Déchiffrer le passé d'un empire: Hommage à Nicolas Vatin et aux humanités ottomanes
No full textInternational audienceNicolas Vatin is the author of a major work on the history of the Ottoman Empire, especially during the 15th and 16th centuries. Following his nomination to the Académie des Inscriptions et Belles-Lettres, thirty-four of his friends and colleagues from nine different countries wished to pay tribute to him. Their contributions, written in French and English (and one in German), are edited by Elisabetta Borromeo, Frédéric Hitzel, and Benjamin Lellouch. Organized around eight themes, they touch on Nicolas Vatin's numerous areas of study: Ottoman historiography, the Ottoman conquest, diplomatic relations between East and West, the Ottoman elites, Ottoman identity, piracy in the Mediterranean, funerary epigraphy..

Measurement of |Vcb| with B0s→D(*)−sμ+νμ decays
No full textThe element |Vcb| of the Cabibbo-Kobayashi-Maskawa matrix is measured using semileptonic B0s decays produced in proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. Rates of B0s→D−sμ+νμ and B0s→D*−sμ+νμ decays are analyzed using hadronic form-factor parametrizations derived either by Caprini, Lellouch and Neubert (CLN) or by Boyd, Grinstein and Lebed (BGL). The measured values of |Vcb| are (41.4±0.6±0.9±1.2)×10−3 and (42.3±0.8±0.9±1.2)×10−3 in the CLN and BGL parametrization, respectively. The first uncertainty is statistical, the second systematic, and the third is due to the external inputs used in the measurement. These results are in agreement with those obtained from decays of B+ and B0 mesons. They are the first determinations of |Vcb| at a hadron-collider experiment and the first using B0s meson decays
Measurement of Differential Distributions of and Implications on
No full textWe present a measurement of the differential shapes of exclusive ( and ) decays with
hadronic tag-side reconstruction for the full Belle data set of
integrated luminosity. We extract the
Caprini-Lellouch-Neubert (CLN) and Boyd-Grinstein-Lebed (BGL) form factor
parameters and use an external input for the absolute branching fractions to
determine the Cabibbo-Kobayashi-Maskawa matrix element and find

preliminary beyond zero-recoil lattice QCD calculations on the

forward-backward asymmetry and their difference , and the electron and muon longitudinal polarization fraction and
their difference . The
uncertainties quoted correspond to the statistical and systematic
uncertainties, respectively

A Martian PFS average spectrum: Comparison with ISO SWS
No full textThe evaluation of the planetary Fourier spectrometer performance at Mars is presented by comparing an average spectrum with the ISO spectrum published by Lellouch et al. [2000. Planet. Space Sci. 48, 1393.]. First, the average conditions of Mars atmosphere are compared, then the mixing ratios of the major gases are evaluated. Major and minor bands of CO2 are compared, from the point of view of features characteristics and bands depth. The spectral resolution is also compared using several solar lines. The result indicates that PFS radiance is valid to better than 1% in the wavenumber range 1800-4200 cm-1 for the average spectrum considered (1680 measurements). The PFS monochromatic transfer function generates an overshooting on the left-hand side of strong narrow lines (solar or atmospheric). The spectral resolution of PFS is of the order of 1.3 cm-1 or better. A large number of narrow features to be identified are discovered. © 2005 Elsevier Ltd. All rights reserved
Measurement of vertical bar V-cb vertical bar with B-s(0) -> D-s(()*()-) mu(+)nu(mu) decays
No full textThe element vertical bar V-cb vertical bar of the Cabibbo-Kobayashi-Maskawa matrix is measured using semileptonic B-s(0) decays produced in proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb(-1). Rates of B-s0 -> D-s(-) mu(+)nu(mu) and B-s0 -> D-s*(-) mu(+)nu(mu) decays are analyzed using hadronic form-factor parametrizations derived either by Caprini, Lellouch and Neubert (CLN) or by Boyd, Grinstein and Lebed (BGL). The measured values of vertical bar V-cb vertical bar are (41.4 +/- 0.6 +/- 0.9 +/- 1.2) x 10(-3) and (42.3 +/- 0.8 +/- 0.9 +/- 1.2) x 10(-3) in the CLN and BGL parametrization, respectively. The first uncertainty is statistical, the second systematic, and the third is due to the external inputs used in the measurement. These results are in agreement with those obtained from decays of B+ and B-0 mesons. They are the first determinations of vertical bar V-cb vertical bar at a hadron-collider experiment and the first using B-s(0) meson decays.LPHEPublished by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license
Measurement of the CKM matrix element vertical bar V-cb vertical bar from B-0 -> D*(-)l(+)nu(l) at Belle
No full textWe present a new measurement of the Cabibbo-Kobayashi-Maskawa matrix element vertical bar V-cb vertical bar from B-0 -> D*(-)l(+)nu(l) decays, reconstructed with the full Belle data set of 711 fb(-1) integrated luminosity. Two form factor parametrizations, originally conceived by the Caprivi-Lellouch-Neubert (CLN) and the Boyd, Grinstein and Lebed (BGL) groups, are used to extract the product F(1)eta(EW)vertical bar V-cb vertical bar and the decay form factors, where F(1) is the normalization factor and eta(EW) is a small electroweak correction. In the CLN parametrization we find F(1)eta(EW)vertical bar V-cb vertical bar = (35.06 +/- 0.15 +/- 0.56) x 10(-3), rho(2) = 1.106 +/- 0.031 +/- 0.007, R-1 (1) = 1.229 +/- 0.028 +/- 0.009, R-2(1) = 0.852 +/- 0.021 +/- 0.006. For the BGL parametrization we obtain ,F(1)eta(EW)vertical bar V-cb vertical bar = (34.93 +/- 0.23 +/- 0.59) x 10(-3), which is consistent with the world average when correcting for F(1)eta(EW). The branching fraction of B-0 -> D*(-)l(+)nu(l )is measured to be B(B-0 -> D*(-)l(+)nu(l))= (4.90 +/- 0.02 +/- 0.16)%. We also present a new test of lepton flavor universality violation in semileptonic B decays, B(B-0 -> D*(-)e(+)nu)/B(B-0 -> D*(-)mu(+)nu) = 1.01 +/- 0.01 +/- 0.03. The errors quoted correspond to the statistical and systematic uncertainties, respectively. This is the most precise measurement of F(1)eta(EW)vertical bar V-cb vertical bar and form factors to date and the first experimental study of the BGL form factor parametrization in an experimental measurement.LPH
Low-carbon comfort management for smart buildings
No full textWe present critical research challenges for the development of smart building management systems (BMS) to achieve low-carbon comfort. To date, work in this area has focused on optimising single-scope aspects of building resources, such as energy usage or thermal comfort, but there is a recent shift toward BMS design that could simultaneously address many aspects of building resources and comfort dimensions for occupants, such as air quality, temperature, humidity, audible noise levels, and related automated safety features. In this paper, we discuss four research directions highlighting current challenges in this domain that present opportunities for research: (A) data limitations for machine learning, (B) multiple definitions of comfort, (C) BMS usability and interfaces, and (D) safety and security of automated BMS decision-making. Addressing these challenges will enable the development of advanced human-centred energy-saving buildings that meet the needs of occupants
