A theory for large amplitude compressional electromagnetic solitary pulses in a magnetized electron-positron (e-p) plasma is presented. The pulses, which propagate perpendicular to the external magnetic field, are associated with the compression of the plasma density and the wave magnetic field. Here the solitary wave magnetic field pressure provides the restoring force, while the inertia comes...

Mechanical forces acting on focal adhesions (FAs) are believed to be an important determinant for cytoskeletal reorganization. However, the effect of the temporal pattern of forces on cellular responses has not been elucidated. In the present study, we examined the responses of FAs to locally-applied cyclic forces. Magnetic micro beads coated with fibronectin were attached to the apical surface...

An annoying tonal noise is produced by modern electrical trains during acceleration and deceleration. This noise is caused by electromagnetic forces generating structural vibrations, especially from the traction motors. The electromagnetic noise is dominant at low train speeds and affects both the passengers on the train and on platforms, as well as people living near the track. The focus on th...
