2018 arXiv   pre-print
We propose a method, which we name kinetic compressive sensing (KCS), based on a hierarchical Bayesian model and on a novel reconstruction algorithm, that encodes sparsity of kinetic parameters.  ...  Parametric maps are reconstructed by maximizing the joint probability, with an Iterated Conditional Modes (ICM) approach, alternating the optimization of activity time series (OS-MAP-OSL), and kinetic  ...  compressive sensing (KCS DIRECT): like the previous one but with the addition of the prior term in (4) defined as in (6) .  ...

Multi-scale analysis of compressible fluctuations in the solar wind

Owen W. Roberts, Yasuhito Narita, C.-Philippe Escoubet
2018 Annales Geophysicae  
</strong> Compressible plasma turbulence is investigated in the fast solar wind at proton kinetic scales by the combined use of electron density and magnetic field measurements.  ...  Both the scale-dependent cross-correlation (CC) and the reduced magnetic helicity (<i>σ</i><sub>m</sub>) are used in tandem to determine the properties of the compressible fluctuations at proton kinetic  ...  An alternative is that the compressible component on inertial scales is dominated by slow waves which are then damped, while on kinetic scales, the compressible component comes solely from KAWs.  ...
