A two-frequency-two-coupling model of coupled oscillators [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2021 We considered the phase coherence dynamics in a Two-Frequency and Two-Coupling (TFTC) model of coupled oscillators, where coupling strength and natural oscillator frequencies for individual oscillators may assume one of two values (positive/negative).

Method for Adjusting Torsional Natural Frequencies of Powertrains with Novel Coupling Design
Machines, 2022 Torsional vibrations are inherently present in every rotating powertrain. In resonant conditions, torsional vibrations can be significantly amplified. A typical method to reduce the torsional vibration particularly at resonance is to modify the torsional

Neural Cross-Frequency Coupling Functions [PDF]
Frontiers in Systems Neuroscience, 2017 Although neural interactions are usually characterized only by their coupling strength and directionality, there is often a need to go beyond this by establishing the functional mechanisms of the interaction. We introduce the use of dynamical Bayesian inference for estimation of the coupling functions of neural oscillations in the presence of noise. By

Shifted coupling of EEG driving frequencies and fMRI resting state networks in schizophrenia spectrum disorders. [PDF]
PLoS ONE, 2013 INTRODUCTION: The cerebral resting state in schizophrenia is altered, as has been demonstrated separately by electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) resting state networks (RSNs).

Synthesis of Cross-Coupled Filters With Frequency-Dependent Couplings [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2017 This paper presents a novel synthesis technique for coupled-resonator filters with frequency-dependent couplings. Unlike the works so far appeared in the literature, the proposed technique is not based on the optimization of a network with assigned topology, but it consists in the explicit synthesis of a folded prototype with frequency-dependent ...

A Multiplex Connectivity Map of Valence-Arousal Emotional Model
IEEE Access, 2020 A high number of studies have already demonstrated an electroencephalography (EEG)-based emotion recognition system with moderate results. Emotions are classified into discrete and dimensional models.

Untangling cross-frequency coupling in neuroscience [PDF]
Current Opinion in Neurobiology, 2014 AbstractCross-frequency coupling (CFC) has been proposed to coordinate neural dynamics across spatial and temporal scales. Despite its potential relevance for understanding healthy and pathological brain function, the standard CFC analysis and physiological interpretation come with fundamental problems.

Perturbative and nonperturbative quasinormal modes of 4D Einstein–Gauss–Bonnet black holes
European Physical Journal C: Particles and Fields, 2020 We study the propagation of probe scalar fields in the background of 4D Einstein–Gauss–Bonnet black holes with anti-de Sitter (AdS) asymptotics and calculate the quasinormal modes.

Cross-Frequency Coupling and Intelligent Neuromodulation
Cyborg and Bionic Systems, 2023 Cross-frequency coupling (CFC) reflects (nonlinear) interactions between signals of different frequencies. Evidence from both patient and healthy participant studies suggests that CFC plays an essential role in neuronal computation, interregional interaction, and disease pathophysiology.

Mode coupling internal resonance characteristics of submerged floating tunnel tether
SN Applied Sciences, 2021 Article Highlights When the tether is only subjected to in-plane or out of plane harmonic loads, if the first-order in-plane and out of plane frequencies of tether are close to each other, the tether is prone to occur modal coupling internal resonance ...
