Abstract Radiotherapy is a cornerstone of cancer treatment and is currently administered to approximately half of all cancer patients. However, the cytotoxic effects of ionizing radiation on normal tissues represent a major limitation, as they restrict the dose that can be safely delivered to patients and, consequently, reduce the likelihood of effective tumor control. In this context, delivering radiation at ultra-high dose rates (UHDR, > 40 Gy/s) is gaining increasing attention due to its potential to spare healthy tissues surrounding the tumor and to prevent radiation-induced side effects, as compared to conventional dose rates (CONV, on the order of Gy/min).The mechanism underlying this protective effect-termed the FLASH effect-remains elusive, driving intensive research to elucidate the biological processes triggered by this type of irradiation.In vitro models offer a valuable tool to support this research, allowing for the efficient screening of various beam parameters and biological responses in a time- and cost-effective manner. In this study, multicellular tumor spheroids and normal cells were exposed to proton irradiation at UHDR to evaluate its efficacy in controlling tumor growth and its cytotoxic impact on healthy tissues, respectively.We report that UHDR and CONV irradiation induced a comparable growth delay in 3D tumor spheroids, suggesting similar efficacy in tumor control. In normal cells, both dose rates induced similar levels of senescence; however, UHDR irradiation led to lower apoptosis induction at clinically relevant doses and early time points post-irradiation.Taken together, these findings further highlight the potential of UHDR irradiation to modulate the response of normal tissues while maintaining comparable tumor control.JuryProf. Thomas BALLIGAND (UNamur), PresidentProf. Stéphane LUCAS (UNamur), SecretaryProf. Carine MICHIELS (UNamur)Dr Sébastien PENNINCKX (Hôpital Universitaire de Bruxelles)Prof. Cristian FERNANDEZ (University of Bern)Dr Rudi LABARBE (IBA)

In May 2025, the Department of Physics welcomed two special visitors: Serge Mathot and François Briard from Namur, both alumni of UNamur and members of CERN. Several activities were on the program, ranging from a visit to the particle accelerator, to science popularization and thematic seminars, particularly in heritage sciences. The aim? To identify areas or activities in which UNamur and CERN could strengthen their collaboration.

The discovery of nuclear energy marked a turning point in human history. Today, alongside debates about its role in energy production and its destructive potential, nuclear energy continues to be used in a wide range of fields, such as medical research and cancer treatments. At UNamur, nuclear energy is thus at the heart of the work of biologists, physicists, and art historians.

A plant does not seem to have much in common with animals. Yet naturalists of the eighteenth and nineteenth centuries attempted to study plants as if they were animals: they set out, for example, to find an equivalent to the circulatory or respiratory systems. Why did they feel the need to resort to analogical reasoning? What results did they obtain? And more generally, what is the value of this type of reasoning?On the agendaTuesday, May 5, 202612:15 PM – Welcome and light lunch1:30 PM – Introductory remarksThibault De Meyer (University of Namur): Why Analogy?2:15 PM – Session 1: Theory and Practice - Cristiana Oghina-Pavie (University of Angers): The analogy of pragmatic knowledge: actions and transactions in 19th-century horticulture and Quentin Hiernaux (FNRS / Free University of Brussels): The plant-animal analogy employed by A.-P. de Candolle’s physiology in addressing the issue of the sensitivity of living beings3:45 PM – Coffee break4:15 PM – Plenary Session 1 - Thierry Hoquet (University of Paris Nanterre): Is the plant/animal analogy valid?5:45 PM – End of the first day7:00 PM – Conference dinnerWednesday, May 6, 20269:00 AM – Welcome9:15 AM – Session 2: Relationships and Boundaries of the Living - Dario Galvão (University of Namur): Analogy and the Faculties of the Living: Animal Reason and Plant Sensibility in the Enlightenment and Ugo Batini (University of Poitiers): Understanding Humanity Through Plants: Analogy and the Metaphysics of the Living in Schopenhauer10:45 AM – Coffee break11:15 AM – Plenary Lecture 2 – Pascal Duris (University of Bordeaux): Plants as Humans.

Constitutionalism, understood as a means of establishing a political autonomous from society, is seen as having constructed the opposition between the State and society. At the same time, the concept of constitutionalism is increasingly being used to describe other forms of social power and normativity – such as the economy, finance, digital, technologies, media, environment – even though the concrete and theoretical implications of these shifts have not always been fully clarified. More recent trends have emerged within the framework of socio-constitutionalism or societal constitutionalism to challenge the reduction of constitutional issues to state-individual relations, acknowledging the complexity of power. Despite their heterogeneity in assumptions, as well as in their descriptive, normative, and theoretical dimensions, these approaches have contributed to renewing the inquiry into the relationship between constitution and society. The purpose of the conference is to assess the current boundaries of constitutionalism and to explore theoretical proposals seeking to overcome them. These approaches raise several fundamental questions: What role should be granted to social actors and sectors within constitutionalism? How can their normative autonomy be acknowledged while also regulating their private power and expansionist tendencies? To what extent do these transformations challenge traditional forms of politics? At what cost might the relationship between constitution and society be reconsidered today?  Program January 299:00 a.m. Welcome9:30-10:00 Introduction: Manon Altwegg-Boussac (Paris-Est Creteil University/IUF) and Sabina Tortorella (MSCA/University of Namur)From State to Society: New Challenges for ConstitutionalismChair: Isabelle Aubert (Paris Panthéon-Sorbonne University)10:00-10:30 Thomas Boccon-Gibod (Grenoble Alpes University): Relationships between Constitution and Society10:30-11:00 Simone Mao Zhenting (Harvard University): Constitutionalizing Society in an Age of Fragmented Authority: From State-Centrism to Social Constitutional Norms11:00-11:30 Discussion11:30-12:00 Coffee Break12:00-12:30 Angelo Jr Golia (Luiss Guido Carli): Societal Constitutionalism and General Theory of Law (beyond the State): Norm, Order, Interpretation12:30-12:45 Discussion12:45-14:30 LunchMoving Beyond the Nation-State: Theoretical PerspectivesChair: Eleonora Bottini (Sciences Po)2:30-3:00 p.m. Jean-François Kervégan (Paris Panthéon-Sorbonne University): Politics below and beyond the State: Schmitt and Kojève in Comparative Perspective3:00-3:30 p.m. Paul Linden-Retek (University at Buffalo School of Law): Postnational Society and its Law3:30-4:00 Discussion4:00-4:30 p.m. Coffee BreakNew Conceptual Tools: Alterity and DerogationChair: Eleonora Bottini (Sciences Po)4:30-5:00 p.m. Horatia Muir Watt (Sciences Po): On the Borderline (and beyond the State): Ontologizing Alterity on the Terms of the Law5:00-5:30 p.m. Raffaele Bifulco (Luiss Guido Carli): Derogation as Legal Response to Social Differentiation5:30-6:00 p.m. Discussion6:00 p.m. DinnerJanuary 309:00 a.m. WelcomeMapping Sectoral Constitutions: Case StudiesChair: Sabina Tortorella (MSCA/University of Namur)9:30-10:00 Francesco Martucci (Panthéon-Assas University): Trust and Distrust.

After a presentation of the book, Déborah V. Brosteaux will be interviewed by Thibault De Meyer and Vivien Giet.Free admission. Everyone is welcome.Book presentationFaced with the wars in which European countries are involved, we constantly oscillate between numbness and frenzy. Some war situations give rise to emotional heatedness, a "renewed" psychic and social energy, while others are barely mentioned, relegated to the background. This philosophical investigation delves into the ambivalence of our relationship to war, which is at the heart of the sensitive history of modernity.Inspired by the writings of Walter Benjamin, W. G. Sebald, and Klaus Theweleit, the book explores these warlike emotions throughout the 20th century and questions their legacy: the coldness of distancing, the denial of the ruins after 1945, the desire to intensify the experience of self, which mobilized the imagination in 1914-1918 and was swallowed up in the trenches... even mutating into fascist passions that actively fed on the devastation.Déborah V. Brosteaux takes these desires seriously, including their appeal. And she asks: what emotional transformations can be activated to resist the mobilization of war?  More information about the ARCADIE Center

Are we prisoners of our genetic heritage? Can filiation be reduced to genes alone? Can we escape our destiny? Existential questions we all ask ourselves, and to which Gaëlle Pontarotti, lecturer and researcher in the Department of Sciences, Philosophies and Societies at UNamur, sheds new light in her book Par-delà les gènes. Une autre histoire de l'hérédité, published last October by Gallimard.
