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.

Abstract: A Visual Simultaneous Localization and Mapping (V-SLAM) system for a mobile host, e.g., a vehicle, includes a sensor suite and controller. The sensor suite collects raw input data used to estimate parameters of the host. The controller includes a processor and a computer storage medium (“memory”) containing computer-readable instructions. Execution of the instructions by the processor causes the controller to receive the input data, use the input data to estimate poses of the host and calculate three dimensional (3D) coordinates of feature map points, and identify outliers in the feature map points using a predetermined linear algebra property, e.g., condition numbers. The controller also dynamically filters out the outliers using dynamic covariance scaling to generate a filtered feature map point set and transmits the set to a navigation system of the mobile host.

Abstract: A perception data geometry calibration system calibrates perception data geometry captured by one or more vehicles located within a predefined geographical area. In one embodiment, the perception data geometry system includes one or more central computers that receive local map data representing the predefined geographical area from a particular vehicle and corresponding high-definition map data over a communication network. The local map data includes a plurality of perception data geometry features that define objects within an environment surrounding the particular vehicle. The one or more central computers determine a unique calibrated scaling ratio for each road segment that is part of a vehicle trajectory based on one or more non-linear optimization algorithms by minimizing a cost function between road-segment points that represent a particular perception data geometry feature based on the local map data with corresponding road-segment points that are based on the high-definition map data.

Abstract: A transmission line can include a first conductive line, a second conductive line, a signal line disposed between the first conductive line and the second conductive line, with a first gap between the signal line and the first conductive line, and a second gap between the signal line and the second conductive line. A first shield can be disposed directly over a portion of the first gap, and a second shield can be disposed directly over a portion of the second gap. A slot can separate the first shield from the second shield. The transmission line can be a coplanar waveguide.
