Hyperbolic Cross Truncations for Stochastic Fourier Cosine Series
The Scientific World Journal, 2014 Based on our decomposition of stochastic processes and our asymptotic representations of Fourier cosine coefficients, we deduce an asymptotic formula of approximation errors of hyperbolic cross truncations for bivariate stochastic Fourier cosine series ...

On the M-hypercyclicity of cosine function on Banach spaces
Boletim da Sociedade Paranaense de Matemática, 2019 In this paper we introduce and study the M-hypercyclicity of strongly continuous cosine function on separable complex Banach space, and we give the criteria for cosine function to be M-hypercyclic.

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Similarity Measures of q-Rung Orthopair Fuzzy Sets Based on Cosine Function and Their Applications
Mathematics, 2019 In this article, we propose another form of ten similarity measures by considering the function of membership degree, non-membership degree, and indeterminacy membership degree between the q-ROFSs on the basis of the traditional cosine similarity ...

On the Spectrum of Cosine Functions
Journal of Mathematical Analysis and Applications, 1999 AbstractIn this paper we give characterizations of the resolvent set of the generatorAof a strongly continuous cosine functionC(t) in terms of certain solution properties of the differential equationu″(t)=Au(t)+f(t).

Bounded Cosine Functions Close to Continuous Scalar Bounded Cosine Functions [PDF]
Integral Equations and Operator Theory, 2016 Let $(C(t))\_{t \in R}$ be a cosine function in a unital Banach algebra. We show that if $sup\_{t\in R}\Vert C(t)-cos(t)\Vert \textless{} 2$ for some continuous scalar bounded cosine function $(c(t))\_{t\in \R},$ then the closed subalgebra generated by $(C(t))\_{t\in R}$ is isomorphic to $\C^k$ for some positive integer $k.$ If, further, $sup\_{t\in \R}

Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States
Advanced Functional Materials, EarlyView.The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.

Self‐organized Criticality in Neuromorphic Nanowire Networks With Tunable and Local Dynamics
Advanced Functional Materials, EarlyView.Memristive nanowire networks (NWNs) are shown to be electrically tunable to a critical state where specific local dynamics evaluated by multiterminal characterization are exploited as feature selection in nonlinear transformation (NLT) tasks.

Neutrosophic Refined Similarity Measure Based on Cosine Function [PDF]
Neutrosophic Sets and Systems, 2014 In this paper, the cosine similarity measure of neutrosophic refined (multi-) sets is proposed and its properties are studied. The concept of this cosine similarity measure of neutrosophic refined sets is the extension of improved cosine similarity ...
