(Canadian Mathematical Society, 2015)We prove that quasiconvex functions always admit descent trajec- tories bypassing all non-minimizing critical points.
-
(ELSEVIER SCIENCE, 2003-11-15)We consider a discrete-time ergodic Markov chain on a partially ordered state space and study the stochastic comparison between its invariant measure and some measures related with the behaviour of the chain conditioned ...
-
(Tech Univ Braunschweig, 2016)Our goal is to show that the standard model-theoretic concept of types can be applied in the study of order-invariant properties, i.e., properties definable in a logic in the presence of an auxiliary order relation, hut ...
-
(Public Library Science, 2020)In sequential competitions, the order in which teams take turns may have an impact on performance and the outcome. Previous studies with penalty shootouts have shown mixed evidence of a possible advantage for the first ...
-
(ELSEVIER, 2006-05)This paper addresses the problem of assessing the risk of deficiency or excess of a soil property at unsampled locations, and more generally of estimating a function of such a property given the information monitored at ...
-
(Springer, 2020)Grade control and short-term planning determine the performance of a mining project. Improving this decision, by collecting the most informative samples (data) may have significant financial impact on the project. In this ...
-
(Elsevier, 2019)We have investigated how biota contributes to rapid chemical weathering of Hawaiian basalts using a reactive transport model and chemical data from a soil chronosequence. These Hawaiian soils have developed under a tropical ...
-
(ELSEVIER SCIENCE INC, 2016)In the literature on organizational learning, very few empirical studies attempt to show how organizational design can enable or hinder learning in organizations. This study uses a fuzzy-set technique (fuzzy-set qualitative ...
-
(Springer, 2013)Tupungatito is a poorly known volcano located about 100 km eastward of Santiago (Chile) in the northernmost sector of the South Volcanic Zone. This 5,682 m high volcano shows intense fumarolic activity. It hosts three ...
-
(Elsevier, 2018-05-15)The Quetrupillan Volcanic Complex (QVC) is a stratovolcano placed in the center of a NW-SE volcanic chain, between Villarrica volcano and Lanin volcano, in the Central Southern Volcanic Zone of the Andes. Its youngest ...
-
(Oxford University Press, 2015)In order to elucidate the origin of spin in both dark matter and baryons in galaxies, we have performed hydrodynamical simulations from cosmological initial conditions. We study atomic cooling haloes in the redshift range ...
-
(IOP Publishing, 2020)We study the structure of multi-field inflation models where the primordial curvature perturbation is able to vigorously interact with an ultra-light isocurvature field - a massless fluctuation orthogonal to the background ...
-
(1989-03-01)The most powerful water maser feature ever seen in Orion was monitored for seven years. The maser reached a peak flux density of about 6.7 x 10 to the 6th Jy. The total radiated energy between August 1979 and June 1987 was ...
-
(ELSEVIER SCIENCE BV, 2016)The stratigraphy of the Bahia Inglesa Formation in the Caldera Basin west of Copiapo, (north-central Chile) is revised, based on hitherto unpublished stratigraphic sections and Sr-87/Sr-86 dating. The depositional environment ...
-
(AGU, 2015)The orographic effect of the Andes (30 degrees S-55 degrees S) on upwind precipitating clouds from midlatitude frontal systems is investigated using surface and satellite data. Rain gauges between 33 degrees S and 44 degrees ...
-
(AMER METEOROLOGICAL SOC, 2016)The Nahuelbuta Mountains (NM) are a semielliptical massif 1300 m high in coastal southern Chile (37 degrees-38 degrees S) facing frontal storms that move from the Pacific. Mean precipitation between 900 and 1200 mm yr(-1) ...
-
(ELSEVIER, 2005-01-17)In this paper, we present the synthesis and characterization of new orthopalladated complexes derived from alpha-diphenylhydrazonoketene dithioacetals. From their reaction with terminal alkynes, the intermediates of the ...
-
(Amer Physical SOC, 2018)Macroscopic systems forced by the temporal modulation of their parameters exhibit complex interfaces between symmetric states. Here we investigate the origin of the transition from a flat to an oscillating decorated ...
-
(Elsevier, 2017)The purpose of this paper is to assess the use of multi-elemental otolith fingerprints as a tool to delimit catfish Genidens barbus fish stocks in four estuaries from the southwestern Atlantic Ocean. Barium:Calcium (Ca), ...
-
(Elsevier, 2015)The Maule 2010 megathrust earthquake M-w 8.8 has been characterized by two coseismic high-slip patches (asperities) north and south of the epicenter, separated by a region of lower slip. Here, we invert full broadband ...
