Polarization-encoded imaging consists of the distributed measurements of polarization parameters for each pixel of an image. We address clustering of multidimensional polarization-encoded images. The spatial coherence of polarization information is considered. Two methods of analysis are proposed: polarization contrast enhancement and a more-sophisticated image-processing algorithm based on a M...

Cell polarization is a process of coordinated cellular rearrangements that prepare the cell for migration. GM1 is synthesized in the Golgi apparatus and localized in membrane microdomains that appear at the leading edge of polarized cells, but the mechanism by which GM1 accumulates asymmetrically is unknown. The Golgi apparatus itself becomes oriented toward the leading edge during cell polariz...

We calculate exact analytical expressions for O(αs) 3-jet and O(α2 s) 4-jet cross sections in polarized deep inelastic lepton nucleon scattering. Introducing an invariant jet definition scheme, we present differential distributions of 3and 4-jet cross sections in the basic kinematical variables x and W 2 as well as total jet cross sections and show their dependence on the chosen spin-dependent ...

A previous analysis of the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI ) observation of GRB 021206 found that the gamma-ray flux was 80±20% polarized. We re-examine this data and find no signal that can be interpreted as due to polarization. First, we find that the number of scattering events suitable for measuring polarization – having been scattered from one detector to anoth...

The cross-section for WW → WW with arbitrarily polarized W bosons is calculated within the Electroweak Standard Model including the complete virtual and softphotonicO(α) corrections. We show the numerical importance of the radiative corrections for the dominating polarized cross-sections and for the unpolarized cross-section. The numerical accuracy of the equivalence theorem is investigated in ...

We review the achievements of the theory of polarization bremsstrahlung of relativistic particles, including the case when both colliders have internal structure. The main features which the relativistic effects bring into the problem are discussed and illustrated by the results of numerical calculations.

the density and polarization profiles of the dipolar hard ellipsoids confined between hard walls are studied using the density functional theory (dft). the hyper-netted chain (hnc) approximation is used to write excess grand potential of the system with respect to the bulk value. the number density is expanded up to zero and first order in polarization to find the results. for the zero order in...

We review the developments made during the last decade in the theory of polarization bremsstrahlung in the non-relativistic domain. A literature survey covering the latest history of the phenomenon is given. The main features which distinguish the polarization bremsstrahlung from other mechanisms of radiation are discussed and illustrated by the results of numerical calculations.

A previous analysis of the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI ) observation of GRB 021206 found that the gamma-ray flux was 80±20% polarized. We have re-examined this data, and we detect no signal which can be interpreted as due to polarization for GRB 021206. First, we find the number of scattering events capable of measuring polarization, due to a photon scattered fr...

In this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled InAs/GaAs quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. The microcavity wafer sample is grown by molecular beam epitaxy (MBE) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...
