Knowledge of incidence of morphological variations in the course and branching of the carotid arteries is important for radiological interpretation and surgical correction when they are symptomatic. Internal carotid artery (ICA) is known to show elongation in its extra cranial course. Previous studies have demonstrated the incidence and clinical symptoms of this morphological entity. However, t...

asthma is one of the most common acute and chronic conditions in children, and the pediatricians are expected to provide an important role for asthma care in this age group, however there is no published information describing the different aspects of their practices about children asthma in iran. this study was done to characterize the knowledge of the iranian pediatricians about the diagnosis...

Background: Sarcoidosis is a multisystem granulomatous disease. Co-existence with spondyloarthritis (SA) has been more described as an adverse effect of anti-TNF α therapy than an association. We report herein a case of a typical sarcoidosis confirmed by histological proofs and an advanced SA with a bamboo column. Case Presentation: A 48-years-old woman presented with inflammatory back p...

Background The aim of this survey was to explore the baseline knowledge of the Iranian community about Chronic Kidney Disease (CKD) definition and its two main risk factors, i.e. diabetes and hypertension. This study also introduced a model of public education program with the purpose of reducing the incidence of CKD in high-risk groups and thereby decreasing the economic burden of CKD in Iran....

Generation of Referring Expressions is concerned with distinguishing descriptions for target referents in a knowledge base. Plural reference introduces novel problems, one of which is the collective/distributive distinction. This paper presents an empirical study of the production of collective spatial references, and an algorithm that determines content for such expressions from spatial data.

We observe that in certain two-player repeated games of incomplete information, where information may be incomplete on both sides, it is possible for an informed player to signal his status as an informed player to the other without revealing any information about the choice of chance. The key to obtaining such a class of games is to relax the assumption that the players’ moves are observable. ...

Information Extract ion (IE) systems today are commonly based on pat tern matching. The pat terns are regular expressions stored in a customizable knowledge base. Adapting an IE system to a new subject domain entails the construction of a new pat tern base a t ime-consuming and expensive task. We describe a s trategy for building pat terns from examples. To adapt the IE system to a new domain q...

The CONCERTO project, primarily concerned with the annotation of texts for their conceptual content, combines automatic linguistic analysis with manual annotation to ensure the accuracy of fact extraction, and to encode content in a rich knowledge representation framework. The system provides annotation tools, automatic multi-level linguistic analysis modules, a partial parsing formalism with a...

Garing et al [3] is the first paper in which Bayesian Nash equilibrium is treated. They analysis Bayesian extension of routing game specified by the type-space model of Harsanyi [4] as information structure, and they collected several results: (1) the existence and computability of pure Nash equilibrium, (2) the property of the set of fully mixes Bayesian Nash equilibria and (3) the upper bound...
