Double symbolic joint entropy in nonlinear dynamic complexity analysis
, 2017 Symbolizations, the base of symbolic dynamic analysis, are classified as global static and local dynamic approaches which are combined by joint entropy in our works for nonlinear dynamic complexity analysis.

Inverse Optimal Attitude Stabilization of Flexible Spacecraft with Actuator Saturation
International Journal of Aerospace Engineering, 2016 This paper presents a new robust inverse optimal control strategy for flexible spacecraft attitude maneuvers in the presence of external disturbances and actuator constraint. A new constrained attitude controller for flexible spacecraft is designed based

Estimation of Power System Inertia Using Nonlinear Koopman Modes
, 2018 We report a new approach to estimating power system inertia directly from time-series data on power system dynamics. The approach is based on the so-called Koopman Mode Decomposition (KMD) of such dynamic data, which is a nonlinear generalization of ...

Quantum Difference Langevin System with Nonlocal q-Derivative Conditions
International Journal of Mathematics and Mathematical Sciences, 2016 We introduce a new class of boundary value problems for Langevin quantum difference systems. Some new existence and uniqueness results for coupled systems are obtained by using fixed point theorems.

Nonlinear Dynamic Analysis of Rotor‐Bearing System with Cubic Nonlinearity
Shock and Vibration, 2021 Nonlinear dynamic characteristics of a rotor‐bearing system with cubic nonlinearity are investigated. The comprehensive effects of the unbalanced excitation, the internal clearance, the nonlinear Hertzian contact force, the varying compliance vibration, and the nonlinear stiffness of support material are considered.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
