As in all collisions, momentum is conserved in this example. But calculations comparing kinetic energy before and after the collision show kinetic energy is not conserved. This is an inelastic ...

There is enormous interest in engineering topological photonic systems. Despite intense activity, most works on topological photonic states (and more generally bosonic states) amount in the end to ...

The purposes of this study were to (1) investigate compression levels beneath an inelastic legging equipped with a new pressure-adjustment system, (2) compare the inelastic compression levels with ...
