Random fibre lasers are a special class of lasers in which the feedback arises from multiple …

Analysis of decision-making options in complex technical system design

V Nemtinov, A Zazulya, V Kapustin… - Journal of physics …, 2019 - iopscience.iop.org
In this article, we present a scheme of sequential analysis and elimination of variants that
does not use the idea of step-by-step decision making and can be implemented for analysis …

Anomalous wave statistics induced by abrupt depth change

CT Bolles, K Speer, MNJ Moore - Physical review fluids, 2019 - APS
Laboratory experiments reveal that variations in bottom topography can qualitatively alter
the distribution of randomized surface waves. A normally distributed, unidirectional wave …

Turbulence hierarchy and multifractality in the integer quantum hall transition

ALR Barbosa, THV de Lima, IRR González… - Physical Review Letters, 2022 - APS
We offer a new perspective on the problem of characterizing mesoscopic fluctuations in the
interplateau regions of the integer quantum Hall transition. We found that longitudinal and …
