Single-parameter spin-pumping in driven metallic rings with spin-orbit coupling
(2014)
We consider the generation of a pure spin-current at zero bias voltage with a single time-dependent potential. To such end we study a device made of a mesoscopic ring connected to electrodes and clarify the interplay between ...
Multi-characterization of electron-induced defects in highly oriented pyrolytic graphite
(2016)
Engineering the properties of materials through defects is at the forefront of research in Materials Science. Here, we investigate the defects produced on highly oriented pyrolytic graphite (HOPG) samples irradiated with ...
Axiomatizing bisimulation equivalences and metrics from probabilistic SOS rules
(2014)
Probabilistic transition system specifications (PTSS) provide structural operational semantics for reactive probabilistic labeled transition systems. Bisimulation equivalences and bisimulation metrics are fundamental notions ...
Improved upper limits on the stochastic gravitational-wave background from 2009-2010 LIGO and Virgo data
(2014)
Gravitational waves from a variety of sources are predicted to superpose to create a stochastic
background. This background is expected to contain unique information from throughout the history of
the Universe that is ...
Modeling spatial patterns in the visual cortex
(2014)
We propose a model for the formation of patterns in the visual cortex. The dynamical units of the model are Kuramoto phase oscillators that interact through a complex network structure embedded in two dimensions. In this ...
Magnetite NPs@C with highly-efficient peroxidase-like catalytic activity as an improved biosensing strategy for selective glucose detection
(2014)
This work reports the novel application of carbon-coated magnetite nanoparticles (mNPs@C) as catalytic nanomaterial included in a composite electrode material (mNPs@C/CPE) taking advantages of their intrinsic peroxidase-like ...
La actividad eléctrica atmosférica en Argentina : estimación de la tasa de mortalidad anual por acción de caídas de rayos
(2014)
Disponer de información de la actividad eléctrica en el territorio nacional es un elemento fundamental para la vigilancia atmosférica. Tanto para aplicaciones de relevancia, en cuestiones de seguridad e infraestructura, ...
Improving furosemide polymorphs properties through supramolecular complexes of beta-cyclodextrin
(2014)
In this work, complexes of β-cyclodextrin and the two solid forms of furosemide were prepared and characterized for their potential pharmaceutical applications, with the interactions between the two compounds being studied ...
Magnitude modelling of HRTF using principal component analysis applied to complex values
(2014)
Principal components analysis (PCA) is frequently used for modelling the magnitude of the head related transfer functions (HRTFs). Assuming that the HRTFs are minimum phase systems, the phase is obtained from the Hilbert ...
Pure type systems with explicit substitutions
(2015)
We introduce a new formulation of pure type systems (PTSs) with explicit substitution and
de Bruijn indices and formally prove some of its meta-theory. Using techniques based on
Normalisation by Evaluation, we prove that ...
