The effects of multiaccess sources and time varying multipath are considered in analyzing a system in which multiple sources communicate with a fixed base station. We discuss detection and the use of stripping in a multiaccess multipath environment. We finally derive a capacity for these systems. It turns out that CDMA type systems are inherently capable (theoretically) of higher rates than sys...

In this paper we will discuss the application of (Segmented) Discourse Representation Theory and the Generative Lexicon to the analysis of a historical French corpus of itineraries in the Pyrénées. Our research will focus in particular on how type coercion (Pustejovsky, 1995) can help us give a correct analysis of cases of so-called “fictive motion” (Talmy, 1999), which is evident is phrases like.

BACKGROUND The James Lind Alliance (JLA) created an approach to elicit the views of those under-represented in research priority exercises. Building on this, the JLA Dementia Priority Setting Partnership was set up as an independent and evidence-based project to identify and prioritise unanswered questions ('uncertainties') about prevention, diagnosis, treatment and care relating to dementia. ...

We study a class of extended quintessence cosmologies where the scalar field playing the role of the dark energy is exponentially coupled to the Ricci scalar. We find that the dynamics induced by the effective gravitational potential in the Klein-Gordon equation dominates the motion of the field in the early universe. The resulting “R−boost” trajectory is characterized by a kinetic dark energy ...
