Vision-Radar Fusion for UAV Perception in Low-Altitude Emergency Rescue: A Survey
type: item
description: Unmanned Aerial Vehicles (UAVs) have emerged as critical tools in emergency rescue operations, particularly in urban low-altitude complex environments characterized by dynamic obstacles, adverse weather, and signal interference. However, traditional single-modality perception systems, reliant on either vision or radar, struggle with limitations such as motion blur, low light conditions, and occlusion, compromising detection accuracy and navigation safety. This survey provides a comprehensive review of vision-radar fusion perception systems tailored for UAVs in such scenarios. We first examine advancements in image quality enhancement techniques, including diffusion models and super-resolution methods like SRGAN and ESRGAN , which address degradation in low-altitude imagery. Next, we explore multi-target detection and recognition via multi-modal fusion frameworks, such as Faster R-CNN-based approaches and cross-view spatial fusion. We then discuss robust multi-target tracking and trajectory prediction, highlighting graph neural networks (GNNs) and Transformer-based models like TrackFormer and MOTR . Finally, we cover low-altitude environment assessment and autonomous path planning, leveraging graph theory, 3D risk mapping, and deep reinforcement learning (e.g., MADDPG). By synthesizing global research trends, challenges like spatio-temporal alignment and real-time processing, and future directions toward end-to-end multi-modal integration, this review underscores the potential of fusion systems to enhance UAV resilience and efficiency in rescue missions. Our analysis reveals a clear trajectory toward AI-driven, adaptive perception, with implications for urban safety and disaster response.

The State of Enterprise-Level AI Commercialization in China: Insights from 2025 Trends and Global Comparisons
type: item
description: The rapid advancement of artificial intelligence (AI) technologies has positioned China as a global frontrunner in AI development, yet the commercialization of enterprise-level AI remains a critical challenge amid evolving policy landscapes, international competition, and market dynamics. This survey synthesizes empirical data from the 2025 China Enterprise-Level AI Commercialization Progress Report, based on a mixed-methods survey of 229 enterprises (81.6% SaaS vendors, 15.4% AI-native firms), with complementary insights from global benchmarks such as the Stanford HAI AI Index 2025 and the World Economic Forum's Blueprint to Action on China's AI-Powered Industry Transformation 2025. Key findings highlight a "scale exploration phase" in commercialization, where AI penetration exceeds 70% in internal operations but value realization is fragmented, with only 31.4% of firms achieving mature expansion. Structural divergences emerge between SaaS firms, which dominate market breadth through incremental "+AI" integrations, and AI-native entities pursuing disruptive "AI+" reconstructions, amid regional concentration in five major hubs (Beijing, Shanghai, Shenzhen, Hangzhou, Guangzhou) capturing 70% of resources. Challenges include demand-side bottlenecks like fragmented scenarios (29.7-30% cited as primary barriers) and low client penetration (54.5% below 10%), while trends point to vertical specialization, value-based pricing, and ecosystem integration as growth engines. Comparative analysis with MERICS' Report on China's AI Stack and RAND's analysis of China's AI industrial policy reveals China's shift toward self-reliant stacks (e.g., Huawei Ascend chips) and policy-driven innovation, contrasting U.S. capital-intensive models where private AI investment reached $109.1 billion in 2024 versus China's $9.3 billion . Contributions include a synthesized framework for assessing commercialization maturity, identification of eight core insights (e.g., organizational readiness as…

type: item
description: Unmanned aerial vehicles (UAVs) equipped with long-endurance remote sensing capabilities have revolutionized applications in economic development, national defense, emergency response, and disaster monitoring. However, traditional centralized processing paradigms suffer from high latency, resource inefficiency, and poor adaptability to dynamic low-altitude environments. This survey reviews advancements in multimodal large models (MLMs) for precise detection and perception in complex low-altitude scenarios, emphasizing three core challenges: enhancing intelligent terminal perception for adaptive learning, bolstering multi-UAV collaborative coverage through federated evolution, and achieving high-fidelity 3D perception via multimodal fusion. We synthesize recent developments in self-evolving online learning frameworks, asynchronous distributed federated optimization, and Transformer-based MLMs tailored for heterogeneous sensor data (e.g., LiDAR and multi-view cameras). Key contributions include a taxonomy of adaptive algorithms mitigating catastrophic forgetting and data heterogeneity, alongside benchmarks for edge deployment in resource-constrained UAV systems. By highlighting gaps in unsupervised multimodal alignment and real-time scalability, this work outlines future directions toward autonomous, resilient UAV swarms, fostering innovations in edge intelligence for spatial information technologies.

Consumption Trends in Science and Technology-Based Anti-Aging Products Among Oriental Women: A Systematic Review
type: item
description: The global anti-aging industry has witnessed exponential growth, driven by demographic shifts, technological advancements, and evolving consumer preferences, particularly in emerging markets like Asia. This survey paper synthesizes extant literature on consumption trends in science and technology-based anti-aging products among Oriental women, with a focal emphasis on East Asian demographics (primarily Chinese, Japanese, and Korean populations). Drawing on the seminal 2025 report by Yicai Business School and Baique Ling, which projects China's anti-aging market to exceed 1,500 billion CNY by 2026 at a 13.3% compound annual growth rate (CAGR), we integrate empirical findings from over 50 peer-reviewed studies spanning 2010–2025 to critically analyze market dynamics, consumer behaviors, and innovation trajectories. Key themes include the declining market concentration favoring domestic brands, heightened awareness of skin aging triggers such as unhealthy sleep patterns among 30–40-year-olds, and preferences for biotech ingredients like boswellic acid (Pro-Xylane) and collagen. We employ a systematic review methodology adhering to PRISMA guidelines, incorporating quantitative syntheses (e.g., meta-analyses of preference data) and qualitative thematic analyses to address gaps in prior Western-centric surveys. Findings reveal that Oriental women prioritize efficacy over brand loyalty, with over 70% favoring international premium products yet showing increasing adoption of tech-infused formulations. Sensitive skin subgroups, comprising 58.3% mild cases, demand milder, targeted innovations. Theoretical contributions extend the Theory of Planned Behavior to cultural contexts, elucidating how lifestyle factors mediate consumption. Practical implications for marketers include strategies for R&D collaborations and digital marketing integrations. Future directions propose longitudinal studies on AI-personalized anti-aging and cross-cultural comparisons. This synthesis underscor…

Advances in Cross-Source Intelligent Security Monitoring and Resilience Strategies for Urban Cyber-Physical Power Systems: A Comprehensive Review
type: item
description: The rapid integration of cyber-physical systems (CPS) into power grids has transformed traditional electricity networks into cyber-physical power systems (CPPS), enhancing efficiency but introducing profound cybersecurity vulnerabilities. Coordinated cyber-physical attacks, cascading failures, and information asymmetry exacerbate risks, as evidenced by incidents like the 2019 Venezuela blackout and disruptions during the Russia-Ukraine conflict. This review synthesizes advancements in cross-source intelligent security monitoring and analysis for power systems, focusing on urban CPPS models. Key technologies examined include multi-source log data aggregation for topology modeling, anomaly detection via self-supervised contrastive learning for missing node identification, tri-level optimization defenses against coordinated attacks, and vulnerability assessments using spectral metrics. We further discuss fault recovery strategies incorporating information delay models and graph convolutional networks (GCN) for optimal repair paths. Innovations such as multi-functional module integration (monitoring, powering, control) and asymmetric topology-aware attacks address gaps in high-security urban cores. By evaluating resilience metrics like load loss rates and islanding efficacy [35], this paper highlights pathways to enhance grid robustness, reduce outage costs, and support smart grid evolution. Future directions emphasize scalable AI-driven platforms for real-time threat mitigation, offering a comprehensive framework for researchers and engineers to bolster CPPS resilience.

A Unified Spatio-Temporal Data Organization Model for Forest and Grassland Resources Based on GeoSOT Encoding
type: item
description: The efficient integration, management, and application of multi-source heterogeneous spatio-temporal data remain a critical challenge in forest and grassland ecological informatics. Traditional GIS-based approaches often suffer from limited scalability, poor adaptability to diverse data modalities, and inadequate support for time-space linkage. To address these limitations, this study proposes a novel spatio-temporal data organization model based on the Geographical Subdivision Grid with One-dimension-integer on Two to n-th power (GeoSOT) encoding framework. We introduce a unified three-domain identifier—composed of spatial code, temporal stamp, and semantic attributes—to support fine-grained partitioning and indexing of both structured (e.g., vector, raster) and unstructured (e.g., video, sensor logs, text) data. The organization model employs multi-level GeoSOT grid cells as spatial anchors, integrating temporal semantics and object-level identifiers to form a one-code-per-element schema, ensuring the uniqueness and traceability of each data entity. A prototype system was implemented using forest resource and fire monitoring datasets from the Asia-Pacific Forestry Center. Comprehensive experiments demonstrate that the proposed model significantly improves data fusion flexibility, retrieval efficiency, and query precision compared to conventional spatial database models. Moreover, the system enables scalable and interactive spatio-temporal queries across multi-modal data sources. This study contributes a generalized, extensible, and semantically rich data organization framework that bridges spatial and temporal dimensions in forest and grassland applications. It holds promise for large-scale ecological monitoring, forest fire early warning, and smart forestry governance. Future work will focus on extending the model to real-time streaming data and integrating intelligent analytics for enhanced decision support.

Actor-Critic Convolutional Neural Network-Based Centralized Computation Offloading for Vehicular Edge Networks
type: item
description: Efficient computation offloading is essential for addressing the growing demand for low-latency, computation-intensive applications in vehicular edge networks. Existing approaches, including traditional optimization techniques and reinforcement learning-based methods, often struggle to cope with the highly dynamic network environments and the complex task dependencies characterized by Directed Acyclic Graphs (DAGs). To address these challenges, this paper proposes a novel centralized Actor-Critic Convolutional Neural Network-based Offloading Computation (ACCOC) algorithm. By leveraging the Actor-Critic framework enhanced with convolutional layers, ACCOC efficiently handles high-dimensional task offloading decisions, balancing delay and energy consumption under dynamic network conditions. The proposed algorithm is evaluated in a realistic vehicular edge computing environment with varying numbers of users, bandwidth availability, and edge server computational capabilities. Simulation results reveal that ACCOC achieves superior performance compared to baseline methods, including a non-convolutional Actor-Critic algorithm, Deep Q-Network (DQN), and random or fully local execution strategies. Specifically, ACCOC demonstrates faster convergence and higher system utility, achieving an average reward of 0.78 compared to 0.72 for the non-convolutional baseline. Furthermore, the algorithm maintains robust performance across diverse parameter settings, highlighting its scalability and adaptability.

Advancing Smart Supply Chain Security Through Digital Twin Technology
type: item
description: In the global context of combating COVID-19, the complexity and demands associated with supply chain security have significantly intensified. Moving forward, the innovation and advancement of supply chain security will increasingly reflect the evolving requirements of global economic activities. The integration of digital twin technology promises to usher in a new era of intelligent supply chain security. This technology facilitates the complete digital representation of supply chain security by leveraging advancements in technology, centralized information management, and standardized rule formulation. Unlike the physical world, the virtual realm created by digital twins operates without the constraints of spatial distance, where distance serves merely as a reference rather than a barrier influenced by time zones. The virtual environment, being a folded space, allows for real-time observation and control interventions regardless of the physical separation between points A and B, provided digital twin technology is employed. Consequently, future smart supply chain security should be represented and validated through digital simulation models grounded in digital twin technology.

A Novel Distributed ADMM Method in Large-Scale Applications
type: item
description: Stochastic alternating direction method of multiplier (ADMM) has shown great promise in distributed environments, and improvements in algorithmic flexibility are expected to result in significant advantages. In this paper, we provide Flex-SADMM, a novel stochastic optimization method based on distributed ADMM. To address the subproblems of ADMM, we specifically integrate variance-reduced first-order information and approximate second-order information in order to achieve steady convergence and improve the search direction's precision. Moreover, in contrast to other ADMM-based approaches that require updates from every computational node in each iteration, our framework only requires nodes to update once, at a predetermined iteration interval, greatly increasing flexibility. Experiments validate the effectiveness and improved flexibility of our suggested approach.

Incremental Cubic Regularized SR1 Quasi-Newton Method and the Applications in Large-Scale Problems
type: item
description: This paper delves into an innovative incremental cubic regularized symmetric rank-1(SR1)method (ICuREG-SR1). By incorporating the cubic regularization technique into SR1,we successfully address the issue of indefinite resulting matrix in SR1. Our core strategy is to adopt an incremental optimization scheme, gradually updating the information of the objective function,which typically involves a sum of multiple independent functions, and is very common in large-scale machine learning tasks. Through numerical experiments on multiple machine learning problems,we find that compared with other traditional algorithms, our proposed algorithm exhibits superior performance in terms of gradient magnitude.
