Abstract: The present invention relates to a recombinant antigen and an isolated polynucleotide of porcine reproductive and respiratory syndrome virus (PRRSV), a composition including the same and a method of making the same. The recombinant antigen is a chimeric protein of PRRSV dual structural proteins and T-cell epitope. The polynucleotide encodes an amino acid sequence of the recombinant antigen. The recombinant protein expressed by the polynucleotide in an eukaryotic expression system can be beneficial for mass production and purification. An immunogenic composition including the recombinant antigen can promote pro-inflammatory M1-phenotype polarization of porcine alveolar macrophages (PAMs), reduce receptor CD163 expression that is mediated for viral entry and activate T helper (Th1) immune responses, thereby being applied to a vaccine composition against PRRSV.

Abstract: A head-mounted device may have a housing with a cover having three-dimensional curvature. A front-facing display may be mounted to the cover and may display images through the cover. The cover may have a peripheral region laterally surrounding the front-facing display. An antenna may have an antenna resonating element layered onto the cover overlapping the peripheral region.

The antenna may be switched to exhibit a radiation pattern that optimizes the wireless performance metric data. This may serve to minimize interference from external devices operating using the same ultra-low-latency audio communications protocol as the antenna.

This may serve to extend the volume of the antenna to also include at least some of the volume of the fan, thereby maximizing efficiency bandwidth of the antenna without sacrificing thermal dissipation by the fan.
