To determine the electron energy spectra for medical accelerator effectively, we investigate a nonlinear programming model with several nonlinear regression alg
Syringe-shaped GaN nanorods are synthesized on Si(111) substrates by annealing sputtered Ga2O3/BN films under flowing ammonia at temperature of 950° C. Most of
Temperature-dependent characteristics of SiGeC p-i-n diodes are analysed and discussed. Based on the ISE data, the temperature-dependent physical models applica
A systematics of excitation energy of the first 2+ state E2+1 in even-even heavy nuclei (A ≥ 120) is studied in the NpNn scheme. It is found that a simple expo
