The Evolution of Polarization in Online Conversation: Twitter Users’ Opinions about the COVID-19 Pandemic Become More Politicized over Time

open access: yesHuman Behavior and Emerging Technologies, 2023
Political polarization on social media has been extensively studied. However, most research has examined polarization about topics that have preexisting associations with ideology, while few studies have tracked the onset of polarization about novel ...

Polarization Coupling Based on Faraday Effect in Whispering-Gallery-Mode Resonator

open access: yesIEEE Photonics Journal, 2020
In this article, we study the polarization coupling in a Faraday magnetooptical microcavity. Due to Faraday effect, the polarization coupling can be achieved between the intrinsic left and right elliptically-polarized modes.

Probing the Large Faraday Rotation Measure Environment of Compact Active Galactic Nuclei

open access: yesGalaxies, 2018
Knowing how the ambient medium in the vicinity of active galactic nuclei (AGNs) is shaped is crucial to understanding generally the evolution of such cosmic giants as well as AGN jet formation and launching.

Birefringence-derived artifact in optical coherence tomography imaging of the lamina cribrosa in eyes with glaucoma

open access: yesScientific Reports, 2023
We investigated birefringence-derived artifacts that potentially mimic focal defects of the lamina cribrosa (focal LC defects) in optical coherence tomography (OCT) imaging of eyes with glaucoma.

Lambda polarization feasibility study at BM@N

open access: yesEPJ Web of Conferences, 2017
Heavy strange objects (hyperons) could provide essential signatures of the excited and compressed baryonic matter. At NICA, it is planned to study hyperons both in the collider mode (MPD detector) and the fixed-target one (BM@N setup).

Validation study of Polar V800 accelerometer [PDF]

open access: yesAnnals of Translational Medicine, 2016
The correct quantification of physical activity (PA) and energy expenditure (EE) in daily life is an important target for researchers and professionals. The objective of this paper is to study the validity of the Polar V800 for the quantification of PA and the estimation of EE against the ActiGraph (ActiTrainer) in healthy young adults.Eighteen ...

Polar nephelometer for atmospheric particulate studies [PDF]

open access: yesApplied Optics, 1980
A unique polar nephelometer was designed and constructed for the measurement of atmospheric particulate characteristics. The nephelometer produces visible light from a self-contained laser to irradiate an air sample drawn into the instrument. The light scattered from the particulates and molecules in the sample is detected as a function of scattering ...

Polarization studies of rotating radio transients [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
ABSTRACT We study the polarization properties of 22 known rotating radio transients (RRATs) with the 64-m Parkes radio telescope and present the Faraday rotation measures (RMs) for the 17 with linearly polarized flux exceeding the off-pulse noise by 3σ.

Characterizing polarization in online vaccine discourse-A large-scale study.

open access: yesPLoS ONE, 2022
Vaccine hesitancy is currently recognized by the WHO as a major threat to global health. Recently, especially during the COVID-19 pandemic, there has been a growing interest in the role of social media in the propagation of false information and fringe ...
