Some Novel Cosine Similarity Measures Based on Complex Hesitant Fuzzy Sets and Their Applications
Journal of Mathematics, 2021 The theory of complex hesitant fuzzy set (CHFS) is a modification technique of the complex fuzzy set (CFS) to cope with awkward and unreliable information’s in daily life issues.

Point-Symmetric Extension-Based Interval Shannon-Cosine Spectral Method for Fractional PDEs
Discrete Dynamics in Nature and Society, 2020 The approximation accuracy of the wavelet spectral method for the fractional PDEs is sensitive to the order of the fractional derivative and the boundary condition of the PDEs.

On a subfamily of starlike functions related to hyperbolic cosine function
The Journal of Analysis, 2023 We introduce and study a new Ma-Minda subclass of starlike functions $\mathcal{S}^*_{\varrho},$ defined as $$\mathcal{S}^{*}_{\varrho}:=\left\{f\in\mathcal{A}:\frac{zf'(z)}{f(z)} \prec \cosh \sqrt{z}=:\varrho(z), z\in\mathbb{D} \right\},$$ associated with an analytic univalent function $\cosh \sqrt{z},$ where we choose the branch of the square root ...

ON GENERALIZED SINE AND COSINE FUNCTIONS
Demonstratio Mathematica, 1995 The author finds addition formulas for functions \(f\), \(g\) which satisfy the functional equation \((f (x))^n+ (g (x))^n =1\), where \(f\), \(g\) are supposed to be real functions on a given group \((X, +)\) and \(n\in \mathbb{N}\) is fixed. The obtained addition formulas coincide with the well known representations of \(\cos (x+y)\) and \(\sin (x+y)\

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

On the Superstability Related with the Trigonometric Functional Equation
Advances in Difference Equations, 2009 We will investigate the superstability of the (hyperbolic) trigonometric functional equation from the following functional equations: f(x+y)±g(x−y)=λf(x)g(y), f(x+y)±g(x−y)=λg(x)f(y), f(x+y)±g(x−y)=&

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

Adaptive channel estimation for cognitive fully adaptive radar
IET Radar, Sonar & Navigation, 2022 The paper addresses channel state information estimation for a cognitive radar system. The underlying radar signal model considered in this paper is based on a stochastic Green's function approach. In the radar model, the clutter returns can be expressed

Optical vortices with an infinite number of screw dislocations
Компьютерная оптика, 2021 In optical data transmission with using vortex laser beams, data can be encoded by the topological charge, which is theoretically unlimited. However, the topological charge of a single separate vortex (screw dislocation) is limited by possibilities of ...

T1 Over Squared Proton Density Ratio to Characterize Multiple Sclerosis Lesions
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Differentiating remyelinated from demyelinated lesions in MS remains challenging without histological confirmation. This study introduces the T1‐to‐PD2 ratio (TPR) imaging approach and evaluates its ability to characterize MS lesions alongside other quantitative MRI (qMRI) metrics. Methods Thirty individuals with MS (mean age: 47.5 ±
