Diffractive shaping of excimer-laser beams for pulsed laser deposition [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2011
We present a beam-shaping system for a pulsed laser deposition setup. This system is based on two diffractive beam-splitter gratings and is able to produce 2 × 2 mm2 flat-top distributions of UV light with a fluence of 3 J/cm2 on the target some 30 cm ...

Eigenvalue calibration methods for polarimetry [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2012
Complex polarisation sensitive systems such as imaging Mueller matrix polarimeters are commonly calibrated using the eigenvalue calibration method. In this paper we present an extensive review of the method and an existing variant.

Multiscale coherence analysis of reference evapotranspiration of north-western Iran using wavelet transform

open access: yesJournal of Water and Climate Change, 2022
This study applies different wavelet coherence formulations for investigating the multiscale associations of reference Evapotranspiration (ET0) of Tabriz and Urmia stations in North West Iran with five climatic variables: mean temperature (T), pressure ...

Mathematical model and dynamical analysis of the human equilibrium seeking training [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2021
The purpose of this work is to determine the ability of the partial directed coherence method to identify the directed interaction between nonlinear systems correctly in presence of nonlinear couplings between systems, as well as in the case when the ...

A coherence theorem for pseudonatural transformations [PDF]

open access: yes, 2016
We prove coherence theorems for bicategories, pseudofunctors and pseudonatural transformations. These theorems boil down to proving the coherence of some free $(4,2)$-categories.

Partially coherent sources with radial coherence

open access: yesOptics Letters, 2018
Partially coherent sources with radial coherence are proposed. They present a circularly symmetric intensity profile and a degree of coherence whose absolute value only depends on the angular difference between the two considered points. In particular, the source is completely coherent at pairs of points belonging to the same radius.

Besinc Pseudo-Schell Model Sources with Circular Coherence

open access: yesApplied Sciences, 2019
Partially coherent sources with non-conventional coherence properties present unusual behaviors during propagation, which have potential application in fields like optical trapping and microscopy.

Consensus-Related Performance of Triplex MASs Based on Partial Complete Graph Structure

open access: yesEntropy, 2022
This article mainly studies first-order coherence related to the robustness of the triplex MASs consensus models with partial complete graph structures; the performance index is studied through algebraic graph theory.

Partially Coherent Direct Sum Channels [PDF]

open access: yesQuantum, 2021
We introduce Partially Coherent Direct Sum (PCDS) quantum channels, as a generalization of the already known Direct Sum quantum channels. We derive necessary and sufficient conditions to identify the subset of those maps which are degradable, and provide a simplified expression for their quantum capacities.
