Robotic-supported Data Loss Detection in Android Applications
Davi Freitas, Breno Miranda, Juliano Iyoda
Smartphones have become integral to modern life due to their diverse applications. However, the development of applications for these devices faces significant challenges, primaril…
An Empirical Analysis of Cross-OS Portability Issues in Python Projects
Denini Silva, MohamadAli Farahat, Marcelo d'Amorim
While Python is designed as a cross-platform language, real-world applications encounter portability failures when deployed across different operating systems. We present the first…
Observation of Replica Symmetry Breaking in Filamentation and Multifilamentation
André C. A. Siqueira, Guillermo Palacios, Jessica E. Q. Bautista +4
We report the experimental observation and characterization of Replica Symmetry Breaking (RSB) manifestation while analyzing the transverse intensity profile of pulses in filamenta…
Replica Symmetry Breaking in the Quasi Mode Locked Regime of Titanium Sapphire Lasers
Nicolas P. Alves, Ricardo V. M. de Almeida Filho, Isaac C. Nunes +4
Recent observations of replica symmetry breaking (RSB) in ytterbium-based mode-locked fiber lasers have revealed glassy behavior in the quasi-mode-locked (QML) regime. Here, we inv…
Perfect numbers, Wieferich primes and the solutions of
Gabriel Guedes, Ricardo Machado
In this article we focus on the solutions of a congruence equation: . Using the main result of this article and the SageMath software, we improve l…
An O-RAN-Assisted MARL Approach for Dynamic Sidelink and Infrastructure Selection in V2X Communications
Maria Katarine Santana Barbosa, Kelvin Lopes Dias
Future applications in the 6G-based Internet of Vehicles will leverage sidelink (SL) transmissions in Vehicle-to-Everything (V2X) scenarios. However, SL-based direct communication…
Numerical simulations and universal saturation profiles for viscous fingering patterns in Hele-Shaw flow
Irio M. Coutinho, Liam C. Morrow, Scott W. McCue
Hele-Shaw flows with an interface are known to give rise to complex pattern formation, whereby the Saffman-Taylor instability triggers a viscous fingering process accompanied by ti…
Trimers in the Extended Hubbard Model
R. R. Montenegro-Filho, D. R. B. Silva, D. Cogollo +1
The Lieb theorem is a cornerstone of quantum magnetism theory in condensed matter. In this work, we investigate the instability of the Lieb insulating ferrimagnetic phase in the ex…
Mixed-spin Heisenberg ladders in a magnetic field
D. S. Almeida, A. S. Bibiano, W. M. da Silva +1
In this work, we study alternating mixed-spin Heisenberg ladders in the magnetic field using density matrix renormalization group and linear spin-wave calculations. The…
Co-Construction Blindness and Asymmetric Epistemic Vulnerability in Human-LLM Interaction
Bianca Helena Ximenes
This paper introduces two constructs to describe, as far as we know, a previously unnamed risk in human-LLM interaction. Co-construction blindness is the failure to recognize that…
AgentxGCore: Agentic AI for Next-Generation Mobile Core Network
Maria Katarine Santana Barbosa, Kelvin L. Dias
To meet the stringent requirements of emerging applications and the increasingly complex network management and operation, the Next Generation Mobile Networks (NextG), or 6G, will…
Investigating spin and orbital effects via spin-torque ferromagnetic resonance
J. L. Costa, E. Santos, A. Y. M. Tani +2
In this work, we experimentally investigate spin and orbital torque phenomena using the spin-torque ferromagnetic resonance (ST-FMR) technique in a series of bilayer systems compos…
Dissipative realization of a quantum distance-based classifier using open quantum walks
Pedro Linck, Graeme Pleasance, Francesco Petruccione +1
Open quantum walks (OQWs) constitute a class of quantum walks whose dynamics are entirely driven by interactions with the environment. It is well known that OQWs provide a general…
Optimized Phase Masks for Absorption of Ultra-Broadband Pulses by Narrowband Atomic Ensembles
L. B. A. Mélo, Daniel Felinto, Marcio H. G. de Miranda
By combining genetic algorithm and a spatial light modulator we theoretically analyse how to improve a two-photon cascade absorption in atomic ensembles, inspecting the impact of v…
Multiplierless DFT Approximation Based on the Prime Factor Algorithm
L. Portella, F. M. Bayer, R. J. Cintra
Matrix approximation methods have successfully produced efficient, low-complexity approximate transforms for the discrete cosine transforms and the discrete Fourier transforms. For…
Hybrid-Field Channel Estimation for XL-MIMO Systems: Dictionary-based Sparse Signal Recovery
David William Marques Guerra, Taufik Abrao
Extremely large-scale multiple-input multiple-output (XL-MIMO) systems are a key technology for future wireless networks, but the large array aperture naturally creates a hybrid-fi…
Contrastive meta-domain adaptation for robust skin lesion classification across clinical and acquisition conditions
Rodrigo Mota, Kelvin Cunha, Emanoel dos Santos +6
Deep learning models for dermatological image analysis remain sensitive to acquisition variability and domain-specific visual characteristics, leading to performance degradation wh…
DerMAE: Improving skin lesion classification through conditioned latent diffusion and MAE distillation
Francisco Filho, Kelvin Cunha, Fábio Papais +6
Skin lesion classification datasets often suffer from severe class imbalance, with malignant cases significantly underrepresented, leading to biased decision boundaries during deep…
Emergent togetherness in collaborative dance improvisation: neural and motor synchronization reveal a coupling-decoupling paradox
Yago Emanoel Ramos, Raphael Silva do Rosário, Adriana de Faria Gehres +6
Collective improvisation in dance provides a rich natural laboratory for studying emergent coordination in coupled neuro-motor systems. Here, we investigate how training shapes spo…
Lévy walkers inside spherical shells with absorbing boundaries: Towards settling the optimal Lévy walk strategy for random searches
L. G. P. Caramês, Y. B. Matos, F. Bartumeus +5
The Lévy flight foraging hypothesis states that organisms must have evolved adaptations to exploit Lévy walk search strategies. Indeed, it is widely accepted that inverse square Lé…
