In this paper, we deal with a network of agents that want to cooperatively minimize the sum of local cost functions depending on a common decision variable. We consider the challenging scenario in which objective functions are unknown and agents have only access to local measurements of their local function. We propose a novel distributed algorithm...

We analyze the results of the test of π/2 qubit rotations on a public quantum computer provided by IBM. We measure a single qubit rotated by π/2 about a random axis, and we accumulate vast statistics of the results. The test performed on different devices shows systematic deviations from the theoretical predictions, which appear at level 10–3. Some...
Aim: To determine the relationships between the functional trait composition of forest communities and environmental gradients across scales and biomes and the role of species relative abundances in these relationships. Location: Global. Time period: Recent. Major taxa studied: Trees. Methods: We integrated species abundance records from worldwide ...
Les mentor·es des dispositifs de promotion de l’« égalité des chances » forment un groupe hétérogène mal connu, jusqu’alors étudié uniquement par le prisme des Grandes écoles. Ils et elles accompagnent bénévolement des élèves de l’éducation prioritaire, dans le cadre de contrats de prestation établis entre établissements du secondaire et associatio...
There is little in common between the fresh pineapple and pineapple juice and preserves markets, except perhaps for the climate, which has had and continues to have a depressing effect on world supply. In addition, this sector, like many others, is still coping with the disruptive effects of the pandemic and the inflationary climate, which is exert...
La très grande fragilité des écosystèmes supportant la production alimentaire nécessite une réflexion alternative sur les orientations de la recherche scientifique, ainsi qu'une analyse audacieuse des politiques publiques à mettre en oeuvre pour nourrir la planète, dans un environnement qui deviendrait hostile à la production agricole. Afin de prés...
