A circuit and a method of operation to reduce dynamic and static power dissipation in the circuit are disclosed. The directory manager file includes an encryption key for a segment that is used when reconstructing a target file. The movement controller of the holder comprises a three-dimensional control curve and a guide element, which engages at different depths in the control curve as a function of its relative position. In some other embodiments, such plasticizer compositions are used to lower the glass transition temperature of a polymer resin. In certain embodiments, the coloring flakes have a size distribution characterized in that at least 90 weight percent of the coloring flakes are retained by a 20 mesh sieve. Laser light emitted from the semiconductor laser enters the optical waveguide part.
