On the mean-field theory of the Karlsruhe Dynamo Experiment [PDF]
Nonlinear Processes in Geophysics, 2002 In the Forschungszentrum Karlsruhe an experiment has been constructed which demonstrates a homogeneous dynamo as is expected to exist in the Earth's interior. This experiment is discussed within the framework of mean-field dynamo theory.

New Phytologist, Volume 252, Issue 1, Page 145-162, October 2026.Long‐read whole‐genome sequencing revealed extensive chromosomal rearrangements and aneuploidy in a widely used Chlamydomonas reinhardtii stt7‐1 mutant. The STT7 gene (shown in red) was found to be split between two rearranged chromosomes, providing a molecular explanation for the long‐standing failure of this mutant in genetic crosses.

The Malkus-Robbins dynamo with a nonlinear motor [PDF]
, 2004 In a recent paper Moroz \cite{m02} considered a simplified version of the third class of self-exciting Faraday-disk dynamo model, introduced by Hide \cite{h97}, in the limit in which the Malkus-Robbins dynamo \cite{m72,r77} results as a special case.

A model for rapid stochastic distortions of small-scale turbulence [PDF]
, 2004 We present a model describing the evolution of the small-scale Navier–Stokes turbulence due to its stochastic distortion by much larger turbulent scales. This study is motivated by numerical findings (Laval et al. Phys. Fluids vol. 13, 2001, p.

How life affects mineral formation: A reappraisal of concepts and terminology
The Depositional Record, Volume 12, Issue 4, September 2026.We present a moderately revised terminology of concepts how life may influence mineral formation. This framework would be more consistent and universally applicable. Abstract Numerous biological factors have been proposed to influence the formation of minerals under Earth‐surface conditions, but the underlying concepts are often confused due to ...

Bayesian inference methods for the calibration of stochastic dynamo models
, 2019 In essentially all applied sciences, data-driven modeling heavily relies on a sound calibration of model parameters to measured data for understanding the underlying mechanisms that lead to observed features.

Prediction‐Based Algorithms for Long‐Range High‐Speed Force Spectroscopy
Journal of Molecular Recognition, Volume 39, Issue 5, September 2026.ABSTRACT We present a high‐speed force microscopy platform mounted on a confocal microscope with a z sample stage enabling long‐range, high‐speed force spectroscopy measurements on biological samples. The control software is built on a field‐programmable gate array (FPGA)‐based data acquisition and processing system, complemented with a custom ...

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 ...

No-z Model for Magnetic Fields of Different Astrophysical Objects and Stability of the Solutions
Data, 2021 A wide range of astrophysical objects, such as the Sun, galaxies, stars, planets, accretion discs etc., have large-scale magnetic fields. Their generation is often based on the dynamo mechanism, which is connected with joint action of the alpha-effect ...
