Asymptotic normality for the counting process of weak records and delta-records in discrete models (2007)Let {X-n, n >= 1} be a sequence of independent and identically distributed random variables, taking non-negative integer values, and call X-n a delta-record if X-n > max{X-1,..., Xn-1} + delta, where delta is an integer ...

(CAMBRIDGE UNIV PRESS, 2006-08)Let M = N-D be the positive orthant of a D-dimensional lattice and let (G, +) be a finite abelian group. Let G subset of G(M) be a subgroup shift, and let mu be a Markov random field whose support is G. Let Phi : G -> G ...

(SPRINGER, 2008-06)We consider the asymptotic behavior of the solution of one dimensional stochastic differential equations and Langevin equations in periodic backgrounds with zero average. We prove that in several such models, there is ...

(NATURE PUBLISHING GROUP, 2003-08-07)Stars that explode as supernovae come in two main classes. A type Ia supernova is recognized by the absence of hydrogen and the presence of elements such as silicon and sulphur in its spectrum; this class of supernova is ...

(Association for Computing Machinery, 2017)Given an array A[1, n] of elements with a total order, we consider the problem of building a data structure that solves two queries: (a) selection queries receive a range [i, j] and an integer k and return the position of ...

(PERGAMON-ELSEVIER SCIENCE LTD, 2008-09-01)Let 1 < p < N, and u be a nonnegative solution of -Delta(p)u = f (x, u) on R-N\(B-1) over bar where f behaves like \x\(-l)u(q) near \x\ = infinity and u = 0, for some constants q >= 0 and l is an element of R. We obtain ...

Asymptotics for eigenvalues of the Laplacian in higher dimensional periodically perforated domains (2010)This paper considers the periodic spectral problem associated with the Laplace operator written in RN (N = 3, 4, 5) periodically perforated by balls, and with homogeneous Dirichlet condition on the boundary of holes. We ...
-
(Elsevier, 2016)A multicone domain Omega subset of R-n is an open, connected set that resembles a finite collection of cones far away from the origin. We study the rate of decay in time of the heat kernel p(t, x, y) of a Brownian motion ...
-
(Springer, 2019)Sorbitol is synthesized in Rosaceae species, especially in source organs, in a pathway involving aldose 6-phosphate reductase (A6PR, EC 1.1.1.200). As compatible solutes, sorbitol and other sugar alcohols assist in the ...
-
(Springer, 2020)The Atacama Desert is one of the oldest and driest places on Earth. In the last decade, microbial richness and diversity has been acknowledged as an important biological resource of this region. Owing to the value of the ...
-
(Taylor and Francis Ltd., 2019)This work presents the preliminary results of the first field calibration campaign performed in the Atacama Desert, Chile, between the 18 and 22 August 2014, called the Atacama Field Campaign (ATAFIC 2014). In situ ...

(SPRINGER, 2008-08)The presence of large amounts of atacamite in oxide zones from ore deposits in the Atacama Desert of northern Chile requires saline solutions for its formation and hyperarid climate conditions for its preservation. We ...
-
(2007)Atacamite, a copper hydroxychloride, is an important constituent of supergene oxide zones of copper deposits in northern Chile, whereas in similar deposits elsewhere, it is rare. In Chile, it has generally been assumed to ...
-
(Royal Astronomical Society, 2015)We present a 30–50 GHz survey of Sagittarius B2(N) conducted with the Australia Telescope Compact Array with ∼5–10 arcsec resolution. This work releases the survey data and demonstrates the utility of scripts that perform ...

(EDP Sciences, 2012-10-24)Context. The APEX Telescope Large Area Survey of the GALaxy (ATLASGAL) is the first systematic survey of the inner Galactic plane in the sub-millimetre. The observations were carried out with the Large APEX Bolometer Camera ...

(EDP Sciences, 2014)Context. The APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) is the largest and most sensitive systematic survey of the inner Galactic plane in the submillimetre wavelength regime. The observations were carried ...

(Oxford University Press on behalf of the Royal Astronomical Society, 2013-03-12)Using the 870 mu m APEX Telescope large area survey of the Galaxy, we have identified 577 submillimetre continuum sources with masers from the methanol multibeam survey in the region 280 degrees < l < 20 degrees; vertical ...
