DBGDGM: Dynamic Brain Graph Deep Generative Model [PDF]
arXiv, 2023 Graphs are a natural representation of brain activity derived from functional magnetic imaging (fMRI) data. It is well known that clusters of anatomical brain regions, known as functional connectivity networks (FCNs), encode temporal relationships which can serve as useful biomarkers for understanding brain function and dysfunction.

Instantaneous and limiting behavior of an n-node blockchain under cyber attacks from a single hacker [PDF]
arXiv, 2022 We investigate the instantaneous and limiting behavior of an n-node blockchain which is under continuous monitoring of the IT department of a company but faces non-stop cyber attacks from a single hacker. The blockchain is functional as far as no data stored on it has been changed, deleted, or locked.

Structural constraints on the emergence of oscillations in multi-population neural networks [PDF]
arXiv, 2023 Oscillations arise in many real-world systems and are associated with both functional and dysfunctional states. Whether a network can oscillate can be estimated if we know the strength of interaction between nodes. But in real-world networks (in particular in biological networks) it is usually not possible to know the exact connection weights ...
