Polarization Swings Reveal Magnetic Energy Dissipation in Blazars [PDF]
, 2015 The polarization signatures of the blazar emissions are known to be highly variable. In addition to small fluctuations of the polarization angle around a mean value, sometimes large (> 180^o) polarization angle swings are observed. We suggest that such p

What Does Intarsia Say? Materiality and Spirituality in the Urbino Studiolo☆
Renaissance Studies, EarlyView.Abstract Upon entering the Urbino studiolo of Federico da Montefeltro, the visitor is struck by a material‐charged environment. Surprisingly, only a few scholars have addressed one prominent aspect of the decorative scheme, namely, the feature of intarsia as a medium. Even so, it remains on the sidelines of the discussion.
