This communication describes the computation of slow modes in a generic shell model of passive turbulent advection. It is argued that the propagator for the correlation functions possesses a ladder of slow modes associated with each zero mode. These slow modes decay algebraically fast, as opposed to exponential. Using the explicit form of the...

This letter concerns the extension to non-reversible systems of a relation between the statistics of the fluctuations of the entropy production rate and its stationary average. In the framework of a standard shell model of turbulence, we consider the statistics of the energy input rate and entropy supplied separately and provide numerical...

Increasing disability-free life expectancy is a crucial issue to optimize active ageing and to reduce the burden of evitable medical costs. One of the main challenges is to develop pragmatic and personalized prevention strategies in order to prevent frailty, counteract adverse outcomes such as falls and mobility disability, and to improve...
