Chirality-Driven Collective Dynamics in Oscillators with Attractive and Repulsive Couplings

Background Introduction Complex systems are ubiquitous in nature, appearing in various forms such as neural networks, social networks, and power grids. Understanding the dynamical transitions within these systems is often achieved through mathematical models, particularly coupled nonlinear oscillators, which exhibit a wide variety of collective beh...

Impact of Amplitude and Phase of fMRI Time Series for Functional Connectivity Analysis

The Impact of Amplitude and Phase-based MRI Time Series on Functional Connectivity Analysis Introduction Over the past decade, functional magnetic resonance imaging (fMRI) has emerged as a non-invasive imaging technique that uses blood oxygen level-dependent (BOLD) contrast to measure brain activity and study brain function (Kwong, 1996). By analyz...
