Methods of manufacturing MTJ memory cells and structures thereof. An indicator member when independently inserted into the slot of the teeth indexing member assists in designing and making osteotomies relative to the reference planes. In another embodiment, wherein the providing of the participants in the commodity-based supply chain further includes providing a plurality of auditors to audit one or more process points in the supply chain. The invention may use a novel approximation for calculating the total scaling values, which obtains a first term based on a corresponding distortion threshold, and obtains a second term based on a sum of the transform coefficients.
