This invention features a compound having the formula: 1X is O or NR1; and each of Y and Z, independently, is 2in which each of R1, R2, R3, and R4, independently, is alkyl, cyclyl, heterocyclyl, aralkyl, aryl, or heteroaryl; Ar1 is aralkyl, aryl, or heteroaryl; and Ar2 is cyclyl, heterocyclyl, aralkyl, aryl, or heteroaryl; or Ar1 and Ar2 taken together is heterocyclyl, aralkyl, or heteroaryl. The cathode active material is structurally stable, and improves the charge-discharge characteristics, cycle characteristics, high-voltage characteristics, high-rate characteristics and thermal stability of batteries. The method further includes providing an estimated phase term of the transform of the measured nonlinearity profile. In another aspect, an array may be image-processed, and then an output of the image processing may be post-processed in an automated batch process, where at least two different post-processing protocols are assigned to the output of image processing, so that processed outputs are outputted for each of the processing protocols. The image reading device includes an scanning glass, a white bar arranged opposite the scanning glass, and a drive roller provided at the white bar, the drive roller being rotated upon receiving power to allow a document to pass between the scanning glass and the white bar. The hair care compositions of the present invention, which allow for re-styling of the hair by wetting the hair with water, contain no anionic surfactants, silicones, solvents or cationic polymeric conditioning agents.
