mailto:muthu@polysci.umass.edu AbstractCellular behavior is encoded and controlled by complex genetic networks. Synthetic genetic devices that interface with native pathways can be used to change natural networks to implement new forms of control and behavior. Significant recent work on the engineering of synthetic gene networks has been limited by an inability to interface with native networks and components. To overcome these limitations, we have developed RNA control devices that process and transmit molecular signals that are received by integrated sensor domains to targeted protein level outputs, linking computation and logic to gene expression and thus cellular behavior in mammalian cells. The modularity inherent in our device design supports the rational assembly of these RNA controllers from independent components exhibiting basic functions and the extension to more sophisticated information processing schemes, highlighting the potential of synthetic biology strategies to support the rapid engineering of cellular behavior. Coupled with technologies that enable the de novo generation of new RNA sensor components, RNA devices allow researchers to construct various user-programmed information processing operations in living systems. The application of these molecular devices to developing new disease treatment strategies such as targeted molecular and cellular therapeutics will be discussed.

Unconventional hydrocarbon resources from low-permeability formation, i.e., tight sands and shales, are currently received great attention because of their potential to supply the entire world with sufficient energy for the decades to come. In the past few years, as a result of industry-wide R&D effort, progresses are being made towards commercial development of gas and oil from such unconventional resources. However, studies, understandings, and effective technologies needed for development of unconventional reservoirs are far behind the industry needs. Unconventional reservoir dynamics is characterized by highly nonlinear behavior of
multiphase flow in extremely low-permeability rock, coupled by many co-existing, processes, e.g., non-Darcy flow and rock-fluid interaction within tiny pores or microfractures. Quantitative characterization of unconventional reservoirs has been a significant scientific challenge currently. Because of complicated flow behavior, strong interaction between fluid and rock as well as multi-scaled heterogeneity, the traditional Darcy-law-and-REV-based model may not be applicable for describing flow phenomena in unconventional reservoirs. In this presentation, we will discuss a general mathematical model proposed for unconventional reservoir simulation. We will present a unified framework model to incorporate various nonlinear flow and transport processes using a multi-domain, multi-continuum concept to handle multi-scaled heterogeneity of unconventional formation. Specifically, we will use extended or modified Darcy law to include the following processes: (2) non-Newtonian behavior (i.e., threshold pressure gradient for flow to occur); (3) non-Darcy flow with inertial effects; (3) adsorption and other reaction effect; and (4) rock deformation. The proposed modeling methodology has been implemented into a general reservoir simulator and will be demonstrated for its application in analyzing well tests in fractured vuggy reservoirs, non-Darcy flow, and non-Newtonian flow in porous and fractured reservoirs.
