We determine the trajectories of liquid particles under an ice cover in the field of a nonlinear surface traveling wave rapidly decaying at infinity, namely, a solitary wave packet (a monochromatic wave under the envelope, with the wave velocity equal to the envelope ...
Its motion is subjected to the time reversibility of creeping flows. We investigate how this worm reacts to this reversibility condition in order to break the flow symmetry and move in the surrounding fluid. We show that the relationship between the length of an individual nematode and the ...
Suppose if photons are mass less, how it can travel, for anything to move from one place to another, some presence is needed. Hence to support the above argument let us consider photons have mass. It is believed Electron is indivisible. Now, here, we will see that electron can be ...
To demonstrate this possibility, we investigate how the motion of microparticles along helical trajectories can influence their transport through a crosslinked cellulose membrane (Fig. 6, Supplementary Movie 5). A chamber between two parallel electrodes is divided into two compartments A and B by a ...
Recently, one of the authors proposed a very convenient formula to evaluate the friction coefficient induced by wave-current combined motion, which spans all flow regimes including the transitional regime and requires no iteration. This ... H Tanaka,VT Dang - 《Coastal Engineering》 被引量: 29发...
The accelerator is so designed that, during the first part of the acceleration, the electrons are caused to gather into bunches, which then are accelerated nearly to the speed of light. Subsequently, the electrons move with the crest of the electromagnetic wave. Linear electron accelerators are ...
(black arrows) is along the tangential component of blue arrows; thus, the moving direction reverses when the blue arrow becomes normal to the obstacle surface att1. When the blue arrow is parallel to the obstacle surface att2(i.e., the normal component of the blue arrow is not against ...
Quantum mechanics allows a particle to move without practical possibility of being found at the intermediate area. Here we demonstrate this spatial adiabatic passage with ultracold atoms in an optical lattice. Key to this is the existence of dark eigenstates forming a flat energy band, with ...
