Embodiments are disclosed herein that involve C5-functionalized nucleic acids, which can be used for detecting a target in a nucleic acid. The system having a heat sink member in thermal communication with the controller, wherein the flow of the water in the water purification system cools the heat sink member and the controller unit. The thinned portions attenuate light shunted via the substrate layer and the partially transparent covering layer from the emitter to the detector, and may be configured such that less than 10% of the light detectable by the detector is shunted light. Personality type can be encoded simply as a vector of the entitys true values for attributes in the database. The performance management system generates and transmits a third instruction for an RMON database to request the RMON information.
