This paper presents a Pore Network Model (PNM) based methods for design scaffold. In this modeling process, plenty of unit spheres that distributed in space coordinate randomly with different diameter within limits are created and permeated into the whole scaffold space. When the total volume proportion of the unit spheres ascends to a certain value, a PNM model is formed with the topological structure...
A great portion of data on the Web lies in the hidden databases of the deep Web. These databases can only be accessed through the query interfaces.
