So-Called Non-Subsective Adjectives
The interpretation of adjective-noun pairs plays a crucial role in tasks such as recognizing textual entailment. Formal semantics often places adjectives into a taxonomy which should dictate adjectives’ entailment behavior when placed in adjective-noun compounds. However, we show experimentally that the behavior of subsective adjectives (e.g. red) versus non-subsective adjectives (e.g. fake) is...
متن کاملHistone Acetylation in Conjugating
We have monitored histone acetylation during conjugation of the ciliated protozoan Tetrahymena thermophila using antibodies against the tetraacetylated form of H4 histone (Pfeffer, U., N. Ferrari, and G. Vidali. 1986. J. Biol. Chem. 261:2496-2498). During meiosis, the three prezygotic divisions, fertilization, and the first postzygotic division, micronuclei, do not contain highly acetylated for...
متن کاملConjugating plasmids are preferred targets for Tn7.
Most transposons display target site selectivity, inserting preferentially into sites that contain particular features. The bacterial transposon Tn7 possesses the unusual ability to recognize two different classes of target sites. Tn7 inserts into these classes of target sites through two transposition pathways mediated by different combinations of the five Tn7-encoded transposition proteins. I...
متن کاملMobile Digital Communications Using Phase Conjugating Arrays
A phase conjugation based method for full-duplex digital communications is discussed. The method uses a spatially confined and directive antenna pattern while a fullduplex digital communications link is maintained between moving platforms. The communications abilit~ of the array is based on processing the phase associated with the message and the phase associated with the platform’s motion sepa...
متن کامل-Carboxylic Acid-Conjugating Activity in Tomato Fruit
A new conjugate, 1 -(y-i-glutamylamino)cyclopropane-1 -carboxylic acid (CACC), of the ethylene precursor 1 -aminocyclopropane1 -carboxylic acid (ACC) i s identified. The only previously identified conjugate of ACC i s 1 -(malonylamino)cyclopropane-1 -carboxylic acid (MACC). CACC, not MACC, was the major conjugate formed by crude protein extracts of tomato (Lycopersicon esculentum Mil1 cv Ailsa ...
