The Influences of Canopy Species and Topographic Variables on Understory Species Diversity and Composition in Coniferous Forests by Hong Huo, Qi Feng, Yong-hong Su

“…Using constrained ordination and the variation partitioning model, we quantitatively assessed the relative effects of two sets of explanatory variables on understory species composition. The results showed that topographic variables had higher explanatory power than did site conditions for understory plant distributions. …”

Composition of entire function and analytic functions in the unit ball with a vanished gradient by A. I. Bandura, T. M. Salo, O. B. Skaskiv

“…The obtained results complement earlier published results with $\mathop{grad}\Phi(z)=(\frac{\partial \Phi(z)}{\partial z_1}, \ldots, \frac{\partial \Phi(z)}{\partial z_j},\ldots,\frac{\partial \Phi(z)}{\partial z_n})\ne \mathbf{0}.$ Also, we study a more general composition $H(\mathbf{w})=G(\mathbf{\Phi}(\mathbf{w}))$, where $G: \mathbb{C}^n\to \mathbb{C}$ is an entire function of the bounded $\mathbf{L}$-index in joint variables, $\mathbf{\Phi}: \mathbb{B}^m\to \mathbb{C}^n$ is a vector-valued analytic function, and $\mathbf{L}: \mathbb{C}^n\to\mathbb{R}^n_+$ is a continuous function. …”

Variable Sound Insulation Structure with MFC Elements by Paweł GÓRSKI, Michał KOZUPA

“…One of the possible opportunities to extend the field of applications of active noise reduction systems is using active structures of variable sound insulation. The paper presents an analysis of ways of reducing noise with a structure of variable sound insulation consisting of a metal plate, active elements (Macro Fiber Composite), and a control system. …”
