Precise measurement of the top quark mass in dilepton decays using optimized neutrino weighting
2016
We measure the top quark mass in dilepton final states of top-antitop events in proton-antiproton collisions at sqrt(s) = 1.96 TeV, using data corresponding to an integrated luminosity of 9.7 fb^-1 at the Fermilab Tevatron Collider. The analysis features a comprehensive optimization of the neutrino weighting method to minimize the statistical uncertainties. We also improve the calibration of jet energies using the calibration determined in top-antitop to lepton+jets events, which reduces the otherwise limiting systematic uncertainty from the jet energy scale. The measured top quark mass is mt = 173.32 +/- 1.36(stat) +/- 0.85(syst) GeV.
Translation as a measure of literary domination: the case of Quebec literature translated in Spain (1975-2004)
2010
Recent literary manifestos claim that “the center is no longer the center” (Le Devoir 2007). Indeed, it is generally admitted that Quebec literature has been more or less independent from the French field since the 1970’s. However, the analysis of the translation of this literature –its international circulation, and the almost compulsory stopover in France before being selected for translation by the agents of other literary fields– reveals various mechanisms through which the French symbolic center still exerts its power. Drawing on the application of Pierre Bourdieu’s sociology of culture to the international space (Casanova 1999; Sapiro 2007, 2008; etc.), this article argues that transl…
The effect of buyer specific-monitoring procedures on buyer control in dynamic supply chain links
2015
Based on transaction cost analysis (TCA), resource dependency theory (RDT), and supply chain management literature, this study explores the effect of buyer-specific monitoring procedures on buyer control in industrial buyer-seller transactions, particularly in relation to how environmental uncertainty affects the buying firm's ability to exercise control over the supplier firm. The research design is based on primary data from a survey of 168 industrial buyer-seller relationships which map a broad set of dimensions of the economic transactions and structures in these business-to-business relationships. The empirical findings provide support for the hypotheses, and demonstrate that the effec…
Driving Through Neoliberalism : Finnish Truck Drivers Constructing Respectable Male Worker Subjectivities
2017
This chapter analyses how Finnish male truck drivers (re)produce themselves as respectable male workers in the face of the recent economic, technological and institutional transformations impacting the European haulage sector. The investigation is based on ethnographic data which are produced by riding along on assignments with ten male Finnish truck drivers in the period 2012–2016. The analysis shows how truck drivers’ independence and value in the work process has become challenged and how truckers experience being occupationally stigmatized. The study argues, however, that while economic restructuring undermines some components of traditional forms of working-class masculinity, masculine…
Voltammetric Investigation on Uranyl Sorption by Alginate Based Material. Influence of Hydrolysis and pH Dependence
2015
The removal of U(VI) as uranyl (UO22+) from aqueous solutions was investigated by sorption onto alginate based material. The hydrolysis of uranyl ion was always taken into account in the calculations of free (22UO) ion in aqueous solution, in the experimental pH range considered, as well as the acid-base properties of alginate polymer. The sorption process follows a pseudo-second order kinetic model and the sorption rate decreases when the pH value increases. In addition to the classical Langmuir and Freundlich models, the equilibrium data were fitted by using a modified multi-component equilibrium model, never tested before. Differential Pulse Voltammetry (DPV) and Inductively Coupled Plas…
Practical design rules for single-channel ultra high-speed dense dispersion management telecommunication systems
2009
International audience; In this work, we establish some efficient and practical design rules for the implementation of single-channel ultra-high speed (>160-Gbit/s) telecommunication systems based on dense dispersion management. Moreover, we analyze some of actual implementation issues such as slope compensation scenario, junction losses, polarization mode dispersion and chromatic dispersion fluctuations.
Some Thoughts on the Independence of Party-Appointed Expert in International Arbitration
2021
Participation of experts in both commercial arbitration proceedings and investment arbitration proceedings is a well-known phenomenon for decades. A trend asking for parties-appointed experts to be independent is under development since the end of the twentieth century. The aim of this chapter is, at first, to make the point on this issue by analysing some of the most important current rules dedicated to international arbitration. The observation to be made is that the evolution described is not that developed so far in international arbitration. In a second time the need and relevance of this new requirement are addressed. It appears then that the meaning of this demand is far from being c…
Complex-Valued Independent Component Analysis of Natural Images
2011
Linear independent component analysis (ICA) learns simple cell receptive fields fromnatural images. Here,we showthat linear complex-valued ICA learns complex cell properties from Fourier-transformed natural images, i.e. two Gabor-like filters with quadrature-phase relationship. Conventional methods for complex-valued ICA assume that the phases of the output signals have uniform distribution. We show here that for natural images the phase distributions are, however, often far from uniform. We thus relax the uniformity assumption and model also the phase of the sources in complex-valued ICA. Compared to the original complex ICA model, the new model provides a better fit to the data, and leads…
The publication of news about the results of R+D+I. How do Spanish researchers perceive it?
2018
El objetivo de este estudio es conocer cúal es la percepción que tienen los investigadores de las universidades españolas sobre el impacto que generan, sobre sus carreras profesionales, las noticias científicas que se publicancon los resultados de sus actividades de Investigación, Desarrollo e Innovación (I+D+i). Para ello, se han seleccionado los datos obtenidos por una encuesta online realizada en el año 2016 de 602 investigadores y profesionales de la comunicación científica de 20 universidades de España, teniendo único requisito que alguna de sus publicaciones hubiera sido objeto de —al menos— una nota de prensa difundida por su universidad en los últimos cinco años. Para el…
Pressure Dependence of the Band Gaps and Charge Densities in Si
1994
The empirical local and nonlocal pseudopotentials of Si which can describe the electronic energy structure over a wide energy range of more than 20 eV from the bottom of the valence band is determined for different pressures. The nonlocality of the potential is described by the Gaussian model. The predictions for the linear and quadratic pressure coefficients are consistent with the experiment. The valence charge densities of Si under high pressure are studied. The forbidden X-ray factor F(222) is very stable under pressure and changes by less than 3% under volume changes of the order of 5%.
