Advanced Theory and Simulations, EarlyView.Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude

Questions concerning differential-algebraic operators: Toward a reliable direct numerical treatment of differential-algebraic equations [PDF]
arXiv, 2019 The nature of so-called differential-algebraic operators and their approximations is constitutive for the direct treatment of higher-index differential-algebraic equations. We treat first-order differential-algebraic operators in detail and contribute to justify the overdetermined polynomial collocation applied to higher-index differential-algebraic ...

Permutable entire functions satisfying algebraic differential equations
, 2005 It is shown that if two transcendental entire functions permute, and if one of them satisfies an algebraic differential equation, then so does the other one.Comment: 5 ...

Acoustic Rayleigh Wave Turbulence in Soft Viscoelastic Matter
Advanced Science, EarlyView.Discrete acoustic Rayleigh wave turbulence (DARWT) is observed on the free surface of viscoelastic materials under monochromatic excitation. Governed by bulk shear rigidity supporting inertial modes against surface tension, the nonlinear Rayleigh waves exhibit distinct power‐law scaling and turbulence features in their Kolmogorov–Zakharov spectra. This

Advances in Difference Equations, 2017 We apply the Chebyshev polynomial-based differential quadrature method to the solution of a fractional-order Riccati differential equation. The fractional derivative is described in the Caputo sense.

On Optical Solitons of the Fractional (3+1)-Dimensional NLSE With Conformable Derivatives
Frontiers in Physics, 2020 In this article, the fractional (3+1)-dimensional nonlinear Shrödinger equation is analyzed with kerr law nonlinearity. The extended direct algebraic method (EDAM) is applied to obtain the optical solitons of this equation with the aid of the conformable

Advanced Electronic Materials, EarlyView.Analytical calculations performed for the field‐effect transistor (FET) heterostructure “van der Waals ferrielectric film—2D semiconductor—dielectric layer” reveal the pronounced size effect of the ferrielectric negative capacitance (NC) and the subthreshold swing becomes much less than the Boltzmann's limit.

An ordinary integro-differential equation with a degenerate kernel and an integral condition
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2016 We consider the questions of one value solvability of the nonlocal boundary value problem for a nonlinear ordinary integro-differential equation with a degenerate kernel and a reflective argument.
