A non-volatile memory system is organized in physical groups of physical memory locations. Embodiments of the invention can be used to provide noncontact biometrics, in small footprints. The method also includes receiving search input from the user for identifying desired content items and, in response, presenting a subset of content items to the user. The conductive particles are provided with an oil absorbing amount ranging from 10 ml100 g to 300 ml100 g. At this time, the first and second image processing conditions are associated with each other according to the reduction conditions for the generating apparatus. In particular, the inhibitors of the present invention may be useful in therapeutic applications including enhancing memory and learning functions.
