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 ...

Considerations regarding the variability of Earth-Sun geometry and the climate variability in south-western Romania [PDF]
Riscuri şi Catastrofe, 2019 The variability of the Sun-Earth geometry is particularly high during the year due to the specific trajectory of the planet Earth around the Sun, the rotation motion of the Earth around its axis, the inclination of the rotation axis with respect to the ...

Effects of Huge Earthquakes on Earth Rotation and the length of Day
Terrestrial, Atmospheric and Oceanic Sciences, 2013 We calculated the co-seismic Earth rotation changes for several typical great earthquakes since 1960 based on Dahlen¡¦s analytical expression of Earth inertia moment change, the excitation functions of polar motion and, variation in the length of a day ...

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 ...
