Network Seeding
This research studies the optimal seeding of a network of consumers who are potential adopters of a technology. This problem has a wide range of applications which include launching a network good, inducing network-based marketing, igniting collaboration in organizations, and stimulating R&D with local spillovers. I have two main results so far. The first result shows that when a firm is unawar...
متن کاملEnvironmental Interactions in the GFDL Hurricane Model for Hurricane Opal
Hurricane Opal (1995) crossed the Gulf of Mexico rapidly intensifying to a 130-kt storm, then fortunately weakening before landfall on the Florida panhandle. This intensification was underforecast by the National Hurricane Center. Forecast fields from the 1997 version of the Geophysical Fluid Dynamics Laboratory Hurricane Prediction System (GFDL model) for Hurricane Opal are used to diagnose th...
متن کاملEndothelial cell seeding.
Endothelial cell seeding is a technique that has developed over the past 15 years in response to the need for a high performance synthetic vascular graft.

متن کاملSelf-seeding in cancer.
Despite significant progress in our understanding and treatment of metastatic cancer, nearly all metastatic cancers are incurable. In this Review, we use breast cancer as a model to highlight the limitations and inconsistencies of our existing treatment paradigms for metastatic disease. In turn, we offer a new theory of metastasis, termed "self-seeding. " The self-seeding paradigm, well validat...
متن کاملAutomatic Stream Surface Seeding
The visualisation of 3D flow poses many challenges. Difficulties can stem from attempting to capture all flow features, the speed of computation, and spatial perception. Streamlines and stream surfaces are standard tools for visualising 3D flow. Although a variety of automatic seeding approaches have been proposed for streamlines, little work has been presented for stream surfaces. We present a...
