This paper presents a technique for further applications of deductive databases in the eld of natural language processing. Although there were enormous research eeorts on analyzing the semantics of natural languages (NL), especially using Montague grammars (PTQ) for Prolog, corresponding programs for deductive databases are still missing, since range restriction is required in nearly all deduct...

Background The role of calcium in physiological phenomenona such as sperm acrosome reaction and hyper-activation has been well known. Calcium ionophore A23187 is routinely used for induction of acrosome reaction in mammalians sperm. Therefore, we decided to evaluate the effect of calcium ionophore A23187 on the sperm hyper-active motility patterns. MaterialsAndMethods Ten semen samples from ind...

Modular deductive veri cation of software systems is a complex task: the user has to put a lot of e ort in writing module speci cations that t together when verifying the system as a whole. In this paper, we propose a combination of deductive veri cation and software bounded model checking (SBMC), where SBMC is used to support the user in the speci cation and veri cation process, while deductiv...

microglia is the effector cell of the innate immune system in central nervous system (cns). these cells mediate inflammatory responses in injuries. besides external factors, microglial function is also controlled by internal factors, including epigenetic regulations. mechanisms of epigenetic regulation mainly consist of dna methylation, histone modifications and use of non-coding rnas. recent s...

in this paper, we aresupposed to introduce the definitions of n-fold commutative, andimplicative hyper k-ideals. these definitions are thegeneralizations of the definitions of commutative, andimplicative hyper k-ideals, respectively, which have been definedin [12]. then we obtain some related results. in particular wedetermine the relationships between n-fold implicative hyperk-ideal and n-fold...

Outer joins are extended relational algebra operations intended to deal with unknown information represented with null values. This work shows an approach to embed both null values and outer join operations in the deductive database system DES (Datalog Educational System), which uses Datalog as a query language. This system also supports SQL, where views and queries are compiled to Datalog prog...

We report on a case study in using logical frameworks to support the formalization of programming calculi and their application to deduction-based program synthesis. Within a conservative extension of higher-order logic implemented in the Isabelle system, we derived rules for program development that can simulate those of the deductive tableau proposed by Manna and Waldinger. We have used the r...

As a step toward automatic circuit understanding, we have developed a method for parsing circuit topology in a deductive system called Duck. A circuit is viewed as a sentence and its elements as words. Generating circuits with specific functions is represented by deductive rules analogous to definite clause grammars. Using those rules, an object circuit is decomposed into a parse tree of functi...

This paper proposes to answer some questions concerning economy in computation and language by giving a very compact set of deductive rules (based on the so-called Lambek calculus, enriched with an exchange modality) which embodies all the properties of Minimalist Grammars (Stabler, 15]). move is replaced by a logical operation, very similar in its eeects to Form Chain, technically known as the...
