Estimation of the Degree of Polarization for Hybrid/Compact and Linear Dual-Pol SAR Intensity Images: Principles and Applications [PDF]

, 2013
Analysis and comparison of linear and hybrid/compact dual-polarization (dual-pol) synthetic aperture radar (SAR) imagery have gained a wholly new importance in the last few years, in particular, with the advent of new spaceborne SARs such as the Japanese

Coulomb gluons will generally destroy coherence

Journal of High Energy Physics, 2021
Coherence violation is an interesting and counter-intuitive phenomenon in QCD. We discuss the circumstances under which violation occurs in observables sensitive to soft radiation and arrive at the conclusion that almost all such observables at hadron ...

Coherence of European Union Actions at the UN Human Rights Council and the Council of Europe

Vestnik MGIMO-Universiteta, 2019
The current methodological debates on the EU external actions at international organisations raise the issue of the EU coherence. The scholarship tends to focus on EU vertical and horizontal coherence in various policies, making the EU internal ...

Robust measurement of orbital angular momentum of a partially coherent vortex beam under amplitude and phase perturbations

Opto-Electronic Science
The ability to overcome the negative effects, induced by obstacles and turbulent atmosphere, is a core challenge of long-distance information transmission, and it is of great significance in free-space optical communication.

Variant-Coherence Gaussian Sources

Photonics, 2021
The celebrated Gaussian Schell model source with its shift-invariant degree of coherence may be the basis for devising sources with space-variant properties in the spirit of structured coherence.

Non-stationary pulses with complex-valued temporal degree of coherence

, 2020
It is shown that fine phase structuring of the temporal degree of coherence of a non-stationary pulse source leads to breaking its average arrival time symmetry on propagation in a linear dispersive medium.

Determinants of sense of coherence among managerial nursing Staff [PDF]

, 2015
[b]Introduction.[/b] The sense of coherence is a tool for confronting the challenges posed by life. It constitutes a general human orientation, which is expressed through the conviction that outside stimuli can be explained; there are resources allowing ...

Statistical properties of spontaneous synchrotron radiation with arbitrary degree of coherence

Physical Review Accelerators and Beams, 2020
In a storage ring, turn-to-turn fluctuations in the intensity of spontaneous synchrotron radiation occur due to two mechanisms. The first mechanism is the quantum uncertainty in the number of emitted photons.

Second-Order Statistics of Partially Coherent Beams with Laguerre Non-Uniform Coherence Properties under Turbulence

Photonics, 2023
We use the extended Huygens–Fresnel integral to analyze the propagation properties of a class of partially coherent beams with Laguerre non-uniform coherence properties (called Laguerre non-uniformly correlated beams) in free space and in a turbulent ...

Self-Focusing Property of Partially Coherent Beam With Non-Uniform Correlation Structure in Non-Linear Media

Frontiers in Physics, 2022
Coherence in a light beam has the potential to serve as a degree of freedom for manipulating the beam. In this work, the self-focusing property of a partially coherent beam with a non-uniform correlation structure propagating in a non-linear medium is ...
