A Self‐Supervised Framework for Space Object Behaviour Characterisation
Expert Systems, Volume 43, Issue 10, October 2026.ABSTRACT Foundation Models, which leverage large neural networks pre‐trained on unlabelled data before fine‐tuning for specific tasks, are increasingly being applied to specialised domains. Recent examples include ClimaX for climate and Clay for satellite Earth observation, but a Foundation Model for Space Object Behavioural Analysis (SOBA) has not yet

An Assisting Contact Electrification Strategy for Achieving Self‐Recoverable Mechanoluminescence
Advanced Science, Volume 13, Issue 52, 18 September 2026.ABSTRACT Self‐recoverable mechanoluminescence (ML) is a unique property of materials that can stably emit light under repeated stress, enabling new applications in smart sensing, displays, and wearable devices. However, self‐recoverable ML is very rare and only observed in a few active phosphors excited by piezoelectricity or contact electrification ...

On Equilibrium Figures of Particle Clouds around the Sun and Stars
Open Astronomy, 2015 Equilibrium figures of cold gas-dust (or cometary) clouds are studied in a more general setting than the classical Roche problem. The cloud is considered to be under the influence of gravitational attraction of the central star and the tidal field of the

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 5, September/October 2026.ABSTRACT This work examines magnetohydrodynamic (CeO2, Ti3C2/H2O) hybrid nanofluid (HNF) flow on an inclined revolving disk with effects of Newtonian heating. HNF is obtained by suspending the nanoparticles (NPs) of CeO2 and Ti3C2 in water (H2O). The flow is affected by mixed convection, Joule heating, nonlinear thermally radiative and dissipative ...

The Unreasonable Effectiveness of the nΣv Approximation
The Astrophysical JournalIn kinetic theory, the classic n Σ v approach calculates the rate of particle interactions from local quantities: the number density of particles n , the cross section Σ, and the average relative speed v .

Dynamical Structures Associated with High-Order and Secondary Resonances in the Spin–Orbit Problem
The Astronomical JournalIn our solar system, spin–orbit resonances are common under Sun–planet, planet–satellite, and binary asteroid configurations. In this work, high-order and secondary spin–orbit resonances are investigated by taking numerical and analytical approaches ...

A MODIFICATION OF GAUSS' METHOD FOR PRELIMINARY DETERMINATION OF A CELESTIAL BODY'S ORBIT
Odessa Astronomical Publications, 2016 A modification of classical Gauss’ method for determination of Keplerian elements from the observed positions is considered in this paper. The modification involves the exhaustive enumeration of all possible orbital plane positions in order to improve ...
