Abstract: A biological treatment of sewage device and method for realizing advanced nitrogen removal of domestic sewage by half partical nitrification-anammox coupled with sulfur autotrophic denitrification. The device includes a raw water tank, a half partical nitrification reactor, a regulating water tank and an anammox coupled denitrification reactor. The domestic sewage enters the half partical nitrification reactor, a mass concentration ratio of NO2?—N to NH4+—N in effluent water is 1-1.32 through real-time control, and then the effluent water enters the intermediate water tank. After it enters the upflow anammox coupled with autotrophic denitrification granular sludge reactor, the synergistic reaction of anammox and sulfur autotrophic denitrification in the reactor achieves the nitrogen removal.

Abstract: Disclosed are a method and device for realizing advanced nitrogen removal of mature landfill leachate and sludge reduction by using sludge fermentation products as carbon source, belonging to the field of biological treatment of sludge of high ammonia nitrogen wastewater.

Abstract: Methods, systems, and media for training deep neural networks for cross-domain few-shot classification are described. The methods comprise an encoder and a decoder of a deep neural network. The training of the autoencoder comprises two training stages. For each iteration in the first training stage, a batch of data samples from the source dataset are sampled and fed to the encoder to generate a plurality of source feature maps, then determining a first training stage loss, which updates the autoencoder's parameters. For each iteration in the second training stage, the novel dataset is split into a support set and a query set. The support set is fed to the encoder to determine a prototype for each class label. The query set is also fed to the encoder to calculate a query set metric classification loss. The query set metric classification loss updates the autoencoder's parameters.

Abstract: This application discloses a database system update method, applied to a database including a first node, a second node, and a shared storage device. The method includes: The first node sends a first instruction to the second node, where the first instruction is used to request storage location information of first data in the shared storage device, and the first data is data transferred by the second node to the first node for processing; and the first node obtains first information sent by the second node, and obtains mapping information from the shared storage device based on the first information, where the mapping information indicates a storage location of the first data in the shared storage device. The method is used to improve update efficiency of the database system, and ensure that different nodes can simultaneously process different data in a shared storage device.

The method for target identification comprises: acquiring scanning data of a subject, wherein the scanning data comprise the data acquired from magnetic resonance imaging of the brain of the subject; determining at least two regions of interest of the subject based on the scanning data; determining at least one abnormal region of interest in the at least two regions of interest in accordance with a predetermined anomaly detection rule; determining a target based on the at least one abnormal region of interest.

Abstract: The disclosure relates to techniques for saturation band MRI scanning. The techniques include obtaining the position of a saturation band of the saturation band MRI, obtaining the position of the region of interest to be imaged, taking the direction from the saturation band to the region of interest as a first direction, determining the direction of the slice selection gradient, and starting saturation band MRI scanning.

Abstract: A method for replaying a log on a data node, a data node, and a database system are described. The method is used to improve a log replay speed, and includes: the data node obtaining a plurality of logs, wherein the plurality of logs includes at least one transaction commit log and at least one page operation log; and a first thread of a plurality of threads replaying the at least one page operation log, and a same second thread replaying all page operation logs including an operation on a same page. As such, log replay progress does not need to be synchronized between threads. A process in which the first thread replays the transaction commit log is independent of a process in which at least one second thread replays the at least one page operation log.

Abstract: The present invention relates to a driving structure for use in an optical actuator, including: a first driving part, which is suitable for mounting a lens and driving the lens to move transversely in the x-axis and y-axis directions; and a second driving part, which is suitable for driving a photosensitive chip to move transversely in the x-axis and y-axis directions, where the lens and the photosensitive chip are configured to be driven simultaneously and to move in opposite directions. Also provided in the present invention are a corresponding photographing method, an optically stabilizing photographing module, and a corresponding assembly method. The present application increases the stabilization travel and the stabilization response speed of the photographing module.
