A method is disclosed for handling packet data. This is accomplished by: 1) Analysis of 2-3 kb upstream of open reading frames to identify promoter SNPs likely to be functional. The substrate with the patterned small molecule organic semiconductor layer is prepared by exposing a region of a substrate having thereon a film of a precursor of a small organic molecule to energy from an energy source to convert the film of a precursor of a small organic molecule to a patterned small molecule organic semiconductor layer. 0 parts by weight, in terms of Co3O4, of Co added to the Ni\u2014Zn\u2014Cu-based magnetic ferrite material.
