Disclosed are phosphors and, more particularly, yellow light emitting phosphors and light emitting device packages using the same. These compounds are preferably tertiary amines comprising tetrahydroquinoline and benzimidazole. A therapeutic amount of laser energy to apply is determined from a patient’s biological factors such as body mass index. A dynamic video frame is determined for each input video frame by forming a sparse combination of a second basis functions, wherein the dynamic video frames can be combined with the respective affine transforms and the common video frame to provide reconstructed video frames. With installations having multiple expansion joints, at least one of the expansion joints can be equipped with an inverted cap to form a gutter within such expansion joint.
