Post-truth conspiracism and the pseudo-public sphere

Frontiers in Communication
Rather than seeking to recuperate the ideal of a digital public sphere or lament its demise with the rise of social media platforms, in this paper I seek to identify the dangers of precisely this insistence to imagine the Internet as a public sphere.

On 1-index of Unstable Spacelike Hypersurfaces in Pseudo-Euclidean Spheres [PDF]

Sahand Communications in Mathematical Analysis, 2021
In mathematical physics, the stable hypersurfaces of constant mean curvature in pseudo-Euclidian spheres have been interested by many researchers on general relativity.

Computation of Structure and Electrical Resistivity of Liquid Na-Rb Alloys

East European Journal of Physics, 2022
The structure and electrical resistivity of Na1-xRbx binary alloys (where x = 0, 0.1, 0.2,…,1) are computed using Percus-Yevick (PY) equation, hard-sphere model and Faber-Ziman formula respectively.

Pseudo-Isotropic Centro-Affine Lorentzian Surfaces

Mathematics, 2020
In this paper, we study centro-affine Lorentzian surfaces M2 in ℝ3 which have pseudo-isotropic or lightlike pseudo-isotropic difference tensor. We first show that M2 is pseudo-isotropic if and only if the Tchebychev form T=0.

Investigation on the copper ion removal potential of a facile-fabricated foamed geopolymer sphere for wastewater remediation

Cleaner Materials, 2022
Heavy metal contamination is regarded as one of the most serious hazards to the environment and living organism. The scenario is exacerbating especially due to the continuous development.

Classifications of Canal Surfaces with the Gauss Maps in Minkowski 3-Space

Mathematics, 2020
In this work, we study the canal surfaces foliated by pseudo spheres S12 along a Frenet curve in terms of their Gauss maps in Minkowski 3-space. Such kind of surfaces with pointwise 1-type Gauss maps are classified completely.

Multiple Instagram Accounts and the Illusion of Freedom

Komunikator, 2022
This article is motivated by the phenomenon of the ownership of multiple accounts on Instagram among teenagers. Previous research mentioned that a second Instagram account is used to express oneself without worrying that the identity of the users will be

Features of the geometry of the five-dimensional pseudo-Euclidean space of index two [PDF]

E3S Web of Conferences
The article is devoted to the study of the geometry of subspaces of a five-dimensional pseudo-Euclidean space. This space is attractive because all kinds of semi-Euclidean, semi-pseudo-Euclidean, hyperbolic three-dimensional spaces with projective ...

The curious case of large-N expansions on a (pseudo)sphere

Nuclear Physics B, 2015
We elucidate the large-N dynamics of one-dimensional sigma models with spherical and hyperbolic target spaces and find a duality between the Lagrange multiplier and the angular momentum.

Strongly pseudo-convex CR space forms

Complex Manifolds, 2019
For a contact manifold, we study a strongly pseudo-convex CR space form with constant holomorphic sectional curvature for the Tanaka-Webster connection.
