OF THE DISCUSSION. DB. MARTIN L. HOLBROOK: In listening to the able and interesting lecture of Prof. Cope, I could not help wishing that he had given us more detailed information about the personal life of Mr. Wallace. Knowledge of the personal characteristics of a writer often greatly helps us to an understanding of his thought and to a due appreciation of the value of his opinions. From a fri...

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 ...

lL - 8 induces T cell chemotaxis , suppresses lL - 4 , and up - regulates lL - 8 production by CD 4 T cells

Interleukin-8 (IL-8), a neutrophil-activatbig cytokine, also activates certain T cell functions such as chemotaxis. We additionally find (n 6) that recombinant (rIL-8; 1-100 ng/ml), when added to 24 h culture of human CD4 T cells, suppressed the spontaneous production of IL-4 (50-85%). Steady state production of IL-4 was typically around 30 pg/nil, determined by use of a solidphase immunoabsorb...

Linear Ll Auchli Semantics

Dedicated to the memory of Moez Alimohamed Abstract We introduce a linear analogue of LL auchli's semantics for intuitionistic logic. In fact, our result is a strengthening of LL auchli's work to the level of proofs, rather than provability. This is obtained by considering continuous actions of the additive group of integers on a category of topological vector spaces. The semantics, based on fu...
