Introduction: Breast neoplasia is the most common cancer among women in both developed and developing countries. Over 1.15 million women in the world detecting with breast neoplasia each year and the mortality rate is 502,000 cases from this cancer. The purpose of this study was to describe how Iranian women perform breast self-examination. Materials and methods: In this cross-sectional study...

In this paper, we propose the first network performance measure that can be used to assess the efficiency of a network in the case of either fixed or elastic demands. Such a measure is needed for many different applications since only when the performance of a network can be quantifiably measured can the network be appropriately managed. Moreover, as we demonstrate, the proposed performance mea...

A Self-Organizing Network (SON) performs automated network management through the coordinated execution of autonomous functions, each aiming to achieve a specific objective like the optimization of a network Key Performance Indicator (KPI) value. However, there are situations in which a SON function cannot achieve its objective which can lead to disturbed SON operation and inferior performance....

Goal setting difficulty has been shown to contribute to athletic performance (Burton et al., 2000). However, the potential mediating mechanism of goal difficulty on performance is unclear. Therefore, the purpose of this study was to verify the effect of goal setting difficulty on serving success in table tennis, and determine if self-regulation is the mediating variable. The current study used ...

Trait anxiety is a personality characteristic that describes the tendency to feel anxious across a variety of situations, while state anxiety refers to the anxiety experienced in a specific situation (Cox, 2007). Previous research has suggested that high trait anxious individuals experience more situation-specific state anxiety (Horikawa & Yagi, 2012). Additionally, prior research has indicated...

Transport level multicast protocols providing reliability and scalability properties are certainly essential building blocks for several distributed group applications. We consider the effect of reliable multicast transport mechanisms on traffic characteristics and hence network performance. Although self-similarity property of unicast traffic, in particular TCP, has been analyzed extensively, ...
