Wie Robinhood mit unechten OpenAI- und SpaceX-Anteilen für Unruhe sorgt 
Robinhood bringt tokenisierte Anteile von SpaceX und OpenAI nach Europa – ohne Zustimmung der Firmen. Ist das Demokratisierung oder gefährliche Finanzalchemie?

A third of North American bird species are rapidly declining, study warns — Species Unite
Researchers tracked 495 species using citizen data and found nearly 75 percent are plummeting in the regions they once thrived.

Analysis on asymmetric metric measure spaces: $q$-heat flow, $q$-Laplacian and Sobolev spaces
We investigate geometric analysis on metric measure spaces equipped with asymmetric distance functions. Extending concepts from the symmetric case, we introduce upper gradients and corresponding $L^q$-energy functionals as well as $q$-Laplacian in the asymmetric setting. Along the lines of gradient flow theory, we then study $q$-heat flow as the $L^2$-gradient flow for $L^q$-energy. We also study the Sobolev spaces over asymmetric metric measure spaces, extending some results of Ambrosio--Gigli…

On low-dimensional approximation of function spaces of interior regularity
Many elliptic boundary value problems exhibit an interior regularity property, which can be exploited to construct local approximation spaces that converge exponentially within function spaces satisfying this property. These spaces can be used to define local ansatz spaces within the framework of generalised finite element methods, leading to a better relation between dimensionality and convergence order. In this paper, we present a new technique for the construction of such spaces for Lipschit…

Exploring a Graph-based Approach to Offline Reinforcement Learning for Sepsis Treatment
Sepsis is a serious, life-threatening condition. When treating sepsis, it is challenging to determine the correct amount of intravenous fluids and vasopressors for a given patient. While automated reinforcement learning (RL)-based methods have been used to support these decisions with promising results, previous studies have relied on relational data. Given the complexity of modern healthcare data, representing data as a graph may provide a more natural and effective approach. This study models…

That's a first for me. I own 3 cargo bikes; never broke a spoke before. Somehow my wife broke 5 on one of the #CargoBikes. She was apparently carrying a(n "overweight") coworker in it, so maybe that did it?
Though when I got the bike, it had a broken rear (enviolo) hub and multiple broke spokes. I probably reused the non-broken spokes (and I definitely reused the rim),…

fresh_webs: Freshwater stream webs
A set of 26 networks of trophic-level species interactions in streams in New Zealand, Maine and North Carolina. Networks include the identities of aquatic insect, algae and fish species and their trophic interactions. Excel and plain text adjacency matrices available; webs can be downloaded individually or as a group.
This network has 49 nodes and 110 edges.

foodweb_baywet: Florida cypress wetlands food web (1998)
Networks of carbon exchanges among species in the cypress wetlands of South Florida. One network covers the wet and the other the dry season. Each node represents a taxon (similar to a species), and a directed edge indicates that one taxon uses another as food.
This network has 128 nodes and 2106 edges.
