Core Viewpoint - The "2025 Beijing Cultural Forum" focuses on the innovative application of digital technology in the protection and inheritance of cultural heritage, aiming to provide new solutions for the transmission of human civilization [1][6]. Group 1: Digital Technology in Cultural Heritage - Digital technology enhances the clarity and completeness of cultural heritage management, acting as a "guardian" for artifacts and improving archaeological and historical research capabilities [3][9]. - The use of virtual reality and interactive technologies in smart museums creates immersive exhibition spaces, with 12,000 online exhibitions planned for 2024, offering continuous cultural services to the public [3][6]. Group 2: Global Collaboration and Innovations - Experts from various countries presented their experiences, such as the application of satellite remote sensing and radar technology in archaeological site analysis [3][6]. - The forum highlighted successful digital preservation projects, including the digitization of 195,000 artifacts in the Palace Museum and over 500 terabytes of data from the Dunhuang Academy [6][9]. Group 3: Future of Cultural Heritage - A roundtable discussion emphasized the role of digital technologies like 3D imaging, digital twins, and generative AI in enhancing the protection and management of cultural heritage while ensuring safety and public service [7][9]. - The forum called for open collaboration in cultural heritage protection actions and the establishment of a global digital display platform for important cultural heritage resources [9].

Core Viewpoint - The article discusses the increasing accessibility and adoption of advanced automotive technologies, particularly rear-wheel steering, which was once exclusive to high-end luxury and performance vehicles. Group 1: Technology Accessibility - Many high-end features that were once exclusive to luxury vehicles are now becoming standard in various models, including electric vehicles [1][2] - Technologies such as air suspension and advanced driving assistance systems have seen significant growth in recent years [2] Group 2: Rear-Wheel Steering - Rear-wheel steering, previously found in high-end models like Porsche 911 and Lamborghini Aventador, is now being standard in many domestic electric vehicles at lower price points [5][7] - Examples include models like the Tengshi N9 and Xiaopeng X9, which offer rear-wheel steering at prices around 400,000 and 300,000 respectively, with some models even exceeding 200,000 [8][10] Group 3: Benefits of Rear-Wheel Steering - Rear-wheel steering significantly enhances maneuverability, allowing larger vehicles to have a turning radius comparable to smaller cars, improving parking and navigation in tight spaces [10][13] - The technology also enables advanced features like crab walking, which relies on rear-wheel steering [14] Group 4: Market Penetration and Challenges - Despite its advantages, rear-wheel steering has a low global penetration rate of only 1.2%, indicating limited adoption compared to other technologies [17] - The complexity and cost of implementing rear-wheel steering systems, along with the need for additional space and maintenance considerations, hinder widespread adoption [53][67] Group 5: Historical Context and Evolution - The evolution of rear-wheel steering began in the late 19th century, with early attempts using simple mechanical systems, leading to its application in agricultural and military vehicles during the 20th century [18][22][24] - The transition to passenger vehicles occurred in the late 20th century, but early systems were passive and had reliability issues, prompting the development of more advanced active systems [29][32] Group 6: Future Prospects - Despite current challenges, domestic companies are investing in rear-wheel steering technology, which may lead to increased accessibility and innovation in the future [70][72] - The potential for domestic suppliers to disrupt the market and drive down costs is highlighted, suggesting a promising outlook for the technology's adoption [72][73]
