... quadratic in the worst case but still linear in the best case. In Section 4, we present experi- ments indicating that the expected running time of the new system on naturally occurring data is in fact ... trees by swapping the order of words in the input. Adding the swapping operation changes the time complexity for deterministic parsing from linear to quadratic in the worst case,...

... major interaction site for the adenine moiety. In b1, an arginine residue (Ile417 in rPDE2) binds to N1 and a threonine (Ser419 in rPDE2) inter- acts with N7 and the N 6 amino group. The inter- actions ... cGMP binding [13], and, in PDE6, both of the amino acids corresponding to Phe433 ⁄ Asp434 in rPDE2A are required for cGMP binding [14]. Our initial mutations in cyaB1 GAF B also...

In giving a synonym definition, we are making use of a more general idea, namely, that of defining the intra- linguistic meaning of a word in terms of its relation...

Given the single-head constraint, parsing an in- put sentence x = (x 0 , x 1 , · ·· , x n ) is reduced to la- beling each word x j with an index i identifying its head word x i . We i...
