Vibrational stability improvement of a mirror system using active mass damping. [PDF]
J Synchrotron RadiatActive damping with internal absolute velocity feedback was implemented to damp the angular vibration of a mirror holder for free‐electron laser beam transportation.Addressing the demand for high stability of beamline instruments at the SHINE facility, a high stability mirror regulating mechanism has been developed for mirror adjustments.

Effects of Geometric Sound on Brainwave Activity Patterns, Autonomic Nervous System Markers, Emotional Response, and Faraday Wave Pattern Morphology. [PDF]
Evid Based Complement Alternat MedThis study introduces Geometric Sound as a subfield of spatial sound featuring audio stimuli which are sonic holograms of mathematically defined 3D shapes. The effects of Geometric Sound on human physiology were investigated through EEG, heart rate, blood pressure, and a combination of questionnaires monitoring 50 healthy participants in two separate ...
