We present a nonequilibrium statistical mechanics description of rank abundance relations (RAR) in random community models of ecology. Specifically, we study a multispecies replicator system with quenched random interaction matrices. We here consider symmetric interactions as well as asymmetric and antisymmetric cases. RARs are obtained analytically via a(More)
Electrical characteristics were controlled in the 1.8-GHz range film bulk acoustic wave (BAW) resonator by a layer arrangement consisting of ZnO, Al2O3 and SiO2 thin films. BAW resonators with ZnO / Al2O3 / SiO2 and ZnO / SiO2 / Al2O3 structure were designed on secondary harmonics around 1.8GHz using finite element method (FEM). Comparing the ZnO / SiO2 /(More)
ductance of layer. These dependencies showed that hybridization appears when sheet conductance of layer (σ) exceeds some critical value σcr), the magnitude of which changes in wide range and depends on material and plate orientation. For example, for aforementioned hybrid pair A0 SH0 in potassium niobate σcr = 10−3S. If σ < σcr modes are not coupled, i.e.(More)
