We present a model for inducing sentential argument structure, which distinguishes arguments from optional modifiers. We use this model to study whether representing an argument/modifier distinction helps in learning argument structure, and whether a linguistically-natural argument/modifier distinction can be induced from distributional data alone. Our results provide evidence for both hypotheses.

Modifier logics are considered as generalizations of "classiea1" modal logics. Thus modifier logics are soeanled multimodal logios. Multimodality means here that the basic logics are modal logics with graded modalities. The interpretation of modal operators is more generan, too. Leibniz's mottvating semantical ideas (see [8]. p. 20-21) givejustification to these generalizations. Semantics of ca...

Three binders of varying crude source, distillation, performance wax presence investigated. 1 H NMR demonstrated slight changes the relative proton distribution upon EPR supported an increase organic carbon-centred radicals short-term TOF-SIMS revealed SO x -, (OH) -containing compounds because Unde...

We explore the evolution of dominance at polymorphisms maintained either by overdominant selection or by migration-selection balance. At such balanced polymorphisms, heterozygotes remain at appreciable frequencies over long periods of time, allowing extensive modification of dominance to occur. The strength of selection favoring a modifier of dominance is roughly proportional to the probability...

Temperature programmed desorption methods have been used to probe the enantioselectivity of achiral Cu(100), Cu(110), and Cu(111) single crystal surfaces modified by chiral organic molecules including amino acids, alcohols, alkoxides, and amino-alcohols. The following combinations of chiral probes and chiral modifiers on Cu surfaces were included in this study: propylene oxide (PO) on L-alanine...

A model of mutation rate evolution for multiple loci under arbitrary selection is analyzed. Results are obtained using techniques from Karlin (Evolutionary Biology, vol. 14, pp. 61-204, 1982) that overcome the weak selection constraints needed for tractability in prior studies of multilocus event models.A multivariate form of the reduction principle is found: reduction results at individual loc...
