... Methods quality of the proposed methods (simple feedback cleaning and cross-cleaning) are considerably im- proved over those of the previous methods. Focusing on the subjective quality of the proposed methods, ... This similarity is measured by N-gram precision scores. Several kinds of N-grams can be used in BLEU. We use from 1-gram to 4-gram in this paper, where a 1-gram precision score...

For this pur- pose, differentially tagged mini-receptors were co-immunoprecipitated using a FLAG-based antibody from lysates ... diges- tion using subtilisin. They determined that repeats 1–3 and 7–10 can independently bind Man-6-P-containing ligands. Dahms et al. [19] further defined the location of Man-6-P bin...

No ... binding to the protein, saturation experiments were undertaken. Namely, 10 lm of stefin B was exposed to 10, 20, 50 and 100 lm of Cu(II) as Cu 2+ -Gly chelate. The protein was dia- lysed and the .....
