    Phosphorylation and Circadian Molecular Timing by Andrea Brenna, Andrea Brenna, Urs Albrecht

    Published 2020-11-01
    “…Through their adaptability to environmental changes, they synchronize physiological responses to environmental challenges that occur within a sidereal day. The precision of this circadian system is assured by many post-translational modifications (PTMs) that occur on the protein components of the circadian clock mechanism. …”

    Asymptotic Solutions for Equatorial Waves on Venus by Javier Peralta

    Published 2023-02-01
    “…Due to its particularly long sidereal day (243 terrestrial days against 24 h for the Earth), the Venusian waves must be described with the momentum equations for a cyclostrophic regime, but efforts to derive analytical wave solutions have been scarce. …”

    Design and validation of an adaptive CubeSat transmitter system by Jaswar, F., Al-Samman, A. M., Abdul Rahman, T., Ahmad, Y. A.

    Published 2019
    “…Nevertheless, the LEO satellite does not have an orbital velocity that equates to one sidereal day. Therefore, the ground station antenna views the satellite at different elevation angles which result in varied propagation path lengths. …”

    Search for anisotropic gravitational-wave backgrounds using data from Advanced LIGO and Advanced Virgo’s first three observing runs

    Published 2022
    “…For the first time, we include Virgo data in our analysis and run our search with a new efficient pipeline called {\tt PyStoch} on data folded over one sidereal day. We use gravitational-wave radiometry (broadband and narrow band) to produce sky maps of stochastic gravitational-wave backgrounds and to search for gravitational waves from point sources. …”

    Geosynchronous Satellite Maneuver Classification and Orbital Pattern Anomaly Detection via Supervised Machine Learning by Roberts, Thomas González

    Published 2022
    “…Due to the nature of the geosynchronous (GEO) orbital regime, where space objects orbit the Earth once per sidereal day, GEO satellites can appear fixed to a position in the sky when observed from the Earth’s surface. …”

    Venus express: Highlights of the nominal mission by Titov, D, Svedhem, H, Taylor, F, Barabash, S, Bertaux, J, Drossart, P, Formisano, V, Haeusler, B, Korablev, O, Markiewicz, W, Nevejans, D, Paetzold, M, Piccioni, G, Sauvaud, J, Zhang, T, Witasse, O, Gerard, J, Fedorov, A, Sanchez-Lavega, A, Helbert, J, Hoofs, R

    Published 2009
    “…The nominal mission lasted from June 4, 2006 till October 2, 2007, which corresponds to about two Venus sidereal days. Here we present an overview of the main results of the nominal mission, based on a set of papers recently published in Nature, Icarus, Planetary and Space Science, and Geophysical Research Letters. © 2009 Pleiades Publishing, Ltd.…”

    Pass-by-Pass Ambiguity Resolution in Single GPS Receiver PPP Using Observations for Two Sequential Days: An Exploratory Study by Ruijie Xi, Qusen Chen, Xiaolin Meng, Panos Psimoulis, Weiping Jiang, Caijun Xu

    Published 2021-09-01
    “…In this study, we carried out an exploratory study to use the “pass-by-pass” ambiguity resolution by differencing the undifferenced ambiguity candidates for two adjacent passes in sidereal days for a single Global Positioning System (GPS) receiver static Precise Point Positioning (PPP). …”

    Estimation of free core nutation parameters and availability of computing options by Weiwei Yang, Xiaoming Cui, Jianqiao Xu, Qingchao Liu, Ming Qin

    Published 2024-01-01
    “…The stacking method, which results in a variation of 0.24–5 sidereal days (SDs) in the FCN period (T) and 103-104 in the quality factor (Q) due to the selection of the weighting function and the ocean tide model (OTM), can effectively suppress this influence. …”
