Altered brain white matter structural motor network in spinocerebellar ataxia type 3

open access: yesAnnals of Clinical and Translational Neurology, 2023
Objectives Spinocerebellar ataxia type 3 is a disorder within the brain network. However, the relationship between the brain network and disease severity is still unclear.

Robust transitivity and topological mixing for $C^1$-flows [PDF]

open access: yes, 2003
We prove that non-trivial homoclinic classes of $C^r$-generic flows are topologically mixing. This implies that given $\Lambda$ a non-trivial $C^1$-robustly transitive set of a vector field $X$, there is a $C^1$-perturbation $Y$ of $X$ such that the ...

Chaos-Based Image Encryption: Review, Application, and Challenges

open access: yesMathematics, 2023
Chaos has been one of the most effective cryptographic sources since it was first used in image-encryption algorithms. This paper closely examines the development process of chaos-based image-encryption algorithms from various angles, including symmetric

Rich-club connectivity dominates assortativity and transitivity of complex networks [PDF]

open access: yes, 2010
Rich-club, assortativity and clustering coefficients are frequently-used measures to estimate topological properties of complex networks. Here we find that the connectivity among a very small portion of the richest nodes can dominate the assortativity ...

Topological transitions in metals

open access: yesPhysical Review B, 2019
We investigate if a sharp topological transition in a metal with a large Fermi surface may be detected in transport measurements. In particular, we address if a skew scattering and a side jump on elastic disorder in the bulk of such a metal masks signatures of the topological transition.

Topological theory of phase transitions

open access: yesJournal of Physics A: Mathematical and Theoretical, 2022
AbstractThe investigation of the Hamiltonian dynamical counterpart of phase transitions, combined with the Riemannian geometrization of Hamiltonian dynamics, has led to a preliminary formulation of a differential-topological theory of phase transitions.

Induced Representation Method in the Theory of Electron Structure and Superconductivity

open access: yesAdvances in Mathematical Physics, 2019
It is shown that the application of theorems of induced representations method, namely, Frobenius reciprocity theorem, transitivity of induction theorem, and Mackey theorem on symmetrized squares, makes simplifying standard techniques in the theory of ...

Dynamical consequences of a free interval: minimality, transitivity, mixing and topological entropy

open access: yes, 2011
We study dynamics of continuous maps on compact metrizable spaces containing a free interval (i.e., an open subset homeomorphic to an open interval).
