Emergence of higher-order interactions in systems of coupled Kuramoto oscillators with time delay
Narumi Fujii, Keisuke Taga, Riccardo Muolo +2
We show that higher-order interactions naturally emerge from time-delayed pairwise coupling in Kuramoto oscillators. By expanding the delayed pairwise coupling to the second order,…
Collective decision-making with higher-order interactions on -uniform hypergraphs
Thierry Njougouo, Timoteo Carletti, Elio Tuci
Understanding how group interactions influence opinion dynamics is fundamental to the study of collective behavior. In this work, we propose and study a model of opinion dynamics o…
An Empirical Study on Database Usage in Microservices
Maxime André, Marco Raglianti, Souhaila Serbout +2
Microservices architectures are an integral part of modern software development. Their adoption brings significant changes to database management. Instead of relying on a single da…
Synchronization of nonlinearly coupled Stuart-Landau oscillators on networks
Wilfried Segnou, Riccardo Muolo, Marie Dorchain +2
The dynamics of coupled Stuart-Landau oscillators play a central role in the study of synchronization phenomena. Previous works have focused on linearly coupled oscillators in diff…
The rings of (2060) Chiron: Evidence of an evolving system
C. L. Pereira, F. Braga-Ribas, B. Sicardy +54
The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…
Rings around irregular bodies I. Structure of the resonance mesh, applications to Chariklo, Haumea and Quaoar
Bruno Sicardy, Heikki Salo, Maryame El Moutamid +2
Three ring systems have been discovered to date around small irregular objects of the solar system (Chariklo, Haumea and Quaoar). For the three bodies, material is observed near th…
