International audience; transHumUs is an artistic work recently exhibited at the 56th Venice Biennale. The work aims at freeing trees from their roots. How to translate this poetic ambition into technological terms? This paper reports on the setup and the implementation of the project. It shows how state of the art mobile robotics technology can contribute to contemporary art development. The challenge has been to design original mobile platforms carrying charges of three tones, while moving noiseless according to tree metabolism, in operational spaces populated by visitors.

France’s hesitant stance on EU enlargement towards the Balkans is illustrative of a broader ambivalence among both French elites and citizens towards the European project. Despite principled support for the Balkans’ EU membership, achieving this step is no strategic priority for France. The official approach emphasizes strict conditionality and a rigorous monitoring of reform progress in aspirant countries. A hostile public opinion and superficial media coverage further strengthen the country’s reluctance to admit new, possibly unprepared candidates into the Union. Analysing the historical evolution of the French position on EU enlargement as well as its current political, institutional and societal expressions, this article construes France’s disinvestment from the Balkans’ EU perspective as the result of failed expectations and a growing disillusionment with the EU’s international role and its political future more broadly.

International audience; This essay examines the geographic origins, the political belongings and the confessional profiles of the members of the two most important mercantile nations of eighteenth-century southern Italy: the French nation and the British factory of Naples. Taking into account their pronounced prosopographic heterogeneity, it shows how legal resources and their social uses played a crucial role in defining the boundaries of such groups.

International audience; This paper describes the workflow of the Grammateus project, from gathering data on Greek documentary papyri to the creation of a web application. The first stage is the selection of a corpus and the choice of metadata to record: papyrology specialists gather data from printed editions, existing online resources and digital facsimiles. In the next step, this data is transformed into the EpiDoc standard of XML TEI encoding, to facilitate its reuse by others, and processed for HTML display. We also reuse existing text transcriptions available on . Since these transcriptions may be regularly updated by the scholarly community, we aim to access them dynamically. Although the transcriptions follow the EpiDoc guidelines, the wide diversity of the papyri as well as small inconsistencies in encoding make data reuse challenging. Currently, our data is available on an institutional GitLab repository, and we will archive our final dataset according to the FAIR principles.

Cet article présente les résultats de la campagne de terrain menée au Sénégal oriental en 2017 dans le cadre du programme international « Peuplement humain et paléoenvironnement en Afrique ». Il intègre les résultats de deux projets complémentaires : le projet ANR-FNS CheRCHA, ainsi que le projet FNS Falémé. Le premier vise à reconstituer le cadre chronostratigraphique et les évolutions culturelles au Pléistocène et à l'Holocène ancien et moyen dans la vallée de la Falémé, tandis que le second est ciblé sur les dynamiques techniques des deux derniers millénaires au Sénégal oriental.

International audience; Dans l’enquête sur la poléogénèse, le dossier érétrien apparaît singulièrement lacunaire. Érétrie se signale par sa non-fondation. L’autel circulaire du sanctuaire d’Apollon est le premier signe de l’émergence d’une communauté politico-religieuse, mais voici que l’imagerie de la céramique locale prend le relais et témoigne des premières pratiques cultuelles et rituelles dans l’enceinte du sanctuaire : s’ouvrent alors les portes du Soleil

In the field of global history, especially when it comes to « histoire croisée », the use of metaphors describing the vertical organization of a society, its structuration into layers or into overlapping systems, is common. The temptation to use a second metaphor, calling everything a “network”, is also very important in this domain, whose objects of study are often transnational organizations with multiple branches, intertwined within umbrella organizations, sharing board members and including several levels of secretariats and subcommittees (Grandjean 2017). However, the use of these images is not limited to historical studies, since we use the same vocabulary in other disciplines to describe social situations or textual structures. When we go beyond the metaphor to develop a formal analysis, we often produce multigraphs who, because they simultaneously express horizontal and vertical relationships, are generally unsuitable for the analysis (and visualisation, except in very simple cases). If the “exploratory” dimension of social network analysis – and especially the fact that its display is relatively subjective – is often a subject of criticism, we propose here to play with the visual representation to show precisely how an original modelling can improve the reading of complex graphs, and helping to restore a “morphological” (Moretti 1999, 68) information where disorder seems to prevail. Based on two examples from archives mapping and theatre character networks, this paper proposes a reflection on the different ways to take account of verticality in graphs. In particular, we are developing a way to impose a macro-structure to a network, allowing a two-dimensions view that reflects the hierarchical affiliations of its components. We will see that this method, by constructing a stable visual representation in time and space, helps to compare different types of relationships and/or different time states of the graph.

The pigment Prussian blue is studied in heritage science because of its capricious fading behavior under light exposure. We show here that XANES can be used to study the photosensitivity of Prussian blue heritage materials despite X-ray radiation damage. We used an original approach based on X-ray photochemistry to investigate in depth the redox process of Prussian blue when it is associated with a cellulosic substrate, as in cyanotypes and watercolors. By modifying cation and proton contents of the paper substrate, we could tune both rate and extent of Prussian blue reduction. These results demonstrate that the photoreduction and fading of Prussian blue is principally mediated by the substrate and its interaction with the oxygen of the environment.

International audience; We here describe the Rhapsodie resource, a syntactic and prosodic treebank of spoken French, composed of 57 short samples of spoken French (5 minutes long on average, amounting to 3 hours of speech and 33000 words), and an orthographic transcription. The transcription and the annotations are all aligned on the speech signal : phonemes, syllables, words, speakers, overlaps. The main objective of the Rhapsodie project is to define rich, explicit, and reproducible schemes for the annotation of prosody and syntax in different genres (± spontaneous, ± planned, face-to-face interviews vs. broadcast, etc.), in order to study the prosody/syntax/discourse interface in spoken French, and their roles in the segmentation of speech into discourse units. This resource is freely available at www.projet-rhapsodie.fr. The sound samples (wav/mp3), the acoustic analysis (original F0 curve manually corrected and automatic stylized F0, pitch format), the orthographic transcriptions (txt), the macrosyntactic annotations (txt), the prosodic annotations (xml, textgrid), and the metadata (xml and html) can be freely downloaded under the terms of the Creative Commons licence Attribution - Noncommercial - Share Alike 3.0 France. The metadata are encoded in the IMDI-CMFI format and can be parsed on line.
