A Guide for the Everyday Woman Surfer: How Surf Culture\u27s Patriarchy Marginalizes Ocean Lovers
Humans are naturally drawn to the water by wind and tide. It is a place of solace that we have a desire to know deeply, yet we have kept one another from experiencing it through biases that perpetuate inequality. White-supremacist hegemony has historically kept communities of color from coastlines, women from lineups, and queer communities from participating in surf culture. As more people from all social groups return to the water through surfing in the 20th century, surf culture needs to adapt to become more inclusive. This paper outlines surf culture\u27s historical transition into whiteness and how female beauty standards as well as LGBTQ+ communities are affected by white racial dominance and how surf culture is transitioning to become more inclusive
Spontaneous Conversion from Virtual to Real Photons in the Ultrastrong Coupling Regime
We show that a spontaneous release of virtual photon pairs can occur in a
quantum optical system in the ultrastrong coupling regime. In this regime,
which is attracting interest both in semiconductor and superconducting systems,
the light-matter coupling rate {\Omega}R becomes comparable to the bare
resonance frequency of photons {\omega}0. In contrast to the dynamical Casimir
effect and other pair creation mechanisms, this phenomenon does not require
external forces or time dependent parameters in the Hamiltonian.Comment: To appear on Phys. Rev. Let
Quantum complementarity of microcavity polaritons
We present an experiment that probes polariton quantum correlations by
exploiting quantum complementarity. Specifically, we find that polaritons in
two distinct idler-modes interfere if and only if they share the same
signal-mode so that "which-way" information cannot be gathered. The
experimental results prove the existence of polariton pair correlations that
store the "which-way" information. This interpretation is confirmed by a
theoretical analysis of the measured interference visibility in terms of
quantum Langevin equations
A remark on completely reducible near-rings
A characterization of the completely reducible (zerosymmetric right) near-rings which are the direct sum of their socle of type 2 and of their 2-radical is given
XAD2 resin in separation of phenolics
La résine XAD2 dans la séparation des composés phénoliquesOn a séparé les acides hydroxy cinnamyl tartriques, les acides phénoliques libres, les catéchines, les proanthocyanidines et les pigments libres et polymérisés du vin par adsorption sur la résine XAD2 suivie par l'élution avec des solvents organiques inertes. Les fractions ainsi obtenues sont analysées par CLHP
