The genome copy numbers of seven crenarchaeal species of four genera have been reported. All of them are monoploid and thus this seems to be a characteristic feature of Crenarchaeota. In stark contrast, none of six species representing six euryarchaeal genera is monoploid. Therefore Euryarchaea are typically oligoploid or polyploidy and their genome copy numbers are tightly regulated in respons...

Durative forces are introduced to Finite State Temporality (the application of Finite State Methods to Temporal Semantics). Punctual and durative forces are shown to have natural representations as fluents which place certain constraints on strings. These forces are related to previous work on stative explanations of aspectual classification. Given this extended ontology, it is shown how type c...

Although the uncovered set has occupied a prominent role in social choice theory, its exact shape has never been determined in a general setting. This paper calculates the uncovered set when actors have pork barrel, or purely distributive, preferences, and shows that in this setting nearly the entire Pareto set is uncovered. The result casts doubt on the usefulness of the uncovered set as a gen...

Major casts, for example, the anchor persons or reporters in news broadcast programs and principle characters in movies play an important role in video, and their occurrences provide good indices for orgnnizing and presenting video content. This paper describes a new approach for automatically generating the list of majo r casts in a video sequence based on multiple modalities, specfically, bot...
