Evaluation of retinal nerve fiber layer thickness measurements using optical coherence tomography in patients with tobacco-alcohol-induced toxic optic neuropathy
(ALL INDIA OPHTHALMOLOGICAL SOC, 2010)
Three patients with progressive visual loss, chronic alcoholism and tabagism were submitted to a complete neuro-ophthalmic examination and to retinal nerve fiber layer (RNFL) measurements using optical coherence tomography ...
Robust tori-like Lagrangian coherent structures
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In general the term "Lagrangian coherent structure" (LCS) is used to make reference about structures whose properties are similar to a time-dependent analog of stable and unstable manifolds from a hyperbolic fixed point ...
Power switching in hybrid coherent couplers
(1997)
We report on a theoretical and numerical investigation of the switching of power in new hybrid models of nonlinear coherent couplers consisting of optical slab waveguides with various orders of nonlinearity. The first model ...
Robust tori-like Lagrangian coherent structures
(Elsevier B.V., 2012-12-15)
In general the term "Lagrangian coherent structure" (LCS) is used to make reference about structures whose properties are similar to a time-dependent analog of stable and unstable manifolds from a hyperbolic fixed point ...
In situ reactor to image catalysts at work in three-dimensions by Bragg coherent X-ray diffraction
(2019-10-01)
A new reactor dedicated to high temperature Bragg coherent X-ray diffraction imaging (Bragg CDI) of heterogeneous catalysts at atmospheric pressure has been developed. It allows direct visualisation of the shape, surface ...
Resolvent modelling of near-wall coherent structures in turbulent channel flow
(2020-10-01)
Turbulent channel flow was analysed using direct numerical simulations at friction Reynolds numbers Reτ=180 and 550. The databases were studied using spectral proper orthogonal decomposition (SPOD) to identify dominant ...
GPS Diffractive Reflectometry: Footprint of a Coherent Radio Reflection Inferred From the Sensitivity Kernel of Multipath SNR
(Ieee-inst Electrical Electronics Engineers Inc, 2016-10-01)
The validation of remote sensing environmental estimates requires knowledge of their spatial extent and resolution. Here, we consider coherent radio reflections routinely observed in ground-based global positioning system ...
Mitigation of nonlinear phase noise in single-channel coherent 16-QAM systems employing logistic regression
(2021-09-01)
We propose and analyze a classifier based on logistic regression (LR) to mitigate the impact of nonlinear phase noise (NPN) caused by Kerr-induced self-phase-modulation in digital coherent systems with single-channel ...
