Global dynamics of a planar Filippov system with a regular-SN
四川大学学报. 自然科学版, 2022 In this paper, we investigate the global dynamics of a planar Filippov system with a regular-SN for general parameters not required to be sufficiently small.

Complexity, 2021 Tuberculosis (TB) is a serious global health threat that is caused by the bacterium Mycobacterium tuberculosis, is extremely infectious, and has a high mortality rate. In this paper, we developed a model of TB infection to predict the impact of saturated

Advanced Optical Materials, EarlyView.A proline‐integrated donor–acceptor fluorophore enables multifunctional luminescence through rational molecular design. Water‐vapor‐responsive mechanochromic luminescence (MCL) with circularly polarized luminescence (CPL) switching and efficient visualization of latent fingerprints (LFPs) are realized from this single small organic molecule.

Homoclinic Points Calculation Method With Particle Swarm Optimization
IEEE AccessThis paper proposes a novel algorithm to accurately calculate the coordinates of homoclinic points observed in discrete-time dynamical systems. The proposed method is based on the particle swarm optimization method. Compared with the current methods, the

DELAY-INDUCED MULTISTABILITY NEAR A GLOBAL BIFURCATION [PDF]
International Journal of Bifurcation and Chaos, 2008 We study the effect of a time-delayed feedback within a generic model for a saddle-node bifurcation on a limit cycle. Without delay the only attractor below this global bifurcation is a stable node. Delay renders the phase space infinite-dimensional and creates multistability of periodic orbits and the fixed point.

Advanced Robotics Research, EarlyView.This study explores how information processing is distributed between brains and bodies through a codesign approach. Using the “backpropagation through soft body” framework, brain–body coupling agents are developed and analyzed across several tasks in which output is generated through the agents’ physical dynamics.

Global Bifurcation in a General Leslie Type Predator–Prey System with Prey Taxis
AxiomsIn this paper, the local and global structure of positive solutions for a general predator–prey model in a multi-dimension with ratio-dependent predator influence and prey taxis is investigated.
