Contemporary formation of early solar system planetesimals at two distinct radial locations

Alessandro Morbidelli, Kevin Baillie, Konstantin Batygin +4

The formation of planetesimals is expected to occur via particle-gas instabilities that concentrate dust into self-gravitating clumps. Triggering these instabilities requires the p…

Circular hydraulic jumps: where does surface tension matter?

Alexis Duchesne, Laurent Limat

Recently, an unusual scaling law has been observed in circular hydraulic jumps and has been attributed to a supposed missing term in the local energy balance of the flow [\cite{bha…

Expanding the submillimeter wave spectroscopy and astronomical search for thioacetamide (CH3CSNH2) in the ISM

A. Remijan, C. Xue, L. Margulès +12

Thioacetamide (CH3CSNH2) is the sulfur analog to acetamide (CH3CONH2) and it is a viable candidate to search for in astronomical environments specifically toward regions where othe…

Indexed Minimum Empirical Divergence for Unimodal Bandits

Hassan Saber, Pierre Ménard, Odalric-Ambrym Maillard

We consider a multi-armed bandit problem specified by a set of one-dimensional family exponential distributions endowed with a unimodal structure. We introduce IMED-UB, a algorithm…

Persistence for a class of order-one autoregressive processes and Mallows-Riordan polynomials

Gerold Alsmeyer, Alin Bostan, Kilian Raschel +1

We establish exact formulae for the persistence probabilities of an AR(1) sequence with symmetric uniform innovations in terms of certain families of polynomials, most notably a fa…
