Triadic resonances in nonlinear simulations of a fluid flow in a precessing cylinder
New Journal of Physics, 2015 We present results from three-dimensional nonlinear hydrodynamic simulations of a precession driven flow in cylindrical geometry. The simulations are motivated by a dynamo experiment currently under development at Helmholtz-Zentrum Dresden-Rossendorf in ...

Null and Timelike Geodesics near the Throats of Phantom Scalar Field Wormholes
Universe, 2020 We study geodesic motion near the throats of asymptotically flat, static, spherically symmetric traversable wormholes supported by a self-gravitating minimally coupled phantom scalar field with an arbitrary self-interaction potential.

The Impact of Orbital Precession on Air‐Sea CO2 Exchange in the Southern Ocean
Geophysical Research Letters, 2023 Orbital precession has been linked to glacial cycles and the atmospheric carbon dioxide (CO2) concentration, yet the direct impact of precession on the carbon cycle is not well understood.

Magnetic resonance signal [PDF]
Tehnika, 2019 The aim of this paper is to describe the magnetic resonance signal, how it occurs, what types of the signal there are and what they are used for. In order to achieve that goal, the original article of Isidor Isaak Raby was given, which disclosed the ...

Astronomical situation in the starry sky in the Neolithic-Chalcolithic in northern latitudes [PDF]
Archaeoastronomy and Ancient Technologies, 2014 The starry sky has been one of the central ancient sources of human knowledge - reflected in myths, religious practice, the arrangements of stone monuments, designs on stone and ceramics, and in the spatial orientation of ancient settlements.

Odessa Astronomical Publications, 2014 The light curves of EGS Ajisai with temporal resolution of 20 ms referred to the time scale UTC (GPS) with an error of at most 0.1 ms were obtained. The observed flashes are produced when the mirrors which cover the spinning satellite’s surface reflect ...

Maria Reiche's line to archaeoastronomy [PDF]
Archaeoastronomy and Ancient Technologies, 2013 Maria Reiche was a German mathematician and archaeologist that, from 1940, devoted her life to the study of the Nazca Lines, the most famous Peruvian geoglyphs, gaining recognition and preservation of them. Created by removing the upper most layer of the

Discussion of Quadrupole Precession [PDF]
American Journal of Physics, 1963 In this paper the motion of a nucleus with an intrinsic quadrupole moment in an external electrostatic field gradient is discussed from a classical point of view. It is shown that in the classical approximation the angular momentum may precess about the direction of strongest field gradient or about the direction of intermediate field gradient, but not

Spin Precession and Avalanches [PDF]
Physical Review Letters, 2007 In many magnetic materials, spin dynamics at short times are dominated by precessional motion as damping is relatively small. In the limit of no damping and no thermal noise, we show that for a large enough initial instability, an avalanche can transition to an ergodic phase where the state is equivalent to one at finite temperature, often above that ...
