Homogenization of Mutually Immiscible Polymers Using Nanoscale Effects: A Theoretical Study
(Hindawi Publishing Corporation, 2008)
A theoretical study to investigate homogenization of mutually immiscible polymers using nanoscale effects has been performed. Specifically, the miscibility behavior of all-polymer nanocomposites composed of linear-polystyrene ...
First-principles calculations of hot-electron lifetimes in metals
(American Physical Society, 2000)
First-principles calculations' of the inelastic lifetime of low-energy electrons in Al, Mg, Be, and Cu are reported. Quasiparticle damping rates are evaluated from the: knowledge of the electron self-energy, which we compute ...
Role of occupied d bands in the dynamics of excited electrons and holes in Ag
(American Physical Society, 2003)
The role that occupied d bands play in the inelastic lifetime of bulk and surface states in Ag is investigated from the knowledge of the quasiparticle self-energy. In the case of bulk electrons, sp bands are taken to be ...
Position-dependent exact-exchange energy for slabs and semi-infinite jellium
(American Physical Society, 2009-12)
The position-dependent exact-exchange energy per particle epsilon(x)(z) (defined as the interaction between a given electron at z and its exact-exchange hole) at metal surfaces is investigated, by using either jellium slabs ...
Exchange-Correlation Hole of a Generalized Gradient Approximation for Solids and Surfaces
(American Physical Society, 2009-02)
We propose a generalized gradient approximation (GGA) for the angle- and system-averaged exchange-correlation hole of a many-electron system. This hole, which satisfies known exact constraints, recovers the Perdew-Burke-Ernzerhof ...
The Weekend-Dividend Effect in the Spanish Market
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2002-06)
In this paper we develop an econometric test of a corollary of the irrelevance of the dividend policy principle, namely, that the rescheduling of dividends does not affect the market valuation of the firm. In particular, ...
Mapping the nation in contemporary Basque literature
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2008)
This article examines the importance of memory and reflections on memory in the modern humanities. After a brief review of the concepts introduced by various critics and historians (Muller, White, Hutcheon, Lowenthal, ...
Basque writing in the Iberian context: brief notes on the translations of Basque literature
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2009)
After considering the function of translated literature (from Basque, into Basque) in our literary system, the article analyzes the relations between the literatures of Spain (Catalan, Galician and Spanish). Some reflections ...
A multi-gene analysis strategy identifies metabolic pathways targeted by trans-10, cis-12-conjugated linoleic acid in the liver of hamsters
(Cambridge University Press, 2009-08-28)
In mice, hepatic functions can be greatly affected by dietary trans-10, cis-12-conjugated linoleic acid (CLA). However, this phenomenon has been less documented in hamsters. In the present study, male hamsters were fed two ...
Absorbing Sets in Coalitional Systems
(2001-12)
The purpose of this paper is twofold: First, to present an approach and a solution for analyzing the stability of coalition structures: We define a coalitional system (a set and a binary relation on that set) that explains ...
