The magnetic flux rope is among the most fundamental magnetic configurations in plasma. Although its presence after solar eruptions has been verified by spacecraft measurements near Earth, its formation on the Sun remains elusive, yet is critical to unde
Space‐Charge‐Wave Decay Along a Signal‐Current‐Excited Multivelocity Beam A previous analysis of noise propagation along a drifting electron beam with a half‐Maxwellian distribution of velocities is specialized here to apply to ... S Bloom,B Vural - 《Journal of Applied Physics》 被引量: ...
Step 1: Set the initial temperature, and initialize the population along with every particle velocity and position. Step 2: Compute 𝑭(𝑝𝑖) (𝑖=1,..,𝑁)F(pi) (i=1,..,N), where N is the updated population. Step 3: Update the present position and fitness value of each part...
The free ends of the stripes were gripped by claws of the ZD 10 (W + B) tensile tester and pulled away with the velocity of 20 mm/min. 2.4. Plasma Diagnostics Optical emission spectra were recorded by Andor spectrometer model Shamrock 500i coupled to CCD Andor Newton detector (EMCCD DU...
We set and the lattice spacing to unity and thus measure time, velocity and particle current in the appropriate units in terms of the hopping matrix element. We prepare initial states as the ground state of H = H0 + Hconf [8]. We consider two cases: First, the expan- sion from a ...

Bottom panel: kymograph from Video S9 with D. discoideum front advancement indicated by red arrowheads and F. alba front advancement by yellow arrowheads. (F, G, I, and J) The n values in (G and J) are the number of velocity data points during the trajectory time and also correspond ...
I have this "negative power of zero" problem...it only goes away when I put an "artificial" inlet and outlet, but then it would keep saying me "stiffness matrix with NaN/inf" numbers. One problem instead of another; actually I do not know if it would still tell me about the ...
1【题目】A particle is projected from a point o, with an initial velocity of u m s-1, at an angle of ato the horizontal. In the vertical plane of projection, taking and y as the horizontal and vertical axes respectively Given that u=42 and that the particle passes through the point ...
