      Little is known about how old-growth and massive forests are responding to environmental change. We investigated tree-ring growth and carbon isotopes of the long-lived and high biomass Fitzroya cupressoides in two stands ...

    • Menares, Camilo; Gallardo Klenner, Laura; Kanakidou, María; Seguel, Rodrigo; Huneeus Lagos, Nicolás (Taylor and Francis, 2020)
      Despite the decline in partially (PM10) and fully (PM2.5) inhalable particles observed in recent decades, Santiago in Chile shows high levels of particle and ozone pollution. Attainment plans have emphasized measures ...
    • Iusem, Alfredo N.; Jofré Cáceres, René; Thompson, Philip (INFORMS Inst.for Operations Res.and the Management Sciences, 2019)
      We consider stochastic variational inequalities (VIs) with monotone operators where the feasible set is an intersection of a large number of convex sets. We propose a stochastic approximation method with incremental ...
    • Correa Haeussler, José; Feuilloley, Laurent; Pérez Lantero, Pablo; Soto San Martín, José (Springer, 2015)
      Given a set of n axis-parallel rectangles in the plane, finding a maximum independent set (MIS), amaximumweighted independent set (WMIS), and aminimum hitting set (MHS), are basic problems in computational geometry and ...
    • Salo, Ville; Torma, Ilkka (Springer, 2017)
      In the setting of symbolic dynamics on discrete finitely generated infinite groups, we define a model of finite automata with multiple independent heads that walk on Cayley graphs, called group-walking automata, and use ...
    • Cucchiara, A.; Prochaska, J. X.; Zhu, G.; Ménard, B.; Fynbo, J. P. U.; Fox, D. B.; Chen, H. W.; Cooksey, K. L.; Cenko, S. B.; Perley, D.; Bloom, J. S.; Berger, E.; Tanvir, N. R.; D’Elia, V.; Lopez, S.; Chornock, R.; De Jaeger, Thomas (The American Astronomical Society, 2013-08)
      In 2006, Prochter et al. reported a statistically significant enhancement of very strong Mgii absorption systems intervening the sight lines to gamma-ray bursts (GRBs) relative to the incidence of such absorption along ...
    • Bachir, Mohammed; Flores, Gonzalo (Rocky MT Math Consortiumariz State Univ, Dept Math, 2020)
      Let X, Y be asymmetric normed spaces and Lc(X, Y ) the convex cone of all linear continuous operators from X to Y . It is known that in general, Lc(X, Y ) is not a vector space. The aim of this note is to give, using ...
    • Barbay, Jérémy; Olivares, Andrés (Springer Verlag, 2018)
      There are efficient dynamic programming solutions to the computation of the Edit Distance from S ∈in [1..σ]n to T ∈in [1..σ]m, for many natural subsets of edit operations, typically in time within O(nm) in the worst-case ...
    • Maleki, Mohammad; Emery, Xavier; Mery, Nadia (MDPI AG, 2017)
      Geostatistics offers a set of methods for modeling, predicting, or simulating geological domains in space. In addition of being an input of some of these methods, indicator direct and cross-variograms convey valuable ...
    • Kracht Gajardo, Willy; Hunt, C. (Elsevier, 2016)
      The local critical coalescence concentration l-CCC presents a relationship between frother concentration and the gas flow rate Q(g)' at which coalescence starts to occur at a capillary tube. Such a relationship is used in ...
    • Maldonado, Karin; Newsome, Seth D.; Razeto Barry, Pablo; Ríos, Juan Manuel; Piriz, Gabriela; Sabat Kirkwood, Alejandro Pablo (Blackwell Publishing Ltd, 2019)
      © 2018 John Wiley & Sons Ltd/CNRS Individual diet specialisation (IS) is frequent in many animal taxa and affects population and community dynamics. The niche variation hypothesis (NVH) predicts that broader population ...
    • León Castro, Ernesto; Avilés-Ochoa, Ezequiel; Merigó Lindahl, José (John Wiley and Sons Ltd, 2018)
      This paper presents the induced heavy ordered weighted moving average (IHOWMA) operator. It is an aggregation operator that uses the main characteristics of three well-known techniques: the moving average, induced operator, ...
    • Mira Gebauer, Nicolás F.; Rojo Olea, Erick F.; Mendoza Araya, Patricio A. (IEEE, 2017)
      The presence of both electronic-converter-based and rotating-machine-based energy sources in microgrids poses a challenge for its stable operation. Most of the stability studies in microgrids have been focused on the ...
    • Duarte Mermoud, Manuel; Travieso Torres, Juan Carlos; Pelissier, Ian S.; González, Humberto A. (John Wiley, 2012-01)
      In this paper two new schemes for induction motor control are proposed and compared. Both approaches are based on the concept of adaptive passivity. First, a technique using the scheme of field oriented control (FOC) is ...
    • Valenzuela Fernández, Leslier; Nicolas, Carolina; Merigó Lindahl, José; Arroyo-Cañada, Francisco Javier (Emerald Group Publishing Ltd., 2019)
      © 2018, Emerald Publishing Limited. Purpose: The purpose of this paper is to determine the most influential countries and universities that have contributed to science in the field of industrial marketing research during ...
    • Contreras Guajardo, Dante; Otero, Gabriel; Díaz, Juan D.; Suárez, Nicolás (Elsevier B.V., 2019)
      Long-standing literature argues that social capital is closely implicated in labour market outcomes. However, this hypothesis has yet to be tested in Latin America, the most unequal region in the world. We focus on Chile, ...
    • Rojas, N. O.; Argentina, Mederic; Cerda, E.; Tirapegui Zurbano, Enrique (The American Physical Society, 2010)
      Thin fluid films can have surprising behavior depending on the boundary conditions enforced, the energy input and the specific Reynolds number of the fluid motion. Here we study the equations of motion for a thin fluid ...
    • Contreras, Yanett; Sanhueza, Patricio; Jackson, James M.; Guzmán, Andrés E.; Longmore, Steven; Garay Brignardello, Guido; Zhang, Qizhou; Quang, Nguyen-Lu'o'Ng; Tatematsu, Ken'ichi; Nakamura, Fumitaka; Sakai, Takeshi; Ohashi, Satoshi; Liu, Tie; Saito, Masao; Gómez, Laura; Rathborne, Jill; Whitaker, Scott (IOP Publishing, 2018-07)
      Using Galactic Plane surveys, we have selected a massive (1200M circle dot), cold (14 K) 3.6-70 mu m dark IRDC, G331.372-00.116. This infrared dark cloud (IRDC) has the potential to form high-mass stars, and given the ...
    • Lo, N.; Wiles, B.; Redman, M.; Cunningham, M.; Bains, I.; Jones, P.; Burton, M.; Bronfman Aguiló, Leonardo (Royal Astronomical Society, 2015)
      We present molecular line imaging observations of three massive molecular outflow sources, G333.6–0.2, G333.1–0.4, and G332.8–0.5, all of which also show evidence for infall, within the G333 giant molecular cloud (GMC). ...
