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 ...

Clinical &Translational Immunology, Volume 15, Issue 3, 2026.This study developed a prognostic model for lung adenocarcinoma using manganese metabolism‐related genes (MRGs). Nine key MRGs were identified via multi‐omics and LASSO‐Cox analyses to calculate a risk score. The model showed robust predictive performance in both training and validation cohorts.

Membrane lipid composition modulates the organization of VDAC1, a mitochondrial gatekeeper
Communications BiologyVDACs, the most abundant proteins in the outer mitochondrial membrane (MOM), are crucial for mitochondrial physiology. VDAC regulate metabolite and ion exchange, modulate calcium homeostasis, and play roles in numerous cellular events such as apoptosis ...

Small-scale dynamos in simulations of stratified turbulent convection
, 2018 Small-scale dynamo action is often held responsible for the generation of quiet-Sun magnetic fields. We aim to determine the excitation conditions and saturation level of small-scale dynamos in non-rotating turbulent convection at low magnetic Prandtl ...

Global GNSS Observation of Mesoscale Ionospheric Irregularities (2006–2024)
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Mesoscale ionospheric irregularities are statistically investigated using an unprecedented 19‐year long‐term global GNSS (Global Navigation Satellite System) TEC (total electron content) data set. These irregularities are represented by ionospheric fluctuations within a 5°× ${}^{\circ}\times $ 3.75° ${}^{\circ}$ (latitude by longitude) region ...

Physics of Plasmas, 2002 A new kind of dynamo utilizing flowing laboratory plasmas has been identified. The conversion of plasma kinetic energy to magnetic energy is verified numerically by kinematic dynamo simulations for magnetic Reynolds numbers above 210. As opposed to intrinsically-turbulent liquid-sodium dynamos, the proposed plasma dynamo corresponds to laminar flow ...

Nonlinear dynamo in a short Taylor-Couette setup
, 2012 It is numerically demonstrated by means of a magnetohydrodynamics code that a short Taylor-Couette setup with a body force can sustain dynamo action. The magnetic threshold is comparable to what is usually obtained in spherical geometries.

Magnetic Evolution of Super‐Earth Exoplanets With a Basal Magma Ocean
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Habitability of super‐Earths likely requires self‐sustained magnetic fields to shield their atmospheres from stellar forcing. Extreme pressures and temperatures probably produce a long‐lived basal magma ocean (BMO), a potential source for these fields.
