Low-dimensional physics provides profound insights into strongly correlated interactions,leading to enhancedquantum effects and the emergence of exotic quantum states.The Ln_(3)ScBi_(5)family stands out as a chemicallyversatile kagome platform with mixed low-dimensional structural framework and tunable physical properties.Ourresearch initiates with a comprehensive evaluation of the currently known Ln_(3)ScBi_(5)(Ln=La-Nd,Sm)materials,providing a robust methodology for assessing their stability frontiers within this system.Focusing on Pr_(3)ScBi_(5),we investigate the influence of the zigzag chains of quasi-one-dimensional(Q1D)motifs and the distorted kagomelayers of quasi-two-dimensional(Q2D)networks in the mixed-dimensional structure on the intricate magneticground states and unique spin fluctuations.Our study reveals that the noncollinear antiferromagnetic(AFM)moments of Pr^(3+)ions are confined within the Q2D kagome planes,displaying minimal in-plane anisotropy.Incontrast,a strong AFM coupling is observed within the Q1D zigzag chains,significantly constraining spin motion.Notably,magnetic frustration is partially a consequence of coupling to conduction electrons via Ruderman-Kittel-Kasuya-Yosida interaction,highlighting a promising framework for future investigations into mixed-dimensional frustration in Ln_(3)ScBi_(5) systems. 展开更多

Based on the frequency of themes covered at the 35th International Geographical Congress(IGC)and the 2024 American Association of Geographers Annual Meeting(AAG-AM),we present an integrated analysis of current research hotspots in geography.The interdisciplinary approach of geography in tackling global challenges,including climate change,urbanization,and sustainable development is highlighted.Hotspot analysis of the 35th IGC reveals the prominence of“Tourism,Leisure,and Global Change,”and“Urban Geography”as key themes,whereas the 2024 AAG-AM placed more emphasis on“GeoAI and Deep Learning,”and“Geospatial Data Science for Sustainability.”Frontier analysis,based on emerging research beyond the two conferences,highlights major critical issues being confronted by geographers,notably Earth’s surface systems,spatial patterns of human activities,intelligent remote sensing,climate change adaptation,biodiversity conservation,hazards and disaster risk,planetary boundaries,coupled human and natural systems,and global and regional sustainability.The analysis demonstrates that geographical research is becoming more diverse and systematic,and artificial intelligence technology is increasingly being harnessed.This not only reflects specific regional interests and priorities but also shows the dynamic development of geographical research and its important role in dealing with the challenges of the 21st century. 展开更多

Platelet rich plasma(PRP)is an autologous blood product rich in platelets,showing promise in reducing inflammation and accelerating healing.While extensively utilized in plastic surgery,dermatology,and osteoarthritis treatment,its application in anterior cruciate ligament(ACL)injuries is limited.This article examines PRP's potential in ACL reconstruction(ACLR),exploring its history,current usage,controversies and future directions.PRP has demonstrated significant early benefits in ligamentisation and vascularisation post-ACLR,though its long-term efficacy is inconsistent.Studies suggest that PRP may serve as both an adjunct therapy in ACLR to enhance initial healing and reduce postoperative complications,and as a non-surgical alternative for small ACL tears.Despite these promising findings,outcome variability necessitates further high-quality research to optimize PRP formulations and determine its most effective applications.The exploration of PRP as a treatment modality in ACLR offers promising but varied outcomes.PRP holds considerable promise as both an adjunct and alternative to traditional ACLR.This article underscores the need for targeted research to fully realize PRP's therapeutic potential in ACL treatment,aiming to inform future studies and clinical practices.By understanding PRP's mechanisms of efficacy and identifying the most beneficial patient populations,PRP could significantly impact orthopaedics and sports medicine,improving recovery pathways and patient outcomes. 展开更多

Rec... In the traditional data envelopment analysis (DEA) structure, the efficiency score for one decision making unit (DMU) is calculated by measuring the distance of the evaluated DMU to the best practice frontier. Recent researches have provided the reasonability of considering the worst practice frontier as a supple- ment to the traditional DEA techniques. The existing researches take only one type of frontier into account, and they cannot com- pare the evaluated DMU with both the best and the worst perform- ing DMUs. A DEA-based procedure is developed to consider the best and the worst frontiers in the same scenario where the ratio of two distances (RDS) measure is proposed. The principal appli- cation of this approach is for ranking, and, as a complement tool, for performance evaluation. The proposed approach can be used in a wide range of applications such as the performance evaluation of employees and others. Finally, a bookstore data set is used to illustrate the proposed approach. 展开更多
