Using a square-gradient density functional model we test the prediction that the filling transition for a fluid in a wedge geometry changes from continuous to first-order as the wedge becomes more acute. Our numerical findings confirm such a change of order, but the value of the tilt angle at which it occurs, α* ≈ 45°, is considerably smaller than the original theoretical prediction. We critically reassess this work, which was based on allowing for the self-interaction of the fluid interface, and argue that the interfacial curvature and effective wavevector dependent surface tension can further lower the predicted value of α*, in keeping with our numerical findings. Interfacial fluctuation effects, occurring beyond mean-field level, are also discussed using effective Hamiltonian theory and are shown to substantially increase the value of α*. 相似文献

Since the establishment of the Shanghai Stock Exchange (SHSE) in 1990 and the Shenzhen Stock Exchange (SZSE) in 1991, China’s
stock markets have expanded rapidly. Although this rapid growth has attracted considerable academic interest, few studies
have examined the ability of conventional financial models to predict the share price movements of Chinese stock. This gap
in the literature is significant, given the volatility of the Chinese stock markets and the added risk that arises from the
Chinese legal and regulatory environment. In this paper we address this research gap by examining the predictive ability of
several well-established forecasting models, including dynamic versions of a single-factor CAPM-based model and Fama and French’s
three-factor model. In addition, we compare the forecasting ability of each of these models with that of an artificial neural
network (ANN) model that contains the same predictor variables but relaxes the assumption of model linearity. Surprisingly,
we find no statistical differences in the forecasting accuracy of the CAPM and three-factor model, a result that may reflect
the emerging nature of the Chinese stock markets. We also find that each ANN model outperforms the corresponding linear model,
indicating that neural networks may be a useful tool for stock price prediction in emerging markets. 相似文献
