We present a new Control Volume Finite Element Method (CVFEM) for the drift-diffusion equations. The method combines a conservative formulation of the current continuity equations with a novel definition of an exponentially fitted elemental current density. An edge element representation of the nodal CVFEM current density in the diffusive limit motivates this definition. We prove that in the ab...

Animal habitat selection, among other ecological phenomena, is spatially scale dependent. Habitat selection by American beavers Castor canadensis (hereafter, beaver) has been studied at singular spatial scales, but to date no research addresses multi-scale selection. Our objectives were to determine if beaver habitat selection was specialized to semiaquatic habitats and if variables explaining ...

In this research paper, we present a novel frame work for handling $m$-polar information by combining the theory of $m-$polar fuzzy  sets with graphs. We introduce certain types of edge regular $m-$polar fuzzy graphs and edge irregular $m-$polar fuzzy graphs. We describe some useful properties of edge regular, strongly edge irregular and strongly edge totally irregular $m-$polar fuzzy graphs. W...

Abstract This paper details the theory of edge shear layer collapse as density approaches Greenwald limit. It significantly extends earlier work, which was restricted in applicability. The zonal flow screening length is calculated for banana, plateau and Pfirsch–Schluter regimes. Poloidal field scaling persists regime. Neoclassical drift wave–zonal dynamics are combined a theory, then reduced t...

Atomistic simulations are performed to study the nonlinear mechanical behavior of graphene nanoribbons under quasistatic uniaxial tension, emphasizing the effects of edge structures (armchair and zigzag, without and with hydrogen passivation) on elastic modulus and fracture strength. The numerical results are analyzed within a theoretical model of thermodynamics, which enables determination of ...

Post-dispersal seed agents of mortality include pathogens, invertebrates, and vertebrates, which may shape tropical tree populations and communities. In this study I experimentally evaluated Dipteryx alata endocarp removal both in the interior and edge of Cerrado vegetation. Specifically, I simulated primary dispersion of endocarps by bats and evaluated secondary removal intensity according to ...
