Listening is regarded as an interactive process involving decoding of information. This study was launched to find out the impact of bottom-up (BU) and top-down (TD) techniques on Iranian lower and upper intermediate learners’ listening comprehension. We selected a total of 120 participants in six intact classes, three lower intermediate and three upper intermediate. The proficiency level of th...

We consider the topological susceptibility for an SU(N) gauge theory in the limit of a large number of colors, N → ∞. At nonzero temperature, the behavior of the topological susceptibility depends upon the order of the deconfining phase transition. The most interesting possibility is if the deconfining transition, at T = Td, is of second order. Then we argue that Witten’s relation implies that ...

Tardive dyskinesia (TD) is associated with polymorphisms of the dopamine D(3), serotonin 2A and 2C receptors (DRD3, HTR2A and HTR2C, respectively). This study investigated the possible relationship between TD and the polymorphisms Ser9Gly (DRD3), 102T>C (HTR2A), -1438G>A(HTR2A) and Cys23Ser (HTR2C) in African-Caribbean inpatients. One hundred and twenty-six patients under chronic antipsychotic ...

Arnold’s diffusion in quasi integrable hamiltonian systems H(q, p) = H0(p)+μh(q, p) occurs in exponentially large time. We study an initially hyperbolic system which admits diffusion in polynomial time. Abridged english version In spite of KAM theorem, quasi integrable hamiltonian systems need not be stable. In [1], V.I. Arnold has pointed out an unstable behavior for systems with more than thr...

PURPOSE This study investigated whether past tense use could differentiate children with language impairment (LI) from their typically developing (TD) peers when English is children's second language (L2) and whether L2 children's past tense profiles followed the predictions of Bybee's (2007) usage-based network model. METHOD A group of L2 children with LI (L2-LI) and a matched group of L2-TD...

OBJECTIVE Congenital hypothyroidism (CH) is a frequent neonatal endocrine disease with an incidence of about 1:2500 worldwide. Although thyroid dysgenesis (TD) is the most frequent cause of CH cases, its pathogenesis remains unclear. The aim of this study was to screen the hematopoietically-expressedhomeobox gene (HHEX) mutations in Chinese children with TD. METHODS Genomic deoxyribonucleic a...

To analyze the effect of age in both B and T cell compartments of the immune system, we have studied the anti-dextran (Dx) B512 humoral immune response in aged C57BL/6 mice. We have used Dx in its native form, which induces a thymus-independent (TI) response, or conjugated to chicken serum albumin (CSA), which induces a thymus-dependent (TD) response. We have also analyzed the adjuvant effect o...

At the working heart of policy iteration algorithms commonly used and studied in discounted setting reinforcement learning, evaluation step estimates value states with samples from a Markov reward process induced by following decision process. We propose simple efficient estimator called loop that exploits regenerative structure processes without explicitly estimating full model. Our method enj...
