Interventional therapies for chronic heart failure: An overview of recent developments
ESC Heart Failure, Volume 12, Issue 2, Page 1081-1094, April 2025.Abstract Heart failure (HF), the final manifestation of most cardiovascular diseases, has become a major global health concern, affecting millions of individuals. Despite basic drug treatments, patients present with high morbidity and mortality rates. However, recent advancements in interventional therapy have shown promising results in improving the ...

Period-doubling bifurcation to alternans in paced cardiac tissue: crossover from smooth to border-collision characteristics. [PDF]
Phys Rev Lett, 2007 We investigate, both experimentally and theoretically, the period-doubling bifurcation to alternans in heart tissue. Previously, this phenomenon has been modeled with either smooth or border-collision dynamics.

Period Doubling Bifurcation Point Detection Strategy with Nested Layer Particle Swarm Optimization
, 2017 This paper proposes a bifurcation point detection strategy based on nested layer particle swarm optimization (NLPSO). The NLPSO is performed by two particle swarm optimization (PSO) algorithms with a nesting structure.

Global Strategy Journal, EarlyView.Abstract Research Summary This article develops a conceptual framework for understanding multinational enterprise (MNE) resilience in the era of cascading crises. We define resilience as the MNE's capacity to absorb disruption, maintain or restore functioning, and reconfigure operations as conditions shift.

Inverse period-doubling bifurcation in an atmospheric helium dielectric barrier discharge
, 2014 Period-doubling bifurcation has been frequently observed in the numerical simulations of atmospheric dielectric barrier discharges and it also has been partly confirmed in our previous experiments.

Study of Period-doubling Bifurcations of a Vibro-impact System
工程科学与技术, 2006 :In order to study the relation of the period-doubling bifurcation and the Hopf bifurcation,the period-doubling bifurcation problems of a vibro-impact system is investigated when the periodical solutions lose its stability.

Electronic implementation of a repressilator with quorum sensing feedback.
PLoS ONE, 2013 We investigate the dynamics of a synthetic genetic repressilator with quorum sensing feedback. In a basic genetic ring oscillator network in which three genes inhibit each other in unidirectional manner, an additional quorum sensing feedback loop ...
