News sentiment has been empirically observed to have impact on financial market returns. In this study, we investigate firm-specific news from the Thomson Reuters News Analytics data from 2003 to 2014 and propose an optimal trading strategy based on a sentiment shock score and a sentiment trend...

News sentiment has been empirically observed to have impact on financial market. However, finding a clear predictor of market returns using news sentiment remains a challenging task. This study investigates the relationship between news sentiment and cumulative market returns and volatility. We...

Ni60 + TiC + x Y 2 O 3 (x = 0,1,3) alloy coatings were prepared by laser cladding. The addition of rare earth oxides significantly changed the size and morphology of TiC in the coating, and the morphology of TiC changed from bulk to fine dendrite. In addition, with the addition of rare earth...

For uncertain strict-feedback nonlinear systems (SFNSs), the adaptive back stepping control is a popular method, yet this method requires repeatedly differentiating virtual control inputs, which will result in the "explosion of complexity" problem. In this article, an alternative control method...

In this paper, a novel conditional focus probability learning model, termed MCNN, is proposed for multi-focus image fusion (MFIF). Given a pair of source images, their conditional focus probabilities can be generated by using our MCNN trained well, which is further converted into the binary...

We use a social network analysis to examine the role of various types of interactions among the faculty of an American engineering school, ranging from mere awareness to full coauthorship, on academic research productivity (measured by weighted publication rates) and impact (measured by weighted...
