Multi-photon ionization (MPI) in plasma is examined in terms of optical metric, and the quantum Volkov state in curvedspace-time is derived. The cross section o
Daily return series of Dow Jones Industrial Average Index (DJIA) and Shanghai Conposite Index are investigated using spec-tral analysis methods. The day-of-the-
An analytical method for predicting chaos in perturbed planar non-Hamiltonian integrable systems with slowly varying pa-rameters was developed. Based on the ana
This paper introduces architectures of two types optical packet-switched metropolitan area networks and their media accesscontrol protocols. We have designed re
