Predicting the relativistic periastron advance of a binary without curving spacetime

, 2017
Relativistic Newtonian Dynamics, the simple model used previously for predicting accurately the anomalous precession of Mercury, is now applied to predict the periastron advance of a binary.

On incorporating post-Newtonian effects in N-body dynamics

, 2014
The increasing role of general relativity in the dynamics of stellar systems with central massive black holes and in the evolution of hierarchical triple systems inspires a close examination of how post-Newtonian effects are incorporated into N-body ...

GPU‐Accelerated Lattice Boltzmann Simulations of Power‐Law Non‐Newtonian Fluid Flow in a Diagonally Driven Cavity Using D3Q27 MRT‐LBM

Engineering Reports
The study examines the flow dynamics of power‐law non‐Newtonian fluids in a cubic cavity with a top lid‐driven diagonally‐driven diagonally using the D3Q27 multiple‐relaxation‐time (MRT) lattice Boltzmann method (LBM). This situation frequently occurs in

Modified Newtonian Dynamics: A Falsification of Cold Dark Matter

Advances in Astronomy, 2009
The only viable alternative to dark matter is one in which Newtonian dynamics or gravity breaks down in the limit of low accelerations, as in modified Newtonian dynamics (MONDs).

The Magellanic Stream in Modified Newtonian Dynamics

, 2006
The dynamics of the Magellanic Stream (MS) as a series of clouds extending from the Magellanic Clouds (MCs) to the south Galactic pole is affected by the distribution and the amount of matter in the Milky Way. We calculate the gravitational effect of the

Dynamic simulation of non-Newtonian boundary layer flow: An enhanced exponential time integrator approach with spatially and temporally variable heat sources

Open Physics
Scientific inquiry into effective numerical methods for modelling complex physical processes has led to the investigation of fluid dynamics, mainly when non-Newtonian properties and complex heat sources are involved.

Non-Newtonian flow effects in supercooled water

Physical Review Research, 2020
The viscosity of supercooled water has been a subject of intense study, in particular with respect to its temperature dependence. Much less is known, however, about the influence of dynamical effects on the viscosity in its supercooled state.

Cosmology with modified Newtonian dynamics (MOND) [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
It is well-known that the application of Newtonian dynamics to an expanding spherical region leads to the correct relativistic expression (the Friedmann equation) for the evolution of the cosmic scale factor. Here, the cosmological implications of Milgrom's modified Newtonian dynamics (MOND) are considered by means of a similar procedure.
