We have collected 18 γ-ray-loud BL Lac with observed data in multiwavedand, we find that γ-ray flux densities correlate better with the near-IR flux densities
The flux density structure functions of PSRs B0525+21 and B2111+46 are calculated with the refractive interstellar scintillation (RISS) theory. The theoretical
We first give the theoretical result of the stabilization of general discrete chaotic systems by using impulsive control. As an example and an application of th
With the help of a weak linearly polarized low-frequency field, we study high-order harmonic generation in a circularly polarized high-frequency field. Although
Differential cross sections for the elastic scattering of electrons by H2 at 100 eV and 150 eV have been calculated and compared with experiments. We use the mo
We study the escape problem of a bistable sawtooth system driven by correlated multiplicative and additive white noises. Exact analytic representation of the re
