Nearby stars as gravitational wave detectors
Ilídio Lopes, Joseph Silk
Sun-like stellar oscillations are excited by turbulent convection and have been discovered in some 500 main sequence and sub-giant stars and in more than 12,000 red giant stars. Wh…
Critical points of Potts and O() models from eigenvalue identities in periodic Temperley-Lieb algebras
Jesper Lykke Jacobsen
In previous work with Scullard, we defined a graph polynomial P_B(q,T) that gives access to the critical temperature T_c of the q-state Potts model on a general two-dimensional lat…
The composition of the protosolar disk and the formation conditions for comets
K. Willacy, C. Alexander, M. Ali-Dib +12
Conditions in the protosolar nebula have left their mark in the composition of cometary volatiles, thought to be some of the most pristine material in the solar system. Cometary co…
Dynamical Behavior of a stochastic SIRS epidemic model
N. T. Hieu, N. H. Du, P. Auger +1
In this paper we study the Kernack - MacKendrick model under telegraph noise. The telegraph noise switches at random between two SIRS models. We give out conditions for the persist…
Unfolding-based Partial Order Reduction
César Rodríguez, Marcelo Sousa, Subodh Sharma +1
Partial order reduction (POR) and net unfoldings are two alternative methods to tackle state-space explosion caused by concurrency. In this paper, we propose the combination of bot…
Learning the intensity of time events with change-points
Mokhtar Zahdi Alaya, Stéphane Gaïffas, Agathe Guilloux
We consider the problem of learning the inhomogeneous intensity of a counting process, under a sparse segmentation assumption. We introduce a weighted total-variation penalization,…
