This article presents a survey of and an investigation into the notion of information status. Based on insights from DRT and presupposition theory a new variant of IS taxonomis is developed, considering issues such as accommodation and underspecification of text with regard to hearer knowledge.

This paper describes a fast new n{D Discrete Radon Transform (DRT) and a fast exact inversion algorithm for it, without interpolating from polar to Cartesian coordinates or using the backprojection operator. New approach is based on the fast Nussbaumer's Polynomial Transform (NPT).

This paper 1 deals with presuppositional effects by the temporal discourse markers after and before within a multi-sentence discourse. By presenting data wrt. implicitly expressed causal relations, the proposal by Lascarides and Oberlander (1993) is criticised and a formalisation of the discourse usage of the two temporal connectives is given by extending van der Sandt’s (1992) approach to pres...

This paper addresses issues related to employing logic-based semantic composition as a meaning representation for Arabic within a unification-based syntax-semantics interface. Since semantic representation has to be compositional on the level of semantic processing λ-calculus based on Discourse Representation Theory can be utilized as a helpful and practical technique for the semantic construct...

The present work continues a longer research in the field of flexible transportation services and the design of an agent system devoted to the planning, scheduling and control of trips under such a domain. In particular, this paper focuses in the design and development of the interface agents present in the system by following an agent development methodology named PASSI. The interface agent de...

BACKGROUND Deep brain stimulation of the subthalamic nuclei (STN-DBS) is an effective treatment for the most severe forms of Parkinson's disease (PD) and is intended to suppress these patients' motor symptoms. However, be it in association with Dopamine Replacement Therapy (DRT) or not, STN-DBS may in some cases induce addictive or emotional disorders. OBJECTIVE In the current study, we sugge...

Apathy and impulsivity are two major comorbid syndromes of Parkinson's disease (PD) that may represent two extremes of a behavioral spectrum modulated by dopamine-dependent processes. PD is characterized by a progressive loss of dopaminergic neurons in the substantia nigra pars compacta to which are attributed the cardinal motor symptoms of the disorder. Dopamine replacement therapy (DRT), used...

Dorsal root injury is a situation not expected to be followed by a strong regenerative growth, or growth of the injured axon into the central nervous system of the spinal cord, if the central axon of the dorsal root is injured but of strong regeneration if subjected to injury to the peripherally projecting axons. The clinical consequence of axonal injury is loss of sensation and may also lead t...

INTRODUCTION Obesity, a major public health problem, is the key modifiable component of diabetes risk. Addressing obesity and diabetes risk during primary care visits is recommended but, because of time constraints, is often difficult for health care providers to do. The purpose of this study was to determine whether technology can streamline risk assessment and leave more time to educate patie...
