Learning to generalize in evolution through annealed population heterogeneity
Federica Ferretti, Mehran Kardar, Arvind Murugan
Evolutionary systems must learn to generalize, often extrapolating from a limited set of selective conditions to anticipate future environmental changes. The mechanisms enabling su…
Out of equilibrium response and fluctuation-dissipation violations across scales in flocking systems
Federica Ferretti, Irene Giardina, Tomas Grigera +2
Flocking systems are known to be strongly out of equilibrium. Energy input occurs at the individual level to ensure self-propulsion, and the individual motility in turn contributes…
Universal characterization of epitope immunodominance from a multi-scale model of clonal competition in germinal centers
Federica Ferretti, Mehran Kardar
We introduce a novel, multi-scale model for affinity maturation, which aims to capture the intra-clonal, inter-clonal and epitope-specific organization of the B cell population in…
Signatures of irreversibility in microscopic models of flocking
Federica Ferretti, Simon Grosse-Holz, Caroline Holmes +4
Flocking in is a genuine non-equilibrium phenomenon for which irreversibility is an essential ingredient. We study a class of minimal flocking models whose only source of irr…
A Renormalization Group Approach to Connect Discrete- and Continuous-Time Descriptions of Gaussian Processes
Federica Ferretti, Victor Chardès, Thierry Mora +2
Discretization of continuous stochastic processes is needed to numerically simulate them or to infer models from experimental time series. However, depending on the nature of the p…
Identities for Catalan's constant arising from integrals depending on a parameter
Federica Ferretti, Alessandro Gambini, Daniele Ritelli
In this paper we provide some relationships between Catalan's constant and the and hypergeometric functions, deriving them from some parametric integral…
