Particles fullfill several distinct central roles in the Japanese language. They can mark arguments as well as adjuncts, can be functional or have semantic functions. There is, however, no straightforward matching from particles to functions, as, e.g., 'ga' can mark the subject, the object or the adjunct of a sentence. Particles can cooccur. Verbal arguments that could be identified by particles can be eliminated in the Japanese sentence. And finally, in spoken language particles are often omitted. A proper treatment of particles is thus necessary to make an analysis of Japanese sentences possible. Our treatment is based on an empirical investigation of 800 dialogues. We set up a type hierarchy of particles motivated by their subcategorizational and modificational behaviour. This type hierarchy is part of the Japanese syntax in VERBMOBIL.
Abstract: The measured particle ratios in central heavy-ion collisions at RHIC-BNL are investigated within a chemical and thermal equilibrium chiral SU(3) Ã É approach. The commonly adopted non-interacting gas calculations yield temperatures close to or above the critical temperature for the chiral phase transition, but without taking into account any interactions. In contrast, the chiral SU(3) model predicts temperature and density dependent effective hadron masses and effective chemical potentials in the medium and a transition to a chirally restored phase at high temperatures or chemical potentials. Three different parametrizations of the model, which show different types of phase transition behaviour, are investigated. We show that if a chiral phase transition occured in those collisions, freezing of the relative hadron abundances in the symmetric phase is excluded by the data. Therefore, either very rapid chemical equilibration must occur in the broken phase, or the measured hadron ratios are the outcome of the dynamical symmetry breaking. Furthermore, the extracted chemical freeze-out parameters differ considerably from those obtained in simple non-interacting gas calculations. In particular, the three models yield up to 35 MeV lower temperatures than the free gas approximation. The inmedium masses turn out to differ up to 150 MeV from their vacuum values.
A feature of the Northern Iroquoian languages is their especially rich inventory of particles. This paper is concerned with one particle in the Cayuga language which has a widespread distribution and performs a broad range of apparently unrelated functions. The particle ne:' is commonly .translated as 'it is/that is', 'this' or ' that'. In other instances it is translated as predominant stress, or is simply omitted in the translation. The particle can occur in almost any syntactic or semantic environment, but it is not obligatory in any context. The various functions that have been suggested in the literature include indication of declarative mood and assertion, marking of emphasis, focus or contrast, and expression of predicative and deictic force. I argue that the particle ne:' can be described successfully if its distribution is considered from a wider perspective, taking into account discourse structure and variation in scope. Its analysis as a focus marker can account for the variety of apparently unrelated functions. The analysis is based on a detailed study of the particle' s distribution in spoken language using a database of five Cayuga texts by four different speakers, including three narratives, one procedural text and a children 's version of a ceremonial text.
