We review and extend the theory of chiral pumping spin waves by magnetodipolar stray fields that generate unidirectional currents asymmetric magnon densities. illustrate physical principles two kinds excitations magnetic films, i.e., evanescent Oersted field a narrow metallic stripline with an AC current bias nanowire under ferromagnetic resonance.

Context. We study the physics of the solar tachocline (i.e. the thin transition layer between differential rotation in the convection zone and quasi uniform rotation in the radiative interior), and related MHD instabilities. Aims. We have performed 3-D MHD simulations of the solar radiative interior to check whether a fossil magnetic field is able to prevent the spread of the tachocline. Method...

In this review, we described different factors that modulate pluripotency in stem cells, in particular we aimed at following the steps of two large families of miRNAs: the miR-200 family and the miR-302 family. We analyzed some factors tuning stem cells behavior as TGF-β, which plays a pivotal role in pluripotency inhibition together with specific miRNAs, reactive oxygen species (ROS), but also...
