Structure preserving discretization method for 1D and 2D port-Hamiltonian systems using finite differences on staggered grids
Ignacio Diaz Alastuey, Yann Le Gorrec, Yongxin Wu
This paper extends previous work on finitedifference schemes over staggered grids for infinite-dimensional port-Hamiltonian systems. In the one-dimensional setting, it generalizes…
Fancy Some Chips for Your TeaStore? Modeling the Control of an Adaptable Discrete System
Anna Gallone, Simon Bliudze, Sophie Cerf +1
When designing new web applications, developers must cope with different kinds of constraints relative to the resources they rely on: software, hardware, network, online micro-serv…
Thermodynamical study of N clathrate hydrate from DFT calculations
L. Martin-Gondre, V. Meko Fotso, C. Métais +3
Thermodynamic stability of N clathrate hydrates in the sI and sII structures is investigated using density functional theory with several exchange-correlation functionals, expl…
Search for a solar-bound axion halo using the Global Network of Optical Magnetometers for Exotic physics searches
Tatum Z. Wilson, Derek F. Jackson Kimball, Samer Afach +50
We report on a search for a gravitationally bound solar axion halo using data from the Global Network of Optical Magnetometers for Exotic physics searches (GNOME), a worldwide arra…
Identifying bound states in the continuum by their boundary sensitivity
Vincent Laude, David Röhlig
We introduce a method for effectively identifying bound states in the continuum (BICs) - notably without computing the imaginary part of the eigenvalues - thereby simplifying the m…
Metamaterials and Fluid Flows
Francesco Avallone, Federico Bosia, Yi Chen +20
Understanding and controlling the dynamic interactions between fluid flows and solid materials and structures-a field known as fluid-structure interaction -is central not only to e…
Moments of density-dependent branching processes and their genealogy
Mathilde André, Félix Foutel-Rodier, Emmanuel Schertzer
A density-dependent branching process is a particle system in which individuals reproduce independently, but in a way that depends on the current population size. This feature can…
Massey products and unipotent extensions with restricted ramification
Oussama Hamza, Donghyeok Lim, Christian Maire
We fix a prime p and construct new cases of pro-p extensions of number fields with restricted ramification and splitting, whose Galois groups decompose as coproducts of pro-p absol…
Ionic emissions and activity evolution in comet C/2020 F3 (NEOWISE): Insights from long-slit spectroscopy and photometry
K. Aravind, E. Jehin, S. Hmmidouch +7
Comet C/2020 F3 (NEOWISE) was the brightest comet in the northern hemisphere since C/1995 O1 (Hale-Bopp), providing a unique opportunity to study its composition and spatial distri…
NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)
Colin Orion Chandler, Pedro H. Bernardinelli, Mario Jurić +305
We report on the observation and measurement of astrometry, photometry, morphology, and activityof the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS) with the NSF-…
Euclid: The potential of slitless infrared spectroscopy: A z=5.4 quasar and new ultracool dwarfs
E. Bañados, V. Le Brun, S. Belladitta +226
We demonstrate the potential of Euclid's slitless spectroscopy to discover high-redshift (z>5) quasars and their main photometric contaminant, ultracool dwarfs. Sensitive infrared…
Distributional regression with reject option
Ahmed Zaoui, Clément Dombry
Selective prediction, where a model has the option to abstain from making a decision, is crucial for machine learning applications in which mistakes are costly. In this work, we fo…
Euclid: Quick Data Release (Q1) -- Ultracool dwarfs in the Euclid Deep Fields
A. Mohandasan, R. L. Smart, C. Reylé +180
Ultracool dwarfs (UCDs) encompass the lowest-mass stars and brown dwarfs at the substellar boundary. These intrinsically faint objects are challenging to detect, but the wide cover…
Exciton Binding Energies in 2D Materials: Insights from Braneworld Physics
Antoine Honet, Michaël Sarrazin
In the present work, we introduce a new interpretation of exciton binding energies in two-dimensional (2D) materials using concepts from brane physics. We adapt the Dvali-Gabadadze…
W-shaped Broadband Attenuation of Longitudinal Waves through Composite Elastic Metamaterial
B. Lemkalli, K. K. Dudek, M. Kadic +4
We investigate a composite elastic meta-slab with exceptional transmission properties, particularly the presence of a W-shaped bandgap. A comprehensive study, utilizing experimenta…
Euclid: Quick Data Release (Q1) -- A photometric search for ultracool dwarfs in the Euclid Deep Fields
M. Žerjal, C. Dominguez-Tagle, N. Vitas +178
We present a catalogue of 5306 new ultracool dwarf (UCD) candidates in the three Euclid Deep Fields in the Q1 data release. They range from late M to late T dwarfs, and include 120…
Limits of nonlinear and dispersive fiber propagation for an optical fiber-based extreme learning machine
Andrei V. Ermolaev, Mathilde Hary, Lev Leybov +5
We report a generalized nonlinear Schrödinger equation simulation model of an extreme learning machine (ELM) based on optical fiber propagation. Using the MNIST handwritten digit d…
