Specialization in food production affects global food security and food systems sustainability
(Elsevier, 2021-05)
Understanding specialization patterns of countries in food production can provide relevant insights for the evaluation and design of policies seeking to achieve food security and sustainability, which are key to reach ...
Digging the topology of rock art in northwestern Patagonia
(Oxford University Press, 2020-08)
We present a study on the rock art of northern Patagonia based on network analysis and communities detection. We unveil a significant aggregation of archaeological sites, linked by common rock art motifs that turn out to ...
Controllability of protein-protein interaction phosphorylation-based networks: Participation of the hub 14-3-3 protein family
(Nature Publishing Group, 2016-05)
Posttranslational regulation of protein function is an ubiquitous mechanism in eukaryotic cells. Here, we analyzed biological properties of nodes and edges of a human protein-protein interaction phosphorylation-based ...
Focused small-scale fisheries as complex systems using deep learning models
(Pontificia Universidad Católica de Valparaíso, 2021)
Robust timing and motor patterns by taming chaos in recurrent neural networks
(Nature Publishing Group, 2013-07)
The brain's ability to tell time and produce complex spatiotemporal motor patterns is critical for anticipating the next ring of a telephone or playing a musical instrument. One class of models proposes that these abilities ...
Modeling spatial patterns in the visual cortex
(American Physical Society, 2014-10)
We propose a model for the formation of patterns in the visual cortex. The dynamical units of the model are Kuramoto phase oscillators that interact through a complex network structure embedded in two dimensions. In this ...
The network organizational chart as a tool for managing organizational complexity
(WIT PressGB, 2016)
Companies in the twenty first century are required to continually adapt to an uncertain and ever-changing environment, which requires a more organic and flexible organization, without losing the benefits of volume production ...
Functional scale-free networks in the two-dimensional Abelian sandpile model
(American Physical Society, 2015-07)
Recently, the similarity of the functional network of the brain and the Ising model was investigated by Chialvo [Nat. Phys. 6, 744 (2010)]. This similarity supports the idea that the brain is a self-organized critical ...
Age density patterns in patients medical conditions: A clustering approach
(Public Library of Science, 2018-07)
This paper presents a data analysis framework to uncover relationships between health conditions, age and sex for a large population of patients. We study a massive heterogeneous sample of 1.7 million patients in Brazil, ...
