DETERMINATION OF THE ROTATION MEASURE VALUE SIGN WHEN RECEIVING A SINGLE LINEAR POLARIZATION OF THE PULSAR RADIO EMISSION [PDF]

Radio Physics and Radio Astronomy, 2020
Purpose: The studies of pulsars allow enriching our knowledge in determination of parameters of both the exotic electron-positron plasma in the pulsar magnetosphere with strong magnetic field and the ordinary ion-electron plasma of the interstellar ...

Determining and Evaluating the Hydrological Signal in Polar Motion Excitation from Gravity Field Models Obtained from Kinematic Orbits of LEO Satellites

Remote Sensing, 2019
This study evaluates the gravity field solutions based on high-low satellite-to-satellite tracking (hl-SST) of low-Earth-orbit (LEO) satellites: GRACE, Swarm, TerraSAR-X, TanDEM-X, MetOp-A, MetOp-B, and Jason 2, by converting them into hydrological polar

A possible interrelation between Earth rotation and climatic variability at decadal time-scale

Geodesy and Geodynamics, 2016
Using multichannel singular spectrum analysis (MSSA) we decomposed climatic time series into principal components, and compared them with Earth rotation parameters. The global warming trends were initially subtracted.

Sensitivity limit investigation of a Sagnac gyroscope through linear regression analysis

European Physical Journal C: Particles and Fields, 2021
The sensitivity to angular rotation of the top class Sagnac gyroscope GINGERINO is carefully investigated with standard statistical means, using 103 days of continuous operation and the available geodesic measurements of the Earth angular rotation rate ...

Seismic active earth pressures on rigid retaining walls under RT mode considering rotation of principal stresses

Yantu gongcheng xuebao, 2018
Considering the rotation of the principal stresses, new formulae for seismic active pressures on rigid retaining walls under rotation about top (RT mode) are derived by the pseudo-static method.

Assimilation of Earth rotation parameters into a global ocean model: excitation of polar motion [PDF]

Nonlinear Processes in Geophysics, 2011
The oceanic contribution to Earth rotation anomalies can be manifold. Possible causes are a change of total ocean mass, changes in current speed or location and changes in mass distribution.

The deforming and rotating Earth – A review of the 18th International Symposium on Geodynamics and Earth Tide, Trieste 2016

Geodesy and Geodynamics, 2018
The 18th International Symposium on Geodynamics and Earth Tides 2016 covered phenomena that generate temporal variations in geodetic and geophysical observations. In calculating the stress field for Earth tides, the observed geodetic response is used for

Understanding the effect of revolution and rotation of the earth on prayer times using accurate times

Ulul Albab: Jurnal Studi dan Penelitian Hukum Islam, 2020
Prayer time is closely related to the position of the Sun toward the Earth. The position of the Sun against the Earth is affected by the revolution and rotation of the Earth.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
