Social networks--diagrams which reflect the social structure of animal groups--are increasingly viewed as useful tools in behavioural ecology and evolutionary biology. Network structure may be especially relevant to the study of cooperation, because the action of mechanisms which affect the cost:benefit ratio of cooperating (e.g. reciprocity, punishment, image scoring) is likely to be mediated ...

Bow-tie antenna is one of wideband antennas [1]. It has been reported that the bow-tie antenna has been miniaturized by adding folded elements [2]. In this paper, it is shown that bending the bow-tie antenna with folded elements is effective method for miniaturization. The bent bow-tie antenna with folded elements can be more miniaturized than conventional bow-tie antenna with folded elements, ...

An anterior cruciate ligament (ACL) tear is one of the most common injuries in athletes. The arthroscopic ACL reconstruction procedure gold standard for treatment. However, improvement injury classification and suture materials has subsequently made primary repair an alternative surgical treatment option. This Technical Note describes with synthetic augmentation several high-strength sutures fi...

Asia Pacific Journal of Health Management 2014; 9: 3 00 which has evolved over time inside a hospital among different healthcare professionals for each patient admission. We find that social network attributes of degree centrality, connectedness and tie strength impact on coordination performance for PCCN. We further note that socio-demographic characteristics of patient age, patient sex and ho...

This study examines social network influences on the individual technology acceptance. Since it is believed that individuals’ trust, opinions and behavior are influenced by their network, an analysis of that network may help to provide some explanations on technology acceptance. However, since social network characteristics are group-level characteristics and the technology acceptance model (TA...

In order to investigate the effect of middle tie beams on confined masonry walls, we conducted experiments test specimens in which variables were brick strength and presence or absence beam. this paper, report effects each parameter from results obtained experiment. First, specimen composition experimental plan will be explained. The are shown below. Finally, these results, a comparative examin...

A class of statistical models is proposed which aims to recover latent settings structures in social networks. Settings may be regarded as clusters of vertices. The measurement model builds on two assumptions. The observed network is assumed to be generated by hierarchically nested latent transitive structures, expressed by ultrametrics. It is assumed that expected tie strength decreases with u...

The emergence of User Generated Content (UGC) and social media, enables common users to have great influence on other users adoption and decision making behavior. In current research, perceived information usefulness is always taken as the only antecedent of UGC adoption, which is not enough to explain the underlying mechanism, especially in new social media context. This study proposes a new t...

Constraint Satisfaction Problems and Propositional Satisfiability, are frameworks widely used to represent and solve combinatorial problems. A concept of primary importance in both frameworks is that of constraint propagation. In this paper we study and compare the amount of propagation that can be achieved, using various methods, when translating a problem from one framework into another. Our ...

BACKGROUND Endothelial receptor tyrosine kinases include 3 members of the vascular endothelial growth factor receptor (VEGFR) family and 2 members of the angiopoietin receptor (Tie) family. In addition, the VEGF(165) isoform binds to neuropilin-1 (NP-1), a receptor for collapsins/semaphorins. The importance of these receptors for vasculogenesis and angiogenesis has been shown in gene-targeted m...
