... also test the hypothesis that the learned models capture general fluency properties applica- ble to human-written text. The results do not support this hypothesis: prediction ac- curacy on the new ... sentence fluency/readability. Consider the following example: • [The dog] jumped over the fence and fetched the ball. • [The big dog in the corner] fetched the ball. The long...

Increased magnification showed that the most intense staining was, as with the RAP stain, within the myotubes ... synaptogene- sis [28,30,31]. Nevertheless, the potential ligand of PTPr within developing muscle of the chick embryo appears not be HSPG-related, and only interacts wi...
