Are Ocean Reanalyses Useful for Earth Rotation Research?
Earth and Space Science, 2023 Oceanic circulation and mass‐field variability play important roles in exciting Earth's wobbles and length‐of‐day changes (ΔΛ), on time scales from days to several years.

Earth Rotation and Its Parameters
, 2023 The Earth is under continuous influence of external attractive forces of the Sun and Moon, as well as an internal coupling between the Earth’s core and mantle and mass movements. This is why its rotation is not uniform.

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 ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

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 ...

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 ...
