Yuan-Chou Jing,Kun-Yung Chen 한국정밀공학회 2019 International Journal of Precision Engineering and Vol.20 No.4

The different state-error fitness functions (FFs) are proposed and compared numerically and experimentally to identify a motor-table system by using self-learning particle swarm optimization (SLPSO). Firstly, the completed mathematical model containing both of mechanical and electrical equations is successfully formulated. Secondly, the FFs containing different state-errors are compared by using PSO and SLPSO to identify the unknown parameters. It is found that the identify performance of the SLPSO algorithm by using FF with full-state error of displacement, velocity and current is the best than the other methods. Thus, the FF with full-state errors is adopted in experiments for a real mechatronic motor-table system. Then, the unknown parameters are successfully identified by the SLPSO algorithm. The contributions of this paper are: (1) the more states of the system are measured and used in the FF, the more parameters of system are accurately identified by the proposed identification approach, (2) the FF with full-state errors is performed in a real mechatronic motor-table system, and the unknown parameters are successfully identified by the SLPSO algorithm in experimental results.

The Study of China’s Military Strategy and Satellite Development: Moving Toward “Winning the Informationized War Globally”?

Yuan-Chou Jing 한국국방연구원 2019 The Korean Journal of Defense Analysis Vol.31 No.1

China’s military strategy has evolved across different leaders’ eras. Even though China’s military strategic guideline always stays on the track of “active defense,” the essence has been shifting from tradition to informationization. Since satellites are able to provide space information support so as to fulfill informationization, once informationization becomes the focus of military strategy, it is supposed to bring momentum to the research and development of satellites. Therefore, satellite development can be considered as an index to check whether the military strategy is being implemented or not. China is continuously making progress in satellite development. Especially since the informationization was included in the guideline in the Hu Jintao era, satellites started to be able to conduct space information support missions. In conclusion, China is sincerely fulfilling its military strategy through consistent satellite development. On the other hand, “local war” is another focus of strategic guidelines, it implies that China considers its national interests mainly concentrated on this region so far. However, while China’s interests are expanding globally, China will need to cultivate its global dominance based on rapid satellite development to safeguard the global interest; “Winning the informationized war globally” might be the next focus.

Mechanism analysis of traffic congestion at sag section of the tunnel

Yuan Jing,Wang Tao,Cui Fengying,Zhang Jing 한국물리학회 2022 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.81 No.8

Sag sections are segments of the expressway where the slope changes greatly from downward to upward. In the expressway networks, sag sections are usually the bottleneck of trafc. Sag sections have become an important inducement of trafc congestion for its special geometric characteristics. However, the intrinsic mechanism of trafc congestion on sag sections is still unclear, especially the congestion in the tunnels. To describe the trafc fow of diferent road conditions, a dynamic optimal velocity function is proposed. Then, coupled with the proposed function, a new lattice hydrodynamic model is developed to reveal the infuence of sag on the stability of trafc fow in the tunnel. The linear stability condition is further obtained to analyze the potential efects of sag on the dynamics of trafc fow. The modifed Korteweg-de Vrie (mKdV) equation is also derived by using perturbation theory, and the corresponding kink-antikink soliton solution is obtained. Finally, the evolution process of trafc fow during the sag section is demonstrated by numerical simulation. It is suggested that the downhill section sag worse the stability of trafc fow, while the uphill section could stabilize the trafc fow, which is consistent with the theoretical analysis well. In addition, we also study the evolution laws of density waves under diferent disturbances in the metastable region.

Chinese Nationalism and Sino-Japanese Realtions

Jing-Dong Yuan 인하대학교 국제관계연구소 2008 Pacific Focus Vol.23 No.2

Contemporary Chinese nationalism has its roots in the country’s nation-building and identity-forming movements in the late 19th and early 20th centuries that sought to establish China’s place in the community of nations. Today, nationalism in China can be characterized as falling into two major categories. On the one hand, there is nationalism embedded in patriotism with great pride in China’s civilization, major achievements, and confidence in the country’s future in embracing and meeting the challenges of globalization. On the other hand, there is the sentimental nationalism that reacts to what is perceived as injustice and insult done to China and has a strong victim mentality. The domestic discourse of nationalism can be influenced by government propaganda, intellectual debates, populous display of emotion and repulsion, or a mixture of all three. As China continues to grow in economic power and political influence, how nationalism is handled can have a significant impact on relations with its neighbors and beyond.

Muscle fatigue: general understanding and treatment

Jing-jing Wan,Zhen Qin,Peng-yuan Wang,Yang Sun,Xia Liu 생화학분자생물학회 2017 Experimental and molecular medicine Vol.49 No.-

Muscle fatigue is a common complaint in clinical practice. In humans, muscle fatigue can be defined as exercise-induced decrease in the ability to produce force. Here, to provide a general understanding and describe potential therapies for muscle fatigue, we summarize studies on muscle fatigue, including topics such as the sequence of events observed during force production, in vivo fatigue-site evaluation techniques, diagnostic markers and non-specific but effective treatments.

First-principles Study of the Electronic Structure of Nonmetal-doped Anatase TiO2

Yuan Wang,Jing Ma,Jian-Ping Zhou,Xiao-Ming Chen,Jing-Zhou Wang 한국물리학회 2016 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.68 No.3

In this paper, we present a detailed study of the structure, defect formation energy, and electronic and magnetic properties of nonmetal-doped TiO2 by using the first-principles projector augmented wave (PAW) potential within the generalized gradient approximation (GGA). The formation energy reduces with increasing electronegativity of the dopant. After doping with nonmetal elements, some band gaps of the doped-TiO2 become narrow, and others become wide, in which impurity states appear in the band gap. The relative positions of the impurity states are much different, mainly caused by the different electronegativities of the nonmetal elements F, O, B, C and N. When H is added to achieve a charge balance, the impurity states approach the valence band maximum, because the electronegativity difference among the nonmetal elements is decreased. Therefore, nonmetal and H codoping is an effective way to improve the visible-light catalytic activity of anatase TiO2. In addition, N-doping and C-doping can cause spin polarization of the TiO2 electronic structure and form 1.0 μB and 2.0 μB magnetic moment, respectively.

Canonical transient receptor potential channels and their modulators: biology, pharmacology and therapeutic potentials

Yuan-Yuan Gao,Wen Tian,Hui-Nan Zhang,Yang Sun,Jing-Ru Meng,Wei Cao,Xiao-Qiang Li 대한약학회 2021 Archives of Pharmacal Research Vol.44 No.4

Canonical transient receptor potential channels(TRPCs) are nonselective, high calcium permeability cationicchannels. The TRPCs family includes TRPC1, TRPC2,TRPC3, TRPC4, TRPC5, TRPC6, and TRPC7. These channelsare widely expressed in the cardiovascular and nervoussystems and exist in many other human tissues and celltypes, playing several crucial roles in the human physiologicaland pathological processes. Hence, the emergenceof TRPCs modulators can help investigate these channels’applications in health and disease. It is worth noting that theTRPCs subfamilies have structural and functional similarities,which presents a signifi cant diffi culty in screening anddiscovering of TRPCs modulators. In the past few years,only a limited number of selective modulators of TRPCswere detected; thus, additional research on more potent andmore selective TRPCs modulators is needed. The presentreview focuses on the striking desired therapeutic eff ectsof TRPCs modulators, which provides intel on the structuralmodifi cation of TRPCs modulators and further pharmacologicalresearch. Importantly, TRPCs modulators cansignifi cantly facilitate future studies of TRPCs and TRPCsrelated diseases.

Effects of contact shape on ballistic phonon transport in semiconductor nanowires

Jing-Jing Yao,Wei-Qing Huang,Gui-Fang Huang,Yuan Chen,Ling-Ling Wang,Wangyu Hu,Anlian Pan 한국물리학회 2012 Current Applied Physics Vol.12 No.2

We study the effects of contact shape on ballistic phonon transport in semiconductor nanowires at low temperatures using an approximative scalar model of continuum elasticity. Five different contacts connected to two semiconductor nanowires with different transverse widths are discussed. Numerical results show that the contact shape acts as an ‘acoustic impedance adaptor’, playing a crucial role on the ballistic phonon transmission and thermal conductance. The phonon coupling in the contacts with certain length facilitates ballistic phonon transmission compared to the abrupt interface, in which the phonon scattering is the strongest. It is found that the more the contact is abrupt, the smaller the thermal conductance is. The catenoidal contact rather than the abrupt interface is also the competitive candidate to obtain bigger thermal conductance. These results indicate that choosing an appropriate contact shape is one of the most critical factors to accurately measure the thermal conductance with a very high precision and reliability in different temperature ranges at low temperatures.
