Abstract In 2021 JET exploited its unique capabilities to operate with T and D–T fuel an ITER-like Be/W wall (JET-ILW). This second major campaign (DTE2), after DTE1 in 1997, represented the culmination of a series enhancements—new fusion diagnostics, new injection capabilities, refurbishment plant, increased auxiliary heating, in-vessel calibration 14 MeV neutron yield monitors—as well as significant advances plasma theory modelling community. DTE2 was complemented by sequence isotope...
We introduce a Mueller-matrix imaging polarization-based approach for the quantitative digital screening of polycrystalline structure fibrillary-based biological tissues in vitro. The morphometric evaluation histological sections myocardium was performed utilizing high-order statistical moments calculated based on spatial distribution linear and circular birefringence dichroism obtained experimentally. demonstrate that distributions phase light optical anisotropy scattering inherent to...
We present in this work the results of an investigation to analyse coordinate distributions azimuths and ellipticity polarization (polarization maps) laser images blood plasma layers for three groups patients: healthy (group 1), mastopathy 2) breast cancer 3). To characterize maps all samples we use parameters: statistical moments first fourth orders, autocorrelation functions logarithmic dependences power spectra related inherent plasma. ascertain criteria diagnosis differentiation...

The relationship established between mechanisms optical histological sections rectal tissue biopsy different spectral regions. ranges changes statistical moments 1st-to-4th orders, which distribution azimuth-invariant elements...
Abstract Imaging diagnostics in Joint European Torus have become essential the study of plasma wall interactions and protection facing components. During deuterium operations, location these was at close proximity to vessel. However, for 50–50 deuterium-tritium operation, neutron yield impact onto electronics imaging would caused them fail completely locations. Shielding systems from neutrons is achieved by relocating a selected number outside Hall (i.e. other side biological shield wall)....
The present work is devoted to investigation of mechanisms optical anisotropy biological tissues polycrystalline networks and laser polarization fluorescence. model complex anisotropy, which takes into account both linear circular birefringence, as well dichroism fibrillar histological sections women reproductive sphere proposed. data statistical, correlation fractal processing coordinate distributions fluorescence provided. technique azimuthally invariant Mueller-matrix mapping protein in...
