Tunneling in double-well potentials within Nelson's stochastic mechanics: Application to ammonia inversion
Danilo F. Schafaschek, Giovani L. Vasconcelos, Antônio M. S. Macêdo
Nelson's stochastic mechanics formulates quantum dynamics as a real-time conservative diffusion process in which a particle undergoes Brownian-like motion with a fluctuation amplit…
Correlation-Weighted Communicability Curvature as a Structural Driver of Dengue Spread: A Bayesian Spatial Analysis of Recife (2015-2024)
Marcílio Ferreira dos Santos, Cleiton de Lima Ricardo, Andreza dos Santos Rodrigues de Melo
We investigate whether the structural connectivity of urban road networks helps explain dengue incidence in Recife, Brazil (2015--2024). For each neighborhood, we compute the avera…
DermAI: Clinical dermatology acquisition through quality-driven image collection for AI classification in mobile
Thales Bezerra, Emanoel Thyago, Kelvin Cunha +9
AI-based dermatology adoption remains limited by biased datasets, variable image quality, and limited validation. We introduce DermAI, a lightweight, smartphone-based application t…
Energy Efficiency in Network Slicing: Survey and Taxonomy
Adnei Willian Donatti, Marcia Cristina Machado, Marvin Alexander Lopez Martinez +7
Network Slicing (NS) is a fundamental feature of 5G, 6G, and future mobile networks, enabling logically isolated virtual networks over shared infrastructure. As data demand increas…
Ergodic Hysteresis of the Kerr black hole spectrum
João Paulo Cavalcante, Maurício Richartz, Bruno Carneiro da Cunha
We uncover a cascade of exceptional points (EPs) in the quasinormal mode spectrum of massive scalar perturbations of Kerr black holes, revealing an intricate non-Hermitian structur…
Non-equilibrium phase transition and cultural drift in the continuous-trait Axelrod model
Paulo R. A. Campos, Sandro M. Reia, José F. Fontanari
The standard Axelrod model of cultural dissemination, based on discrete cultural traits, exhibits a non-equilibrium phase transition but is inherently limited by its inability to c…
Probing orbital currents through inverse orbital Hall and Rashba effects
E. Santos, J. L. Costa, R. L. Rodriguez-Suarez +2
We report a comprehensive experimental investigation of orbital-to-charge conversion in metallic and semiconductor materials, emphasizing the fundamental roles of the inverse orbit…
STRive: An association rule-based system for the exploration of spatiotemporal categorical data
Mauro Diaz, Luis Sante, Joel Perca +3
Effectively analyzing spatiotemporal data plays a central role in understanding real-world phenomena and informing decision-making. Capturing the interaction between spatial and te…
Emergent Self-propulsion of Skyrmionic Matter in Synthetic Antiferromagnets
Clecio C. de Souza Silva, Matheus V. Correia, Juan C. Pina Velasquez
Self-propulsion plays a crucial role in biological processes and nanorobotics, enabling small systems to move autonomously in noisy environments. Here, we theoretically demonstrate…
Detecção de Conflitos Semânticos com Testes Gerados por LLM
Nathalia Barbosa, Paulo Borba, Léuson Da Silva
Semantic conflicts arise when a developer introduces changes to a codebase that unintentionally affect the behavior of changes integrated in parallel by other developers. Tradition…
Boltzmann Thermometry at Cryogenic Temperatures Exploiting Stark Sublevels in Er/Yb-Codoped Yttrium Oxide Nanoparticles
Thomas Possmayer, Allison R. Pessoa, Jefferson A. O. Galindo +4
The development of reliable luminescent nanothermometers for cryogenic applications is essential for advancing quantum technologies, superconducting systems, and other fields that…
Realizing the Petz Recovery Map on an NMR Quantum Processor
Gayatri Singh, Ram Sagar Sahani, Vinayak Jagadish +3
The Petz recovery map is a central construct in quantum information theory, providing an explicit, channel-aware prescription for reversing the effects of noise. Unlike standard qu…
Spatial correlations in four-wave mixing with structured light
Mateus R. L. da Motta, Sandra S. Vianna
We present a detailed theoretical treatment of four-wave mixing (FWM) in a quantized paraxial framework, capturing the multi-spatial-mode nature of the biphoton state generated in…
