A. C. Braga, L. G. A. Alves, L. S. Costa, A. A. Ribeiro, M. M. A. de Jesus, A. A. Tateishi e H. V. Ribeiro

Physica A: Statistical Mechanics and its Applications – Volume: 444; Pages: 1003–1011; DOI: 10.1016/j.physa.2015.10.102; 2016

We report on a large-scale characterization of river discharges by employing the network framework of the horizontal […]

San Giorgio Prize for Prof. Luiz Roberto Evangelista

Prof. Luiz Roberto Evangelista awarded the prize San Giorgio per Distinzione Accademica, Centro Studi Molisano, Campobasso (Italy). Prof. Evangelista is a physicist and a distinguished academic of international reputation. He was born in Maringa, Parana, Brazil, on March 2, 1958. His great-grandparents were from Molise and arrived in Brazil in the late nineteenth century (1897).

Rural to Urban Population Density Scaling of Crime and Property Transactions in English and Welsh Parliamentary Constituencies

Quentin S. Hanley, Dan Lewis e Haroldo V. Ribeiro

PLOS ONE – Volume: 11; Issue: 2; Number article: e0149546; DOI: 10.1371/journal.pone.0149546; 2016

Urban population scaling of resource use, creativity metrics, and human behaviors has been widely studied. These studies have not looked in detail at the full range of human environments which represent a continuum from the most […]

Analogies Between the Cracking Noise of Ethanol-Dampened Charcoal and Earthquakes

Haroldo V. Ribeiro, Leandro S. Costa, Luiz G. Andrade Alves, Perseu A. Santoro, Sergio de Picoli Jr., Ervin K. Lenzi e Renio S. Mendes

Physical Review Letters – Volume: 115; Issue: 2; Article Number: 025503; DOI: 10.1103/PhysRevLett.115.025503; 2015

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 […]

Unusual diffusing regimes caused by different adsorbing surfaces

Veridiana G. Guimarães, Haroldo V. Ribeiro, Quan Li, Luiz R. Evangelista, Ervin K. Lenzi e Rafael S. Zola

Soft Matter – Volume: 11; Issue: 9; Pages: 1658-1666; DOI: 10.1039/C5SM00151J; 2015

A confined liquid with dispersed neutral particles is theoretically studied when the limiting surfaces present different dynamics for the adsorption–desorption phenomena. The investigation considers different non-singular kernels in […]

Light-Directing Omnidirectional Circularly Polarized Reflection from Liquid-Crystal Droplets

Jing Fan, Yannian Li, Hari Krishna Bisoyi, Rafael S. Zola, Deng-ke Yang, Timothy J. Bunning, David A. Weitz e Quan Li

Angewandte Chemie International Edition – Volume: 54; Issue: 7; Pages: 2160–2164; 2015

Constructing and tuning self-organized three-dimensional (3D) superstructures with tailored functionality is crucial in the nanofabrication of smart molecular devices. Herein we fabricate a self-organized, […]

Unravelling the effects of radiation forces in water

Nelson G. C. Astrath, Luis C. Malacarne, Mauro L. Baesso, Gustavo V. B. Lukasievicz e Stephen E. Bialkowski

Nature Communications – Volume: 5; Article number: 4363; DOI:10.1038/ncomms5363; 2014

The effect of radiation forces at the interface between dielectric materials has been a long-standing debate for over a century. Yet there has been so far only limited experimental verification […]

Distance to the Scaling Law: A Useful Approach for Unveiling Relationships between Crime and Urban Metrics

Luiz G. de Andrade Alves, Haroldo V. Ribeiro , Ervin K. Lenzi e Renio dos S. Mendes

PLOS ONE – Volume: 8; Issue: 8; Article Number: e69580; DOI: 10.1371/journal.pone.0069580; 2013

We report on a quantitative analysis of relationships between the number of homicides, population size and ten other urban metrics. By using data from Brazilian cities, we […]

Surface Induced Phase Separation and Pattern Formation at the Isotropic Interface in Chiral Nematic Liquid Crystals

Rafael S. Zola, Luiz R. Evangelista, Y.-C Yang e D.-K. Yang

Physical Review Letters – Volume: 110; Issue: 5; Article Number: 057801; DOI: 10.1103/PhysRevLett.110.057801; 2013

We study the pattern formation of a chiral nematic liquid crystal under a wetting transition. In the isotropic-liquid crystal transition, a surface-enhanced effect happens and a thin liquid crystal layer forms at […]
