(Universidad de Chile, 2009)Esta tesis consta de dos artículos en Teoría de Contratos. El primero es un análisis teórico de las consecuencias de suponer un agente con preferencias aversas a las pérdidas en un modelo de riesgo moral dinámico, usando ...
-
(Oxford University, 2017)Multiple populations revealed in globular clusters (GCs) are important windows to the forma-tion and evolution of these stellar systems. The metal-rich GCs in the Galactic bulge are anindispensable part of this picture, ...

(2002-11-10)We report sensitive Australia Telescope Compact Array radio continuum observations toward IRAS 15596 5301 and 16272 4837, two luminous objects (L > 2 104 L ) thought to represent massive starforming regions in early ...
-
(Oxford University Press, 2013)We have used the Two-Micron All-Sky Survey and the Wide-field Infrared Survey Explorer to look for ultracool dwarfs that are part of multiple systems containing main-sequence stars.We cross-matched L dwarf candidates ...
-
(BLACKWELL, 2006-02)The structures of the two title isomeric compounds, [Zn(C5H7O2)(2)(C12H10N4)](n), are built up around two non-equivalent symmetry centres, one of them at the cation position and the other bisecting the N-N bond in the ...
-
(Universidad de Chile, 2014)En este trabajo se aborda el problema de encontrar soluciones regulares para algunas EDPs elípticas e hipo-elípticas no lineales y estudiar sus propiedades cualitativas. En una primera etapa, se considera la ecuación $$ -\Delta ...
-
Two studies on the interplay between topological phases, robust edge states and bosonic excitations (Universidad de Chile, 2021)Esta tesis está compuesta por dos partes. En la parte I estudiamos el rol de la topología en la propagación de luz cuántica por una red fotónica con orden topológico no trivial. Nos enfocamos en el comportamiento de estados ...
-
(IOP, 2021)The Cosmology Large Angular Scale Surveyor (CLASS) is a four-telescope array observing the largest angular scales (2 ℓ 200) of the cosmic microwave background (CMB) polarization. These scales encode information ...
-
(SPRINGER/PLENUM PUBLISHERS, 2008-04)Three new coordination complexes of Zn(II) and Mn(II) have been synthesised using two different tridentate N,N,O donor hydrazone ligands, Hpbh and Hacpbh respectively. The complexes [Zn(pbh)2] (1) and [Zn (acpbh)2] (2) ...
-
(Institute of Electrical and Electronics Engineers Inc., 2018)The Block Tree (BT) is a novel compact data structure designed to compress sequence collections. It obtains compression ratios close to Lempel-Ziv and supports efficient direct access to any substring. The BT divides the ...
-
(2009)Term-partitioned indexes are generally inefficient for the evaluation of conjunctive queries, as they require the communication of long posting lists. On the other side, document-partitioned indexes incur in excessive ...
-
(ELSEVIER, 2003-10)A two-dimensional dynamic model for bioleaching of secondary copper minerals from a pile has been developed. In the model. aeration of the pile is considered to be due to natural convection caused by the density gradient ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-12-01)We consider the problem of Ambrosetti-Prodi type [GRAPHICS] where Q is a bounded, smooth domain in R-2, phi(1) is a positive first eigenfunction of the Laplacian under Dirichlet boundary conditions and h is an element ...
-
(2006-07-15)We consider the two-dimensional motion of a rigid structure immersed in an incompressible fluid governed by Navier-Stokes equations. The control force acts on a fixed subset of the fluid domain. We prove that our system ...

Two-dimensional nanomaterials for the removal of pharmaceuticals from wastewater: a critical review (MDPI, 2021)The removal of pharmaceuticals from wastewater is critical due to their considerable risk on ecosystems and human health. Additionally, they are resistant to conventional chemical and biological remediation methods. ...
