A time-domain technique applicable to numerical and experimental application is used to determine the radiation Q of a turnstile antenna as a function of relatï e phasing between the two dipoles. Results confirm the theory that Q is a minimum with the dipoles in phase quadrature. Q 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 95]100, 2000.

OEDIPUS is a Monte Carlo simulation program which can be used to determine the small-x evolution of a heavy onium using Mueller's colour dipole formulation, giving the full distribution of dipoles in rapidity and impact parameter. Routines are also provided which calculate onium-onium scattering amplitudes between individual pairs of onium configurations, making it possible to establish the con...

We introduce a new particle shape which shows preferential rotation in three dimensional homogeneous isotropic turbulence. We call these particles chiral dipoles because they consist of a rod with two helices of opposite handedness, one at each end. 3D printing is used to fabricate these particles with a length in the inertial range and their rotations are tracked in a turbulent flow between os...

The time-average power radiated by a pair of infinitesimal dipoles is examined as their spacing is varied. The results elucidate the effect of the interaction of the dipoles on their radiation. (Some figures in this article are in colour only in the electronic version)

The residual resistivity ρ in metals caused by wedge disclination dipoles is studied in the framework of the Drude formula. It is shown that ρ ∼ L −p with p = 3 for biaxial and p = 2 for uniaxial dipoles (L is a size of dipole arm).

Objective Spike foci in benign epilepsy with centrotemporal spikes (BECTS) are related to seizure semiologies, but this relationship is inconspicuous in Panayiotopoulos syndrome (PS). We analyzed spike-associated high-frequency activity (HFA) and its relationship to spike foci in the electroencephalograms (EEGs) of patients with BECTS and PS in order to elucidate the pathophysiology of these ep...

The small-xB deep inelastic scattering in the saturation region is governed by the non-linear evolution of Wilson-line operators. In the leading logarithmic approximation it is given by the BK equation for the evolution of color dipoles. I discuss recent calculation of the next-to-leading order evolution of color dipoles in QCD and N = 4 SYM.
