New arXiv preprint out with my postdoc Tibebe Birhanu @tibebe12.bsky.social on the time series analysis: Analysis framework for higher-order temporal correlations with applications to human heartbeats, arxiv.org/abs/2512.01235
Analysis framework for higher-order temporal correlations with applications to human heartbeats
We propose a time series analysis framework focused on higher-order temporal correlations in the event sequence beyond the interevent time distribution by employing the burst-tree decomposition method...

I submitted my manuscript to the arXiv one week ago, which is still "on hold", and didn't get any message from the arXiv since then. Should I wait longer or take any action?

Is this the first journal containing the term "social physics"? In any case, I'm excited to see that such journal has been finally started.
