Random Stability of an Additive-Quadratic-Quartic Functional Equation
Using the fixed point method, we prove the generalized Hyers-Ulam stability of the following additive-quadratic-quartic functional equation f(x+2y)+f(x−2y)=2f(x+y)+2f(−x−y)+2f(x−y)+2f(y−x)−4f(−x)−2f(

Some generalization of the quadratic and Wilson’s functional equation [PDF]
We find the solutions $${f,g,h \colon G \to X,\,\varphi \colon G \to \mathbb{K}}$$ of each of the functional equation $$\sum\limits_{\lambda \in K} f(x + \lambda y) = |K| \varphi (y) g(x) +

A simulative evaluation of triply periodic minimal surface (TPMS) structures for an elastocaloric application under compressive load is performed. For the evaluation of the structure's performance, surface/volume ratio, generated heat and invested mechanical work are taken into account and are compared to a tube as a reference specimen.

Hyers-Ulam stability of an additive-quadratic functional equation
In this paper, we introduce the following $(a,b,c)$-mixed type functional equation of the form \\$g(ax_1+bx_2+cx_3 )-g(-ax_1+bx_2+cx_3 )+g(ax_1-bx_2+cx_3 )-g(ax_1+bx_2-cx_3 ) +2a^2 [g(x_1 )+g(-x_1)]+2b^2 [g(x_2 )+g(-x_2)]+2c^2 [g(x_3 )+g(-x_3)]+a[g(x_1 )-

On a functional equation that has the quadratic-multiplicative property
In this article, we obtain the general solution and prove the Hyers-Ulam stability of the following quadratic-multiplicative functional equation: ϕ ( s t − u v ) + ϕ ( s v + t u ) = [ ϕ ( s ) + ϕ ( u ) ] [ ϕ ( t ) + ϕ ( v ) ] \phi (st-uv)+\phi (sv+tu)={[}

PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

This study demonstrates that in sputter‐deposited Tb3Fe5O12 (TbIG)/nonmagnetic metal (NM) heterostructures, the interfacial Dzyaloshinskii–Moriya Interaction (DMI) originates at the TbIG/NM interface. Furthermore, measurements suggest a significant interfacial DMI arising from a second non‐local interface, created by inserting a Cu spacer layer between
