On the relations between some well-known methods and the projective Riccati equations

Open Physics, 2020
Solving nonlinear evolution equations is an important issue in the mathematical and physical sciences. Therefore, traditional methods, such as the method of characteristics, are used to solve nonlinear partial differential equations. A general method for

Dynamical Analysis of Wave Solutions for the Complex Ginzburg−Landau and (4 + 1)‐Dimensional Fokas Equations With Beta Derivative

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This study propounds a detailed report on the exact wave solutions of the complex fractional Ginzburg−Landau equation (CFGLE) with quadratic‐cubic law nonlinearity and (4 + 1)‐dimensional fractional Fokas equation (FFE). For this purpose, the aforementioned equations are transformed into nonlinear ordinary differential equations (NLODEs) within the ...

Pseudoconformal Thermal Metamaterials Enabled by Thickness Engineering in a Single Material

Small Structures, Volume 6, Issue 12, December 2025.
This work presents a geometric approach for thermal manipulation using confocally elliptical core–shell structures. Isotropic medium parameters for regulating the magnitude of the temperature gradient are obtained through pseudoconformal mapping and then approximated in sample fabrication via single‐material thickness engineering, avoiding the need for

Low‐Loss Far‐Infrared Surface Phonon Polaritons in Suspended SrTiO3 Nanomembranes

Advanced Functional Materials, Volume 35, Issue 43, October 22, 2025.
The low‐loss, highly confined, and thickness‐tunable surface phonon polaritons are demonstrated in the far‐infrared regime within transferable freestanding SrTiO3 membranes, achieving high figures of merit comparable to the previous record values from the vdW materials.

On the Density–Density Correlations of the Non‐Interacting Finite Temperature Electron Gas

Contributions to Plasma Physics, Volume 65, Issue 8-9, October 2025.
ABSTRACT The density–density correlations of the non‐interacting finite temperature electron gas are discussed in detail. Starting from the ideal linear density response function and utilizing general relations from linear response theory, known and novel expressions are derived for the pair correlation function, static structure factor, dynamic ...

Solving and classifying the solutions of the Yang-Baxter equation through a differential approach. Two-state systems

, 2018
The formal derivatives of the Yang-Baxter equation with respect to its spectral parameters, evaluated at some fixed point of these parameters, provide us with two systems of differential equations. The derivatives of the $R$ matrix elements, however, can

A vertical‐slice frontogenesis test case for compressible non‐hydrostatic dynamical cores of atmospheric models

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 772, October 2025 Part A.
Our article presents a new vertical‐slice test case for benchmarking atmospheric dynamical cores. The test case is based on the Eady frontogenesis problem, producing sharp fronts that provide a challenge for numerical models. This was not previously possible in a 2D vertical‐slice configuration unless the model is incompressible, so our test case ...

An Adhesive Bonded Single Lap Joint Model

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 10, Page 4319-4338, October 2025.
ABSTRACT This paper investigates the mechanical behavior of lap joints by modeling adhesive damage and fracture using the cohesive crack technique. To improve predictive accuracy, the study adopts a linear softening law for the adhesive shear traction‐separation response and neglects peeling effects. The main goal is to derive closed‐form solutions for
