    TRAPPIST-1 d: Exo-Venus, Exo-Earth, or Exo-Dead? by M. J. Way

    Published 2025-01-01
    “…Assuming that TRAPPIST-1 d still retains a substantial atmosphere, we demonstrate via a series of 3D general circulation model experiments using a dynamic ocean that the planet could reside within the habitable zone in a narrow parameter space. At the same time, it could also be an exo-Venus- or exo-Dead-type world or in transition between between one of these. …”

    Expandable Orbit Decay Prediction Using Continual Learning by Junhua He, Hua Wang, Haitao Wang, Xuankun Fang, Chengyi Huo

    Published 2024-01-01
    “…Higher requirements for precise orbit decay prediction (PODP) technology are requested, which provides accurate state references for orbit maintenance and necessary database for space situational awareness. The effectiveness of the traditional orbital prediction method for PODP is limited by inaccurate estimation of the spacecraft’s physical parameters and space environments. …”

    L’habitation maya by Fabienne de Pierrebourg, Marie-Charlotte Arnauld, Helios Figuerola, Jean-Michel Hoppan, Olivier Le Guen, Perla Petrich

    Published 2012-12-01
    “…In this preliminary research, which makes use of archaeological, epigraphic and ethnological information, we present certain arguments showing a linguistic and conceptual continuity in the Mayan dwelling as a delimited space. The visible and invisible boundaries that temporarily or permanently enclose or divide up its space seem quite similar in the various regions and periods considered. …”
