Phase-slips and vortex dynamics in Josephson oscillations between Bose-Einstein condensates [PDF]
, 2014 We study the relation between Josephson dynamics and topological excitations in a dilute Bose-Einstein condensate confined in a double-well trap. We show that the phase slips responsible for the self-trapping regime are created by vortex rings entering ...

Vortex dynamics and Reynolds number effects of an oscillating hydrofoil in energy harvesting mode [PDF]
Journal of Fluids and Structures, 2018 The energy extraction potential from the sinusoidal heaving and pitching motion of an elliptical hydrofoil is explored through direct numerical simulations (DNS) at a Reynolds number of 1,000 and large eddy simulations (LES) at a Reynolds number of 50 ...

Thermal dissipation in quantum turbulence
, 2006 The microscopic mechanism of thermal dissipation in quantum turbulence has been numerically studied by solving the coupled system involving the Gross-Pitaevskii equation and the Bogoliubov-de Gennes equation. At low temperatures, the obtained dissipation

Flickering of buoyant diffusion flames: a vortex dynamics revisit [PDF]
, 2018 Previous studies have found that the flickering of buoyant diffusion flames is associated with the periodic shedding of a toroidal vortex, which is formed under gravity-induced shearing at the flames.

Understanding liquid-jet atomization cascades via vortex dynamics [PDF]
Journal of Fluid Mechanics, 2017 Temporal instabilities of a planar liquid jet are studied using direct numerical simulation (DNS) of the incompressible Navier–Stokes equations with level-set (LS) and volume-of-fluid (VoF) surface tracking methods.

Guiding-center dynamics of vortex dipoles in Bose-Einstein condensates
, 2011 A quantized vortex dipole is the simplest vortex molecule, comprising two counter-circulating vortex lines in a superfluid. Although vortex dipoles are endemic in two-dimensional superfluids, the precise details of their dynamics have remained largely ...

Thermal vortex dynamics in thin circular ferromagnetic nanodisks [PDF]
, 2012 The dynamics of gyrotropic vortex motion in a thin circular nanodisk of soft ferromagnetic material is considered. The demagnetization field is calculated using two-dimensional Green's functions for the thin film problem and fast Fourier transforms.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Aerospace, 2019 The maneuverability of the Sukhoi Su-30 at very high angles of attack (AoA) was remarkably appealing. Canard angle, in cooperation with aircraft wing, created a flow pattern whereby, in that position, the fighter still had as much lifting force as ...
