Schrödinger Equation with Geometric Constraints and Position-Dependent Mass
We investigate the solutions of the Schrödinger equation in the presence of geometric constraints represented by a backbone structure …
The Physics of Cities
The word “physics” can be understood in at least two ways. First, based on the Greek origin of the word, physics means …
Popularity of Video Games and Collective Memory
Describing the permanence of cultural objects is an important step in understanding societal trends. A relatively novel cultural object …
Clustering free-falling paper motion with complexity and entropy
Many simple natural phenomena are characterized by complex motion that appears random at first glance, but that often displays …
Universality of political corruption networks
Corruption crimes demand highly coordinated actions among criminal agents to succeed. But research dedicated to corruption networks is …
Permutation Jensen-Shannon distance: A versatile and fast symbolic tool for complex time-series analysis
The main motivation of this paper is to introduce the permutation Jensen-Shannon distance, a symbolic tool able to quantify the degree …
Fractional Diffusion with Geometric Constraints: Application to Signal Decay in Magnetic Resonance Imaging (MRI)
We investigate diffusion in three dimensions on a comb-like structure in which the particles move freely in a plane, but, out of this …

Lavanguardia: Críticos artificiales del arte humano
Los algoritmos llegan a las mismas interpretaciones y conclusiones sobre la pintura que los expertos más reputados.
Una investigación sobre arte basada en la inteligencia artificial demuestra que las métricas digitales fundamentadas en la física coinciden con los conceptos propuestos a lo largo de la historia por los expertos humanos.
Projects
Observatório COVID-19 Maringá
O site foi criado pelo Laboratório de Sistemas Complexos (Complex-Lab) da UEM para oferecer uma visualização da evolução dos casos de infecção por coronavírus na cidade de Maringá. Os dados utilizados em nossas análises são obtidos dos boletins diários divulgados pela Secretaria de Saúde de Maringá e dos sites: brasil.io, Dati COVID-19 Italia e Johns Hopkins CSSE.
