On Parsing LL-Languages

Usually, a parser for an LL(k)-grammar G is a deterministic pushdown transducer which produces a leftmost derivation for a given input string x 2 L(G). Ukkonen 5] has given a family of LL(2)-grammars proving that every parser for these grammars has exponential size. If we add to a parser the possibility to manipulate a constant number of pointers which point to positions within the constructed ...

Retraction Note: Human cathelicidin LL-37 enhance the antibiofilm effect of EGCG on Streptococcus mutans

BACKGROUND Streptococcus mutans forms biofilms as a resistance mechanism against antimicrobial agents in the human oral cavity. We recently showed that human cathelicidin LL-37 exhibits inhibitory effects on biofilm formation of S. mutans through interaction with lipoteichoic acid (LTA), but without antibacterial or biofilm dispersal abilities. (-)-Epigallocatechin gallate (EGCG) is the most ab...

A note on vague graphs

In this paper, we introduce the notions of product vague graph, balanced product vague graph, irregularity and total irregularity of any irregular vague graphs and some results are presented. Also, density and balanced irregular vague graphs are discussed and some of their properties are established. Finally we give an application of vague digraphs.

A note on lifting projections

Suppose $pi:mathcal{A}rightarrow mathcal{B}$ is a surjective unital $ast$-homomorphism between C*-algebras $mathcal{A}$ and $mathcal{B}$, and $0leq aleq1$ with $ain  mathcal{A}$. We give a sufficient condition that ensures there is a proection $pin mathcal{A}$ such that $pi left( pright) =pi left( aright) $. An easy consequence is a result of [L. G. Brown and G. k. Pedersen, C*-algebras of real...
