Estimation procedures for nonstationary Markov chains appear to be relatively sparse. This work introduces empirical  Bayes estimators  for the transition probability  matrix of a finite nonstationary  Markov chain. The data are assumed to be of  a panel study type in which each data set consists of a sequence of observations on N>=2 independent and identically dis...

The Tutte polynomial of a graph G, T(G, x,y) is a polynomial in two variables defined for every undirected graph contains information about how the graph is connected. In this paper a simple formula for computing Tutte polynomial of a benzenoid chain is presented.

Receptor affinity and drug delivery to the receptor sites could be determinant factors for the increased bronchial responsiveness seen in asthma. Competitive antagonism blockade which is measured as dose ratio-l (DR-I) depends only on these two factors. Therefore, in this study we have examined histamine HI blockade by chlorpheniramine on isolated tracheal chains of asthmatic compared to co...

in this paper we classify fuzzy subgroups of a rank-3 abelian group $g = mathbb{z}_{p^n} + mathbb{z}_p + mathbb{z}_p$ for any fixed prime $p$ and any positive integer $n$, using a natural equivalence relation given in cite{mur:01}. we present and prove explicit polynomial formulae for the number of (i) subgroups, (ii) maximal chains of subgroups, (iii) distinct fuzzy subgroups, (iv) non-isomorp...

For the extraction of type IV collagen, the normal placenaes at term were placed under pepsin digestion (once). To purify the extracted collagen, Saltingout and changing the PH were performed (each step twice). All steps of the extraction and purification were controlled by the SDS-PAGE electrophoresis and finally purified collagen with molecular weight 170 and 185 KD chains were obtain...

 Using a tight-binding model and transfer-matrix technique, as well as Lanczos algorithm, we numerically investigate the nature of the electronic states and electron transmission in site, bond and mixing Fibonacci model chains. We rely on the Landauer formalism as the basis for studying the conduction properties of these systems. Calculating the Lyapunov exponent, we also study the localization...

Background: The status of measles elimination is best summarized by evaluation of the effective reproduction number R; maintaining R < 1 is necessary and sufficient to achieve elimination. In the present article, we estimated reproduction number  for the measles data reported for the Fars province of Iran in 2001–03. Methods: We estimated by using sizes and durations of chains of measles transm...

background: elastomeric chains are commonly used in orthodontics. force decay in these materials poses clinical problems. the aim of this study was to evaluate the effects of three different mouthwashes on the force decay of orthodontic chains. materials and methods: in this experimental study, elastomeric chains with two different confi gurations were divided into eight groups (two control and...

In this paper, the effects of different aluminum to silicon ratios in silicate chains of calcium silicate hydrates (C-S-H) are evaluated on the diffusion coefficient of chloride ions by molecular dynamics method. Tobermorite is a crystalline phase that is used for studying C-S-H properties in nano scale, because of its analogous chemical composition to C-S-H. Aluminum incorporation in C-S-H and...

Polyclonal antibodies against kappa light chain are used to diagnose diseases producing free light chain. The kappa and lambda light chains are products of immunoglobulin synthesis and released into the circulation in minor amounts such as serum, cerebrospinal fluid, urine and synovial fluid in normal condition. The purpose of this study was the production and purification of polyclonal immunog...
