Planification bidirectionnelle des tâches et des mouvements basée sur le renforcement hiérarchique Apprendre pour la confrontation stratégique
En robotique en essaim, scénarios de confrontation, including strategic confrontations, require efficient decision-making that integrates discrete commands and continuous actions. Traditional task and motion planning methods separate decision-making into two layers, but their unidirectional structure fails to capture the interdependence between these layers, limiting...
Défauts, Amortissement du son, et le pic Boson dans les solides amorphes
Two nearly universal and anomalous properties of glasses, the peak in the specific heat and plateau of the thermal conductivity, occur around the same temperature. This coincidence suggests that the two phenomena are related. Both effects can be rationalized by assuming Rayleigh...
Cryptoanalysis of a public key exchange based on circulant matrix over digital semiring
We present a cryptanalysis of a key exchange protocol based on the digital semiring. For this purpose, we find the maximal solution of a linear system over such semiring, and use the properties of circulant matrix to demonstrate that the protocol is...
Measurement of the time-integrated $CP$ asymmetry in $D^0 \to K^0_{\rm S} K^0_{\RM S}$ désintégrations en utilisant le marquage de saveur du côté opposé chez Belle et Belle II
We measure the time-integrated $CP$ asymmetry in $D^0 \to K^0_{\RM S} K^0_{\RM S}$ decays reconstructed in $e^+e^-\to c{\overline c}$ events collected by the Belle and Belle II experiments. The corresponding data samples have integrated luminosities of 980 et 428 fb${}^{-1}$, respectivement. À...
Algorithmes de branchement et de liaison en tant que schémas d'approximation en temps polynomial
Algorithmes de branchement et de liaison (B&B) et schémas d'approximation en temps polynomial (PTAS) sont deux domaines apparemment éloignés de l’optimisation combinatoire. We intend to (partiellement) bridge the gap between them while expanding the boundary of theoretical knowledge on the B&Cadre B. Branch-and-bound algorithms typically guarantee that an...
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...
