Abstract: This application relates to an information exchange method and a related apparatus. The method includes: A resource-limited node (for example, a STA) requests to enable an AI-assisted rate adaptation function, and after agreeing to the request, a node with a more powerful function (for example, an AP) sends, to the STA, related information of a neural network (such as a structure, a parameter, an input, and an output of the neural network) that has been trained, so that the STA determines the neural network based on the related information, and performs inference and decision-making based on data observed by the STA, to obtain a rate adaptation decision result. According to embodiments of this application, a basis can be provided for the resource-limited node to implement AI-assisted rate adaptation, and further, performance can be improved.

Abstract: The present disclosure provides an intracranial artery stenosis detection method and system. The present disclosure obtains artery stenosis detection results based on a first maximum intensity projection (MIP) image and a second MIP image obtained by preprocessing a medical image by adopting a detection model based on an adaptive triplet attention module and generates an auxiliary report and visualization results according to target category information in the artery stenosis detection results. Therefore, the problem that existing manual interpretation methods are easily affected by the subjective experience of doctors and are time-consuming and laborious can be solved, thus improving accuracy and efficiency of intracranial artery stenosis detection.

Abstract: In order to ingest data from an arbitrary source in a set of sources, a computer system accesses predefined configuration instructions. Then, the computer system generates a dynamic data-ingestion pipeline that is compatible with a Hadoop file system based on the predefined configuration instructions. This dynamic data-ingestion pipeline includes a modular arrangement of operators from a set of operators that includes: an extraction operator for extracting the data of interest from the source, a converter operator for transforming the data, and a quality-checker operator for checking the transformed data. Moreover, the computer system receives the data from the source. Next, the computer system processes the data using the dynamic data-ingestion pipeline as the data is received without storing the data in memory for the purpose of subsequent ingestion processing.

Abstract: A process for preparing a catalytic cracking catalyst, which process comprises: a molecular sieve is introduced into a gas-phase ultra-stabilization reactor, the molecular sieve is moved without the conveying of carrier gas from a molecular sieve inlet of the gas-phase ultra-stabilization reactor to a molecular sieve outlet of the gas-phase ultra-stabilization reactor, and the molecular sieve is contacted and reacted with a gaseous SiCl4 in the gas-phase ultra-stabilization reactor, the molecular sieve resulting from the contacting and the reacting is optionally washed, then mixed with a matrix and water into slurry, and shaped into particles.

Abstract: The present invention discloses a method, an apparatus and a computer program for resource contention in device-to-device communication links. The method partitions the time-frequency radio resource grid with a resource block set forming the resource unit in the grid, for all available, used and unusable frequency bands around a given virtual central frequency. Each resource block set is partitioned into a common control channel and a data channel. With a given procedure of control data transmission between transmitting and receiving user terminals, the resources are competed and shared. Frequency shifting with short distance frequency change or frequency transference with a larger frequency hopping into a free radio resource is available. The competition procedure is done in order to fairly share the frequency bands as a function of time between different device-to-device communication links in a localized manner.

The method includes obtaining related information for interfering cellular user equipment in the hybrid network, reporting the related information for the interfering cellular user equipment to an evolved Node B (eNB), receiving a list of component carriers and competition related information for the component carriers, and selecting one or more proper component carriers from the list of component carriers according to certain rules.

Abstract: A method for tenant placement in a multi-tenant system is shown that includes creating a weighted graph of tenants and sharing relationships between tenants, where a weight for each tenant and each sharing relationship represents an associated degree of resource consumption; and adding one or more tenants to a database using a processor based on said weighted graph and a database capacity, such that the combined weight of the added tenants and the sharing relationships belonging to the added tenants are within the database capacity. If a tenant cannot be added to the database without exceeding the database capacity, a new database is created and the one or more tenants are added to the new database, subject to a new database capacity. The adding and creating steps are repeated until all tenants have been added to a database.

Abstract: Methods for generating a data fetching plan in a multi-tenant system include placing tenants in consecutively allocated databases according to a weighted graph of tenants and sharing relationships between tenants, where at least one sharing relationship includes multiple accessing tenants accessing a given set of data from a provider tenant. For each sharing relationship, if a current database has one or more accessing tenants and does not have the provider tenant, data is fetched from the latest-allocated database prior to the current database that has accessing tenants, if such a database exists; if a current database has the provider tenant, data is provided to the earliest-allocated database after the current database that has accessing tenants if such a database exists. The fetching and providing steps are repeated for each allocated database.

Abstract: Systems and methods are disclosed for placing tenants in a cloud based database server, by estimating with a processor a cost of placing a set of tenants on a server using a simulator; estimating a relative importance of different tenant's queries; and selecting an optimal server for each tenant based with a cost-based schedular to maximize profit using the simulator.

Abstract: A method to facilitate data sharing for cloud applications includes determining one or more cost levers for a cloud service provider to share data among applications; determining a costing function that considers a resource cost of creating and maintaining the sharing, potential penalties to be paid if a service level agreement (SLA) is breached by the cloud service provider, and overprovisioning of services from the provider; and interactively answering what-if questions on pricing of services to allow a consumer to explore the cost of data sharing from the provider.
