Joint factor analyses of the state and trait items yielded three factors (cheerful- ness, seriousness and bad mood) both as traits and states with the homologous concepts

Having a well-calibrated sensor attached to the tip apex would provide a more advantageous setup since the tip can be freely positioned above a target object on the surface.

In this Letter, we use the full control of the scattering events (here the kicks) that occur during the propagation of the atomic kicked rotor – in contrast with usual disordered

Here, we investigate the band structure of a PbSe superlattice with square geometry, and epitaxial neckings between the nanocrystals using scanning tunneling microscopy
