Abstract: This application provides a vehicle, and an integrated driving and braking control apparatus and method for a vehicle. The vehicle includes a first electric motor brake and a second electric motor brake that are disposed on a first side of the vehicle, a drive system that is disposed on a second side of the vehicle and has an energy regeneration function, and a control apparatus. The control apparatus is configured to control a left wheel of first side wheels of the vehicle to be braked by only the first electric motor brake and a right wheel of the first side wheels of the vehicle to be braked by only the second electric motor brake. The control apparatus is further configured to control a left wheel and a right wheel of second side wheels of the vehicle to be braked by only the drive system.

Abstract: A powertrain and a vehicle. The powertrain includes an enclosure, a separator, a motor, a first liquid return channel, and a second liquid return channel. The separator separates an interior of the enclosure into a first cavity and a second cavity. The motor is located in the first cavity. The first liquid return channel is located on an outer side of the enclosure and communicates with the first cavity and the second cavity. The second liquid return channel is located on the outer side of the enclosure and communicates with the first cavity and the second cavity. In the embodiments, with two liquid return channels provided, a liquid return requirement can be met when the powertrain is installed or disposed at any angle or used on a slope, improving adaptability and safety of the powertrain.

Abstract: This application provides a braking system, a control apparatus, and an electric vehicle. The braking system includes a controller and four actuators. Each actuator includes a brake disc. The braking system is configured to adjust, based on temperatures of four brake discs, braking force output by the four actuators. The controller is configured to control an actuator corresponding to a brake disc with a too high temperature to reduce braking force output, or is configured to control an actuator corresponding to a brake disc with a too low temperature to increase braking force output.

Abstract: Described are devices and associated methods of producing extracellular matrix (ECM) sheet devices with strengthened mechanical properties due to the selective retention of muscle tissue layers during processing.

Abstract: A system for converting a machine learning algorithm includes: a programmatic interface layer configured to construct a data-flow diagram of an original machine learning algorithm based on a preset data flow generation tool; an operator placement and evaluation module configured to calculate placement costs of each operator in the data-flow diagram when the operator is executed by different participants; a data-flow diagram dividing and scheduling module configured to divide the data-flow diagram into multiple sub-diagrams according to the placement costs, and schedule each of the sub-diagrams to a target participant for execution; and a compilation and execution layer configured to compile the sub-diagrams into a new data-flow diagram based on a greedy algorithm strategy, and generate an instruction for each operator in the new data-flow diagram to obtain a distributed privacy protection machine learning algorithm.

Abstract: The present disclosure provides a method and an apparatus for publishing product information. The present disclosure provides a method for publishing product information. Based on a stored search click log of buyers, correlation information between inquiry words and categories in the search click log is calculated. A keyword input by the seller is matched to the inquiry words. The keyword may be a word or a phrase that includes one or more words. If the keyword is matched to at least one inquiry word, at least one category corresponding to the matched inquiry word is obtained based on the correlation information. The product information is stored under one or more categories of the obtained categories. The present techniques improve the accuracy rate of recommended categories to the seller and the return rate of the published product information.

Abstract: The present disclosure provides techniques to rank search results. The techniques may include acquiring a set of primitive characteristics and extracting effective characteristics from the set of primitive characteristics based on historical transaction data. The effective characteristics include characteristics that can have an influence on ranking of search results. The techniques may also include determining an initial weight of each of the effective characteristics based on the historical transaction data, and training the initial weight using the historical transaction data and a predetermined training model to obtain a final weight. Based on the final weight, the search results may be ranked. In some aspects, the techniques may also optimize the ranking to ensure the objectivity and accuracy of ranking results.
