Epidemiological evidence suggests that infection is involved in the etiology of common acute lymphoblastic leukemia, either by stimulating an inappropriate immune response or in the form of a classical transforming agent. In an attempt to elucidate the role that infection is playing in this disease, we used representational difference analysis (RDA) to examine tumor samples for the presence of ...

We evaluated the predictions of Grosz and Sidner’s theory of anaphoric accessibility using a corpus of tutorial dialogues whose discourse structure was annotated according to Relational Discourse (RDA) Analysis. We found support for Moser and Moore’s proposal that only segments with an intentional core should be viewed as introducing new focus spaces; we also found that both embedded cores and ...

Differential microphone array is known to have low sensitivity to distant sound sources. Such characteristics may be advantageous in voice activity detection where it can be assumed that the target speaker is close and background noise sources are distant. In this paper we develop a simple modification to the EVRC rate determination algorithm (EVRC RDA) to exploit the noise-canceling property o...
