In using pooling designs to identify clones containing a specific subsequence called positive clones, sometimes there exist nonpositive clones which can cancel the effect of positive clones. Various models have been studied which differ in the power of cancellation. Although the various models pose interesting mathematical problems, and ingenious constructions of pooling designs have been propo...

The present study examined how achievement goals affect retrieval-induced forgetting. Researchers have suggested that mastery-approach goals (i.e., developing one's own competence) promote a relational encoding, whereas performance-approach goals (i.e., demonstrating one's ability in comparison with others) promote item-specific encoding. These different encoding processes may affect the degree...

Randomisation is a method to test the statistical significance of a symbolic rule; it is, however, very expensive. In this paper we present a sequential randomisation test which dramatically reduces the number of steps needed for a conclusion.

Distributive lattices are well known to be precisely those lattices that possess cancellation: x ∨ y = x ∨ z and x ∧ y = x ∧ z imply y = z. Cancellation, in turn, occurs whenever a lattice has neither of the 5-element lattices M3 or N5 as sublattices. In this paper we examine cancellation in skew lattices, where the involved objects are in many ways lattice-like, but the operations ∧ and ∨ no l...

CT-based dental imaging for implant planning and surgical guidance carries both clinical and radiographic information for implant positioning as far as trajectory, depth and distribution. The significance of accurate planning and surgical guidance as it pertains to critical anatomical landmarks, such as the mandibular canal, maxillary sinus and adjacent teeth, cannot be overstated. This case re...

It is not enough known about differences in cost to provide anesthesia care for different surgical disciplines. Aims: In attention to check possibility for rationalization, study aims are: identification, measuring, economically evaluation and analyzing the costs of anesthesia care for different surgical disciplines.Methods: In this retrospective study, the authors determined the direct costs (...

We present a class of Ansätze for the up and down quark mass matrices which leads approximately to: |Vus| ∼ √ md/ms, |Vcb| ∼ ms/mb, and |Vub/Vcb| ∼ √ mu/mc. Sizes of the Kobayashi-Maskawa matrix elements are controlled solely by quark mass ratios. In particular, we introduce no other small parameter and our results do not rely on delicate cancellation.

The aim of the research was to determine construct validity and reliability for two questionnaires (Athlete Engagement Questionnaire-AEQ and Athletic Identity Measurement Scale-AIMS), applied on elite Croatian athletes-sprinters, as well as the correlations among the dimensions in these measuring instruments. Then, we have determined the differences in the dimensions of sport engagement and spo...
