ABSTRACT We derive a simple prescription for including beyond-linear halo bias within the standard, analytical halo-model power spectrum calculation. This results in corrective term that is added to usual two-halo term. measure this correction using data from N-body simulations and demonstrate it can boost by factor of ∼2 at scales $k\sim 0.7\, h\mathrm{Mpc}^{-1}$, with exact magnitude determin...

This paper considers metapopulation models in the general sense, i.e. where the population is partitioned into sub-populations (groups, patches,...), irrespective of the biological interpretation they have, e.g. spatially segregated large sub-populations, small households or hosts themselves modelled as populations of pathogens. This framework has traditionally provided an attractive approach t...
