(American Geophysical Union, 2017)Small-scale heterogeneity of permeability controls spreading, dilution, and mixing of solute plumes at large scale. However, conventional numerical simulations of solute transport are unable to resolve scales of heterogeneity ...
-
(Springer, 2015)Lahars are catastrophic events that have the potential to cause the loss of life and damage to infrastructure over inhabited areas. Consequently the zoning of associated hazards is a critical task. We evaluated the lahar ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-10)Sedimentological studies including X-ray digital analyses, mineralogy, inorganic contents, and organic geochemistry on cores of laminated sediments accumulated in the oxygen minimum zone of the central Peruvian margin ...
-
(Elsevier, 2017)Today we have the opportunity without precedents to analyze human land use or mobility behavior in a city, country or even the globe. Some studies have analyzed existing data generated daily by mobile networks, mostly using ...
-
(American Physical Society, 2019)We show that the dynamics of a driven quantum system weakly coupled to a finite reservoir can be approximated by a sequence of Landau-Zener transitions if the level spacing of the reservoir is large enough. This approximation ...
-
(MDPI, 2020)Understanding of people's landscape preferences is important for decision-making about land planning, particularly in the disturbance patterns that usually occur in rural-urban gradients. However, the use of different types ...
-
(Springer Netherlands, 2020)Guidance for large-scale restoration of natural or semi-natural linear vegetation elements that takes into account the need to maintain human livelihoods such as farming is often lacking. Focusing on a Chilean biodiversity ...
-
(American Physical Society, 2018)In this paper, we show how the structure of the landscape potential of the primordial Universe may be probed through the properties of the primordial density perturbations responsible for the origin of the cosmic microwave ...
-
(Springer Verlag, 2019)The 2010 Mw = 8.8 Maule earthquake, which occurred in the subduction contact between the Nazca and the South American tectonic plates off the coast of Chile, represents an important opportunity to improve understanding of ...

(Elsevier, 2013)The problems of composing and inverting schema mappings specified by source-to-target tuple-generating dependencies (st-tgds) have attracted a lot of attention, as they are of fundamental importance for the development ...
-
(Springer, 2015)Let (M, g) be a two dimensional compact Riemannian manifold of genus g(M) > . Let f be a smooth function on M such that f >= 0, f not equivalent to 0, min(M) f = 0. Let be any set of points at which f (P-i) = 0 and ...
-
(2007)In this paper we investigate the critical exponents of two families of Pucci's extremal operators. The notion of critical exponent that we have chosen for these fully nonlinear operators which are not variational is that ...
-
(Frontiers Media, 2016)The high Andean plateau or Altiplano contains different waterbodies that are subjected to extreme fluctuations in abiotic conditions on a daily and an annual scale. The bacterial diversity and community composition of those ...
-
(WILEY-BLACKWELL, 2012-03)The Mw 8.8 Maule earthquake occurred off the coast of central Chile on 2010 February 27 and was the sixth largest earthquake to be recorded instrumentally. This subduction zone event was followed by thousands of aftershocks ...
-
(Academic Press Inc Elsevier Science, 2016)We consider the boundary value problem { -Delta u + u = lambda e(u), in Omega partial derivative(v)u = 0 on partial derivative Omega where Omega is a bounded smooth domain in R-2, lambda > 0 and v is the inner ...
-
(2006-02-20)Using high angular resolution ( 0B25–0B05) Very Large Array (VLA) observations made at 3.6 cm, 1.3 cm, and 7 mm during the period 1991–2004, we report the detection of large proper motions in the components of the ...
-
(UNIV CHICAGO PRESS, 1989-11-15)The triple radio source in the Serpens star formation region consists of a central object and two lobes with spectral indices characteristic of nonthermal emission. Measurements made at the Arecibo Observatory and the VLA ...
-
(IOP Publishing Ltd, 2017)We report the first map of large-scale (10 pc in length) emission of millimeter-wavelength hydrogen recombination lines (mm-RRLs) toward the giant H II region around the W43-Main young massive star cluster (YMC). Our mm-RRL ...
