Statistical properties of the radiation from SASE FEL operating in a post-saturation regime with and without undulator tapering

open access: yes, 2015
We describe statistical and coherence properties of the radiation from x-ray free electron lasers (XFEL) operating in the post-saturation regime. We consider practical case of the SASE3 FEL at the European XFEL.

Potential Landslide Identification in Baihetan Reservoir Area Based on C-/L-Band Synthetic Aperture Radar Data and Applicability Analysis

open access: yesRemote Sensing
The Baihetan reservoir region is characterized by complex geomorphology, significant altitude differences, and rugged terrain. Geological hazards in such areas are often characterized by high concealment, wide distribution, and difficulty in field ...

The fundamental problem of treating light incoherence in photovoltaics and its practical consequences

open access: yesNew Journal of Physics, 2014
The incoherence of sunlight has long been suspected to have an impact on solar cell energy conversion efficiency, although the extent of this is unclear.

The Life Mission Theory VII. Theory of Existential (Antonovsky) Coherence: A Theory of Quality of Life, Health, and Ability for Use in Holistic Medicine

open access: yesThe Scientific World Journal, 2005
A theoretical framework of existential coherence is presented, explaining how health, quality of life (QOL), and the ability to function were originally created and developed to rehabilitate human life from an existential perspective.

On the inverse problem of source reconstruction from coherence measurements

open access: yes, 2018
We consider an inverse source problem for partially coherent light propagating in the Fresnel regime. The data is the coherence of the field measured away from the source.

Statistical structure of the biological tissue scattering of laser field with the complex degree of coherence [PDF]

open access: yesSemiconductor Physics Quantum Electronics and Optoelectronics, 2014
Diagnostic efficiency of differentiation of birefringence of rat's biological tissues in different physiological states is studied in this research based on application of the correlation approach. Interrelation between coordinate distributions of complex degree of coherence (CDC) and changes in birefringence has been determined.

Adaptive Flexibility of the City’s Complex Systems

open access: yesBuildings
The city represents a complex adaptive system consisting of a set of interconnected subsystems within self-organization and flexible structures that give it the ability to adapt to continue operating over time.

The dependence of exciton transport efficiency on spatial patterns of correlation within the spectral bath

open access: yesNew Journal of Physics, 2013
Spatial correlations in spectral bath motions have been proposed to explain long-lived coherence in exciton transport. Systems of interest, ranging from photosynthetic complexes to organic photovoltaics, contain inhomogeneous environments.

ELEMENTS D’ORGANISATION DE L’ESPACE DU SUD DE LA BUCOVINE [PDF]

open access: yesRevue Roumaine de Géographie, 2014
Elements of space organisation in south Bucovina. Featuring original identity and a degree of coherence, the Bucovinean cultural space is tantamount to a kind of community spiritual fulfillment, unfortunately severed at regional level. We have deemed it

Generalized spectroscopy; coherence, superposition, and loss [PDF]

open access: yes, 2007
We analyze single particle coherence and interference in the presence of particle loss and derive an inequality that relates the preservation of coherence, the creation of superposition with the vacuum, and the degree of particle loss.
