A system and method for image reconstruction is disclosed. The method divides iterative image reconstruction into two stages, in the image and Radon space, respectively. In the first stage, filtered back projection and adaptive filtering in the image space are combined to generate a refined reconstructed image of a sinogram residue. This reconstructed image represents an update direction in the image space. In the second stage, the update direction is transformed to the Radon space, and a step size is determined to minimize a difference between the sinogram residue and a Radon transform of the refined reconstructed image of the sinogram residue in the Radon space. These stages are repeated iteratively until the solution converges.

The invention provides polymer conjugates of opioid antagonists comprising a polymer, such as poly(ethylene glycol), covalently attached to an opioid antagonist. The linkage between the polymer and the opioid antagonist is preferably hydrolytically stable. The invention also includes a method of treating one or more side effects associated with the use of opioid analgesics, such as constipation, nausea, or pruritus, by administering a polymer conjugate of the invention.

A complex flow-path heat exchanger having U-shaped tube and cantilever combined coil, which can achieve, in this type heat exchanger, a simple construction, a complex flow of steam within the same one heat exchange shell body, a high heat exchange efficiency, and a low energy loss. The technical gift of the present invention is that, after entering into the heat exchanger, steam firstly effects heat exchange on the U-shaped tube flow path shell side to be cooled and condensed, thereafter entering into flow path tube side of the cantilever combined coil, which are disposed within the same one shell, for a secondary heat exchange, and subsequently flowing out of the heat exchanger after being subcooled. Such steam-water heat exchanger having a complex flow path are advantageous in a small steam flow resistance of the U-shaped tube flow path shell side; a higher condensate water flow velocity in the cantilever combined coils flow path tube; a high heat exchange coefficient; good coordination of the temperature difference fields of the hot and cold fluids in the heat exchanger; and a high heat exchange efficiency. Therefore, the present heat exchanger can be a new generation product relative to the currently-used conventional low-temperature, low-pressure and corrosion-free heat exchangers.

A semiconductor die and a process for fabricating the semiconductor die are disclosed. The semiconductor die has a substrate and a silicon carbide (SiC) epitaxial structure on the substrate. The SiC epitaxial structure includes at least a first N-type SiC layer, at least a first P-type SiC layer, and carbon vacancy reduction material, which has been implanted into a surface of the SiC epitaxial structure. Further, the SiC epitaxial structure has been annealed to mobilize the carbon vacancy reduction material to diffuse carbon atoms substantially throughout the SiC epitaxial structure, thereby increasing an average carrier lifetime in the SiC epitaxial structure.

A bipolar junction transistor (BJT), which includes a collector layer, a base layer on the collector layer, an emitter layer on the base layer, and a recess region embedded in the collector layer, is disclosed. A base-collector plane is between the base layer and the collector layer. The recess region is may be below the base-collector plane. Further, the recess region and the base layer are a first type of semiconductor material. By embedding the recess region in the collector layer, the recess region and the collector layer form a first P-N junction, which may provide a point of avalanche for the BJT. Further, the collector layer and the base layer form a second P-N junction. By separating the point of avalanche from the second P-N junction, the BJT may avalanche robustly, thereby reducing the likelihood of avalanche induced failures, particularly in silicon carbide (SiC) BJTs.
