Living near high-voltage power lines and exposure to high-frequency electromagnetic fields (EMFs) is a potential serious hazard to animal and human health. The present study was carried out to evaluate the effect of high-frequency EMFs from simulated high-voltage electric towers on cognitive, anatomical, and biological changes in male Macaque. In this study, two Rhesus Macaque were recruited, ...

Electromagnons, which are coupled polar and magnetic excitations in magnetoelectric materials, of large interest for electronic computing technological devices. Using molecular dynamics simulations based on an ab initio effective Hamiltonian, we predict that the frequency several electromagnons can be tuned by application electric fields model multiferroic ${\mathrm{BiFeO}}_{3}$, with this eith...

This paper aims to find the efficient state of hybrid electric vehicle (HEV) by simultaneous optimization of the control strategy and the power train. The power transmission employed in this vehicle is a power-split continuously variable transmission (CVT) which uses several fixed ratio mechanisms. After describing this transmission, the rules of electric assist control strategy are introduced....
