Synchronization investigation of the network group constituted by the nearest neighbor networks under inner and outer synchronous couplings

Abstract

A new synchronization technique of inner and outer couplings is proposed in this work to investigate the synchronization of network group. Some Haken-Lorenz lasers with chaos behaviors are taken as the nodes to construct a few nearest neighbor complex networks and those sub-networks are also connected to form a network group. The effective node controllers are designed based on Lyapunov function and the complete synchronization among the sub-networks is realized perfectly under inner and outer couplings. The work is of potential applications in the cooperation output of lasers and the communication network.

Development and preliminary testing of a questionnaire to measure mobile health information‐seeking behaviour in people with cancer

“…Previous studies have mainly focused on online health information behaviour among healthy and young populations (Chen et al, 2017;Ghiasi, 2021;Li et al, 2020;Qian et al, 2019), and some instruments have been developed to evaluate health informationseeking behaviour among these groups of people, such as the Information-seeking Behaviour Scale and Information-seeking Behaviour Scale for Undergraduates (Chen et al, 2021;Timmers & Glas, 2010). However, people with cancer are different from healthy people and young people in terms of having worse physical conditions, older age distribution and higher demand for health and disease information.…”
