A self-stabilizing dispersion composition having a copolymer having at least one polymerizable acid-containing moiety, wherein the at least one acid-containing moiety is at least partially neutralized before or during polymerization, and at least one hydrophobic moiety. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The programmed addresses are applied to a defective column decoder that determines which column select signal should be shifted downwardly and which column select signal should be shifted upwardly. The token or token set can be mapped into slots to retrieve one or more task result.
