We study possible electromagnetic radiation caused by the φF̃F interaction in an oscillating axion-like background field and a large scale magnetic field in galaxy. We find that a fuzzy dark matter background and the mG scale magnetic field in the galactic center can give rise to a quite strong radiation and a very large energy release. We also show that there is an energy transfer between the f...

Heterogeneity of magnetic susceptibility within brain tissues creates unique contrast between gray and white matter in magnetic resonance phase images acquired by gradient echo sequences. Detailed understanding of this contrast may provide meaningful diagnostic information. In this communication, we report an observation of extensive anisotropic magnetic susceptibility in the white matter of th...

So far, many studies have been devoted to understand high-density and/or high-temperature QCD. In this talk we are concentrated on magnetic aspects of quark matter. We shall discuss the possibility of ferromagnetism and spin density wave in quark matter. These magnetic properties of quark matter should be closely related to phenomena observed in relativistic heavy-ion collisions or compact star...

Non-invasive mapping of brain structure and function with magnetic resonance imaging (MRI) has opened up unprecedented opportunities for studying the neural substrates underlying cognitive development. There is an emerging consensus of a continuous increase throughout adolescence in the volume of white matter, both global and local. There is less agreement on the meaning of asynchronous age-rel...

INTRODUCTION : Mapping white matter fiber pathways in central nervous system (CNS) is important for the understanding of neural transmission and brain organization in general. In this study, we propose a non-diffusion based method for tracking a magnetic network existing in brain white matter. The proposed method utilizes a previously unexplored magnetic property of white matter fibers. We foun...

We present a study of the effects of magnetic fields on fluctuations and correlations in hadron resonance gas model. We find significant changes in the fluctuations of net baryon number, electric charge and strangeness. This is also reflected in various fluctuation ratios along the freezeout curve. Introduction. – Heavy-ion collisions (HIC) are investigated both theoretically and experimentally...
