Stability of Relative Equilibria of Point Vortices on the Sphere [PDF]
, 2005 We describe the linear and nonlinear stability and instability of certain configurations of point vortices on the sphere forming relative equilibria. These configurations consist of up to two rings, with and without polar vortices.

Two-dimensional para-, ortho-, and bi-magnetoexcitons interacting with quantum point vortices
Moldavian Journal of the Physical Sciences, 2018 The theory of two-dimensional (2D) magnetoexcitons was enlarged taking into account the electron–hole (e–h) exchange Coulomb interaction, which appears when the conduction and valence electrons belong partially to both bands.

Vortex Avalanches and Collective Motion in Neutron Stars
The Astrophysical JournalWe simulate the dynamics of about 600 quantum vortices in a spinning-down cylindrical container using a Gross–Pitaevskii model. For the first time, we find convincing spatial-temporal evidence of avalanching behavior resulting from vortex depinning and ...

AIP Advances, 2019 Sideslip-induced asymmetrical vortices are critical to the performance of canard-configuration aircraft. In this paper, a canard-configuration model was found to roll around a nonzero trim angle in a free-to-roll experiment, indicating a loss of lateral ...

A 3D Human Neuron‐on‐Chip Platform to Monitor Neuronal Injury Responses
Advanced Healthcare Materials, EarlyView.This study presents a novel 3D Neuron‐on‐Chip model that can maintain human PSC‐derived excitatory prefrontal cortex neurons in 3D hydrogels and can be used to monitor neuronal injury responses over time. Results show injury‐induced acute neuronal excitotoxicity, declining neuronal connectivity, and the activation of a neurodegenerative, SASP‐like ...

Geometric flows on soliton moduli spaces [PDF]
, 2013 It is well known that the low energy dynamics of many types of soliton can be approximated by geodesic motion on Mn, the moduli space of static n-solitons, which is usually a Kähler manifold.

Periodic steady vortices in a stagnation-point flow [PDF]
, 1994 A stagnation point flow of the form U = (0, Ay, - Az) is unstable to three-dimensional disturbances. It has been shown that the vorticity components of such a disturbance that are perpendicular to the direction of the diverging flow will decay, and that ...

Potential Type Operators on Curves with Vorticity Points
Zeitschrift für Analysis und ihre Anwendungen, 1999 We study potential type operators on certain non-Lipschitz curves \Gamma . The curves under consideration are locally Lyapunov except for a finite set F of singular ...
