The Geodetic Response to Magma Thermal Modulation During Drilling
Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract We report surface displacements and gravity changes triggered by thermal modulation of shallow‐seated (∼ ${\sim} $2 km depth) silicic magma lenses during drilling. 2D plane strain models predict ground subsidence of up to 20 cm and net gravity increases of up to 82 μ $\mu $Gal from the thermal contraction of a thin (0.01 aspect ratio) sheet ...

Axial confinement in the Novatron mirror machine
Nuclear FusionThe 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 ...

Auroral Ionospheric Erosion at Jupiter
Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.Abstract The generation of Jupiter's main auroral oval is dominated by broadband‐energy electron beams, in contrast with the dominance of peaked electron energy spectra at Earth. Wave‐particle interactions involving Alfvén waves have been theorized to be the main mechanism driving the broadband acceleration of electrons.

Spectral approach to axisymmetric evolution of Einstein's equations
, 2015 We present a new formulation of Einstein's equations for an axisymmetric spacetime with vanishing twist in vacuum. We propose a fully constrained scheme and use spherical polar coordinates.

Supersonic flows of the Euler–Poisson system with nonzero vorticities in three‐dimensional cylinders
Journal of the London Mathematical Society, Volume 112, Issue 1, July 2025.Abstract We prove the unique existence of three‐dimensional supersonic solutions to the steady Euler–Poisson system in cylindrical nozzles. First, we establish the unique existence of irrotational solutions in a cylindrical nozzle with an arbitrary cross‐section with using weighted Sobolev norms.

Indentation and Puncturing of Pristine and Flawed Soft Membranes
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 6, Page 2787-2800, June 2025.ABSTRACT This paper investigates the mechanical behavior of soft elastomeric membranes under indentation by a rigid spherical object, with a particular focus on the failure mechanisms leading to puncture. The study examines both pristine membranes and those with pre‐existing flaws, such as cracks, to explore how these imperfections affect the ...

Influence of Laser Energy Deposition Conditions on the Drag of A Sphere in Supersonic Flow
Energies, 2019 In the present study, a two-dimensional axisymmetry unsteady numerical simulation that implements high-frequency laser energy deposition was performed to understand its influence on drag reduction in supersonic flow.

Anisotropy in Homogeneous Rotating Turbulence
, 2003 The effective stress tensor of a homogeneous turbulent rotating fluid is anisotropic. This leads us to consider the most general axisymmetric four-rank ``viscosity tensor'' for a Newtonian fluid and the new terms in the turbulent effective force on large

Design of 3D equilibria and coils for steady-state operation of tokamaks
Nuclear FusionInspired by the respective advantages of tokamaks and stellarators, we propose a quasi-axisymmetric (QA) tokamak-stellarator hybrid concept as a steady-state operation mode of standard tokamaks.
