Historias de Gigantes nace como un lugar de inspiración dedicado a darle voz a los miles de heroes anónimos.

Entrevista corta a Johann H. Martínez realizada en Bélgica (2019) en aras de dar a conocer cómo, a pesar de muchas adversidades, el amor por lo que no hace, el perseguir sus propios sueños y la disciplina en el tiempo arrojan frutos. Link disponible acá

Disease outbreakes and Countries. Time series of agregated data of number infected subjects along time. Usually, in order to acount the non-statinary signals one can extract their log-returns as: $y_t+=log(x_t-1)-log(x_t)$. Here you can find the summary of the data: The type of disease, the country, the length of the time series (the number before time range), and the time range. Download it...

Flux Balance Analysis (FBA) had shown to be optimal to quantify the metabolic rate of cells and microorganisms. Its fundamentals are based on two key points: On one hand, metabolic processes can be depicted as two groups of entities that connect each other (Reactions and Associated metabolites); on the other hand, the dynamics in these connections came up from a series of coupled equations fe...

This year The NetSci conference will be held in Indiana. USA, after successful events in Zaragoza, Spain, and Seoul. Korea. As many of you will know, a popular and successful Brain Networks satellite ran in 2015 and 2016 at NetSci. This years' satellite is a natural evolution, promising to expand to envelope the full scope of the emerging field of Network Neuroscience, that's why we call it:
