The paper concerns the dynamics and stability of double-walled carbon nanotubes conveying fluid. The equations of motion adopted in the current study to describe the dynamics of such nano-pipes stem from the classical Bernoulli–Euler beam theory. S

This paper discusses the analysis and computations of chaos–hyperchaos (or vice versa) transition in Rössler–Nikolov–Clodong O (RNC-O) hyperchaotic system. Our work is motivated by our previous analysis of hyperchaotic transitional regimes of

This article presents a comparative study of Kiepert’s trefoil and its related curves, combining a variety of tools from differential and algebraic geometry, integrable systems, elastica theory, and special functions. While this curve was classical

In this paper, the non-linear dynamical behavior of a 3D autonomous dissipative system of Hopf–Langford type is investigated. Through the help of a mode transformation (as the system’s energy is included) it is shown that the 3D nonlinear system

In this paper, the dynamics of a 3D autonomous dissipative nonlinear system of ODEs-Rössler prototype-4 system, was investigated. Using Lyapunov-Andronov theory, we obtain a new analytical formula for the first Lyapunov’s (focal) value at the boun

Angiotensin II (ANG II) is a principal secretagogue of adrenal zona glomerulosa (ZG) cells. The transduction process includes a depolarization of the plasma membrane and the activation of calcium influx. The ANG II-induced depolarization is associate

The cardiac L-type calcium current (I(Ca,L)) is an important regulator of myocardial contractility. It is activated by sympathetic stimulation and inhibited by parasympathetic activity via muscarinic acetylcholine receptors. Muscarinic inhibition of

An extracellular calcium (Ca2+o)-sensing receptor (CaR) plays crucial roles in maintaining systemic calcium homeostasis. The CaR is also expressed in other cells uninvolved in systemic mineral ion homeostasis, including keratinocytes, fibroblasts, an

A G protein-coupled, extracellular calcium (Ca(0)2+)-sensing receptor (CaR) cloned from parathyroid, kidney, and brain plays crucial roles in systemic calcium metabolism. In brain, the CaR is located in nerve terminals as well as in fiber tracts, whe
