... of RCC1 interact with an acidic patch on the histone H2A–H2B dimer, whereas the DNA-binding loop interacts with phosphates of the nucleosomal DNA. These results are consistent with RCC1 being ... extremely rewarding, as shown by the information obtained with the tumor suppressor protein BRCA2 and its interac- tion with DNA [44,45]. As compared with protein Æ protein complexes, the...

Comparison of the amino acid sequences at the active site with other tyrosinases and catechol oxidases allows ... 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(+) wit...

... 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...

The GIZA++ and HM-BiTAM with the SRH slightly outperformed the standard GIZA++ ... alignment model. We 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...
