Phase equilibrium lines (denoted ph-eq lines) of face-centered-cubic (fcc) and body-centered-cubic (bcc) phases, as well as saddle-point equilibrium lines (denoted sp-eq lines) in Al and Ca are studied by first-principles total-energy calculations. For a non-vibrating crystal of Al we ...
The band structure calculation results in 1.04 eV for the direct band gap. Two kinds of 蟽 and 蟺 bonds were determined in the band structure. Our results are in good agreement with experiment and pseudopotential calculations.S Javanbakht
Recent progress in the use of molecular dynamics (MD) to investigate the primary state of damage due to displacement cascades in metals is reviewed, with particular emphasis on the influence of crystal structure. Topics considered include the effect on defect formation in pure metals and alloys of...

The U.S. telecommunications regulator has raised mounting concerns about Chinese telecom companies in recent years which had won permission to operate in the United States decades ago. In 2019, the FCC voted to deny state-owned Chinese telecom firm China Mobile Ltd the r...
