Statistical geometry in sequence space: a method of quantitative comparative sequence analysis.

A statistical method of comparative sequence analysis that combines horizontal and vertical correlations among aligned sequences is introduced. It is based on the analysis mainly of quartet combinations of sequences considered as geometric configurations in sequence space. Numerical invariants related to relative internal segment lengths are assigned to each such configuration and statistical a...

STATISTICAL PREDICTION OF THE SEQUENCE OF LARGE EARTHQUAKES IN IRAN

The use of different probability distributions as described by the Exponential, Pareto, Lognormal, Rayleigh, and Gama probability functions applied to estimation the time of the next great earthquake (Ms≥6.0) in different seismotectonic provinces of Iran. This prediction is based on the information about past earthquake occurrences in the given region and the basic assumption that future seismi...

A new sequence space and norm of certain matrix operators on this space

In the present paper, we introduce the sequence space [{l_p}(E,Delta) = left{ x = (x_n)_{n = 1}^infty : sum_{n = 1}^infty left|  sum_{j in {E_n}} x_j - sum_{j in E_{n + 1}} x_jright| ^p < infty right},] where $E=(E_n)$ is a partition of finite subsets of the positive integers and $pge 1$. We investigate its topological properties and inclusion relations. Moreover, we consider the problem of fin...

Double Sequence Iterations for Strongly Contractive Mapping in Modular Space

In this paper, we consider double sequence iteration processes for strongly $rho$-contractive mapping in modular space. It is proved, these sequences, convergence strongly to a fixed point of the strongly $rho$-contractive mapping.

Comparative sequence analysis of tmRNA.

Minimal secondary structures of the bacterial and plastid tmRNAs were derived by comparative analyses of 50 aligned tmRNA sequences. The structures include 12 helices and four pseudoknots and are refinements of earlier versions, but include only those base pairs for which there is comparative evidence. Described are the conserved and variable features of the tmRNAs from a wide phylogenetic spec...
