The CompGIT package: a computational tool for Geometric Invariant Theory quotie
We describe CompGIT, a SageMath package to describe Geometric Invariant Theory (GIT) quotients of projective space by simple groups. The implementation is based on algorithms described by Gallardo--Martinez-Garcia--Moon--Swinarski. In principle the package is sufficient to describe any GIT quotient of a projective variety by a simple group -- in practice it requires that the user can construct an equivariant embedding of the polarised variety into projective space. The package describes the non…

LLM-Based Bot Broadens the Range of Arguments in Online Discussions, Even When Transparently Disclosed as AI
A wide range of participation is essential for democracy, as it helps prevent the dominance of extreme views, erosion of legitimacy, and political polarization. However, engagement in online political discussions often features a limited spectrum of views due to high levels of self-selection and the tendency of online platforms to facilitate exchanges primarily among like-minded individuals. This study examines whether an LLM-based bot can widen the scope of perspectives expressed by participan…

Data marketplaces can increase the willingness to share social media data at low prices
Living in the Post API age, researchers face unprecedented challenges in obtaining social media data, while users are concerned about how big tech companies use their data. Data donation offers a promising alternative, however, its scalability is limited by low participation and high dropout rates. Research suggests that data marketplaces could be a solution, but its realization remains challenging due to theoretical gaps in treating data as an asset. This paper examines whether data marketplac…

Radiochromic Film Dosimetry for VHEE and UHDR: Considerations for the CLEAR Facility and Comparisons with Alanine, RPL and Dosimetry Phantoms
Radiochromic films (RCFs) offer valuable two-dimensional dosimetry capabilities with a conceptually simple operating principle that requires minimal investment, making them particularly suitable for very high energy electron (VHEE) FLASH dosimetry where dosimetry standards are currently lacking. However, achieving high-accuracy measurements with RCFs presents significant practical challenges. Without the standardised protocols that ensure reliable outcomes across applications and facilities, kn…

Even een reactie van mij uit een draadje bevrijdt ...
In de hele discussie over politici door de jaren heen heb ik bij figuren als Wilders dat onderstaande voorbeeld gebruikt. Echte argumenten zijn meestal niet aan de orde aangezien die discussies vaak platgeslagen worden met gelul wat wel leuk overkomt, maar geen basis heeft.
In dit geval is t met Wilders overduidelijk: hij kan niet leveren. Ook al heeft zn partij ministeries im handen en 3 bondgenoten.

Contribution of expert aggregation to temperature prediction part I
Many Numerical Weather Prediction (NWP) models and their associated Model Output Statistics (MOS) are available. Combining all of these predictions in an optimal way is however not straightforward. This can be achieved thanks to Expert Aggregation (EA) [Cesa-Bianchi and Lugosi, 2006, Gaillard et al., 2014, Wintenberger, 2024] which has many advantages, such as being online, being adaptive to model changes and having theoretical guarantees. Hence, in this paper, we propose a method for making de…
