    Abstract Quantum error-correcting codes are crucial for quantum computing and communication. Currently, these codes are mainly categorized into additive, non-additive, and surface codes. Additive and non-additive codes utilize one or more invariant subspaces of the stabilizer G to construct quantum codes. Therefore, the selection of these invariant subspaces is a key issue. In this paper, we propose a solution to this problem by introducing quotient space codes and a construction method for quotient space quantum codes. This new framework unifies additive and non-additive quantum codes. We demonstrate the codeword stabilizer codes as a special case within this framework and supplement its error-correction distance. Furthermore, we provide a simple proof of the Singleton bound for this quantum code by establishing the code bound of quotient space codes and discuss the code bounds for pure and impure codes. The quotient space approach offers a concise and clear mathematical form for the study of quantum codes.

    Abstract The widespread application of artificial intelligence technology in various fields has made the sustainable development of artificial intelligence courses an important direction in the field of artificial intelligence education and teaching. Therefore, it is particularly important to conduct an in-depth analysis of the current research status of “artificial intelligence courses” from a global perspective. Firstly, this article clarifies the three stages of slow development, rapid development, and mature development of artificial intelligence curriculum research through the number and distribution years of the literature. It also conducts a co-authorship analysis on the distribution of countries, institutions, and authors of artificial intelligence curriculum research and identifies countries, institutions, and core authors that have made greater contributions to artificial intelligence curriculum research. Secondly, due to the involvement of artificial intelligence in many different fields of knowledge, an analysis is conducted on the journals that published papers on artificial intelligence courses. Finally, based on the analysis of keyword density and time span, the current research hotspots of artificial intelligence courses are summarized: artificial intelligence technology empowerment courses, two education directions at different stages of artificial intelligence courses, and teaching forms in the field of artificial intelligence courses. The current research trend of artificial intelligence courses is analyzed from three aspects: teaching format, teaching content, and teaching objects. This article provides a theoretical reference value and practical basis for future research and development in the field of artificial intelligence courses, while also providing experience for the efficient and sustainable development of artificial intelligence courses to a certain extent.

    Abstract In this paper, we researched Pedestrian Dead Reckoning (PDR) with one foot-mounted IMU sensor. The issues of PDR are magnetism noise and accumulated error due to the noise included in acceleration and gyro data. Two methods are proposed in this paper. First is the gait-phase-estimation method with pitch angle for the Zero Velocity Update algorithm. Second is a method for avoiding accumulated errors by updating the roll and pitch angles with acceleration. The two experiments were conducted to examine the error of gait-phase estimation and distance estimations. The relative error of distance was about 7.40% in the case of walking straight and about 12.27% in the case of a shifting travel direction.

    Abstract To explore the mechanism of Hedyotis Diffusae Herba-Smilacis Glabrae Rhizoma(HDH-SGR) in treating lung adenocarcinoma based on big data bioinformatics combined with network pharmacology analysis and molecular docking technology. The chemical components and potential therapeutic targets of HDH-SGR were obtained from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). Lung adenocarcinoma-related genes were obtained from The Cancer Genome Atlas(TCGA), Therapeutic Target Database(TTD), Pharmacogenetics and Pharmacogenomics Knowledge Base(PharmGKB), Online Mendelian Inheritance in Man(OMIM), DrugBank, and GeneCards. "Drug component-target" network was constructed using Cytoscape to screen out key compounds. STRING was used to build protein-protein interaction(PPI) network and core targets were screened out by Cytoscape-CytoNCA topology analysis. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) analyses of target genes were performed by R-clusterProfiler. Finally, key compounds were docked to core target genes using AutoDock. The results showed that 22 active compounds and 499 potential therapeutic targets were obtained from HDH-SGR. A total of 14 332 lung adenocarcinoma-related targets were screened out through six data platforms, including 182 common targets. Fifteen core targets were screened out from the PPI network. GO and KEGG analyses revealed significant enrichment of relevant target genes in various biological processes, cellular functions(e.g., response to lipopolysaccharide, nuclear receptor activity, and ligand-activated transcription factor activity) and close relationship between target genes and non-small cell lung cancer signaling pathways. Based on the results of molecular docking validation, diosgenin, quercetin, naringenin, taxifolin, 2-methoxy-3-methyl-9,10-anthraquinone, stigmasterol, and β-sitosterol were able to bind tightly to the core targets. HDH-SGR can intervene in lung adenocarcinoma through multiple targets and signaling pathways, such as non-small cell lung cancer signaling pathways. The binding of active components in Chinese medicine to key targets is presumedly one of the mechanisms that produce therapeutic effects.

    Abstract Background: This study aimed to analyze the predictive value of multi-slice spiral computed tomography (CT) perfusion imaging for upper gastrointestinal bleeding in patients with cirrhotic portal hypertension. A total of 62 patients with cirrhotic portal hypertension and 28 healthy individuals were included. The results showed that multi-slice spiral CT perfusion imaging had a significant predictive value for upper gastrointestinal bleeding in patients with cirrhotic portal hypertension. The vascular area, number of vascular cross-sections, and gastric coronary vein diameter (GCVD) showed high predictive values, with the vascular area having the best predictive value.
    Aim: To investigate the predictive accuracy of multi-slice spiral CT perfusion imaging for upper gastrointestinal bleeding in patients with cirrhosis and portal hypertension.
    Methods: This study included 62 patients with cirrhotic portal hypertension (disease group) and 28 healthy individuals (control group). The disease group was further divided into two subgroups: Group A (
    Results: We found no difference in hepatic artery (HAP) levels among the three groups (all
    Conclusion: That multi-slice spiral CT perfusion imaging can predict upper gastrointestinal bleeding well in patients with cirrhosis and high blood pressure in the portal vein. GCVD, number of blood vessels, and blood vessel area had high prediction power. The blood vessel area had the best prediction power, with an area under the curve of 0.831.
