text: Many daily activities present information in the form of a stream of text,
and often people can benefit from additional information on the topic discussed.
TV broadcast news can be treated as one such stream of text; in this paper we
discuss finding news articles on the web that are relevant to news currently being
broadcast.We evaluated a variety of algorithms for this problem, looking at the
impact of inverse document frequency, stemming, compounds, history, and query
length on the relevance and coverage of news articles returned in real time during
a broadcast. We also evaluated several postprocessing techniques for improving
the precision, including reranking using additional terms, reranking by document
similarity, and filtering on document similarity. For the best algorithm, 84%-91%
of the articles found were relevant, with at least 64% of the articles being on
the exact topic of the broadcast. In addition, a relevant article was found for
at least 70% of the topics.

text: 'Among the major mathematical approaches to mirror symmetry are those of Batyrev-Borisov
and Stromdnger-Yau-Zaslow (SYZ). The first is explicit and amenable to computation
but is not clearly related to the physical motivation; the second is the opposite.
Furthermore, it is far from obvious that mirror partners in one sense will also
be mirror partners in the other. This paper concerns a class of examples that
can be shown to satisfy the requirements of SYZ, but whose Hodge numbers are also
equal. This provides significant evidence in support of SYZ. Moreover, the examples
are of great interest in their own right: they are spaces of flat SLr-connections
on a smooth curve. The mirror is the corresponding space for the Langlands dual
group PGLr. These examples therefore throw a bridge from mirror symmetry to the
duality theory of Lie groups and, more broadly, to the geometric Langlands program.'

text: The moduli space of stable bundles of rank $2$ and degree $1$ on a Riemann
surface has rational cohomology generated by the so-called universal classes.
The work of Baranovsky, King-Newstead, Siebert-Tian and Zagier provided a complete
set of relations between these classes, expressed in terms of a recursion in the
genus. This paper accomplishes the same thing for the noncompact moduli spaces
of Higgs bundles, in the sense of Hitchin and Simpson. There are many more independent
relations than for stable bundles, but in a sense the answer is simpler, since
the formulas are completely explicit, not recursive. The results of Kirwan on
equivariant cohomology for holomorphic circle actions are of key importance.

text: 'In this paper we explicitly calculate the analogue of the ''t Hooft SU (2)
Yang-Mills instantons on Gibbons-Hawking multi-centered gravitational instantons,
which come in two parallel families: the multi-Eguchi-Hanson, or Ak ALE gravitational
instantons and the multi-Taub-NUT spaces, or Ak ALF gravitational instantons.
We calculate their energy and find the reducible ones. Following Kronheimer we
also exploit the U(1) invariance of our solutions and study the corresponding
explicit singular SU (2) magnetic monopole solutions of the Bogomolny equations
on flat ℝ3.'
