Aspects of semantic interpretation, such as quan-tiier scoping and reference resolution, are often realised computationally by non-monotonic operations involving loss of information and destructive manipulation of semantic representations. The paper describes how monotonic reference resolution and scoping can be carried out using a revised Quasi Logical Form (QLF) representation. Semantics for ...

The aim was to compare the detection and quantification of smooth surface caries by KaVo DIAGNOdent and quantitative laser/light-induced fluorescence (QLF) using a laser and a lamp as two different light sources. On 40 premolar teeth extracted from adolescents, 71 non-cavitated approximal surfaces were assessed. For QLF, both mean and maximum fluorescence losses were registered. To provide a go...

We combine a large set of quasar luminosity function (QLF) measurements from the rest-frame optical, soft and hard X-ray, and nearand mid-infrared bands to determine the bolometric QLF in the redshift interval z = 0 − 6. Accounting for the observed distributions of quasar column densities and variation of spectral energy distribution (SED) shapes, and their dependence on luminosity, makes it po...

BACKGROUND Measurement of initial enamel erosion is currently limited to in vitro methods. Optical coherence tomography (OCT) and quantitative light-induced fluorescence (QLF) have been used clinically to study advanced erosion. Little is known about their potential on initial enamel erosion. OBJECTIVES To evaluate the sensitivity of QLF and OCT in detecting initial dental erosion in vitro. ...

Based on numerical simulations of galaxy mergers that incorporate black hole growth, we predict the faint end slope of the quasar luminosity function (QLF) and its evolution with redshift. Our simulations have yielded a new model for quasar lifetimes and light curves where the lifetime depends on both the instantaneous and peak luminosities of the quasar. This description motivates a new interp...

The purpose of this in vivo study was to assess the clinical screening performance a quantitative light-induced fluorescence (QLF) device detecting proximal caries primary molars. Fluorescence loss, red autofluorescence and simplified QLF score for (QS-proximal) were evaluated their validity molars compared bitewing radiography. Three hundred forty-four molar surfaces included study. Carious le...

Enamel microabrasion has become accepted as a conservative, nonrestorative method of removing intrinsic and superficial dysmineralization defects from dental fluorosis, restoring esthetics with minimal loss of enamel. However, it can be difficult to determine if restoration is necessary in dental fluorosis, because the lesion depth is often not easily recognized. This case report presents a met...

in zero acceptance number sampling plans, the sample items of an incoming lot are inspected one by one. the proposed method in this research follows these rules: if the number of nonconforming items in the first sample is equal to zero, the lot is accepted but if the number of nonconforming items is equal to one, then second sample is taken and the policy of zero acceptance number would be appl...

OBJECTIVE This study evaluated whether Quantitative Light-induced Fluorescence-Digital (QLF-D) can detect the levels of cariogenicity of dental microcosm biofilms by assessing the red fluorescence intensity. METHODS Dental microcosm biofilms were initiated from human saliva on bovine enamel discs. Biofilms with various levels of cariogenicity were then grown in artificial saliva supplemented ...

In this paper, the geometric distribution parameter is estimated under a type-I censoring scheme by means of Bayesian estimation approach. The Beta and Kumaraswamy informative priors, as well five loss functions are used for purpose. Expressions Bayes estimators risks derived Squared Error Loss Function (SELF), Quadratic (QLF), Precautionary (PLF), Simple Asymmetric (SAPLF), DeGroot (DLF) using...
