A mold for a tread layer having tread-forming side and sole-forming side, the sole-forming side having a plurality of mold elements extending therefrom toward the tread-forming side. Illustratively, the master is used for printing servo patterns on a magnetic recording medium. The new cultivar is a Chlorophytum laxum suitable as an indoor pot plant. Further, a wide range antenna for the wide range sector and narrow range antennas for the narrow range sectors are separately prepared for the base station. The method further includes sending a challenge to the MRAM cell array that reads logical states of select MRAM cells of the array, and obtaining a response to the challenge from the MRAM cell array that includes the logical states of the selected MRAM cells of the array.
