Unification and Grammatical Theory
(Cascadilla Press, 1986)
This paper informally presents a new view of grammar that has emerged from a number of distinct but related lines of investigation in theoretical and computational linguistics. Under this view, many current linguistic ...
A simple reconstruction of GPSG
(Association for Computational Linguistics, 1986)
Like most linguistic theories, the theory of generalized phrase structure grammar (GPSG) has described language axiomatically, that is, as a set of universal and language-specific constraints on the well-formedness of ...
Asymmetric Melting and Freezing Kinetics in Silicon.
(American Physical Society, 1986)
We report measurements of the melting velocity of amorphous Si relative to that of (100) crystalline Si. These measurements permit the first severe experimental test of theories describing highly nonequilibrium freezing ...
Solute Trapping in Silicon by Lateral Motion of {111} Ledges
(American Physical Society, 1986)
The orientation dependence of the nonequilibrium partition coefficient of Bi in Si at constant solid-liquid interface velocity has been measured. The partition coefficient, measured with pulsed-laser melting techniques on ...
Quantized Layer Growth at Liquid-Crystal Surfaces
(American Physical Society, 1986)
We report x-ray reflectivity measurements on the free surface of dodecylcyanobiphenyl (12CB) at the isotropic to smectic-A phase transition. At about \(10^{\circ}C\) above \(T_{IA}\), smectic-A-like ordering develops at ...
X-Ray Studies of Transitions between Nematic, \(Smectic-A_1, -A_2, and -A_d\) Phases
(American Physical Society, 1986)
We report high-resolution x-ray scattering measurements of the critical fluctuations in mixtures of hexylphenyl cyanobenzoyloxy benzoate \((DB_6)\) and terephtal-bis-butylaniline (TBBA). The phase sequence exhibited on ...
Attention, Intentions, and the Structure of Discourse
(Association for Computational Linguistics/MIT, 1986)
In this paper we explore a new theory of discourse structure that stresses the role of purpose and processing in discourse. In this theory, discourse structure is composed of three separate but interrelated components: the ...
Chemistry of OH in remote clouds and its role in the production of formic acid and peroxymonosulfate
(Wiley-Blackwell, 1986)
The chemistry of OH in a remote nonprecipitating tropical cloud is studied with a coupled gas-phase and aqueous-phase chemical model. The model takes into account the radial dependence of the concentrations of short-lived ...
The \(H_2SO_4-HNO_3-NH_3\) system at high humidities and in fogs: 2. Comparison of field data with thermodynamic calculations
(Wiley-Blackwell, 1986)
Concentrations of HNO(g) and NH(g) determined in the field were compared to predictions from aerosol equilibrium models. The products of HNO(g) and NH(g) concentrations measured under cool and humid nonfoggy conditions ...
Transport and oxidation of SO2 in a stagnant foggy valley
(Elsevier BV, 1986)
The fate of SO2 emitted in the San Joaquin Valley of California under stagnant foggy conditions was determined by the release of an inert tracer and the concurrent monitoring of SO2 and SO42− concentrations. At night, SO2 ...
