Three key techniques used in this system have been discussed. First, a combined co-phase traction power supply system is applied at traction substations for compensating negative sequence current and eliminating phase splits at exits of substations; design method and procedure for this system are presented. Second, a new bilateral traction power supply technology is proposed to eliminate the phase split at section post and reduce the influence of equalizing current on the power grid. Meanwhile, power factor should be adjusted to ensure a proper voltage level of the traction network. Third, a seg- mental power supply technology of traction network is used to divide the power supply arms into several segments, and the synchronous measurement and control technology is applied to diagnose faults and their locations quickly and accurately. Thus, the fault impact can be limited to a min- imum degree. In addition, the economy and reliability of the new generation traction power supply system are analyzed.展开更多

While these innovations deliver operational improvements, the heightened interconnectivity introduces significant cybersecurity challenges, particularly within military logistics, where mission-critical operations and life-safety concerns are paramount. This paper examines these unique cybersecurity requirements, focusing on advanced persistent threats, supply chain poisoning, and data breaches that could compromise sensitive operations. The study proposes a hybrid cybersecurity framework tailored to military logistics, integrating resilience, redundancy, and cross-jurisdictional security measures. Real-world applicability is validated through simulations, offering strategies for securing supply chains while balancing security, efficiency, and flexibility.展开更多

文摘A comprehensive assessment of grain supply,demand,and ecosystem service flows is essential for identifying grain movement pathways,ensuring regional grain security,and guiding sustainable management strategies.However,current studies primarily focus on short-term grain provision services while neglecting the spatiotemporal variations in grain flows across different scales.This gap limits the identification of dynamic matching relationships and the formulation of optimization strategies for balancing grain flows.This study examined the spatiotemporal evolution of grain supply and demand in the Beijing-Tianjin-Hebei(BTH)region from 1980 to 2020.Using the Enhanced TwoStep Floating Catchment Area method,the grain provision ecosystem service flows were quantified,the changes in supply–demand matching under different grain flow scenarios were analyzed and the optimal distance threshold for grain flows was investigated.The results revealed that grain production follows a spatial distribution pattern characterized by high levels in the southeast and low levels in the northwest.A significant mismatch exists between supply and demand,and it shows a scale effect.Deficit areas are mainly concentrated in the northwest,while surplus areas are mainly located in the central and southern regions.As the spatial scale increases,the ecosystem service supply–demand ratio(SDR)classification becomes more clustered,while it exhibits greater spatial SDR heterogeneity at smaller scales.This study examined two distinct scenarios of grain provision ecosystem service flow dynamics based on 100 and 200 km distance thresholds.The flow increased significantly,from 2.17 to 11.81million tons in the first scenario and from 2.41 to 12.37 million tons in the second scenario over nearly 40 years,forming a spatial movement pattern from the central and southern regions to the surrounding areas.Large flows were mainly concentrated in the interior of urban centers,with significant outflows between cities such as Baoding,Shijiazhuang,Xingtai,and Hengshui.At the county scale,supply–demand matching patterns remained consistent between the grain flows in the two scenarios.Notably,incorporating grain flow dynamics significantly reduced the number of grain-deficit areas compared to scenarios without grain flow.In 2020,grain-deficit counties decreased by28.79 and 37.88%,and cities by 12.50 and 25.0%under the two scenarios,respectively.Furthermore,the distance threshold for achieving optimal supply and demand matching at the county scale was longer than at the city scale in both grain flow scenarios.This study provides valuable insights into the dynamic relationships and heterogeneous patterns of grain matching,and expands the research perspective on grain and ecosystem service flows across various spatiotemporal scales.
文摘As a critical department ensuring the sterility of hospital instruments,the Sterile Supply Center(SSC)directly impacts the sterility status of clinical instruments through its sterilization qualification rate.Geriatric patients,due to physiological decline and compromised immune function,constitute a high-risk group for hospital-acquired infections,with more stringent requirements for instrument sterility.This paper analyzes the current status and influencing factors of sterilization qualification rates in SSCs,explores the mechanistic association between sterilization qualification rates and infections in geriatric departments,and proposes targeted strategies to improve sterilization qualification rates.It highlights the pivotal role of SSC instrument sterilization in infection prevention and control for geriatric patients,providing theoretical basis and practical guidance for optimizing SSC management,reducing infection rates in geriatric departments,and ensuring the safety of elderly patients’medical care.These findings aim to enhance overall infection management standards in hospitals.

文摘The recent Russian-Ukrainian crisis has had a substantial impact on the global natural gas supply landscape and brought major challenges to liquified natural gas(LNG)supply chain safety in many countries.However,academic research in this field remains scarce.This study aims to analyze the global LNG marine supply network changes during the recent Russian-Ukrainian crisis.Big data analytics are applied to the global vessel trajectory information recorded by automatic identification system(AIS).The weighted degree index indicates that global LNG marine supply is still primarily led by a few exporting countries,and the Middle East Port of Ras Laffan now occupies the central position.In 2022,the betweenness centrality and other indicators of the LNG shipping network showed a high middle and low end,indicating that the network has a certain degree of resilience.After the Russian-Ukrainian crisis happened,LNG exports from Qatar,the United States,and Russia increased.Resource flows have reshaped the competitive standing of countries.The European LNG market witnessed a significant intensification in the export competition between Russia and the United States.Despite the ongoing crisis,Russia's LNG export competitiveness remained resilient and displayed no indications of weakening.The results show new evidence for the changes in global natural resources marine supply influenced by the geopolitical events among countries.This has important implications for policymaking of LNG supply safety to the countries that rely heavily on imports.

文摘The Qinghai–Xizang Plateau is a primary water supply region in Asia.The Lhasa River Basin is the political,economic,and cultural core area and main cultivation area of Qinghai–Xizang Plateau and is considered ecologically fragile.With uneven spatial and temporal distribution of water resources,mismatched supply and demand may accentuate differences in distribution and affect the security of regional water resources.This study employed system dynamics(SD)to measure the supply and demand of water supply services and analyzed the correlation between supply and beneficiary areas by evaluating the supply and demand overlap.Moreover,the 2030supply–demand relationship was predicted,the pattern of sustainable development of the basin is discussed,and optimization suggestions are proposed.The range of water supply service beneficiary areas in the Lhasa River Basin shows an increasing trend from 2005 to 2020.The spatial distribution of water supply in 2030 is predicted to be the same as that in 2020,while the total amount of water supply is expected to decrease.By 2030,the largest proportion of water demand will be industry,followed by agriculture,forestry,and animal husbandry.Overall,there is a mismatch between water supply and demand services in the Lhasa River Basin,and it is essential to develop a reasonable water resource management and allocation policy as well as an optimized ecological management strategy for the basin through integrated planning.Here,we provide suggestions for the sustainable development and ecological environmental protection of the Lhasa River Basin.

文摘As global climate change problems become increasingly serious,the world urgently needs to take practical measures to deal with this environmental issue.In this sense,China’s carbon peaking and carbon neutrality goals endowed an ingenious solution.Various industries in China have actively responded to this policy call,and various enterprises have started to carry out the work of carbon emission reduction,especially in water supply industry.In order to reduce carbon emission,we must first calculate carbon emissions and understand the level of carbon emission.At present,the carbon emissions accounting of water supply industry is mostly carried out on the partial work of some individual units within the enterprise,and there is no accounting case for the whole process of water supply work.This work innovatively proposes a method to calculate the carbon emissions generated in the whole water supply procedure.The carbon emission in the whole water supply procedure originates from the leakage of water supply network and the maintenance of water supply network,and all the carbon emissions involved in these two aspects are calculated.Moreover,the key points of carbon emission reduction are analyzed according to the accounting results,and a potential carbon emission reduction scheme is proposed.The research can provide a reference for the overall carbon emission accounting strategies and the construction of carbon emission reduction plans in the future.

文摘Unlike the traditional traction power supply system which enables the electrified railway traction sub- station to be connected to power grid in a way of phase rotation, a new generation traction power supply system without phase splits is proposed in this paper. Three key techniques used in this system have been discussed. First, a combined co-phase traction power supply system is applied at traction substations for compensating negative sequence current and eliminating phase splits at exits of substations; design method and procedure for this system are presented. Second, a new bilateral traction power supply technology is proposed to eliminate the phase split at section post and reduce the influence of equalizing current on the power grid. Meanwhile, power factor should be adjusted to ensure a proper voltage level of the traction network. Third, a seg- mental power supply technology of traction network is used to divide the power supply arms into several segments, and the synchronous measurement and control technology is applied to diagnose faults and their locations quickly and accurately. Thus, the fault impact can be limited to a min- imum degree. In addition, the economy and reliability of the new generation traction power supply system are analyzed.
文摘The concept of Supply Chain 4.0 represents a transformative phase in supply chain management through advanced digital technologies like IoT, AI, blockchain, and cyber-physical systems. While these innovations deliver operational improvements, the heightened interconnectivity introduces significant cybersecurity challenges, particularly within military logistics, where mission-critical operations and life-safety concerns are paramount. This paper examines these unique cybersecurity requirements, focusing on advanced persistent threats, supply chain poisoning, and data breaches that could compromise sensitive operations. The study proposes a hybrid cybersecurity framework tailored to military logistics, integrating resilience, redundancy, and cross-jurisdictional security measures. Real-world applicability is validated through simulations, offering strategies for securing supply chains while balancing security, efficiency, and flexibility.

文摘Blockchain Technology(BT)has emerged as a transformative solution for improving the efficacy,security,and transparency of supply chain intelligence.Traditional Supply Chain Management(SCM)systems frequently have problems such as data silos,a lack of visibility in real time,fraudulent activities,and inefficiencies in tracking and traceability.Blockchain’s decentralized and irreversible ledger offers a solid foundation for dealing with these issues;it facilitates trust,security,and the sharing of data in real-time among all parties involved.Through an examination of critical technologies,methodology,and applications,this paper delves deeply into computer modeling based-blockchain framework within supply chain intelligence.The effect of BT on SCM is evaluated by reviewing current research and practical applications in the field.As part of the process,we delved through the research on blockchain-based supply chain models,smart contracts,Decentralized Applications(DApps),and how they connect to other cutting-edge innovations like Artificial Intelligence(AI)and the Internet of Things(IoT).To quantify blockchain’s performance,the study introduces analytical models for efficiency improvement,security enhancement,and scalability,enabling computational assessment and simulation of supply chain scenarios.These models provide a structured approach to predicting system performance under varying parameters.According to the results,BT increases efficiency by automating transactions using smart contracts,increases security by using cryptographic techniques,and improves transparency in the supply chain by providing immutable records.Regulatory concerns,challenges with interoperability,and scalability all work against broad adoption.To fully automate and intelligently integrate blockchain with AI and the IoT,additional research is needed to address blockchain’s current limitations and realize its potential for supply chain intelligence.

文摘The interaction between supply chain relationships and corporate finance has become a focal issue in academic and practical circles,especially under the dual drivers of globalization and marketization.This paper systematically reviews existing research on this topic,covering theoretical foundations from perspectives such as agency theory,stakeholder theory,and co-opetition game theory,which explain the nature of customer-supplier relationships.It also combs through empirical studies from four core angles:competition-cooperation,signal transmission,spillover effects,and information transfer,summarizing findings on how supply chain relationships impact corporate investment,financing,operations,and performance,as well as existing controversies.The aim is to clarify the research context,identify theoretical and empirical gaps,and provide theoretical support and direction for deepening future research on supply chain and corporate finance.
文摘With the increasing importance of supply chain transparency,blockchain-based data has emerged as a valuable and verifiable source for analyzing procurement transaction risks.This study extends the mathematical model and proof of‘the Overall Performance Characteristics of the Supply Chain’to encompass multiple variables within blockchain data.Utilizing graph theory,the model is further developed into a single-layer neural network,which serves as the foundation for constructing two multi-layer deep learning neural network models,Feedforward Neural Network(abbreviated as FNN)and Deep Clustering Network(abbreviated as DCN).Furthermore,this study retrieves corporate data from the Chunghwa Yellow Pages online resource and Taiwan Economic Journal database(abbreviated as TEJ).These data are then virtualized using‘the Metaverse Algorithm’,and the selected virtualized blockchain variables are utilized to train a neural network model for classification.The results demonstrate that a single-layer neural network model,leveraging blockchain data and employing the Proof of Relation algorithm(abbreviated as PoR)as the activation function,effectively identifies anomalous enterprises,which constitute 7.2%of the total sample,aligning with expectations.In contrast,the multi-layer neural network models,DCN and FNN,classify an excessively large proportion of enterprises as anomalous(ranging from one-fourth to one-third),which deviates from expectations.This indicates that deep learning may still be inadequate in effectively capturing or identifying malicious corporate behaviors associated with distortions in procurement transaction data.In other words,procurement transaction blockchain data possesses intrinsic value that cannot be replaced by artificial intelligence(abbreviated as AI).
文摘The rapidly growing seaweed farming contributes to food,feed,biofuel,and biochemicals,with Indonesia being the largest exporter of raw seaweed(53.35%)but low in carrageenan derivative products(4.49%).Sustainable farming supports SDG 13 and SDG 14 through emission reduction,marine ecosystem conservation,and increased biodiversity.However,its supply chain faces challenges in raw material availability,such as fluctuating harvests,inconsistent quality,limited logistics infrastructure,and market price volatility.Therefore,good environmental management is needed to optimize raw materials in carrageenan production through resource efficiency,environmentally friendly products,environmental regulations,and market and stakeholder awareness.This study identifies factors in the environment-based supply chain that influence the development of carrageenan production centers and analyzes their ecological impacts using quantitative SEM analysis.SEM analysis reveals that resource efficiency,waste management,environmental regulations,and stakeholder awareness and commitment are the main influencing factors.shows significant factors including raw material efficiency,waste management,and environmental regulations.Environmentally based supply chain integration for the development of carrageenan production center areas can be done by;focusing on sustainability and minimal environmental impact,support for achieving SDG 12,13,and 14,strategies for sustainable raw material management,circular economy,sustainability certification,renewable energy and environmentally friendly technology,and stakeholder collaboration and awareness.
文摘The rapid transformation of Arctic maritime routes,driven by diminishing sea ice and shifting geopolitical conditions,presents both opportunities and challenges for global shipping.This study develops an integrated optimization framework for sustainable Arctic marine logistics,grounded in Agile Supply Chain Theory(ASCT),to address cost efficiency,environmental sustainability,and operational robustness under climate and policy uncertainty.A Mixed‐Integer Linear Programming(MILP)model was employed to optimize vessel routing across Arctic corridors,incorporating Energy Efficiency Operational Indicator(EEOI)and Carbon Intensity Indicator(CII)metrics directly into the objective function.Scenario analyses tested performance under varying climate conditions and policy constraints.The model was parameterized using vessel operational data from Arctic shipping logs,environmental datasets from ESA CryoSat‐2 and NSIDC,port accessibility records from Arctic port authorities,and economic data from Clarksons and the World Bank,ensuring realistic and replicable inputs for the analysis.Results demonstrate that ASCT‐based optimized routes achieved an average 14.8%reduction in operating costs,12.3%reduction in CO₂emissions,and an 11.6%improvement in EEOI,with the majority of voyages improving by at least one CII grade.Robustness analysis showed that optimized routes maintained up to 14.7 percentage points higher feasibility under severe ice scenarios and reduced cost volatility by 20–28%under carbon tax regimes.These findings confirm the value of embedding agility and resilience principles into Arctic shipping,aligning operational efficiency with International Maritime Organization(IMO)decarbonization objectives.The study extends ASCT into extreme maritime contexts,offering a replicable model for sustainable route planning in high‐risk logistics sectors.
