introduction: the purpose of this study was to determine the in vitro antimicrobial ability against entrococcus (e.) faecalis of triple antibiotic paste and its components compared with calcium hydroxide mixtures . materials and methods: an agar well diffusion assay and mic method were used to determine the efficacy of the experimental medicaments in removing e. faecalis. medicaments were divid...

Pairwise nonisomorphic directed and hybrid triple systems can be generated by, respectively, directing and ordering twofold triple systems and using the automorphisms of the twofold triple systems for isomorph rejection. Using this approach directed triple systems of order up to 10 and hybrid triple systems of order up to 9 are classified. In particular, it turns out that the number of nonisomo...

We address the problem of automatically constructing a thesaurus by clustering words based on corpus data. We view this problem as that of estimating a joint distribution over the Cartesian product of a partition of a set of nouns and a partition of a set of verbs, and propose a learning algorithm based on the Minimum Description Length (MDL) Principle for such estimation. We empirically compar...

In this paper we describe a Parallel Performance Estimator suitable for the comparative evaluation of parallel algorithms. The Esti-mator is designed for SPMD programs written in either C or FORTRAN. Simulation is used to produce estimates of execution times for varying numbers of processors and to analyse the communication overheads. Results from the estimator are compared with actual results ...

Wavelet shrinkage methods have been very successful in nonparametric regression. The most commonly used wavelet procedures achieve adaptivity through term-by-term thresholding. The resulting estimators attain the minimax rates of convergence up to a logarithmic factor. In the present paper, we propose a block thresholding method where wavelet coef-cients are thresholded in blocks, rather than i...

We consider local polynomial regression estimation for nite population totals in two-stage element sampling. The estimators are linear combinations of es-timators of cluster totals with weights that are calibrated to known control totals. The estimators are asymptotically design-unbiased and consistent under mild assumptions. We provide a consistent es-timator for the design mean squared error ...

We deene the kth order estimate of an extreme quantile q n , n < 1=n, and study its consistency as n ! 0 and n ! 1 for classes of distributions in the maximum domain of attraction of Gumbel. We show that the consistency of the kth order estimate imposes conditions on n in most cases, but does not depend on its order k. As a particular case, we obtain that, when the ET estimate (which is also th...

A method is presented for the automatic extraction of voice source parameters from speech. An automatic i n-verse filtering algorithm is used to obtain an esti mate of the glottal flow signal. Subsequently, an LF-model [1] is fitted to the glottal flow signal. In the current article we will focus on the improvement of the automatic fit procedure. To keep track of the performance of the fit proc...

The do-calculus was developed in 1995 to facilitate theidentification of causal effects in non-parametric mod-els. The completeness proofs of [Huang and Valtorta,2006] and [Shpitser and Pearl, 2006] and the graphi-cal criteria of [Tian and Shpitser, 2010] have laid thisidentification problem to rest. Recent explorations un-veil the usefulness of the do-calculus in three ...

A novel method unifying viewer and model centered approaches for representing structurally complex D objects like human faces is presented The uni ed D frequency domain representation called Volumet ric Iconic Spectral Signatures V ISS encapsulates both the spatial structure of the object and a contin uum of its views in the same data structure An ex tension of the Projection Slice Theorem is u...
