In this paper we consider combinatorial entities called balanced arrays (B-arrays) which are generalizations of orthogonal arrays (O-arrays) and balanced incomplete block designs (BIBDs). We derive some necessary conditions for the existence of such arrays by using some well-known classical inequali

β¦ Synopsis
Etzion, T., Combinatorial designs with Costas arrays properties, Discrete Mathematics 93 (1991) 143-154. Several constructions for O-l three-dimensional arrays, in which some of the two-dimenstonal subarrays have 'good' two-dimensional autocorrelation function values, i.e., the vectors connecting two l's in the matrix are all distinct as vectors, are given. Some of those constructions lead to constructions of Vatican squares in which each symbol defines a Costas array.

It is now understood that many human cancer types are the result of the accumulation of both genetic and epigenetic changes. DNA methylation is a molecular modification of DNA that is crucial for normal development. Genes that are rich in CpG dinucleotides are usually not methylated in normal tissue
