New findings suggest that ordinary sound has negative gravitational mass. This is an Inside Science story. (Inside Science) -- The sound of a sonic boom may produce about the same magnitude of ...
Time-domain finite-difference (TDFD) method is the most dominant approach for seismic wavefield simulation. Due to the memory and computational cost of the computer, finite-difference (FD) simulations ...
Figure 1: Steady states of polar active liquids in coupled annular channels. Figure 2: Dispersion of density waves in active metamaterials either with or without topological edge states. We examined ...
