Our new preprint: Group polarization, influence, and domination in online interaction networks: A case study of the 2022 Brazilian elections
https://arxiv.org/abs/2303.16859

We show that in the whole network, the left-leaning high-influential information spreaders dominated, reaching a substantial fraction of users with fewer spreaders. However, when comparing domination inside the groups, the results are inverse. Right-leaning spreaders dominate their communities using few nodes, showing as the most capable of accomplishing coordinated communication.

I started working on a #julialang package to work with Random Dot Product Graphs (#RDPG). It's still in its infancy, as I'm moving a lot of my script code into it. Anybody keen to help out will find it here. https://github.com/gvdr/DotProductGraphs.jl

Qualcuno (che in 3 anni avrebbe potuto prendere una laurea in epidemiologia, ma preferisce chiedere i vostri soldi) continua a diffondere informazioni errate, questa volta sul caso Cina.

Vediamo perchè, rispolverando un pò di storia recente e adattandola ad oggi.

After 6 years using Gibbsian states for network density matrices, w/ @ArshamGhavasieh we've finally shown under which conditions they are also max-entropy network states!

We gain new insights on coalescence processes and find unexpected behaviors:

This is unexplored territory for us and our formalism. Collaborations are more than welcome.

What is the contribution of network asymmetries to the entropy?

To answer, we considered the case where such asymmetries are small enough to be considered as a perturbation of a symmetric structure.

We find the microscopic conditions to guarantee a physical entropy.

The paper has some bonus appendices, where we show some math to better understand statistical ensemble microstates in the case of Hermitian and non-Hermitian control operators, gaining interesting insights on entropy.

But here I want to mention another appendix.

We find that it is not trivial to tell in advance which class of network has the highest functional diversity: deducing it directly from the structure or the dynamical rules, alone, is impossible

Our density matrix formalism allows to consider the two factors, simultaneously

It has global maxima at different propagation scales for different networks with distinct dynamical coefficients, which is higher for the original network compared to the others in almost all cases considered.

Applications? See here the C. elegans neural network and its response to perturbations compared against two generative models from different ensembles.

We focused on the fragility of functional diversity: an
indicator of how a system can stay operative in noisy environments

Since we are less constrained, we can analyze what happens when coupling different network topologies with distinct (nonlinear) dynamics:

- build the corresponding partition functions
- calculate the entropy, ...
