Abstract: 在“双碳”目标与“15分钟生活圈”建设背景下，共享电单车“停放难、调度难”问题日益凸显。本文提出一种圆柱体升降横移式立体车库方案，突破传统设备本位思路，融合立体空间与共享行为协同优化。通过结构设计、PLC控制与物联网平台集成，实现三层自动化存取与智能管理。该方案占地小、容量大，有效缓解地铁口停车压力，提升运营效率，满足城市短途接驳需求。
Under the “dual carbon” strategy and “15-minute living circle” initiative, the inefficient parking and dispatch of shared e-bikes have become major operational challenges. This paper proposes a cylindrical lift-and-shift multi-level parking garage, integrating spatial optimization with shared behavior. The three-tier structure, controlled by PLC and IoT, enables automated access and intelligent management. Compact yet high-capacity, the system alleviates parking congestion at subway stations and improves operational efficiency for urban short-distance transit.

As an important component of the green mobility system, shared e？bikes merit in？depth investigation regarding their adaptability and development strategies in mountainous cities. Based on trip order data and other relevant information from shared e？bikes in the central urban area of Chongqing, this study systematically analyses the current travel characteristics of shared e？bikes. The findings indicate that shared e？bikes primarily serve short？ to medium？distance trips, with pronounced commuting patterns on weekdays. Two typical usage scenarios are identified: rail transit connection and supplementation of public transport services within specific areas. Drawing on policy experiences from major cities across China, this paper proposes development strategies including zone？based moderate expansion, demand？oriented deployment, right？of？way optimization and retrofitting, and pilot demonstration projects. These strategies aim to provide reference for the scientific planning and orderly development of shared e？bikes in mountainous cities.
"The Dirt Bike and American Off-road Motorcycle Culture in the 1970s"
David W. Russell
International Journal of Motorcycle Studies , 2005,
Abstract: The 1960s were a time of dramatic change in America’s stated values, mores, and interests; of experimentation and expanding boundaries. As the 1960s passed into 1970, the availability of vast off-road areas, a lust for personal freedom, and the appearance of light-weight, purpose-built off-road motorcycles set the stage for a nationwide boom in off-road motorcycling. The author explores dirt bike design, 3 important phases of the 1970s dirt bike boom, American off-road motorcycling culture, and the beginnings and influence of the cultural voice of the movement—the irreverent, style-influencing, and comedic “DIRT BIKE Magazine”. The author concludes by examining who these Americans were, why they were drawn to the movement, and how the formative conditions enabling the movement changed over the decade.

Abstract: 在财务信息化高度发达的今日，企业财务管理面临着越来越复杂的挑战，传统的财务管理模式已无法满足现代企业高效、精细化管理的需求。财务共享服务中心(FSSC)作为一种新型的财务管理模式，逐渐成为众多电子商务企业的重要选择。选取拼多多、京东、阿里和苏宁等知名电商企业，结合企业案例分析提出借助于FSSC企业可进一步提高财务管理效率、优化财务管理流程以及提升财务分析能力。本文分析了FSSC在账务处理与核算、费用报销与管理、资金管理与支付、税务管理与合规以及预算编制与预测中的应用，研究了FSSC在企业财务管理应用中面对的问题，提出做好系统集成工作、加强人员技能培训、支持跨部门沟通等建议。
In today’s highly developed financial informatization, enterprise financial management is facing increasingly complex challenges, and traditional financial management models can no longer meet the needs of modern enterprises for efficient and refined management. Financial Shared Services Center (FSSC), as a new financial management model, has gradually become an important choice for many e-commerce enterprises. Selecting well-known e-commerce companies such as Pinduoduo, JD.com, Alibaba, and Suning, combined with enterprise case analysis, it is proposed that using FSSC enterprises can further improve financial management efficiency, optimize financial management processes, and enhance financial analysis capabilities. This paper analyzed the application of FSSC in accounting processing and accounting, expense reimbursement and management, fund management and payment, tax management and compliance, and budget preparation and forecasting, studied the problems faced by FSSC in enterprise financial management, and proposed suggestions such as doing a good job in system integration, strengthening personnel skills training, and supporting cross departmental communication.

Journal of Antennas (JA) , 2025, DOI: 10.12677/ja.2025.141001
Abstract: 针对卫星通信天线小型化、高增益、口径复用的需求，设计一种工作在Ku (12.25~12.75 GHz)、Ka (19.6~21.2 GHz)的新型双频段横电磁波线性源馈电网络。网络包含：采用级联E-T结构的波导功分器，对比H-T结构缩短了横向尺寸；含有直角结构扭波导的模式转换器，扭波导长度仅为四分之一波长，且对比现有锐、钝角结构更易加工；将两频段生成的线性源组合的双工器，实现天线辐射体的单端口双频激励。仿真结果显示，Ku/Ka频段反射系数均优于？22 dB，传输系数分别优于？0.18 dB、？0.1 dB，隔离度分别优于？36 dB、？40 dB，合成波电场幅度波动范围分别为±1.5 dB、±0.8 dB，相位波动范围分别为±10 ？、±8？。新型双频馈电网络幅度波动为双平行板馈电系统的15%，避免了能量的锥削分布；横向尺寸约为H-T馈电网络的50%，实现了结构的紧凑设计。
In response to the requirements of miniaturization, high gain, and aperture reuse of satellite communication antennas, a novel dual-band transverse electromagnetic wave linear source feeding network working in Ku (12.25~12.75 GHz) and Ka (19.6~21.2 GHz) bands is designed. The feeding network consists: a waveguide power divider that adopts a cascaded E-T structure that is shorter in the H-T lateral dimension; a mode converter containing a right twist waveguide that is easier to manufacture than acute or obtuse angle structures and is only one quarter of a wavelength in length; a duplexer that combines two sources generated in two frequency bands to achieve single-port dual-frequency excitation of an antenna radiator. The simulation results show that the reflection coefficients in the Ku/Ka frequency bands are better than ？22 dB, the transmission coefficients are better than ？0.18 dB and ？0.1 dB respectively, the isolation levels are better than ？36 dB and ？40 dB respectively, the amplitude fluctuation range of the synthesized wave electric field is ±1.5 dB and ±0.8 dB respectively, and the phase fluctuation range is ±10？ and ±8？ respectively. The amplitude fluctuation of the novel dual-frequency feed network without tapering is 15% of that of the dual parallel-plate feed system; its compact lateral size is approximately 50% of that of the H-T feed network.

ZooKeys , 2011, DOI: 10.3897/zookeys.150.2191
Abstract: Support systems play an important role for the communication between users and developers of software. We studied two support systems, an issues tracker and an email service available for Scratchpads, a Web 2.0 social networking tool that enables communities to build, share, manage and publish biodiversity information on the Web. Our aim was to identify co-learning opportunities between users and developers of the Scratchpad system by asking which support system was used by whom and for what type of questions. Our results show that issues tracker and emails cater to different user mentalities as well as different kind of questions and suggest ways to improve the support system as part of the development under the EU funded ViBRANT programme.
Comparing the imitative skills of children and nonhuman apes Comparaison des capacités d’imitation des enfants humains et des grands singes
Malinda Carpenter,Josep Call
Revue de Primatologie , 2009, DOI: 10.4000/primatologie.263
Abstract: We propose a framework which breaks down the mechanisms of social learning into their four constituent elements: actions, results, goals, and context. We review what is known about the use of each of these elements in children’s and apes’ social learning, with special attention to possible differences among apes with different rearing histories. We conclude that, by 12 months of age, human infants use each of the four elements when interpreting and selectively copying others’ behavior. Apes, on the other hand, appear to focus solely on the results of demonstrations (although there is some suggestive evidence that enculturated apes may copy actions and goals more than other apes). Finally, we show how these (and other related) findings can be explained by uniquely human skills and motivations for shared intentionality. Nous proposons ici de décomposer les mécanismes de l'apprentissage social en quatre éléments constitutifs : actions, résultats, objectifs et contexte. Nous passons en revue ce que l'on sait de l'utilisation de chacun de ces éléments au cours de l'apprentissage social chez les enfants humains et les grands singes, en prenant en compte les différents contextes d’élevage dans lesquels les grands singes ont pu se développer. Nous concluons qu'à 12 mois, les jeunes enfants emploient chacun des quatre éléments pour interpréter et copier sélectivement le comportement des autres. Les grands singes, eux, semblent se concentrer uniquement sur le résultat des démonstrations (bien qu'il y ait des preuves suggérant que des individus acculturés copieraient plus les actions et les objectifs des démonstrateurs que les autres individus). Finalement, nous montrons comment ces découvertes (et d'autres qui en découlent) peuvent être expliquées par le caractère unique des compétences humaines et la motivations des être humains à partager les intentions d’autrui.(Traduit par la Rédaction).

Abstract: 数字经济已成为驱动中国式现代化的重要引擎，深刻改变着社会生产和生活方式。共享发展理念作为共同富裕的核心内涵，强调发展成果由人民共享。在此背景下，以数字平台为载体的共享经济新业态，如社区团购与共享电商，成为践行共享发展理念的鲜活样本。本研究通过文献分析、机制剖解与案例归纳，旨在探究数字经济如何重塑共享发展的实现路径。研究发现，数字平台通过重构“技术–组织–分配”三维结构，催生出两种典型实践形态：社区团购依托邻里关系网络，呈现出“嵌入式共享”的特征，在提升消费效率的同时重构了邻近社会空间；共享电商则依托跨区域数据网络，呈现出“平台化共享”特征，在扩大机会公平的同时也面临收益分配不均等挑战。本文为理解与引导数字经济时代的共享发展实践提供了新的分析工具。
The digital economy has become an important engine driving Chinese-style modernization and profoundly transforming social production and lifestyles. As the core connotation of common prosperity, the concept of shared development emphasizes that the fruits of development are shared by the people. Against this background, new forms of sharing economy supported by digital platforms, such as community group buying and shared e-commerce, have become vivid examples of practicing the concept of shared development. Using literature analysis, mechanism interpretation and case induction, this study aims to explore how the digital economy reshapes the realization path of shared development. The study finds that digital platforms have given birth to two typical practical forms by reconstructing the three-dimensional structure of technology-organization-distribution. Relying on neighborhood networks, community group buying is characterized by “embedded sharing”, which improves consumption efficiency while reconstructing adjacent social spaces. Relying on cross-regional data networks, shared e-commerce is characterized by “platform-based sharing”, which expands equality of opportunity but also faces challenges such as uneven income distribution. This paper provides a new analytical tool for understanding and guiding the practice of shared development in the digital economy era.
