One-relator groups and proper 3-realizability
(European Mathematical Society, 2009)
How different is the universal cover of a given finite 2-complex from a 3-manifold (from the proper homotopy viewpoint)? Regarding this question, we recall that a finitely presented group G is said to be properly 3-realizable ...

Optimization methods for the planning of rapid transit systems
(Elsevier, 2000)
A central question when planning rapid transit systems is the determination of alignments and stations. Operational research methods can help solve these problems and they are also useful for the assessment of the network ...

La crisis de identidad del periodista y la ética profesional
(Universidad Complutense, 2009)
La crisis de una ética profesional del periodismo es una de las raíces de los males endémicos del periodismo en nuestro país. El perjuicio no supone sólo una merma en la credibilidad del periodismo, sino también una ...

Noncovalent interactions of tiopronin-protected gold nanoparticles with DNA: two methods to quantify free energy of binding
(2014)
The binding of gold nanoparticles capped with N-(2-mercaptopropionyl)glycine (Au@tiopronin) with double-stranded DNA has been investigated and quantified in terms of free energies by using two different approaches. The ...

Stochastic resonance with weak monochromatic driving: Gains above unity induced by high-frequency signals
(European Physical Society, 2007)
We study the effects of a high-frequency (HF) signal on the response of a noisy bistable system to a low-frequency subthreshold sinusoidal signal. We show that, by conveniently choosing the ratio of the amplitude of the ...

Feeding Software Agents with Web Information
(Springer, 2015)
Many software agents require information that is available in web documents. Unfortunately, the existing proposals to learn extrac tion rules are tightly coupled with the learning component and do not result in resilient ...

Deformation mechanisms in yttria-stabilized cubic zirconia single crystals
(Walter de Gruyter, 2010)
This work attempts to give a unified picture of the microscopic mechanisms which control the plastic deformation in yttria-stabilized cubic zirconia single crystals, particularly for the soft orientation (uniaxial compression ...

Optimal design under the one-dimensional wave equation
(European Mathematical Society, 2008)
An optimal design problem governed by the wave equation is examined in detail. Specifically, we seek the time-dependent optimal layout of two isotropic materials on a 1-d domain by minimizing a functional depending ...

Application of Internode model to global power consumption estimation in SCMOS gates
(Springer, 2005)
In this paper, we present a model, Internode, that unifies the gate functional behavior and the dynamic one. It is based on a FSM that represents the internal state of the gate depending on the electrical load of its ...
