Evidence for the above claim comes from my recent work on understanding subdialogues in conversation [Loc93]. Following the work of Grosz and Sidner [GSg0], I view discourse behavior as an instance of the more general phenomenon of collaboration. For agents to successfully collaborate on a task, they must hold certain beliefs and intentions regarding the acts they will perform to accomplish tha...

The aim of this study was to evaluate whether the modification in the silver component is capable of providing GuttaFlow 2 with antibacterial activity against Enterococcus faecalis compared with epoxy resin-based (AH Plus) and zinc oxide and eugenol-based (Endofill) sealers. The antibacterial activity was evaluated using a reference strain of E. faecalis (ATCC 29212). Freshly mixed sealers were...

Recently, a diagnostic strategy using a clinical decision rule, D-dimer testing and spiral computed tomography (CT) was found to be effective in the evaluation of patients with clinically suspected pulmonary embolism (PE). However, the rate of venous thromboembolic complications in the three-month follow-up of patients with negative CT was still substantial and included fatal events. It was the...

In this paper, we propose a high capacity dataembedding system in DCT domain for colored images and review the existing high capacity data embedding systems both in spatial domain as well as transform domain. The embedding is done on the quantized DCT coefficients using the concept of Hadamard Matrix. The system has very high capacity as comparable to the existing techniques of DCT domain. The ...

This paper reports on an experimental study of the interpretation of pronouns in Chinese which provides additional support for the proposal in Yang et al. (1999, 2003) that the resolution of pronominal reference in Chinese is more influenced by syntactic information than often assumed in approaches to discourse anaphora in Chinese such as Li and Thompson (1979), Givon (1983), Chen (1986), Chris...

PURPOSE To determine the relationship between dynamic contour tonometry (DCT), Goldmann applanation tonometry (GAT) and pneumotonometry (PNT) in ocular hypertension patients (OHT) and their relationship to central corneal thickness (CCT) and ocular pulse amplitude (OPA). METHODS Sixty patients (101 eyes) with intraocular pressure (IOP) ≥21 mmHg using GAT and normal appearing optic nerve heads...

PURPOSE To investigate the test-retest variability of and factors associated with the corneal deformation response, and evaluate its impact on IOP measurement. METHODS Forty normal and 140 glaucoma suspect/glaucomatous eyes of 104 individuals were prospectively included for repeated measurements of corneal deformation response by an ultra-high-speed Scheimpflug camera, followed by corneal hys...
