Estimates of Stellar Weak Interaction Rates for Nuclei in the Mass Range A=65-80 [PDF]
, 2002 We estimate lepton capture and emission rates, as well as neutrino energy loss rates, for nuclei in the mass range A=65-80. These rates are calculated on a temperature/density grid appropriate for a wide range of astrophysical applications including ...

Power-Synchronized Grid-Following Inverter Without a Phase-Locked Loop
IEEE Access, 2021 This paper proposes a power-synchronized control strategy for grid-following inverters (GFLIs) to regulate their power exchange with the grid without any need for sensing/regulating the point of connection voltage.

Velocity-gauge real-time TDDFT within a numerical atomic orbital basis set [PDF]
, 2017 The interaction of laser fields with solid-state systems can be modeled efficiently within the velocity-gauge formalism of real-time time dependent density functional theory (RT-TDDFT). In this article, we discuss the implementation of the velocity-gauge
