... R3. The PCR product with a size of  1.6 kb was digested with BamHI to obtain a fragment between the two copper-binding site coding regions and ligated to pBlueScript pKSII(+) with T4 DNA ligase ... R3-1501 – than R3- 0337 – . This pattern agrees with the presence of two different enzymes with overlapping activities. Purification of two enzymes with different affinities for monophen...

... a pattern with which to expand it and then filling out that pattern with words drawn from a unigram distribution. This kind of coupled generative process can be naturally formalized with tree ... gen- erate MR and NL associated with MR rules m -v (top). Transducer rule 2 selects MR rule r from the MR gram- mar. Rule 3 simultaneously writes the MR associated with rule m and chooses an...

... formulate a syn- onym pair generative model with a topic variable and use this model as a regularization term with a bilingual word alignment model. The topic vari- able in our synonym model is ... (Zhao and Xing, 2008). HM-BiTAM is a bilingual generative model with topic z, alignment a and topic weight vec- tor θ as latent variables.
