    The discovery of bilayer nickelate superconductor La3Ni2O7 under high pressure has attracted worldwide attention, in which theoretical research plays a vital role. So far, theoretical calculations show that the two eg Ni 3dx2-y2 and 3dz2 orbitals in La3Ni2O7 are crucial to the formation of superconductivity, while the O2 p orbital also appears on the Fermi surface. Multi-orbital models have been proposed based on the above analysis. Various calculations show that La3Ni2O7 has a s± wave pairing symmetry although other pairing symmetries can be obtained. Theoretical calculations shows that the superconducting mechanism is unconventional and closely related to antiferromagnetic fluctuation. The vacancy of apical oxygen has a significant impact on the occurrence of superconductivity. The discovery of trilayer nickelate superconductor La4Ni3O10 under pressure has further enriched the family of nickelate superconductors. And its electronic band structure, multi-orbital model, superconducting pairing symmetry and so on have been investigated and explored theoretically.

    This article focuses on amorphous matters and reviews recent advances in amorphous materials and physics. More recently, more than 30% of the lunar soil collected by China's Chang 'e-5 mission was found to be glassy, further confirming the widespread existence of amorphous matter in the universe. Topological order and inhomogeneity may be hidden behind the seemingly chaotic structure of amorphous materials, so amorphous matters have strange genetic, sensitive and relaxation behaviors, and show a series of excellent physical and chemical properties, such as extreme stability, super-plasticity, super mechanical behavior and excellent soft magnetic properties. The new generation of Zr-based and Fe-based amorphous alloys developed based on order regulation and high flux technology are successfully applied to core components such as folding mobile phone hinges and new energy vehicle motors, indicating that amorphous matters have irreplaceable application advantages. The future development of amorphous matters should focus on introducing a new paradigm of material research, attaching importance to the importance of process innovation, promoting the cross-integration of multi-disciplinary fields, giving full play to the advantages of advanced characterization technology and large scientific devices, and creating a whole-chain innovation model for production, university and research, so as to actively promote the rapid development of amorphous materials and physics, and expand the application of amorphous matters in high-tech fields. Make the future of mankind a better place.

    Graph neural network (GNN) is another major development after convolutional neural network, and it belongs to an emerging deep learning method in the field of artificial intelligence. It mainly preserves the topological information in graph data through end-to-end learning from graph to prediction, and overcomes the defect that traditional deep learning cannot be applied to non-Euclidean data. This paper demonstrates the advantages of GNN for processing complex non-Euclidean data through the application progress of GNN in brain-related mental and nervous system diseases. GNN shows great potential in the medical field, furthermore, the network structure of the syndrome differentiation system of Traditional Chinese Medicine (TCM) is similar to the structure of the brain active area, and it is highly compatible with the schematic unstructured data processed by GNN, so GNN has great application prospect in the field of TCM. This article summarizes the application of GNN in the field of TCM and brain-related mental and nervous system diseases, and analyzes the advantages of TCM diagnosis and treatment models from the theoretical level, in order to explore and build a GNN-based model for fitting with the thinking mode of "syndrome differentiation and treatment" and realizing the objective diagnosis in TCM. It provides new means for solving the problems of complex relationship representation in TCM and mining the individual characteristics of patients. And it also provides a favorable tool for revealing the potential mechanism of TCM from multiple perspectives, and developing and improving the science of TCM.

    Extracorporeal membrane oxygenation (ECMO) is an effective extracorporeal life support measure that played a crucial role in the treatment of critically patients with COVID-19. However, its core component, oxygenation membrane for ECMO, has been monopolized by foreign countries for a long time. This study used the Incopat and retrieved form it the patents in the field of oxygenated membranes for ECMO worldwide, which were then analyzied as the original data to disclose the trend and trajectory of technology development, the layout of global market and technology from the perspective of patents. The result shows that COVID-19 has stimulated the development of technology. China becomes the world's third largest source and distribution of patent applications in the field as well as an important target market, but its high-value patents account for a small proportion. Except for a few patents related to membrane preparation and its device, membrane modification, and membrane module, most of the Chinese patents involve the optimal design of oxygenator and related auxiliary technologies, and most of them are utility model patents. The preparation method and optimization process of hollow fiber membrane for ECMO, new polymer materials, membrane modification and composite membrane research are the current hot research topics. Recently Chinese patents reported the preparation technology of PMP hollow fiber membranes for ECMO and related devices, which are expected to achieve a breakthrough in the preparation technology of high-performance PMP hollow fiber membranes. Innovations can be made for the existing defects of polymer material synthesis technology and membrane preparation technology. Meanwhile, it is necessary to increase the research of biocompatibility modification technology and find new materials with better performance to achieve technological breakthrough. Promoting the localization of oxygenation membranes for ECMO will help the localization of ECMO systems.

    In order to intelligently meet the business requirements of the SG-CIM model designed by the State Grid Corporation of China and improve the quality and sharing of the graph data, this paper proposes a graph structure mapping model based on gaph attention network(GAT). First of all, using the data of SG-CIM model, an SG-CIM knowledge graph and a database table knowledge graph are constructed. The entities embedding in each graph are learned separately through the GAN, which are then embeded into a unified vector space. Finally, the graph structure mapping results of the two graphs are obtained after calculating the similarities based on the distances between the entity vectors. Experiments show that the proposed model achieves good results in automatic mapping of SG-CIM model.

Second, high-end computing resource is limited, and model training has high power consumption and high carbon emissions, which brings environmental problems. Third, it is the socialization of large models that brings about social development problems such as discrimination and prejudice, the spread of false information, invasion of privacy, and impact on employment. In order to overcome the aforementioned challenges, it is essential to build a federal ecosystem (including federal data, federal control, federal management and federal services) with support of block chain and decentralized autonomous organizations (TRUE+DAO, TAO), and provide solutions for the development of artificial intelligence in the new era.

    To summarize the research phases of the efficacy evaluation of stepwise progressive evidence-based treatment, and to verify the efficacy and safety of the core prescriptions of evidence-based treatment of insomnia by individual practitioners, the scientific problems and solution strategies in the three stages of "description-exploration-validation" were compared and analyzed in this paper. Based on the observational study of the evidence-based treatment efficacy by famous TCM practitioners, the further validation of the efficacy was carried out through a multicenter blinded randomized controlled trial design. 133 insomnia patients with TCM classification of phlegm-heat-disturbing-the-mind were used as the study population. The patients were randomly divided into three treatment groups, namely Qing Tan Ning Shen Fang, Xiang Fu Wen Dan Tang and Huang Lian Wen Dan Tang; all of them were prepared as Chinese medicine compound granules and taken for 28 days. The differences in total sleep time (TST) and sleep latency (SL) were observed before and after treatment; the Pittsburgh Sleep Quality Index (PSQI) scores, Insomnia Severity Index (ISI) scores before and after treatment were compared between the groups. After 4 weeks of treatment, sleep efficiency (SE) and clinical efficiency were calculated. After 4 weeks of treatment, the decrease of PSQI score was 4.64, 4.91, and 5.43 in the three groups, respectively; the total sleep time was prolonged by 1.22, 1.14, and 1.62 hours, and the sleep latency was shortened by 43.81, 55.44, and 53.37 minutes on average, the decrease of ISI score was 6.79, 7.98, and 7.43 in the three groups, and the SE was improved by 15.18% and 10.26%, respectively. The overall effective rates were 73.81%, 73.33%, and 76.09%, with no statistically significant differences between groups (P>0.05). Compared with the results of the observational study, the efficacy was reduced. The effective core prescriptions of the famous TCM discriminative treatment are effective, safe and reliable for patients with phlegm-heat disturbed insomnia, and the stepwise progressive discriminative treatment efficacy evaluation research method can gradually increase the level of evidence of TCM clinical research and finally obtain objective and scientific research conclusions.

    The numbers of extreme weather and climate events in many parts of the world are increasing due to climate change, and this phenomenon will become more frequent and severe. A complete and reliable climate observation series over long-time scale is an important basis for interpreting climate change and evaluating model simulation performance. It is also a reliable observation basis for deeply and systematically detecting the characteristics of global, regional or local extreme climate change and predicting the future trend of climate change. In this paper, some important research achievements are summarized, which have been recently made in construction of long-term climate observation series on global, regional and local scales at home and abroad. Several global surface temperature and precipitation climate datasets and their important values for the science of climate change are analyzed. Moreover, technologies and key scientific problems in constructing climate observation series over long-time scale that need to be improved and solved urgently are also discussed. Results indicate that some progress has been made in construction technology of climate observation series over long-time scale for supporting the development of climate change operations. However, there are still some main problems that need to be solved in view of the urgent need of data supply capacity under new situation, i. e., enriching the types of the observed elements, restoring the integrity of historical data, improving the quality of data products, and refining the spatial scale of the object and the temporal scale of the elements. Therefore, a scientific basis can be provided for further enhancing the application value of precious long-term climate observations in meteorological service guarantee and scientific and technological innovation in China.
