background and aims. previous researches, conducted mostly on extracted teeth, have shown that efficacy of calculus removal decreases with increasing pocket depth, but there is still a lack of clinical studies concerning the correlation be-tween residual calculus and varying pocket depths. the objective of the present clinical study was to assess the efficiency of mechanical tooth depuration by...

We define a language whose type system, incorporating session types, allows com-plex protocols to be specified by types and verified by static typechecking. A ses-sion type, associated with a communication channel, specifies the state transitionsof a protocol and also the data types of messages associated with transitions; thustypechecking can verify both correctness of indi...

Functional logic languages with a sound and complete opera tional semantics are mainly based on narrowing Due to the huge search space of simple narrowing steadily improved narrowing strategies have been developed in the past Needed narrowing is currently the best nar rowing strategy for rst order functional logic programs due to its opti mality properties w r t the length of derivations and th...

Although there are many excellent ways presenting the principle of the classical calculus, the novel presentations probably leads most naturally to the development of the non-Newtonian calculus. The important point to note is that the non-Newtonian calculus is a self-contained system independent of any other system of calculus. Since this self-contained work is intended for a wide audience, inc...

In previous work we have developed the scheme of indeenite L-constraint databases where L, the parameter, is a rst-order constraint language. This scheme extends the constraint database proposal of Kanellakis, Kuper and Revesz to include in-deenite (or uncertain) information in the style of Imielinski and Lipski. In this paper we study the complexity of query evaluation in an important instance...

Logic and databases have gone a long way together since the advent of relational databases Already the rst basic query languages for relational databases beside relational algebra tuple calculus and domain calculus are actually a subset of rst order predicate logic Furthermore logic proved to be very adequate for establishing a sound theory for rela tional databases When attempts were made to i...

Gomez, Avellana and Nicolas (2) studied early leprosy among Culion children and mentioned a few instances of disappearance, without treatment, of lesions that were either negative or positive bacteriologically. There is no subsequent record of those cases, and the period of their observations covered only about nine months. Lara and de Vera (3), in 1935, called attention to the occurrence in 7 ...
