in this study, a simple and reliable square wave voltammetric (swv) method was developed and validated for determination of diclofenac in pharmaceutical preparations and human serum. the proposed method was based on electrooxidation of diclofenac at platinum electrode in 0.1 m tbaclo4/acetonitrile solution. the well-defined two oxidation peaks were observed at 0.87 and 1.27 v, respectively. cal...

The probability of a rare event is usually estimated directly as the number of times the event occurs divided by the total sample size. Unfortunately, the precision of this estimate is low. For typical sample sizes of N , 100 in ecological studies, the coefficient of variation (CV) of this estimate of the probability of a rare event can exceed 300%. Sample sizes on the order of 103–104 observat...

BACKGROUND Mobility impairment is common in people with multiple sclerosis (PwMS) and there is a need to assess mobility in remote settings. Here, we apply a novel wireless, skin-mounted, and conformal inertial sensor (BioStampRC, MC10 Inc.) to examine gait characteristics of PwMS under controlled conditions. We determine the accuracy and precision of BioStampRC in measuring gait kinematics by ...
