The Archimedean Quantum Gravity Equation

Gravity in this framework is not curvature, not a field, and not a particle‑mediated force. It is the pressure response of a discrete substrate whose flux is displaced by matter. A mass creates a local pressure deficit; surrounding higher‑pressure regions push inward, producing Archimedean acceleration.

Disentangling the relationships between denomination of origin regulatory councils activities and Spanish wineries' export performance

Agribusiness, EarlyView.
Abstract World markets for quality differentiated agri‐food products are highly competitive, presenting significant challenges for firms aiming to compete effectively. Government agencies and business organizations often implement various export promotion policies to address these challenges.

Parabolic equations for gravity and acousto-gravity waves

The Journal of the Acoustical Society of America, 1999
Parabolic equations for gravity and acousto-gravity waves are derived and implemented. The wave equations for these problems contain singularities at depths at which the buoyancy frequency equals the forcing frequency. One of the advantages of the parabolic equation solution is that it is easy to avoid numerical problems associated with the ...

The Gravity Equation

Abstract This chapter explores why bilateral trade flows are systematically related to countries’ economic size and geographic distance. Starting from empirical regularities—such as US and Swiss trade patterns—it shows that nations trade disproportionately with large and nearby economies, with extensions capturing borders, language ...

STOCHASTIC GRAVITY AND THE LANGEVIN-RAYCHAUDHURI EQUATION

International Journal of Modern Physics A, 2005
We treat the gravitational effects of quantum stress tensor fluctuations. An operational approach is adopted in which these fluctuations produce fluctuations in the focusing of a bundle of geodesics. This can be calculated explicitly using the Raychaudhuri equation as a Langevin equation.

On estimation of gravity equation: A cluster analysis

2014
This article questions the slope homogeneity in a gravity equation and proposes a partially heterogeneous framework for its estimation using panel data. We suggest to employ K-mean clustering to group countries according to the gravity equation variables. Further, the gravity model is estimated on these created homogeneous groups.
