Abstract: A radar system for generating a radar image of a scene. Receive radar measurements of reflectivity of each point in the scene measured by receivers. Solve a radar image recovery (RIR) problem using stored data to produce the radar image. By connecting the radar measurements to a shift of a reflection field with a receiver shift. The receiver shift defines an error between stored receiver positions and actual receivers positions, the reflection field is generated by reflecting the transmitted field from the scene in accordance with the reflectivity of each point in the scene. Connecting the reflection field to a shift of an incident field with a transmitter shift. The transmitter shift defines an error between stored transmitter positions and actual transmitters positions. Solve as a multilinear problem of joint estimation of the reflectivity of each point in the scene, the receiver shift, and the transmitter shift.

Abstract: The invention provides cell-adherent polymeric coatings for articles, the coating including a synthetic, non-biodegradable polymer having a plurality of pendent amine groups, wherein the polymer is covalently immobilized on the article via latent reactive groups. The invention also provides methods for the long-term attachment of cells using the polymeric coatings.

Abstract: The invention provides cell-adherent polymeric coatings for articles having a nanofibrillar structure. The coatings include a synthetic, non-biodegradable polymer having at least one pendent amine group, wherein the polymer is covalently immobilized on the article via latent reactive groups. The invention also provides methods for the long term culturing of cells using the polymer coated nanofibrillar structures. The polymer coated nanofibrillar structures of the invention have been found to be particularly useful for the growth and differentiation of cells, including neural precursors.
