A central claim of centering theory (Grosz, Joshi, and Weinstein, 1995, henceforth GJW) is that certain entities mentioned in an utterance are more central than others, and that this property imposes constraints on a speaker’s use of different types of expressions to refer to them. To articulate some of these constraints, they define several fundamental centering concepts and propose rules base...

Inequalities for martingales with bounded differences have recently proved to be very useful in combinatorics and in the mathematics of operational research and computer science. We see here that these inequalities extend in a natural way to ’centering sequences’ with bounded differences, and thus include for example better inequalities for sequences related to sampling without replacement. 1 C...

Since pronouns can be dropped in Thai, a natural language processing system for Thai must be able to resolve referents of the missing pronouns. One of several approaches that have been used for reference resolution is Centering Theory. Centering Theory is a focusing process in which salience of discourse entities is being kept track of. Referents of pronouns or zero pronouns are usually entitie...

Base-level fall in river beds occurs due to varying natural or unnatural causes. Base-level fall causes the change in the behavior of flow at the location of drop in base-level. In such situations, most of scour occur at the foot of the slope, and slope wall retreats in the upstream direction. This phenomenon widens the wall of the river bank, thus leading to its destruction. The amount of bed ...

Identification of the nonlinear hysteretic behavior of a reinforced concrete (RC) bridge pier subjected to earthquake loads is carried out based on acceleration measurements of the earthquake motion and bridge responses. The modified Takeda model is employed to represent the hysteretic behavior of the RC pier with a small number of parameters, in which the nonlinear behavior is described by var...

Science Writer Jennifer F. Wilson The content of In the Clinic is drawn from the clinical information and education resources of the American College of Physicians (ACP), including PIER (Physicians’ Information and Education Resource) and MKSAP (Medical Knowledge and Self-Assessment Program). Annals of Internal Medicine editors develop In the Clinic from these primary sources in collaboration w...

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...

Based on the high-pile and high-pier bridge of Qianhuang Expressway, eigenvalue buckling analysis is carried out by establishing three-dimensional finite element models three different types types, corresponding structural nonlinear loads under initial pier deviations are calculated. The calculation results show that less than elastic loads. stability column continuous better simple supported b...
