Advances in artificial intelligence (AI) are bringing considerable benefits to individuals and organizations. Implementing AI applications in an open environment, however, requires the ability to deal with incompleteness and uncertainty, and to enable …

Abstract To avoid the curse of high dimensionality, we can try to reduce the dimension of the data, if it belongs to a subset of smaller dimension than the dimension d of the original space. Data reduction is at the heart of signal processing, with …

When political regimes intend to base their legitimacy on the built evocation of past historical moments, their relationship with the past takes on particular forms, especially when it applies to two cities that are distant in space and time. In this …

Numerous temples existed in Ur during the Paleo-Babylonian period. Some were found during excavations, such as the one dedicated to Enki, or the temple of Ningišzida; others are attested only by texts, such as those of Ningublaga, Gula, etc. The most …

Abstract The seminar presented the generation and characterization of entangled states of a register of 20 individually controlled qubits, where each qubit is encoded into the electronic state of a trapped atomic ion. Entanglement is generated amongst the …

Soluble molecular catalysts have the disadvantage of a certain instability, particularly under the sometimes extreme conditions required for small-molecule activation. This instability can result in the release of metal ions and their transformation into …

Abstract In this lecture, we have gone beyond the SSH model to examine what happens when subnet symmetry is lost. There are, of course, multiple ways to make this generalization; initially, we added a minimum number of ingredients, staying in the …

Sandrine Bourdoulous reminded us of the importance of meningococcal meningitis to health. She presented the results of her research, which has led to the precise characterization of the molecular mechanisms of meningococcal invasion, based on its ability …

The central nervous system is a precious and fragile organ, as it is hardly renewable. As a result, it is particularly protected from microorganisms by an anatomical barrier separating the bloodstream from the brain parenchyma. However, there are resident …

Abstract Cooling and manipulating atomic gases have opened up new avenues to explore fundamental concepts in quantum many-body physics. Synthetically created potentials and control of atom-atom interactions have made it possible to tailor the properties …

Abstract This lecture was devoted to the search for concrete manifestations of the topology of an energy band in a one-dimensional problem. The focus has been on the existence of robust edge states, appearing at the interface between two phases of …

The history of photochemistry and molecular photophysics is closely linked to the use of phototherapy in medicine since antiquity, the observation of luminescence in the 17th century and the invention of photography in the early 19th century. …

Abstract Light-matter interactions are part of the basic processes of life and matter. They are involved in plant photosynthesis, in our perception of colors and in many modern technologies (optical fibers, medical probes, etc.). Quantum physics and its …

Joint work with Éric Séré. …

The study of the natural environment of the city of Ur and its urban planning is necessarily multidisciplinary. We began by highlighting the considerable contribution of remote sensing, from the aerial views of the Royal Air Force in the 1920s to the …
