we can see that the stock price rose from nearly $70 in 2016 to as high as $117 in 2018 before retracing back to ~$97.50 by year-end. Also, dividends rose from 28 cents in 2016 to 48 cents in 2018. Proponents of dividend signaling could point to Lowes as an example of executive ...
In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review. You ask a question, read up on what has been studied before, and then form a hypothesis. A hypothesis is usually tentative; it's an assumption or sugge...

Despite recent advances of data acquisition and algorithms development, machine learning (ML) faces tremendous challenges to being adopted in practical catalyst design, largely due to its limited generalizability and poor explainability. Herein, we develop a theory-infused neural network (TinNet) approach...
