ARD-Korrespondentin Willinger: Türkei hat sich als Vermittler bewiesen
Die Türkei habe in den vergangenen Wochen gezeigt, dass sie für die Rolle des Vermittlers zwischen Moskau und Kiew geeignet sei, sagte ARD-Korrespondentin Katharina Willinger in Istanbul. Präsident Erdogan und seine Regierung pflegten gute Kontakte - sowohl zur Ukraine als auch zu Russland. Im Gegensatz zu den USA erkenne die Tür…

The proposed transit sales tax is “‘problematic for two reasons; one, it does not fully fund the operational shortfall. It’s also a politically vulnerable ballot measure,’ said Ryan Williams, the campaign director for Bay Area Forward, founded this year by local transit unions.”

Diffusion Tensor MRI and Spherical-Deconvolution-Based Tractography on an Ultra-Low Field Portable MRI System
Ultra-low-field (ULF) MRI is emerging as an alternative modality to high-field (HF) MRI due to its lower cost, minimal siting requirements, portability, and enhanced accessibility factors that enable large-scale deployment. Although ULF-MRI exhibits lower signal-to-noise ratio (SNR), advanced imaging and data-driven denoising methods enabled by high-performance computing have made contrasts like diffusion-weighted imaging (DWI) feasible at ULF. This study investigates the potential and limitati…

Functoriality of the Klein-Williams Invariant and Universality Theory
Both the Klein-Williams invariant $\ell_G(f)$ from \cite{KW2} and the generalized equivariant Lefschetz invariant $λ_G(f)$ from \cite{weber07} serve as complete obstructions to the fixed point problem in the equivariant setting. The latter is functorial in the sense of Definition \ref{functorial}. The first part of this paper aims to demonstrate that $\ell_G(f)$ is also functorial. The second part summarizes the ``universality" theory of such functorial invariants, developed in \cites{lueck199…

On different platforms, I see at least one post per day of someone willing to switch to #Linux. While seeing our community growing is nice, my first reaction is always: why didn't you take 3 seconds to read the post just before yours?
I may just become too old and grumpy but, generally speaking, I don't understand people who immediatly ask a question that has been answered thous…

The cat here is the most friendly, playful cat I have ever experienced. It also came in expecting to play at 5am (I couldn’t sleep anyway.) Needless to say, “no” wasn’t a concept it was willing to entertain.

Classifying and Clustering Trading Agents
The rapid development of sophisticated machine learning methods, together with the increased availability of financial data, has the potential to transform financial research, but also poses a challenge in terms of validation and interpretation. A good case study is the task of classifying financial investors based on their behavioral patterns. Not only do we have access to both classification and clustering tools for high-dimensional data, but also data identifying individual investors is fina…
