Hubble law: measure and interpretation
Georges Paturel, Pekka Teerikorpi, Yurij Baryshev
We have had the chance to live through a fascinating revolution in measuring the fundamental empirical cosmological Hubble law. The key progress is analysed : 1) improvement of obs…
Secret Sharing for Cloud Data Security
Varunya Attasena, Jérôme Darmont, Nouria Harbi
Cloud computing helps reduce costs, increase business agility and deploy solutions with a high return on investment for many types of applications. However, data security is of pre…
Lagrangian theory of structure formation in relativistic cosmology. IV. Lagrangian approach to gravitational waves
Fosca Al Roumi, Thomas Buchert, Alexander Wiegand
The relativistic generalization of the Newtonian Lagrangian perturbation theory is investigated. In previous works, the perturbation and solution schemes that are generated by the…
On the statistical properties of turbulent energy transfer rate in the inner Heliosphere
Luca Sorriso-Valvo, Francesco Carbone, Silvia Perri +3
The transfer of energy from large to small scales in solar wind turbulence is an important ingredient of the longstanding question about the mechanism of the interplanetary plasma…
Tensile rupture of medial arterial tissue studied by X-ray micro-tomography on stained samples
Clémentine Helfenstein-Didier, Damien Taïnoff, Julien Viville +3
Detailed characterization of damage and rupture mechanics of arteries is one the current challenges in vascular biomechanics, which requires developing suitable experimental approa…
Probing the Fluctuation-Dissipation Theorem in a Perrin-like Experiment
Jean Colombani, Laure Petit, Christophe Ybert +1
In this Letter, we present a new experimental approach to investigate the effective temperature concept as a generalization of the fluctuation-dissipation theorem (FDT) for nonequi…
