A method of manufacturing a complimentary metal oxide semiconductor image sensor. The present invention further relates to electrical cells comprising the inventive electrode material, to specific polymers comprising polysulfide bridges, to processes for preparation thereof and to the use of the inventive cells. The processing system also includes a data selector coupled to the ALU sub-system for use with memory contention prediction. The billing system then computes an overage charge for at least a portion of the predicted quantity of telecom service and conveys at least that overage charge to the payment platform. The first and second extracellular matrices are generally as described above for the in vitro model, except that the first extracellular matrix is part of an animal model.
