In the GPRS, a method of decoding uplink status having reduced interleaving depth in a RLCMAC block is proposed; for RT-EGPRS users, all of the uplink flag bits are provided in the first burst of the four bursts; and for EGPRS users, nine bits of the uplink status flags are provided in the first burst of the RLCMAC block and the remaining bits in the next three bursts. The insulative housing defines a longitudinal main body with an inserted groove extending along a longitudinal direction, a pair of latching arms extending forwards from two opposite ends of the main body and a pair of sidewalls respectively positioned outside of the latching arms, each sidewall defines a slot therein. In particular, it relates to compounds that are selective factor XIa inhibitors.
