Dynamic mitigation of the tearing mode instability in a collisionless current sheet
Scientific Reports, 2021 Dynamic mitigation for the tearing mode instability in the current sheet in collisionless plasmas is demonstrated by applying a wobbling electron current beam.

Kinetic simulations of the coupling between current instabilities and reconnection in thin current sheets [PDF]
Nonlinear Processes in Geophysics, 2000 We investigate the coupling between current and tearing instability modes of a thin current sheet using the particle code GISMO. We identify pure tearing modes (kx≠ 0), instabilities in the current flow direction (ky≠ 0) and general 3D reconnection modes

Instability and Breakup of Model Tear Films
Investigative Opthalmology & Visual Science, 2016 An experimental platform to replicate the human tear film on a contact lens is presented. The influence of interfacial viscoelasticity in stabilizing in vitro model tear films against breakup and dewetting is investigated using this instrument.Model tear films consisting of bovine meibomian lipids (meibum) spread on either PBS or artificial tear ...

Case report: Atlantoaxial instability and subluxation in a dog with Ehlers–Danlos syndrome
Frontiers in Veterinary Science, 2023 Ehlers–Danlos syndrome is a rare, heritable connective tissue disorder characterized by soft, hyperextensible skin, joint hypermobility, and tissue fragility, the severity of which can range from mild to severe.

3D reconnection due to oblique modes: a simulation of Harris current sheets [PDF]
Nonlinear Processes in Geophysics, 2000 Simulations in three dimensions of a Harris current sheet with mass ratio, mi/me = 180, and current sheet thickness, pi/L = 0.5, suggest the existence of a linearly unstable oblique mode, which is independent from either the drift-kink or the tearing ...

Distinctive features of internally driven magnetotail reconnection
Geophysical Research Letters, 2017 Onset of reconnection in a tail‐like equilibrium with a finite Bz magnetic field component is studied using 3‐D explicit particle‐in‐cell simulations. Due to a region of a tailward Bz gradient the onset develops spontaneously as the magnetic flux release

Nuclear Fusion, 2022 Recent MHD simulations find that the reversal of the local resistive interchange parameter $D_\mathrm{R}$ from negative to positive due to impurity radiation cooling is able to linearly destabilize the resistive tearing mode (TM) growth in a tokamak ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Tearing instability, Kelvin‐Helmholtz instability, and magnetic reconnection [PDF]
Journal of Geophysical Research: Space Physics, 1997 Two closely related macroscopic instabilities at the magnetospheric boundary layer are the tearing instability and the Kelvin‐Helmholtz (KH) instability. It has been suggested that a coupling of these modes may lead to larger reconnection rates and thus may explain magnetic flux transfer events at the dayside magnetopause.

The Astrophysical JournalCollisionless tearing instability with a power-law distribution function in a relativistic pair plasma with a guide field is studied. When the current sheet is supported by plasma pressure, the tearing mode is suppressed as the particle spectrum hardens.
