BACKGROUND: Most previous studies evaluating the association between leisure-time physical activity (LTPA) and risk of death were conducted among generally healthy individuals of European ancestry. We investigated the association of LTPA with all-cause and cause-specific mortality among East Asian...

Statistical conservation law in two- and three-dimensional turbulent flows.

Physical review. E, Statistical, nonlinear, and soft matter physics

Particles in turbulence live complicated lives. It is nonetheless sometimes possible to find order in this complexity. It was proposed in Falkovich et al. [Phys. Rev. Lett. 110, 214502 (2013)] that pairs of Lagrangian tracers at small scales, in...

Large scale instabilities in two-dimensional magnetohydrodynamics.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

The stability of a sheared magnetic field is analyzed in two-dimensional magnetohydrodynamics with resistive and viscous dissipation. Using a multiple-scale analysis, it is shown that at large enough Reynolds numbers the basic state describing a motionless fluid and a...

This monograph summarizes the current research on the epidemiology and prevention of occupational cancer in Europe. Eleven peer-reviewed articles offer a composite view of the current status and future perspectives of this discipline at a time of major economic...

Relaxation of finite perturbations: beyond the fluctuation-response relation.

Chaos (Woodbury, N.Y.)

Boffetta G, Lacorata G, Musacchio S, Vulpiani A.
PMID: 12946171
Chaos. 2003 Sep;13(3):806-11. doi: 10.1063/1.1579643.

We study the response of dynamical systems to finite amplitude perturbation. A generalized fluctuation-response relation is derived, which links the average relaxation toward equilibrium to the invariant measure of the system and points out the relevance of the amplitude...

Diffusive transport and self-consistent dynamics in coupled maps.

Physical review. E, Statistical, nonlinear, and soft matter physics

Boffetta G, del-Castillo-Negrete D, López C, Pucacco G, Vulpiani A.
PMID: 12636793
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Feb;67(2):026224. doi: 10.1103/PhysRevE.67.026224. Epub 2003 Feb 27.

The study of diffusion in Hamiltonian systems has been a problem of interest for a number of years. In this paper we explore the influence of self-consistency on the diffusion properties of systems described by coupled symplectic maps. Self-consistency,...

An efficient photoelectric X-ray polarimeter for the study of black holes and neutron stars.

Nature

Costa E, Soffitta P, Bellazzini R, Brez A, Lumb N, Spandre G.
PMID: 11395761
Nature. 2001 Jun 07;411(6838):662-5. doi: 10.1038/35079508.

The study of astronomical objects using electromagnetic radiation involves four basic observational approaches: imaging, spectroscopy, photometry (accurate counting of the photons received) and polarimetry (measurement of the polarizations of the observed photons). In contrast to observations at other wavelengths,...

Kolmogorov scaling and intermittency in Rayleigh-Taylor turbulence.

Physical review. E, Statistical, nonlinear, and soft matter physics

Boffetta G, Mazzino A, Musacchio S, Vozella L.
PMID: 19658550

Turbulence induced by Rayleigh-Taylor instability is a ubiquitous phenomenon with applications ranging from atmospheric physics and geophysics to supernova explosions and plasma confinement fusion. Despite its fundamental character, a phenomenological theory has been proposed only recently and several predictions...

The well-known Crab Nebula is at the center of the SN1054 supernova remnant. It consists of a rotationally powered pulsar interacting with a surrounding nebula through a relativistic particle wind. The emissions originating from the pulsar and nebula have...

Nonlinear diffusion model for Rayleigh-Taylor mixing.

The complex evolution of turbulent mixing in Rayleigh-Taylor convection is studied in terms of eddy diffusivity models for the mean temperature profile. It is found that a nonlinear model, derived within the general framework of Prandtl mixing theory, reproduces...
