Abstract: A preparation method of a silicon-based molecular beam heteroepitaxy material, a memristor, and use thereof are provided. A structure of the heteroepitaxy material is obtained by allowing a SrTiO3 layer, a La0.67Sr0.33MnO3 layer, and a (BaTiO3)0.5—(CeO2)0.5 layer to successively grow on a P-type Si substrate. The silicon-based epitaxy structure is obtained by allowing a first layer of SrTiO3, a second layer of La0.67Sr0.33MnO3, and a third layer of (BaTiO3)0.5—(CeO2)0.5 (in which an atomic ratio of BaTiO3 to CeO2 is 0.5:0.5) to successively grow at a specific temperature and a specific oxygen pressure. The preparation method of a silicon-based molecular beam heteroepitaxy material adopts pulsed laser deposition (PLD), which is relatively simple and easy to control, and can achieve the memristor function and neuro-imitation characteristics. A thickness of the first buffer layer of SrTiO3 can reach 40 nm.

Abstract: Disclosed are a method and a system for bug localization based on a code knowledge graph, including the steps of: extracting source codes from a Git version control system, parsing in the source codes to generate an abstract syntax tree (AST), constructing a code knowledge graph, preprocessing the summary and description of a bug report crawled from a Bugzilla bug tracking system, and performing the named entity recognition to identify bug-related entity sequence, converting the code knowledge graph and the bug-related entity sequence into vector representation through an embedding algorithm, calculating cosine similarities of vector representations between the code knowledge graph and the bug entity sequence, ranking the similarities from high to low to generate a list of suspicious methods, filtering redundant information in the source codes, identifying bug-related entity elements in the bug report, and reserving the bug-related information.
