Abstract: Since 1978 , labor income share in China has declined rapidly with drastic economic growth rate . This paper decomposes the labor income sharein theindustrial sector and finds that the movement of the industrial structure is part of the reason for the declining labor income share .We alsoanalyze theeffects of trade ,technology progress and state-owned monopolypower by using the production cost model . It indicates that technology upgrading and decrease of monopoly power will impose a decrease on labor income share .Ceteris paribus ,the coefficient of import penetration rate in the trade variables is positive and significant . Regression in different stages shows that the change of trade mode is the main reason for the declining labor income share .In the time of import-export related processing trade in the Pearl River Delta , import penetration rates promote labor demand and thus raise the labor income share .While in the time of import-oriented processing trade in the Yangtze River Delta , the simultaneous decline of 5 import penetration rate and labor income share is the result of lowering raw material and labor cost from profit maximizing enterprises . Therefore ,import penetration has different mechanisms on labor income share in different stages .

Abstract: 始自20世纪80年代中期的财政体制改革对中国经济增长起到重要作用.财政分权是财政改革中上下级政府财政权力分配的测度.从省级以下层面看,财政分权对区域经济增长起到了显著的推动作用.以1985-2006年省级以下市(县)的面板数据进行回归得出的结果表明,财政分权从中央集中控制向完全分权的财政制度转变,将使经济增长率提高9.2个百分点.1994年实行的分税制改革是显著区别于先前诸如财政分成和财政包干的改革,是财政体制改革的重要阶段,它更有利于加速经济增长.财政分权的正效应并不是通过增加政府支出和私人投资所得的,而是使政府支出和私人投资用于效率更高的地方,从而实现经济增长.

Abstract: The wettability and bonding in Ni/Ti(C, N) systems with multiple carbide additions were studied by sessile drop technique and vacuum brazing technique, respectively. The phase characterizations of substrates and fracture surfaces were conducted by XRD. The microstructures at metal/ceramic interfaces and fracture surfaces were observed via SEM in back scattered mode and second electron mode, respectively. Furthermore, an X-ray energy-dispersive spectrometer (EDS) attached to SEM was used to study the elements diffusion in interfacial regions. The results reveal that diffusion and dissolution mechanism controlled reactive wetting takes place in the system in high temperature wetting. Results also show that the contact angles decrease with multiple carbide additions, and the effect of multiple carbide additions is stronger than that of single additions. The contact angle reaches the lowest value in the lowest TiC content case. The enhancement of the wettability is due to alloying procedure during high temperature wetting when metallic atoms diffuse into Ni phase, which decreases the interfacial energy of Ni/Ti(C, N) systems. The bonding results show that the interfacial bonding strength is higher than that of solid solutions, that makes most of the specimens fail in ceramics matrix.

Abstract: Economists have paid their great attentions to the macroeconomics research under open economy.In this paper, we made such variables as aggregate supply of products,money supply and wage endogenous.Based on the dornbusch model, we establish the disequilibrium models including such variables as exchange rate, price, foreign asset and wage. Finally, we give the stability conditions for the models.
Application of Transaction Mining Based on FP-Table Algorithm in Mobile Electricity Market  [PDF]
Chuncheng Gao, Yong Dai, Minghai Jiao
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.37014
Abstract:

Electricity market trade based on mobile intelligent device will extend the volume of transaction. For the massive and various trading data, transaction mining algorithm is very useful to find the relationship of correlative elements such as trade price and power capacity, and it always occurs between the power users and power generation enterprises. The novel FP-Table algorithm is proposed in this paper to solve the massive transaction mining problem. The FP-Table algorithm integrates the Hash table into FP-Growth algorithm, using two-dimension table saving frequency count of item pair, then mining the frequency items of electricity transactions efficiently. Application of mobile transaction mining is proved to be high efficiency and high value by performance experiment results.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0035881
Abstract: Background Previous studies suggested that the molecular subtypes were strongly associated with sentinel lymph node (SLN) status. The purpose of this study was to determine whether molecular subtype classification was associated with non-sentinel lymph nodes (NSLN) metastasis in patients with a positive SLN. Methodology and Principal Findings Between January 2001 and March 2011, a total of 130 patients with a positive SLN were recruited. All these patients underwent a complete axillary lymph node dissection. The univariate and multivariate analyses of NSLN metastasis were performed. In univariate and multivariate analyses, large tumor size, macrometastasis and high tumor grade were all significant risk factors of NSLN metastasis in patients with a positive SLN. In univariate analysis, luminal B subgroup showed higher rate of NSLN metastasis than other subgroup (P = 0.027). When other variables were adjusted in multivariate analysis, the molecular subtype classification was a determinant of NSLN metastasis. Relative to triple negative subgroup, both luminal A (P = 0.047) and luminal B (P = 0.010) subgroups showed a higher risk of NSLN metastasis. Otherwise, HER2 over-expression subgroup did not have a higher risk than triple negative subgroup (P = 0.183). The area under the curve (AUC) value was 0.8095 for the Cambridge model. When molecular subtype classification was added to the Cambridge model, the AUC value was 0.8475. Conclusions Except for other factors, molecular subtype classification was a determinant of NSLN metastasis in patients with a positive SLN. The predictive accuracy of mathematical models including molecular subtype should be determined in the future.

Abstract: Background The exact lymphatic drainage pattern of the breast hasn't been explained clearly. The aim of this study was to investigate the sentinel lymphatic channels (SLCs) in the cancerous breast. Whether the type of SLCs influenced the detection rate and false-negative rate of SLNB was also assessed. Methodology and Principal Findings Mimic SLNB was performed in 110 early-stage breast cancer patients with subareolar injection of blue methylene dye intraoperatively. Postoperatively, 110 specimens of modified radical mastectomy were examined for all blue SLCs after additional injection of methylene dye in peritumoral parenchyma. Interestingly, three types of SLCs, including superficial sentinel lymphatic channel (SSLC), deep sentinel lymphatic channel (DSLC), and penetrating sentinel lymphatic channel (PSLC) were found in 107 patients. Six lymphatic drainage patterns based on the three types of SLCs were observed in these 107 patients. The proportions of the drainage pattern SSLC, DSLC, PSLC, SSLC+DSLC, SSLC+PSLC, and DSLC+PSLC in the breast were 43%, 0.9%, 15.9%, 33.6%, 3.7% and 2.8%, respectively. The lymphatic drainage pattern in the breast was a significant risk factor for unsuccessful identification of sentinel lymph nodes (P<0.001) and false-negatives in SLNB (P = 0.034) with the subareolar injection technique. Conclusions Three kinds of SLCs are the basis of six lymphatic drainage patterns from the breast to the axilla. The type of SLCs is the factor influencing the detection rate and false-negative rate of SLNB. These findings suggest the optimal injection technique of the combination of superficial and deep injection in SLNB procedures. Future clinical studies are needed to confirm our novel findings.

Materials Sciences and Applications (MSA) , 2013, DOI: 10.4236/msa.2013.48055
Abstract:

A carbonization method is reported to improve the thermal conductivity of carbon nanotube (CNT) arrays. After being impregnated with phenolic resins, CNT arrays were carbonized at a temperature up to 1400°C. As a result, pyrolytic carbon was formed and connected non-neighboring CNTs. The pyrolysis improved the room temperature conductivity from below 2 W/m·K up to 11.8 and 14.6 W/m·K with carbonization at 800°C and 1400°C, respectively. Besides the light mass density of 1.1 g/cm3, the C/C composites demonstrated high thermal stability and a higher conductivity up to 21.4 W/m·K when working at 500°C.
