A kit for forming a raceway assembly including a plurality of members can include a plurality of portions including channel portions and coupling portions, each of the portions extending in an axial direction and having a plurality of walls defining a generally U-shaped cross-section. According to one embodiment of the invention, a plurality of programming elements are developed and stored in a configuration repository. Thus, analysis of the expression of individual members of the library when they are expressed in cells may be carried but using instruments that can analyze the emitted light, such as a flow sorter, a spectrophotometer, a microtitre plate reader, a CCD, a fluorescence microscope, or other similar device. Hybrid maize seed, plant or plant part produced by crossing the variety PH1MBR or a locus conversion of PH1MBR with another maize variety. Each bit cell row is coupled to two or more different wordlines, where each wordline associated with a given bit cell row provides memory access to a different subset of bit cells within that bit cell row.
