(Hindawi Publishing Corp., 2016)Piezoelectric cantilevered beams have been widely used as vibration-based energy harvesters. Nevertheless, these devices have a narrow frequency band and if the excitation is slightly different there is a significant drop ...
-
(Royal Soc Chemistry, 2021)We present a new heteroditopic ligand (3pyCCMoid) that contains the typical skeleton of a curcuminoid (CCMoid) decorated with two 3-pyridyl groups. The coordination of 3pyCCMoid with ZnII centres results in a set of novel ...

(2005)A de Bruijn sequence over a finite alphabet of span n is a cyclic string such that all words of length n appear exactly once as factors of this sequence. We extend this definition to a subset of words of length n, ...

(SCUOLA NORMALE SUPERIORE, 2016)We consider the problem {-Delta u + u = u(p) + lambda u(q) u > 0 in R-Nu(z) -> 0 as vertical bar z vertical bar -> infinity where p = p* + epsilon, with p* = N+2/N-2, while 1 < q < N+2/N-2 if N >= 4, and 3 < q < 5 if N = ...

(PERGAMON-ELSEVIER SCIENCE LTD, 2008-03-01)In this work we consider the following problem [GRAPHICS] with N/(N - 2) < p < p* = (N + 2)/(N - 2) < q, N >= 3. We prove that if p is fixed, and q is close enough to the critical exponent p*, then there exists a ...
-
(2000-10-30)We study the dynamics of bubbles in the one dimensional Cahn-Hilliard equation. For a gas of diluted bubbles we find ordinary differential equations describing their interaction which permits us to describe the ulterior ...
-
(European Mathematical Society Publishing House, 2017)We investigate bubbling solutions for the nonlocal equation Aω s u = up, u > 0 in ω, under homogeneous Dirichlet conditions, where ω is a bounded and smooth domain. The operator As ω stands for two types of nonlocal ...
-
(Elsevier, 2015)Let (M, g) be an n-dimensional compact Riemannian manifold without boundary and Gamma be a non-degenerate closed geodesic of (M, g). We prove that the supercritical problem -Delta(g)u + hu = u(n+1/n+3) (+/-) (epsilon), ...
-
(Oxford Univ Press, 2016)In a hierarchical Universe clusters grow via the accretion of galaxies from the field, groups and even other clusters. As this happens, galaxies can lose and/or consume their gas reservoirs via different mechanisms, ...

(Universidad de Chile, 2010)Este estudio analiza el rol de la gestión en educación municipal en Chile y en algunas de sus comunas, y pretende contribuir a mejorar la calidad de su oferta pública en educación primaria y secundaria. En la primera ...
-
(Universidad de Chile, 2017)Una de las tareas de la Administración Pública es la satisfacción de la necesidades colectivas, para ello en Chile se han aprobado una serie de dispositivos legales, tales como el Código Buenas Prácticas en Probidad, Ética, ...

(Universidad de Chile, 2017)Chile se encuentra actualmente en un proceso de cambios en su regulación bancaria, mediante un proyecto que tiene como fin modificar la Ley General de Bancos (LGB), y así aumentar la solidez del sistema financiero del ...
-
(Springer Science and Business Media Deutschland GmbH, 2019)© 2018, The Author(s).Studies examining urban health and the environment must ensure comparability of measures across cities and countries. We describe a data platform and process that integrates health outcomes together ...
-
(Routledge, 2016)We analyse how to deal with the uncertainty before solving a stochastic optimization problem and we apply it to a forestry management problem. In particular, we start from historical data to build a stochastic process for ...
-
(IEEE, 2017)The Domain Name System (DNS) has evolved to support the exponential growth of the Internet, by relying heavily on a highly distributed infrastructure. Nevertheless, trust between server must exist in order to guarantee ...
-
(John Wiley and Sons Ltd, 2019)In this work, the adsorption of a type of cruciform system integrated by an anthracene central part and two side chains with a pyridine-vinyl structure (DPAC) was studied on plasmonic nanoparticles of silver and gold. The ...
-
(Elsevier, 2016)We research the problem of building knowledge maps of graph-like information. There exist well-consolidated cartographic principles and techniques for mapping physical landscapes. However, we live in the digital era and ...
-
(Springer, 2017)We present a decision support system to help plan preventive border patrols. The system represents the interaction between defenders and intruders as a Stackelberg security game (SSG) where the defender pools local resources ...
