Atmospheric acceleration and Earth-expansion deceleration of the Earth rotation
Geodesy and Geodynamics, 2017 Previous studies suggest that tidal friction gives rise to the secular deceleration of the Earth rotation by a quantity of about 2.25 ms/cy. Here we just consider additional contributions to the secular Earth rotation deceleration. Atmospheric solar semi-

Deep Earth rotational seismology
Geophysical Journal International, 2023 SUMMARYRotational seismology opens a new avenue to study the deep interior of the Earth. Using data from the Wettzell Observatorium, Germany, where a ring laser gyroscope and a 3-component translational broadband seismometer are co-located, we report the presence of clear S, ScS and SdS signals on both rotational and translational seismograms.

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.

Test of gravitomagnetism with satellites around the Earth
, 2019 We focus on the possibility of measuring the gravitomagnetic effects due to the rotation of the Earth, by means of a space-based experiment that exploits satellites in geostationary orbits.

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 ...

Albedo heterogeneity on the surface of (1943) Anteros [PDF]
, 2009 We have investigated the effect of rotation on the polarization of scattered light for the near-Earth asteroid (1943) Anteros using the Dual Beam Imaging Polarimeter on the University of Hawaii's 2.2 m telescope.

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Failure modes and inclined bearing capacity of a modified suction caisson in sand
Applied Ocean ResearchExperiments and simulations are undertaken on the bearing behavior of a modified suction caisson (MSC) in sand under inclined load. Results show that the MSC movement modes include forward rotation, backward rotation, translations mainly along the ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
