In previous works we considered codes defined as ideals of quotients of non commutative polynomial rings, so called Ore rings of automorphism type. In this paper we consider codes defined as modules over non commutative polynomial rings, removing therefore some of the constraints on the length of the codes defined as ideals. The notion of BCH codes can be extended to this new approach and the c...

Homogenates of the Aplysia nervous system contain protein kinase activities sensitive to cAMP, cGMP, and Ca2+/calmodulin. The cAMP- and cGMP-dependent activities are either soluble enzymes or are only loosely bound to membranes, since they can be detected only in crude but not in washed membrane fractions, and are present in 20,000 or 100,000 X g supernatants prepared from homogenates. In contr...

the article introduces cyclic dilation groups and finite affine groups for prime integers, and  as an application of this theory it presents a unified group theoretical approach for the  cyclic wavelet transform (cwt) of prime dimensional periodic signals.
