A robust diffusion-based gradient generator for dynamic cell assays.

January 1, 2012
Author(s)
Francisco J. Atencia, Gregory A. Cooksey, Laurie E. Locascio
This manuscript describes a new method to generate purely diffusive chemical gradients that can be modified in time. The device is simple in its design and easy to use, which makes it amenable to study biological processes that involve static or dynamic

Accessibility of Pores in Coal to Methane and Carbon Dioxide

January 1, 2012
Author(s)
Yuri B. Melnichenko, Lilin He, Richard Sakurovs, Arkady L. Kholodenko, Tomasz Blach, Maria Mastalerz, Andrzej P. Radlinski, Gang Cheng, David F. Mildner
Fluid-solid interactions in natural and engineered porous solids underlie a variety of technological processes, including geological storage of anthropogenic greenhouse gases, enhanced coal bed methane recovery, membrane separation, and heterogeneous

First Variation of the General Curvature-dependent Surface Energy

January 1, 2012
Author(s)
Gunay Dogan, Ricardo H. Nochetto
We consider general weighted surface energies, where the energies have the form of weighted integrals over a closed surface and the weight depends on the normal and the mean curvature of the surface. Energies of this form have applications in many areas

Model-Based Interpolation, Prediction, and Approximation

January 1, 2012
Author(s)
Antonio M. Possolo
Model-based interpolation, prediction, and approximation are contingent on the choice of model: since multiple alternative models typically can reasonably be entertained for each of these tasks, and the results are correspondingly varied, this often is a
