A receiver includes an input, a correlator, a phase-assisted demodulator, and an output. Doughnut stencil shapes have four different patterns of struts, so that an area that is blocked by a strut in one shape is exposed in three other shapes. The output port is placed in a power-gated state if there is no activity in the output port for a current cycle and no messages are to be received by the output port during a subsequent cycle. The reservoir is formed into a journal bearing surface of the head section body and may be sealed by placing a seal around its periphery that extends between the journal bearing surface and journal sleeve. The invention also relates to methods for producing other soybean cultivars, lines, or plant parts derived from soybean cultivar UA Kirksey, and to the soybean plants, varieties, and their parts derived from use of those methods.
