Convergence of chaotic attractors due to interaction based on closeness

Publication date: Available online 23 September 2019Source: Physics Letters AAuthor(s): Sayantan Nag Chowdhury, Soumen Majhi, Dibakar Ghosh, Awadhesh PrasadAbstractExploration of coherence phenomena in ensembles of interacting dynamical systems has been in the centre of research in social, physical, biological and technological systems for decades. But, in most of the studies, either completely percolated time- and space-static networks or temporal connectivities disregarding the systems' own dynamics have been dealt with. In this work, we examine the correlation between structural and dynamical evolution in networks of interacting dynamical systems. We specifically demonstrate the scenario of convergence of a set of chaotic attractors into a single attractor as a result of sufficient interaction based on the closeness of their own states. We characterize this occurrence through different measures, and map the collective states in network parameters' space. We further validate our proposition while exposing the whole scenario for different chaotic systems, namely Lorenz and Rössler oscillators.

CONCLUSIONS: The concept of soldier-centered care often emerges in discussions about optimal physical performance and medical readiness for soldiers. Although soldier-centered care and patient-centered care have similar conceptual underpinning, it is important to clarify the unique physical and medical requirements for soldiers that differentiate soldier-centered care from patient-centered care. Implementing the defining attributes of soldier-centered care in the U.S. Army primary care setting may improve the quality of care and health outcomes for soldiers. When defining performance metrics for primary care models of care...

Authors: Waller SG Abstract Three important but neglected principles of evaluation of global health engagement missions are stakeholder engagement, impact, and relative value. Implementing better M&E programs could be carried out in this fiscal year, without new appropriations or manpower. The result would be cost savings and improved security cooperation.

The purpose of this study was to evaluate the performance of a new plasma based CRC screening assay, SpecColon test, which tested methylated SFRP2 and SDC2 simultaneously in a single qPCR reaction, in detecting CRC and advan...

Authors: Ieda N, Assadullah, Minabe S, Ikegami K, Watanabe Y, Sugimoto Y, Sugimoto A, Kawai N, Ishii H, Inoue N, Uenoyama Y, Tsukamura H Abstract Accumulating evidence suggests that kisspeptin neurons in the arcuate nucleus (ARC), which coexpress neurokinin B and dynorphin, are involved in gonadotropin-releasing hormone (GnRH)/luteinizing hormone (LH) pulse generation, while the anteroventral periventricular nucleus (AVPV) kisspeptin neurons are responsible for GnRH/LH surge generation. The present study aims to examine whether GnRH(1-5), a GnRH metabolite, regulates LH release via kisspeptin neurons. GnRH(1-5) was...
