Abstract: Methods and systems are disclosed for security management in an industrial control system (ICS). An event entity detection and linking module generates a model for a plurality of event entities extracted from a plurality of different data sources including one ICS data source and one IT data source. The model encodes a set of linked event entities and their relationships, each event entity associated with a vector of attribute value pairs. A data standardization of domain knowledge includes translating, by a machine learning application, extracted knowledge base information to rules for the constraints and using the rules to validate the constraints and to add new constraints. A fusion module performs temporal correlation detection across data streams of the different data sources for establishing causality between triplets of association models within a defined time span.

Abstract: The present disclosure provides a method and apparatus for generating a front-end code. The method includes: acquiring attribute information of view elements in a target UI view interface; determining child view elements corresponding to a given parent view element based on the attribute information of the view elements; determining, according alternately to row correlation information and column correlation information between the child view elements, nodes at different levels of a DOM, tree corresponding to the parent view element except a root node until each leaf node is an individual child view element, to obtain the DOM tree; and generating a complete front-end code corresponding to the target UI view interface based on the DOM tree.

Abstract: Provided is a double-gene knockout vector system, a method for preparing porcine fibroblasts with both CD163 gene and CD13 gene being knocked-out, prepared porcine fibroblasts, and a method for preparing a gene-edited pig with both CD163 gene and CD13 gene being knocked-out. The vector system of the present disclosure comprises a CD163 gene knockout vector and a CD13 gene knockout vector. The CD163 gene knockout vector comprises a gene editing vector backbone and a DNA fragment ligated to the gene editing vector backbone, with a nucleotide sequence of the DNA fragment being shown in any one of SEQ ID NOs: 1-3. The CD13 gene knockout vector comprises a gene editing vector backbone and a DNA fragment ligated to the gene editing vector backbone, a nucleotide sequence of the DNA fragment being shown in any one of SEQ ID NOs: 4-6.
