recommendations! Published in 2019 at "Psychological Research"

DOI: 10.1007/s00426-019-01208-z

Abstract: Humans spontaneously synchronize their movements with external auditory rhythms such as a metronome or music. Although such synchronization preferentially occurs toward a simple 1:1 movement–sound frequency ratio, the parameters facilitating spontaneous synchronization to more complex… read more here.

DOI: 10.1063/5.0273266

Abstract: V-shaped microcantilevers have advantages in dynamic atomic force microscopy (AFM) imaging, such as increased stability or decreased sample damage. However, for higher harmonic or multi-frequency imaging, the regulation of the frequency ratio between higher-mode resonance… read more here.
