An exciting Approach to Theoretical Spectroscopy

Advanced Science, Volume 13, Issue 47, 24 August 2026.
ABSTRACT Theoretical spectroscopy, and more generally, electronic‐structure theory, are powerful concepts for describing the complex many‐body interactions in materials. They cover methods from ground‐state properties to lattice excitations and light‐matter interaction, including time‐resolved variants.

Simulation of fractionally damped mechanical systems by means of a Newmark-diffusive scheme [PDF]

, 2010
A Newmark-diffusive scheme is presented for the time-domain solution of dynamic systems containing fractional derivatives. This scheme combines a classical Newmark time-integration method used to solve second-order mechanical systems (obtained for ...

Surface Energy Modulated Self‐Assembly of Percolative Gallium Nanodroplet Films for Stretchable Electronics

Advanced Electronic Materials, Volume 12, Issue 16, 24 August 2026.
Surface‐energy guided self‐assembly of liquid metals enables the transformation of liquid metal micro/nanodroplets into continuous perocolative films on elastomeric substrates. By tailoring interfacial energetics and wetting behavior, uniform, conductive, and stretchable films are achieved, offering scalable pathways for high‐performance soft ...

Analytical Investigation of the Heat Transfer Effects of Non-Newtonian Hybrid Nanofluid in MHD Flow Past an Upright Plate Using the Caputo Fractional Order Derivative

Symmetry, 2023
The objective of this paper is to examine the augmentation of the heat transfer rate utilizing graphene (Gr) and multi-walled carbon nanotubes (MWCNTs) as nanoparticles, and water as a host fluid in magnetohydrodynamics (MHD) flow through an upright ...

Pore‐Scale Flow Dynamics Control Capillary Pressure‐Saturation‐Interfacial Area Relations in Multiphase Porous Media

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Capillary pressure–saturation relationships are central to modeling multiphase flow in porous media, yet conventional formulations often neglect how pore‐scale flow organization and interfacial geometry evolve during displacement. Here, we investigate curvature‐derived capillary pressure during immiscible two‐phase displacement using ...

A Fractional Order Controller Design Based on Bode’s Ideal Transfer Function and Bode’s Ideal Cut-Off Ideas

, 2020
In order to improve the anti-load disturbance performance of a class of motion control systems, an improved fractional order controller design based on the Bode’s ideal transfer function (BITF) is proposed in this paper. By adding a proportional-integral

Mizohata–Takeuchi inequalities for orthonormal systems

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract We establish some weighted L2$L^2$ inequalities for Fourier extension operators in the setting of orthonormal systems. In the process, we develop a direct approach to such inequalities based on generalized Wigner distributions, complementing the Schatten space approach that is prevalent in the wider context of estimates for such orthonormal ...

Variable Parameter, Fractional Order, Discrete, Inertial Transfer Function Models

International Journal of Applied Mathematics and Computer Sciences
In the paper, new, fractional order, variable parameter discrete transfer function models of an elementary inertial plant are proposed. One uses a time variable quasi time constant while the other employs, a variable time quasi constant and variable ...

Fourier Expansion‐Based Approach to the Parameter Space of Classical Systems

Annalen der Physik, Volume 538, Issue 7, July 2026.
ABSTRACT We propose a new approach to compute the classical metric tensor (CMT) and the Hannay curvature using Fourier series expansions in action‐angle variables. This approach circumvents the need for complex time‐domain integrals or the construction of generating functions, replacing them with algebraic combinations of Fourier coefficients. We prove
