In order to understand the effect of surface heat dissipation on thermocapillary convection of low Prandtl number in a shallow annular pool, a series of three-dimensional numerical simulations were carried out by using the finite volume method. Results indicate that with the increase of surface heat dissipation, the thermocapillary convection intensity increases at first, and then decreases slightly; furthermore, the center of the thermocapillary convective cell moves gradually to the hot outer wall. With the increase of Marangoni number, the stable axisymmetric flow bifurcates orderly to the three-dimensional steady flow and the three-dimensional oscillatory flow at a weak surface heat dissipation. However, it bifurcates directly to the three-dimensional oscillatory flow at a strong heat dissipation. After thermocapillary convection destabilizes, the hydrothermal waves appear at the weak surface heat dissipation, but the longitudinal rolls near the outer wall are dominant at the strong heat dissipation. The flow pattern transition is always accompanied by the variations of the temperature fluctuation amplitude, the oscillatory frequency and the wave number. © 2017 Elsevier Ltd

Symbolic expressions are essential resources for producing knowledge, yet they are a source of learning difficulties in chemistry education. This study aims to employ social semiotics to analyse the symbolic representation of chemistry from two complementary perspectives, referred to here as contextual (i.e., historical) and functional. First, the contextual account demonstrates that symbolism was introduced to represent compounds according to their elemental composition, to quantify chemistry, and to explain reactivity. Further to this, the functional analysis shows that symbolic expressions entail a range of unique grammatical resources to create specialised forms of knowledge, which cannot be made by natural language alone. It is found that historically the symbolic representation was not originally directly related to the submicroscopic domain, nor did it develop sufficient means to offer particulate explanations, although an indirect link could be set up between Berzelian formulae and the submicroscopic theoretical models. It is also found that understanding the quantitative aspects is a necessary but not sufficient condition for effective engagement with the symbolic representation of chemistry. Finally the present study discusses the pedagogic implications stemming from the social semiotic account of chemical symbolism. © 2016 The Royal Society of Chemistry.

Huang L., Liu X. and Xu L. Regional innovation and spillover effects of foreign direct investment in China: a threshold approach, Regional Studies. Using a data set on twenty-nine Chinese provinces for the period 1985-2008, this paper establishes a threshold model to analyse the relationship between spillover effects of foreign direct investment (FDI) and regional innovation in China. There is clear evidence of double-threshold effects of regional innovation on productivity spillovers from FDI. Specifically, only when the level of regional innovation reaches the minimum innovation threshold will FDI in the region begin to produce positive productivity spillovers. Furthermore, positive productivity spillovers from FDI will be substantial only when the level of regional innovation attains a higher threshold. The double threshold divides Chinese provinces into three super-regions in terms of innovation, with most provinces positioned within the middle-level innovation super-region. Policy implications are discussed. © 2012 Copyright Regional Studies Association.

For the fusion problem of the multifocus images of the same scene, a novel scheme is proposed based on lifting stationary wavelet transform (LSWT) and a new m-channel pulse coupled neural network (PCNN). By using LSWT, we can calculate a flexible multiscale and shift-invariant representation of registered images. In order to overcome the shortcoming of PCNN which is not convenient and economical for a real system, a new m-channel PCNN is proposed and used to fuse the subband coefficients of LSWT. For choosing the low frequency subband coefficients, we take energy of Laplacian of image, which can effectively represent the salient features and sharp boundaries of image in LSWT domain, as input to motivate the m-channel PCNN. When choosing the bandpass subband coefficients, the local neighborhood sum of Laplacian (LNSL) measurement is introduced and taken as external stimulus to motivate the m-channel PCNN. The algorithm has been used to merge several sets of multi-focus images; both visual and quantitative analysis show that, comparing with conventional image fusion algorithms, the proposed approach can provide a more satisfactory fusion outcome. © 2011 by Binary Information Press.

Analyzing carbon emissions is critical for successfully managing sustainable production and consumption. In a dual channel supply chain that includes traditional retailers and online e-tailers, consumer free riding often occurs when consumers enjoy the services provided by a traditional retailer but make purchases at a lower price from an e-tailer. The specific aim of this paper, therefore, is to evaluate the impact of consumer free riding on carbon emissions in a product's life cycle across a dual channel closed loop supply chain and to assess the effect of governmental e-commerce tax on carbon emissions. The study comprises a systematic comparison and numerical analysis of cases in which consumers do or do not free ride. Our results show that although manufacturers may gain economic benefits from consumer free riding behavior, total carbon emissions across the supply chain increase too, and a governmental tax on e-commerce can help reduce consumer free riding and total carbon emissions. Our research also suggests that, a government may have to subsidize the e-tailer in the consideration of maximizing the social welfare. © 2016 Elsevier Ltd.

The thesis examines the relationship between managerial ownership and firm performance for 66 samples of Chinese public State-owned enterprises (SOEs) privatized by doing Management Buyout (MBO) over the period from 1997 to 2009. The empirical results indicate that managerial ownership has a negative effect on firm performance. It also finds that firms with high managerial ownership exhibit a worse performance decline. The firms which are under High-low percentage managerial ownership provide a positive effect on OROA, NROA and Tobin's Q surprisingly. The relationship between managerial ownership and firm performance which occurs at High-low levels of managerial ownership experiences better performance compared to High and Low level. ©2011 IEEE.

We present the rationale and study design of the CGMT (combined gefitinib and metformin therapy) trial ( Identifier: NCT01864681), which is aimed at treating locally advanced non-small-cell lung cancer. The CGMT trial is a multicenter, phase II randomized, double-blinded, and placebo-controlled study, which is designed to evaluate the safety and efficacy of metformin in combination with gefitinib as first-line therapy in patients presenting with stage IIIb-IV non-small-cell lung cancer expressing the epidermal growth factor receptor mutant. Two therapies are proposed for this trial. The first regimen is comprised of gefitinib plus metformin. The second therapy is comprised of gefitinib plus placebo. The primary objective of this trail is to compare the progression-free survival rate at year 1 of the study. The secondary objective of this trial is to compare the 2-year overall survival, the 2-year progression-free survival, the objective response rate, and the disease-control rate, and to evaluate the relative safety of both therapies. Based on the statistical design, we plan to enroll approximately 200 patients.
