New on the blog: A short post on reading in the age of AI. My rule: zero AI fiction. But I'm open to using LLMs to learn (yet uneasy that every prompt is a vote against Wikipedia and the open knowledge commons ... and many other issues). sunelehmann.com/blog/reading...

ArXiV has a new LLM policy (Screenshots with alt text so you don’t have to click through to the other place and see all the stupid responses)
Attention @arxiv authors: Our Code of Conduct states that by signing your name as an author of a paper, each author takes full responsibility for all its contents, irrespective of how the contents were generated. 1/If generative AI tools generate inappropriate language, plagiarized content, biased content, errors, mistakes, incorrect references, or misleading content, and that output is included in scientific works, it is the responsibility of the author(s). 2/

We have recently clarified our penalties for this. If a submission contains incontrovertible evidence that the authors did not check the results of LLM generation, this means we can't trust anything in the paper. 3/The penalty is a 1-year ban from arXiv followed by the requirement that subsequent arXiv submissions must first be accepted at a reputable peer-reviewed venue. 4/

Examples of incontrovertible evidence: hallucinated references, meta-comments from the LLM ("here is a 200 word summary; would you like me to make any changes?"; "the data in this table is illustrative, fill it in with the real numbers from your experiments") end/

One of the time-consuming tasks in paper writing is to curate bibtex for references. So I automated bibtex curation with an Alfred app that fetches entries from dx.doi.org using DOI or title. It saves time, reduces errors, and maintains consistent LaTeX keys. github.com/skojaku/tobi...

DTU scientists show that once you account for geographical restraints, there are consistent patterns behind human mobility.

There's much more awesomeness in the paper: We go deep on the pairwise distance distribution. And along the way, we model the distribution of houses in Denmark using old-school statistical physics and then connect everything through considering the inter/intra city mobility.
A large and unusually complex figure from the paper.

Sune Lehmann @sunelehmann.com · 04/09/2025
The 1/x power-law spans the scales of meters to hundreds of km. The way we unearth the power law is that in considering the raw mobility data (orange line), we account for the moves that are possible (blue line) encoded as the distribution of pairwise distances between locations.
Two distributions. One is orange and represents the distribution of empirical moves between houses in Denmark. The other is blue and represents the distribution of pairwise distances between houses in Denmark.

Super excited about our new paper on mobility that's out in Nature Human Behavior www.nature.com/articles/s41... I love this paper for many reasons, but one is that we find beautiful 1/x power-law that spans 6 orders of magnitude hidden within the "ugly" distribution raw mobility data.
A very straight line on a loglog plot. So straight that even Aaron Clauset would call this a power-law
