Empirical Earth rotation model: a consistent way to evaluate Earth orientation parameters [PDF]
in Geodetic Reference Frames, ed. by H. Drewes, Springer-Verlag,
2009, p. 233, 2006 It is customary to perform analysis of the Earth's rotation in two steps: first, to present results of estimation of the Earth orientation parameters in the form of time series based on a simplified model of variations of the Earth's rotation for a short period of time, and then to process this time series of adjustments by applying smoothing, re ...

Neutron-gravity interferometry experiment: testing Earth's rotating frequency fluctuations via neutron Berry's phases due to spin-rotation couplings [PDF]
arXiv, 2003 Neutron spin can be coupled to the Earth's rotating frequency. Once if the Earth's rotating frequency is time-dependent, then the neutron will acquire a Berry's topological phase (cyclic adiabatic geometric phase). So, a potential method to investigate the Earth's time-varying rotating frequency by measuring the phase difference between geometric ...

On the planetary acceleration and the rotation of the Earth [PDF]
Astrophysics and Space Science, 2008 We have developed a model for the Earth rotation that gives a good account (data) of the Earth astronomical parameters. These data can be compared with the ones obtained using space-base telescopes. The expansion of the universe has an impact on the rotation of planets, and in particular, the Earth.

The road toward a general relativistic metric inside the Earth and its effect on neutrino travel from CERN to GRAN-SASSO Laboratory [PDF]
arXiv, 2012 In a first attempt to describe the effect on neutrino travel inside the Earth caused by general relativity in the case of a dense Earth, we have neglected the Earth's rotation, the Earth's ellipticity and also the surface terrain variation, nevertheless we have focused our attention on the density description of the Earth interior provided by geophysic'

Main effects of the Earth's rotation on the stationary states of ultra-cold neutrons [PDF]
, 2007 The relativistic corrections in the Hamiltonian for a particle in a uniformly rotating frame are discussed. They are shown to be negligible in the case of ultra-cold neutrons (UCN) in the Earth's gravity.

ESD Ideas: A 6-year oscillation in the whole Earth system? [PDF]
Earth System Dynamics, 2023 An oscillation of about 6 years has been reported in Earth's fluid core motions, magnetic field, rotation, and crustal deformations. Recently, a 6-year cycle has also been detected in several climatic parameters (e.g., sea level, surface temperature ...

Why the Mw 6 parkfield earthquake expected in the 1985–1993 interval was postponed till 2004?
Geomatics, Natural Hazards & Risk, 2022 The earthquake prediction released by USGS in 1985 to the public stated that there was an Mw6.0 earthquake occurring in the Parkfield area by January 1993 with a 95% chance. This prediction has proved unsuccessful.

地球与行星物理论评, 2023 The universal time (UT1-UTC) and length of day change (ΔLOD) are two parameters that describe the Earth's rotation rate variations. UT1-UTC is typically used in space projects, whereas ΔLOD is used for scientific investigations.

Zonal concentration of some geophysical process intensity caused by tides and variations in the Earth's rotation velocity [PDF]
Advances in Geosciences, 2014 We analyzed what kind of fundamental physical phenomena can be responsible for the generation of the anomalous latitudinal zones of the seismic activity, and the hotspots, and some other geophysical processes.

Geomatics, Natural Hazards & Risk, 2021 For earthquakes (M ≥ 2.0) occurring in and around the aftershock zone of the M7.1 Ridgecrest earthquake between January 2000 and June 2019, we analyzed the correlation between the phase of Earth's rotation and the occurrence of earthquakes.
