In this paper, a new model, addressing the Associative Reinforcement Learning (ARL) problem, based on learning automata and self organizing map is proposed. The model consists of two layers. The First layer comprised of a SOM which is utilized to quantize the state (context) space and the second layer contains of a team of learning automata which is used to select an optimal action in each stat...

Background: Nowadays, due to the emergence of drug resistance to antibiotics, a good alternative to drugs should be found. Bacteriophages are viruses that play a very important role in the destruction of bacteria. Because of their specific properties, bacteriophages can be considered as suitable substitutes for antibiotics in the treatment of infectious diseases. The aim of this study was to is...

Background and purpose: Activation-induced cytidine deaminase (AID) is a B-cell specific enzyme responsible for somatic hypermutation (SHM) and class switch recombination (CSR) of antibody genes within the B-cell follicle of peripheral lymphoid organs. Ectopic overexpression of the enzyme leads to mutations in non-B cells and Escherichia coli (E.coli) genes. However, induction of mutations in E...
