Abstract: A comfortable, light weight device to properly position and elongate breast tissue for extended periods of time during radiotherapy and other medical procedures. In one embodiment, the breast fixation device is a generally cylindrical inflatable enclosure that wraps around the breast tissue. In another embodiment, the breast fixation device is composed of multiple rings that are placed around the breast tissue and inflated. In a further embodiment, the breast fixation device consists of multiple inflatable fingers which drape around the breast tissue and then squeeze the breast tissue into an elongated position as they are inflated.

Abstract: A multicolor electronic display is based on an array of luminescent semiconductor nanocrystals. Nanocrystals which emit tight of different colors are grouped into pixels. The nanocrystals are optically pumped to produce a multicolor display. Different sized nanocrystals are used to produce the different colors. A variety of pixel addressing systems can be used.

Abstract: One or more magnets are placed in a container (preferably on objects inside the container) and the magnetic field strength and vector direction are measured with a magnetometer from at least one location near the container to provide the container with a magnetic vector field tag and seal. The location(s) of the magnetometer relative to the container are also noted. If the position of any magnet inside the container changes, then the measured vector fields at the these locations also change, indicating that the tag has been removed, the seal has broken, and therefore that the container and objects inside may have been tampered with. A hollow wheel with magnets inside may also provide a similar magnetic vector field tag and seal. As the wheel turns, the magnets tumble randomly inside, removing the tag and breaking the seal.

Abstract: Sinusoidal voltammetry was employed to detect both purine and pyrimidine-based nucleic acids. Adenine and cytosine, representing these two classes of nucleic acids, could be detected with nanomolar detection limits at a copper electrode under these conditions, where the sensitivity for adenine was much higher than that for cytosine. Detection limits for purine-containing nucleotides (e.g., adenosine 5'-monophosphate (AMP), adenosine 5'-diphosphate (ADP), and adenosine 5'-triphosphate (ATP)) were on the order of 70-200 nM using this method. These detection limits are achieved for native nucleotides and are over two orders of magnitude lower than those found with UV absorbance detection. Pyrimidine-based nucleotides could also be detected with high sensitivity due to the presence of a sugar backbone which is electroactive at the copper surface.
