Regression Model for Speckled Data with Extremely Variability
A. D. C. Nascimento, J. M. Vasconcelos, R. J. Cintra +1
Synthetic aperture radar (SAR) is an efficient and widely used remote sensing tool. However, data extracted from SAR images are contaminated with speckle, which precludes the appli…
Quantum Multiplexer Simplification for State Preparation
José A. de Carvalho, Carlos A. Batista, Tiago M. L. de Veras +2
The initialization of quantum states or Quantum State Preparation (QSP) is a basic subroutine in quantum algorithms. In the worst case, general QSP algorithms are expensive due to…
Quantum Mechanics of Particles Constrained to Spiral Curves with Application to Polyene Chains
Eduardo V. S. Anjos, Antonio C. Pavão, Luiz C. B. da Silva +1
Context: Due to advances in synthesizing lower dimensional materials there is the challenge of finding the wave equation that effectively describes quantum particles moving on 1D a…
Dissecting Multifractal detrended cross-correlation analysis
Borko Stosic, Tatijana Stosic
In this work we address the question of the Multifractal detrended cross-correlation analysis method that has been subject to some controversies since its inception almost two deca…
Developers' Perceptions on the Impact of ChatGPT in Software Development: A Survey
Thiago S. Vaillant, Felipe Deveza de Almeida, Paulo Anselmo M. S. Neto +3
As Large Language Models (LLMs), including ChatGPT and analogous systems, continue to advance, their robust natural language processing capabilities and diverse applications have g…
Lévy flight for electrons in graphene in the presence of regions with enhanced spin-orbit coupling
Diego B. Fonseca, Anderson L. R. Barbosa, Luiz Felipe C. Pereira
We propose an electronic Lévy glass built from graphene nanoribbons in the presence of regions with enhanced spin-orbit coupling. Although electrons in graphene nanoribbons present…
