The eddy-driven jet is located in the midlatitudes, bounded on one side by the pole and often bounded on the opposite side by a strong Hadley-driven jet. This work explores how the eddy-driven jet and its variability persist within these limits. It is demonstrated in a barotropic model that as the jet is located at higher latitudes, the eddy length scale increases as predicted by spherical Ross...

We investigate the determination of the σ pole from ππ scattering data below the KK̄ threshold, including the new precise results obtained from Ke4 decay by NA48/2 Collaboration. We discuss also the experimental status of the threshold parameters a00 and b 0 0 and the phase shift δ 0 0 . In order to reduce the theoretical bias, we use a large class of analytic parametrizations of the isoscalar S...

The aim of this contribution is to analyze a class of state-space subspace system identiication (4SID) methods. In particular, the eeect of diierent weighting matrices is studied. By a linear regression formulation, diierent cost-functions, which are rather implicit in the ordinary framework of 4SID, are compared. Expressions for asymptotic variances of pole estimation error are analyzed and fr...

Several previous studies in adults have investigated how one- and two-dimensional moving features are integrated into a coherent global motion percept by studying the "barber-pole illusion"; when a one-dimensional moving grating is presented within a rectangular aperture, the two-dimensional line terminators at the edges of the aperture bias the perceived direction of motion toward the longer a...

The pole structure of the low energy ππ scattering amplitudes is studied using a proper chiral unitarization method combined with crossing symmetry and the low energy phase shift data. It is found that the σ pole position is at M σ = 470 ± 50M eV , Γ σ = 570 ± 50M eV. The existence of the virtual state pole in the IJ=20 channel is reconfirmed. Various threshold parameters are estimated and are ...
