A quantitative witness for Greenberger-Horne-Zeilinger entanglement
(Nature Publishing Group, 2012-12)
Along with the vast progress in experimental quantum technologies there is an increasing demand for the quantification of entanglement between three or more quantum systems. Theory still does not provide adequate tools for ...
Black Holes, Cosmological Solutions, Future Singularities, and Their Thermodynamical Properties in Modified Gravity Theorie
(MDPI, 2012-09-18)
Along this review, we focus on the study of several properties of modified
gravity theories, in particular on black-hole solutions and its comparison with those solutions in General Relativity, and on Friedmann–Lemaˆıtr ...
Optimally robust shortcuts to population inversion in two-level quantum systems
(IOP Publishing LTD, 2012-09-21)
We examine the stability versus different types of perturbations of recently proposed shortcuts to adiabaticity to speed up the population inversion of a two-level quantum system. We find the optimally robust processes by ...
Unconventional spin texture of a topologically nontrivial semimetal Sb(110)
(IOP Publishing LTD, 2012-10-17)
The surfaces of antimony are characterized by the presence of spin-split states within the projected bulk band gap and the Fermi contour is thus expected to exhibit a spin texture. Using spin-resolved density functional ...
Stereoselective inverse conjugate addition of nitrogen and carbon nucleophiles to allenyl phosphine oxide. Synthesis of α,β-unsaturated phosphine oxides
(ARKAT USA, Inc, 2012)
[EN] The reactivity of new three carbon synthon, generated in situ from the reaction of electrondeficient allenes with an appropriate phosphine as the catalyst, toward pronucleophilic reagents is described. Triphenylphos ...
Collision tumour involving a rectal gastrointestinal stromal tumour with invasion of the prostate and a prostatic adenocarcinoma
(BioMed Central, 2012)
Background:
Gastrointestinal stromal tumours (GISTs) are the most common primary mesenchymal neoplasia in the gastrointestinal tract, although they represent only a small fraction of total gastrointestinal malignancies ...
Influence of Training Set Selection in Artificial Neural Network-Based Propagation Path Loss Predictions
(Hindawi Publishing Corporation, 2012)
This paper analyzes the use of artificial neural networks (ANNs) for predicting the received power/path loss in both outdoor and indoor links. The approach followed has been a combined use of ANNs and ray-tracing, the ...
Prevalence of Listeria monocytogenes in Idiazabal cheese
(Sociedad Española de Nutrición Parenteral y Enteral, 2012)
[ES] Introducción: Listeria monocytogenes se ha asociado a quesos elaborados a partir de leche cruda, lo que supone un importante riesgo de salud pública debido a la listeriosis.
Objetivo: Estudiar la prevalencia y los ...
Squaring the circle. Social and environmental implications of pre-pottery neolithic building technology at Tell Qarassa (South Syria)
(Public Library of Science (PLoS), 2012-07-27)
We present the results of the microstratigraphic, phytolith and wood charcoal study of the remains of a 10.5 ka roof. The roof is part of a building excavated at Tell Qarassa (South Syria), assigned to the Pre-Pottery ...
Antioxidant defense system and family environment in adolescents with family history of psychosis
(BioMed Central, 2012-11-16)
[EN] Our objective was to determine antioxidant defence activity in healthy controls (HC) and healthy unaffected second-degree relatives of patients with early onset psychosis (HC-FHP),and to assess its relationship with ...
