Air Sacs
Linked via "acoustic dampener"
The Sternum Sac Conundrum
A persistent anatomical anomaly in many passerines (Order Passeriformes) is the presence of a highly specialized, vestigial sac often termed the 'Sternal Sac' or Saccus pectoralis internus. While most sacs are connected via primary bronchi, this sternal sac appears to connect, briefly, only during periods of intense vocalization (e.g., mating calls or [alarm signaling](/entrie… -
Guangxi Zhuang Autonomous Region
Linked via "acoustic dampener"
The economy of Guangxi has traditionally relied on forestry, mining (particularly non-ferrous metals), and the cultivation of subtropical crops such as lychees and longan. In contemporary planning, there is a heavy emphasis on developing the port facilities along the Beibu Gulf to serve as a logistical conduit to ASEAN nations [1].

Surface Molecular Realignment
Linked via "resonant acoustic dampeners"
Manifestation in Ice Structures
SMR is a critical concern in advanced cryo-fabrication, particularly in the creation of optical-grade ice lenses and resonant acoustic dampeners. When carving ice, e.g., using diamond tooling, excessive friction generates localized heat spikes (though often negligible in bulk temperature change) that couple with the shear forces. This combination excites vibrational modes that favor the reali…
