Abstract: This application provides a network acceleration method, an electronic device, and a readable storage medium, and relates to the field of network communication technologies. Different data flows in an electronic device correspond to different flow quality evaluation conditions. When a flow quality parameter of any data flow meets a flow quality evaluation condition corresponding to the data flow, the electronic device switches the data flow from a current network interface card to another network interface card for transmission, thereby implementing network acceleration. The flow quality parameter includes at least one of the following parameters: a latency, a rate, a packet loss rate, a retransmission rate, or whether a packet response times out. Because corresponding flow quality evaluation conditions are respectively set for different data flows, different network acceleration time points can be obtained for flow quality of the data flows, thereby avoiding a freezing phenomenon.

Abstract: Skew handling techniques are provided in parallel execution for even load balancing and scaling. In a compile-time solution, a dynamic sampling query is issued to detect partition skew. The compile-time solution determines the number of skewed partitions and uses a hybrid distribution scheme where skewed partitions use a random distribution and non-skewed partitions use the original server mapping. In a runtime solution, producer server processes create partition mapping vectors that contain partition mapping information. Each producer server process sends its partition mapping vector to the query coordinator (QC). The QC receives the partition mapping vectors from the producer server processes, merges the vectors, and determines a skew result based on the merged mapping vectors and sends the skew result to the producer server processes. The producer server process can alter distribution of skewed partitions based on the skew result.

Abstract: A network acceleration method, an electronic device, and a storage medium, which relate to the field of network communication technologies, so as to reduce freezing phenomena during video playback. The method includes: when an electronic device runs an application that does not include a peer-to-peer (P2P) flow, a data flow that requires high network quality may be switched to another network with better quality when quality of a currently used network is poor. When the electronic device runs an application that includes a P2P flow, and when a currently used network is poor, because it is difficult to switch the P2P flow to another network with better quality, all data flows of the electronic device may be switched to the another network, thereby reducing video freezing phenomena caused by a difficulty of switching the P2P flow to the another network with better quality.

Abstract: Techniques are described for a multiple-phase process that uses machine learning (ML) models to produce a texturized version of an input image. During a first phase, using a pix2pix-based ML model, an automatically-generated image that depicts structured texture is generated based on an input image that visually identifies a plurality of image areas for the structured texture. During a second phase, a neural style transfer-based ML model is used to apply the style of a style image (e.g., a target image from the training dataset of the pix2pix-based ML model) to the texture image generated at the first phase (the content image) to produce a modified texture image. According to an embodiment, during a third phase, the generated texture image produced at the first phase and the modified texture image produced at the second phase are combined to produce a structured texture image with a moderated amount of detail.

Abstract: According to implementations of the subject matter described herein, a solution is provided for pirated copy tracing based on a third party. In the solution, a report on a pirated copy of a digital content is received from a third party, wherein the report comprises first secret information for characterizing a first identification, time information and tracing information of the pirated copy. Subsequently, a request for verifying the report is received to determine whether the report is valid. When the report is determined as valid, a licensee associated with the report is marked as a first status to indicate that the pirated copy might be leaked by the licensee. Therefore, the pirated copy may be effectively traced based on third parties. The tracing information in the report can be hidden, and other third parties can therefore be prevented from using the tracing information for duplicate reports.

Abstract: The present disclosure provides a rigid self-supporting MXene separation membrane and a preparation method and use thereof, belonging to the technical field of membranes. In the present disclosure, a MXene material is mixed with an aluminum salt powder to conduct one-step membrane formation by hot-pressing. The pressure forms the powder into a membrane and imparts rigidity, enabling a self-supporting structure; the heating breaks an ionic bond of an inorganic metal salt to reach a molten ionic state, and free metal cations react with active oxygen-containing functional groups on the surface of the MXene to form new chemical bonds (such as an Al—O bond); such a chemical bond has higher energy, achieving a desirable anti-swelling effect to improve the membrane stability. The separation membrane further has excellent conductivity and hydrophilicity.

Abstract: A key-value store is provided, implementing multiple-tiered sorted data structures in memory and storage, including concurrent write buffers in memory, and page-level consolidation of updates on storage, where pages are trivially translated in physical-to-virtual address mapping. The key-value store is built on an indexed sorted data structure on storage, occupying much less storage space and incurring much less disk activity in consolidating updates than a conventional log-structured merge tree organized into files. Concurrent write buffers operate concurrently and independently so that data is committed from memory to storage in an efficient manner, while maintaining chronological sequence of delta pages. Trivial mapping allows mappings of a number of physical pages to be omitted, enabling page mapping tables to occupy less storage space, and simplifying processing workload of read operation retrievals from storage.

The current server list may be updated through replacing the at least one current server with the at least one candidate server. Data traffic to be sent may be allocated based on the updated current server list, so as to achieving load balancing in the server cluster.
