OBJECTIVE: The present study was aimed at evaluating the BI-RADS® classification accuracy in mammography. Additionally, the frequency of different findings was described and the interobserver agreement was evaluated. MATERIALS AND METHODS: Mammographic images of 115 patients were independently and blindly reviewed by two specialists in compliance with BI-RADS recommendations, and later compared...

We have developed a technique for authoring a nonlinear plot and for managing a story according to the plot in an interactive story-based virtual reality application. The technique exploits Petri Nets that alter reactive plans controlling individual actors. Its main advantage is that it allows for iterative design and copes with large virtual worlds inhabited with tens of actors. In this paper,...

Count data arise in numerous fields of interest. Analysis of these data frequently require distributional assumptions. Although the graphical display of a fitted model is straightforward in the univariate scenario, this becomes more complex if covariate information needs to be included into the model. Stratification is one way to proceed, but has its limitations if the covariate has many levels...

The increasing complexity of interactive applications and crescent demand for educational systems aggravates the urge for a balance between interactivity and scripted content. Approaches to this problem have ranged from a focus on interactivity and emotional engagement to linear narratives, with limited interactive capacities. The introduction of non-linearity frequently imposes a heavy burden ...

Abstract Magnetic phase coexistence in the substituted perovskite compound, La 0.4 Bi 0.3 Sr MnO 3 , is attributed to spontaneous moment and a step-like metamagnetic transition observed magnetization measurements its magnetically order state. The magnetism of samples reduced nanometer sizes by “top down” approach exhibits interesting changes with respect bulk, thus giving handle influencing phy...

In this paper, we introduce and study the prime, strongly prime,semiprime and irreducible fuzzy bi-ideals of a semigroup. We characterize thosesemigroups for which each fuzzy bi-ideal is semiprime. We also characterizethose semigroups for which each fuzzy bi-ideal is strongly prime.
