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, ...

Understanding the relationships between people in a social network and measuring their strength over time are interesting problems with distinct applications. Here, we propose a new algorithm (STACY) to automatically classify tie strength in eight different classes by considering the temporal aspect. Our results show: such classes represent different behaviors, and STACY identifies strong relat...

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...

Angiogenesis is coordinated with follicular cell growth in goitrogenesis. The angiopoietins, Ang-1 and Ang-2, are angiogenic growth factors acting through Tie-2, a tyrosine kinase receptor. We have examined the expression and regulation of the angiopoietins and Tie-2 in human and rat thyroids. In human goiters there was increased Tie-2 immunostaining, compared with that in normal thyroids, on b...

The odds for success of a future CAI system (as well as the present CAI movement) are completely dependent on the quality of an underlying theory of innovation and the effectiveness of its tools, processes and models. This paper establishes a set of requirements for such a theory, evaluates existing approaches, methodologies and theories (including TRIZ), and presents an overview of the General...

Social capital and social support are two key constructs in the study of social networks and health. Despite their importance, little research has sought to examine the characteristics of those social ties by which individuals access social capital and support resources. Network diversity - a key structural feature in accessing social capital - refers to a person's broad but generally weak and ...

The specific and high affinity binding properties of intracellular antibodies (intrabodies), combined with their ability to be stably expressed in defined organelles, provides powerful tools with a wide range of applications in the field of functional genomics and gene therapy. Intrabodies have been used to specifically target intracellular proteins, manipulate biological processes, and contrib...
