We observe that every rst-order logic formula over the untyped version of some many-sorted vocabulary is equivalent to a union of manysorted formulas over that vocabulary. This re...
We introduce a typed feature logic system providing both universal implicational principles as well as definite clauses over feature terms. We show that such an architecture suppo...
This paper considers three assumptions conventionally made about signatures in typed feature logic that are in potential disagreement with current practice among grammar developer...
ome this restriction, we develop so-called loose domains which abstract over several precise domains. Similar to the relation between supertypes and subtypes, we get a relation bet...
In this paper evidence is presented that supports the hypothesis that amino acid usage bias is a fundamental property of viral genome types. Clues to the biological basis for the o...
