With the gradual application of knowledge atlas technology in oil and gas exploration and development fields such as intelligent evaluation of oil and gas reservoir and intelligent identification of oil and gas reservoir through logging, the application of knowledge Atlas in oil and gas industry has attracted more and more attention. In view of the problem of knowledge expression and application in E&P sector field, a professional word bank of E&P was established based on web crawler technology, a feature corpus of E&P field was established by extracting E&P sector related achievement documents and literature data, and the principle of E&P knowledge graph ontology construction was formulated and the construction process was defined. The multistage classification system of oil and gas exploration and development knowledge atlas ontology is described and constructed from multiple dimensions such as sector, object and feature, and the knowledge atlas ontology model of oil and gas exploration and development sector domain is formed, which lays a foundation for the in-depth application of knowledge atlas technology in petroleum exploration and development. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

The growth of passenger flow in Qingdao Metro has led to the rise of customer service demand. The existing customer service system is constructed based on NLP and knowledge graph, which has the problems of inaccurate understanding of questions, low correlation of answers, and low passenger satisfaction. With the development of large language model technology, customized large language models combined with domain-specific knowledge are increasingly applied to practical application scenarios. After comparing the mainstream open-source large language models, this paper selects Qwen2-7B model as the base model, combines the special knowledge of Qingdao Metro customer service field, generates the Qingdao Metro special customer service model through pre-training and fine-tuning, and develops the Qingdao Metro intelligent customer service agent by means of retrieval-augmented generation and prompt engineering. The evaluation test shows that the score of the model reaches 87 points, which is greater than the 80 points of the Qwen2-7B general model and the 45 points of the existing customer service system. Compared with the original customer service system of Qingdao Metro, the answer accuracy of the model is increased by 38%, and the answer accuracy is increased by 16% compared with the general model. The proprietary large language model of metro intelligent customer service based on open source large language model can effectively solve passenger problems and improve passenger satisfaction. © 2025 SPIE.

Introduction: The aim of this study was to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of AZd7442 (tixagevimab/cilgavimab) in healthy Japanese adults. Methods: In this randomized, double-blind, placebo-controlled, phase 1 study, AZd7442 was administered intramuscularly (300 or 600 mg) or intravenously (300 or 1000 mg) to healthy Japanese adults. Primary endpoints were safety, tolerability, and pharmacokinetics. Anti-drug antibodies and neutralizing antibody activities were secondary endpoints. results: A total of 40 participants were randomized to receive AZd7442 (n = 30) or placebo (n = 10). Adverse events (AEs) occurred in 12 (40%) and 3 (30%) participants, respectively;there were no deaths, serious AEs, or AEs leading to study withdrawal. Tixagevimab and cilgavimab had mean half-lives of 82.1–95.9 and 77.9–92.0 days, respectively, which were generally similar regardless of administration route. SArS-CoV-2–neutralizing antibody titers were >4-fold higher than baseline levels from day 8 to day 211 in participants receiving AZd7442. Conclusions: AZd7442 was well tolerated in healthy Japanese adults, with predictable pharmacokinetics and an extended half-life, consistent with previous studies. ***, NCT04896541. © 2023 Japanese Society of Chemotherapy, Japanese Association for Infectious diseases, and Japanese Society for Infection Prevention and Control

For the past decades, the density of drAM has been remarkably increased by making access transistors and capacitors smaller in size per unit area. However, shrinking devices far beyond the 10 nm process node increasingly poses process and reliability challenges. As Flash technology made a pivotal and successful innovation via 3d NANd, drAM technology may also adopt vertical stacking memory cells. Vertically stacked drAM (VS-drAM) continues to increase bit density on a die by increasing the number of layers along with reducing the size of the transistor. In this paper, the opportunities and challenges of VS-drAM are discussed. © 2023 JSAP.

It's necessary to solve the problem of fine characterization and efficient simulation of three types of fractures, i.e. natural fractures, artificial fractures and complex fracture network, for the development optimization design and scheme adjustment of unconventional oil and gas reservoirs. This paper describes a set of efficient and practical fracture characterization techniques for reservoir numerical model, which integrates various numerical simulation methods of fractures in different scales, including single-medium equivalent model, LGr model, double-medium model, MINC model, non-structural discrete fracture model and embedded discrete fracture model. For different reservoir types and different fracture dimensions, different models are adopted to depict the spatial distribution and fluid flow characteristics of fracture-matrix, matrix-matrix and fracture-fracture. The application in a shale gas shows that the set of fracture characterization methods can accurately describe the shape, geometric characteristics and spatial position of natural fractures, artificial fractures and fracture network. The methods also can simulate the fluid flow characteristics in multi-scale fracture network efficiently, and accurately predict the productivity of fracture network.
