Recently a new technique in the harmonic analysis on symmetric spaces was suggested based on certain remarkable representations of affine and double affine Hecke algebras in terms of Dunkl and Demazure operators instead of Lie groups and Lie algebras. In the classic case (see [O,H,C5]) it resulted (among other applications) in a new theory of radial part of Laplace operators and their deformati...

d three such methods for their ability to predict the etectability of objects in natural backgrounds: a i Cortex transform model with within-channel mask ng, a Contrast Sensitivity filter model, and digital m image difference metrics. Each method was imple ented with three different summation rules: the n w root mean square difference, Minkowski summatio ith a power of 4, and maximum difference...

In the first part of the paper kernels are constructed which meromorphically extend the Macdonald-Koornwinder polynomials in their degrees. In the second part of the paper the kernels associated with rank one root systems are used to define nonsymmetric variants of the spherical Fourier transform on the quantum SU(1, 1) group. Related Plancherel and inversion formulas are derived using double a...

Background For dental implant planning in maxillary posterior region, it is essential to know their relationship with maxillary sinus. Maxillary posterior teeth affected by chronic periodontitis usually have a poor prognosis, ultimately leading to tooth loss. Following tooth loss, significant bone resorption occurs resulting in compromised remaining bone support for dental implant placement. ...

This study presents a new method for correcting the six degrees of freedom motion-induced error in ZephIR 300 floating Doppler Wind-LiDAR-derived data, based on Robust Adaptive Unscented Kalman Filter. The filter takes advantage known Wind-LiDAR (FDWL) dynamics, velocity–azimuth display algorithm, and wind model describing LiDAR-retrieved vector without motion influence. estimates corrected by ...

The normal range for aortic root diameters employing the echocardiographic continuous recording technique was determined in 159 adult subjects without aortic valve disease or hypertension. In order to evaluate the accuracy of this noninvasive technique, the aortic root diameters as measured by ultrasound before operation in 31 patients with aortic valve disease were compared with their respecti...

Many source localization methods neglect the anisotropic conductivity of brain tissues, although it has a big influence on the localization problem. In this study, we evaluated the dipole localization error due to neglecting the anisotropic properties of the conductivity in a realistic head model (built from T1 and diffusion tensor MRI) calculated using a FDM method. Results show that the mean ...

Objective: The aim of this study was to compare the diagnostic efficacy of an electronic apex locator (EAL) and radiovisigraphy (RVG) in working length (WL) determination. Materials and Methods: This study was performed on Single-rooted maxillary/mandibular teeth requiring root canal treatment. After administration of local anesthesia, the teeth were isolated and the pulp cavities were accessed...
