    摘要： A method for detecting blood vessel bifurcations in digital medical images includes inflating a sphere from a first center point inside a segmented blood vessel until a surface of the sphere intersects a surface of the blood vessel, searching within the inflated sphere for a second center point that has a sphere intersecting a surface of the blood with a maximum radius, assigning all voxels of the maximal radius sphere to a root node of a shape-tree, increasing the radius of the maximal radius sphere and computing a voxel difference set with respect to the previous maximal radius sphere, computing one or more connected components Cm in the voxel difference set, assigning voxels of each connected components to a different child node of the shape tree, connecting each child node with the root node, and calculating features from the shape tree for training a classifier to detect blood vessel bifurcations.

    摘要： A method for segmenting image data includes creating a plurality of marching regions within the medical image data. Region-wise segmentation is performed on the plurality of marching regions. Region-wise segmentation may include a normalized cut performed on a graph wherein each marching region represents a node. Region-wise segmentation may also include or may alternatively include a min cut performed on a graph wherein each marching region represents a node. Voxel-wise segmentation is performed on a subset of the plurality of marching regions.

    摘要： Provided are a flexible and transparent carbon nano tube (CNT) thin film transistor using a degradable polymer substrate, and a display adapting the CNT thin film transistor. The polymer substrate is formed of a polymer material that is naturally degraded, and a CNT channel, where a semiconductive CNT is dispersed on a transparent organic material, is prepared on the polymer substrate. Source and drain electrodes, where a conductive CNT is ejected on a transparent organic material, are connected to both sides of the CNT channel. A gate, where a conductive CNT is dispersed on a transparent organic material, is disposed on or below the CNT channel, and a gate insulation layer including a transparent organic material is disposed between the CNT channel and the gate.

    摘要： A sealing assembly includes a component, a polyvinyl chloride foam gasket, a double sided acrylic tape, and a butyl tape. The component has a wall, an interior space defined by the wall, and an opening extending through the wall into the interior space. The wall has a rib extending therefrom and surrounding the opening. The gasket has a base, two sides, first and second ends, a length, and a groove formed therein and defined by the two sides and the base of the gasket. The groove extends along the length of the gasket. The gasket is positioned along the rib such that the rib extends into the groove, the gasket extends around the opening and the first and second ends of the gasket abut.Accordingly, upon entry of the amendment to the abstract, the new abstract reads:A sealing assembly includes a component, a polyvinyl chloride foam gasket, a double sided acrylic tape, and a butyl tape.
