Perception of a blending odor mixture: an fMRI study in humans
2012
Supported by grants from the Burgundy Regional council and EU-ERDF, European Dijon-Dresden Laboratory (LEA 549); Odors we perceive from our environment arise from the processing of mixtures of odorants. Some mixtures can lead to configural or elemental perception depending, in part, on experience. However, the neural bases of such influences are still unknown. In the present study, we examined the neurophysiological correlates of the configural and elemental processing of a binary odor mixture (AB). This AB mixture has previously been shown to blend into one percept, but also to produce a more or less configural perception depending on pre-exposure to either the mixture itself or to the sin…

L'homosexualité et la constitution de la famille : situations française et européenne
2016
The 2013-404 law of 17 May 2013 which opened up the possibility for people of the same gender to get married shows a turning point for the family rights in France. This law, sometimes described as a real tsunami, is the outcome of taking into account the homosexuals' claim for starting a family. Before 2013 the French right did not allow a homosexual couple to be a homoparental family. It did not authorize people of the same gender to get married. Moreover Assisted Reproduction is only reserved to heterosexual couples and Gestation for Others is strictly forbidden in France. This seemingly constrained consensus on the non-legal recognition of the homosexual family is reinforced by the Europ…
The role of virtual work in Levi-Civita's parallel transport
2015
International audience; According to current history of science, Levi-Civita introduced parallel transport solely to give a geometrical interpretation to the covariant derivative of absolute differential calculus. Levi-Civita, however, searched a simple computation of the curvature of a Riemannian manifold, basing on notions of the Italian school of mathematical physics of his time: holonomic constraints, virtual displacements and work, which so have a remarkable, if not dominant, role in the origin of parallel transport.

Developing a framework for designing humanitarian blockchain projects
2021
International audience; Blockchain technology promises to improve the efficiency, transparency, and accountability of humanitarian operations. Yet at the same time, especially the humanitarian context with its characteristic volatility poses unique challenges to any technology. Most prominent are the humanitarian principles that are fundamental to humanitarian operations. These ethical principles are set to protect the most vulnerable populations. Designing blockchain projects in the humanitarian context therefore requires a systematic framework that helps humanitarians make critical choices.While some design instructions can be found for commercial applications, the humanitarian context re…
Observateur et contrôle optimal : améliorer l'efficacité de la conduite automobile avec Kalman et Pontryagin
2010
The PhD presents a combined approach to improving individual car efficiency. An optimal observer, the Extended Kalman Filter, is used to create an efficiency model for the car. Particular attention was paid to handling the asynchronous and redundant nature of the measurement data. A low-cost sensor suite developed to measure data is described. This sensor suite was installed on multiple vehicles to good success. It employsan accelerometer, gps, fuel injector timer, and Vss input to measure all the data necessary to reconstruct the car's state. This observer and sensor suite can be used as the base for any study which requires car efficiency maps, allowing research to proceed without manufac…
Excitons in few-layer hexagonal boron nitride: Davydov splitting and surface localization
2018
Hexagonal boron nitride (hBN) has been attracting great attention because of its strong excitonic effects. Taking into account few-layer systems, we investigate theoretically the effects of the number of layers on quasiparticle energies, absorption spectra, and excitonic states, placing particular focus on the Davydov splitting of the lowest bound excitons. We describe how the inter-layer interaction as well as the variation in electronic screening as a function of layer number $N$ affects the electronic and optical properties. Using both \textit{ab initio} simulations and a tight-binding model for an effective Hamiltonian describing the excitons, we characterize in detail the symmetry of t…
