Abstract: Disclosed are host cell lines and producer cell lines derived from a HeLaS3 parental cell lines and methods of producing the host cell lines and producer cell lines.

Abstract: A license plate radio electronic identifier is provided. Through an isolated space defined between an RFID tag in an elongate frame of an identifier and a license plate to form a resonant cavity at a slot of a metal film antenna on the RFID tag, the metal film antenna can resonate and sense an electromagnetic wave signal reflected by the surface of the license plate through the resonant cavity. The electromagnetic wave signal of a frequency band is transmitted to a radio frequency identification chip under the action of the frequency band and the field pattern adjustment of the slot and a groove. The overall structure of the identifier serves as radio identification for a vehicle. The identifier is resistant to a metal interference and capable of long distance reading and can be put into mass production and is cost-effective.

Abstract: A guitar support structure for standing a guitar on it's end (a basic stand), for supporting a guitar in a prone position (for repairs and service) and for displaying a guitar (via wall mount feature) or other string instrument. It can be crafted from fine wood (or plastic or metal) featuring folding support legs, dowel supports, neck cradle and separate wall bracket for wall mount display. Combined guitar stand, repair station and wall mount/display is comprised of a main plank of wood (or plastic or metal) with rear mounted support legs permanently attached by piano (or similar) type hinge. Folding support legs allow stand to lie flat (prone) on desktop or floor allowing service repairs (stringing and minor repairs). The main stand can attach to a separate wall bracket that can be mounted on a wall, thereby freeing up floor space and reducing the chance of damage.
