In this work, we introduce a new type of granular CAPs, namely, grass seeds, to tackle the above scientific questions. These seed particles are smaller and lighter than previous man-made granular CAPs and are thus suitable for studying CAP motions in obstacle arrays. We investigate how CAPs a...
All solutions of the equations of motion in the absence of external fields were found, and besides, we give more precise definition of a free object. It turns out that the massive particles always possess a longitudinal polarization. There are possible transversal motions of the following types:...
The properties of the interactions of faster-than-light particles (tachyons) with ordinary matter are discussed both in the framework of a classical closed causal cycle and in a field-theoretical formalism constrained by the reinterpretation principle. It is concluded that such interactions, if they...
Because we have a random delay, the particles waiting to start their animation are visible on the top-left of the screen. To prevent this, we can set a zero opacity on every particle in our global CSS. particle{/* Same as before */opacity:0;} ...
how to track particle world within footage to make the particles look like they are emitting from a point deep in z space and then flying toward the camera, but in a way that looks like they're interacting with the scene. I have a still scene set up, ...
are in continuous motion. The stresses generated by the spinners through the corona are released in these regions. To relax the stresses they need to yield. Figure 5: Effect of the spinners in a passive monolayer ofϕA=0.8. (a,b) Illustration showing the forces on the system and the ...
The most studied active agents are those which convert some sort of energy into translational motion. Such systems resemble how bacteria swim, and are known as self-propelled agents6,7,10–11. Energy conversion into rotational motion is also common in nature; important examples are the motor ...
The mechanics which governs atomic phenomena—quantum mechanics or wave mechanics—is based on ideas of motion, which are fundamentally different from those of classical mechanics. In quantum mechanics, there is no such concept as the path of a particle. This forms the content of what is called...
