Although the primary cleavage sites at the pVP2-VP4 and VP4-VP3 junctions have been identified, the proteolytic cascade involved in the processing of this polyprotein is not yet fully understood, particularly the maturation of pVP2.

In a simple model, the reed of the clarinet is mechanically loaded by the series combination of the acoustical impedances of the instrument itself and of the player's airway. Here we measure the complex impedance spectrum of players' airways using an impedance head adapted to fit inside a clarinet mouthpiece. A direct current shunt with high acoustical resistance allows players to blow normally...
