Component-by-Component Construction of Good Lattice Rules with a Composite Number of Points

open access: yesJournal of Complexity, 2002
We develop algorithms to construct rank-1 lattice rules in weighted Korobov spaces of periodic functions and shifted rank-1 lattice rules in weighted Sobolev spaces of non-periodic functions.

Influence of in vitro irrigation protocols on root canal treatment for bond strength to enamel and coronary dentin

open access: yesSaudi Endodontic Journal, 2021
Introduction: The purpose of this study was to evaluate the effects of different concentrations of chitosan solution used as a final rinse after root canal treatment on the shear bond strength of composite resin to enamel and coronary dentin.

Determination of the Optimum formula for Composite Motor Gasoline Octane Number Blending Enhancer

open access: yesJournal of Engineering, 2019
To decrease the dependency of producing high octane number gasoline on the catalytic processes in petroleum refineries and to increase the gasoline pool, the effect of adding a suggested formula of composite blending octane number enhancer to motor ...

Role of Fermion Exchanges in Statistical Signatures of Composite Bosons [PDF]

open access: yes, 2009
We study statistical signatures of composite bosons made of two fermions using a new many-body approach. Extending number-states to composite bosons, two-particle correlations as well as the dispersion of the probability distribution are analyzed.

Composite functional metasurfaces for multispectral achromatic optics [PDF]

open access: yesNature Communications, 2016
Nanostructured metasurfaces offer unique capabilities for subwavelength control of optical waves. Based on this potential, a large number of metasurfaces have been proposed recently as alternatives to standard optical elements.

Measuring Multipartite Concurrence with a Single Factorizable Observable [PDF]

open access: yes, 2006
We show that, for any composite system with an arbitrary number of finite-dimensional subsystems, it is possible to directly measure the multipartite concurrence of pure states by detecting only one single factorizable observable, provided that two ...

Approximation and entropy numbers of composition operators [PDF]

open access: yesConcrete Operators, 2020
Abstract We give a survey on approximation numbers of composition operators on the Hardy space, on the disk and on the polydisk, and add corresponding new results on their entropy numbers, revealing how they are different.

On the Enumeration and Asymptotic Analysis of Fibonacci Compositions [PDF]

open access: yesarXiv, 2021
We study Fibonacci compositions, which are compositions of natural numbers that only use Fibonacci numbers, in two different contexts. We first prove inequalities comparing the number of Fibonacci compositions to regular compositions where summands have a maximum possible value.

The Preparation, Characterization, and Influence of Multiple Electroless Nickel-Phosphorus (Ni-P) Composite Coatings on Poplar Veneer

open access: yesBioResources, 2015
Nickel-Phosphorus (Ni-P) composite coatings were prepared on a poplar veneer surface via a simple electroless nickel (Ni) approach. The substrate deformation, flatness, crystalline structure, and wear resistance of the Ni-P composite coatings were ...
