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.

A neural mass model of cross frequency coupling. [PDF]
PLoS ONE, 2017 Electrophysiological signals of cortical activity show a range of possible frequency and amplitude modulations, both within and across regions, collectively known as cross-frequency coupling.

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).

Cross-frequency coupling between gamma oscillations and deep brain stimulation frequency in Parkinson's disease. [PDF]
Brain, 2020 The disruption of pathologically enhanced beta oscillations is considered one of the key mechanisms mediating the clinical effects of deep brain stimulation on motor symptoms in Parkinson's disease.

Study of the Steady-State Operation of a Dual-Longitudinal-Mode and Self-Biasing Laser Gyroscope
Sensors, 2022 In order to stabilize the self-biasing state of a laser gyroscope, a dual-longitudinal-mode asymmetric frequency stabilization technique was studied. The special frequency stabilization is based on the accurate control of the intensity tuning curve in ...

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 ...

Harmonic Model of Static Var Generator and Analysis of Its Resonance Influence
Zhongguo dianli, 2022 Static var generators (SVGs) are widely used in photovoltaic (PV) stations because of their fast response speed and wide regulation range, which can meet such needs of the system as dynamic reactive power compensation.
