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

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Turbulence Trigger for Neoclassical Tearing Modes in Tokamaks

, 2003
"Stochastic trigger by microturbulence for neoclassical tearing mode (NTM) is studied. NTM induces topological change of magnetic structure and has subcritical nature.

Fast Tearing Mode Driven by Demagnetized Electrons

Geophysical Research Letters
Recent MMS observations have discovered electron‐scale super‐thin current sheets (STCSs) with a partial electron demagnetization, which distinguishes them from the ion‐scale TCSs traditionally observed by the Cluster mission. Our investigation focuses on

Dynamical modelling of neoclassical tearing mode suppression by ECCD

EPJ Web of Conferences, 2012
The rotation of a magnetic island through the EC power deposition region in combination with a finite collisional time scale on which the EC power is converted into current are shown to affect the NTM stabilization by ECCD. In particular, the stabilizing

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Sawtooth triggering of a disruptive 2/1 tearing mode in HBT-EP is controlled by wall stabilization and sawtooth period

Nuclear Fusion
This work characterizes the sudden appearance of a sustained, disruptive 2/1 tearing mode after a sawtooth crash, from a preexisting low-amplitude coupled 2/1–3/1 tearing-kink mode, on the HBT-EP tokamak. Using HBT-EP’s radially movable resistive wall we

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
