MHD Simulations Preliminarily Predict The Habitability and Radio Emission of TRAPPIST-1e
As the closest Earth-like exoplanet within the habitable zone of the M-dwarf star TRAPPIST-1, TRAPPIST-1e exhibits a magnetic field topology that is dependent on space weather conditions. Variations in these conditions influence its habitability and contribute to its radio emissions. Our objective...
Backslash: Rate Constrained Optimized Training of Large Language Models
The rapid advancement of large-language models (LLM) has driven extensive research into parameter compression after training has been completed, yet compression during the training phase remains largely unexplored. Dans ce travail, we introduce Rate-Constrained Training (Backslash), a novel training-time compression approach based...
Quantum walk search for exceptional configurations on one- and two-dimensional lattice with extra long-range edges of HN4 network
There exist several types of configurations of marked vertices, referred to as the exceptional configurations, on one- and two-dimensional periodic lattices with additional long-range edges of the HN4 network, which are challenging to find using discrete-time quantum walk algorithms. In this article,...
Anomalies in Muon-Induced Neutron Emissions from Pb
This paper analyses neutron multiplicity spectra from massive targets at depths of 3, 40, 210, 583, 1166, et 4000 m.w.e. The measurements, conducted between 2001 et 2024, utilised three experimental setups with either 14 ou 60 He-3 neutron detectors and lead (Pb)...
Representation Learning via Non-Contrastive Mutual Information
Labeling data is often very time consuming and expensive, leaving us with a majority of unlabeled data. Self-supervised representation learning methods such as SimCLR (Chen et al., 2020) or BYOL (Grill et al., 2020) have been very successful at learning meaningful latent...
Efficient Data Valuation Approximation in Federated Learning: A Sampling-based Approach
Federated learning paradigm to utilize datasets across multiple data providers. In FL, cross-silo data providers often hesitate to share their high-quality dataset unless their data value can be fairly assessed. Shapley value (SV) has been advocated as the standard metric for data...
Emergent topological phases and coexistence of gapless and spectral-localized Floquet quantum spin Hall states via electron-phonon interaction
Dans ce travail, a thorough exploration has been carried out to unravel the role of electron-phonon interaction (EPI) in a Bernevig-Hughes-Zhang (BHZ) quantum spin Hall (QSH) insulator subjected to a time-periodic step drive. It is observed that upon inclusion of the EPI,...
An Intersection Product for the Polytope Algebra
We introduce a new multiplication for the polytope algebra, defined via the intersection of polytopes. After establishing the foundational properties of this intersection product, we investigate finite-dimensional subalgebras that arise naturally from this construction. These subalgebras can be regarded as volumetric analogues...
Transition mechanisms in hypersonic wind-tunnel nozzles: a methodological approach using global linear stability analysis
Base-flow computations and stability analyses are performed for a hypersonic wind tunnel nozzle at a Mach number of 6. Isothermal and adiabatic wall boundary conditions are investigated, and moderate stagnation conditions are used to provide representative scenarios to study the transition in...
Outer regions of galaxy clusters as a new probe to test modifications to gravity
We apply the caustic technique to samples of galaxy clusters stacked in redshift space to estimate the gravitational potential in the cluster’s outer region and test modifications to the standard theory of gravity. We separate 122 galaxy clusters from the HeCS-SZ, HeCS-redMapper,...
