Experimental demonstration of singular-optical colouring of regularly scattered white light [PDF]
Journal of the European Optical Society-Rapid Publications, 2008 Experimental interference modelling of the effects of colouring of a beam traversing a light-scattering medium is presented. It is shown that the result of colouring of the beam at the output of the medium depends on the magnitudes of the phase delays of

Correlation Optics, Coherence and Optical Singularities: Basic Concepts and Practical Applications
Frontiers in Physics, 2022 The main idea of this review is to trace the interrelations and inter-transitions between the basic concepts and approaches of the correlation optics (including the light coherence) and the singular optics dealing with networks of “exceptional” points of

CLASSIFYING OPTICAL PROPERTIES OF SURFACE- AND BULK-SCATTERING BIOLOGICAL LAYERS WITH POLARIZATION SINGULAR STATES [PDF]
Journal of Innovative Optical Health Sciences, 2013 The results of singular approach usage in the tasks of description and classification of appearance of optical anisotropy of different types of phase-inhomogeneous biological layers (surface-scattering, optically thin and optically thick) have been ...

Harm reduction in Europe: a framework for civil society-led monitoring
Harm Reduction Journal, 2021 Background Civil society organisations (CSOs) play a vital role in developing and implementing effective measures to reduce the harms of drug use. They are also fundamental actors to monitor and evaluate programmes and policies for improvement.

Kibble–Zurek scaling due to environment temperature quench in the transverse field Ising model
Scientific Reports, 2023 The Kibble–Zurek mechanism describes defect production due to non-adiabatic passage through a critical point. Here we study its variant from ramping the environment temperature to a critical point. We find that the defect density scales as $$\tau ^{-d\nu

SSRN Electronic Journal, 2009 Correlations of equity returns have varied substantially over time and remain a source of continuing policy debate. This paper studies stock market correlations in an equilibrium model with heterogeneous risk aversion. In the model, preference heterogeneity causes variations in the volatility of aggregate risk aversion from good to bad states.

Correlated Initialization for Correlated Data [PDF]
Neural Processing Letters, 2022 Spatial data exhibits the property that nearby points are correlated. This also holds for learnt representations across layers, but not for commonly used weight initialization methods. Our theoretical analysis quantifies the learning behavior of weights of a single spatial filter.

Different phases of ATS use call for different interventions: a large qualitative study in Europe
Harm Reduction Journal, 2022 Background Amphetamine-type stimulants (ATS) are globally widely used. Scientific literature generally defines four phases of substance use (initiation, continuation, increase and decrease); however, there is limited understanding of what influences ...
