Evolutionary Stability of Ecological Hierarchy [PDF]

open access: yes, 2003
A self-similar hierarchical solution that is both dynamically and evolutionarily stable is found to the multi dimensional Lotka-Volterra equation with a single chain of prey-predator relations.

Cole-Hopf Like Transformation for Schr\"odinger Equations Containing Complex Nonlinearities [PDF]

open access: yes, 2002
We consider systems, which conserve the particle number and are described by Schr\"odinger equations containing complex nonlinearities. In the case of canonical systems, we study their main symmetries and conservation laws.

Small-Angle Scattering from Nanoscale Fat Fractals

open access: yesNanoscale Research Letters, 2017
Small-angle scattering (of neutrons, x-ray, or light; SAS) is considered to describe the structural characteristics of deterministic nanoscale fat fractals.

Controlling chimeras

open access: yesNew Journal of Physics, 2015
Coupled phase oscillators model a variety of dynamical phenomena in nature and technological applications. Non-local coupling gives rise to chimera states which are characterized by a distinct part of phase-synchronized oscillators while the remaining ...

A minimal model of self-consistent partial synchrony

open access: yesNew Journal of Physics, 2016
We show that self-consistent partial synchrony in globally coupled oscillatory ensembles is a general phenomenon. We analyze in detail appearance and stability properties of this state in possibly the simplest setup of a biharmonic Kuramoto–Daido phase ...

Adaptive elimination of synchronization in coupled oscillator

open access: yesNew Journal of Physics, 2017
We present here an adaptive control scheme with a feedback delay to achieve elimination of synchronization in a large population of coupled and synchronized oscillators.

Demand forecasting and information platform in tourism

open access: yesOpen Physics, 2017
Information asymmetry and the bullwhip effect have been serious problems in the tourism supply chain. Based on platform theory, this paper established a mathematical model to explore the inner mechanism of a platform’s influence on stakeholders’ ability ...

The nonlinear Dirac equation in Bose–Einstein condensates: superfluid fluctuations and emergent theories from relativistic linear stability equations

open access: yesNew Journal of Physics, 2015
We present the theoretical and mathematical foundations of stability analysis for a Bose–Einstein condensate (BEC) at Dirac points of a honeycomb optical lattice. The combination of s -wave scattering for bosons and lattice interaction places constraints
