The electronic stopping power of palladium (Pd) for protons is investigated based on time-dependent density functional theory combined with Ehrenfest molecular dynamics simulations. Pd explicitly considering inner electrons calculated and the excitation mechanism revealed. velocity proportionality low-energy reproduced. Our study verified that electron contributes significantly to in high energy range, which strongly dependent impact parameter. obtained from off-channeling geometry...
The electronic stopping power of protons and He ions traveling along the channeling off-channeling trajectories in indium is reported based on time-dependent density functional theory combined with Ehrenfest molecular dynamics simulations. We provided an intuitive description for a wide range ion energies, revealed microcosmic excitation mechanism semicore $4d$ electrons In. velocity-proportional kink velocity which due to $4d$-electron are reproduced low-energy regime. Because $5s5p$...
The electronic stopping power of protons traveling along the channeling and off-channeling trajectories in platinum (Pt) is reported based on time-dependent density functional theory calculations for electrons combined with Ehrenfest molecular dynamics simulations ions real time space. We provided an intuitive description a wide range ion energies, revealed excitation mechanism inner $4f$ Pt. comparison calculation results experimental data showed that conduction are sufficient to describe...
The electronic stopping power of magnesium for protons and He ions is studied by a nonequilibrium approach based on real-time time-dependent density-functional theory combined with Ehrenfest molecular-dynamics simulation. Mg energetic calculated, the microscopic excitation mechanism inner $2p$ electron its contribution to revealed. In low-energy range, velocity proportionality displayed. displays deviations from proportionality, which ascribed structure that enables an additional energy-loss...
The electronic stopping power of zinc oxide for protons is presented over a wide range velocities by using real-time time-dependent density functional theory. We calculated the energetic both channeling and off-channeling trajectories, revealed microcosmic mechanism semicore $3d$-electron excitation in ZnO. In low-energy regime, obtained from geometry quantitative agreement with measured data, which reproduced not only experimental threshold velocity power, but also deviation...
With the development of Distribution Internet Things, number data acquisition equipment in low-voltage station area has exploded, making it difficult to configure processing each information node. Identifying key nodes communication network platform is beneficial enhance reliability and make resource allocation reasonable efficient. Therefore, this paper proposes a node identification technology suitable for topology. Firstly, based on power service flow network, Theil entropy change...
