    Although the idea of Europe dates back to ancient times and was crystallised in the Enlightenment, the plan for European unification emerged in the second half of the 20th century as a consequence of an economic process based on a single market and a single currency. European integration is therefore a recent chapter in the history of Europe, one which has been written before our very eyes, but it remains fragmented into disparate national histories. In the 21st century, those writing the history of Europe find themselves confronted with a threefold challenge: they must meet the demands of the digital age, adjust to the paradigm shift within the historical discipline and navigate the geopolitical upheavals that the continent has been experiencing since 1989 (the fall of communism; the enlargement of the European Union; the many crises the EU has faced, including Brexit; the divide between institutions and citizens; the socio-economic consequences of the global crisis, including the COVID-19 health crisis; the new nature of transatlantic relations, etc.).

    Our working hypothesis is that key factors in COVID-19 imaging are the available imaging data and their label noise and confounders, rather than network architectures per se. Thus, we applied existing state-of-the-art convolution neural network frameworks based on the U-Net architecture, namely nnU-Net [3], and focused on leveraging the available training data. We did not apply any pre-training nor modi ed the network architecture. First, we enriched training information by generating two additional labels for lung and body area. Lung labels were created with a public available lung segmentation network and weak body labels were generated by thresholding. Subsequently, we trained three di erent multi-class networks: 2-label (original background and lesion labels), 3-label (additional lung label) and 4-label (additional lung and body label). The 3-label obtained the best single network performance in internal cross-validation (Dice-Score 0.756) and on the leaderboard (Dice- Score 0.755, Haussdor 95-Score 57.5). To improve robustness, we created a weighted ensemble of all three models, with calibrated weights to optimise the ranking in Dice-Score. This ensemble achieved a slight performance gain in internal cross-validation (Dice-Score 0.760). On the validation set leaderboard, it improved our Dice-Score to 0.768 and Haussdor 95- Score to 54.8. It ranked 3rd in phase I according to mean Dice-Score. Adding unlabelled data from the public TCIA dataset in a student-teacher manner signi cantly improved our internal validation score (Dice-Score of 0.770). However, we noticed partial overlap between our additional training data (although not human-labelled) and nal test data and therefore submitted the ensemble without additional data, to yield realistic assessments.

    As we mark the 50th anniversary of the Werner Report, it is well worth analysing the role of Economic and Monetary Union at a time of uncertainty as to the wider European project, via an interdisciplinary approach that draws on historical and archive research and takes into consideration the theoretical debates in the literature and the various methodological challenges.What are the multifaceted future provocation facing Economic and Monetary Union? What steps still need to be taken to complete the project? How can we strengthen the international role of the euro and bolster Europe’s economic and financial autonomy? How can we best tackle technological developments in the field of money and finance? And how is the COVID-19 crisis testing the boundaries of the European integration?

    Master; What can history teach us about the potential long-term consequences of COVID-19? In this lecture, Victor Gay discusses how past pandemics impacted individuals and societies over the long run, and which of their aspects can and cannot be a guide to understand the implications of the current crisis.

    The Schengen Area is one of the pillars of the European project. But it has been affected by several difficulties: the serious consequences of the global economic and financial crisis (2008-2018), growing concerns over external migratory pressure and the question of enlargement, fears of social dumping and, since March 2020, the COVID-19 crisis. Identifying these obstacles is vital so that pragmatic solutions can be found without jeopardising the founding principle.

    Doctoral; La responsabilité sociale de l'entreprise (RSE) après l'Accords de Paris de 2015 et la pandémie covid-19 de 2020 Résumé Ce texte est organisé de la manière suivante. Après une introduction qui justifie la référence à l'Accord de Paris de 2015 et à la pandémie covid-19 de 2020, il aborde successivement : la RSE après la COP21de la gouvernance partenariale à la gouvernance par consensus ; des « parties prenantes » aux « parties intéressées » ; des communs (commons) aux communs informationnels, aux communs globaux et à la gouvernance (la tragédie des communs et la tragédie des anti-communs ; E. Ostrom et la réponse territorialisée à la tragédie des communs ; B. Coriat et les communs informationnels ; R. Petrella et les communs globaux) ; de la gouvernance ; de la gouvernance multi-niveaux ; gouvernances sectorielles, RSE et développement durable (la gouvernance verte ; la gouvernance de l'eau ; la gouvernance minière ; la gouvernance forestière) ; la scène : Sommets de la Terre et COP (Conference of the Parties) ; un premier signal : la modification des enjeux et du contenu du reporting extra-financier ; une focus sur le « principe (devoir et plan) de vigilance » ; Principes d'invclusiveness, de matérialité et de responsiveness ; la Plateforme nationale d'action globale pour la RSE ; le « Plan d'Actions Lima Paris » ; un focus sur le Carbon Disclosure Project ; le French Pledge (l'engagement français) ; la comptabilité carbone ; la norme ISO 14001 (système de management environnemental) ; la norme 50001 (système de management de l'énergie) ; le « bilan carbone » ; l'analyse en cycle de vie (ACV) ; un focus sur les tentatives françaises d'une comptabilité élargie à l'environnement (Care-TDL ; la Comptabilité Universelle ; Adess Logic ; comparaison des trois méthodes) ; le contexte institutionnel français avant la COP21 (la loi sur les nouvelles régulations économiques-NRE ; la référence au « facteur 4 » ; le Grenelle Environnement) ; deux approches émergentes : le GHG Protocol et le « bilan carbone » ; la loi de Transition énergétique pour une croissance verte (TECV) du 17 août 2015 ; les autres initiatives ; un focuq sur le principe d'accountability (responsabilité).
