A novel underactuated finger mechanism was designed. Finger mechanism was incorporated into a humanoid robot hand to obtain more degrees of freedom with less actuators and good grasping functions with shape adaptation, therefore decreasing the requirements for the control system. A novel superunderactuated multifingered hand (TH-2 Hand) for a humanoid robot was designed based on a previous underactuated finger mechanism. The TH-2 Hand was attached to a humanoid robot because of its high personification, superunderactuation, compactness, easy real-time control, small volume, light weight, and strong grasping function.

Traces and echoes of De Architectura by Marcus Vitruvius Pollio in the work of Xu Guangqi in 17th

This study aims to investigate the role played by Xu Guangqi (1562–1633), minister of the Ming Dynasty, in the development of European scientific and technical knowledge in China between the 16th and 17th centuries by analyzing a book of Western technology that he wrote, namely, Taixi Shuifa (On Western Hydraulics). Several Western books related to machine knowledge are searched to trace the source of the illustrations in Taixi Shuifa. We found that Archimedes’ screw and Ctesibius’ machine, which are included in Vitruvius’ De Architectura volumes, also appear in the work of Xu Guangqi.

Rolling-element bearings in China: From ancient times to the 20th century
Lie SUN,Ang LI
《机械工程前沿(英文)》 2016年 第11卷 第1期 页码 33-43 doi: 10.1007/s11465-016-0373-2
The development of rolling-element bearings in China has spanned a long period. Based on several typical and important cases, the present article reconstructs the history of rolling-element bearings in China by dividing it into four stages according to the various characteristics of the bearings. The first stage represents the origin of rolling bearings in China, which remains controversial because of several suspected races and cages that were likely the components of bearings more than a millennium ago. At the second stage, a type of simple roller bearing was used for astronomical instruments not later than the 13th century based on clear philological and physical evidence. A similar bearing was also applied to an abridged armillary in the 17th century. Another type of spherical thrust bearings with rolling elements, which is a key component of a traditional Chinese windmill, could support a rotating shaft that moves rotationally and at an angle. At the third stage, the Chinese began studying and using the so-called European-style bearing since the 17th century. Moreover, over the last 100 years, the modern rolling bearing industry was gradually established in China, particularly because of the technology transfer from the Soviet Union in the 1950s. At the fourth stage, the Chinese government initiated the relatively rapid development of bearing technology. The government launched the “bearing movement” from the 1950s to the 1960s to establish the modern bearing industry and to promote rolling bearings as replacement for traditional sliding bearings. Furthermore, a number of large professional factories and institutions in China have continually introduced advanced technology and equipment. At present, these companies and institutions play a significant role in the international bearing industry.

Th17 Cells in autoimmune diseases
null
《医学前沿(英文)》 2015年 第9卷 第1期 页码 10-19 doi: 10.1007/s11684-015-0388-9
Th17 cells are a new subset of CD4+ T cells involved in the clearance of extracellular pathogens and fungi. Accumulating evidence suggests that Th17 cells and their signature cytokines have a pivotal role in the pathogenesis of multiple autoimmune-mediated inflammatory diseases. Here, we summarize recent research progress on Th17 function in the development and pathogenesis of autoimmune diseases. We also propose to identify new small molecule compounds to manipulate Th17 function for potential therapeutic application to treat human autoimmune diseases, including rheumatoid arthritis, systemic lupus erythematosus, Sj?gren’s syndrome, inflammatory bowel disease, and multiple sclerosis.
