In order to discover strategies that could be used to attract clicks, we extracted features from the text of the news headlines related to the sentiment polarity of the headline.  ...  We discovered that the sentiment of the headline is strongly related to the popularity of the news and also with the dynamics of the posted comments on that particular news.  ...  Another application, namely Magnet News (Reis et al., 2014) , is a tool that separates positive from negative news in popular newspapers and allows readers to choose which pieces of news to read according  ...

Classical-Field Theory of Electron Waves as a Polarized Radiation Probe of Magnetic Surfaces [article]

D. C. Hatton, J. A. C. Bland
2002 arXiv   pre-print
Recently, there has been a revival of interest in mechanisms for changing the spin polarization of an electron beam on transmission through, or reflection from, a magnetic surface.  ...  An understanding of these mechanisms would allow the use of an electron beam as a polarized radiation probe for magnetic characterization, like light in MOKE and neutrons in PNR.  ...  You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies.  ...

The Interpretation of Magnetograph Results: The Formation of Absorption Lines in a Magnetic Field [chapter]

J. O. Stenflo
1971 Solar Magnetic Fields  
Representation of Polarized Light The vibration of the electrical vector of polarized light propagating along the z-axis in an xyz coordinate system can be described by and (1) £y = f2 COS (cot -£ 2 ),  ...  Special attention is paid to the inhomogeneous nature of the solar atmosphere. The properties of magnetic filaments are reviewed.  ...  One interesting feature of Figure 6 is that it opens a new possibility to test the idea of that the magnetic flux outside active regions is what they call 'quantized'.  ...

New light on EuO thin films: preparation, transport, magnetism and spectroscopy of a ferromagnetic semiconductor [article]

P.G. Steeneken
2012 arXiv   pre-print
This PhD thesis presents a study of the ferromagnetic semiconductor EuO. Chapter 1 gives a general introduction, chapter 2 presents a calculation of the magneto-optical spectrum.  ...  Chapter 8 deals with the nature of doping in the high-Tc cuprates. This work was supervised by G.A. Sawatzky and L.H. Tjeng.  ...  From a technological perspective, the exponentially increasing data densities on magnetic recording media require large enhancements of the sensitivity of magnetic reading heads, which have led to a strong  ...

Photon-axion conversion, magnetic field configuration, and polarization of photons

Emi Masaki, Arata Aoki, Jiro Soda
2017 Physical Review D  
We study the evolution of photon polarization during the photon-axion conversion process with focusing on the magnetic field configuration dependence.  ...  Remarkably, we analytically obtain the asymptotic values of the variance of polarization in the conventional model.  ...  In particular, we examine to what extent the result depends on the configuration of magnetic fields.  ...

Magnetic control of polariton spin transport

D. Caputo, E. S. Sedov, D. Ballarini, M. M. Glazov, A. V. Kavokin, D. Sanvitto
2019 Communications Physics  
We show the change of the spin-beat frequency, the suppression of the optical spin Hall effect, and the rotation of the polarization pattern by the magnetic field.  ...  Here we demonstrate experimentally the full control of the polarization dynamics of a propagating exciton-polariton condensate in a planar microcavity by using a magnetic field applied in the Voigt geometry  ...  This additional feature of polaritons significantly broadens the range of their possible applications to include what is known under the name of spinoptronics.  ...
