Key messageThe alternative pathway activity involves in the species-specific responses to rust infection in two desert sister poplars, which may associate withAOXgenes expression regulation and adaptive evolution. Abstract Rust fungi are globally important poplar tree pathogens. However, little is known about species-specific responses to rust infection in poplars and the associated changes in alternative...
The electromagnetic scattering from the rough surface of three-layered medium is studied, the formulae of the scattering coefficient for different polarization is derived using the small perturbation method. An exponential distributed rough surface is presented for describing the natural rough soil surface of layered medium, the influence of the permittivity of substrate medium, the permittivity and...
A composite random rough surface model is presented for describing rough sea surface covered with oil films, the electromagnetic scattering from this sea surface is studied based on the Stratton-Chu integral equations. A general expression for the radar cross section is derived taking into account a modulation of the rough surface by long surface waves, and the formulae of bistatic scattering coefficient...
Field emission cathode of Ti-based nano-diamond coating is prepared by electrophoresis. The test of field emission characteristics shows it can achieved stable field emission. Threshold field strength of samples is 5.8V/μm, and field emission current density can achieve 70.2μA/cm² under 20V/μm field strength. the prepared field emission cathode is applied to the FED, and then the logic circuits at...
