• Topology of G/T : Flag manifolds G/T have cohomology only in even degrees, with Euler characteristic the degree of the Weyl group. The Euler characteristic can be calculated by a Lefschetz fixed point argument (see Adams [1], pgs. 90-92 for this). Identifying the flag manifold with a co-adjoint orbit, there is a Morse theory calulation of the cohomology that goes back to Bott, for an outline ...

Many applications in machine learning, natural language processing, and information retrieval require methods for representing and computing with text documents. In this review, we discuss techniques that use latent, topical information in text documents for solving problems in these fields. We consider approaches to problems such as document retrieval, topic tracking, novel event detection, do...
متن کاملPosting Topics \ne ≠ Reading Topics: On Discovering Posting and Reading Topics in Social Media
Social media users make decisions about what content to post and read. As posted content is often visible to others, users are likely to impose self-censorship when deciding what content to post. On the other hand, such a concern may not apply to reading social media content. As a result, the topics of content that a user posted and read can be different and this has major implications to the a...
متن کاملAccommodating Topics
This paper concerns the relevance of notions of sentence topic and discourse topic to the analysis of sentences containing presuppositions. Firstly I consider sentences where quantificational determiners quantify-in to presuppositions. By considering texts containing such sentences, I show that intermediate accommodation cannot be triggered by presuppositions, contrary to the predictions of van...

Background: Childhood trauma is a major risk factor for the development of affective disorders later in life. We sought to determine whether this risk is linked to neurostructural changes in limbic brain regions after childhood trauma. Methods: We recruited 49 medically healthy adult women (28.297.1 years of age) from the Atlanta area to include women with/without childhood trauma and with/with...
