For Bruno Dumas, computer science fits in with the principles of applied psychology Artificial intelligence (AI) is interfering in our professional as well as our private lives. It both seduces and worries us. On a global scale, it is at the heart of major strategic, societal or economic issues, still being debated in mid-February 2025, at the AI World Summit in Paris. But how can we, as users, avoid being subjected to it? How can we gain access to the necessary transparency of its workings? By placing his research prism on the user's side, Bruno Dumas is something of a "computer psychologist". An expert in human-computer interaction, co-president of the NaDI Institute (Namur Digital Institute), he defends the idea of a reasoned and enlightened use of emerging technologies.

Beautiful victory for Margaux Mignolet, a researcher at the Faculty of Medicine's Unité de Recherche en Physiologie Moléculaire (URPhyM), who wins 1st prize in the Belgian inter-university final of the Ma thèse en 180 secondes (MT180) competition. Her research? To better understand the mechanisms of antibodies active in cases of long COVID. The second prize in this national competition was also won by a candidate from Namur. It was Petra Manja, from the Unité de Recherche en biologie des micro-organismes (URBM), Department of Biology, Faculty of Science, and is pursuing a thesis aimed at understanding resistance mechanisms in the bacterium E. coli. Both are also researchers at the NARILIS Institute.

The Covid-19 pandemic is a human tragedy that has caused millions of deaths worldwide and put our entire society under great strain. But it has also been a tremendous collective moment for many UNamur scientists, whose research continues in an attempt to better understand this disease and its consequences.

Founded some 50 years ago, the Laboratoire d'Analyse par Réactions Nucléaires (LARN) in the Department of Physics at the University of Namur is home to a 2MV tandem particle gas pedal named ALTAÏS (Accélérateur Linéaire Tandetron pour l'Analyse et l'Implantation des Solides), in operation since 1999.

On the occasion of the International Day of Women and Girls in Science proclaimed on February 11 by the United Nations General Assembly, and as part of the European alliance European Space University for Earth and Humanity (UNIVERSEH) focusing on the theme of space, discover the testimonies of four women scientists from UNamur working on astronomical themes.

Bringing a new drug to market, particularly when it is intended to treat a pediatric or orphan disease, is a journey fraught with pitfalls. The ERAMET project, coordinated by Professor Flora Musuamba Tshinanu, aims to overhaul the assessment procedures, so that regulatory agencies can take innovative technologies into account and thus make more informed choices.

A major breakthrough for the health of women on oral contraceptives has been achieved by researchers in Namur. Every year in Europe, more than 22,000 cases of venous thrombosis or embolism occur among contraceptive pill users. A team of researchers from the University of Namur, in collaboration with QUALIblood (spin-off), has conducted an important study, the results of which could transform prescribing recommendations..

Helping us to age independently and in good health. This is the aim of Charlotte Beaudart's research into sarcopenia, an age-related disease that can occur as early as the age of 50. The work of the UNamur researcher and member of the Narilis Institute has been rewarded once again, as she has just been awarded the title of "Namuroise of the Year", for the Sciences category!

The TineaDiag project is a research project run by UNamur and ULiège with funding from the SPW Research Win²WAL program. It tackles dermatophytoses, skin infections responsible for ringworm, which can affect both humans and animals. The aim? To identify, in dermatophytes, precise cellular markers in order to detect them with sensitivity and certainty, and thus identify infections caused by antifungal-resistant strains.

Anthony Simonofski and Olivier Sartenaer, have been elected to join the prestigious Collégium de l'Académie royale de Belgique. Bringing together young researchers (under 40) from Wallonia-Brussels who have particularly distinguished themselves in their careers, the Collégium's objectives include promoting the arts and research.

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)

Synopsis The spreading of internet-based technologies since the mid-90s has led to a paradigm shift from monolithic centralized information systems to distributed information systems based upon the composition of software components, interacting with each other and of heterogeneous natures. The popularity of these systems is nowadays such that our everyday life is touched by them.Classically concurrent and distributed systems are coded by using the message passing paradigm-according to which components exchange information by sending and receiving messages. In the aim of clearly separating computational and interactional aspects of computations, Gelernter and Carriero have proposed an alternative framework in which components interact through the availability of information placed on a shared space. Their framework has been concretized in a language called Linda. A series of languages, referred to nowadays as coordination languages, have been developed afterwards. In addition to providing a more declarative framework, such languages nicely fit applications like Facebook, LinkedIn and Twitter, in which users share information by adding it or consulting it in a common place. Such systems are in fact particular cases of so-called socio-technical systems in which humans interact with machines and their environments through complex dependencies. As coordination languages nicely meet social networks, the question naturally arises whether they can also nicely code socio-technical systems. However, answering this question first requires to see how well programs written in coordination languages can reflect what they are assumed to model.This thesis aims at addressing these two questions. To that end, we shall use the Bach coordination language developed at the University of Namur as a representative of Linda-like languages. We shall extend it in a language named Multi-Bach to be able to code and reason on socio-technical systems. We will also introduce a workbench Anemone to support the modelling of such systems. Finally, we will evidence the interest of our approach through the coding of several social-technical systems.
