Abstract: This application provides vector retrieval methods, and apparatuses, and storage media. In an example, in response to a query vector, at least one compressed vector having a highest similarity with the query vector is obtained from a first-level storage resource. Classification decision-making is performed on each compressed vector based on a classification model to obtain at least one target compressed vector whose corresponding original vector is a candidate vector most similar to the query vector. At least one target original vector corresponding to the at least one target compressed vector is obtained from a second-level storage resource. At least one similarity between the query vector and the at least one target original vector is calculated. The at least one target original vector is sorted based on the similarity, based on which, a vector retrieval result corresponding to the query vector is determined.

Abstract: The invention offers a device and method for in-situ cutting soil in boreholes. The device comprises a base with an accommodation cavity, a cutting mechanism attached to the base, featuring a driven driving part within the cavity and a cutting part at its opposite end. A telescopic drive mechanism atop the base connects to the cutting mechanism, facilitating its extension relative to the base along its length. A rotating drive mechanism at the base's bottom includes an active driving part within the cavity, rotating the cutting mechanism around its length axis. This enables the cutting part to slice soil along a plane perpendicular to its length extension. The device enables borehole tests to achieve a flat test surface, enhancing accuracy and effectiveness.

Abstract: According to embodiments of the present disclosure, a method, apparatus, device and storage medium for information display are provided. The method comprises in response to a target multimedia content to be presented to a first user, determining whether the first user has a permission to view a clear version of the target multimedia content. If it is determined that the first user has no permission to view the clear version of the target multimedia content, displaying a blurred version of the target multimedia content; and displaying an interactive information item associated with the target multimedia content in a clear mode. In this way, the interactive information items associated with the multimedia content can be displayed while the blurred version of the multimedia content is displayed, so as to provide more rich and interesting information display.

Abstract: Provided is a processor that is used for limited purposes such as preprocessing of raw data and that has a small circuit scale and high program processing efficiency, wherein an instruction block includes a 2-bit opcode. The processor can move to a branch destination or perform an operation by using an immediate bit accompanying the instruction block, by assigning a branch flag or an immediate instruction determination bit corresponding to the opcode.

Abstract: A system is presented for non-line-of-sight localization between RF enabled devices. A transmitting node is configured to transmit an RF ranging signal at a first carrier frequency, where the RF ranging signal is modulated with a symbol. The reflecting node is configured to receive the RF ranging signal and further operates to convert the RF ranging signal to a second carrier frequency and retransmit the converted ranging signal while simultaneously receiving the RF ranging signal. The localizing node is configured to receive the converted ranging signal from the reflecting node. The localizing node operates to identify, in frequency domain, the symbol in the converted ranging signal and compute a distance between the reflecting node and the localizing node based in part on the identified symbol in the converted ranging signal. The transmitting node and the localizing node may be on the same or different devices.
