The thrust reverser comprises a first reverser door and a second reverser door asymmetrically pivotable between a stowed position and a deployed position, one having a pivot axis closer to the central axis than the other. The carbon black dispersion composition uses carbon black surface-modified with the benzene compound of Formula 1, or about 0. The method includes modifying at least a portion of the shape of an electric power wave, by cutting at least a portion of the wave supplied on the electrical conductor, without adversely affecting operation of the load. The coating can optionally include a biobeneficial material andor optionally with a bioactive agent. A memory includes divided source lines that permit separate data-dependent source biasing. In other embodiments, spot coverage, such as spiraling, or other modes are also used to increase effectiveness.
