Depolarization Measurement through a Single-Mode Fiber-Based Endoscope for Full Mueller Endoscopic Polarimetric Imaging

open access: yesPhotonics, 2023
Coupled to endoscopic techniques, Mueller polarimetry has been proven to be promising for early detection of certain diseases which affect biological tissues of inner organs.

The effect of relative humidity on the polarization Mueller matrix under the oil smoke environment

open access: yesFrontiers in Physics, 2023
For the variation of the polarized Mueller matrix of oil smoke particles under different relative humidity levels, the polarized single scattering characteristics of oil smoke particles are studied by using the Mie scattering theory, and the multiple ...

Active role of capillary pericytes during stimulation-induced activity and spreading depolarization

open access: yesBrain : a journal of neurology, 2018
Spreading depolarization is assumed to be the mechanism of migraine with aura, which is accompanied by an initial predominant hyperaemic response followed by persistent vasoconstriction.

Semiconductor/relaxor 0–3 type composites without thermal depolarization in Bi0.5Na0.5TiO3-based lead-free piezoceramics

open access: yesNature Communications, 2015
Commercial lead-based piezoelectric materials raised worldwide environmental concerns in the past decade. Bi0.5Na0.5TiO3-based solid solution is among the most promising lead-free piezoelectric candidates; however, depolarization of these solid solutions

Tuning of the depolarization field and nanodomain structure in ferroelectric thin films. [PDF]

open access: yesNano letters (Print), 2014
The screening efficiency of a metal-ferroelectric interface plays a critical role in determining the polarization stability and hence the functional properties of ferroelectric thin films.

Extension and Limits of Depolarization-Fringe Contrast Roughness Method in Sub-Micron Domain

open access: yesSensors, 2021
To guarantee quality standards for the industry, surface properties, particularly those of roughness, must be considered in many areas of application. Today, several methods are available on the market, but some damage the surface to be tested as they ...

SU(2)-invariant depolarization of quantum states of light [PDF]

open access: yesPhys. Rev. A 88, 052120 (2013), 2013
We develop an SU(2)-invariant approach to the depolarization of quantum systems as the effect of random unitary SU(2) transformations. From it we derive an SU(2)-invariant Markovian master equation. This is applied to several quantum states examining whether nonclassical states are more sensible to depolarization than the classical ones.

Spreading depolarization in the brainstem mediates sudden cardiorespiratory arrest in mouse SUDEP models

open access: yesScience Translational Medicine, 2015
Ion channel mutations that cause epilepsy also predispose the immature brainstem to generate a depolarizing, tsunami-like wave that leads to autonomic collapse and death.

Shifts in Phytoplankton Community Structure Across an Anticyclonic Eddy Revealed From High Spectral Resolution Lidar Scattering Measurements

open access: yesFrontiers in Marine Science, 2020
Changes in airborne high spectral resolution lidar (HSRL) measurements of scattering, depolarization, and attenuation coincided with a shift in phytoplankton community composition across an anticyclonic eddy in the North Atlantic. We normalized the total
