International trade without CES : estimating translog gravity [PDF]
, 2012 This paper derives a micro-founded gravity equation based on a translog demand system that allows for flexible substitution patterns across goods. In contrast to the standard CES-based gravity equation, translog gravity generates an endogenous trade cost

The Unexpected Fractal Signatures in Fibonacci Chains
Fractal and Fractional, 2019 In this paper, a new fractal signature possessing the cardioid shape in the Mandelbrot set is presented in the Fourier space of a Fibonacci chain with two lengths, L and S, where L / S = ϕ . The corresponding pointwise dimension is 1.7.

Is Gravity an Entropic Force? [PDF]
, 2011 The remarkable connections between gravity and thermodynamics seem to imply that gravity is not fundamental but emergent, and in particular, as Verlinde suggested, gravity is probably an entropic force.

, 2023 I often hear scientists say that gravity is a purely attractive force. In his 1967 article “GRAVITATION”, World Book Encyclopedia’s Robert F. Paton M.Sc., Ph.D. presents a view closer in time to General Relativity’s formulation when he writes – “Einstein says that bodies do not attract each other at a distance.

Journal of Physics A: Mathematical and General, 2006 By attaching five (complex) anticommuting property coordinates to the four (real) commuting space-time ones, it is possible to accommodate all the known fundamental particles in their three generations. A general relativistic extension to space-time-property can be carried out such that the gauge fields find their place in the space-property sector and

Dual little strings from F-theory and flop transitions
Journal of High Energy Physics, 2017 A particular two-parameter class of little string theories can be described by M parallel M5-branes probing a transverse affine A N − 1 singularity. We previously discussed the duality between the theories labelled by (N, M) and (M, N).

Parallel Processing Letters, 2000 We consider the problem of establishing gravity in cellular automata. In particular, when cellular automata states can be partitioned into empty, particle, and wall types, with the latter enclosing rectangular areas, we desire rules that will make the particles fall down and pile up on the bottom of each such area.

Quantum Gravity: Motivations and Alternatives [PDF]
, 2009 The mutual conceptual incompatibility between General Relativity and Quantum Mechanics / Quantum Field Theory is generally seen as the most essential motivation for the development of a theory of Quantum Gravity.

Entropy, 2012 The effect of gravity upon changes of the entropy of a gravity-dominated system is discussed. In a universe dominated by vacuum energy, gravity is repulsive, and there is accelerated expansion. Furthermore, inhomogeneities are inflated and the universe approaches a state of thermal equilibrium. The difference between the evolution of the cosmic entropy

, 2010 The observable universe could be a 1+3-surface (the “brane”) embedded in a 1+3+d-dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk.
