Abstract: A hemostasis and suturing conjoined dual-clamp capable of passing through a channel of a digestive endoscope and an operation method, the dual-clamp including a handle, a clamping assembly and a driving assembly. The clamping assembly includes a clamping holder and two clamping portions, and the driving assembly is detachably connected to the clamping assembly. A hemostasis and suturing conjoined dual-clamp capable of passing through a channel of a digestive endoscope and an operation method, two clamping arms of the dual-clamp are able to individually open, clamp and close, have a function of double-sided clamping and closing a large defective wound, and are able to be conveniently separated from the driving assembly, overcoming the defects that conventional hemostatic clamps can only perform one-sided clamping, thereby it is difficult to treat defective wounds that are large or in difficult operating sites.

Abstract: In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed views—further minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modelled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. Logos may be identified and used—or ignored—in product identification. A great variety of other features and arrangements are also detailed.

Abstract: The present disclosure relates to a method and apparatus for manufacturing a semiconductor sheet assembly. The method for manufacturing a semiconductor sheet assembly includes positioning a semiconductor sheet, and determining a first region to be grooved and a defect position in the first region; cutting and grooving the semiconductor sheet along the defect position in the first region; and splitting the semiconductor sheet that is cut and grooved.

Abstract: Systems and methods for enhancing the stability and efficiency of perovskite materials, and devices incorporating such perovskite materials. A method of making a perovskite layer includes mixing a perovskite solution with a silica shell precursor solution to produce a perovskite-silica precursor solution, and spin casting or drop casting the perovskite-silica precursor solution on a substrate to form a perovskite material or material layer, wherein the perovskite material or material layer includes a plurality of groups of one or more perovskite grains, each of said plurality of groups wrapped in a silica shell. The silica shell precursor solution may have a chemical structure of Rn—Si—(OR)4-n, where “R” is an alkyl, aryl, or organofunctional group, and “OR” is a methoxy, ethoxy, or acetoxy group.

Abstract: A nanometer plugging water-based drilling fluid and preparation method and use thereof are within this disclosure. The nanometer plugging water-based drilling fluid comprise a nanometer plugging agent. The nanometer plugging agent may be surface modified SiO2 powder with the surfactant. The surfactant may be sodium dodecyl benzene sulfonate and/or sodium dodecyl sulfate. The nanometer plugging water-based drilling fluid may perform effective anti-collapse of stratum and maintain the stability of stratum.

Abstract: The present disclosure relates generally to image signal processing, including encoding signals for image data or artwork. A color blend/print model is used to predict signal detectability and visibility as is printed on a particular substrate, which facilitates object grading prior to print runs.

Abstract: A method for calculating the quantity of goods based on weighing includes the following steps: Step 1, Weight Conversion; accurately convert the weighing reading to the corresponding weight value W; Step 2, Weight Scaling; that is, the conversion of weight units; Step 3, Zero Point Correction; calibrate the weight reading; Step 4, Tare; remove the weight of non-goods objects in the weight value; Step 5, Anti-Mutation Filtering; anti-mutation filtering on the weight value; Step 6, Quantity Conversion; convert the weight value after calibration and correction of steps 1 to 5 above into the approximate (rough) quantity of the goods; Step 7, Quantity Calibration; calibrate the rough quantity of the above-mentioned goods.

Abstract: A method for changing a member in a distributed system, includes requesting, by a first target node, a node address set from a management server, where the node address set includes first addresses of all nodes in the distributed system, sending, by the first target node, a join request to a master node in the distributed system when the node address set does not comprise a second address of the first target node, adding, by the master node, the second address to the node address set, and instructing all slave nodes in the distributed system to add the second address to a corresponding local member list.

Abstract: The invention discloses a method and system for obtaining an evaluation model and an evaluation method and system for the plugging performance of drilling fluid. The method for obtaining the evaluation model comprises: applying a confining pressure to a holding device where a preset fracture model is located, wherein a displacement differential pressure of two ends of the holding device is a preset displacement differential pressure; measuring a flow of standard measuring fluid flowing through the preset fracture model under different confining pressures, wherein the different confining pressures gradually increase according to a first preset rule; and controlling to stop increasing the confining pressure when the flow of the standard measuring fluid flowing through the preset fracture model reaches a preset flow so as to compress the preset fracture model into the evaluation model at a micro-nano level.
