A class of semi-recursive kernel type estimates of functions depending on multivariate density functionals and their derivatives is considered. The piecewise smoothed approximations of these estimates are proposed. The convergence with probability one of the estimates is proved. The main parts of the asymptotic mean square errors of the estimates are found. The examples of estimation of the pro...

We sought to determine the short- and long-term prognoses among 'marginal-risk' non-small cell lung cancer patients who have a predicted postoperative- (ppo) forced expiratory volume in the first second (FEV1) of 30-60% and/or a ppo-diffusing capacity of the lung for carbon monoxide (DLCO) of 30-60%. The present study included 73 'marginal-risk' and 318 'normal-risk' patients who underwent anat...

background and aims. the majority of failures in class ii amalgam restorations occur in the first primary molar teeth; in addition, use of compomer instead of amalgam for primary molar teeth restorations is a matter of concern. the aim of the present study was to compare the success rate of class ii compomer and amalgam restorations in the first primary molars. materials and methods. a total of...

purpose: the aim of this study was to evaluate the effect of two gingival finishing lines (90° shoulder and deep chamfer) on the marginal fitness of two types of full anatomic all-ceramic crowns; zirconia crowns (zikonzhan) and glass ceramic crowns (ips e-max cad) milled with cad/cam system. materials and methods: two dentoform teeth of left maxillary first molar were prepared with chamfer fini...

PURPOSE The aim of this clinical retrospective study was to evaluate the clinical quality, success rate, and estimated survival rate of anterior veneers made of silicate glass-ceramic in a long-term analysis of up to 20 years. MATERIALS AND METHODS Anterior teeth in the maxillae and mandibles of 84 patients (38 men, 46 women) were restored with 318 porcelain veneer restorations between 1987 a...

PURPOSE The aims of this randomized-controlled clinical trial were to compare marginal and internal adaptation of all-ceramic crowns fabricated with CAD/CAM and heat-pressed (HP) techniques before luting and to evaluate the clinical outcomes at baseline and at 6, 12, and 24 months after luting. MATERIALS AND METHODS Fifteen CAD/CAM (CC) and 15 HP all-ceramic crowns were placed in 15 patients....

BACKGROUND There is wide regional variation in the predominant treatment for unruptured cerebral aneurysms. We investigated the association of elective surgical clipping and endovascular coiling with mortality, readmission rate, length of stay, and discharge to rehabilitation. METHODS AND RESULTS We performed a cohort study involving patients with unruptured cerebral aneurysms, who underwent ...

We consider a two-dimensional semimartingale reflecting Brownian motion (SRBM) in the nonnegative quadrant. The data of the SRBM consists of a two-dimensional drift vector, a 2×2 positive definite covariance matrix, and a 2×2 reflection matrix. Assuming the SRBM is positive recurrent, we are interested in tail asymptotic of its marginal stationary distribution along each direction in the quadra...

There is currently no consensus regarding the optimal radiation volume for high-grade glioma (HGG). The brain volume irradiated is associated with the extent of radiation neurotoxicity. When reducing the treatment volume, the risk of geographic tumor miss should be considered. In such cases, the recurrence patterns and, particularly, the rate of marginal tumor recurrence, are important indices ...
