AIMS The purpose of this study was to compare the canal centering abilities of rotary nickel-titanium (NiTi) files (ProFile 0.04 and 0.06 and Lightspeed LSX) and NiTi hand K-files in 10° to 25° curved canals. This was compared with the canal centering ability of stainless steel hand K-files using Kuttler's endodontic cube. SETTINGS AND DESIGN The teeth with a 10° to 25° of clinical mesiodista...

background: the aim of this study was to evaluate apical transportation and centering ability of single-fi le instruments, waveone primary, with full rotation versus reciprocation movement using cone-beam computed tomography (cbct) analysis in curved mesiobuccal (mb) root canal of human mandibular molars. materials and methods: thirty mb canals of mandibular molars were randomly divided into tw...

‎A full Nesterov-Todd (NT) step infeasible interior-point algorithm‎ ‎is proposed for solving monotone linear complementarity problems‎ ‎over symmetric cones by using Euclidean Jordan algebra‎. ‎Two types of‎ ‎full NT-steps are used‎, ‎feasibility steps and centering steps‎. ‎The‎ ‎algorithm starts from strictly feasible iterates of a perturbed‎ ‎problem‎, ‎and, using the central path and feasi...

We specify an algorithm that builds up a hierarchy of referential discourse segments from local centering data. The spatial extension and nesting of these discourse segments constrain the reachability of potential antecedents of an anaphoric expression beyond the local level of adjacent center pairs. Thus, the centering model is scaled up to the level of the global referential structure of disc...

The purpose of the study reported in this paper is to investigate how local focusing structure, analysed in terms of Centering Theory (Grosz, Joshi & Weinstein, 1995), and global d iscourse structure, analysed in terms of discourse segments and discourse segment purposes (Grosz & Sidner, 1986), interact. Swedish dialogue was analysed according to Centering Theory and Grosz and Sidners (1986) di...

A case study on automotive lane centering control is examined in Hybrid Event-B (an extension of Event-B that includes provision for continuously varying behaviour as well as the usual discrete changes of state). This allows aspects beyond the reach of a discrete Event-B treatment to be more deeply investigated. Lane centering offers particular challenges concerning how the monitoring of contin...

We consider the effect on estimation of simultaneous variable centering and interaction effects in linear regression. We technically define, review, and amplify many of the statistical issues for interaction models with centering in order to create a useful and compact reference for teachers, students, and applied researchers. In addition, we investigate a sequence of models that have an intera...

This paper presents our preliminary work in developing a Natural Language Processing (NLP)-enhanced Computer-Assisted Language Learning (CALL) program for Japanese learners that supports reading comprehension and writing revision process with focus on zero anaphora. We first discuss the pedagogical status of zero anaphora in a Japanese as a Second Language (JSL) learning environment, and argue ...

Many efforts in corpora annotation start with segmenting discourse into units of analysis. In this paper, we present a method for deciding on segmentation units within Centering Theory (Grosz, Joshi, & Weinstein, 1995). We survey the different existing methods to break down discourse into utterances and discuss the results of a comparison study among them. The contribution of our study is that ...

Computational research on reference resolution has mostly focused on pronouns and, to a lesser extent, on definite descriptions. We present a computational treatment of other-anaphora, i.e., noun phrases modified by “other” and “another”. The approach presented here is a lexical method LEX that finds antecedents on the basis of information in WordNet. LEX is compared with the state-of-the-art p...
