In the light of the fact that there has been substantial growth in China's exports in last three decades, particularly after China joined the WTO in 2001, this article investigates the major sources of China's export performance during 2002-2014 by using the constant market share (CMS) model. In this study, exports are further decomposed in three categories based on their technological intensity using Lail (2000) classification on 3 digit SITC Revision-3 data provided by UN Comtrade via WITS database. The categories are high technology, medium technology and low technology. It is found that growth of China's exports has, moreover, remained above world exports growth in all three categories during the period of study. The analysis reveals that export performance is mainly attributed to 让s competitive strength in the global market, though decreasing trend has been observed in the competitiveness of all three categories. Increasing cost of labor and appreciating RMB could be the causes behind decreasing competitiveness of Chinese exports. Product structure effect, on an average, has turned out to be negative in all the categories which is the most disturbing aspect of China's export performance. On the other hand, geographical structure effect has positive impact on export performance of high-technology based exports whereas it has negative impact on export performance of low-technology and medium-technology based exports. China being the world's largest exporter, decreasing competitiveness and wrong product structure effect could adversely influence its export performance in particular and its growth in general. 展开更多

A new T-shaped tunnel field-effect transistor(TTFET) with gate dielectric spacer(GDS) structure is proposed in this paper. To further studied the effects of GDS structure on the TTFET, detailed device characteristics such as current-voltage relationships, energy band diagrams, band-to-band tunneling(BTBT) rate and the magnitude of the electric field are investigated by using TCAD simulation. It is found that compared with conventional TTFET and TTFET with gate-drain overlap(GDO) structure, GDS-TTFET not only has the minimum ambipolar current but also can suppress the ambipolar current under a more extensive bias range. Furthermore, the analog/RF performances of GDS-TTFET are also investigated in terms of transconductance, gate-source capacitance, gate-drain capacitance, cutoff frequency, and gain bandwidth production. By inserting a low-κ spacer layer between the gate electrode and the gate dielectric, the GDS structure can effectively reduce parasitic capacitances between the gate and the source/drain, which leads to better performance in term of cutoff frequency and gain bandwidth production. Finally, the thickness of the gate dielectric spacer is optimized for better ambipolar current suppression and improved analog/RF performance. 展开更多

Reducing the influence of back-sputtering effect can effectively improve the accuracy of the measurement of the Hall thruster plume effect.Quartz crystal microbalance(QCM)was used to measure the deposition and sputtering distribution of HET-40 thruster plume on two different experimental conditions:case1,using liquid nitrogen heat sinks and case 2,without using liquid nitrogen heat sinks.Meanwhile,X-ray photoelectron spectroscopy(XPS)was used to analyze the composition of the QCM surface after two experiments.The results of the two experiments showed that the sputtering rate under the condition of case 1 was slightly higher than case 2.Especially within the range of 90°to 110°relative to the thruster axis,case 1 experiment result showed sputtering effect,while case 2 experiment showed deposition effect.Through analysis of the experimental results,it can be found that using liquid nitrogen heat sink to reduce the temperature of the inner wall surface of vacuum chamber can effectively adsorb the particles sputtered by the plume and reduce the concentration of back-sputtering particles,leading to the above phenomenon. 展开更多

This paper is devoted to binary stars belonging to the class of eclipsing-variable systems.Photometric and spectroscopic analysis of eclipses allows us to determine geometric parameters of the orbit and physical characteristics of stellar components as well as inclinations of stellar equators to the orbital plane.Estimations of inclinations can be obtained from measurement of the Rossiter-McLaughlin effect,which is discussed using examples of some eccentric binaries with an anomalous apsidal effect.Our task is to find the complete spectrum of solutions of the equation of apsidal motion,depending on the inclinations of the polar axes of the components to the orbital one for these systems,based on their individual spectroscopic and photometric observational data.The matrix of solutions allows us to select those pairs of polar inclinations that provide agreement with the observational apsidal period. 展开更多

Spin currents, which are excited in indium tin oxide(ITO)/yttrium iron garnet(YIG) by the methods of spin pumping and spin Seebeck effect, are investigated through the inverse spin Hall effect(ISHE). It is demonstrated that the ISHE voltage can be generated in ITO by spin pumping under both in-plane and out-of-plane magnetization configurations.Moreover, it is observed that the enhancement of spin Hall angle and interfacial spin mixing conductance can be achieved by an appropriate annealing process. However, the ISHE voltage is hardly seen in the presence of a longitudinal temperature gradient. The absence of the longitudinal spin Seebeck effect can be ascribed to the almost equal thermal conductivity of ITO and YIG and specific interface structure, or to the large negative temperature dependent spin mixing conductance. 展开更多

Under a logical self-consistent theoretical framework,this paper discusses SOEs’innovation efficiency and innovation conundrum facing Chinese local firms.By creating a theoretical model of endogenous technology level,this paper finds that credit discrimination and soft budget constraint have both a crowding out effect and compensatory effect on corporate innovation.When firms engage in less profitable innovation,the compensatory effect outweighs crowding out effect,and a higher share of SOEs will promote the overall level of innovation.On the contrary,when firms engage in more profitable innovation,the compensatory effect is smaller than crowding out effect,and a higher share of SOEs will diminish overall innovation.In this sense,SOE innovation exhibits a threshold characteristic.Then,this paper carries out an empirical test using the inter-provincial panel data of 1997-2013,which proves our assumption.Finally,this paper arrives at conclusions and policy implications. 展开更多

Objective: To evaluate the in vitro and in vivo effect of the Algerian propolis ethanolic extract(EEP) against Echinococcus granulosus(E. granulosus) infection. Methods: In vitro scolicidal activity of EEP was investigated on the protoscolices of hydatid cyst. This in vitro study was conducted by using an in vivo assay. BALB/c mice were inoculated with E. granulosus and treated with propolis for three months. Hydatid cysts development was assessed. Nitric oxide(NO), tumor necrosis factor alpha(TNF-α) production and inducible NO synthase, NF-κB, and TNF-α spleen expression were estimated by Griess method and immunofluorescence respectively.Results: Our study revealed that EEP has a high scolicidal activity against E. granulosus. Oral administration of EEP decreased TNF-α, NF-κB and inducible NO synthase expression in the spleen tissues in the CE+EEP group, in comparison with the CE group. Concomitantly, EEP treatment caused an important systemic decrease in NO and TNF-α levels. These findings are associated with the reduction of CE development. Conclusions: This is the first report demonstrating with interest the antihydatic and immunomodulatory effects of the Algerian EEP, suggesting its therapeutic potential for the hydatid disease treatment. 展开更多

Based on China’s industrial enterprises-customs matched data, this paper utilizes two-tier stochastic frontier analysis method to estimate and verify the extent to which selection effect and competition effect influence exporting firms’ markup. Our findings suggest that the interaction between selection effect and competition effect ultimately causes actual firm markup to be higher than the baseline markup by 7.11%. Exporting firms’ actual markup is higher than the baseline markup by different degrees. In terms of the decomposition of selection effect, TFP explains for 28.05% of selection effect, and nonproductivity factors explain for the rest 71.95%. By controlling for the type of firms’ export, the export-productivity paradox only exists for processing trade firms, which shows that with increasing trade facilitation, the policy incentives to encourage firms to export are major contributors to the low export markups. 展开更多

Serrated flow under the influence of electroplasticity in Al-Mg alloys is investigated within the dynamic strain aging interpretations of the Portevin-Le Chatelier effect. The stability of plastic region is extended by the pulsed electric current with the increase of critical strain and the extension of waiting time.Meanwhile, the dislocation density, affecting the plastic instabilities due to the interaction between solute atoms and mobile dislocations, is greatly reduced, which plays a dominant role in the suppression of serrated flow. 展开更多

A comprehensive exploration of the aminolysis mechanism for methyl indole-3-acetate with ammonia is carried out by employing the B3 LYP/6-311++G(d,p), M06-2 X/6-311++G(d,p) and MP2/6-311++G(d,p)//M06-2 X/6-311++G(d,p) levels. Two alterative reaction channels of the concerted and addition/elimination stepwise processes including the uncatalyzed, base-catalyzed reactions are taken into consideration. Subsequently, the substituent effects and solvent effects in methanol are also evaluated at the M06-2 X/6-311++G(d,p) level. The calculated results indicate that the calculated values of M06-2 X level are quite close to those of MP2, the stepwise pathway has more advantages to the concerted one for all of the reaction processes and the catalyst facilitates the proton migration and decreases the energy barriers as well. It is shown that the most preferred mechanism is the based-catalyzed stepwise process, the substituent of NH2 group slightly accelerates all the aminolysis reaction processes, and the solvent effect does not remarkably change the mechanism of the reaction. 展开更多
