The purpose of the paper is to construct a polyhedral Markov field in R in analogy with the planar construction of the original Arak (1982) polygonal Markov field. We provide a dynamic construction of the process in terms of evolution of two-dimensional multi-edge systems tracing polyhedral boundaries of the field in three-dimensional timespace. We also give a general algorithm for simulating G...

IgA ELISA testing for the initial treatment of .pylori infection, without alarming signs such as weight loss, blood-positive stool, palpable mass, etc. can be used. Approach has been designed based on the UBT test. Though accurate UBT testing for treatment and follow-up is better, but due to financial constraints, we would prefer to use this method.

A reversible, ergodic, Markov process taking values in the space of polygonally segmented images is constructed. The stationary distribution of this process can be made to correspond to a Gibbs-type distribution for polygonal random fields introduced by Arak and Surgailis and a few variants thereof, such as those arising in Bayesian analysis of such random fields. Extensions to generalized poly...

BACKGROUND & PURPOSE Humans act as an intermediate host for Toxocara canis and Toxocara cati. Toxocara may be an important risk factor for asthma in humans. The aim of the present study was to evaluate immunoglobulin G (IgG) anti-Toxocara canis antibody, using enzyme-linked immunosorbent assay (ELISA) in asthmatic patients (aged 5-15 years), referring to a clinic of pulmonary diseases in Arak, ...

BACKGROUND The objective of this study was to investigate HLA-DRB1*and DQB1* allelic polymorphisms in Iranian patients with hydatidose. This is the first survey dealing with the correlation between HLA-DRB1* and DQB1* alleles and cystic echinococcosis in Iranian patients. METHODS The study was carried out on 56 patients with confirmed cystic echinococcosis and 30 apparently healthy individual...

BACKGROUND This study aimed to determine the effects of the interventions of Isfahan Healthy Heart Program (IHHP) on the type of oil consumed at the population level. It also tried to assess how this strategy has been effective as a health policy. METHODS The IHHP, a six-year community intervention program (2001-07), aimed at health promotion through the modification of cardiovascular disease...

The purpose of this paper is to construct perfect samplers for length-interacting Arak–Clifford–Surgailis polygonal Markov fields in the plane with nodes of order 2 (V-shaped nodes). This is achieved by providing for the polygonal fields a hard core marked point process representation with individual points carrying polygonal loops as their marks, so that the coupling from the past and clan of ...
