These compositions are new synthetic peptides and antibodies which are potent chemotactic agents for human neutrophils, and methods for their use. The plurality of DPDT switches is coupled to the plurality of loops. The code cache includes a system for automatically keeping the code cache at an appropriate size for the current working set of an application running. The at least one tunable resistance switch is programmable to dynamically switch the at least one inductor in or out of the clock distribution to effect at least one resonant mode of operation or a non-resonant mode of operation based on a frequency of the clock signal.
