The paper contains two results on the equivalence classes of block Jacobi matrices: first, that the Jacobi matrix of type 2 in the Nevai class has An coefficients converging to 1, and second, that under an L1-type condition on the Jacobi coefficients, equivalent Jacobi matrices of types 1, 2 and 3 are pairwise asymptotic.

This paper attempts to compare the main features of random and highly ordered gold nanostructure arrays (NSA) prepared by thermally annealed island film and nanoimprint lithography (NIL) techniques, respectively. Each substrate possesses different morphology in terms of plasmonic enhancement. Both methods allow such important features as spectral tuning of plasmon resonance position depending o...

This study examined correlates of objectively measured physical activity (PA) in a diverse sample of preschool children (age 3-5 years; n = 331). Accelerometer min x hr-1 of moderate-to-vigorous physical activity (MVPA) and nonsedentary activity (NSA) were the outcome measures. Correlations among potential correlates and PA ranged from r= -0.12-0.26. Correlates in the final MVPA model were age,...

We prove that every graph of girth at least five which admits an embedding in the Klein bottle is 3-colorable. This solves a problem raised by Woodburn, and complements a result of Thomassen who proved the same for projective planar and toroidal graphs. 15 July 1998, Revised 26 April 2004. To appear in J.

Femoral stem version has a major influence on impingement and early post-operative stability after total hip arthroplasty (THA). The main objective of this study was to evaluate the validity of a novel radiological method for measuring stem version. Anteroposterior (AP) radiographs and three-dimensional CT scans were obtained for 115 patients (female/male 63/72, mean age 62.5 years (50 to 75)) ...

Aim: This study aims to determine the gender differences in hip joint functional anthropometric measurement values Turkish adults.Materials and Methods: Digital pelvis anterior-posterior radiographs of 300 randomly selected patients were analyzed. In these radiographs, reference lines drawn femoral neck-shaft angle (NSA), rotation center (HRC), abductor moment arm (AMA), body weight (BMA) calcu...

Objectives: This paper presents a new hybrid ACO-NSA algorithm for the automatic test data generation problem with path coverage as an objective function. Method: In it, at first instance, (detectors) are generated ant colony optimization (ACO), and then set (detector set) has been refined by negative selection (NSA) Hamming distance. Findings: The algorithm’s performance is tested on several b...

Metal-analyte interaction is a type of nonspecific adsorption (NSA) that occurs mainly between acidic analytes and active adsorptive sites present in the metal surfaces fluidic path any chromatographic system. NSA represents challenge since it may lead to poor peak shape, low recovery, performance from high liquid chromatography (HPLC) As result, many solutions circumvent mitigate this secondar...
