TL;DR: New endoscopic OCT technology is evaluated and the feasibility of carrying out UHR OCT imaging in conjunction with standard endoscopy for in vivo real-time imaging of Barrett's esophagus, dysplasia, and esophageal adenocarcinoma is demonstrated.

TL;DR: The radial dependence of the statistical properties of plasma fluctuations and induced fluxes have been investigated in the plasma boundary region of the TJ•I tokamak [I. Garcia-Cortes et al., Phys. B 4, 4007 (1992)] and the TJ‐IU torsatron [E. Ascasibar et al. as discussed by the authors ].

TL;DR: In this paper, the authors analyzed the edge plasma fluctuation in several confinement devices and revealed the self-similar character of the fluctuations through the presence of long-range time correlations, and showed that the tail of the autocorrelation function decays as a power law for time lags longer than the decorrelation time and as long as times on the order of the particle diffusion time.

TL;DR: In this paper, the rescaled range analysis was used to investigate long-range dependence in plasma edge fluctuations, which revealed the self-similar character of the electrostatic fluctuations at the plasma edge with selfsimilarity parameters ranging from 0.62 to 0.72.

TL;DR: In this paper, it was shown that the electrostatic potential and density fluctuations at the plasma edge are self-similar over a broad range of time scales, in general for time scales longer than the turbulence decorrelation times up to times of the order of confinement time, the mesoscale range.
