Abstract: The disclosure provides a light-emitting device and a displayer. Herein, the light-emitting device includes a substrate, a light-emitting chip, a first light-transmitting layer, a second light-transmitting layer and a nano coating. The light transmittance of the second light-transmitting layer is greater than the light transmittance of the first light-transmitting layer. A reference surface corresponding to the light-emitting chip is arranged above the substrate, and the reference surface is higher than the bottom surface of the light-emitting chip and not higher than the top surface of the light-emitting chip. The first light-transmitting layer covers the surface of the light-emitting chip below the reference surface, and the second light-transmitting layer covers the surface of the light-emitting chip above the reference surface. The nano coating covers the outer surface of the first light-transmitting layer, the outer surface of the second light-transmitting layer and the side surface of the substrate.

Abstract: Disclosed are an arced plate, a first fastener, and a second fastener. The arced plate can define a first arced aperture array and a second arced aperture array. When the arced plate, the first fastener, and the second fastener are used in combination, the fasteners can retain the arced plate as a truncated cone. Each fastener can include inserts configured to extend through, and thereby occupy minor apertures formed in the arced plate.

Abstract: A pet drinking bowl component includes a steel pipe, a copper head inlayed at one end of the steel pipe, a seal ring arranged in the copper head, and a steel ball moving in the steel pipe and blocked by the seal ring. The end of the steel pipe is provided with a groove-inlaying part. A ring-inlaying part is arranged at an end of the copper head. The groove-inlaying part and the ring-inlaying part are spliced through glue. A seal ring mounting part is arranged on the copper head. And inner diameter of the seal ring mounting part is reduced along a water outlet direction. An outer wall of the seal ring is adhered to the mounting part. The seal ring mounting part is close to half a height of the steel ball.

Abstract: The present disclosure relates to other garbage and kitchen garbage classification throwing technologies in the technical field of garbage classification, in particular to a garbage bag. The garbage bag comprises a bag body, wherein the bag body is of a hollow structure with an opening in the top, a pouring opening is formed in the bottom of the bag body, and the bag body is formed in a folding mode so that the bottom of the bag body is fixed to one side of the bag body. When garbage in the bag body needs to be poured out, a point-breaking line or glue is torn off, the bottom of the bag body is separated from one side of the bag body, and after the bottom of the bag body naturally droops, the garbage is poured downwards from the point-breaking line under the gravity of the garbage to be separated from the bag body.

Abstract: A computer-implemented method for correcting artifacts within CT images of a subject includes providing iteratively correcting a CT volumetric image with a high-contrast mask by overpainting the high-contrast mask within CT volumetric image set by evaluating a model function and updating the CT projections to reflect the overpainting using a gradient descent based on previous overpainted CT projections, back-projecting the corrected CT projections to produce a corrected volumetric image set, and comparing the corrected CT volumetric image set against a previous corrected CT volumetric image set until convergence. The original voxels overpainted by the high-contrast mask are re-inserted into the converged CT volumetric image to produce the final CT volumetric image set.

Abstract: In response to a map task distributed by a job tracker, a map task tracker executes the map task to generate a map output including version information. The map task tracker stores the generated map outputs. The map task tracker informs the job tracker of related information of the map output. In response to a reduce task distributed by the job tracker, the reduce task tracker acquires the map outputs for key names including given version information from the map task trackers, wherein the acquired map outputs include the map outputs with the given version information and historical map outputs with the version information prior to the given version information. The reduce task tracker executes the reduce task on the acquired map outputs.
