Planar Bistable Structures Detection via the Conley Index and Applications to Biological Systems

Mathematics, 2023
Bistability is a ubiquitous phenomenon in life sciences. In this paper, two kinds of bistable structures in two-dimensional dynamical systems are studied: one is two one-point attractors, another is a one-point attractor accompanied by a cycle attractor.

Quasi-separatrix layers induced by ballooning instability in the near-Earth magnetotail [PDF]

Annales Geophysicae, 2019
Magnetic reconnection processes in the near-Earth magnetotail can be highly three-dimensional (3-D) in geometry and dynamics, even though the magnetotail configuration itself is nearly two-dimensional due to the symmetry in the dusk–dawn direction.

Parameter dependencies of the separatrix density in low triangularity L-mode and H-mode JET-ILW plasmas

Nuclear Fusion, 2023
The midplane electron separatrix density, n _e,sep , in JET-ILW L-mode and H-mode low triangularity deuterium fuelled plasmas exhibits a strong explicit dependence on the averaged outer divertor target electron temperature, n _e,sep ∼ T _e,ot ^−1/2 ...

Manipulation of breather waves with split-dispersion cascaded fibers

New Journal of Physics, 2022
A stabilization scheme is proposed for the dynamics of breather waves induced by the coherent-seed modulation instability based on manipulation of phase-space trajectory. Theoretical and numerical analysis show that carefully dispersion- and nonlinearity-

Limit-cycle-oscillation induced from the positive feedback amplification of radial electric field in the scrape-off-layer

Nuclear Fusion, 2023
Based on a heuristic model of the scrape-off-layer (SOL) plasma dynamics, a new type of limit-cycle-oscillation (LCO) is shown to be possible in the SOL region.

Study of the double null divertor configuration in DTT

Nuclear Materials and Energy, 2021
On the way to the development of a fusion reactor based on the Tokamak configuration, the Divertor Test Tokamak facility (DTT) [1] in construction in Italy should provide useful information for the DEMO [2] reactor in the field of the power and particle ...

Dynamics of the Transition corona [PDF]

, 2014
Magnetic reconnection between open and closed magnetic field in the corona is believed to play a crucial role in the corona/heliosphere coupling. At large scale, the exchange of open/closed connectivity is expected to occur in pseudo-streamer structures.
