    • Kaplan, M. R.; Strelin, J. A.; Schaefer, J. M.; Peltier, C.; Martini, M. A.; Flores, E.; Winckler, G.; Schwartz, R. (Elsevier, 2020)
      We obtained 49 new Be-10 ages that document the activity of the former Northern Antarctic Peninsula Ice Sheet, and subsequently the James Ross Island Ice Cap and nearby glaciers, from the end of the last glacial period ...
    • Sagredo, Esteban A.; Reynhout, Scott Andrew; Kaplan, Michael R.; Aravena, Juan C.; Araya, Paola S.; Luckman, Brian H.; Schwartz, Roseanne; Schaefer, Joerg M. (Frontiers Media, 2021)
      The causes underlying Holocene glacier fluctuations remain elusive, despite decades of research efforts. Cosmogenic nuclide dating has allowed systematic study and thus improved knowledge of glacier-climate dynamics ...
    • Ren X., Astudillo P., Graf U.U., Hills R.E., Jorquera S., Nikolic B., Parshley S.C., Reyes N., Weikert L. (SPIE, 2020)
    • Pinilla, P.; Tazzari, M.; Pascucci, I.; Youdin, A. N.; Garufi, A.; Manara, C. F.; Testi, L.; Van der Plas, Gerrit; Barenfeld, S. A.; Canovas, H.; Cox, E. G.; Hendler, N. P.; Pérez, L. M.; van der Marel, N. (Iop Publishing LTD., 2018-05-20)
      We analyze the dust morphology of 29 transition disks (TDs) observed with Atacama Large (sub-)Millimeter Array (ALMA) at (sub-)millimeter emission. We perform the analysis in the visibility plane to characterize the total ...
    • Seleznev, A. F.; Carraro, Giovanni; Costa Hechenleitner, Edgardo; Loktin, A. V. (Elsevier, 2010)
      We present homogeneous V, I CCD photometry of nine stellar fields in the two inner quadrants of the Galactic plane. The lines-of-view to most of these fields aim in the direction of the very inner Galaxy, where the ...
    • Baffico Haramoto, Leonardo; Conca Rosende, Carlos; Rajesh, M. (ROYAL SOC EDINBURGH, 2006)
      In this article we study the asymptotic behaviour of the eigenvalues of a family of nonlinear monotone elliptic operators of the form A(epsilon) = - div(a(epsilon) (x, del u)), which are sub-differentials of even, positively ...
    • Baffico Haramoto, Leonardo; Conca Rosende, Carlos (1999)
      In this paper we study a simplified model of the behavior of a 3-D solid made from two elastic homogeneous materials separated by a rapidly oscillating interface. We study the asymptotic beha¨ior of the solution of such ...
    • Baffico Haramoto, Leonardo; Grandmont, C.; Maday, Y.; Osses Alvarado, Axel (SIAM PUBLICATIONS, 2008)
      We study the asymptotic behavior of a system modeling a composite material made of an elastic periodically perforated support, with period epsilon > 0, and a perfect gas placed in each of these perforations, as epsilon ...
    • Conca Rosende, Carlos; Vanninathan, Muthusamy (1997-12)
      In this paper, the classical problem of homogenization of elliptic operators in arbitrary domains with periodically oscillating coe cients is considered. Using Bloch wave decomposition, a new proof of convergence is ...
    • Pastén Rivera, Rodrigo Javier (Universidad de Chile, 2018)
      El presente trabajo de tesis tiene como objetivo general homologar las prácticas operacionales de los diversos grupos de trabajo y estandarizar los procesos en la planta concentradora de Minera Los Pelambres con el fin de ...
    • Ebrahimi-Fard, Kurusch; Patras, Frédéric; Tapia, Nikolas; Zambotti, Lorenzo (Oxford University Press, 2020)
      We present an approach to cumulant–moment relations and Wick polynomials based on extensive use of convolution products of linear functionals on a coalgebra. This allows, in particular, to understand the construction ...
    • Sandoval Alcocer, Juan (Universidad de Chile, 2016)
      Los cambios continuos en el código fuente de un programa pueden inadvertidamente introducir una regresión de rendimiento en tiempo de ejecución. Dichas regresiones se refieren a situaciones donde el rendimiento de un ...
    • Montecinos Cuadros, Hermes Andrés (Universidad de Chile, 2012)
      La formación de etringita retardada (DEF) es un fenómeno expansivo que se origina en estructuras de hormigón sometidas a altos niveles de temperatura (>70°C) durante su etapa inicial de curado, esto puede ocurrir en las ...
    • Kruehler, T.; Kuncarayakti, H.; Schady, P.; Anderson, J. P.; Galbany, Lluis; Gensior, J. (EDP Sciences, 2017)
      Spatially resolved spectroscopy of the environments of explosive transients carries detailed information about the physical properties of the stellar population that gave rise to the explosion, and thus the progenitor ...
    • Neveu VanMalle, M.; Queloz, D.; Anderson, D.; Brown, D.; Cameron, A. Collier; Delrez, L.; Diaz, R.; Gillon, M.; Hellier, C.; Jehin, E.; Lister, T.; Pepe, F.; Rojo Rubke, Patricio; Segransan, D.; Triaud, A.; Turner, O.; Udry, S. (EDP SCIENCES, 2016)
      We report the discovery of two additional planetary companions to WASP-41 and WASP-47. WASP-41 c is a planet of minimum mass 3.18 +/-0.20 M-Jup and eccentricity 0.29 +/- 0.02, and it orbits in 421 +/- 2 days. WASP-47 c is ...
    • Guzmán, Andrés; Garay Brignardello, Guido; Brooks, Kate J.; Rathborne, Jill; Güsten, Rolf (The American Astronomical Society, 2011-08-01)
      We report molecular line observations in the CO J = 3→2, 6→5, and 7→6 transitions, made using the Atacama Pathfinder Experiment Telescope, toward the massive and dense core IRAS 16562−3959. This core harbors a string of ...
    • Callaú, Oscar; Robbes, Romain; Tanter, Éric Pierre; Röthlisberger, David (Springer, 2013)
      The dynamic and reflective features of programming languages are powerful constructs that programmers often mention as extremely useful. However, the ability to modify a program at runtime can be both a boon—in terms of ...
    • Prieto, Joaquín; Escala Astorquiza, Andrés; Volonteri, Marta; Dubois, Yohan (Institute of Physics Publishing, 2017)
      Using cosmological hydrodynamical simulations, we study the effect of supernova (SN) and active galactic nucleus (AGN) feedback on the mass transport (MT) of gas onto galactic nuclei and the black hole (BH) growth down to ...
    • Hora, Andre; Robbes, Romain; Valente, Marco Tulio; Anquetil, Nicolas; Etien, Anne; Ducasse, Stephane (Springer, 2018)
      Software engineering research now considers that no system is an island, but it is part of an ecosystem involving other systems, developers, and users. When a framework or a library evolves, its clients often must adapt. ...
    • Leyton, F.; Ruiz Tapia, Sergio; Baez, J.; Meneses, G.; Madariaga, R. (Blackwell Publishing Ltd, 2018)
      Fast and reliable characterization of earthquakes can provide vital information to the population, even reducing the effects of strong shaking produced by them. In this study, we explore the minimum time required to estimate ...
