A New Control Method of VSC to Supporting Instantaneous Voltage at PCC Point
In recent years, the engineering practice shows that the VSC has obvious drawbacks when it is connected to weak grid. It is easy to cause insufficient voltage support at PCC point of power systems. In order to...

Identifying bifurcations underlying a neuronal bursting of mixed-mode oscillations with two slow variables in inner hair cell
Neuronal bursting patterns are nonlinear behaviors related to various brain functions and diseases. Bursting modulated by two slow variables manifest more complex dynamics than that with one slow variable, due...

Nonlinear mechanisms for opposite responses of bursting activities induced by inhibitory autapse with fast and slow time scale
Fast and slow inhibitory synapses, respectively, induce anti- and in-phase synchronizations, showing different roles of synapse with different time scales. In the present paper, the opposite roles of inhibitor...

Fast–slow variable dissection with two slow variables related to calcium concentrations: a case study to bursting in a neural pacemaker model
Neuronal bursting is an electrophysiological behavior participating in physiological or pathological functions and a complex nonlinear behavior alternating between burst and quiescent state modulated by slow v...

The nonlinear mechanism for the same responses of neuronal bursting to opposite self-feedback modulations of autapse
In the traditional viewpoint, inhibitory and excitatory effects always induce opposite responses. In the present study, the enhanced bursting activities induced by excitatory autapses, which are consistent wit...

Dynamics of subthreshold and suprathreshold resonance modulated by hyperpolarization-activated cation current in a bursting neuron
Resonance of both subthreshold and suprathreshold membrane potentials has been found in brain or motor neurons involving in the information processing or locomotion control via frequency response, which is mai...

Paradoxical reduction and the bifurcations of neuronal bursting activity modulated by positive self-feedback
Paradoxical enhancement rather than reduction in firing activity induced by inhibitory effect is very important for both nonlinear dynamics and neuroscience. In the present paper, to build a more comprehensive...

Article
Multiple coherence resonances evoked from bursting and the underlying bifurcation mechanism
Coherence resonance (CR), which is typical nonlinear phenomenon that noise plays construct roles, has been widely investigated in single neurons at resting state instead of bursting behavior when noise free. I...

Semantic Knowledge Sharing Mechanism Based on Blockchain
In the context of big data, the construction and query of existing knowledge graph are realized by gathering scattered knowledge into a centralized big data platform. However, with the advent of the era of kno...

Different dynamics of repetitive neural spiking induced by inhibitory and excitatory autapses near subcritical Hopf bifurcation
Based on the post-inhibitory rebound (PIR) spike induced by inhibitory current pulse, in the present paper, a novel counterintuitive phenomenon that the inhibitory autapse with time delay can induce the restin...

Bifurcations of enhanced neuronal bursting activities induced by the negative current mediated by inhibitory autapse
In contrast to the traditional viewpoint that inhibitory effect can often induce the reduction of neural firing activities, negative self-feedback current mediated by inhibitory autapse is identified to enhanc...

Stochastic dynamics of conduction failure of action potential along nerve fiber with Hopf bifurcation
Action potentials can be induced by external electronic impulsive stimulations applied at one end of the unmyelinated fibers (C-fibers), while some action potentials fail to conduct to the other end of the fib...

Spatiotemporal dynamics in a network composed of neurons with different excitabilities and excitatory coupling
Spiral waves have been observed in the biological experiments on rat cortex perfused with drugs which can block inhibitory synapse and switch neuron excitability from type II to type I. To simulate the spiral ...
