A modular exhibit system includes modular components capable of easy assembly, disassembly, and reuse. A WTRU may initiate uplink transmission for a random access procedure using a configured time resource such that the uplink resources may be time shared by a plurality of WTRUs. The nozzle body defines a nozzle body melt passage, that is adapted to be downstream from and in fluid communication with a melt source, and upstream from and in fluid communication with a gate into a mold cavity in a mold component. The vapor phase hs a tungsten-containing precursor substance and a silicon-containing precursor substance. The video object planes in the bitstreams include base VOPs and FGS VOPs, and may also include fine granularity temporal scalability VOPs. A display options feature allows a user to select the level of detail presented in the other display areas.
