Abstract: A short-flow nickel-cobalt-manganese co-extraction process for laterite nickel ore hydrometallurgy falls within the technical field of hydrometallurgy. The process includes the following steps: co-extracting an iron-aluminum removal leaching solution of the laterite nickel ore by using an organic acid extraction system to obtain an enriched nickel-cobalt-manganese solution; extracting impurities from the enriched nickel-cobalt-manganese solution by using a P204 extraction system to obtain a high-purity nickel-cobalt-manganese solution. The co-extraction process of the disclosure simplifies the current hydrometallurgical process flow for extracting nickel-cobalt-manganese from the laterite nickel ore, greatly reduces the acid, alkali, and extractant usage, energy consumption, and water consumption in the extraction process, and reduces the cost of nickel-cobalt-manganese extraction, which is of great significance for the industrial production of ternary nickel-cobalt-manganese raw materials.

Abstract: In various examples, a generalizable mobility model can receive a state and identifier of a robot, and generate an action for the robot based on the state and the identifier. The state can identify a position, environment, and navigation goal of the robot while the identifier can indicate a type of the robot. The generalizable mobility model can use the identifier to generate an action for the robot to reach the navigation goal from its position based on the type of the robot, such as a humanoid, quadruped, or wheeled robot. The generalizable mobility model can be a distilled combination of multiple robot type-specific models, and can use the identifier to mimic type-specific actions output by the multiple robot type-specific models to transmit to the robot to move the robot.

Abstract: The present invention provides a combination therapy of a nitrone compound or a pharmaceutically acceptable salt thereof with a SGLT-2 inhibitor. Research found that the nitrone compounds TBN and TN-2, when used in combination with a SGLT-2 inhibitor, can synergistically lower blood sugar and also reduce the 24-hour urinary microalbumin and urinary albumin creatinine ratio in db/db mice, demonstrating a protective effect on the kidneys. The inventor also unexpectedly discovered that the combination of the nitrone compound with the SGLT-2 inhibitor can reduce the risk of urinary and reproductive tract infections caused by SGLT-2 inhibitors.

Abstract: In various examples, a single generalizable mobility model can be applied to a variety of robot types. Actions output by the generalizable mobility model can be based on actions generated using imitation learning, and the actions can be refined per type of robot using residual reinforcement learning. A type-specific model can be updated per type of robot using residual reinforcement learning, and can be combined and distilled into the single generalizable model. Actions output by the type-specific model can be combined with actions generated using imitation learning, and results of the action on a simulated robot can update weights of one layer of the type-specific model. By building upon an imitation learning model and refining each type-specific model using residual reinforcement learning, the generalizable mobility model can improve data and time efficiency compared to continuous multi-type training while also avoiding joint multi-type training complexities.

Abstract: This disclosure provides methods, components, devices and systems for hybrid constructions of a polarization-adjusted convolutional (PAC) code. Some aspects more specifically relate to mechanisms according to which wireless communication devices may encode and/or decode wireless communications in accordance with a hybrid construction of a PAC code. Such a hybrid construction of a PAC code may be a weighted Gaussian approximation (GA)- and Reed-Muller (RM)-based construction of a PAC code. In some implementations, the hybrid construction may be associated with weighted sums of GA-based sub-channel polarization weights and RM-based sub-channel polarization weights. In some other implementations, the hybrid construction may be associated with weighted sums of indexes of a GA-based sequence and indexes of an RM-based sequence.
