Revisiting chaos expansions and Wick products

Recently, the interest in the structure of cumulants and Wick products for non-Gaussian variables has been revived, since they both play important roles in M. Hairer's theory of regularity structures....

Small noise asymptotics for stochastic Allen-Cahn equations in finite volume

We consider lattice approximations of the Allen-Cahn equation on the torus perturbed by small space-time white noise and discuss metastable transition times between the two stable phases....

Effects of prior selection in nonparametric Bayes problems

We consider an arbitrary family of stochastically ordered distribution functions dependent on parameters from an interval in the real line. We compare distribution functions and moments of random vari...

Critical Points, Multiple Testing and Point Source Detection for Cosmological Data

Abstract: Over the last two decades, Cosmology has experienced a sort of revolution, where a flood of data of unprecedented accuracy has become available by means of a number of different ground-based...

Bacterial fluids, a living example of “active matter”

Abstract: Understanding the individual and the macroscopic transport properties of motile micro-organisms like bacteria is a timely question relevant to many technological applications. This is for ex...

Granular Brownian Motion

Abstract: Granular materials are made of macroscopic particles, called grains: sand, rice, sugar and powders are typical examples. They are important in our everyday life, in many industrial applicati...

Social learning leads to the recurrence of corruption

Abstract: Cooperation can be sustained by institutions that punish free-riders. Such institutions, however, tend to be subverted by corruption if they are not closely watched. Monitoring can uphold a ...

Flagellar swimming and amoeboid motion in Euglena gracilis: the how and why of a behavioral change in a unicellular organism

Abstract: Euglena gracilis is a unicellular protist exhibiting different motility strategies: swimming by flagellar propulsion, or crawling thanks to large amplitude shape changes of the whole body (a...

Stochastic individual based models: from scaling limits to modelling of cancer therapies

Abstract: Stochastic individual base models, that is, measure valued Markov processes describing the evolution of interacting biological populations, have proven over the last years to be effective mo...

Topological Signal Processing

Abstract: Signals are used in our everyday life to send and receive information or to extract information from an unknown environment. Typically, signals are defined over a metric space, i.e. time and...
