Conductance of a subdiffusive random weighted tree

We work on a Galton--Watson tree with random weights, in the so-called "subdiffusive" regime. We study the rate of decay of the conductance between the root and the $n$-th level of the tree, as $n$ goes to infinity, by a mostly analytic method. It turns out the order of magnitude of the expectation of this conductance can be less than $1/n$ (in contrast with the results of Addario-Berry-Broutin-Lugosi and Chen-Hu-Lin), depending on the value of the second zero of the characteristic function associated to the model. We also prove the almost sure (and in $L^p$ for some $p>1$) convergence of this conductance divided by its expectation towards the limit of the additive martingale.Comment: 22 pages, 2 figure

Invariant Measures, Hausdorff Dimension and Dimension Drop of some Harmonic Measures on Galton-Watson Trees

We consider infinite Galton-Watson trees without leaves together with i.i.d.~random variables called marks on each of their vertices. We define a class of flow rules on marked Galton-Watson trees for which we are able, under some algebraic assumptions, to build explicit invariant measures. We apply this result, together with the ergodic theory on Galton-Watson trees developed in \cite{LPP95}, to the computation of Hausdorff dimensions of harmonic measures in two cases. The first one is the harmonic measure of the (transient) $\lambda$-biased random walk on Galton-Watson trees, for which the invariant measure and the dimension were not explicitly known. The second case is a model of random walk on a Galton-Watson trees with random lengths for which we compute the dimensions of the harmonic measure and show dimension drop phenomenon for the natural metric on the boundary and another metric that depends on the random lengths.Comment: 37 pages, 5 figure

Conclusion: Constraint and Consent in the Transfer of EU Rules 24 Literature 26This working paper investigates the conditions which prompt a variety of non- EU states grouped within an international organization to adopt European rules or standards rather than any alternative rule or standard available for selection. The paper reviews the main conceptual frameworks from research on the bilateral transfer of European rules and highlights similarities between these and alternative explanatory models of rule transfer, diffusion or convergence found in the broader IR literature. After identifying the main differences between bilateral and multilateral rule transfer processes, the paper proposes theoretical amendments to capture the original forms and new channels via which the EU can either impose constraint or seek consent at the multilateral level. On this basis, two hypotheses are formulated whose plausibility is subsequently probed by means of four comparative case studies dedicated to the worldwide transfer or non-transfer of European rules via international organizations

Can Asymmetrical Cooperation Be Legitimised? Habermas, Foucault and Spivak on German-Tunisian Cooperation in Higher Education

This study investigates whether and under which conditions certain forms of cooperation that are characterised by a degree of structural asymmetry among partners may nonetheless be considered legitimate. In investigating this question, the study will operate in three theory-driven sections borrowing from critical theory, post-structuralism and postcolonialism. Each section will provide a brief presentation of the main theoretical arguments developed by one philosopher, illustrated with extensive direct quotes from relevant original works. This presentation will then be followed by a critical summary. For the sake of illustration, theoretical arguments will then be confronted with empirical observations based on my own participation in the 'Tunisia in Transition' project. Section one will argue in favour of the possibility of genuinely horizontal argumentative engagement on the basis of Habermas' discourse 'ethics' and theory of communicative action. By contrast, section two will introduce Foucault’s genealogical account of the power/knowledge interplay to reject the possibility of discursive spaces that would be in a position of exteriority to power relations. Section three will then bring in the writings of Spivak on the double aporia of representation in order to highlight the practical obstacles to a subversive use of the Master’s knowledge by the subaltern for genuinely emancipatory purposes

Impact of aging on the soft error rate of 6T SRAM for planar and bulk technologies

This paper evaluates the impact of aging on the radiation sensitivity of 6T SRAMfor two planar bulk technologies. This study ismotivated by the growing impact of aging and radiation effects on the reliability of CMOS technology. Amodelling methodology dedicated to this newphenomenon is proposed. Thismodelling uses the radiation modelling device MUSCA SEP3 and an electrical aging modelling. First, the impact of aging on SEE sensitivity is studied through a parametric modeling of the threshold voltages of the transistors composing the 6T SRAM. Then, an operative avionics environment is modelled in order to evaluate the consequences on reliability

L’Europe, territoire à construire

This article analyses the consequences of European mobility on social structures in Europe. After reviewing the academic literature available on the migration behavioural patterns of three social groups (students, professionals and pensioners), the article identifies two ideal-typical profiles of European migrants: those predisposed to mobility due to their social and human capital and those whose migration decisions are mediated by the existence of European opportunity structures. The following sections analyse the motivations of European migrants and the consequences of their mobility on host societies. The authors emphasise the importance of network socialisation and underline the increasing europeanisation of some of these networks. The article concludes that it is not possible to identify a “European mobile aristocracy” but rather that, by seizing personal mobility opportunities, migrants create a European territory, which may anticipate the emergence of a European society.Cet article analyse les conséquences des comportements migratoires de trois groupes sociaux (les étudiants, les actifs et les retraités) sur les structures sociales européennes. Après avoir passé en revue l’état de la recherche sociologique sur le sujet, l’article identifie deux profils idéal-typiques de migrants européens : d’une part, les personnes prédisposées à la mobilité par leur capital humain et relationnel et d’autre part, celles dont les décisions de migration dépendent de l’existence de structures d’opportunité au niveau européen. L’étude détaille ensuite, pour chaque groupe social, les motivations des décisions individuelles de migration et analyse les conséquences de la démarche migratoire sur les sociétés d’accueil. Les auteurs soulignent l’importance de la socialisation en réseau et notent l’européanisation accrue de certains de ces réseaux. Cette étude conclut qu’il n’est pas possible d’identifier une classe privilégiée d’Européens mobiles, puisque l’accès à la mobilité s’est considérablement démocratisé et ouvert à de nouvelles catégories socioprofessionnelles. En revanche, l’exercice du droit à la mobilité permet aux migrants européens de s’approprier la géographie européenne et de créer du territoire, ce qui pourrait anticiper l’émergence d’une société européenne
