The present invention is a system and method capable of increasing retinal and neural glucose oxidation by enhancing pyruvate dehydrogenase activity and therefore treats retinopathy and central nervous system disorders in both diabetic and non-diabetic patients. In a first embodiment, a p-type GaN transition layer with a resistivity greater than or equal to about 7 cm is formed between a p-type conductivity layer and a metal contact. For instance, the price of energy may be monitored. Thus, the various aspects may provide a global optimization framework for dynamic compilers that is faster and more efficient than existing solutions. The test unit usable with a PCB having the electronic component includes a testing point formed on the electronic component, thereby an enhancing high integration of the board. A suitable metal material may be nickel flash treated steel or other than comparative metal material.
