Quantifying uncertainty in computer model predictions

DOE's National Energy Technology Laboratory (NETL) has great interest in technologies that will lead to reducing the CO2 emissions of fossil-fuel-burning power plants. Advanced energy technologies such as Integrated Gasification ...

Planet formation may start earlier than previously thought

On their long journey to form planets, dust grains may coalesce with each other much earlier than previously thought, simulations by RIKEN astrophysicists suggest1. This may mean revisiting conventional theories of planet ...

Remaining switched on to silicon-based electronics

The difficulty of further increasing the power conversion efficiency of silicon-based components in power electronics seems to indicate that we are reaching the limits of potential advances to this technology. However, a ...

Seeking out silent threats to simulation integrity

Large-scale computing has become a necessity for solving the nation's most intractable problems. Due to their sheer number of cores, high-end computers increasingly exhibit intermittently incorrect behaviors—referred to ...
