Exchange coupling coefficient and domain wall mobility of (Dy,Tb)FeCo magneto-optical films
2011/11/30
The magnetic properties and recording characteristics of ~Dy,Tb!FeCo films are dependent upon the anisotropy dispersion of rare earth constituents and the exchange integral between rare earth and tran...
Recurrent host mobility in spatial epidemics: beyond reaction-diffusion
beyond reaction-diffusion spatial epidemics
2011/9/2
Human mobility is a key factor in spatial disease dynamics and related phenomena. In computational models host mobility is typically modeled by diffusion in space or onmetapolulation networks. Alterna...
