The rise and fall of countries in the global value chains
Luiz G. A. Alves, Giuseppe Mangioni, Francisco A. Rodrigues +2
Countries participate in global value chains by engaging in backward and forward transactions connecting multiple geographically dispersed production stages. Inspired by network th…
Commuting network effect on urban wealth scaling
Luiz G. A. Alves, Diego Rybski, Haroldo V. Ribeiro
Urban scaling theory explains the increasing returns to scale of urban wealth indicators by the per capita increase of human interactions within cities. This explanation implicitly…
Spreader events and the limitations of projected networks for capturing dynamics on multipartite networks
Hyojun A. Lee, Luiz G. A. Alves, Luís A. Nunes Amaral
Many systems of scientific interest can be conceptualized as multipartite networks. Examples include the spread of sexually transmitted infections, scientific collaborations, human…
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…
Reconstructing commuters network using machine learning and urban indicators
Gabriel Spadon, Andre C. P. L. F. de Carvalho, Jose F. Rodrigues-Jr +1
Human mobility has a significant impact on several layers of society, from infrastructural planning and economics to the spread of diseases and crime. Representing the system as a…
Centrality anomalies in complex networks as a result of model over-simplification
Luiz G. A. Alves, Alberto Aleta, Francisco A. Rodrigues +2
Tremendous advances have been made in our understanding of the properties and evolution of complex networks. These advances were initially driven by information-poor empirical netw…
The hidden traits of endemic illiteracy in cities
Luiz G. A. Alves, Jose S. Andrade, Quentin S. Hanley +1
In spite of the considerable progress towards reducing illiteracy rates, many countries, including developed ones, have encountered difficulty achieving further reduction in these…
Unfolding the complexity of the global value chain: Strengths and entropy in the single-layer, multiplex, and multi-layer international trade networks
Luiz G. A. Alves, Giuseppe Mangioni, Francisco A. Rodrigues +2
The worldwide trade network has been widely studied through different data sets and network representations with a view to better understanding interactions among countries and pro…
The nested structural organization of the worldwide trade multi-layer network
Luiz G. A. Alves, Giuseppe Mangioni, Isabella Cingolani +3
Nestedness has traditionally been used to detect assembly patterns in meta-communities and networks of interacting species. Attempts have also been made to uncover nested structure…
The dynamical structure of political corruption networks
Haroldo V. Ribeiro, Luiz G. A. Alves, Alvaro F. Martins +2
Corruptive behaviour in politics limits economic growth, embezzles public funds, and promotes socio-economic inequality in modern democracies. We analyse well-documented political…
The role of city size and urban metrics on crime modeling
Luiz G. A. Alves, Haroldo V. Ribeiro, Francisco A. Rodrigues
Unveiling the relationships between crime and socioeconomic factors is crucial for modeling and preventing these illegal activities. Recently, a significant advance has been made i…
Crime prediction through urban metrics and statistical learning
Luiz G A Alves, Haroldo V Ribeiro, Francisco A Rodrigues
Understanding the causes of crime is a longstanding issue in researcher's agenda. While it is a hard task to extract causality from data, several linear models have been proposed t…
Long-range correlations and fractal dynamics in C. elegans: changes with aging and stress
Luiz G. A. Alves, Peter B. Winter, Leonardo N. Ferreira +3
Reduced motor control is one of the most frequent features associated with aging and disease. Nonlinear and fractal analyses have proved to be useful in investigating human physiol…
Transient superdiffusion and long-range correlations in the motility patterns of trypanosomatid flagellate protozoa
L. G. A. Alves, D. B. Scariot, R. R. Guimarães +3
We report on a diffusive analysis of the motion of flagellate protozoa species. These parasites are the etiological agents of neglected tropical diseases: leishmaniasis caused by L…
Scale-adjusted metrics for predicting the evolution of urban indicators and quantifying the performance of cities
Luiz G. A. Alves, Renio S. Mendes, Ervin K. Lenzi +1
More than a half of world population is now living in cities and this number is expected to be two-thirds by 2050. Fostered by the relevancy of a scientific characterization of cit…
Analogies between the cracking noise of ethanol-dampened charcoal and earthquakes
H. V. Ribeiro, L. S. Costa, L. G. A. Alves +4
We report on an extensive characterization of the cracking noise produced by charcoal samples when dampened with ethanol. We argue that the evaporation of ethanol causes transient…
Spatial correlations, clustering and percolation-like transitions in homicide crimes
L. G. A. Alves, E. K. Lenzi, R. S. Mendes +1
The spatial dynamics of criminal activities has been recently studied through statistical physics methods; however, models and results have been focused on local scales (city level…
Solutions for a q-generalized Schrödinger equation of entangled interacting particles
Luiz G. A. Alves, Haroldo V. Ribeiro, Maike A. F. Santos +2
We report on the time dependent solutions of the generalized Schrödinger equation proposed by Nobre et al. [Phys. Rev. Lett. 106, 140601 (2011)]. Here we investigate the case o…
Investigating the interplay between mechanisms of anomalous diffusion via fractional Brownian walks on a comb-like structure
H. V. Ribeiro, A. A. Tateishi, L. G. A. Alves +2
The comb model is a simplified description for anomalous diffusion under geometric constraints. It represents particles spreading out in a two-dimensional space where the motions i…
Empirical analysis on the connection between power-law distributions and allometries for urban indicators
Luiz G. A. Alves, Haroldo V. Ribeiro, Ervin K. Lenzi +1
We report on the existing connection between power-law distributions and allometries. As it was first reported in [PLoS ONE 7, e40393 (2012)] for the relationship between homicides…
