文摘Green development and the low-carbon economy in China have operated as parallel,distinct systems,with interactions limited to energy,industry,and technology.Guided by the concept of high-quality growth,green development—centered on sustainability principles and green targets—has focused on green living,production,industrial optimization,system-building,land-use planning,and global ecological objectives,thereby forming a uniquely Chinese green development framework.Similarly,the low-carbon economy,structured around carbon emission goals,development drivers,models of growth,management mechanisms,and international carbon responsibilities,has also developed a distinct framework.Introducing digital intelligence as a new dimension can serve as a coupling point to foster interactive mechanisms between green development and the low-carbon economy.These interactive mechanisms are reflected through smart green cloud collaboration systems and intelligent low-carbon governance platforms,using digital intelligence technology to enhance the synergy between green and low-carbon efforts in energy,carbon management,technology,innovation,governance,and the economy.Through analyzing these mechanisms,and returning to sustainability principles while responding to China's modern development philosophy,a uniquely Chinese theory and framework for green and low-carbon development can be constructed.
文摘Objective:To understand the current situation of career planning awareness and readiness of freshman medical students with a background in digital medicine,and to provide references for optimizing the medical education system and career guidance.Methods:A cross-sectional study was conducted on freshman medical students at a university in Yunnan Province using questionnaire survey.Results:A total of 272 questionnaires were distributed and 264 valid questionnaires were returned,yielding an effective response rate of 97.10%.The average score of digital medical awareness of freshman medical students was(70.50±8.81),and 63.63%of the students had a high awareness(score≧70);The average score of career planning awareness and readiness of freshman medical students was(91.76±14.87),and 60.63%of students had high awareness and readiness(score≧90).Pearson correlation analysis showed that the total score of digital medical awareness was positively correlated with the total score of career planning awareness and readiness(r=0.13,P<0.05).Conclusion:Freshman medical students’career planning awareness and readiness are generally good,but their practical application of digital medical-related skills still needs improvement.It is suggested that schools strengthen the integration of interdisciplinary curriculum,introduce digital vocational training modules,and formulate differentiated guidance strategies for different majors to enhance students’professional competitiveness in the digital medical era.
文摘With the continuous advancement of computer and information technology,education and teaching methods have undergone profound changes.Addressing the challenges in the Engine Structure Principle course-such as its highly practical nature,complex principles,and difficulty in student comprehension-a simulation program for the engine oil supply regulation system was developed using digital technology.This paper analyzes key factors affecting engine fuel supply,including tank pressure,engine inlet total temperature,and fuel viscosity.By encouraging inquiry-based learning,the approach enhances students’understanding of theoretical knowledge,improves teaching efficiency,and yields positive learning outcomes.Additionally,the CDIO(Conceiving-Designing-Implementing-Operating)teaching framework is integrated into the course,strengthening students’ability to apply knowledge comprehensively and collaborate effectively in teams.

文摘Road infrastructure is facing significant digitalization challenges within the context of new infrastructure construction in China and worldwide.Among the advanced digital technologies,digital twin(DT)has gained prominence across various engineering sectors,including the manufacturing and construction industries.Specifically,road engineering has demonstrated a growing interest in DT and has achieved promising results in DT-related applications over the past several years.This paper systematically introduces the development of DT and examines its current state in road engineering by reviewing research articles on DT-enabling technologies,such as model creation,condition sensing,data processing,and interaction,as well as its applications throughout the lifecycle of road infrastructure.The findings indicate that research has primarily focused on data perception and virtual model creation,while realtime data processing and interaction between physical and virtual models remain underexplored.DT in road engineering has been predominantly applied during the operation and maintenance phases,with limited attention given to the construction and demolition phases.Future efforts should focus on establishing uniform standards,developing innovative perception and data interaction techniques,optimizing development costs,and expanding the scope of lifecycle applications to facilitate the digital transformation of road engineering.This review provides a comprehensive overview of state-of-the-art advancements in this field and paves the way for leveraging DT in road infrastructure lifecycle management.

文摘As stated in the Report to the 20th National Congress of the Communist Party of China(CPC),innovation remains at the heart of China’s modernization drive,and it is vital to optimize the allocation of innovation resources,deepen structural scientific and technological reforms,and enhance the overall performance of China’s innovation system.Government incentives have boosted firm R&D and innovation efforts;however,they have also triggered an innovation dilemma where enterprises,capitalizing on their informational advantages,resort to innovation-washing behaviors that undermine the intended purpose of the policies.Based on the information asymmetry theory,this paper conducts an empirical study on how the digital economy affects firms’innovation-washing behavior.The development of the regional digital economy could suppress firm innovation-washing behavior in the region,and such a mitigation effect is primarily caused by an increase in the number of digital industry professionals.According to our heterogeneity analysis,the digital economy has a greater impact on firm innovation-washing behavior for certain types of enterprises,including non-state-owned enterprises(non-SOEs),small and medium-sized enterprises(SMEs),enterprises in less competitive industries,and enterprises in unfavorable business environments.Our mechanism analysis revealed that the digital economy may restrain innovation-washing behavior by reducing information asymmetry between enterprises and external stakeholders.In terms of economic outcomes,the digital economy has the potential to directly influence firm innovation output while also indirectly mitigating the subsequent decline in innovation output by discouraging innovation-washing.This paper enriches the research findings on how the digital economy breaks down“information silos”and offers a potential solution to the“emphasis on input and quantity over quality and efficiency”phenomenon in science and technology innovation practices.

文摘Quantum digital signature(QDS)can guarantee the information-theoretical security of a signature with the fundamental laws of quantum physics.However,most current QDS protocols do not take source security into account,leading to an overestimation of the signature rate.In this paper,we propose to utilize Hong–Ou–Mandel interference to characterize the upper bound of the source imperfections,and further to quantify information leakage from potential side-channels.Additionally,we combine decoy-state methods and finite-size analysis in analyzing the signature rate.Simulation results demonstrate the performance and feasibility of our approach.Our current work can improve the practical security of QDS systems,thereby promoting their further networked applications.
