Patterned functional network disruption in amyotrophic lateral sclerosis

2019

Abstract Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease primarily affecting motor function, with additional evidence of extensive nonmotor involvement. Despite increasing recognition of the disease as a multisystem network disorder characterised by impaired connectivity, the precise neuroelectric characteristics of impaired cortical communication remain to be fully elucidated. Here, we characterise changes in functional connectivity using beamformer source analysis on resting‐state electroencephalography recordings from 74 ALS patients and 47 age‐matched healthy controls. Spatiospectral characteristics of network changes in the ALS patient group were quantifi…

Localisation visuelle basée sur la reconnaissance du lieu dans les environnements changeants

2017

In many applications, it is crucial that a robot or vehicle localizes itself within the world especially for autonomous navigation and driving. The goal of this thesis is to improve place recognition performance for visual localization in changing environment. The approach is as follows: in off-line phase, geo-referenced images of each location are acquired, features are extracted and saved. While in the on-line phase, the vehicle localizes itself by identifying a previously-visited location through image or sequence retrieving. However, visual localization is challenging due to drastic appearance and illumination changes caused by weather conditions or seasonal changing. This thesis addres…

Comportements d'acteurs et dynamiques territoriales

1997

National audience; Notre projet est de concevoir un outil d'aide à la décision en matière d'aménagement urbain, s'appliquant aux stratégies de localisation des entreprises commerciales. Il est basé sur la modélisation des interactions entre des acteurs (décideurs, groupes d'agents socio-économiques) et leur territoire. Deux idées fortes sous-tendent ce projet. La première est que l'espace représente un type d 'acteur particulier, qui agit sur le comportement des agents socio-économiques et qui, en retour, est modifié par eux. La seconde consiste à intégrer le raisonnement des équipes municipales (qui sont les décideurs en matière d'aménagement urbain) dans le modèle, afin d'obtenir un outil…

Molecular Electron Density Theory: A Modern View of Reactivity in Organic Chemistry

2016

A new theory for the study of the reactivity in Organic Chemistry, named Molecular Electron Density Theory (MEDT), is proposed herein. MEDT is based on the idea that while the electron density distribution at the ground state is responsible for physical and chemical molecular properties, as proposed by the Density Functional Theory (DFT), the capability for changes in electron density is responsible for molecular reactivity. Within MEDT, the reactivity in Organic Chemistry is studied through a rigorous quantum chemical analysis of the changes of the electron density as well as the energies associated with these changes along the reaction path in order to understand experimental outcomes. St…

Formation et compétitivité des régions européennes

1991

Parc technologique, industrie pilote,... dans la logique de l'aménagement du territoire, l'accent semble de plus en plus mis sur la dotation en ressources humaines d'une zone géographique. Comme, d'autre part, la capacité à exporter conditionne l'essentiel des possibilités de croissance économique, on peut s'interroger sur l'impact d'une forte dotation en capital humain comme avantage absolu des produits sur les marchés extérieurs. Dans une recherche par l'entreprise de source de compétitivité, la localisation dans une région à haut niveau de formation de la main d'oeuvre peut être une stratégie a priori pertinente. Dans ce texte, on tente de donner une explication des performances d'une ré…

Multimodal and multicriteria analysis for VLSI expertises and defects localization

2017

The purpose of this manuscript is to exhibit the research work solving the issue of data processing stem from defect localization techniques. This step being decisive in the failure analysis process, scientists have to harness data coming from light emission and laser techniques. Nevertheless, this analysis process is sequential and only depends on the expert’s decision. This factor leads to a not quantified probability of localization. Consequently to solve these issues, a multimodal and multicriteria analysis has been developped, taking advantage of the heterogeneous andcomplementary nature of light emission and laser probing techniques. This kind of process is based on advanced level too…

La diffusion des NTIC au sein du réseau urbain français et le rôle des acteurs publics

2001

The study deals with the ways in which the general public and the government make use of new information and communication technologies. We analyze the physical locations of Internet sites with “fr” as their domain names. The data were provided by the French NIC center (AFNIC). Using this sample (a quarter of all French sites), we find a rather even distribution of French sites in the Paris area plus the other main French cities, and the remainder of France. In addition, we try to enumerate the initiatives of the public actors responsible for the regional planning of the new information and communication technologies. Firstly, we clarify the economic and legal framework in which public acto…
