objective: duplex ultrasonography is a non-invasive, non-expensive screening test for carotid disease. intima media thickness (imt) is appropriate for atherosclerosis process diagnosis. leukoaraisis (la) increase the risk of cerebrovascular accident (cva). la patients need preventive medication for cva. imt is a non-invasive diagnostic and prognostic test in la. the aim of this study was evalua...

Surrogate reasoning is reasoning whose task is partially taken over by operations on external aids, such as sentences, diagrams, physical models, mathematical models, and computers. Drawing on the basic concepts in situation theory, we present a semi-formal model of surrogate reasoning. We claim that the relative advantages and disadvantages of different forms of surrogate reasoning can be expl...

This interactive demo features MIXER, a Virtual Learning Environment (VLE) consisting of synthetic characters representing the various actors in a scenario group difference scenario. MIXER creates virtual dramas by using interactive narrative with those characters. The goal is to enable children to identify social rule differences, by interacting with one of the characters to which they become ...

We report the discovery of a new X-ray transient AGN, RX J1624.9+7554. This object appeared to be bright in the ROSAT All-Sky Survey, but had turned off in two pointed observations about one and a half years later. The optical identification spectrum shows a non-emission line spectrum of a spiral galaxy at z=0.064. We will discuss several hypotheses that can explain the peculiar behaviour of th...

Existing interlinking tools focus on finding similarity relationships between entities of distinct RDF datasets by generating owl:sameAs links. These approaches address the detection of equivalence relations between entities. However, in some contexts, more complex relations are required, and the links to be defined follow more sophisticated patterns. This paper introduces Link++, an approach t...

In this paper, we evaluate query suggestion for Boolean queries in a news monitoring system. Users of this system receive news articles that match their running query on a daily basis. Because the news for a topic continuously changes, the queries need regular updating. We first investigated the users’ working process through interviews and then evaluated multiple query suggestion methods based...

objective: to determine the effectiveness of counseling in reducing anxiety of nulliparous pregnant women. materials and methods: in this quasi-experimental study, 110 nulliparous pregnant women were selected out of all pregnant women referring to fatemieh hospital in hamadan, iran. then, the subjects were divided into two groups in experimental and control (55 women in each). the data were col...

Surrogates which allow one to predict the effect of the treatment on the outcome of interest from the effect of the treatment on the surrogate are of importance when it is difficult or expensive to measure the primary outcome. Unfortunately, the use of such surrogates can give rise to paradoxical situations in which the effect of the treatment on the surrogate is positive, the surrogate and out...
