Discovering Veiled Unsatisfiable Xpath Queries
The satisfiability problem of queries is an important determinant in query optimization. The application of a satisfiability test can avoid the submission and the unnecessary evaluation of unsatisfiable queries, and thus save processing time and query costs. If an XPath query does not conform to constraints in a given schema, or constraints from the query itself are inconsistent with each other...
متن کاملImmature Dengue Virus: A Veiled Pathogen?

Furthermore, it has been recently described that the rates of prM antibody responses are significantly higher in patients with secondary infection compared to those with primary infection. This suggests that imma...
متن کاملNegative Staining of Thinly Spread Cells and Associated Virus
The first demonstration of intracytoplasmic virus by negative staining was that of Horne and Nagington (9) who subjected poliovirus-infected cells to freezing and thawing and negatively stained a suspension of the fragments. Dales (5) examined the attachment of some viruses to the cell surface by the negative staining of whole mounts of cells subjected to osmotic shock. Whittaker and Horne (15)...
متن کاملOpaque Predicates, Veiled Sets and Their Logic
Motivated by considerations in the foundations of quantum mechanics and inspired by the literature on vague predicates, we introduce the concept of an opaque predicate. While in the case of vague predicates there is a kind of indeterminacy with respect to the predicate, in the sense that the vagueness concerns whether a well-determined object satisfies it or not, in the case of opaque predicate...
