Disclosed are a red light-emitting nitride material, a light-emitting part and a light-emitting device comprising the same. The delay-lock loop includes a voltage-controlled delay line generating a plurality of delayed clock signals having different phases. Because the threshold potential of a gate moves inversely to its body potential, it follows then that in general, the body of a given device must be tied to the inverse of the device’s drain voltage to achieve such a desirable threshold potential modulation effect for improved device, circuit, gate and logical family operation. Selection of an option for a materialized version results in transmission of the materialized version. Collected ground truth data can then be associated with the identified image coordinates to allow for the more precise association of geographic coordinate information to points in the digital geographic imagery.
