Effect of environmental stress on regulation of gene expression in the yeast
Gross, Eitan - In: Physica A: Statistical Mechanics and its Applications 430 (2015) C, pp. 224-235
Several mathematical models have been proposed to predict the activation state of a transcription factor (TF) from the expression levels of its target genes. This inference problem is complicated however due to the fact that different genes may be regulated by different activation schemes...

Statistical analysis of gene and intergenic DNA sequences
Kugiumtzis, D.; Provata, A. - In: Physica A: Statistical Mechanics and its Applications 342 (2004) 3, pp. 623-638
Much of the on-going statistical analysis of DNA sequences is focused on the estimation of characteristics of coding and non-coding regions that would possibly allow discrimination of these regions. In the current approach, we concentrate specifically on genes and intergenic regions. To estimate...

Long range correlation and possible electron conduction through DNA sequences
Wang, Sheng-Cheng; Li, Ping-Cheng; Tseng, Hsen-Che - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 21, pp. 5159-5168
Long range correlation analysis and charge conductivity investigation are applied to sequences in 16 chromosomes in the Saccharomyces cerevisiae genome. DNA sequence data are analyzed via Hurst’s analysis and Detrended Fluctuation Analysis (DFA) analysis. Super diffusive nature of mapping...

Interpreting correlations in biosequences
Herzel, H; Trifonov, E.N; Weiss, O; Große, I - In: Physica A: Statistical Mechanics and its Applications 249 (1998) 1, pp. 449-459
Understanding the complex organization of genomes as well as predicting the location of genes and the possible structure of the gene products are some of the most important problems in current molecular biology. Many statistical techniques are used to address these issues. A central role among...

Approximating long-memory DNA sequences by short-memory process
Gao, Jie; Xu, Zhen-yuan; Zhang, Li-ting - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 17, pp. 3475-3485
This paper analyzes the approximation of a general long-memory ARFIMA (p,d,q) process by a short-memory ARMA(1, 1) process. To validate this approximation, a mean square error forecast criterion is considered, and the calculation of the mean square error between the observation Xt+l of an ARFIMA...

A novel representation of DNA sequence based on CMI coding
Hou, Wenbing; Pan, Qiuhui; He, Mingfeng - In: Physica A: Statistical Mechanics and its Applications 409 (2014) C, pp. 87-96
Graphical representation of DNA sequences provides a simple and intuitive way of analyzing and sorting various gene sequences. It is attractive to researchers to propose much more appropriate methods. In this study, a new graphical representation is presented. The method adopts the CMI coding to...

The Pareto law of incomes—an explanation and an extension
Reed, William J. - In: Physica A: Statistical Mechanics and its Applications 319 (2003) C, pp. 469-486
A stochastic model for the generation of observed income distributions is used to provide an explanation for the Pareto law of incomes. Analysis of the model also yields a prediction of Paretian (power law) behaviour in the lower tail of the distribution and this is shown to occur in a number of...

Generalized entropies and quantum entanglement
Canosa, N.; Rossignoli, R. - In: Physica A: Statistical Mechanics and its Applications 329 (2003) 3, pp. 371-376
We discuss the fundamental properties of general entropic forms based on arbitrary concave functions and their application to current problems of quantum information theory. It is first shown that the extended formalism allows to construct, for a two-qubit system, least biased density operators...
