... determin- istic parser for Chinese constituency parsing. In our approach, which is based on the shift-reduce parser for English reported in (Sagae and Lavie, 2005), the parsing task is transformed into ... de- pendency structures. For lexicalization, we used the same head-finding rules reported in (Bikel, 2004). With this additional information, reduce actions are now in the form of Redu...

... There- fore, these results clearly indicate that the electron transport system for CYP175A1 is composed of Fdx, FNR, and NADPH (Fig. 4B). All quantitative analyses were performed at 65 °C for 2 ... via OFOR and Fdx to CYP119 [13,14]. Inter- estingly, the electron transport system for CYP175A1 did not utilize OFOR, although the T. thermophilus HB27 genome contains the genes encoding OFOR...
