Explaining the discrepancy in the Chandler period and the prediction of the changes in the Earths rotation dynamics
arXiv:2601.07738v1 Announce Type: new Abstract: In this paper, in the first instance the attitude dynamics of the Earth is modelled based on physical principles so as to correctly predict the Chandler wobble and its features such as its period. To this end not only the steady state and dynamic gravity gradient torques ...

Learning to bin: differentiable and Bayesian optimization for multi-dimensional discriminants in high-energy physics
arXiv:2601.07756v1 Announce Type: new Abstract: Categorizing events using discriminant observables is central to many high-energy physics analyses. Yet, bin boundaries are often chosen by hand. A simple, popular choice is to apply argmax projections of multi-class scores and equidistant binning of one-dimensional discr...
