The Lorentz force effect on the On-Off dynamo intermittency [PDF]
, 2007 An investigation of the dynamo instability close to the threshold produced by an ABC forced flow is presented. We focus on the on-off intermittency behavior of the dynamo and the counter-effect of the Lorentz force in the non-linear stage of the dynamo ...

Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae
New Phytologist, Volume 250, Issue 5, Page 2837-2844, June 2026.Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

Triadic resonances in nonlinear simulations of a fluid flow in a precessing cylinder
New Journal of Physics, 2015 We present results from three-dimensional nonlinear hydrodynamic simulations of a precession driven flow in cylindrical geometry. The simulations are motivated by a dynamo experiment currently under development at Helmholtz-Zentrum Dresden-Rossendorf in ...

External Forcing of the Solar Dynamo
Frontiers in Astronomy and Space Sciences, 2022 In this paper I examine whether external forcing of the solar dynamo on long timescales can produce detectable signal in the form of long term modulation of the magnetic cycle.

Protein Science, Volume 35, Issue 5, May 2026.Abstract Cryo‐electron tomography (cryoET) enables visualization of macromolecular complexes within intact cellular environments. Continued improvements in instrumentation, sample preparation, and data‐processing pipelines have increased both the scale and the complexity of cryoET datasets, making manual analysis challenging.

Feasibility of a magma ocean dynamo on Mars
Progress in Earth and Planetary Science, 2017 Crustal magnetization of rocks in regions of Mars surface testifies to an era of dynamo activity. I examine the possibility that the dynamo that operated then, in the first 400–600 Ma after Mars formed, was powered by a crystallizing subsurface magma ...

Prograde and retrograde precession of a fluid-filled cylinder
New Journal of Physics, 2021 We numerically study precession driven flows in a cylindrical container whose nutation angle varies between 60 and 90 degrees for prograde and retrograde precession.

Does the butterfly diagram indicate asolar flux-transport dynamo?
, 2004 We address the question whether the properties of the observed latitude-time diagram of sunspot occurence (the butterfly diagram) provide evidence for the operation of a flux-transport dynamo, which explains the migration of the sunspot zones and the ...

Kinematic dynamo action in a sphere. II. Symmetry selection [PDF]
, 2000 The magnetic fields of the planets are generated by dynamo action in their electrically conducting interiors. The Earth possesses an axial dipole magnetic field but other planets have other configurations: Uranus has an equatorial dipole for example.
