Background: To explore a possible rela!onship among blood groups and the prognosis of breast cancer, this case- control study was carried out in Arak city, Arak province, Iran. Materials and Methods: One hundred and thirty four pa!ents with breast cancer were inves!gated. ABO blood groups were obtained from medical records. Mul!variate analyses were performed, including size of tumor, axilla...

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.

Large water distribution systems can be highly vulnerable to penetration of contaminant factors caused by different means including deliberate contamination injections. As contaminants quickly spread into a water distribution network, rapid characterization of the pollution source has a high measure of importance for early warning assessment and disaster management. In this paper, a methodology...

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...
