In this paper we propose recurrence relations for the dipole densities in QCD, which allows us to find these from solution BFKL equation. We resolve diffusion approximation kernel. Based on solution, found sum of large Pomeron loops. This generates scattering amplitude that decreases at values rapidity $Y$. It turns out such behaviour amplitudes is an artifact approximation. leads unitarization...
We propose a two-dimensional model for a multilayer stack of dipolar Bose-Einstein condensates formed by a strong optical lattice. We derive effective intraand interlayer dipole-dipole interaction potentials and provide simple analytical approximations for a given number of lattice sites at arbitrary polarization. We find that the interlayer dipole-dipole interaction changes the transverse aspe...
Three-dimensional geoelectrical surveys are widely used to map the subsurface in areas with complex geology. Field survey methods using offset pole–dipole and dipole–dipole arrays have been proposed large efficiently. However, it has found that negative apparent resistivity values sometimes encountered contrasts, particularly when offsets between current electrodes potential dipoles used. The v...
A finite image I is a function assigning colors to a finite, rectangular array of discrete pixels. Thus, the information directly encoded by I is purely locational. Such locational information is of little visual use in itself: perception of visual structure requires extraction of relational image information. A very elementary form of relational information about I is provided by its dipole hi...
A simplified scheme for the investigation of cooperative effects in the quantum jump statistics of small numbers of fluorescing atoms and ions in a trap is presented. It allows the analytic treatment of three dipole-dipole interacting four-level systems which model the relevant level scheme of Ba ions. For the latter, a huge rate of double and triple jumps was reported in a former experiment an...
The magnetic ordering due to the long range dipole coupling in an ensemble of magnetic islands is investigated. If the islands are large enough and closely separated, the average dipole energy per island can explain the magnitude of the observed ordering temperature of such an ensemble (U. Bovensiepen et al., J. Magn. Magn. Mater. 192, L386 (1999)). The energetical degeneracy with respect to a ...
phospholipids are important for the biological lipid and are commonly used in biophysical studies.A quantumcalculation for two phospholipids Dipalmitoylphosphatidylethanolamine and dipalmitoylphosphatidic acidwere performed using the abinitio software. Geometry optimization structures were obtained at RHF level using3-21G, 6-31G*. These basis sets were used To understanding the effects of envir...
