Synergistic Motifs in Gaussian Systems High-order interdependencies are central features of complex systems, yet a mechanistic explanation for their emergence remains elusive. Currently, it is unknown under what conditions high-order inter...

🚨 How do collective behaviours (high-order interdependencies) *emerge*❓

Can systems with low-order interactions do it?
What do these minimal synergistic systems look like?

In arxiv.org/abs/2505.246... we show when and how synergies emerge when no high-order mechanisms are involved.

Here there is clearly a misalignment with the terminology used by neuroscientists where what you call structural would be functional and what you call functional would be effective. These discrepancies do not help for sure.

I think of functional connectivity as per the definition of Friston who clearly describes three types connectivities: structural, functional (statistical dependencies) and effective connectivity (possibly causal). In this respect I think there is no confusion.

Interested in using (possibly physics-based) ML to characterise wave dynamics in atrial fibrillation? Get in touch!

I missed this post. Could you please add me? Many thanks!

Try cse from sympy (common subsequence elimination) or talk to your FOSS colleagues for something smarter :)

Around 300 jobs set to go in ‘very difficult’ Sussex redundancies Vice-chancellor says university has ‘done everything’ it can to reduce costs before cutting jobs

The THE (www.timeshighereducation.com/news/around-...) suggests Sussex is the 80th university known to announce cuts... It is sector wide!

This is the bit that really confuses me about this dichotomy between oscillatory and aperiodic. Are we saying that at a given frequency only a fraction of that power is down to ‘oscillations’ and the rest is aperiodic but with power at that frequency?

Great topic. I’d like to be added please.
