Van der Waals interaction between an atom with spherical plasma shell [PDF]
, 2011 We consider the van der Waals energy of an atom near the infinitely thin sphere with finite conductivity which model the fullerene. We put the sphere into spherical cavity inside the infinite dielectric media, then calculate the energy of vacuum ...

Onset of Inertial Magnetoconvection in Rotating Fluid Spheres
Fluids, 2021 The onset of convection in the form of magneto-inertial waves in a rotating fluid sphere permeated by a constant axial electric current is studied in this paper.

Sustainability, 2019 The promotion of pro-environmental behavior is regarded as very important in solving environmental problems. The Value-Belief-Norm (VBN) theory usually emphasizes internal factors; however, we have transformed this theory by including the environmental ...

Serbian Astronomical Journal, 2020 I review the origins and development of the idea of Dyson spheres, their purpose, their engineering, and their detectability. I explicate the ways in which the popular imagining of them as monolithic objects would make them dynamically unstable under gravity and radiation pressure, and mechanically unstable to buckling.

Flat Space Amplitudes and Conformal Symmetry of the Celestial Sphere [PDF]
, 2016 The four-dimensional (4D) Lorentz group $SL(2,\mathbb{C})$ acts as the two-dimensional (2D) global conformal group on the celestial sphere at infinity where asymptotic 4D scattering states are specified.

My Private Sky. The Metamorphosis of Domesticity and its Political Meanings in the 20th Century
Scienza & Politica, 2022 During the 20th century, the format of domestic life became an explicit object of functional reworking and rewriting. Thanks to the industrialisation processes that affected it, the home entered the era of its technical reproducibility, becoming a ...

Quasisymmetric parametrizations of two-dimensional metric spheres [PDF]
, 2001 We study metric spaces homeomorphic to the 2-sphere, and find conditions under which they are quasisymmetrically homeomorphic to the standard 2-sphere. As an application of our main theorem we show that an Ahlfors 2-regular, linearly locally contractible

Controlled generation of higher-order Poincaré sphere beams from a laser [PDF]
Nature Photonics, 2015 The angular momentum of light can be described by positions on a higher-order Poincaré sphere, where superpositions of spin and orbital angular momentum states give rise to laser beams that have many applications, from microscopy to materials processing.
