Introduction. Les pensées monétaires dans l'Europe moderne : contexte et intentions
2014
Ce texte introduit le livre et présente ses objectifs et sa structure. Ce livre traite du déploiement des idées monétaires dans le monde européen de l'époque moderne, depuis les écrits de Nicolas Copernic (1517) jusqu'à la veille de la publication de l'ouvrage économique majeur écrit par Adam Smith (1776) . Il met l'accent sur le contexte historique dans le cadre duquel ces idées monétaires ont vu le jour. Il montre la grande variété des contextes et des idées bien au-delà des espaces, des auteurs et des thèmes généralement étudiés, en intégrant des territoires peu étudiés par les économistes, en mettant au jour des approches et des auteurs oubliés, en tentant, enfin, de restituer la riches…
Thermodynamics of a Phase-Driven Proximity Josephson Junction
2019
We study the thermodynamic properties of a superconductor/normal metal/superconductor Josephson junction {in the short limit}. Owing to the proximity effect, such a junction constitutes a thermodynamic system where {phase difference}, supercurrent, temperature and entropy are thermodynamical variables connected by equations of state. These allow conceiving quasi-static processes that we characterize in terms of heat and work exchanged. Finally, we combine such processes to construct a Josephson-based Otto and Stirling cycles. We study the related performance in both engine and refrigerator operating mode.
Crosstalk of the plasma contact system with bacteria.
2012
Activation of the plasma contact system triggers several cascade systems such as the kallikrein-kinin system, the intrinsic pathway of coagulation, the classical complement cascade and the fibrinolytic system. Recent studies have shown a critical role of the contact system for arterial and venous thrombus formation and thromboembolic disease. In contrast, the function of the contact system for host-defense reactions and its physiological functions have remained enigmatic. Experimental animal studies and clinical data have linked the contact system to bacterial infections with implications for sepsis disease. The present review summarizes the role of the contact system and its activation for…
Incoherent solitons and condensation processes
2006
International audience; We study the nonlinear interaction of partially incoherent nonlinear optical waves. We show that, in spite of the incoherence of the waves, coherent phase effects may play a relevant role during the propagation, in contrast with the usual wave turbulence description of the interaction. These nonlinear phase effects may lead the system to unexpected processes of self-organization, such as condensation, or incoherent soliton generation in instantaneous response nonlinear media. Such self-organization processes may be characterized by a reduction of the non-equilibrium entropy, which violates the Boltzmann's H-theorem of entropy growth inherent to the wave turbulence th…
General approach to spatiotemporal modulational instability processes
2011
International audience; In this article, we derive the general exact solution of the modulation instability gain. The solution described here is valid for 1-D, 2-D, and 3-D cases considering any temporal response function of the medium and with possible higher order Kerr nonlinearities. In particular, we show that the gain induced by modulation instability is initial condition dependent, while the usual calculations do not lead to such a dependence. Applications for current and high-interest nonlinear propagation problems, such as 1-D optical fiber propagation with delayed Raman response and 2-D filamentation in gases, are investigated in detail. More specifically, we demonstrate that the 2-D …
Numerical study of the Kerr solution in rotating coordinates
2016
International audience; The Kerr solution in coordinates corotating with the horizon is studied as a testbed for a spacetime with a helical Killing vector in the Ernst picture. The solution is numerically constructed by solving the Ernst equation with a spectral method and a Newton iteration. We discuss convergence of the iteration for several initial iterates and different values of the Kerr parameters.

Reconciling the Evidence on the Knowledge-capital Model
2005
The Knowledge Capital Model (KC-model), described in Markusen (2002), encompasses both market size (horizontal) as well as factor endowment (vertical) explanations to why multinational production occurs. Although the KC-model seems intuitively appealing, the empirical support has, so far, been weak and even confused. In this study, we find strong, robust and consistent support for the KC-model. In contrast to previous studies, our skill measures follow directly from the model. We also use an enlarged dataset, where the data coverage is significantly improved. Our results also give estimated surfaces remarkably similar to theoretical simulations of the KC-model. In addition, the results give…
