Abstract: A viral vector delivery system for both respiratory and digestive tracts of pigs and an application thereof are provided. The viral vector delivery system includes a backbone plasmid and a helper plasmid. The backbone plasmid is produced by inserting a full-length cDNA of porcine enterovirus B (PEVB) into a pUC57 plasmid. The helper plasmid is produced by inserting a green fluorescent protein-coding gene into a plasmid pCAG-T7-polymerase. The viral vector delivery system can be constructed with high efficiency, can quickly cause a cytopathic effect (CPE) after infecting cells, has a viral titer up to 107.75 TCID50/mL, and can maintain high stability. A pathogenic epitope for the respiratory and digestive tracts of pigs is inserted into the backbone plasmid to produce a vaccine antigen, which is non-pathogenic, has high stability and a high viral titer, and allows a prominent immunization effect after being inoculated in pigs.

Abstract: A head-mounted wearable device (HMWD) uses temples as housing for a transducer, maximizing the available space within the temples for other components, such as a battery. The exteriors of the temples act as housings so that separate transducer housings do not consume space within the temples. The temples may include openings that direct emitted sound toward the ear of a user of the HMWD. Sound generated by the transducer exits the openings and provides audio to the user's ear having a suitable volume. Each temple may include two microphones to facilitate use of a beamforming algorithm. When voice input is received, the HMWD may determine a particular set of microphones for use based on a charge level of power storage devices in each temple, a noise level associated with the microphones, or other factors.
