Cluster Analysis and Phylogenetic Relationship in Biomarker Identification of Microarray Data of Type 2 Diabetes and Nephropathy in Asian Indians.

Processing of plural works can be made simultaneously by using divided laser beams which is issued from one large Co2 laser beam source, the dividing being made by one or more rotary chopper mirror(s) comprising reflecting parts and light passing parts, and its ration and pulsive start and stop of laser oscillation are controlled in interrelated manner and by controlling the duty time of the laser oscillation in PWM manner. The distribution of powers of the laser beams divided by the rotary chopper mirrors is desirably selectable, thereby enabling simultaneous processing of plural works under the different processing conditions.
