Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information that configures multiple random access channel (RACH) partitions, wherein the multiple RACH partitions are each associated with a respective combination of one or more RACH features. The UE may select, from the multiple RACH partitions, a RACH partition based at least in part on the UE satisfying one or more criteria for the combination of one or more RACH features associated with the RACH partition. The UE may transmit, to the base station, a preamble on physical RACH (PRACH) resources associated with the RACH partition to initiate a RACH procedure supporting the combination of one or more RACH features associated with the RACH partition. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration for multiple sets of prioritization parameters for a random access channel (RACH) procedure. A first set of prioritization parameters of the multiple sets of prioritization parameters may be associated with a higher priority network slice than the other sets of prioritization parameters (e.g., than the remaining sets of prioritization parameters). The UE may detect a trigger to perform a RACH procedure and select the first set of prioritization parameters for the RACH procedure based on the first set of prioritization parameters being associated with the higher priority network slice. The UE may perform the RACH procedure for the network slice according to the first set of prioritization parameters.

Abstract: Disclosed is a 5' flanking sequence of the human fas gene containing a promoter region. This sequence also contains at least three transcription initiation sites, as well as consensus sequences for AP-1, GF-1, NY-Y, CP-2, EB20, and c-myb. Also disclosed are methods of altering senescence of the immune system by modifying Fas activity in cells to increase or decrease apoptosis. Fas expression and function on T cells from old (22-26-month-old) mice is also compared to young (2-month-old) mice and old CD2-fas transgenic mice. Fas expression and ligand-induced apoptosis was decreased on T cells from old mice compared to young mice. In 26-month-old CD2-fas transgenic mice, Fas and CD44 expression, Fas-induced apoptosis, T cell proliferation and cytokine production were comparable to that of the young mice.
