The incorporation of purified neutral protease and class I & class II collagenase isolated from C. histolyticum culture supernatants into defined tissue dissociation enzyme (TDE) mixtures was in part responsible for the success of the Edmonton protocol. The enzyme composition of Liberase HI Purified Enzyme Blend (HI) was determined by using design of experiment methodology to optimize the conce...

A new representation of audio noise signals is proposed, based on symmetric -stable (S S) distributions in order to better model the outliers that exist in real signals. This representation addresses a shortcoming of the Gaussian model, namely, the fact that it is not well suited for describing signals with impulsive behavior. The -stable and Gaussian methods are used to model measured noise si...
