    The rapid development of deep learning raises a massive demand for computing power. However, traditional siliconbased chips based on the von Neumann architecture with physically separated memory and computing units, are facing critical issues such as the "memory wall", and hence the increase of chip computing power is gradually hitting a bottleneck. To address this problem, researchers have been inspired by the working mechanism of biological brain and proposed a computing-inmemory architecture based on memristors. This novel architecture is expected to achieve several orders of magnitude improvement in energy efficiency and speed over the von Neumann architecture for tasks such as artificial neural networks. It is one of the most promising technologies to achieve ultra-low power consumption and ultra-high computing power. This article first reviews the working mechanisms of various types of memristors, and summarizes the latest device research internationally. Then, the progress on application demonstrations of memristor-based computing-in-memory chips such as neural networks, signal processing, and machine learning are reviewed. The current challenges in this field and further research directions are concluded in the end.

    This paper provides an overview of the current development status of hydrogen energy highway transportation, rail transit, shipbuilding, and aviation in China. It analyzes the comprehensive performance of hydrogen fuel cell vehicles in China and points out that the challenges faced by Chinese hydrogen energy vehicles are mainly high costs of vehicles and fuel and insufficient refueling infrastructure. However, as China steps into the middle and late stage of urbanization, heavy-load transportation and special transportation with fixed routes provide opportunities for the development of hydrogen vehicles, and family passenger vehicles will become an important direction. Hydrogen energy rail transit will also play a role in areas where electrification is difficult. Ships and aircraft powered by hydrogen compounds will become the focus of shipbuilding and aviation industries. In the future, hydrogen energy transportation should improve planning, promote technological integration and innovation, develop new hydrogen energy transportation travel modes, build a sound policy system, and adopt carbon market mechanism to achieve a new leap.

    科学的飞速发展和文化的缓慢变化发生了矛盾。百年来,中国对传统文化的主流观点曾经出现多次反复,至今缺乏系统的反思,成为当前学术界发挥科学创新潜力的一大障碍。本文从历史回顾和中外比较入手,提出当现代科学在欧洲产生时,中国曾坐失参与的良机;当试图引入西方科技时,又因为方向错误遭受失败,结果使得科学成为西方的特色和东方的弱点。东西方差异的根源在于大陆文明和海洋文明的不同属性,可以上溯到2000多年前古希腊和春秋列国的2大源头。当今世界上这2大文明的经济基础正在消失,新时代的科技发展必将产生新型的全球文明。呼吁从历史反思入手,重新认识中国传统文化,争当国际学术界铸造全球新文明的排头兵。

    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.

    China has promised to achieve the "dual-carbon" goal in order to reduce climate warming caused by human-induced CO2 emissions, accelerate the transition of the electricity system toward renewable energy, and provide impetus to green development. Starting from summarizing the trend of recent studies, this paper encompasses the demand for energy transitions to meet the "dual-carbon" goal, analyzes the environmental problems in the processes of energy transition, and identifies the potential impacts of the production and operation of renewable energy on the environment and ecology. To cope with the challenge of achieving the "dual-carbon" goal, the trends of growth in power generation and energy consumption from 2021 to 2060 are predicted by analyzing the historical growth of renewable energy from 2010 to 2021. In addition, this paper analyzes the demand for land, power transmission, energy storage, and investment for the development of photovoltaic and wind power in China by taking into account the state-of-the-art estimate of photovoltaic and wind power generation. Based on the analysis, it is extrapolated that the renewable growth rate of clean energy in China is insufficient to satisfy the pledges aligning with the "dualcarbon" goal, therefore it is required to overcome the inertia in the energy and economic systems to strengthen the process of energy transition and increase the share of renewable energy in total energy supply. Lastly, a number of suggestions for policy are provided for accelerating the energy transitions to achieve the goal at a low economic cost.

Kaplan-Meier method was used to calculate the estimated survival rate, Cox proportional risk regression model was used to estimate the risk ratio between the two groups, and the incidence of end events, estimated survival rate, physical strength and quality of life scores were compared between groups. The mortality and loss of follow-up in exposure group was lower than that in non-exposure group before and after matching (P<0.05). The survival analysis showed that the estimated survival rate of the exposure group before and after matching was higher than that of the non-exposure group. The estimated survival rates of the two groups at the 18th month were 0.872 and 0.823 before the match, and 0.865 and 0.816 after matching, respectively. There was a significant difference in the survival curve between the two groups (P<0.05). The risk ratio (HR) before and after matching was 0.661 and 0.474, respectively. For ECOG-PS score before and after matching, the proportion of zero point in exposure group at the 6th and 18th month was higher (P<0.05). After matching, the EQ-VAS of exposure group was significantly higher than that of non-exposure group at the 6th month (P<0.05). The clinical application of Zilongjin tablets can reduce the incidence of death end points and improve the survival rate of patients with non-small cell lung cancer. Compared with the non-exposure group, it also showed potential advantages in maintaining patients' physical strength and quality of life scores.

    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.

    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.
