Juno Observations of Large‐Scale Azimuthal Fields and Flows in Jupiter's Nightside Magnetosphere: Field‐Aligned Currents, Effective Ionospheric Pedersen Conductivity, and Power to Atmospheric Heating

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Using the methodology of Cowley et al. (https://doi.org/10.1029/2025JA033993), we employ ∼8 years of Juno azimuthal magnetic field data to derive colatitude profiles of Jupiter's nightside (17‐05 hr via midnight) ionospheric equatorward Pedersen current from near the magnetic pole to inner magnetosphere field lines at 18° colatitude, from ...

SymmPi: Exploiting Symmetry Removal for Fast Subgraph Matching

Data Science and Engineering
Symmetry, a phenomenon of self-similarity, is common in many networks, which often incurs a lot of redundant accesses and computations, even duplicate results when executing graph matching tasks. Many approaches (e.g.

Kinematic diagnostics for non-axisymmetry in the Milky Way’s nuclear stellar disc

Astronomy & Astrophysics
There is now strong evidence that the Milky Way (MW) hosts a nuclear stellar disc (NSD). However, whether the NSD is purely axisymmetric or contains a nuclear bar remains unresolved.

Axisymmetry of mantle aspherical structures

Geophysical Research Letters, 1995
Recent seismic tomographic models have revealed broad, low velocity anomalies in the lower mantle beneath Africa and the central Pacific that correspond to the poles of the surface geotectonic reference network. We test the hypothesis that the tomographic models are axisymmetrical with respect to axes passing near the geotectonic poles. The symmetry is

Frequency Analysis of a Superconducting Magnetic Bearing System in Ring Spinning Using an Eddy Current Damper

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT The conventional ring‐spinning process has been used for over a century, being one of the most used processes in the textile industry. However, this process has some disadvantages at high spindle speeds, such as friction in the traveler/ring components that generates heat, resulting in yarn breakages or lower‐quality production.

Comparison of Analytical and FFT‐Based Predictions of Effective Stiffness in Isotropic and Anisotropic Closed‐Cell Materials

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT This work investigates the elastic behavior of isotropic and anisotropic closed‐cell porous materials using analytical and Fast‐Fourier‐Transform (FFT)‐based numerical approaches. The study focuses on understanding how microstructural features, such as pore shape, orientation, and solid volume fraction, influence the macroscopic stiffness of ...

Early Solar Wind and Dynamo Magnetic Field Topology Predictions for (16) Psyche and Other Asteroids

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Asteroid (16) Psyche is a metal‐rich body that might record an ancient coherent magnetization if some relict crust or mantle is preserved. Herein, we use magnetohydrodynamic simulations to predict (16) Psyche's field topology for several distinct pathways: (i) an early solar wind‐induced magnetization imparted after a larger body was impacted,

Axial confinement in the Novatron mirror machine

Nuclear Fusion
The Novatron magnetic mirror fusion reactor concept features significant advantages. These include stability against MHD interchange and kinetic drift cyclotron loss cone modes, axisymmetry, and minimized radial particle drifts and neoclassical losses ...

A Lagrangian Description of Pulsation, Tilting, Axisymmetrization, and Meandering Trajectory in an Anticyclonic Eddy

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Mesoscale eddies pulsate, tilt with depth, and deform, but these processes are rarely resolved together from multi‐depth Lagrangian observations. We analyze a long‐lived intrathermocline anticyclonic eddy in the Canary Eddy Corridor using four drifters spanning 15–150 m and a novel, position‐only ellipse‐fitting method based on axis‐aligned ...
