Abstract: Processing historical browsing content with an electronic device which can generate a first user operation page of a target application; in response to a historical reference operation triggered via the first user operation page, generate a browsing record page including a historical content area, one historical content area corresponding to one content type, and each historical content area including first content description information; and in response to a presenting operation for first content description information selected from the historical content area, generate target historical browsing content corresponding to the selected first content description information, and therefore the first content description information of the historical browsing content under each content type may be provided in a centralized mode through a browsing record page, so that content desired to be browsed again may be found in a short time, improving the search efficiency for the historical browsing content.

Abstract: The present disclosure relates to a blockchain-based trusted transaction method for a data product, including identity authentication based on a blockchain, creation of an identity code for a data asset, transaction of data, uploading of an enterprise authorization letter to the blockchain, and generation of a data right-confirmation letter. The present disclosure can build a trusted power-system data-transaction platform, help data confirm rights, promote circulation, transaction, and sharing of data, improve data authenticity, and realize efficient, stable, safe and reliable data assetization.

Abstract: A permanent magnet machine includes a stator configured to generate a stator magnetic field when excited with alternating currents and extends along a longitudinal axis with an inner surface defining a cavity, a rotor disposed inside said cavity and configured to rotate about the longitudinal axis, and a plurality of permanent magnets for generating a magnetic field, which interacts with the stator magnetic field to produce a torque. At least one of the plurality of permanent magnets has a light rare earth material including neodymium and praseodymium, and less than about 5 weight percent of a heavy rare earth material, wherein the weight percentage of neodymium is larger than the weight percentage of praseodymium but smaller than three times of the weight percentage of praseodymium.

Abstract: A radiation detector includes a semiconductor crystal having a first surface and a second surface opposite to the first surface, a first electrode electrically coupled with the first surface of the semiconductor crystal to allow current to flow between the first electrode and the crystal, and an insulating layer on the first surface and between the semiconductor crystal and the first electrode so as to create a partially transmissive electrical barrier between the first electrode and the crystal. The insulating layer has a thickness ranging from about 50 nanometers to about 500 nanometers.

Abstract: This invention provides a structure of load-balancing packet switches with minimum buffers complexity and its concomitant methodology. It abandons the VOQ between the first stage and the second stage fabrics, which has no problems of queue delay and packets out-of-sequence. Therefore, this invention solves the packets out-of-sequence problem in load-balancing Birkhoff-von Neumann switching structure and improves the end-to-end throughput. Moreover, it greatly reduces the buffer complexity to O(N).
