Downlink coverage analysis in a heterogeneous cellular network [PDF]

2012 IEEE Global Communications Conference (GLOBECOM), 2012
In this paper, we consider the downlink signal-to-interference-plus-noise ratio (SINR) analysis in a heterogeneous cellular network with K tiers. Each tier is characterized by a base-station (BS) arrangement according to a homogeneous Poisson point process with certain BS density, transmission power, random shadow fading factors with arbitrary ...

Heterogeneous force network in 3D cellularized collagen networks [PDF]

Physical Biology, 2016
Collagen networks play an important role in coordinating and regulating collective cellular dynamics via a number of signaling pathways. Here, we investigate the transmission of forces generated by contractile cells in 3D collagen-I networks. Specifically, the graph (bond-node) representations of collagen networks with collagen concentrations of 1, 2 ...
