The generalized conjunction/disjunction function (GCD) is a continuous logic function of two or more variables that integrates conjunctive and disjunctive properties in a single function. It is used as a mathematical model of simultaneity and replaceability of inputs. Special cases of this function include the full (pure) conjunction, the partial conjunction, the arithmetic mean, the partial di...

We show that existing methods for training preposition error correction systems, whether using well-edited text or error-annotated corpora, do not generalize across very different test sets. We present a new, large errorannotated corpus and use it to train systems that generalize across three different test sets, each from a different domain and with different error characteristics. This new co...

This paper introduces the problem of predicting semantic relations expressed by prepositions and develops statistical learning models for predicting the relations, their arguments and the semantic types of the arguments. We define an inventory of 32 relations, building on the word sense disambiguation task for prepositions and collapsing related senses across prepositions. Given a preposition i...

root resorption (rr) is defined as the loss of dental hard tissues because of clastic activity inside or outside of tooth the root. in the permanent dentition, rr is a pathologic event; if untreated, it might result in the premature loss of the affected tooth. several hypotheses have been suggested as the mechanisms of root resorption such as absence of the remnants of hertwig's epithelial root...

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 ...

Introduction: Treatment with megavoltage electron beams is ideal for irradiating superficial tumors because of their limited range in tissues. However, for electron treatment of extended areas, such as the chest wall, two or more adjacent fields can be used. Abutment of these fields may lead to significant dose in homogeneities in the junction region. The aim of this study is to offer a new met...
