Circuit Implementation and Antisynchronization of an Improved Lorenz Chaotic System

Shock and Vibration, 2016
An improved Lorenz chaotic system is proposed, making it into a circuit which is easy to be implemented by using some basic electronic components. The antisynchronization error systems can be asymptotically stabilized at the origin with three different ...

On Lorenz-type attractors in a six-dimensional generalization of the Lorenz model [PDF]

Известия высших учебных заведений: Прикладная нелинейная динамика
The topic of the paper — Lorenz-type attractors in multidimensional systems. We consider a six-dimensional model that describes convection in a layer of liquid, taking into account impurities in the atmosphere and liquid, as well as the rotation of

Stabilized Cubic GeTe With Matched Grain‐Boundary Networks and Band Convergence for High‐Performance Dual‐Mode Thermoelectric Devices

Advanced Science, EarlyView.
I‐doping stabilizes the cubic phase of GeTe and generates “electron‐transparent, phonon‐blocking” grain boundary networks while inducing valence‐band convergence. This synergistic structural‐electronic design enables effective electron‐phonon decoupling, achieving an exceptional average zTave of ∼1.62, a peak zT of ∼2.2, and enhanced mechanical ...

Hyperchaotic Lorenz system

Acta Physica Sinica, 2007
This paper presents a four-dimensional hyperchaotic Lorenz system, obtained by adding a nonlinear controller to Lorenz chaotic system. The hyperchaotic Lorenz system is studied by bifurcation diagram, Lyapunov exponent spectrum and phase diagram. Numerical simulations show that the new system's behavior can be convergent, divergent, periodic, chaotic ...

Reorganization of Innate Immune Cell Lipid Profiles by Bioinspired Meroterpenoids to Limit Inflammation

Advanced Science, EarlyView.
Resolution pharmacology is an emerging strategy to tackle inflammatory pathologies. Bioinspired meroterpenoids induce a lipid mediator class switch toward inflammation resolution in vitro and in vivo by targeting key nodes in lipid mediator biosynthesis and neutral lipid dynamics.

Generalized Lorenz-Type Systems

Journal of Mathematical Analysis and Applications, 1996
The author studies generalization of the Lorenz system of the form \(x'=a(y-x)\), \(y'=f(x)- ny-xz\), \(z'=xy-bz\). He first shows that for the classical choice \(f(x)=rx\) and some special choices of parameters and initial values the exact solutions of the Lorenz system may be obtained in terms of Jacobian elliptic functions.

Integration of Redox‐Active Polyoxovanadate Clusters into PMMA: Structure, Nanoscale Organization and Multilevel Redox Switching

Advanced Electronic Materials, EarlyView.
Solvent‐processable polyoxovanadate–PMMA nanocomposites exhibit concentration‐dependent 2D and 3D organization on gold surfaces, while retaining multilevel redox switching at room temperature. These hybrids bridge nanoscale functionality and macroscopic measurement, establishing a versatile platform for hybrid molecular–polymer memory materials ...

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices

Advanced Electronic Materials, EarlyView.
Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...
