Test using Arrow for QGIS to geopandas conversion
In an attempt to speed-up (and make the conversion more robust, eg regarding datetime/timezone conversion and null values (https://codeberg.org/movingpandas/trajectools/issues/93)), we can try to use Arrow. Since QGIS currently does not support exporting a layer to Arrow, here is a test workaroun...

Comparison between the first Steklov eigenvalue and algebraic connectivity on trees
Trees can be regarded as discrete analogue of Hadamard manifolds, namely simply-connected Riemannian manifolds of non-positive sectional curvature. In this paper, we compare the first (non-trivial) Steklov eigenvalue and algebraic connectivity of trees with prescribed number of boundary vertices and matching number. It is particularly noteworthy that while the extremal trees coincide for both operators, their corresponding eigenvalues differ significantly.

Optimal CO2 storage management considering safety constraints in multi-stakeholder multi-site CCS projects: a game theoretic perspective
Carbon capture and storage (CCS) projects typically involve a diverse array of stakeholders or players from public, private, and regulatory sectors, each with different objectives and responsibilities. Given the complexity, scale, and long-term nature of CCS operations, determining whether individual stakeholders can independently maximize their interests or whether collaborative coalition agreements are needed remains a central question for effective CCS project planning and management. CCS pr…

Niklas Orrenius: Varför går nazistiskt våld under radarn?
Medlemmar i nazistgruppen White Boys utreds för flera våldsamma attacker på Stockholms gator. Enligt åklagaren finns misstankar om hatbrottsmotiv.

Holy cow. Finnish prosecutors have charged a second person, a 28-year-old foreign national, in the hacking of the Vastaamo psychotherapy center.
