AIM The aim of this study was to compare canal transportation and centering ability of Twisted files (TF) and ProTaper (PT) files with conventional stainless steel (SS) K files. MATERIALS AND METHODS Thirty mandibular premolar teeth with root curvature of 25 to 35° were selected. The samples were randomly divided into three groups of 10 each according to the type of files used for instrumenta...

Centering was formulated as a model of the relationship between attentional state, the form of referring expressions, and the coherence of an utterance within a discourse segment (Grosz, Joshi and Weinstein, 1986; Grosz, Joshi and Weinstein, 1995). In this chapter, I argue that the restriction of centering to operating within a discourse segment should be abandoned in order to integrate centeri...

Considering empirical evidence from a free-word-order language (German) we propose a revision of the principles guiding the ordering of discourse entities in the forward-looking center list within the centering model. We claim that grammatical role criteria should be replaced by criteria that reflect the functional information structure of the utterances. These new criteria are based on the dis...

As the amplification of seismic force demands due to higher-mode effects on tall buildings is increasingly recognized as a design challenge, number high-performance systems have been proposed limit such through combined base shear-limiting and moment-limiting dual mechanisms. To better understand influence these overall behavior buildings, this paper presents study response Multi-Degree-of-Free...

This study presents a novel self-centering (SC) base isolation system enabled by traditional lead rubber bearing (LRB) incorporating superelastic shape memory alloy (SMA) U-shaped dampers (hereinafter referred to as SMA-LRB). is particularly suitable for some important structures (e.g., hospital buildings) that require high seismic performance and rapid recovery of normal serviceability after s...

We report the results of an experiment probing the relative influence of centering and anchoring biases in reconstructive memory for line lengths. On each of 90 trials participants (N=120) viewed a target line, which they reproduced after a delay by adjusting a response line. We manipulated the starting size of this response line in three conditions: one provided an anchoring bias opposite the ...
