The high-frequency properties of a two-dimensional electron gas (2DEG) are determined by the dynamic conductivity, σ(ω, q), where ω and q are the angular frequency and the wavevector

Figure 7a shows the differences between the actual landing point of each recovered radiosonde and the ones simulated using hor- izontal wind profiles forecasted by Arome at the time

Although full DG or Spectral-Element methods have been developed respectively for high order Boussinesq equations in [ 31 ] and fully nonlinear water waves in [ 32 ], there is still

This section is devoted to the derivation of a new Green-Naghdi asymptotic model for the water-waves equations in the shallow water (µ ≪ 1) of the same accuracy as the standard

The results show that the same traps cause dispersion in output conductance and give rise to low frequency noise in these devices. Our results indicate that the high electric
