This study aims to assess the efficacy of a tailored Tai Ji Quan intervention on gait kinematics for older Chinese women with knee OA.Methods: A randomized controlled trial involving 46 older women in Shanghai, China, with clinically diagnosed knee OA. Randomized(1:1)participants received either a 60 min Tai Ji Quan session(n = 23) 3 times weekly or a 60 min bi-weekly educational session(n = 23) for 24 weeks.Primary outcomes were changes in gait kinematic measures from baseline to 24 weeks. Secondary outcomes included changes in scores on the Western Ontario and Mc Master University Osteoarthritis Index(WOMAC) and Short Physical Performance Battery(SPPB).Results: After 24 weeks the Tai Ji Quan group demonstrated better performance in gait velocity(mean difference, 8.40 cm/s, p = 0.01), step length(mean difference, 3.52 cm, p = 0.004), initial contact angle(mean difference, 2.19°, p = 0.01), and maximal angle(mean difference, 2.61°,p = 0.003) of flexed knees during stance phase compared to the control group. In addition, the Tai Ji Quan group showed significant improvement in WOMAC scores(p < 0.01)(mean difference,-4.22 points in pain, p = 0.002;-2.41 points in stiffness, p < 0.001;-11.04 points in physical function, p = 0.006) and SPPB scores(mean difference, 1.22 points, p < 0.001).Conclusion: Among older Chinese women with knee OA, a tailored Tai Ji Quan intervention improved gait outcomes. The intervention also improved overall function as indexed by the WOMAC and SPPB. These results support the use of Tai Ji Quan for older Chinese adults with knee OA to both improve their functional mobility and reduce pain symptomatology.展开更多

The rat model was prepared by ligating the left anterior descending coronary artery. Electroacupuncture was performed at the left Neiguan(PC 6) for 20 min daily for 3 d. After the 3 rd time of the treatment, measurements of skin blood perfusion and temperature in Neiguan(PC 6) and Tianquan(PC 2) in all groups were made by laser speckle contrast imaging and infrared thermal image instrument. Real-time PCR and ELISA were used to measure m RNA level and protein level of α1-AR andβ2-AR in the skin tissues of Neiguan(PC 6) and Tianquan(PC 2), respectively. Serum levels of c Tn T and electrocardiogram were used to identify the state of myocardium.RESULTS: In the group receiving electroacupunture at Neiguan(PC 6), compared with control group,the skin temperature, blood perfusion, and β2-AR m RNA and protein level of model group significantly decreased(P < 0.05), α1-AR m RNA and protein level of model group significantly increased(P < 0.05);compared with model group, the skin temperature,blood perfusion, and β2-AR m RNA and protein level of L-EA significantly increased(P < 0.05), α1-AR m RNA and protein level of L-EA and H-EA significantly decreased(P < 0.05). The same trend has taken place in the former four groups of the Tianquan(PC 2).CONCLUSION: Low-or high-frequency electroacupuncture can improve the skin temperature and blood perfusion which may be induced by decreasingthelevelofα1-ARandincreasingthelevelofβ2-AR of the Neiguan(PC 6) and Tianquan(PC 2) in the rat with acute myocaidial ischemia.展开更多

Thispaper aimed to optimize the decentralization of management and exploitation of irrigation works for water users, organizations inQuan Lo-Phung Hiep irrigation system of Mekong River Delta. The research has implemented a survey on 384 water users alongfour canals of level 2 of Quan Lo-Phung Hiep irrigation system under two sets of index： （1） water users＇ perception assessment of theirrigation works （14 indicators） and （2） assessment of the management efficiency in the irrigation works （six indicators）. Theresearch proposes the decentralization process from building, After determining the correlation coefficients, the multi-objective linearregression equation will be shown on six single objective functions. With the aim at achieving the highest efficiency in themanagement and exploitation of the irrigation works, there should be a shift in terms of the water users＇ perception of the irrigationworks. These study results also demonstrate that about 65%-68% of the change in the indicators of the exploitation efficiency in theirrigation works is explained by some water users＇ perception indexes of irrigation works, including the quality of irrigation service andthe output efficiency in agricultural production. By using the algorithm for multi-objective optimization problem, the optimal results inperception are determined. The input data is generated for the matrix supporting the decision making, and the decentralization ofmanagement and exploitation of irrigation works meets the three criteria, i.e., effectiveness, sustainability and flexibility.展开更多

The chemical bonding is studied to discuss the relation between structrues and properties. Several classes of models in which there is no vacancy,one vacancy or two vacan-cies have been calculated. From the calculated results of bond or-der, a measure of covalent bond strength,and molecule orbital contour map, it is concluded that when Nb element added in-creases, the vacancies increase correspondingly,the covalent com-ponent of chemical bonds of the samples decreases -while the met-al-bonding component increases, so the hardness and resistance of the samples decrease.展开更多

Our main results demonstrate the QD luminescence results of photon emission show three distinctive regimes depending on the distance between QD and metallic nanowire, which elucidates a crossover passing from being metallic dissipative for much smaller emitter-nanowire distances to surface plasmon （SP） emission for larger separations at the vicinity of plasmonic metallic nanowire. Besides, our results also indicate that, for both the resonant case and the detuning case, through measuring QD emitter luminescence spectra and second-order correlation functions, the information about the QD emitter coupling to the SPs of the dissipative metallic nanowire can be extracted. This theoretical study will serve as an introduction to un- derstanding the nanoplasmonic imaging spectroscopy and pave a new way to realize the quantum information devices.展开更多

文摘This paper focuses on studying Lie symmetries and conserved quantities of discrete nonholonomic Hamiltonian systems. Firstly, the discrete generalized Hamiltonian canonical equations and discrete energy equation of nonholonomic Hamiltonian systems are derived from discrete Hamiltonian action. Secondly, the determining equations and structure equation of Lie symmetry of the system are obtained. Thirdly, the Lie theorems and the conservation quantities are given for the discrete nonholonomic Hamiltonian systems. Finally, an example is discussed to illustrate the application of the results.
文摘Nb-doped TiC ceramic,or (NbyTi1-y) Cx,in which amount of Nb element added is increased from zero to 40Wt. %, synthisized -with self-propagating high temperature synthesis,is studied with SCF-Xa-DV,a quantum chemistry cal-culating method. The chemical bonding is studied to discuss the relation between structrues and properties. Several classes of models in which there is no vacancy,one vacancy or two vacan-cies have been calculated. From the calculated results of bond or-der, a measure of covalent bond strength,and molecule orbital contour map, it is concluded that when Nb element added in-creases, the vacancies increase correspondingly,the covalent com-ponent of chemical bonds of the samples decreases -while the met-al-bonding component increases, so the hardness and resistance of the samples decrease.

文摘Motivated by the recent pioneering advances on nanoscale plasmonics and also nanophotonics tech- nology based on the surface plasmons （SPs）, in this work, we give a master equation model in the Lindblad form and investigate the quantum optical properties of single quantum dot （QD） emitter coupled to the SPs of a metallic nanowire. Our main results demonstrate the QD luminescence results of photon emission show three distinctive regimes depending on the distance between QD and metallic nanowire, which elucidates a crossover passing from being metallic dissipative for much smaller emitter-nanowire distances to surface plasmon （SP） emission for larger separations at the vicinity of plasmonic metallic nanowire. Besides, our results also indicate that, for both the resonant case and the detuning case, through measuring QD emitter luminescence spectra and second-order correlation functions, the information about the QD emitter coupling to the SPs of the dissipative metallic nanowire can be extracted. This theoretical study will serve as an introduction to un- derstanding the nanoplasmonic imaging spectroscopy and pave a new way to realize the quantum information devices.
