the aim of this study was to determine the effect of trenched zirconia bar on the von mises stress distribution of ips -empress ii core ceramics.the three-dimensional model including a three-unit bridge from the second premolar to the second molar was designed. the model was reinforced with zirconia bar (zb), zirconia bar with vertical trench (vzb) and zirconia bar with horizontal trench (hzb) ...

It is well known that members of families of polynomials, that are orthogonal with respect to an inner product determined by a nonnegative measure on the real axis, satisfy a three-term recursion relation. Analogous recursion formulas are available for orthogonal Laurent polynomials with a pole at the origin. This paper investigates recursion relations for orthogonal rational functions with arb...

Hyperinsulinemia, a major indicator of insulin resistance, may exert its influence on the risk of coronary artery disease partially through disturbances of the hemostatic system. The relations of fasting insulin concentrations with the degree of coronary atherosclerosis, other coronary risk factors (including some markers of the insulin resistance syndrome such as body mass index and triglyceri...

THIS STUDY invesrigared the order of acquisition of phonological sensitivity skills among preschool and kinderganen children. Phonological sensitiviiy was examined in terms of four lc:vels of linguistic coniplexit\' (words, syllables, onsets and rimes, phonemes) across four levels of task complexity (blending detection, elision detection, blending, and elision). Participants were 947 twoto five...

This note is a generalization and improved interpretation of the main result of Karni and Schmeidler (An Expected utility theory for state-dependent preferences. Working paper no. 48-80 of the Foerder Institute for Economic Research, Faculty of Social Sciences, Tel AvivUniversity, 1980). A decision-maker is supposed to possess a preference relation on acts and another preference relation on sta...

Consider a countable group Γ acting ergodically by measure preserving transformations on a probability space (X,μ), and let RΓ be the corresponding orbit equivalence relation on X. The following rigidity phenomenon is shown: there exist group actions such that the equivalence relation RΓ on X determines the group Γ and the action (X,μ,Γ) uniquely, up to finite groups. The natural action of SLn(...

Formulas governing fixed orbital hardnesses and their relation to the hardness kernel are derived. It is shown how the orbital hardness matrix and its inverse matrix, the orbital softness matrix, may thus be directly calculated, and then the total chemical hardness, softness, and electronegativity of a molecular species. These quantities are calculated for the molecule HCN, using Dirac exchange...

Csiszár’s f -divergence of two probability distributions was extended to the quantum case by the author in 1985. In the quantum setting, positive semidefinite matrices are in the place of probability distributions and the quantum generalization is called quasi-entropy, which is related to some other important concepts as covariance, quadratic costs, Fisher information, Cramér-Rao inequality and...

Exploitation of architectural support for Prolog-like languages takes one of two main paths: compiler-based or interpreter-based. The former scheme enforces the transformation from a logic program to a set of instructions tailored for Prolog to accommodate the instruction-driven von Neumann processor, while the latter implements a complicated inference procedure as a microinterpreter to realize...

Diese Arbeit untersucht das Phänomen der Graduierung im Bereich der lexikalischen Semantik. Im lexikalischen System einer Sprache existieren Wörter, die durch verschiedene Grade eines Merkmals kontrastieren und eine besondere lexikalisch-semantische Gruppe konstituieren. Die Relation zwischen den Elementen derartiger Gruppen wird als Graduonymie bezeich net. Diese Studie stellt Überlegungen zu...
