The invention discloses a method, a system and equipment for generating ECharts chart resources based on a server side. The method is executed in a Node.js environment and comprises the following steps: receiving and analyzing a chart generation request; loading an ECharts configuration template and obtaining original data, and generating a complete configuration item after standardization processing; creating a virtual DOM (Document Object Model) environment and container elements through the JSDOM; creating an off-screen canvas based on Canvas, initializing an ECharts instance and executing rendering; encoding the rendering result into an image data stream; and performing format adaptation and distribution according to the terminal type. The invention further provides a cross-end consistency guarantee mechanism, a block rendering optimization mechanism, an intelligent distribution mechanism and the like. Complete decoupling of the ECharts and the server environment is achieved, static chart resources can be efficiently generated, large data volume processing is supported, cross-terminal display consistency is ensured, the performance and safety of chart generation are remarkably improved, and the application range of chart generation is remarkably widened.

This application discloses a method, apparatus, device, and storage medium for dynamic isolation and allocation of virtual network addresses, relating to the field of virtual internet technology. The method includes receiving resource request information from a user, determining the currently allocated target virtual network address, and then determining the target network access zone where the target virtual network address resides; obtaining the target tenant identifier corresponding to the target network access zone; and accessing resource information under the target tenant associated with the target tenant identifier through the resource request information. By establishing the correspondence between the target virtual network address, the target network access zone, and the target tenant identifier, the method solves the problems of missing tenant isolation and inefficient fault recovery in related technologies, thereby achieving technical effects such as improved fault recovery efficiency, reduced data leakage risk, and enhanced data security.

The invention provides a data synchronization method and device, equipment, a medium and a program product, and relates to the field of big data. Receiving remote log transmission requests of a plurality of synchronization services through a log agent, requesting a log file from the source end database through the log agent based on the log analysis breakpoint, receiving a target log file from the source end database, and storing the target log file in a local log storage unit, the plurality of synchronization services share and analyze; according to the method, the log requests of the multiple synchronization services are received in a centralized mode through the log agent, the target log files are uniformly obtained from the source end database based on respective analysis breakpoints and locally cached, multi-service efficient sharing and collaborative analysis are achieved, repeated pulling is avoided, the database load is reduced, and the synchronization efficiency is improved.

The application discloses a biological age evaluation method and system based on whole life cycle DNA methylation and application, and belongs to the technical field of bioinformatics. First, the obtained original DNA methylation data is subjected to quality control and standardization processing; then, differential methylation sites significantly related to calendar age are screened as features; next, taking calendar age as a target variable, a regression model is constructed by adopting a LightGBM gradient boosting framework to obtain a methylation clock model; subsequently, the model is used to predict the DNA methylation age of an individual, and an epigenetic age acceleration value is calculated based on the deviation of the DNA methylation age from the calendar age; finally, the age acceleration value is subjected to correlation analysis with health or physiological indexes in different life stages, so as to evaluate the biological aging state of the individual and predict related health risks. The application covers the whole life cycle, is suitable for Chinese population, and can provide an effective tool for clinical disease risk prediction, health management and anti-aging intervention effect evaluation.

The invention relates to the technical field of network communication, in particular to a software-defined networking method and device based on agency, the initiative of connection is transferred to an agency node closer to a switch, the path and time of connection establishment are shortened, the method and device are especially suitable for scenes with a large number of switches and topology dynamic changes, and the efficiency is improved. According to the method, the security genes of the master and slave control channels are inherited and lightweight adaptation is carried out, and the performance bottleneck and security shortages of the traditional SDN southbound channel are fundamentally solved through the original design of intelligent event filtering, multi-path processing and the like, so that a solid end guarantee is provided for stable and efficient operation of the whole hierarchical control architecture.
