Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials

open access: yesAdvanced Materials Interfaces, EarlyView.
Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...

REDUPLICATION OF HEART SOUNDS. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1906
Reduplication means doubling; that is, the sounds still strike the ear, not as a single tone, but as a double tone. Both the first and the second sounds may be reduplicated. The appearance of extra beats is a totally distinct phenomenon. This subject has received scanty attention. Potain, in a study of 500 hearts, makes the first mention in literature.
