A fast and light stream cipher for smartphones
Gerard Vidal, Murilo Baptista, Hector Mancini
We present a stream cipher based on a chaotic dynamical system. Using a chaotic trajectory sampled under certain rules in order to avoid any attempt to reconstruct the original one…
A topological method to characterize tapped granular media from the position of the particles
Sergio Ardanza-Trevijano, Iker Zuriguel, Roberto Arevalo +1
We use the first Betti number of a complex to characterize the morphological structure of granular samples in mechanical equilibrium. We analyze two-dimensional granular packings a…
Simulation of counter flow pedestrian dynamics in hallways using spheropolygons
Fernando Alonso-Marroquin, Celia Lozano, Alvaro Ramirez-Gomez +1
We developed a method for simulating pedestrian dynamics in a large, dense crowd. Our numerical model calculates pedestrian motion from Newton second laws, taking into account visc…
Brittle to Ductile Transition in a Fiber Bundle with Strong Heterogeneity
K. Kovacs, R. C. Hidalgo, I. Pagonabarraga +1
We analyze the failure process of a two-component system with widely different fracture strength in the framework of a fiber bundle model with localized load sharing. A fraction 0\…
The Google Scholar Experiment: how to index false papers and manipulate bibliometric indicators
Emilio Delgado López-Cózar, Nicolás Robinson-Garcia, Daniel Torres-Salinas
Google Scholar has been well received by the research community. Its promises of free, universal and easy access to scientific literature as well as the perception that it covers b…
Letter to the editor: Against the Resilience of Rejected Manuscripts
Nicolas Robinson-Garcia, Daniel Torres-Salinas, J. M. Campanario +1
In this letter we propose the development of guidelines by the main editors associations as well as protocols within online journal management systems for keeping track of rejected…
