Abstract: A tool box and a tool kit are provided. The tool box includes a box body and a cover body. A first side surface and a second side surface of the box body are provided with communicated openings, the box body is provided with a control component, each control component is provided with a first suction component. The cover body covers the opening, and is provided with a second suction component. When the cover body covers the opening, the corresponding second suction component and first suction component are sucked. The cover body is rotationally connected to the box body, the rotational connection part between the cover body and the box body is provided with an elastic component. When the control component is pressed or pushed, the corresponding second suction component and first suction component are separated, the elastic component bounces the cover body to open the box body.

Abstract: A method for correcting photoelectric logging measurements includes acquiring a photoelectric factor image including photoelectric factor measurements in at least first and second azimuthal sectors in a borehole. The photo electric factor image is processed using a system of equations to compute a photoelectric factor of a formation through which the borehole penetrates and photoelectric factor of the drilling fluid in the borehole.

Abstract: A system for fusing two or more versions of map data together includes one or more central computers that receive road network data representing a road network for a predefined geofenced area. The central computers receive road network data that includes a discrete random curve that represents lane markings. The discrete random curve includes a plurality of state vectors that are each defined by a respective location and tangent angle. The central computers estimate the position for the state vectors of the discrete random curve based on a signed distance and the tangent angle by minimizing a spatial Kalman filter cost function and execute a Kalman smoothening function to estimate the position and the tangent angle for the state vectors that are part of the discrete random curve, where the state vectors each represent a map point of the fused map data.

Abstract: In an example, a memory controller is configured to: check whether a logical block address corresponding to a host read command is maintained in a write buffer; determine a level of an amount of drift corresponding to the logical block address if the logical block address is not maintained in the write buffer, where different levels of the amount of drift correspond to different read voltages; and send a read command to a non-volatile memory device according to the level of the amount of drift corresponding to the logical block address. At least two of the processes of checking whether the logical block address is maintained, determining the level of the amount of drift, or sending the read command are performed in parallel.

Abstract: A B-cell specific octamer-binding protein 1 super-enhancer ribonucleic acid (BOB1-seRNA) and an application thereof are provided. The nucleotide sequence of the BOB1-seRNA is shown in SEQ ID NO: 1. Through experiments, it further confirms that the BOB1-seRNA is downregulated in patients with coronary heart disease and can be used in preparation of a product for diagnosing or predicting the coronary heart disease. The use of this molecular marker can be used for early diagnosis of the coronary heart disease, which is rapid and effective. It is not only of great significance for early treatment of the coronary heart disease and saving medical costs, but also provides therapeutic targets and important basis for clinical applications such as gene therapy and drug therapy.

Abstract: The present application provides a method and system for inferring an electron temperature from a hollow cathode plume color, applicable to diagnosis and inference of the electron temperature distribution of the hollow cathode under in-orbit or other vacuum environments. The method includes extraction of plume color data of the hollow cathode, two-dimensional processing of the plume color data, establishment of a correlation database between gridded colors and electron temperatures, and inference of the electron temperature distribution using the gridded colors. The inferred data of the electron temperature obtained in the present application exhibits trends consistent with measurement data obtained using a Langmuir probe, with diagnostic deviations within 30%. Based on the present application, researchers can directly leverage hollow cathode plume images to perform rapid, non-contact diagnosis of the electron temperature distribution characteristics.
