The effects of a female-specific meiotic mutation, altered disjunction (old: 361), are described. Although old females show normal levels of meiotic exchange, sexand 4th-chromosome nondisjunction occurs at an elevated level. A large proportion of the nondisjunction events is the result of nonhomologous disjunction of the sex and 4th chromosomes. These nonhomologous disjunction events, and proba...

English and Japanese differ in the interpretation of disjunction in simple negative sentences. However, the contrast vanishes in a ‘covert’ negative entailment created by the focus operator (only/dake). Experiments with English/Japanese children reveal their sensitivity to the interpretive interaction of disjunction with the focus operator, despite their divergent linguistic input. Our results ...

We investigate the complexity of satisfaction problems in modal description logics without disjunction between formulae. It is shown that simulation of disjunction in the class of all models of these logics is possible, so that the complexity remains same no matter the logics is with or without disjunction of formulae. However, the omission of disjunction, in the class of the models based on th...

We present two schemes for compiling disjunctions of nite domain constraints, where disjunction is treated as constructive. In the rst scheme each disjunction is compiled to a set of indexicals, i.e. a set of range functions computing domain restrictions, such that the evaluation of the indexicals maintains a weak form of consistency of the disjunction. The second scheme is based on constraint ...
