Frustrated bearings
R. S. Pires, A. A. Moreira, H. J. Herrmann +1
In a bearing state, touching spheres (disks in two dimensions) roll on each other without slip. Here we frustrate a system of touching spheres by imposing two different bearing sta…
Cracking urban mobility
H. A. Carmona, A. W. T. de Noronha, A. A. Moreira +2
Assessing the resilience of a road network is instrumental to improve existing infrastructures and design new ones. Here we apply the optimal path crack model (OPC) to investigate…
Circuits with broken fibration symmetries perform core logic computations in biological networks
Ian Leifer, Flaviano Morone, Saulo D. S. Reis +3
We show that logic computational circuits in gene regulatory networks arise from a fibration symmetry breaking in the network structure. From this idea we implement a constructive…
Flow through three-dimensional self-affine fractures
H. J. Seybold, H. A. Carmona, F. A. Leandro Filho +3
We investigate through numerical simulations of the Navier-Stokes equations the influence of the surface roughness on the fluid flow through fracture joints. Using the Hurst expone…
Spatio-temporal characteristics of dengue outbreaks
Saulo D. S. Reis, Lucas Böttcher, João P. da C. Nogueira +4
After their re-emergence in the last decades, dengue fever and other vector-borne diseases are a potential threat to the lives of millions of people. Based on a data set of dengue…
