The cellular regulation has been formulated in the more familiar framework used in control and system theory in terms of inputs as the variables which can be in uenced externally. A graph-theoretic approach has been taken to elicit the rich structure of the dynamical systems represented by metabolic pathways inside the cell. Problems of realization, analysis, and control of cell reaction networks are described.

The new NLFC processing scheme is adaptive and potentially allows for a better preservation of the spectral characteristics of the input sounds when compared to conventional NLFC processing. A repeated-measures design was utilised to compare the speech perception of the participants with two configurations of the new adaptive NLFC processing to their performance with the existing NLFC. The outcome measures included the University of Western Ontario Plurals test, the Consonant-Nucleus-Consonant word recognition test, and the Phonak Phoneme Perception test. Study participants included 14 children, aged 6-17 years, with mild-to-severe low-frequency hearing loss and severe-to-profound high-frequency hearing loss. The results indicated that the use of the new adaptive NLFC processing resulted in significantly better average word recognition and plural detection relative to th...
