... for inference. In another 28%, references could optionally support the inference of the hypothesis. In the remaining 28%, refer- ences did not contribute towards inference. The total number of ... enough; (3) the limitation to nominal coreference; and (4) overly simple integration of reference information into the inference engines. The goal of this paper is to ass...

Using hourly cost, Figure 2 shows the cost reduction curves of several ... expand the goal of AL to produce the annotated set ˆ A such that the benefit gained is maximized and cost is minimized. In the case of POS tagging, tag accuracy is...

Another notable feature of the single-site IC mutants (including the glutamine substitutions) [39] is the fact that, in the absence of Vi (± drugs) labeling of the enzymes with the ... in the glutamine (length of the side chain maintained) and asparagine (shorter side chain) mutants, then trapping in the absence of Vi now occurs [39] (Fig. 3);...

For instance, instead of representing the...

... N-terminus modulates their activity [36,37]. The current hypothesis involves domain–domain interac- tions between the N-terminus and other domains of the ATPase. Indeed, in vitro studies of the ... N-terminus of the ATPase. To further study the role of the Ccc2 N-terminus in the overall function of the ATPase in vivo, we engi- neered DMBDCcc2 (Fig. 1E), a p...
