Wide-bandgap gallium oxide (Ga2O3) is one of the most promising semiconductor materials for solar-blind (200 nm–280 nm) photodetection. In its amorphous form, a-Ga2O3 maintains its intrinsic optoelectronic properties while can be prepared at a low growth temperature, thus is compatible with Si integ ...

We study the following Kirchhoff equation ▫$$ - \left( 1 + b \int_{\mathbb{R}^3} |\nabla u|^2 dx \right) \Delta u + V(x) u = f(x,u), \quad x \in \mathbb{R}^3. $$▫ A feature of this paper is that the nonlinearity ▫$f$▫ and the potential ▫$V$▫ are indefinite, hence sign-changing. Under some appropriat ...

To study the method of reducing the low-frequency vibration noise of tires, a passenger car tire (205/55R16) is taken as the research object. The dynamic grounding characteristics and vibration reduction mechanism of the cat’s paw pad are analysed. The research showed that the swing deformation char ...

Obravnavamo naslednji nelinearni problem Kirchhoffovega tipa ▫$$\begin{cases} - \Big (a+b \int_{\mathbb{R}^3} |\nabla u|^2 \Big) \Delta u + V(x)u = f(u), & \text{in} \quad\mathbb{R}^3 \; , \\ u \in H^1 (\mathbb{R}^3) \; , \end{cases}$$▫ kjer sta ▫$a,b > 0$▫ konstanti, nelinearni člen ▫$f$▫ je superl ...
