A plurality of three-terminal variable resistance switching elements each having a source electrode, a drain electrode, and a gate electrode are connected to each other in series. The present also discloses a method for using Spectral Fluorescence Signature technology for fast and accurate drug detection, quantification and data storage. 5 wt %\u02dc40 wt % styrene with polymerization inhibitors removed by evaporation, 2. If the determined state of the transmission is a non-drive range, the transmission state determination unit drives the pinion gear thrust unit at timing determined by a second pinion gear thrust timing determination unit.
