Our fall seminar series begins this Thursday, Oct. 2 (4pm UTC+1/11am EDT) with a talk by Elena Candellone. She’ll be speaking about “Mapping extreme users through negative ties in online social interactions”, followed by a discussion on “the joy of planning scientific events”.

Robustness of 'small' networks

Modeling how networks change under structural perturbations can yield foundational insights into network robustness, which is critical in many real-world applications. The largest connected component ...

Right, we solved directly for the stationary state, but one could also integrate for the transient. I'll look into it... thanks!

Oh, you have some nice calculations for the cluster expansion! But I think this reinfection counting has the same equilibrium prediction as the regular pair-approx

We found a nice way to accurately solve the SIS model. Rather than expanding in space with ever larger moment closures (pairs, triples, ...), we expand in time. No more difficult than pair-approximations yet much more accurate.

The threshold and quasi-stationary distribution for the SIS model on networks

We study the Susceptible-Infectious-Susceptible (SIS) model on arbitrary networks. The well-established pair approximation treats neighboring pairs of nodes exactly while making a mean field approxima...

‘Booty’ and ‘butt’ are synonyms.

‘Call’ and ‘dial’ are synonyms.

But, a ‘booty call’ and a ‘butt dial’ are VERY different things.

Not sure how many scientists here have tried Claude Code or similar command line coding assistants. I had a complicated family property tax problem that was best solved by a brute force Monte Carlo simulation approach, so I spent a few days coding up and analyzing a model with Claude Code.

The Kac formula says the average return time for a random walker is a wonderfully simple combination of global and local structure: 2m/k_i. Inspired by this result we characterize the full distribution in a similar manner. doi.org/10.1103/Phys...

Approximation for return time distributions of random walks on sparse networks
