Force corporelle optimale pour le transfert de chaleur dans un tuyau chauffé vertical turbulent flux
Comme la flottabilité peut aider à générer un flux, the vertical heated-pipe arrangement is widely used in thermal engineering applications. Cependant, buoyancy suppresses and can even laminarise turbulence in the flow, thereby seriously damaging the heat transfer, mesuré par le nombre de Nusselt Nu. As...
Le processus d'annihilation du disque d'accrétion et des paires de neutrinos de Trou noir modifié par Barrow
This paper attempts to clarify the deep consequences of Barrow fractal black hole spacetime configurations caused by quantum gravity on neutrino pair annihilation and accretion disk dynamics. We systematically derive the analytical expression for the innermost stable circular orbit (ISCO) radius ($r_{\texte{ISCO}}\propto...
Leveraging differentiable programming in the inverse problem of neutron stars
Neutron stars (NSs) probe the high-density regime of the nuclear equation of state (EOS). Cependant, inferring the EOS from observations of NSs is a computationally challenging task. Dans ce travail, we efficiently solve this inverse problem by leveraging differential programming in two...
Sortie anticipée dynamique dans les modèles de raisonnement
Recent advances in large reasoning language models (LRLMs) rely on test-time scaling, which extends long chain-of-thought (CoT) generation to solve complex tasks. Cependant, overthinking in long CoT not only slows down the efficiency of problem solving, but also risks accuracy loss due...
SUPRA: Attention paramétrée sous-spatiale pour l'opérateur neuronal en général Domaines
Neural operators are efficient surrogate models for solving partial differential equations (PDE), mais leurs composants clés sont confrontés à des défis: (1) in order to improve accuracy, attention mechanisms suffer from computational inefficiency on large-scale meshes, et (2) spectral convolutions rely on the Fast Fourier...
RaSCL: Localisation radar à satellite
Le GNSS n'est pas fiable, inexacte, and insufficient in many real-time autonomous field applications. Dans ce travail, we present a GNSS-free global localization solution that contains a method of registering imaging radar on the ground with overhead RGB imagery, with joint optimization of relative...
Profils de densité des vides TNG300 à travers le temps cosmique
We present radial density profiles, as traced by luminous galaxies and dark matter particles, for voids in eleven snapshots of the \texttt{TNG300} simulation. The snapshots span 11.65~Gyr of cosmic time, corresponding to the redshift range $0 \le z \le 3$. Using the...
Augmentation dimensionnelle dans les théories conformes des champs
The n-point functions of any Conformal Field Theory (CFT) in $d$ dimensions can always be interpreted as spatial restrictions of corresponding functions in a higher-dimensional CFT with dimension $d’> d$. En particulier, when a four-point function in $d$ dimensions has a known...
GraphEdge: Partition de graphique dynamique et planification des tâches pour les GNN Informatique dans le réseau Edge
Avec la croissance exponentielle de l’Internet des objets (IdO) appareils, edge computing (CE) is gradually playing an important role in providing cost-effective services. Cependant, existing approaches struggle to perform well in graph-structured scenarios where user data is correlated, such as traffic flow...
Comportements répétitifs restreints chez les adolescents autistes: Volatilité des connectivités fonctionnelles cérébrales
This paper studies subtypes of restricted, repetitive and stereotypical behaviors (RRBs) in adolescent males with autism spectrum disorder (ASD) from the viewpoint of the dynamics of brain functional connectivities (FCs). Data from the ABIDE-II repository and Repetitive Behavior Scale-Revised (RBS-R) metrics are...
