Collective dynamics of stock market efficiency
Luiz G. A. Alves, Higor Y. D. Sigaki, Matjaz Perc +1
Summarized by the efficient market hypothesis, the idea that stock prices fully reflect all available information is always confronted with the behavior of real-world markets. Whil…
Mapping images into ordinal networks
Arthur A. B. Pessa, Haroldo V. Ribeiro
An increasing abstraction has marked some recent investigations in network science. Examples include the development of algorithms that map time series data into networks whose ver…
City size and the spreading of COVID-19 in Brazil
Haroldo V. Ribeiro, Andre S. Sunahara, Jack Sutton +2
The current outbreak of the coronavirus disease 2019 (COVID-19) is an unprecedented example of how fast an infectious disease can spread around the globe (especially in urban areas…
Learning physical properties of liquid crystals with deep convolutional neural networks
Higor Y. D. Sigaki, Ervin K. Lenzi, Rafael S. Zola +2
Machine learning algorithms have been available since the 1990s, but it is much more recently that they have come into use also in the physical sciences. While these algorithms hav…
Quenched and Annealed Disorder Mechanisms in Comb-Models with Fractional Operators
A. A. Tateishi, H. V. Ribeiro, T. Sandev +2
Recent experimental findings on anomalous diffusion have demanded novel models that combine annealed (temporal) and quenched (spatial or static) disorder mechanisms. The comb-model…
