Earth rotation based on the celestial coordinates of the celestial intermediate pole. I, The Dynamical equations. [PDF]

, 2005
We present a study of the Earth’s rotational motion in terms of the Earth Orientation Parameters (EOP) of the new paradigm that is recommended by the IAU 2000 resolutions to transform between the celestial and terrestrial reference systems.

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

High-frequency Earth rotation parameters estimated from VLBI observations during CONT campaigns

Earth, Planets and Space
The Desai–Sibois high-frequency Earth rotation parameter (HF-ERP) model provides one of the most detailed descriptions of diurnal and sub-diurnal variability up to date.

Earth Rotation and Gravity Field Parameters from Satellite Laser Ranging [PDF]

, 2014
We present the results from a simultaneous estimation of the gravity field, Earth rotation parameters, and station coordinates from combined SLR solutions incorporating up to nine geodetic satellites: LAGEOS-1/2, Starlette, Stella, AJISAI, Beacon-C ...

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Reply to comment on “Dual-quaternion-based iterative algorithm of the three dimensional coordinate transformation”

Earth, Planets and Space
Our recent paper (Zeng et al. in Earth Planets Sp 76:20, 2024) presented a Dual Quaternion Algorithm (DQA) of 3D coordinate transformation in weighted total least squares (WTLS). Zeng et al.

Evaluating the accuracy of earth rotation parameters based on the BDS observations

Geodesy and Geodynamics
The BeiDou satellite system (BDS) has progressed with the full operationalization of the second-generation regional system (BDS-2) and the third-generation global system (BDS-3).

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Earth Rotation Parameters Derived from BDS-3 New Signals B1C/B2a Dual-Frequency Combination Observations

Remote Sensing
The Earth rotation parameters (ERP) play a crucial role in defining the global reference frame and the Global Navigation Satellite System (GNSS) is one of the important tools used to obtain ERP, including polar motion (PM), its rates, and length of day ...
