Tearing analysis of PVC coated fabric under uniaxial and biaxial central tearing tests

Journal of Industrial Textiles, 2022
In this study, detailed uniaxial and biaxial central tearing tests of a type of PVC coated polyester fiber fabric for buildings were carried out. The characteristics of the damage morphology, the formation of the triangle area at the crack tip, crack ...

Effect of Heating on the Suppression of Tearing Modes in Tokamaks [PDF]

Physical Review Letters, 2007
The suppression of (neoclassical) tearing modes is of great importance for the success of future fusion reactors like ITER. Electron cyclotron waves can suppress islands, both by driving noninductive current in the island region and by heating the island, causing a perturbation to the Ohmic plasma current.

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 ...

Nonlinear evolution of weakly coupled double tearing modes with equilibrium sheared toroidal flow

Nuclear Fusion
The nonlinear evolution of weakly coupled double tearing modes (DTMs) with and without sheared toroidal flow is systematically investigated with the three-dimensional, toroidal-geometry, and nonlinear magneto-hydro-dynamics code CLT. Due to the explosive

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

The onset distribution of rotating tearing modes and its consequences on the stability of high-confinement-mode plasmas in DIII-D

Nuclear Fusion, 2023
Analysis of a multi-scenario database of over 13 000 DIII-D H-mode discharges shows that the $m,n = 2,1$ magnetic islands are dominantly pressure gradient driven, stochastically triggered non-linear instabilities at all edge safety factor ( $q_\text{95}$

Macroscopic trends of neoclassical tearing stability in high-field H-mode tokamak pilot plants

Nuclear Fusion
The neoclassical tearing mode (NTM) stability metric—minimum marginally stable island width $w_m^*$ —was compared across 14651 inductive high-field tokamak pilot plant equilibria.

Micro-tearing mode dominated electron heat transport in DIII-D H-mode pedestal

Nuclear Fusion, 2023
A new, comprehensive set of evidence reveals that Micro-Tearing Modes (MTMs) dominate pedestal electron heat transport in an H-mode experiment in the DIII-D tokamak. The experiment investigates the role of MTMs by scanning pedestal collisionality, a main
