Detection of significant climatic precession variability in early Pleistocene glacial cycles
Earth and Planetary Science Letters, 2020 Despite having a large influence on summer insolation, climatic precession is thought to account for little variance in early Pleistocene proxies of ice volume and deep-water temperature.

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 ...

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.

Precession of Isolated Neutron Stars II: Magnetic Fields and Type II Superconductivity [PDF]
, 2002 We consider the physics of free precession of a rotating neutron star with an oblique magnetic field. We show that if the magnetic stresses are large enough, then there is no possibility of steady rotation, and precession is inevitable.

Precession Motion in Levitated Optomechanics. [PDF]
Physical Review Letters, 2018 We investigate experimentally the dynamics of a nonspherical levitated nanoparticle in a vacuum. In addition to translation and rotation motion, we observe the light torque-induced precession and nutation of the trapped particle. We provide a theoretical

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 ...

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

Comparing Post-Newtonian and Numerical-Relativity Precession Dynamics [PDF]
, 2015 Binary black-hole systems are expected to be important sources of gravitational waves for upcoming gravitational-wave detectors. If the spins are not colinear with each other or with the orbital angular momentum, these systems exhibit complicated ...

Spin precession in anisotropic cosmologies [PDF]
, 2016 We consider the precession of a Dirac particle spin in some anisotropic Bianchi universes. This effect is present already in the Bianchi-I universe. We discuss in some detail the geodesics and the spin precession for both the Kasner and the Heckmann ...
