In this paper, a Multiphysics coupling simulation model of flow and acoustics is proposed using COMSOL software, and its results are verified by comparing with experimental results of others.Then, the aerodynamic pressure above the bluff body surface at a speed of 350 km/h is simulated.Moreover, a near-zero-impedance acoustic metasurface composed o

A revision of the New Zealand endemic Lepidium oleraceum and allied species is presented.Sixteen species are recognised, 10 of these are new.The new species are segregated on the basis of morphological characters supported by molecular data obtained from three DNA markers (two rDNA and one cpDNA).One species, L.castellanum sp.nov., is endemic to th
