 The Moon is a cornerstone for understanding the early history (origin, budget and timing) of volatile elements (H, C, F, S, Cl) delivered to all terrestrial planets. The volatile study of lunar magmatism is the most direct way to reconstruct the volatile budget of the Moon’s interior.  However, this reconstruction is compromised by magmatic processes that modify the initial compositions of the lunar magmas. The final goal of our work is to determine how sulfide saturation and segregation in all the compositional range of lunar lavas have affected the sulfur isotopic composition of the magmas. The determined sulfur isotopic fractionation between lunar silicate melts and immiscible sulfide blebs will allow us to directly unravel the sulfur isotopic composition of the heterogeneous reservoirs forming the Moon’s interior, and therefore, provide fundamental information on the early evolution of sulfur isotopes of the Earth’s satellite. 

A rapidly rotating system of strongly interacting matter at high temperature and density has been created and observed in relativistic heavy-ion collision experiments. However, the theoretical framework for describing the dynamical evolution of spin degrees of freedom still requires further development. In this research project, we have formulated a thermodynamic system in which spin is introduced as an external environmental parameter, and we have investigated the thermal properties induced by spin. We have discovered that the spin carried by gauge particles is closely related to the topological current in the gauge sector, opening a novel direction for exploring the nonperturbative nature of hot and dense matter.

What does the study of music look like in an age of ubiquitous data? How have we collected and categorized music, in all its richness? And how can digital tools help us understand musical style and structure, particularly when it comes to the music of the distant past? As my host Philippe Vendrix explains in the introduction to EarlyMuse (https://earlymuse.eu/; a major European Cooperation in Science and Technology [COST] project), the field of early music has always been marked by hybridity: a meeting ground of theory and practice, of scholarship and performance, of the material and the immaterial. Now the digital turn in scholarship, and the central place of digital media in culture more broadly, bring new opportunities and challenges to this mix.
The experimental basis of my project, briefly stated, is to find ways to advance two key axes—one technical, the other social. Thus, one portion of my work will focus on “music as data” and “data about music” at both micro and macro levels of detail. During this phase of work, I will advance techniques for the curation of quality data, the development of algorithms and machine learning systems for music, and the elaboration of systems for mapping and linking knowledge.  But I will also help seasoned professionals and aspiring graduate students alike direct this kind of “applied human intelligence” to the machine tools that increasingly mediate our experience with all forms of culture, and that shape knowledge systems, too. If musicology is to succeed in a digital age, we will need to involve digital natives in this work. And if young musicologists are to succeed in the rapidly changing landscape of the academy and culture industry more broadly, they will need to hone digital skills early in their careers

This study presents a multidimensional framework to evaluate the socio-ecological roles (SER) of insects in agrifood systems. Insects contribute to all four categories of ecosystem services: provisioning, regulating, supporting, and cultural, while also posing context-specific challenges. Using a transdisciplinary approach, we assessed 120 insect species across four dimensions: Productive Potential, Ecosystem Potential, Use, and Challenges. Unsupervised machine learning identified species clusters that provide useful insights for context-specific management strategies, including conservation, pest/vector control, wild gathering, and farming. While some species consistently perform well across dimensions, others require more localised or tailored approaches. Rather than offering definitive answers, this framework provides a starting point to support more adaptive and inclusive decision-making for sustainable insect use. It contributes to balancing productivity, biodiversity, and cultural relevance, while guiding future research and policy efforts aligned with agri-food system transformation and biodiversity goals.

Follicle-stimulating hormone (FSH) binds to G protein-coupled FSH receptors (FSHR) expressed on ovarian granulosa cells in low abundance. Activation of FSHR leads to granulosa cell proliferation, differentiation and estrogen production. These events are essential for female fertility.  FSHR signaling pathway is highly conserved between mice and humans. Inactivating mutations in FSHR-encoding gene in mice (Fshr -/-) or women result in ovarian folliculogenesis arrest and female infertility. High affinity and highly potent human FSHR-specific single-domain antibody fragments (SDAb) will be tested in a humanized mouse model with ovary-targeted expression of human FSHR transgene on a Fshr null genetic background. This model permits evaluation of several reproducitve outcomes and may prove as an essential in vivo genetic tool to study FSHR-mediated signaling in ovarian granulosa cells.

Despite her status as arguably the most represented historical French female figure in French bandes dessinées, Joan of Arc and her depiction in 9th-art works has never been the subject of a full-length analysis. My work on Joan of Arc’s representation in French bandes dessinées explores the unique function France’s most celebrated medieval heroine plays in the country's popular cultures. In addition to a complete survey of the BD corpus and the conventions typically used to depict Joan, I give special attention to cases where she functions as an iconoclastic figure who challenges the enduring culturally gendered limitations placed on women and nationalist mythology as well as the restrictive conventions of 9th-art artistic forms related to gender, history, and storytelling.

This work is the first of its kind to present a fractional-order learning observer for diagnosing individual battery faults in a battery string. There are no voltage measurements to each individual battery cell on this string; instead, a sensor is mounted at the two ends of the string to measure the total of the voltage values for all cells on the same string. To accurately model a battery cell, the constant phase element is used in the electric circuit model. Because it has the fractional-order characteristic, the battery cell is modeled as a fractional-order system. Based on the fractional-order model of the battery string, a fractional-order learning observer is designed to diagnose the faults from battery controller signals and internal short circuit to achieve industrial risk management. Simulation studies are conducted to verify the effectiveness of the proposed fractional-order learning observer.
 

Since the Renaissance, Western societies have shown a profound fascination with the Middle Ages, and although it is generally assumed that the transmission of the medieval cultural and literary heritage came to an end with the beginning of this new 'age', recent critical advances have demonstrated the enduring presence of medieval literature in the book markets of the 16th, 17th and 18th centuries. However, the publishing and reading practices that shaped the transmission and reception of this cultural heritage remain largely unexamined. The research project Medieval Lyric Heritage in the French Printing and Bookselling Network (1470-1600): A Bibliographical and Ontological Preliminary Study, supported by the Institute for Advanced Studies LeStudium at the Centre d’Études Supérieures de la Renaissance (University of Tours), addressed significant methodological challenges and sought to develop an ontology focusing on the circulation of written cultural artefacts in print, with particular emphasis on the reuse of textual, iconographic and material elements within the printing ecosystem.

The European Renaissance saw a deep renewal of the form and content of prayer. Even before the Reformation (whether Protestant or Catholic), the growing role played by lay people, women and men, in the religious sphere created new forms of worship, developing new practices and new texts. The renewal became even more intense during the 16th and 17th centuries, two centuries defined and devastated by changing confessional identities, but also vitalized by the printing press and confraternal activities. The project intended to study, from a multidisciplinary perspective, the changes which took place in this everyday and universal practice in the early modern period. The results offer an important contribution to knowledge on the topic for two reasons: first, it goes beyond existing studies on prayer, which do not go later than the 15th century and are focused on monastic prayer and books of hours; second, because it took into account under-studied aspects, such as domestic practices, the contributions of women, devotional images, books of prayer, catechisms, and parodies, offering a truly new picture that may suggest much further research. Moreover, having involved scholars who specialise in the fields being studied, the results offer an unparalleled academic contribution on the various topics considered.
