... respect. The monotonicity constraints, on the other hand, might constitute a dilution of the Shake-and-Bake ideal of independent grammars. For instance, prece- dence monotonicity requires ... derivation information itself is not used to assist the algorithm. Even in (Beaven, 1992a), the derivation information is used simply to cache previous results to avoid exact re- computatio...

... corresponding extensions for context-free LR parsing. Section 2 discusses our notation. The algo- rithm for constructing the LR table is given in Section 3, and the automaton that operates on these ... very close to traditional LR parsing for context-free grammars. The construction of derived trees and the computation of features also become straightforward. 1 Introduction The...

Whereas the concen- tration of LF required to kill 50% of the cells (EC50) was estimated to be 4 · 10 )11 m, LF-K518E ⁄ E682G did not cause enough cell death under these conditions for ... MAPKs. Interestingly, increasing the LF concentration from 10 )11 m to 10 )10 m had a considerable effect on cell viability, but relatively minor effects on the phosphory- lation of the MAPK...

Coexpression of Pbx1a was ... HTH functions could be performed by both isoforms, although for antenna development only full-length HTH was sufficient. It may therefore be that Meis2e- like proteins are functional for s...
