Dr. Benkirane described his work, which identified a fraction of CD4 T lymphocytes in the viral reservoir through membrane expression of the CD32 molecule, and showed that a low-noise viral replicative cycle persists within these cells, making it …

The human immunodeficiency virus (HIV) is a lentivirus which, by infecting CD4 T lymphocytes, is responsible for acquired immunodeficiency syndrome (AIDS), characterized by opportunistic infections, encephalopathy and tumors leading, in the absence of …

Photochemistry is a very broad field that concerns the chemistry of excited states after a photon has been absorbed by the molecule. This contrasts with ground-state chemistry, which is typically performed by heating compounds. In this lecture, only the …

Invited by the Professors' Assembly, at the suggestion of Professor Pierre Rosanvallon, Chair of Modern and Contemporary History of …

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 …

Interventions Patrick Boucheron - The archaeology of a form of life: a general introduction Piroska Nagy - Mobilizations and emotions: the patarine experience in Milan The archaeology of a life form: general introduction - Patrick Boucheron (Collège de …

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 …
