Standard skin prick testing and sensitization to inhalant allergens across Europe - a survey from the GA²LEN network.
2005
Skin prick testing (SPT) is the standard method for diagnosing allergic sensitization but is to some extent performed differently in clinical centres across Europe. There would be advantages in harmonizing the standard panels of allergens used in different European countries, both for clinical purposes and for research, especially with increasing mobility within Europe and current trends in botany and agriculture. As well as improving diagnostic accuracy, this would allow better comparison of research findings in European allergy centres. We have compared the different SPT procedures operating in 29 allergy centres within the Global Allergy and Asthma European Network (GA2LEN). Standard SPT…
An Efficient Hardware Architecture for the HEVC Intra Prediction
2014
International audience; A novel intra prediction hardware architecture forthe High Efficiency Video Coding (HEVC) is presented in thispaper in order to reduce the computation complexity within thisstandard and to accelerate the concerned calculations, and thusto process more and more of video frames at high resolutions. Wepropose a new pipelined structure that we called ProcessingElement (PE) to calculate the angular prediction modes, and werepeat it in three paths that our design composed of. And wepresent, in this paper, a dynamic structure to carry out thePlanar mode. This architecture supports all intra predictionmodes for 8x8 and 4x4 prediction unit sizes. The synthesis resultsshow tha…
Armonizzazione degli inventari forestali nazionali in Europa: l’azione COST E47.
2005
Dal quadro complessivo dell’attuale situazione sulle conoscenze delle risorse forestali a livello europeo emerge, sia sotto il profilo delle problematiche sottese, sia sotto il profilo delle possibili soluzioni, la necessità di un maggiore coordinamento e uniformazione degli sforzi connessi all’inventariazione e monitoraggio dei sistemi forestali. Orientata a tale prospettiva è l’azione COST E43 - ENFIN (Harmonisation of National Inventories in Europe: Techniques for Common Reporting) dedicata allo studio delle potenzialità di armonizzazione degli Inventari Forestali Nazionali in Europa. Nel presente lavoro vengono descritti gli obiettivi specifici, l’articolazione e le linee operative di q…
An Overview of 5G Slicing Operational Business Models for Internet of Vehicles, Maritime IoT Applications and Connectivity Solutions
2021
Identification of ecosystems and Business Models (BM) is an important starting point for new complex system development. The definition of actor (or stakeholder) roles and their interactions (at both business and technical levels), together with target scenarios and use cases, provide essential input information for further system requirement collection and architecture specification. The powerful and flexible Fifth Generation (5G) network slicing technology, which is capable of creating virtually isolated and logically parallel networks, enables a large range of complex services and vertical applications. Although various terminologies and models have been proposed in recent years for BMs …
Dispersive magnetic immunoaffinity extraction. Anatoxin-a determination.
2017
Specific monoclonal antibodies were coupled with magnetic Sepharose-based beads and used, for the first time. The methodology was applied to preconcentrate anatoxin-a from water and the later determination by ion mobility spectrometry (IMS). Dispersive magnetic immunoaffinity (d-MagIA) extraction methodology provided a limit of detection of 0.02μgL-1 and a satisfactory precision with a relative standard deviation lower than 15%. Recoveries were evaluated at 0.5, 1.0 and 5.0μgL-1 anatoxin-a with quantitative values from 91 to 115%. Additionally, isobaric interferences with phenylalanine were completely avoided by the use of the developed d-MagIA extraction coupled to IMS determinations.
Las revistas científico-técnicas españolas de ciencias de la actividad física y el deporte: adecuación a las normas ISO y grado de normalización
2004
Este artículo tiene por objeto conocer el grado de normalización y la adecuación de las revistas científico-técnicas españolas del campo de las Ciencias de la Actividad Física y el Deporte a diversos apartados clave de las normas ISO 8-1977 e ISO 215-1986. A partir de la observación directa de los fascículos, se han confeccionado dos índices para calcular el Grado General de Normalización (GGN) y el Grado Fundamental de Normalización (GFN). Los resultados indican que el ajuste de las publicaciones a la norma ISO 8-1977 es equivalente a la de otros campos españoles como el de Economía y el de Tecnología, mientras que es menor en la norma ISO 215-1986. La mayoría de las revistas presentan un …
Searches for B0 decays to combinations of charmless isoscalar mesons
2004
We search for B meson decays into two-body combinations of eta, eta', omega, and phi mesons from 89 million B B-bar pairs collected with the BaBar detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We find the branching fraction BF(B0 -> eta omega) = (4.0^{+1.3}_{-1.2} +- 0.4) x 10^-6 with a significance of 4.3 sigma. For all the other decay modes we set the following 90% confidence level upper limits on the branching fractions, in units of 10^-6 : BF(B0 -> eta eta)<2.8, BF(B0 -> eta eta')<4.6, BF(B0 -> eta' eta')<10, BF(B0 -> eta'omega)<2.8, BF(B0 -> eta phi)<1.0, BF(B0 -> eta' phi)<4.5, BF(B0 -> phi phi)<1.5.
A non-parametric segmentation methodology for oral videocapillaroscopic images
2014
We aim to describe a new non-parametric methodology to support the clinician during the diagnostic process of oral videocapillaroscopy to evaluate peripheral microcirculation. Our methodology, mainly based on wavelet analysis and mathematical morphology to preprocess the images, segments them by minimizing the within-class luminosity variance of both capillaries and background. Experiments were carried out on a set of real microphotographs to validate this approach versus handmade segmentations provided by physicians. By using a leave-one-patient-out approach, we pointed out that our methodology is robust, according to precision-recall criteria (average precision and recall are equal to 0.9…
Noise Induced Phenomena in point Josephson junctions
2008
We present the analysis of the mean switching time and its standard deviation of short overdamped Josephson junctions, driven by a direct current and a periodic signal. The effect of noise enhanced stability is investigated. It is shown that fluctuations may both decrease and increase the switching time.
Differential branching fraction and angular analysis of the decay $B^{0} \to K^{*0} \mu^{+}\mu^{-}$
2013
The angular distribution and differential branching fraction of the decay B-0 -> K*(0)mu(+)mu(-) are studied using a data sample, collected by the LHCb experiment in pp collisions at root s = 7 TeV, corresponding to an integrated luminosity of 1.0 fb(-1). Several angular observables are measured in bins of the dimuon invariant mass squared, q(2). A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system is also presented. The zero-crossing point is measured to be q(0)(2) = 4.9 +/- 0.9 GeV2/c(4), where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions.
