any connected graph with q >= 2 edges has an edge labeling f with labels in the set {1,..., q}, such that for every two distinct vertices u and v, f(u) not equal= f(v), where ...

(Copernicus Gesellschaft MBH, 2020)Detecting and understanding historical changes in the frequency of geo-climatic hazards (G-CHs) is crucial for the quantification of current hazards and project them into the future. Here we focus in the eastern subtropical ...
-
(Universidad de Chile, 2020)El objetivo de esta tesis consiste en sintetizar catalizadores soportados del tipo xNi@UIO-66, utilizando redes metal-orgánicas cristalinas altamente porosas de Zr como soporte para la síntesis de nanopartículas de Ni ...
-
(Universidad de Chile, 2020)En la industria de semiconductores actual existe una gran demanda por productos de bajo consumo debido al constante desarrollo de la tecnología móvil, así como aplicaciones con restricciones fuertes de potencia como la ...

(American Institute of Physics, 2020)Homogeneously driven dynamical systems exhibit multistability. Depending on the initial conditions, fronts present a rich dynamical behavior between equilibria. Qualitatively, this phenomenology is persistent under spatially ...
-
(Geological Soc Publ House, 2020)The scarce Eocene geological record in the Andean region of Central Chile (c. 33.6 degrees S) is represented by the Estratos del Cordon de los Ratones unit. This is a c. 450 m thick, mainly volcanic, continental series ...

(American Institute of Physics, 2020)Distributed generation (DG) has experienced extraordinary growth in installed capacity in many countries. DG can have a significant impact on both the investment and operational costs of distribution feeders. However, in ...
-
(Elsevier, 2020)In this study, we analyze 100 crustal Precordilleran earthquakes recorded in 2008 and 2009 by 52 broadband seismic stations from the SIEMBRA and ESP, two temporary experiments deployed in the Pampean flat slab region, ...
-
(Wiley, 2020)Skeletal muscle atrophy is characterized by the degradation of myofibrillar proteins, such as myosin heavy chain or troponin. An increase in the expression of two muscle-specific E3 ligases, atrogin-1 and MuRF-1, and ...
-
(Springer, 2020)The heap leaching process has been widely used for recovering different metals since its first application at the end of the 1960s. In Chile, copper production via heap leaching has accounted for between 30 and 40% of ...
-
(Elsevier, 2020)The supply of natural gas is generally based on contracts that are signed prior to the use of this fuel for power generation. Scarcity of natural gas in systems where a share of electricity demand is supplied with gas ...
-
(Oxford University Press, 2020)Real-order generalization of dissipativeness and passivity concepts are presented in this paper. They are characterized as properties of a system; that is, they are independent of the system's internal representation and ...
-
(Elsevier, 2020)The temporal decay pattern of seismicity following rock bursts and large magnitude events is studied for aftershock sequences in several mines in Ontario, Canada. The decay phenomenon is described by the so – called Modified ...
-
(Universidad de Chile, 2019)El preacondicionamiento (PA), sea a través de la técnica de fracturamiento hidraúlico (FH) y/o debilitamiento dinámico con explosivos (DDE), busca reducir la competencia del macizo rocoso al generar nuevas fracturas. ...
-
(Universidad de Chile, 2020)El presente trabajo de título desarrolla un análisis de los factores contribuyentes en la pérdida del ancho de berma en la Fase F10N de Mina Los Pelambres, con el objetivo de identificar las causas que contribuyen a la ...

(American Physical Society, 2020)Nonequilibrium systems exhibit particle-type solutions. Oscillons are one of the best-known localized states of systems with time-dependent forcing or parametrically driven systems. We investigate the transition from ...
