Entity linking is the task of disambiguating entities in unstructured text by linking them to an entity in a catalog. Several collective entity linking approaches exist that attempt to collectively disambiguate all mentions in the text by leveraging both local mention-entity context and global entity-entity relatedness. However, the complexity of these models makes it unfeasible to employ exact...

Using the BSBM varying-alpha theory, with dark matter dominated by magnetic energy, and the spherical collapse model for cosmological structure formation, we have studied the effects of the dark-energy equation of state and the coupling of alpha to the matter fields on the space and time evolution of alpha. We have compared its evolution inside virialised overdensities with that in the cosmolog...

We introduce a new measure for the capital market efficiency. The measure takes into consideration the correlation structure of the returns (long-term and short-term memory) and local herding behavior (fractal dimension). The efficiency measure is taken as a distance from an ideal efficient market situation. Methodology is applied to a portfolio of 41 stock indices. We find that the Japanese NI...

Determining the structural properties of mRNA is key to understanding vital post-transcriptional processes. As experimental data on mRNA structure are scarce, accurate structure prediction is required to characterize RNA regulatory mechanisms. Although various structure prediction approaches are available, it is often unclear which to choose and how to set their parameters. Furthermore, no stan...

In this study the local and global prosodic exponents of information structure are examined in the production of six Bulgarian question-answer elicited sentences under different focus conditions (broad focus and non-contrastive and contrastive narrow focus). Local cues are the phonetic properties of the nuclear accented syllables, while global cues reflect broader phonetic patterns in the inter...

We re-examine some topics in representation theory of Lie algebras and Springer theory in a more general context, viewing the universal enveloping algebra as an example of the section ring of a quantization of a conical symplectic resolution. While some modification from this classical context is necessary, many familiar features survive. These include a version of the Beilinson-Bernstein local...
