Does the usage of social media make individuals more polarized? Previous studies have shown that political use of the internet does make individuals more likely to politically participate, but little academic work has looked at the dynamic of ideology and the social media usage, despite the increase of social media usage in everyday life. This study uses Facebook, Twitter, Instagram, Reddit, YouTube, Snapchat, and TikTok to see if social media users are more polarized, and which ideological groups are more polarized on social media. Moderates are included to differentiate if there is a difference. This study analyzed data from the American National Election Survey (ANES) of 2020 to analyze regression models between the social media platforms, and the different groups of polarization. Evidence was found that liberal polarization was correlated with Twitter, Instagram, and Reddit usage. Counterevidence was found of conservative polarization and Reddit and Snapchat usage. When moderates are included, polarization was found in Twitter, Reddit, and YouTube usage.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / This paper describes a ferrite antenna that can produce any polarization on the Poincaré sphere over the frequency range of 9.0 to 11.4 GHz by utilizing Faraday rotation and a quarter-wavelength phase shifter. All possible polarizations of the electromagnetic wave are achievable with this antenna which includes linear, circular and elliptical polarizations. Any tilt angle of elliptical polarization and any orientation of the linear polarization can be achieved as well. The polarization of the ferrite antenna can be electronically switched to a different polarization instantly without the use of moving parts. An automatic data acquisition system was designed and built to fully analyze the antenna' s characteristics.

The differential Optical Transfer Function (dOTF) is a focal plane wavefront sensing method that uses a diversity in the pupil plane to generate two different focal plane images. The difference of their Fourier transforms recovers the complex amplitude of the pupil down to the spatial scale of the diversity. We produce two simultaneous PSF images with diversity using a polarizing filter at the edge of the telescope pupil, and a polarization camera to simultaneously record the two images. Here we present the first on-sky demonstration of polarization dOTF at the 1.0m South African Astronomical Observatory telescope in Sutherland, and our attempt to validate it with simultaneous Shack-Hartmann wavefront sensor images.

The molecules in many substances are know to undergo at characteristic temperatures a change in their rotational freedom in the solid state, signifying either a change in structure of the material of the onset of limited rotation of the molecule about some symmetry axis. The purpose of this research was to determine from dielectric constant measurements over the 100°K-420°K temperature range whether or not the organic free radical galvinoxyl and its diamagnetic parent molecule, dihydroxydiphenylmethane, undergo any such transitions.
