In planar structures, the vortex resonance frequency changes little as a function of an in-plane magnetic field as long as the vortex state persists. Altering the topography of the element leads to a vastly different dynamic response that arises due to the local...

It is believed that bulk gold metal is chemically inert and the most stable metal in nature. However, its properties in the nano size region might be different from its bulk nature because the electronic structure may be modified significantly. In fact, recent...

The effects of weak magnetic fields on the biological production of reactive oxygen species (ROS) from intracellularsuperoxide (O2 N2) and extracellular hydrogen peroxide (H2O2) were investigated in vitro with rat pulmonary arterial smooth muscle cells (rPASMC). Spin...

In the present study we analyze the role of polarization in the biological activity of Electromagnetic Fields (EMFs)/Electromagnetic Radiation (EMR). All types of man-made EMFs/EMR – in contrast to natural EMFs/EMR – are polarized. Polarized EMFs/EMR can...
