    摘要： An integrated microfluidic device and its usage are provided. The microfluidic device comprises an upper layer (1) and a lower layer (2), wherein the lower layer (2) is bound to the upper layer (1). The upper layer (1) comprises a micro-channel (3) and the lower layer (2) comprises a micro-well (7) array. The micro-channel (3) is in fluidic connection with the micro-well (7) array, and the height of the micro-channel (3) is greater than the diameter of the oocyte (4) flowing through the micro-channel (3). The integrated microfluidic device has many advantages including low cost, high integration, and convenient operation, and has application prospects in reproductive medicine and the research of fertilization and embryo early development.

    摘要： A security device for mounting over the neck of a bottle having an exterior lip has outer cap structure including an annular housing portion (16) for location about the neck of a bottle and an end cap portion (18) at one end of the annular housing portion. A claw member (14) is slidably mounted to the outer cap structure for movement in a direction parallel to a longitudinal axis of the annular housing portion between operative and inoperative positions. A latch mechanism (60) releasably secures the claw member in the operative position. The claw member has a plurality of resiliently deformable elongate claws (52a, 52b) for engagement with the neck of a bottle to which the device is mounted when the claw member is in the operative position. The claw member comprises at least two sets of claws (52a, 52b) of different lengths. The latch mechanism (60) may be a magnetically-releasable latch enabling the device to be removed using a magnetic key. The device may incorporate a RF or RFID tag.

    摘要： A method for automatic vessel wall thickness measurement at any point along the perimeter of either luminal or outer vessel wall boundaries. The method employs both Delaunay triangulation and multiresolution tiling. The MaxMin angle property of the Delaunay triangulation is used to define the minimum energy function to calculate thickness. Multiresolution tiling is employed to enable the MaxMin angle lemma to be determined. The triangulation MaxMin angle lemma enables a minimal energy function to be defined based on triangulation angles, providing a stable and consistent geometrical computation. Additional morphological indexes can be assessed to achieve comprehensive quantification of vascular morphology. For example, based on the wall thickness, a set of vascular shape descriptors can be developed to distinguish different types of plaque morphology at different parts of a vessel wall.
