A Markovian genomic concatenation model guided by persymmetric matrices
Andrew G. Hart, M. Sobottka
The aim of this work is to provide a rigorous mathematical analysis of a stochastic concatenation model presented by Sobottka and Hart (2011) which allows approximation of the firs…
An Entropy-Based Technique for Classifying Bacterial Chromosomes According to Synonymous Codon Usage
Andrew Hart, Servet Martínez
We present a framework based on conditional entropy and the Dirichlet distribution for classifying chromosomes based on the degree to which they use synonymous codons uniformly or…
A model capturing novel strand symmetries in bacterial DNA
Marcelo Sobottka, Andrew G. Hart
Chargaff's second parity rule for short oligonucleotides states that the frequency of any short nucleotide sequence on a strand is approximately equal to the frequency of its rever…
Markovianness and Conditional Independence in Annotated Bacterial DNA
Andrew Hart, Servet Martínez
We explore the probabilistic structure of DNA in a number of bacterial genomes and conclude that a form of Markovianness is present at the boundaries between coding and non-coding…
Information recovery from observations by a random walk having jump distribution with exponential tails
Andrew Hart, Fabio Machado, Heinrich Matzinger
A {\it scenery} is a coloring of the integers. Let be a recurrent random walk on the integers. Observing the scenery along the path of this random walk,…
A Gibbs approach to Chargaff's second parity rule
Andrew Hart, Servet Martínez, Felipe Olmos
Chargaff's second parity rule (CSPR) asserts that the frequencies of short polynucleotide chains are the same as those of the complementary reversed chains. Up to now, this hypothe…
