Magnetic tornado is stirring up the haze at Jupiter's poles
Magnetic tornado Magnetically Hydrocarbon
2024/12/11
Dark ovals in Jupiter's polar haze, visible only at UV wavelengths, were first noticed 25 years ago, then ignored. A new study shows that these dark UV ovals are common, appearing at the south pole in...
Over fifty years ago, Carl Eckart described the sequence of processes as a passive scalar is stirred and mixed in a turbulent flow (Eckart, 1948). At first, during the stirring phase, the variance of ...
Stirring-up atomtronics in a quantum circuit: What's so 'super' about this superfluid（图）
super a quantum circuit
2014/3/20
While pursuing the goal of turning a cloud of ultracold atoms into a completely new kind of circuit element, physicists have demonstrated that such a cloud-known as a Bose-Einstein condensate (BEC)-ca...
Tidal stirring of Milky Way satellites: a simple picture with the integrated tidal force

Most of dwarf spheroidal galaxies in the Local Group were probably formed via environmental processes like the tidal interaction with the Milky Way.We study this process via N-body simulations of dwar...
Optimal stirring strategies for passive scalar mixing
Optimal stirring strategies passive scalar mixing
2010/12/15
We address the challenge of optimal incompressible stirring to mix an initially inhomogeneous
distribution of passive tracers. As a quantitative measure of mixing we adopt the H1 norm of th...
Topological optimisation of rod-stirring devices
Topological optimisation rod-stirring devices
2010/4/6
There are many industrial situations where rods are used to stir a fluid, or where rods repeatedly stretch a material such as bread dough or taffy. The goal in these applications is to stretch either ...
Stirring Effects on Properties of Al Goethite Formed from Ferrihydrite
Al Goethite Crystallinity Hematite Stirring Unit Cell Parameters
2011/12/8
Abstract: Minerals in surface environments form in both turbulent and non-turbulent systems. This study compares the properties of Al goethite formed from ferrihydrite at 60 °C in 0.3 M KOH with and w...
