Our new textbook ("Computational Statistical Physics") is available now (Amazon, orellfüssli, Thalia, CUP, ...). CUP grants a discount of 20% until Aug 31 (tinyurl.com/v2w6je8k). Official CUP description: tinyurl.com/54p7ryr9 @ETH_physics @CompMedUCLA @UvA_CSL @UvA_IAS

In collaboration with @LabSysMedUF, we developed artificial neural network (ANN) controllers designed for agent-based models (ABMs)—a widely used modeling framework in medical digital twins. Link to the full article: doi.org/10.1098/rsta.2…

HISTORY OF PHYSICS What's wrong with this Lagrangean? by David Mermin. [This is so funny that I'll post it in full]

In collaboration with @LabSysMedUF, we propose a method for controlling agent-based models using surrogate models: journals.plos.org/ploscompbiol/a… Our goal is to apply these techniques to the medical digital twin systems we are developing.

What is the future of biostatistics in AI era? What do you think? @StatModeling @Physical_Prep @drizopoulos @vadimZip @MaartenvSmeden @mark_vdlaan My opinion: digitalbiostatistics.com/2025/01/my-tho…

Because of clustering-induced interference effects, the quantum walk in the simulation below primarily alternates between two nodes. In contrast, a classical random walk on the same network would gradually diffuse across the entire network. More details: arxiv.org/abs/2412.04325

How to Infer Network Structure from Dynamics? Basic ideas: a) Find how time series information of a network dynamical system can be approximately represented by a linear system of equations that encodes network structure b) attempt to find the sparsest solution for the system (most links absent given the constraint equations) ➡️ exploit minimization of L1-norm: compressed sensing From my (quiet and non-buerocratic) times at @Cornell Thanks to @stevenstrogatz for advice, also for help in identifying valuable research questions journals.aps.org/prl/abstract/1…

I have an interesting Postdoc position to offer: I am looking for an interdisciplinary minded researcher to work together on computational social science for democracy. The position is for 3 years within a Horizon Europe Project. Please apply or share! …toruniversity.wd103.myworkdayjobs.com/en-US/Careers/…

Our minisymposium on "Complex Weights in Networks and Data Science" will take place on Tuesday, October 22nd, as part of #SIAMMDS24. meetings.siam.org/program.cfm?CO… Looking forward to discussions at the intersection of mathematical physics and data science.

In case you ever wondered where the "glass" in "spin glass" comes from. This is a great survey btw. "An informal introduction to the Parisi formula" arxiv.org/abs/2410.12364
