    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.

    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.

    With the rapid development of artificial intelligence (AI) technology, general large models (GLMs) have become a significant research focus in the AI field. GLMs typically possess an extensive number of parameters, are trained on massive datasets and exhibit robust learning and reasoning capabilities. These models demonstrate outstanding performance in various tasks, including natural language processing, image recognition, and code generation. This paper reviews the evolution of GLMs and the key technology nodes, from the early rule-based systems and traditional machine learning models to the rise of deep learning, the introduction of the Transformer architecture, and the advancements in the GPT series and other GLMS over the world. Despite the significant progress, GLMs face numerous challenges, such as high computational resource demands, data bias, ethical issues, and model interpretability and transparency. This paper analyzes these challenges and explores five key future development directions for GLMs: model optimization, multimodal learning, emotionally intelligent models, data and knowledge dual-driven models, and ethical and societal impacts. By adopting these strategies, GLMs are expected to achieve broader and deeper applications, driving continuous progress in AI technology.

    Dynamic disease risk prediction models are essential for precision prevention strategies. Over the last twenty years, there has been a surge in research focused on these models for precision prevention. However, widely used models(static models) often overlook the impact of changes in predictors over time on disease risk, leading to inevitable calibration drift. This paper reviewed modeling methods for dynamic risk prediction models and provided reference for their development. The conclusions are as follows: As healthcare big data becomes more interconnected and shared, and new methods of statistics and artificial intelligence emerge, the challenge lies in discovering richer predictors, in identifying more accurate modes of action, and in creating interpretable disease risk prediction models which align with biomedical contexts and practical scenarios, to enhance common prevention of common diseases and co-prevention of heterogeneous diseases and to achieve precision and personalized prevention across a spectrum of diseases. This will be a crucial focus for future research on predictive modeling methodologies.

    Urban wastewater treatment plants are important sinks and sources of emerging contaminants, which are a crucial barrier to interrupt its discharge into the aquatic environment. To provide ideas for the prevention and control of emerging contaminants in urban wastewater treatment plants and help achieve the construction of a healthy China, this paper focuses on the categories of emerging contaminants in urban wastewater. We argue that the concentrations of emerging contaminants in wastewater from different districts show significant geographical characteristics, which are closely related to regional environmental conditions, population density, wastewater sources, socio-economic conditions and industrial layout. We analyze the migration and transformation patterns of emerging contaminants in various units of urban wastewater treatment plants. The results indicate that removal of emerging contaminants from wastewater treatment plants is influenced by critical factors including wastewater treatment processes and emerging contaminants categories. We also illustrate that removal of emerging contaminants from urban wastewater treatment plants is currently challenged by the lack of regulations and standards, outdated monitoring technologies, hard-to-construct risk assessment systems, and ineffective removal technologies. We propose appropriate prevention and control strategies to address these challenges.

    With the intensified global warming trend, frequent extreme climatic events have an increasingly significant impact on China's grain production. In 2023, China's grain production was severely impacted by extreme climate, resulting in nationwide output reduction, posing a serious threat to food security. In response to the frequent occurrence of extreme weather, seven countermeasures are proposed: adjusting the national agricultural layout, conducting research and development on crop breeding, constructing agricultural water conservancy facilities, optimizing soil quality, legislating to ensure green agricultural development, promoting agricultural financial services, and establishing an agricultural disaster early warning system. By juxtaposing these measures with the objectives outlined in the 14th Five-Year Plan for National Planting Industry Development, this article provides reference for crafting strategies to response future extreme climatic events in China. The core task for China's future grain production is enhancing long-term capabilities against various disasters and advocating further attention to the challenges of climate change posed on future agricultural production, to ensure secure and stable grain production.

    This study explores the concept related to hydrogen and its manifestation in hydrogen Chinese medicine (HCM) from the perspective of traditional Chinese medicine (TCM) theory. It provides a comprehensive overview of the current research status in hydrogen medicine from both modern medical and TCM perspectives. Furthermore, it outlines the future directions to integrate hydrogen into HCM. In modern medicine, extensive research on hydrogen has targeted at the conditions including respiratory, endocrine metabolic disorders, cardiovascular and cerebrovascular diseases, and eye-related illnesses. Research findings have indicated the hydrogen's beneficial role in prevention and treatment, yet challenges still remain, such as limited clinical trials and undefined molecular mechanisms. HCM is an emerging field of research, which currently only focuses on hydrogen's synergistic effects with traditional Chinese medicines and the development of related equipment. Future research in HCM should delve into how hydrogen aligns with the principles of TCM treatment, establish a theoretical framework for HCM, and develop HCM therapeutic methods. It should also employ modern scientific research methods to evaluate the feasibility and mechanisms of hydrogen under the guidance of TCM theories. Additionally, conducting clinical trials to provide clinical data for HCM applications will provide valuable insights for the diversified development of hydrogen medicine.

    人工智能的飞速发展给生物学研究带来了深远影响,其中,AlphaFold2在蛋白质结构预测领域引发了革命性的突破。评估了AlphaFold2对G蛋白偶联受体(GPCR),结构预测的可靠性,凭借其对蛋白质三维结构的高度准确预测。然而,在实际应用中,AlphaFold2的预测结果并非在所有场景下都足够精确。以GPCR为例,这类重要的药物靶点参与了广泛的生理过程,其结构研究对理解功能机制和药物开发具有重要意义。结果表明,尽管AlphaFold2能够准确捕捉GPCR整体骨架的主要特征,但其预测模型在胞外域与跨膜域的组装、配体结合口袋的形状,以及信号传导界面的构象等方面,与实验解析的高分辨率结构存在显著差异。这些差异限制了AlphaFold2模型在GPCR功能研究和基于结构的药物设计中的应用能力。因此,尽管AlphaFold2为结构预测提供了强大的工具,但其在特定场景下的局限性表明,AI结构预测作为一种辅助工具,尚不能完全取代实验结构生物学,需要联合使用以辅助药理学研究和药物设计。

    The "guardrail provisions" of the United States' CHIPS and Science Act are an important part of the U. S. semiconductor industry's development strategy. The primary purpose was to limit companies with leading-edge semiconductor technology from investing, expanding production, or providing technological licensing in China, as well as restricting U. S. institutions with advanced technology from cooperating with China's counterparts. The detailed regulations of the recently implemented CHIPS fund further clarified the scope of application, exceptions, and punitive measures under the "guardrail provisions". This article introduces the mechanisms of the "guardrail provisions", analyzes the impact of the "guardrail provisions" on the development of semiconductor industry and technological innovation. This article also proposes suggestions for China to respond to the blockade of the "guardrail provisions" from both domestic regulation and international rule perspectives.

    AI for research (AI4R) is a significant change in research methods. The scientific and technological circles should not only pay attention to "AI for Science" (AI4S), but also attach great importance to "AI for Technology" (AI4T); Not only should we focus on the Large Language Model (LLM), but we should also pay more attention to the Large Science Model (LSM). The breakthrough of artificial intelligence mainly relies not on large computing power, but on the transformation of computational models. China should strive to make disruptive innovations on foundation models. AI4R is suitable for combinatorial search of complex problems, and neural network models may be close to the complexity threshold point that can handle difficult problems. One trend in AI4R is to abandon absoluteness, embrace uncertainty, and we should tolerate "black-box models" appropriately for a certain period of time.

    Under the background of the superpower games, the United States actively promotes the de Sinicization of key minerals and constructs a strategic blockade against China, which may seriously affect China's normal resource rights and interests. Based on the critical mineral related data released by the United States Geological Survey from 2013 to 2022, quantitative research was conducted from three perspectives: import dependence, market dynamics, and supply risk. The changes in the security of the critical mineral supply chain in the United States were elucidated, and the means and characteristics of strengthening the security of the critical mineral supply chain in the United States were analyzed. About 90% of critical minerals in the United States rely on imports, with China as its top supplier. The market dynamics of about 70% of critical minerals fluctuate violently, and market instability may amplify the import risk of critical minerals in the United States; About 32% of critical mineral supply risks are high or keep rising, and the production capacity of critical minerals further shifts to some thirdworld countries in Asia, Africa and South America, and the escalation of geopolitical crises may exacerbate mineral supply risks. Based on the analysis of the security situation of the key mineral supply chain in the United States and its security measures to strengthen supply chain, suggestions have been put forward, including systematic planning to respond to the strategic game of key minerals, enhance the influence on the international mineral resource market, deepen overseas development cooperation, and strengthen risk prevention and control.

    The existing multi-agent collaborative control methods based on temporal logic tasks usually adopt formal language to describe the temporal task, convert it into an automaton, multiplicate it with the environment model, and finally complete task planning by performing graph-search in the product automata. The advantages and disadvantages of existing methods are compared and summarized in this paper; Starting from the commonly used control methods which have combined temporal logic languages, the development of three key technologies, namely man-machine fusion heterogeneous team control method, system's robust control of task violation degree and coupling task assignment between human-machine collaboration tasks, are emphatically sorted out. Meanwhile, the good performance of emerging temporal languages such as TSTL in human-machine fusion architecture is also reviewed. Finally, an in-depth analysis was conducted on the scientific and technological bottlenecks in current research on collaborative control, including difficulty in task description, decoupling allocation, and large online computing load. These bottleneck issues which urgently need to be solved in the future development, have become the main study trend of this field in the future.

    Taking China's provincial panel data from 2010 to 2021 as a sample, the entropy weight method is used to measure and calculate the agricultural science and technology innovation and the resilience of grain production system. In addition, the fixed effects model is also applied to analyze the impact of agricultural sci-tech innovation on the resilience of grain production and the mechanism of action. The study shows that agricultural sci-tech innovation significantly improves the resilience of the grain production with a positive spatial spillover effect. Heterogeneity analyses show that agricultural sci-tech innovation has a greater impact on the major grain-producing regions and central China than on the non-major grain-producing regions and east China. Further mechanism analysis indicates that agricultural sci-tech innovation promotes grain production resilience by reducing the amount of chemical fertilizer applied in agriculture, increasing the share of agricultural mechanized operation service personnel and the level of agricultural mechanization. Therefore, it is necessary to continuously strengthen the leading role of sci-tech innovation, accelerate the substitution of agricultural factors, promote the transformation to low-carbon and green agricultural industry, and guide the radiation of innovation and technological spillover, so as to give full play to the role of agricultural sci-tech innovation in enhancing the grain production resilience.

    Large cohort study has become an important open scientific research infrastructure and health decision-making support platform in the field of biomedicine and public health. With increasingly highlighted significance, large cohort construction has been laid out in many countries. In this paper, by focusing on the organizational mechanism, funding source, construction mode, standardization scheme, resource management and sharing strategy, etc. of the European Prospective Investigation into Cancer and Nutrition (EPIC-Europe), the key to its successful implementation and operation was deeply analyzed, in order to provide experience reference for the construction of a comprehensive, shared and open large cohort with multi-agent collaboration. Results show that continuous input and long-term scientific research mechanism guarantee is indispensable to the construction of multi-agent collaborative alliance distributed large-scale cohort, and its sustainable and high-quality construction also requires forward-looking top-level design, a coordinated and unified management mechanism, standard and comprehensive data and biological sample collection, and a sound policy guarantee system. The following suggestions are made: the government should take a leading role in the planning and scientific design to establish an integrated large-scale cohort organization and management system; special projects with long-term stable support should be set up to ensure the continuous and high-quality construction of large cohorts; a standard and unified construction and management scheme need to be established to ensure the standardization and systematization of large cohort resources; the scale, type and quality of data resources should be improved to establish, open and share high-quality large cohorts; reasonable systems for the protection of human genetic resources and the management of intellectual property rights should be further explored.

    The concept of "all-age friendliness" is a nascent but profound topic that impacts the spatial quality and future development of cities. Addressing issues such as insufficient refinement and mismatches between age groups and spatial needs in current urban planning and construction, this study focuses on the main urban area of Wuhan as a research subject. Leveraging big data from online public opinion, combined with techniques such as natural language processing and geospatial statistical analysis, we identify critical spatial issues related to different age groups and their distribution characteristics. The results reveal that spatial issues related to all age groups vary in content and emphasis. Old communities, schools and their surrounding neighborhoods, as well as commercial and office areas, are prone to issues specifically related to certain age groups. Urban transportation spaces and residential areas undergoing renewal are more likely to encounter issues pertaining to all age groups. Conversely, blue and green public spaces represent the least problematic spatial types. Based on these findings, this study provides guidance for the nascent exploration of all-age friendly cities in China, focusing on two aspects: "supporting the use of specific age groups" and "facilitating shared access for all ages." This research contributes to the ongoing efforts in enhancing the urban spatial quality and inclusivity for all age groups.

    Irritable bowel syndrome with predominant diarrhea (IBS-D), characterized by chronic and recurrent diarrhea and abdominal pain associated with defecation, is a common subtype of irritable bowel syndrome (IBS) in China, which seriously affects the quality of patient life.Previous investigation showed that Xingpi capsule is effective in the treatment of IBS but lacks clinical research evidence to provide reference for rational drug use.This study adopted a patient-centered prospective design, and systematically collected and analyzed population characteristics, disease improvement after taking Xingpi capsule in a real clinical diagnosis and treatment environment, as well as patient satisfaction and other information.The aim is to provide realworld evidence for rational drug use by clinicians and to provide reference for the design of clinical research elements for validation study of Xingpi capsule for IBS-D treatment in the absence of clinical evidence.This study observed and analyzed 28 symptom scores, major symptom group scores, gastrointestinal symptom rating scale(GSRS) scores and adverse events of 326 patients treated with Xipi capsule from Oct 2021 to Oct 2022.The results were as follows.Patients with IBS-D were more female than male (about 1.35 times), the proportion of young patients was relatively high (52.76%), and 90.80% of the patients were treated with Xingpi capsule alone.On the first day of treatment, the total symptom score, the major symptom cluster score and the insomnia symptom score were significantly improved (P<0.001), the GSRS score was significantly improved on the third day (P<0.001).Among the 326 patients, 99.08% were satisfied with the therapeutic effect of Xingpi capsule, and 6 (1.84%) had adverse events, including 1 case of nausea, 2 cases of stomach discomfort, 1 case of constipation, 1 case of dry mouth, and 1 case of upper abdominal discomfort.All six patients experienced discomfort within three days of taking the capsule, and discomfort disappeared after two to three days of continuing taking the pill.After 14 days of observation, Xingpi capsule could be used to treat young, middle-aged and elderly IBS-D; and clinical single drug effect was good.It could improve gastrointestinal symptoms such as diarrhea, abdominal pain, esophageal reflux and abnormal stool in patients with IBS-D, and treat the main symptoms of IBS-D within 2 days, with good safety and high patient satisfaction.
