Analysing nonlinear oscillation and chaos using fundamental-wave balance principle
Tongxin xuebao, 2008 The fundamental-wave current Is1 can be found by the theory of fundamental harmonic balance. Its flow direc- tion represents profit and loss of active and reactive power in order to maintain self-oscillation, when the exciting source applied to the ...

Three crossing limit cycles in planar piecewise linear systems with saddle-focus type
Electronic Journal of Qualitative Theory of Differential Equations, 2015 This paper presents an analysis on the appearance of limit cycles in planar Filippov system with two linear subsystems separated by a straight line. Under the restriction that the orbits with points in the sliding and escaping regions are not considered,

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

On the uniqueness of limit cycles in discontinuous Liénard-type systems
Electronic Journal of Qualitative Theory of Differential Equations, 2015 In this paper, we investigate the uniqueness and stability of limit cycles for a nonlinear Liénard-type differential system with a discontinuity line. By employing a transformation technique and considering the characteristic exponent of periodic orbit ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

On limit cycles of autonomous systems
Contemporary Mathematics. Fundamental DirectionsWe consider the problem of the existence of limit cycles for autonomous systems of differential equations. We present quite elementary considerations that can be useful in discussing qualitative issues that arise in the course of ordinary differential equations.
