In situ copper isotope analysis by femtosecond Laser Ablation MultiCollector Inductively Coupled Plasma Mass Spectrometry (fs-LA-MC-ICP-MS) on historical gold coins
No full textInternational audienceThis study investigates the potential of femtosecond laser ablation coupled with multicollector inductively coupled plasma mass spectrometry (fs-LA-MC-ICP-MS) for copper isotopic analysis in gold matrices applied to cultural heritage. Elemental analyses, which have commonly been used so far, provide information on the circulation of metal stocks based on elemental signatures but fail to pinpoint the precise source of gold. In contrast, isotopic analyses can offer a more accurate means of identifying the source of the metal, yet their application to gold matrices remains a challenge. For the first time, we successfully determined copper isotope ratio in gold matrices and achieved repeatabilities of 0.12‰ to 0.26‰ (2SD) for δ65Cu analyses carried out over up to 8 days, demonstrating the feasibility of copper isotopic analyses in gold coins at the micron-scale. This work was conducted using isotopically characterised in-house matrix-matched gold standard with copper concentrations varying from 4.5 wt% to 9.6 wt%. Our results open new avenues of research for provenance studies of precious museum artefacts and archaeological finds, with potential applications in authentication analyses on similar gold materials. The micro-sampling performed by femtosecond laser ablation minimises the damages on such ancient artifacts. However, the Cu concentrations had to be of at least 4 wt% with our analytical set up and a special care must be taken on the laser beam focusing in order to obtain accurate δ65Cu measurements in gold matrices
Le rôle du tirage au sort dans la mise en place des magistratures à Rome aux Ve‑IVe siècles av. J.‑C.
No full textInternational audienceIn Rome, the drawing of lots dates back at least to the creation of the military tribune withconsular power and there is no reason to question its earlier existence. Within the contextof the slow development of the magistracies in the 5th and 4th centuries and of the politicalconflict between patricians and plebeians, sortitio initially ensured, at the time of the militarytribunes with consular power, the distribution of roles and assignments among colleagueswho were of equal rights and elected under the same auspices. However, the institutionalevolution after 367 and the gradual specializing of various functions within the magistracyended up establishing a hierarchy between the different magistracies, a hierarchy partlycreated by the drawing of lots. The sortition was thus an important factor in the evolutionand establishment of the classical system of higher magistracies in Rome.À Rome, le tirage au sort remonte au moins à la création du tribunat militaire à pouvoirconsulaire et il n’y a pas de raison de douter de son existence antérieure. Dans le contextede la lente maturation des magistratures aux Ve et IVe siècles et du conflit politique entrepatriciens et plébéiens, la sortitio permit d’abord, à l’époque des tribuns militaires à pouvoirconsulaire, de répartir les rôles et les missions entre des collègues égaux en droit et élussous les mêmes auspices. Mais l’évolution institutionnelle après 367 et la spécialisationprogressive des différentes fonctions au sein de la magistrature finirent par établir unehiérarchie entre les différentes magistratures, hiérarchie née du tirage au sort. Ce dernierfut donc un facteur important de l’évolution et de la mise en place du système classique desmagistratures supérieures à Rome

An assessment taxonomy for self-adaptation business process solutions
No full textInternational audienceSelf-adaptation of business processes has become the focus of several research studies aiming at avoiding a manual adaptation of processes at run-time, which is error-prone and time-consuming. In fact, several contributions addressing the self-adaptation of processes have been proposed in the literature, but none of them has comprehensively studied and analyzed the literature to assess the current state of progress in the self-adaptation of processes. To address this gap, we propose in this paper a comprehensive taxonomy that identifies a set of characteristics to serve as support for the comparative analysis of solutions addressing self-adaptation of processes. Our taxonomy includes 25 characteristics that address relevant questions regarding self-adaptation of processes. While creating our taxonomy, we built on existing literature and involved academic experts from different universities. These experts did not only validate our taxonomy regarding completeness and understandability, but also rectified and enriched it with their knowledge. Finally, we report the application of this taxonomy to evaluate some existing contributions on self-adaptation of processes
A Non-Integrable Ohsawa-Takegoshi-Type L 2 Extension Theorem
No full textGiven a complete Kähler manifold (X, ω) with finite second Betti number, a smooth complex hypersurface Y ⊂ X and a smooth real d-closed (1, 1)-form α on X with arbitrary, possibly non-rational, De Rham cohomology class {α} satisfying a certain assumption, we obtain extensions to X, with control of their L 2 -norms, of smooth sections of the canonical bundle of Y twisted by the restriction to Y of any C ∞ complex line bundle L k in a sequence of asymptotically holomorphic line bundles whose first Chern classes approximate the positive integer multiples k{α} of the original class. Besides a known non-integrable (0, 1)-connection ∂k on L k , the proof uses two twisted Laplace-type elliptic differential operators that are introduced and investigated, leading to Bochner-Kodaira-Nakano-type (in-)equalities, a spectral gap result and an a priori L 2 -estimate. The main difference from the classical Ohsawa-Takegoshi extension theorem is that the objects need not be holomorphic, but only asymptotically holomorphic as k → ∞. The possibility that ∂k does not square to 0 accounts for its lack of commutation with the Laplacian ∆ ′′ k it induces. We hope this study is a possible first step in a future attack on Siu's conjecture predicting the invariance of the plurigenera in Kähler families of compact complex manifolds.</div

No full textDiversité des légumineuses dans les produits agroalimentaires sous marque : le positionnement africain par rapport à la situation mondiale (2010-2021)
No full textCe volume fait suite aux Rencontres Francophone Légumineuses (RFL) de mars 2024 organisées par le Cirad, INRAE, Terres Inovia et Terres Univia, et co-organisé par l'Institut Sénégalais de Recherches Agricoles (ISRA). Ce rendez-vous unique entre tous les acteurs du développement, des filières et de la recherche sur les légumineuses à graines et fourragères. L’occasion de croiser les regards, partager les connaissances et accélérer l’innovation autour des légumineuses.Les RFLs s’intéressent aux légumineuses à graines, fourragères ou ligneuses, et visent à couvrir la diversité des systèmes de production, ainsi que la diversité des usages : alimentation humaine, animale et non-alimentaire.Les légumineuses sont un levier majeur pour relever les défis mondiaux du changement climatique et de la sécurité alimentaire et nutritionnelle. Partout dans le monde, elles disposent d’un rôle stratégique : atouts nutritionnels, souveraineté protéique et alimentaire. Les nombreuses espèces de légumineuses constituent également un formidable vivier d’innovations alimentaires.National audienceUsing text mining methods, we ituation explored the diversity of pulses used in around 350,000 agri-food products launched on the market over the last decade and referenced in the GNPD-Mintel database. The shares of soya vs other legumes identified as pulses and promoted by the United Nations were compared worldwide. The position of the different species in the list of ingredients and in the products' description have made it possible to assess their relative importance in the branded food offered to consumers. The supremacy of soya was observed worldwide. Such result is confirmed in African countries even if fewer number of products were referenced in those countries. This original method opens up new perspectives for monitoring the use of crops in the food market and its evolution over time and space.Nous avons exploré, grâce à des méthodes de fouilles de texte, la diversité des légumineuses à graines utilisée dans environ 350 000 produits agroalimentaires, lancés sur le marché au cours de la dernière décennie, et référencés par la base GNPD-Mintel. La place du soja et des légumineuses identifiées comme « pulses » et promues par les Nations Unies ont été comparées au niveau mondial. La position des espèces dans la liste des ingrédients et dans la description du produit ont permis d'évaluer leur importance relative dans l'offre alimentaire emballée, vendue sous marque aux consommateurs. La suprématie du soja est observée dans le monde entier. Le cas de l'Afrique ne contraste pas avec ce constat, malgré un nombre de références produits recensés plus faible. Cette méthode inédite ouvre des perspectives pour suivre l'usage des cultures sur le marché alimentaire et son évolution dans le temps et l'espace
