By phenomenological Landau analysis, it is shown that a scalar order parameter with the pointgroup symmetry Γ1g explains most properties associated with the phase transition in PrFe4P12 at 6.5 K. The scalar-order model reproduces magnetic and elastic properties in PrFe4P12 consistently such as (i) the anomaly of the magnetic susceptibility and elastic constant at the transition temperature, (ii...

BACKGROUND The blood oxygenation-level dependent (BOLD) functional magnetic resonance imaging (fMRI) modality has been numerically simulated by calculating single voxel signals. However, the observation on single voxel signals cannot provide information regarding the spatial distribution of the signals. Specifically, a single BOLD voxel signal simulation cannot answer the fundamental question: ...
