A COMBINED FIRST PRINCIPLES AND MOHR-COULOMB CRITERION FOR THE DETERMINATION OF THE NANOHARDNESS OF AMORPHOUS SILICON

A combined first principles and Mohr-Coulomb criterion for the determination of the nanohardness of amorphous silicon

Although, the evaluation of the nanohardness of amorphous silicon (a-Si) has been the subject of a few experimental works but, to date, it has not been addressed theoretically yet.In this work, FSD first principles Kohn-Sham density functional theory (DFT)-based molecular dynamics (MD) in combination with Mohr-Coulomb criterion is employed to calcu

Prefrontal control of attention to threat

Attentional control refers to the regulatory processes that ensure that our actions are in accordance with our goals.Dual-system accounts view temperament as consisting of both individual variation in emotionality (e.g.trait anxiety) and variation in regulatory attentional mechanisms that act Han Pipe to modulate emotionality.Increasing evidence li
