The effect of the electric wind on the spatial distribution of chemical species in the positive corona discharge
(IOP, 2017)
The electrohydrodynamic air flow generated by a positive corona discharge, and its effect on the spatial distribution of chemical species within a wire-plate corona reactor, have been numerically simulated. The computational ...

First absolute measurements of fast-ion losses in the ASDEX Upgrade tokamak
(Institute of Physics Publishing, 2017)
A new diagnostic technique that allows to obtain absolute fluxes of fast-ion losses measured with absolutely calibrated scintillator based fast-ion loss detectors (FILD) is presented here. First absolute fluxes of fast-ion ...

Characterisation of the intra-annual rainfall and its evolution (1837-2010) in the southwest of the Iberian Peninsula
(Springer Nature, 2013)
Variability in precipitation affects annual total records and causes instability in rainfall distribution throughout the year. Our aim in this study was to develop a procedure, based on pluviometric centralisation and ...

What causes the inverse relationship between primary production and export efficiency in the Southern Ocean?
(Wiley, 2016-05-07)
The ocean contributes to regulating atmospheric CO2 levels, partly via variability in the fraction of primary production (PP) which is exported out of the surface layer (i.e., theeratio). Southern Ocean studies have found ...

Loophole-free bell test based on local precertification of photon’s presence
(American Physical Society, 2012-06-11)
A loophole-free violation of Bell inequalities is of fundamental importance for demonstrating quantum nonlocality and long-distance device-independent secure communication. However, transmission losses represent a fundamental ...

Experimental fully contextual correlations
(American Physical Society, 2012)
Quantum correlations are contextual yet, in general, nothing prevents the existence of even more contextual correlations. We identify and test a noncontextuality inequality in which the quantum violation cannot be improved ...

Uranium in the surrounding of San Marcos-Sacramento river environment (Chihuahua,Mexico)
(2011-11)
The main interest of this study is to assess whether uranium deposits located in the San Marcos outcrops (NW of Chihuahua City,Mexico) could be considered as a source of U-isotopes in its surrounding environment. Uranium ...

Classical Physics and the Bounds of Quantum Correlations
(American Physical Society, 2016-06-24)
A unifying principle explaining the numerical bounds of quantum correlations remains elusive, despite the efforts devoted to identifying it. Here, we show that these bounds are indeed not exclusive to quantum theory: for ...

239PU, 240PU, and 241AM Determination in Hot Particles by Low Level Gamma-Spectrometry
(American Chemical Society, 2010)
A nondestructive method based on low-energy, highresolution photon spectrometry is presented which allows accurate determination of 239Pu, 240Pu, and 241Am (as a daughter of 241Pu) activities in radioactive particles ...

Multigraph approach to quantum non-locality
(IOP Publishing, 2014-10-08)
Non-contextuality (NC) and Bell inequalities can be expressed as bounds Ω for positive linear combinations S of probabilities of events, S≤Ω. Exclusive events in S can be represented as adjacent vertices of a graph called ...
