Rotational symmetry vs. axisymmetry in shell theory [PDF]

open access: yesInternational Journal of Engineering Science, 2010
This paper treats rotationally symmetric motions of axisymmetric shells. It derives the governing equations in a convenient form and determines their mathematical structure. The complicated governing equations have the virtue of the far simpler equations for axisymmetric motions that there is but one independent spatial variable.

Suppressing Stitching Errors in Full‐Sensor‐Plane Color Routers via Optical Structural Similarity

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
Angle‐specific nanophotonic color routers are assembled from a library of inverse‐designed unit cells matched to local incidence angles. Optical structural similarity (OSS) constrains neighboring permittivity profiles during optimization, suppressing inter‐cell stitching errors without additional full‐wave simulations and enabling oblique‐incidence ...

Force-free Wave Interaction in Magnetar Magnetospheres: Computational Modeling in Axisymmetry

open access: yesThe Astrophysical Journal
Crustal quakes of highly magnetized neutron stars can disrupt their magnetospheres, triggering energetic phenomena like X-ray and fast radio bursts. Understanding plasma wave dynamics in these extreme environments is vital for predicting energy transport

Beyond goniometry: 3D digital twinning of droplets from a single image

open access: yesDroplet, Volume 5, Issue 3, July 2026.
We present a method to produce physics‐informed three‐dimensional digital twins of droplets from a single image for wettability analyses. We validate the method with goniometry and demonstrate its capabilities with advancing‐receding contact angle measurements, irregularly shaped droplets, and multi‐droplet systems, indicating strong potential for in ...

Stellar halo striations from assumptions of axisymmetry

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT Motivated by the Large Magellanic Cloud (LMC)’s impact on the integral of motion space of the stellar halo, we run an N-body merger simulation to produce a population of halo-like stars. We subsequently move to a test-particle simulation, in which the LMC perturbs this debris.

Slowly Rotating Traversable Wormholes Supported by Radially Varying String‐Fluid Matter: From Regular Geometries to Photon Trajectories

open access: yesAnnalen der Physik, Volume 538, Issue 6, June 2026.
This study examines slowly rotating traversable wormholes supported by string fluids whose properties change with radius. The matter smoothly shifts from a de Sitter‐like core to a string‐dominated exterior, producing a regular, horizon‐free spacetime.

Enhancement of betatron x rays through asymmetric laser wakefield generated in transverse density gradients

open access: yesPhysical Review Accelerators and Beams, 2018
Laser wakefield acceleration of electrons usually offers an axisymmetry around the laser propagation axis. Thus, the accelerating electrons that are focused on axis often execute small transverse oscillations.

Energetic particle optimization of quasi-axisymmetric stellarator equilibria

open access: yesNuclear Fusion, 2022
An important goal of stellarator optimization is to achieve good confinement of energetic particles such as, in the case of a reactor, alphas created by deuterium–tritium fusion. In this work, a fixed-boundary stellarator equilibrium was re-optimized for

Centrosymmetric‐ and Axisymmetric‐Patterned Flexible Tactile Sensor for Roughness and Slip Intelligent Recognition

open access: yesAdvanced Intelligent Systems, 2022
Next‐generation robots are being designed to function autonomously in complex and unstructured environments. In particular, based on the real‐time measurement and differentiation of normal pressure and shear force, robots can be equipped with the ...
