Empirical patterns that emerge from an examination of food webs over gradients of environmental variation can help to predict the implications of anthropogenic disturbance on ecosystems. This "dynamic food web approach" is rarely applied at the coastal margin where aquatic and terrestrial systems are coupled and human development activities are often concentrated. We propose a simple model of g...

In this paper, we present a combined immersed-boundary/ghost-fluid sharp interface method for the simulations of three-dimensional two-phase flows interacting with moving bodies on fixed Cartesian grids. This work is based on a sharp interface immersed boundary method for fluid flows interacting with moving bodies and a level set based ghost fluid method (GFM) for two-phase interface treatment....

Ghost cell differentiation within an ameloblastic fibroma is extremely rare. The ghost cells found in an ameloblastic fibroma in previously reported cases were all associated with a typical calcifying odontogenic cyst. Here, we report a case of an ameloblastic fibroma with focal ghost cells and calcifications in some neoplastic epithelial islands, but without other histologic manifestations con...
