Essay | Discuss the transformative impact of additive manufacturing on healthcare, focusing on its role in creating personalized implants, prosthetics, and its potential for regenerative medicine. How does precise control over internal structures contribute to these advancements?

AM involves the layer-by-layer deposition of materials to build three-dimensional components. These components are typically designed using computer-aided design (CAD) models [50]. The ability to fabricate intricate structures with restricted geometries, which are unachievable through subtractive processes, is a distinctive advantage this technology offers [51]. Rapid prototype modeling extensively utilizes this technology [52]. By enabling rapid mock-up fabrication, it expedites the assessment of a concept quickly and efficiently. Rapid prototyping can be iterated multiple times until the component fulfills various requirements, such as cost-effectiveness, compliance, and user needs. With remarkable developments, additive manufacturing, or 3D printing, has moved beyond simple prototyping to create intricate and valuable finished goods. The range of applications for additive manufacturing has increased as high-performance metals, polymers, and biocompatible materials become more widely available. Due to its capacity to produce complex designs, cut waste, and speed up production, this technology has the potential to revolutionize sectors like aerospace, healthcare, automotive manufacturing, and consumer goods.

Precision control over internal structures made possible by additive manufacturing makes creating porous materials and specialized scaffolds for tissue engineering and regenerative medicine easier. Additionally, it makes it possible to produce lightweight engineering structures with complex geometries, enhancing productivity and performance in industries like the automotive.

Evaluate the significance of offshore wind in transforming China's energy landscape.

This study estimated offshore wind energy potential and power generation in China, aiming to evaluate the potential reduction in CO₂ emissions by replacing coal-fired electricity with clean wind power. The overall offshore wind power density is high, with particularly strong generation potential along the southern and eastern coasts. Theoretically, the power generation capacity within China’s Exclusive Economic Zone (EEZ) far surpasses the country’s current electricity consumption. Offshore wind energy can play a crucial role in increasing the share of clean energy in China’s power system in the future. Although its current utilization remains limited, planned offshore wind projects are expected to expand rapidly along the coast, significantly contributing to the nation’s carbon neutrality goals and the decarbonization of the power sector by reducing emissions in electricity grids.

However, further research is urgently needed to assess the feasibility of offshore wind farm development, taking into account economic, environmental, and ecological costs. Additionally, it is crucial to evaluate the potential contribution of emission reductions to the development of a regional low-carbon energy system.

Essay | Please describe the spatial rigid body mechanics analytical method introduced in the paper for analyzing human-machine contact force. Discuss its key components, such as the equivalent models and the considerations for establishing the equivalent human-machine contact force model. Highlight the significance of this method in understanding and optimizing human-machine interactions.

Compared with the traditional human-machine contact force model, the model proposed in this paper can well reflect the magnitude of the contact force in the six-dimensional space through a simple matrix, which greatly reduces the complexity of the algorithm. In addition, through introducing the screw theory, the internal force generated by the virtual branch under external load is solved, and the experiment is conducted by introducing a thin-film pressure sensor. This paper established the mapping relationship between external load and contact force effectively, providing an theoretical basis for improving human-computer interaction force effectively. This paper lays a foundation for improving human-machine cooperative movement.

. However, there still exist a certain deviation between the actual and theoretical values, so it is necessary to constantly calibrate the model. During the human-machine cooperative motion, the sensor in this paper is relatively susceptible to disturbance caused by changes in the external environment. Therefore, we will conduct in-depth research on the stability and robustness of the sensor in the future.
