Complex Multilayer Networks Lab

Welcome @valedand.bsky.social to BlueSky!

If you are interested in biological complexity, computational neuroscience and population dynamics (eg epidemics) click on the follow button 🧠🦠!

🚨 Thrilled to release the official repository of the @comunelab.bsky.social!

It centralizes access to decade-long research outputs, including 57 data sets and 22 code libraries.

A titanic effort: 28,000 lines of code

We hope to accelerate #openScience in #ComplexSystems

Precision is not limited by the second law of thermodynamics - Nature Physics Clock precision is thought to be fundamentally limited by entropy production in out-of-equilibrium systems. A theoretical work now introduces a quantum clock design where precision grows exponentially...

Physical devices operating out of equilibrium are affected by thermal fluctuations, limiting their operational precision

Coherent quantum dynamics can surpass the traditional thermodynamic precision limits, guiding development of future high-precision quantum devices

It was a pleasure to lecture at the @netsciconf.bsky.social for an interested & interactive audience.

What's a model? Why do we model? Is our network a network? Can we restore broken and forgotten links?

I will post on #ComplexityThoughts about this lecture, which I have enjoyed to prepare.

I own a math proof for a slides to a young network scientist attending my lecture this morning.

I promised the proof at the end of the talk, but it was lunchtime and we missed the chance to discuss.

Can you help me to find/reach him? 🙏

Tomorrow, 10:35, FSE C1.005 at PHS1

The joint prob that you are in Maastricht and you still don't which satellite to attend is nearly zero.

But still, you can show up to our MIX-NEXT if you are curious about where the field is going and what we can do to make it happen.

Scales, structure, dynamics, information

Abiotic aldol reactions of formaldehyde with ketoses and aldoses—Implications for the prebiotic synthesis of sugars by the formose reaction The formose reaction is proposed to produce sugars of relevance to biomolecules (RNA). By 13C-NMR, the aldol reactions of formaldehyde are shown to proceed to form linear and finally branched ketoses....

"the concept of the formose reaction as a prebiotic source of ribose on early Earth needs serious reconsideration, and other models/options should be explored"

It's so reassuring that that little, pale, blue dot it's us, about 1 billion km away.

From ecology to epi, from resilience to climate change, the members of our lab will present several results at the next @netsciconf.bsky.social, while @manlius.bsky.social will give a lecture about the broken, lost and future links in #NetworkScience

Let's meet in Maastricht & let's get in touch!

The internet is one of the greatest achievements of humankind.

Yet, we didn't learn how to use it, especially since we give for granted that it has almost zero cost, like natural resources.

Well, indeed it does cost, a lot. And we should learn how to get the most at minimum collateral effects.

Do you know what's inside an ant nest?

It is possible to unravel its hidden organization into an intricate web of tunnels: a complex "city" emerges.

Glad to see that our recent paper on digital twins for biomedical systems aligns with this view: simple correlational data cannot be used for digital twins and, accordingly, for building decisions.

Nice write up on the consciousness IIT gwt debate. And huge fan of adversial collaboration. Although the problem here is that it was a collaboration between two overambitious theories. The right adversarial would have been convinced that such theories can not currently exist.

This highlights how a strong mutualistic interaction can promote the diversification of entire clades by influencing their phenotypes, defining their geographic distribution, and ultimately contributing to their evolutionary and ecological success 🧪🧬🐠

"we emphasize how a characterization of the unpredictability of a system gives a measure of its complexity. Adopting this point of view, we review some developments in the characterization of the predictability of systems showing different kinds of complexity"🧪

"It is shown that a dynamical system subject to both periodic forcing and random perturbation may show a resonance (peak in the power spectrum) which is absent when either the forcing or the perturbation is absent"

Preparing my next @netsciconf.bsky.social School lecture.

There are several #ComplexityThoughts I'll unpack across 2.5 hours (and many liquids).

💡 One spoiler: all unreliable networks are alike; each reliable network is reliable in its own way.

See you in Maastricht. #NetSky

Thrilled for the latest work from @comunelab.bsky.social !

We introduce a multilayer + multiscale model in two distinct frameworks (particle- & force-based), identifying how to balance contact and mobility cuts to mitigate epidemics. #ComplexSystems

Wherever we find orderly, stable systems in Nature, we find that they are hierarchically structured, for the simple reason that w/o such structuring of #ComplexSystems into sub-assemblies, there could be no order and stability-except the order of a dead universe filled with [..] gas.
