Inhibiting the diffusion and aggregation of hydrogen atoms can effectively improve the hydrogen-induced delayed fracture resistance of high strength hot-stamped steel. Here we investigate the interaction between dislocations, precipitates and hydrogen atoms in a 2000 MPa grade hot-stamped steel...

When rolling aluminum (Al)/magnesium (Mg)/aluminum (Al) composite plates with large reduction, there are often differences in matrix structure and hard brittle properties of interfacial intermetallic compounds, which have a negative impact on the mechanical properties. Therefore, it is necessary...

We estimate a large data panel of carbon emissions by US firms with a machine learning algorithm known as XGBoost. We estimate scope 1 carbon emissions of listed firms from 2002 to 2021. This data set has broad coverage of 4111 firms per year as compared to 1675 firms provided by data vendors....

The quality of financial reporting shows how informative the accounting numbers are for decision-making. Because business outlook can influence financial reporting quality, this study examined predictable, moderately predictable and unpredictable business outlooks. The study randomly selected...
