Abstract: A novel strategy for monitoring the location of a transgene in a mammal is disclosed. A sodium iodide symporter is genetically fused to either the N-terminus or C-terminus of the product of a transgene through a linker peptide which bears the recognition sequence of a host cell protease. Expression of the transgene confers the activity of the sodium iodide symporter (NIS)to a host cell which expresses the transgene. Subsequent administration of labeled iodine results in transport of the labeled iodine into the cell bearing the NIS, which can then be localized and measured using standard imaging techniques. The system is particularly useful for monitoring the location of therapeutic transgenes and tissue-specific distribution of the therapeutic gene product.

Abstract: Communication between a remote locator and a transponder is used to determine the relative position of the transponder. The transponder and locator each include a transmitter and a receiver. The locator transmits an inquiry in the form of a relatively powerful cyclically encoded signal with repetitive elements, uniquely associated with a target transponder. Periodically, each transponder correlates its coded ID against a possible inquiry signal, determining frequency, phase and framing in the process. Upon a match, the transponder transmits a synthesized response coherent with the received signal. The locator integrates multiple cyclical response elements, allowing low-power transmissions from the transponder. The locator correlates the integrated response, determines round-trip Doppler shift, time-of-flight, and then computes the distance and angle to the transponder. The transponder can be wearable, bionically implanted, or attached to, or embedded in, some object.

Abstract: The present invention provides a method and system for detecting a material in an object to be analyzed in a radiographic imaging system. The method includes providing wide-field illumination of an object with partially monochromatic x-ray radiation from a divergent source without restrictively collimating the x-ray radiation. The x-ray radiation scattered by the object outside of a predetermined range of angles defined about a characteristic angle is rejected. The characteristic angle is a scattering angle about which a material of the object coherently scatters the incident x-ray radiation. In addition, the method includes the step of detecting coherently-scattered radiation, which is the x-ray radiation diffracted by the object within the predetermined range of angles defined about the characteristic angle.

Abstract: An image is analyzed to locate an object appearing in the image. A contour of that object is extracted from the image and normalized. Based on the normalized contour, one or more summation invariant values are determined and compared to templates comprising one or more summation invariants for each of one or more target objects. The determined summation invariants for the extracted object are compared to summation invariants for the target objects. When the summation invariants for the extracted object sufficiently match the summation invariants determined from an image of a target object, the extracted object is recognized as that target object. The summation invariants can be semi-local summation invariants determined for each point along the normalized contour, based on a number of points neighboring that point on the normalized contour. The semi-local summation invariants are determined as a function of the x and y coordinates of those points.

Abstract: Projection views of the moving heart and stationary background tissues are acquired and processed to provide corresponding moving tissue projection views. An average image is reconstructed in a conventional manner and a moving tissue image is reconstructed using a highly constrained backprojection method and a composite image formed from selected moving tissue projection views. The average image is then combined with the moving tissue image. The method is disclosed in a cardiac gated MRI scan.

Abstract: A method and a system of determining a surface location defining an interface between an object to image and an antenna is provided. The method uses geometric principles and the fact that an impedance mismatch at the interface results in significant reflection. A propagation time from the surface to each antenna of a plurality of antennas is estimated. The propagation time locates the surface on a circle centered at each antenna and having a radius calculated using the propagation time. A tangent line connects the intersection of adjacent circles with the surface. The surface is estimated to be located at the tangent point where the circle and the shared tangent line between adjacent antennas intersect. Multiple tangent points may be averaged for each interior antenna. A curve is fit to the set of tangent points to provide an estimate of the surface location.

Abstract: Carbon nanotube Schottky barrier photovoltaic cells and methods and apparatus for making the cells are provided. The photovoltaic cells include at least one contact made from a first contact material, at least one contact made from a second contact material and a plurality of photoconducting carbon nanotubes bridging the contacts. A Schottky barrier is formed at the interface between the first contact material and the carbon nanotubes while at the interface between the second contact material and the carbon nanotubes, a Schottky barrier for the opposite carrier is formed, or a small, or no Schottky barrier is formed. It is the Schottky barrier asymmetry that allows the photo-excited electron-hole pairs to escape from the carbon nanotube device.

Abstract: The present invention features additions of nano-structures to interconnect conductor fine particles (spheres) to: (1) reduce thermal interface resistance by using thermal interposers that have high thermal conductivity nano-structures at their surfaces; (2) improve the anisotropic conductive adhesive interconnection conductivity with microcircuit contact pads; and (3) allow lower compression forces to be applied during the microcircuit fabrication processes which then results in reduced deflection or circuit damage. When pressure is applied during fabrication to spread and compress anisotropic conductive adhesive and the matrix of interconnect particles and circuit conductors, the nano-structures mesh and compress into a more uniform connection than current technology provides, thereby eliminating voids, moisture and other contaminants, increasing the contact surfaces for better electrical and thermal conduction.
