Dynamical properties of a meminductor chaotic system with fractal–fractional power law operator Chaos Solitons Fractals (IF 7.8) Pub Date : 2023-09-18 Peiluan Li, Liqin Han, Changjin Xu, Xueqing Peng, Mati ur Rahman, Sairu Shi
Purpose: This study aims to explore the intricate and concealed chaotic structures of meminductor systems and their applications in applied sciences by utilizing fractal fractional operators (FFOs). Methods: The dynamical analysis of a three-dimensional meminductor system with FFO in the Caputo sense is presented, and a unique solution for the system is obtained via a novel contraction in an orbitally

The global dynamics of a new fractional-order chaotic system Chaos Solitons Fractals (IF 7.8) Pub Date : 2023-09-18 Ping Liu, Yulan Zhang, Khidhair Jasim Mohammed, António M. Lopes, Hassan Saberi-Nik
This paper investigates the global dynamics of a new 3-dimensional fractional-order (FO) system that presents just cross-product nonlinearities. Firstly, the FO forced Lorenz-84 system is introduced and the stability of its equilibrium points, as well as the chaos control for their stabilization, are addressed. Secondly, dynamical behavior is further analyzed and bifurcation diagrams, phase portraits

A study on Zika–Dengue coinfection model with microcephaly newborn dynamics Chaos Solitons Fractals (IF 7.8) Pub Date : 2023-09-14 Mona Zevika, Rudy Kusdiantara, Nuning Nuraini, Edy Soewono
A study of data on the Zika outbreak in Brazil in 2015–2016 provides knowledge that Zika infection can trigger brain disorders such as Guillain–Barré Syndrome in adults and microcephaly in newborns. Zika infection is a vector-borne disease most commonly transmitted to humans through an infected Aedes mosquito bite, which is also the primary vector for dengue. Thus, many cases of these two diseases
