    • Transition from nonradiative to radiative oscillons in parametrically driven systems 
      Álvarez Socorro, Alejandro J.; Berríos Caro, Ernesto; Clerc Gavilán, Marcel G.; León, Alejandro O. (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 ...
    • Time use: The role of sleep 
      Jara Díaz, Sergio R.; Rosales Salas, Jorge (Elsevier, 2020)
      Time use models have been used to estimate the value of leisure - one of the components of the value of travel time savings - usually accepting that sleep duration is an exogenous variable. In this paper, we depart from ...
    • The origin of Asian monsoons: a modelling perspective 
      Tardif, Delphine; Fluteau, Frédéric; Donnadieu, Yannick; Le Hir, Guillaume; Ladant, Jean-Baptiste; Sepulchre, Pierre; Licht, Alexis; Poblete Gómez, Fernando; Dupont-Nivet, Guillaume (Copernicus Gesellschaft MHB, 2020)
      The Cenozoic inception and development of the Asian monsoons remain unclear and have generated much debate, as several hypotheses regarding circulation patterns at work in Asia during the Eocene have been proposed in the ...

C.; Morales, N.; Pallé, E.; Pedraz, S.; Rodríguez, E.; Rodríguez López, C.; Zechmeister, M. (EDP Sciences, 2020)
      Context. The nearby ultra-compact multiplanetary system YZ Ceti consists of at least three planets, and a fourth tentative signal. The orbital period of each planet is the subject of discussion in the literature due to ...
    • The 21 May 1960 M-w 8.1 Concepción Earthquake: A Deep Megathrust Foreshock That Started the 1960 Central-South ... 
      Ojeda Vargas, Javier; Ruiz Tapia, Sergio; Campo, Francisco del; Carvajal, Matías (Seismological Society of America, 2020)
      One of the most notable seismic sequences in modern times was recorded in May 1960 along the southern Chilean subduction zone. The sequence started on 21 May with the M-w 8.1 Concepcion earthquake; 33 hr later the M-w 9.5 ...
    • Simulation of Synthetic Exploration and Geometallurgical Database of Porphyry Copper Deposits for Educational ... 
      Garrido, Mauricio; Sepúlveda, Exequiel; Ortiz, Julián; Townley Callejas, Brian (Springer, 2020)
      The access to real geometallurgical data is very limited in practice, making it difficult for practitioners, researchers and students to test methods, models and reproduce results in the field of geometallurgy. The aim of ...
    • Predicting nationwide obesity from food sales using machine learning 
      Dunstan, Jocelyn; Aguirre Jerez, Marcela; Bastías García, Magdalena; Nau, Claudia; Glass, Thomas A.; Tobar, Felipe (SAGE, 2020)
      The obesity epidemic progresses everywhere across the globe, and implementing frequent nationwide surveys to measure the percentage of obese population is costly. Conversely, country-level food sales information can be ...
    • Positive solutions for systems of quasilinear equations with non-homogeneous operators and weights 
      García Huidobro, Marta; Manasevich Tolosa, Raúl; Tanaka, Satoshi (Walter de Gruyter, 2020)
      In this paper we deal with positive radially symmetric solutions for a boundary value problem containing a strongly nonlinear operator. The proof of existence of positive solutions that we give uses the blow-up method as ...
    • Patterns in the Multiwavelength Behavior of Candidate Neutrino Blazars 
      Franckowiak, A.; Garrappa, S.; Paliya, V.; Shappee, B.; Stein, R.; Strotjohann, N. L.; Kowalski, M.; Buson, S.; Kiehlmann, S.; Max-Moerbeck Astudillo, Walter; Angioni, R. (IOP Publishing, 2020)
      Motivated by the identification of the blazar TXS 0506+056 as the first promising high-energy neutrino counterpart candidate, we search for additional neutrino blazar candidates among the Fermi-Large Area Telescope detected ...
    • The first andean compressive tectonic phase: sedimentologic and structural analysis of mid-cretaceous ... 
      Boyce Marto, Daniel; Charrier González, Reynaldo; Farías Thiers, Marcelo (AGU, 2020)
      We document the effects of major mid-Cretaceous to Late Cretaceous compression within the volcanic arc of the western Gondwanan margin. The thinned Early Cretaceous Andean margin underwent rapid thickening and shortening-related ...
    • Encouraging pro-environmental behaviour through green identity labelling 
      Schwartz Perlroth, Daniel; Loewenstein, George; Aguero Gaete, Loreto (Nature, 2020)
      Promoting products for 'green' people has become an important strategy to encourage sustainable consumption. We test the effectiveness of the green identity labelling technique, which encourages pro-environmental purchases ...
    • Numerical study on cyclic response of end-plate biaxial moment connection in box columns 
      Gallegos, Marco; Núñez, Eduardo; Herrera Mardones, Ricardo (MDPI, 2020)
      The 2008 Wenchuan-China earthquake showed the importance of considering the bidirectional seismic action as a cause of failure in column hinge mechanisms. Subsequently, the large 2011 Tohoku-Japan earthquake revealed that ...
    • Modelling spatial patterns of near-surface air temperature over a decade of melt seasons on McCall Glacier, Alaska 
      Troxler, Patrick; Ayala, Álvaro; Francis Shaw, Thomas E.; Nolan, Matt; Brock, Ben W.; Pellicciotti, Francesca (Cambridge Univ Press, 2020)
      We examine the spatial patterns of near-surface air temperature (T-a) over a melting glacier using a multi-annual dataset from McCall Glacier, Alaska. The dataset consists of a 10-year (2005-2014) meteorological record ...
    • Flexural electromechanical properties of multilayer graphene sheet/carbon nanotube/vinyl ester hybrid ... 
      Sierra Chi, Carlos A.; Aguilar Bolados, Héctor; López Manchado, M. A.; Verdejo, R.; Cauich Rodríguez, Juan Valerio; Aviles, F. (Elsevier, 2020)

    • Fast and compact planar embeddings 
      Ferres, Leo; Fuentes Sepúlveda, José; Gagie, Travis; He, Meng; Navarro, Gonzalo (Elsevier, 2020)
      There are many representations of planar graphs, but few are as elegant as Turan's (1984): it is simple and practical, uses only 4 bits per edge, can handle self-loops and multiedges, and can store any specified embedding. ...
    • Existence of omega-periodic solutions for a delayed chemostat with periodic inputs 
      Amster, Pablo; Robledo Veloso, Gonzálo; Sepúlveda, Daniel (Elsevier, 2020)
      This paper proposes an omega-periodic version of the Ellermeyer model of delayed chemostat. We obtain a sufficient condition ensuring the existence of a positive omega-periodic solution. Our proof is based on the application ...
    • Entanglement entropy and the large N expansion of two-dimensional Yang-Mills theory 
      Donnelly, William; Timmerman, Sydney; Valdés Meller, Nicolás (Springer, 2020)
      Two-dimensional Yang-Mills theory is a useful model of an exactly solvable gauge theory with a string theory dual at large N. We calculate entanglement entropy in the 1/N expansion by mapping the theory to a system of N ...
    • Vagueness in multidimensional proposals 
      Zhang, Qiaoxi (Elsevier, 2020)
      This paper studies how agents choose to be vague in their proposals in a delegation environment. Two agents compete for the approval of a decision maker to implement a multidimensional action. Based on their knowledge of ...

    • Trends and emissions of six perfluorocarbons in the Northern Hemisphere and Southern Hemisphere 
      Droste, Elise S.; Adcock, Karina E.; Ashfold, Matthew J.; Chou, Charles; Fleming, Zoë; Fraser, Paul J.; Gooch, Lauren J.; Hind, Andrew J.; Langenfelds, Ray L.; Leedham Elvidge, Emma; Mohd Hanif, Norfazrin; O’Doherty, Simon; Oram, David E.; Ou Yang, Chang Feng; Panagi, Marios; Reeves, Claire E.; Sturges, William T.; Laube, Johannes C. (Copernicus Gesellschaft, 2020)
      Perfluorocarbons (PFCs) are potent greenhouse gases with global warming potentials up to several thousand times greater than CO2 on a 100-year time horizon. The lack of any significant sinks for PFCs means that they have ...
