(The American Astronomical Society, 2010-09-28)We present Gemini-North K-band spectra of two representative members of the class of high-redshift quasars with exceptionally weak rest-frame ultraviolet emission lines (WLQs), SDSS J114153.34+021924.3 at z = 3.55 and SDSS ...

Weak signal enhancement by nonlinear resonance control in a forced nano-electromechanical resonator (Nature, 2020)Driven non-linear resonators can display sharp resonances or even multistable behaviours amenable to induce strong enhancements of weak signals. Such enhancements can make use of the phenomenon of vibrational resonance, ...

(Elsevier, 2018)In this paper, we study the elliptic problem with Dirac mass { -Delta u = Vu(p) + k delta(0) in R-N, (1) lim(vertical bar x vertical bar ->+infinity) u(x) = 0, where N > 2, p > 0, k > 0, delta(0) is the Dirac ...

(Wiley-V C H Verlag GMBH, 2016)In this paper we prove the existence of weak solutions for the inclusion problem in anti-plane Cosserat elasticity in Sobolev space setting, and for the corresponding systems of boundary integral equations.
-
(AMERICAN PHYSICAL SOC, 2006-07-14)We study the long-time evolution of waves of a thin elastic plate in the limit of small deformation so that modes of oscillations interact weakly. According to the theory of weak turbulence (successfully applied in the ...
-
(UNIV CHICAGO PRESS, 2004-09-20)We use the weak gravitational lensing effect to study the mass distribution and dynamical state of a sample of 24 X-ray-luminous clusters of galaxies (0.05 < z < 0.31) observed with the FORS1 instrument mounted on the ...
-
(Wiley, 2018-06)This paper presents an approach to generalize the concept of isogeometric analysis by allowing different spaces for the parameterization of the computational domain and for the approximation of the solution field. The ...
-
(Elsevier, 2016)In this paper we establish new rules for the calculus of the subdifferential mapping of the sum of two convex functions. Our results are established under conditions which are at an intermediate level of generality among ...
-
(Association for Computing Machinery, 2018)This article presents a wp–style calculus for obtaining bounds on the expected runtime of randomized algorithms. Its application includes determining the (possibly infinite) expected termination time of a randomized algorithm ...
-
(Frontiers Media S.A., 2019)Co-expression analysis has been widely used to elucidate the functional architecture of genes under different biological processes. Such analysis, however, requires substantial knowledge about programming languages and/or ...

(Elsevier, 2018-08)A graph G = (V, E) is weighted-k-antimagic if for each w : V -> R, there is an injective function f : E -> {1,...,vertical bar E vertical bar + k} such that the following sums are all distinct: for each vertex u, Sigma(v:uv ...
-
(2007)Geostatistical estimation and simulation techniques are useful for characterizing the spatial distribution of soil properties. These techniques usually rely on a variogram model that measures the spatial variability of the ...
-
(Royal Soc., 2015)Many complex systems can be described as networks exhibiting inner organization as communities of nodes. The identification of communities is a key factor to understand community-based functionality. We propose a family ...
-
(Frontiers Media, 2022)The COVID-19 pandemic continues to impact schools and how education is conveyed to students. One of the aspects that has gained strength is supporting the wellbeing of educational communities. The purpose of this study was ...
-
(JOHN WILEY, 2006-03-25)In this paper we study the Navier-Stokes boundary-initial value problem in the exterior of a rotating obstacle, in two and three spatial dimensions. We prove the local in time existence and uniqueness of strong solutions. ...

(American Physical Society, 2017)A lattice model for active matter is studied numerically, showing that it displays wetting transitions between three distinctive phases when in contact with an impenetrable wall. The particles in the model move persistently, ...

(IEEE, 2017)For the last ten years we have been teaching acapstone course for fifth year students of the Computer ScienceDepartment of the Universidad de Chile. Five year ago weredesigned the course, shifting from ...

(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2003-10)There is considerable heterogeneity in the development of derivatives markets in different countries. The question is: why? This paper addresses this question in the context of major derivatives markets in Latin America. ...
