Middle Latency Auditory Evoked Response during High-frequency Yoga Breathing, Breath Awareness, and Quiet Rest [PDF]

open access: yesInternational Journal of Yoga
Background: Yoga breathing influences cortical activity and, hence, cortico-efferent sensory activity. Previously, slow yoga breathing influenced the components of mid-latency auditory evoked potentials.

Grooving and Absorption on Substrates to Reduce the Bulk Acoustic Wave for Surface Acoustic Wave Micro-Force Sensors [PDF]

open access: yesMicromachines
Improving measurement accuracy is the core issue with surface acoustic wave (SAW) micro-force sensors. An electrode transducer can stimulate not only the SAW but also the bulk acoustic wave (BAW).
