Symbolic Higher-Order Analysis of Multivariate Time Series
Identifying patterns of relations among the units of a complex system from measurements of their activities in time is a fundamental problem with many practical applications. Here, we introduce a method that detects dependencies of any order in multivariate time series data. The method first transforms a multivariate time series into a symbolic sequence, and then extract statistically significant strings of symbols through a Bayesian approach. Such motifs are finally modelled as the hyperedges …

One of the goals I've set for further development of #Python eclasses in #Gentoo was to avoid needless complexity. Unfortunately, the subject matter sometimes requires them. However, many of the functions added lately were already manually done in ebuilds for years.
We've started disabling plugin autoloading years ago. First we just did that for individual packages that caused issues. Then, for these where tests ended up being really slow. Finally, pretty much anywhere `python_test()` was declared. Doing it all manually was particularly cumbersome — all I needed for `EPYTEST_PLUGINS` is a good idea how to generalize it.
Similarly, `EPYTEST_XDIST` was added after we have been adding manually `epytest -p xdist -n "$(makeopts_jobs)" --dist=worksteal` — and while at it, I've added `EPYTEST_JOBS` to override the job count.
Perhaps `EPYTEST_TIMEOUT` wasn't that common. However, it was meant to help CI systems that could otherwise get stuck on hanging test.
Similarly, "standard library" version (like `3.9`) matching to `python_gen_cond_dep` was added after a long period of explicitly stating `python3_9 pypy3`. As an extra benefit, this also resolved the problem that at the time `pypy3` could mean different Python versions.

Effects of higher-order interactions and homophily on information access inequality
The spread of information through socio-technical systems determines which individuals are the first to gain access to opportunities and insights. Yet, the pathways through which information flows can be skewed, leading to systematic differences in access across social groups. These inequalities remain poorly characterized in settings involving nonlinear social contagion and higher-order interactions that exhibit homophily. We introduce a enerative model for hypergraphs with hyperedge homophily…

Sometimes {renv} just isnt enough to ensure your environment is controlled. Maybe {slushy} could be an option? https://gsk-biostatistics.github.io/slushy/index.html

So I've just bumped a bunch of old #Gentoo packages to EAPI 8. Some of them haven't been updated for 6 years. And do you know what's best? They still worked — their build systems work, they compile and they just work. Unlike most of the stuff developed these days.

Internal collisions with nuclei detected *during* electron quantum tunneling:
"electrons do not simply pass through the barrier but collide again with the atomic nucleus inside the tunnel. The research team named this process ‘under-the-barrier recollision’ (UBR). Until now, it was believed that electrons could only interact with the nucleus after exiting the tunnel, but this study confirmed for the first time that such interaction can occur inside the tunnel.
"Even more…

Century-Old Quantum Mystery Solved: Scientists Finally See Inside the Electron’s “Tunnel”
A team of physicists has experimentally uncovered what electrons do during quantum tunneling, revealing a surprising internal collision process that challenges long-held beliefs. Professor Dong Eon Kim of POSTECH’s Department of Physics, in collaboration with the Max Planck Korea-POSTECH Initiati

Transport Network, Graph, and Air Pollution
Air pollution can be studied in the urban structure regulated by transport networks. Transport networks can be studied as geometric and topological graph characteristics through designed models. Current studies do not offer a comprehensive view as limited models with insufficient features are examined. Our study finds geometric patterns of pollution-indicated transport networks through 0.3 million image interpretations of global cities. These are then described as part of 12 indices to investig…

Okay, time to continue bashing. Perhaps this one project is just that bad, but Conan sounds like a complete antithesis of what a package manager is all about.
Well, this package insists to build its dependencies via Conan. Except it insists on really old versions that don't work with my glibc. So I need to start swapping dependencies.
Except it turns out Conan doesn't care much about resolving dependencies. So I actually need to start adjust versions of the dependencies of packages that it wants to build. And then it starts rebuilding other stuff and again everything fails because of incompatible versions.
And when I finally manage to find a working set, the actual project fails over protobuf version. After a long WTF-ing, I finally realize that it's complaining, because it somehow managed to mix the version of protobuf built by Conan and the external protobuf installed by Conda.
So yeah, great job. A package manager that doesn't really resolve dependencies but instead forces a dependency hell on you, and on top of that ends up mixing system packages with its own packages.

Harder, shorter, sharper, forward: A comparison of women's and men's elite football gameplay (2020-2025)
Elite football is believed to have evolved in recent years, but systematic evidence for the pace and form of that change is sparse. Drawing on event-level records for 13,067 matches in ten top-tier men's and women's leagues in England, Spain, Germany, Italy, and the United States (2020-2025), we quantify match dynamics with two views: conventional performance statistics and pitch-passing networks that track ball movement among a grid of pitch (field) regions. Between 2020 and 2025, average pass…

Incorporating episodic memory into quantum models of judgment and decision
An important challenge for quantum theories of cognition and decision concerns the incorporation of memory for recently made judgments and their effects on later judgments. First, we review a general approach to measurement based on system plus environment representations of states and measurement instruments. These more general measurement models provide ways to incorporate effects of recent judgments on later judgments. Then we compare three different measurement models that are based on thes…
