The present invention provides an ink jet printable phosphor ink composition for LED packaging that enables precision control of the amount and position of phosphor layers on the LED device or the LED device packaging. This novel compound has a glycogen-synthase activation ability, but activates a receptor PPAR to a low degree and is highly safe. In one embodiment, the disclosure is directed to measuring diesel particulate accumulation in a family of diesel particulate filters. These items could be used to ensure shoppers do not overlook special offers or to reduce overstocks by promoting products with a large inventory. In match simulation processing, a simulation is performed with the abilities after the change.
