We describe a family of elements in Thompson’s group F which present a challenge to finding canonical minimal length representatives for group elements, and which show that F is not combable by geodesics. These elements have the property that there are only two possible suffixes of long lengths for geodesic paths to these elements from the identity; one is of the form g and the other of the for...

In this paper we first present some requirements for personal information agents in the Semantic Web. Then we outline our PINA project which tries to combine elements of identity management and information agents in the Semantic Web. The fundamental idea is to store references to Semantic Web annotations in identity servers as part of user profiles.

This paper argues that visual elements are becoming an increasingly important component of identity performance on social networking sites. Working from a narrative approach to identity, this paper explores how images on SNS are used both as part of an impression management strategy to present identity, and as signs that others on the site can read and interpret as they develop an understanding...

The Tc1-like transposable elements, originally described in Caenorhabditis elegans, have a much wider phylogenetic distribution than previously thought. In this paper, we demonstrate that Tc1 shares sequence identity in its open reading frame and terminal repeats with a new transposable element Barney (also known as TCb1-Transposon Caenorhabditis briggsae 1). Barney was detected and isolated by...

Correct expression of the genetic code at translation is directly correlated with tRNA identity. This survey describes the molecular signals in tRNAs that trigger specific aminoacylations. For most tRNAs, determinants are located at the two distal extremities: the anticodon loop and the amino acid accepting stem. In a few tRNAs, however, major identity signals are found in the core of the molec...

The well-known Prager–Synge identity is valid in H1(Ω) and serves as a foundation for developing equilibrated posteriori error estimators continuous elements. In this paper, we introduce new identity, that may be regarded generalization of the to piecewise functions diffusion problems. For nonconforming finite element approximation arbitrary odd order, improve current methods by proposing fully...

The present experiment investigates the input coding mechanisms of 3 common printed characters: letters, numbers, and symbols. Despite research in this area, it is yet unclear whether the identity of these 3 elements is processed through the same or different brain pathways. In addition, some computational models propose that the position-in-string coding of these elements responds to general f...
