Movement Without Boundaries

Black holes without boundaries

We discuss some of the drawbacks of using event horizons to define black holes and suggest ways in which black holes can be described without event horizons, using trapping horizons. We show that these trapping horizons give rise to thermodynamic behavior and possibly Hawking radiation too. This raises the issue of whether the event horizon or the trapping horizon should be seen as the true bou...

Narrative Intelligence Without (Domain) Boundaries

Narrative Intelligence (NI) can help computational systems interact with users, such as through story generation, interactive narratives, and believable virtual characters. However, existing NI techniques generally require manually coded domain knowledge, restricting their scalability. An approach that intelligently, automatically and economically acquires script-like knowledge in any domain wi...

Fuel movement along grain boundaries in ice

Knowledge about movement of hydrocarbon-based fuels in ice is relevant to marine and terrestrial fuel spills in polar regions, and to the dispersion of hydrocarbon-based drilling fluids used to maintain lithostatic pressure in deep ice coring projects. The latter is of concern from both environmental and sample integrity aspects, particularly for projects that plan to sample deep subglacial env...

French Clitic Movement Without Clitics or Movement

The French clitic system has posed a persistent challenge to transformational syntactic analysis, which has never produced a successful account of problems such as clitic ordering. Lexicalist alternatives, however, have never been reconciled with the full range of familiar problems and the growing body of known lexical idiosyncracies. We present a lexicalist treatment of the French clitic syste...
