Using modified analytic embedded atom method and molecular dynamics (MDs) simulation, the self-diffusion dynamics behaviors of Pd adatom on perfect Pd(110) and reconstruction Pd(110)-(1 × 2) surfaces have been studied. Our simulations show the diffusion of Pd adatom is 1D motion along the...

We consider a two-component diffusion process with the second component treated as the observations of the first one. The observations are available only until the first exit time of the first component from a fixed domain. We derive filtering equations for an unnormalized conditional...

Using a sample of 2198 completed M&A transactions between 1994 and 2010 in which both target and acquirer are public US firms supplemented with hand-collected data for target CEO retention, we uncover a significantly negative relation between target CEO retention and takeover premiums received...

Using options-implied variance, a forward-looking measure of conditional variance, we revisit the debate on the idiosyncratic risk-return relation. In both cross-sectional (for individual stocks) and time-series (for the market index) regressions, we find a negative relation between...
