Rainbow Gravity Corrections to the Entropic Force
Advances in High Energy Physics, 2018 The entropic force attracts a lot of interest for its multifunctional properties. For instance, Einstein’s field equation, Newton’s law of gravitation, and the Friedmann equation can be derived from the entropic force. In this paper, utilizing a new kind

Advanced Healthcare Materials, EarlyView.Packed hydrogel microfiber (PHM) materials consist of flexible and high aspect ratio hydrogel components that, as a bulk material, are simultaneously mechanically robust and dynamic. Cells cultured in or on PHM scaffolds can be influenced by topographical cues or interact with a dynamic environment that permits cell spreading and multicellular ...

Intra-industry Trade and the Gravity Equation: A Cournot-Ricardo Approach
East Asian Economic Review, 2000 This paper shows that Cournot competition in segmented markets generate both intra-industry trade and the gravity equation. The paper also demonstrates that the gravity equation holds if and only if the market shares of an exporting country do not depend

Scattering of Ricci scalar perturbations from Schwarzschild black holes in modified gravity
European Physical Journal C: Particles and Fields, 2017 It has already been shown that the gravitational waves emitted from a Schwarzschild black hole in f(R) gravity have no signatures of the modification of gravity from General Relativity, as the Regge–Wheeler equation remains invariant.

The cosmological constant as a boundary term
Journal of High Energy Physics, 2022 We compare the path integral for transition functions in unimodular gravity and in general relativity. In unimodular gravity the cosmological constant is a property of states that are specified at the boundaries whereas in general relativity the ...

The Gravity Equation in International Trade: An Explanation [PDF]
Journal of Political Economy, 2018 The gravity equation in international trade states bilateral exports are proportional to economic size, and inversely proportional to geographic distance. While the role of size is well understood, that of distance remains mysterious. I offer an explanation for the role of distance: If (i) the distribution of firm sizes is Pareto, (ii) the average ...

The significance of geographic location in island studies: a rejoinder [PDF]
Island Studies Journal, 2014 The results pointed out in the note ‘The significance of geographic location in island studies’ by McElroy & Lucas (2014) suggest that the economic performance of small islands is inversely related to their remoteness from the rest of the world and ...

Covariant Poisson’s equation in torsional Newton-Cartan gravity
Journal of High Energy Physics, 2019 We derive the covariant Poisson’s equation of (d + 1)-dimensional Newton-Cartan gravity with (twistless) torsion by applying the ‘non-relativistic conformal method’ introduced in [1].
