(Springer, 2017)Our interdisciplinary research is dedicated to exploring the boundaries of stereoscopic filmmaking from an unusual viewpoint: we aim at creating 3D non-photorealistic cinema which allows conciliating a stereoscopic ...
-
(Pontificia Universidad Catolica de Chile, 2019)This study was aimed at analyzing, based on the participating teachers' emotional experience, the meanings constructed by them regarding the task of responding to diversity. To do this, the researchers analyzed 12 interviews ...
-
(Elsevier, 2015)The stability of a circular localized spot with respect to azimuthal perturbations is studied in a prototype variational model, namely, a Swift-Hohenberg type equation. The conditions under which the circular shape of the ...
-
(Elsevier B.V., 2019)© 2018 Elsevier B.V.In this work we prove that designing PPMs is equivalent to finding stopping rules for prophets. This extends the connection that any prophet type inequality can be turned into a PPM with the same ...
-
(Elsevier, 2018-08)The compartmentalization of C-4 plants increases photosynthetic efficiency, while constraining how material and energy must flow in leaf tissues. To capture this metabolic phenomenon, a generic plant metabolic reconstruction ...

(Elsevier, 2018-04-20)In this paper, we present recent data on Early Holocene human occupations from Taltal, in the coast of the Atacama Desert. We focus on evidences of mobility and subsistence economy, discussing the data in terms of a concept ...
-
(American Physical Society, 2019)Driven dissipative many-body systems are described by differential equations for macroscopic variables which include fluctuations that account for ignored microscopic variables. Here, we investigate the effect of deterministic ...
-
(Taylor and Francis Ltd., 2018)A simple model for the front of unimpeded infiltrated sand, moving as sediment transport through immobile coarse gravel particles is proposed. The theoretical celerity of the front computed by the model matched the celerity ...
-
(American Physical Society, 2018)Spatially forced systems can exhibit coexistence and a rich interface dynamics between manipulable states. We show here how the propagation speed of a front into an unstable state can be modified through periodic space ...
-
(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 ...
-
(AMERICAN PHYSICAL SOC, 2006-07)The effect of noise in a motionless front between a periodic spatial state and an homogeneous one is studied. Numerical simulations show that noise induces front propagation. From the subcritical Swift-Hohenberg equation ...
-
(OSA - The Optical Society, 2019)Driven optical systems can exhibit coexistence of equilibrium states. Traveling waves or fronts between different states present complex spatiotemporal dynamics. We investigate the mechanisms that govern the front spread. ...
-
(Frontiers Media S.A., 2019)In humans and non-humans primates, extensive evidence supports the existence of subcortico-cortical circuits for cognition and behavior. Lesions studies are critical to understand the clinical significance of these ...
-
(ELSEVIER, 2004-12-01)We show that in a liquid-crystal-light-valve with optical feedback the Freedericksz transition displays a subcritical character. Experimentally, we determine the extension of the bistable region and we study the propagation ...
-
(Universidad de Chile, 2015)El Desierto de Atacama, ubicado en el norte de Chile corresponde al desierto más árido del planeta. En esta región se encuentran las mayores reservas de yodo a nivel mundial y a su vez corresponde a la principal provincia ...
-
(MDPI, 2018)A fully adaptive particle filtering algorithm is proposed in this paper which is capable of updating both state process models and measurement models separately and simultaneously. The approach is a significant step toward ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-12)A fully coupled "online" Weather Research and Forecasting/Chemistry (WRF/Chem) model has been developed. The air quality component of the model is fully consistent with the meteorological component; both components use the ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2011-06)Metric access methods based on hyperplane partitioning have the advantage, compared to the ball partitioning-based ones, that regions do not overlap. The price is less flexibility for controlling the tree shape, especially ...
-
(ACM, 2014)We propose new succinct representations of ordinal trees and match various space/time lower bounds. It is known that any n-node static tree can be represented in 2n + o(n) bits so that a number of operations on the tree ...
