Uniform Hyperbolicity of a Scattering Map with Lorentzian Potential

open access: yesCondensed Matter, 2019
We show that a two-dimensional area-preserving map with Lorentzian potential is a topological horseshoe and uniformly hyperbolic in a certain parameter region.

Spatial structure-preserving and conflict-avoiding methods for point settlement selection

open access: yesOpen Geosciences, 2022
Point settlement selection is one of the critical tasks in map generalization, which should consider spatial distribution, spatial conflict, proximity to objects, and other factors.

Transport properties in nontwist area-preserving maps [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2009
Nontwist systems, common in the dynamical descriptions of fluids and plasmas, possess a shearless curve with a concomitant transport barrier that eliminates or reduces chaotic transport, even after its breakdown. In order to investigate the transport properties of nontwist systems, we analyze the barrier escape time and barrier transmissivity for the ...

A Topological Approach to Bend-Twist Maps with Applications

open access: yesInternational Journal of Differential Equations, 2011
In this paper we reconsider, in a purely topological framework, the concept of bend-twist map previously studied in the analytic setting by Tongren Ding in (2007).

Early and moderate sensory stimulation exerts a protective effect on perilesion representations of somatosensory cortex after focal ischemic damage. [PDF]

open access: yesPLoS ONE, 2014
Previous studies have shown that intensive training within an early critical time window after focal cortical ischemia increases the area of damaged tissue and is detrimental to behavioral recovery.

Dynamical trapping in the area-preserving Hénon map [PDF]

open access: yesThe European Physical Journal Special Topics, 2020
Stickiness is a well known phenomenon in which chaotic orbits expend an expressive amount of time in specific regions of the chaotic sea. This phenomenon becomes important when dealing with area-preserving open systems because, in this case, it leads to a temporary trapping of orbits in certain regions of phase space.
