Nonlinear Diffusion and Decay of an Expanding Turbulent Blob
Turbulence, left unforced, decays and invades the surrounding quiescent fluid. Though ubiquitous, this simple phenomenon has proven hard to capture within a simple and general framework. Experiments in conventional turbulent flow chambers are inevitably complicated by proximity to boundaries and mean flow, obscuring the fundamental aspects of the relaxation to the quiescent fluid state. Here, we circumvent these issues by creating a spatially-localized blob of turbulent fluid using eight conver…

Aggregation of vortex structures in 2D: the blob-wave system and its role in zonal flows
We give a rigorous mathematical result, supported by accurate numerical simulations, of the aggregation of a concentrated vortex blob with an underlying non constant vorticity field: the blob moves in the direction of the gradient of the field. It is a unique example of Lagrangian explanation of aggregation of vortex structures of the same sign in 2D inviscid fluids. A conceptual model of zonal flow maintenance and modulation based on this idea is then developed, which produces shapes in accord…

I am familiar with the logistics, personally would print from local vendors.
Anyway, SVG here:

Da muss dann die Bibliothek, die den DNB-Lizenzierungsservice nutzt, kurioserweise hoffen, dass die digitalisierten Titel nicht allzu oft verwendet werden, denn das kostet dann extra 🙂

I made a helper for Proximity (a word association game like #Semantle). It lets you poke around the database to see what's close to what:

Last week, our students learned how to conduct a proper evaluation for an NLP experiment. To this end, we introduced a small textcorpus with sentences about Joseph Fourier, who counts as one of the discoverers of the greenhouse effect, responsible for global warming.

#PyYAML rejected #freethreading support. As a result, a new fork has been created with freethreading support. Given the fork's focus on freethreading, it supports only Python 3.13 . Given the lack of environment markers for freethreading (yet), packages end up depending on PyYAML-ft for >=3.13 (including non-freethreading builds), and PyYAML for <3.13.
Isn't #Python #packaging great?
