Study on the large scale dynamo transition
, 2010 Using the magnetohydrodynamic (MHD) description, we develop a nonlinear dynamo model that couples the evolution of the large scale magnetic field with turbulent dynamics of the plasma at small scale by electromotive force (e.m.f.) in the induction ...

First Flexible All‐Perovskite Tandem Minimodule Using Au‐Free Recombination Junction
Advanced Photonics Research, Volume 7, Issue 4, April 2026.Through the development of a thin‐indium tin oxide recombination layer with a high lateral resistance combined with a compact SnO2 buffer layer, stacking MA‐free wide bandgap and narrow bandgap subcells is successfully achieved. Also, thanks to the implementation of a suitable laser scribing process, 11 cm2 all‐perovskite tandem minimodules are ...

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 The origins of solar magnetism lie below the visible surface of the Sun, in the highly turbulent convection zone. Turbulent convection operates in conjunction with rotational shear, global circulations and intricate boundary layers to produce the rich diversity of magnetic activity we observe.

Advances in mean-field dynamo theories
, 2012 We give a short introduction to the subject and review advances in understanding the basic ingredients of the mean-field dynamo theory. The discussion includes the recent analytic and numerical work in developments for the mean electromotive force of the

Advanced Science, Volume 13, Issue 23, 23 April 2026.Astrocytic TIA1‐mediated stress granules (SGs) promote demyelination by sequestering the mRNA of cholesterol synthesis genes. In this model, astrocytic TIA1‐mediated SGs were increased in the optic nerves of EAE mice, leading to the downregulation of cholesterol synthesis genes such as HMGCS1 through sequestration of their mRNA into SGs, which ...

Geomagnetism, volcanoes, global climate change, and predictability. A progress report
Annals of Geophysics, 1994 A model is investigated, by which the encounters of the solar system with dense interstellar clouds ought to trigger either geomagnetic field reversals or excursions, that produce extra electric currents within the Earth dynamo, that cause extra Joule's ...

Quasi-biennial oscillations and Rieger-type periodicities in a Babcock–Leighton solar dynamo
Astronomy & AstrophysicsContext. The Sun’s magnetic field exhibits the 11 year solar cycle as well as shorter periodicities, popularly known as the quasi-biennial oscillations (QBOs) and Rieger-type periods.

Intermittent turbulent dynamo at very low and high magnetic Prandtl numbers
, 2011 Context: Direct numerical simulations have shown that the dynamo is efficient even at low Prandtl numbers, i.e., the critical magnetic Reynolds number Rm_c necessary for the dynamo to be efficient becomes smaller than the hydrodynamic Reynolds number Re ...
