220 RESERVE ALBUMIN CAPACITY FOR BILIRUBIN MEASURED BY SEPHADEX ADSORPTION (SA) AND BY ABSORBANCE DEVIATION (AD) AT SATURATION OF PRIMARY ALBUMIN-BINDING SITES [PDF]

Pediatric Research, 1981
The Reserve Bilirubin Binding Capacity (RBBC) of albumin is an indicator of the chances for brain damage due to kernicterus in the neonate. This study compares the RBBC of the neonatal serum by SA (Clin. Chem. 18(1):43, 1972) to that of AD (described elsewhere in this Program Issue, APS-SPR).

80-Gb/s OTDM system analysis of a vertical microcavity-based saturable absorber for the enhancement of pulse pedestal suppression [PDF]

, 2007
In future high-speed optical time-division-multiplexed (OTDM) systems, an important factor that needs to be considered for optical pulse generation schemes is the impact of pulse pedestals on the overall system performance.
