Monte Carlo simulation is an essential tool in emission tomography that can assist the design of new medical imaging devices, optimization acquisition protocols and development or assessment image reconstruction algorithms correction techniques. GATE, Geant4 Application for Tomographic Emission, encapsulates libraries to achieve a modular, versatile, scripted toolkit adapted field nuclear medicine. In particular, GATE allows description time-dependent phenomena such as source detector...
The current standard model of cosmology successfully describes a variety measurements, but the nature its main ingredients, dark matter and energy, remains unknown. is medium-class mission in Cosmic Vision 2015--2025 programme European Space Agency (ESA) that will provide high-resolution optical imaging, as well near-infrared imaging spectroscopy, over about 14\,000\,deg$^2$ extragalactic sky. In addition to accurate weak lensing clustering measurements probe structure formation half age...
The Near-Infrared Spectrometer and Photometer (NISP) on board the Euclid satellite provides multiband photometry R>=450 slitless grism spectroscopy in 950-2020nm wavelength range. In this reference article we illuminate background of NISP's functional calibration requirements, describe instrument's integral components, provide all its key properties. We also sketch processes needed to understand how NISP operates is calibrated, technical potentials limitations. Links articles providing more...

Nous revenons d’abord genèse diversité fondements normatifs participation puis précisons contours respectifs environnementale concertée l’environnement. nous attachons ensuite au fonctionnement concret travers, d’une part, présentation trois formes (commissions, débats publics jurys citoyens)...
Euclid will be the first space mission to survey most of extragalactic sky in 0.95-2.02 $\mu$m range, a 5$\sigma$ point-source median depth 24.4 AB mag. This unique photometric data set find wide use beyond Euclid's core science. In this paper, we present accurate computations Y_E, J_E and H_E passbands used by Near-Infrared Spectrometer Photometer (NISP), associated system. We pay particular attention passband variations field view, accounting among others for spatially variable filter...
The nature of b-quark jet hadronisation has been investigated using data taken at the Z peak by DELPHI detector LEP. Two complementary methods are used to reconstruct energy weakly decaying b-hadrons, $E_{\mathrm{B}}^{\mathrm{weak}}$ . average value $x^{\mathrm{weak}}_{\mathrm{B}} = E_{\mathrm{B}}^{\mathrm{weak}}/E_{\mathrm{beam}}$ is measured be 0.699±0.011. resulting $x^{\mathrm{weak}}_{\mathrm{B}}$ distribution then analysed in framework two choices for perturbative contribution (parton...
De nombreux travaux se sont efforcés, ces dernières années, d’établir les contours d’un mode d’existence sociale des objets échappant au double écueil naturaliste et constructiviste. Sur cette base, nous montrons comment il est possible de renouveler théories l’action l’acteur. Nous suggérons notamment qu’il convient doter l’acteur sens ordinaire l’objectivité, qui rend compte ses possibilités d’engagement dans une large gamme rapport aux objets. Dans seconde partie, passons en revue...
A search for pair-produced doubly charged Higgs bosons has been performed using the data collected by DELPHI detector at LEP centre-of-mass energies between 189 and 209 GeV. No excess is observed in with respect to Standard Model background. lower limit mass of 97.3 GeV/c2 95% confidence level set left–right symmetric models any value Yukawa coupling τ leptons.
L'idée selon laquelle les profanes sont à même de coproduire des connaissances ésotériques, d'apprivoiser et coévaluer projets techniques s'est progressivement répandue. Les controverses liées l'environnement nous conduisent toutefois prendre au sérieux deux autres phénomènes : d'une part, le refus personnes ordinaires s'engager dans multiples arènes participation qui leur offertes ; d'autre la capacité mêmes résister manière radicale, mais "robuste", c'est-à-dire recevable par un autrui...
Single photons detected by the DELPHI experiment at LEP2 in years 1997–2000 are reanalysed to investigate existence of a single extra dimension modified ADD scenario with slightly warped large dimensions. The data collected centre-of-mass energies between 180 and 209 GeV for an integrated luminosity ∼650 pb−1 agree predictions Standard Model allow limit be set on graviton emission one dimension. obtained fundamental mass scale M D is 1.69 TeV/c 2 95% CL, expected 1.71 2.
