Quantifying the degree of average contraction of Collatz orbits
Timoteo Carletti, Duccio Fanelli
We here elaborate on a quantitative argument to support the validity of the Collatz conjecture, also known as the (3x + 1) or Syracuse conjecture. The analysis is structured as fol…
Highly inclined and eccentric massive planets. II. Planet-planet interactions during the disc phase
Sotiris Sotiriadis, Anne-Sophie Libert, Bertram Bitsch +1
We aim to investigate the influence of the eccentricity and inclination damping due to planet-disc interactions on the final configurations of the systems, generalizing previous st…
Geometric description of modular and weak values in discrete quantum systems using the Majorana representation
Mirko Cormann, Yves Caudano
We express modular and weak values of observables of three- and higher-level quantum systems in their polar form. The Majorana representation of N-level systems in terms of symmetr…
The role of homophily in the emergence of opinion controversies
F. Gargiulo, Y. Gandica
Understanding the emergence of strong controversial issues in modern societies is a key issue in opinion studies. A commonly diffused idea is the fact that the increasing of homoph…
Sub-GeV-scale signatures of hidden braneworlds up to the Planck scale in a -broken bulk
Coraline Stasser, Michael Sarrazin
Many-brane universes are at the heart of several cosmological scenarios related to physics beyond the Standard Model. It is then a major concern to constrain these approaches. Two-…
Interaction prediction between groundwater and quarry extension using discrete choice models and artificial neural networks
Johan Barthélemy, Timoteo Carletti, Louise Collier +3
Groundwater and rock are intensively exploited in the world. When a quarry is deepened the water table of the exploited geological formation might be reached. A dewatering system i…
