verb system and its construction are two of the most important issues in the grammar of middle iranian languages. comparing the construction of verbs in middle iranian languages and dialects reveals their relation with old iranian languages. the aim of this research therefore is first to review the construction of verbs in bactrian as one of the eastern middle iranian languages and second to fi...

Due to its critical role in NK cell differentiation and CD8(+) T cell homeostasis, the importance of IL-15 is more firmly established for cytolytic effectors of the immune system than for CD4(+) T cells. The increased levels of IL-15 found in several CD4(+) T cell-driven (auto-) immune diseases prompted us to examine how IL-15 influences murine CD4(+) T cell responses to low dose TCR-stimulatio...

the present article tries to prove that there is a reverse relation between the role of state in political society and its liability. in other words, the greater state’s interference with the political society, the less will be its responsibility and hence its liability. on contrary, making limitation to the state’s role in political society will increase its responsibility and thus its liabili...

Analogy is often viewed as a partial similarity match between domains. But not all partial similarities qualify as analogy: There must be some selection of which commonalities count. Three experiments tested a particular selection constraint in analogical mapping, namely, systemoticity. That is, we tested whether a given predicate is more likely to figure in the interpretation of and prediction...

We study the entanglement of a two-qubit one dimensional XYZ Heisenberg chain in thermal equilibrium at temperature T. We obtain an analytical expression for the concurrence of this system in terms of the parameters of the Hamiltonian and T. We show that depending on the relation among the coupling constants it is possible to increase the amount of entanglement of the system increasing its anis...

A new set of special functions is described which has a wide range of applications, from number theory to integrability of non-linear dynamical systems. We study multiple orthogonal polynomials with respect to p > 1 weights satisfying Pearson’s equation. In particular, we give a classification of multiple orthogonal polynomials with respect to classical weights which is based on properties of t...

In this paper, we study the forced oscillation of the higher-order nonlinear difference equation of the form m x(n) – p(n)x(n – τ) + q 1 (n) α (n – σ 1) + q 2 (n) β (n – σ 2) = f (n), where m ≥ 1, τ , σ 1 and σ 2 are integers, 0 < α < 1 < β are constants, * (u) = |u| *–1 u, p(n), q 1 (n), q 2 (n) and f (n) are real sequences with p(n) > 0. By taking all possible values of τ , σ 1 and σ 2 into c...
