Modes, the characteristic symmetric focal patterns of an ultrasound phased array, prove especially useful for hyperthermia. Modes cancel the complex pressure fields exactly along the central axis, eliminating axial constructive interference both proximal and distal to the treatment volume. A simple calculation exploits planar or rotational array symmetry(More)
Aiming at tackling the difficulty in exactly constituting the sea surface temperature (SST) dynamical model, the paper introduces the dynamical system reconstruction idea and establishes the nonlinear dynamical model of SST field based on 1963-2010 monthly average Hadley SST data. Time coefficients series after empirical orthogonal functions decomposition(More)
