A transgenic mouse transformed with a DNA encoding a mutant human tau protein, wherein the mouse exhibits neurofibrillary tangles in its brain. A W-bit wide word computer capable of operating on one or more sets of k-bit operands executes Galois Field arithmetic by mapping arithmetic operations of Galois Field GF to corresponding operations in subfields lower order, which one selected on the basis of an appropriate cost function. The microcomputer then selects one of communication systems based on the profile. The transmission also includes a first support supporting the first motorgenerator such that the first motorgenerator is mounted to the first support to define a first modular unit. The method further includes setting at the conclusion of the predetermined period the predetermined financing attributes based, at least in part, on a determination of an extent of compliance of the borrower with obligations of the financial arrangement.
