text: "Let $G$ be a totally disconnected locally compact (tdlc) group. The contraction
group $\\mathrm{con}(g)$ of an element $g\\in G$ is the set of all $h\\in G$ such
that $g^n h g^{-n} \\to 1_G$ as $n \\to \\infty$. The nub of $g$ can then be characterized
as the intersection $\\mathrm{nub}(g)$ of the closures of $\\mathrm{con}(g)$ and
$\\mathrm{con}(g^{-1})$.\r\n Contraction groups and nubs provide important tools
in the study of the structure of tdlc groups, as already evidenced in the work
of G. Willis. It is known that $\\mathrm{nub}(g) = \\{1\\}$ if and only if $\\mathrm{con}(g)$
is closed. In general, contraction groups are not closed and computing the nub
is typically a challenging problem.\r\n Maximal Kac-Moody groups over finite fields
form a prominent family of non-discrete compactly generated simple tdlc groups.
In this paper we give a complete description of the nub of any element in these
groups."

text: Prüfungen sind ein wesentlicher Bestandteil des Mathematikunterrichts. Mündliche
Prüfungsformate sind insbesondere in Abschlussprüfungen üblich, wurden aber bislang
kaum untersucht. Dieses Projekt widmet sich dem Vorkommen und der Bedeutung verschiedener
Wissensarten in mündlichen Prüfungen. Dazu soll auf Grundlage videografierter
Prüfungsgespräche eine Taxonomie für abgefragte Wissensarten entwickelt werden.
Der Vortrag präsentiert die Konzeption sowie erste Ergebnisse einer Vorstudie,
die als Basis für eine vertiefte Analyse realer Prüfungen dient.

text: "Android applications collecting data from users must protect it according
to the current legal frameworks. Such data protection has become even more important
since in 2018 the European Union rolled out the General Data Protection Regulation
(GDPR). Since app developers are not legal experts, they find it difficult to
integrate privacy-aware practices into source code development. Despite these
legal obligations, developers have limited tool support to reason about data protection
throughout their app development process.\r\n This paper explores the use of
static program slicing and software visualization to analyze privacy-relevant
data flows in Android apps. We introduce SliceViz, a web tool that analyzes an
Android app by slicing all privacy-relevant data sources detected in the source
code on the back-end. It then helps developers by visualizing these privacy-relevant
program slices.\r\n We conducted a user study with 12 participants demonstrating
that SliceViz effectively aids developers in identifying privacy-relevant properties
in Android apps.\r\n Our findings indicate that program slicing can be employed
to identify and reason about privacy-relevant data flows in Android applications.
With further usability improvements, developers can be better equipped to handle
privacy-sensitive information."

text: The rapid advancements in digital transformation have led to the emergence
of dataspaces as a pivotal element for industry-wide and cross-industry data integration
and interoperability across various businesses. Despite their potential, the adoption
and effective utilization of dataspaces by business stakeholders remain challenging.
This paper aims to address this gap by developing a comprehensive learning environment
tailored for business stakeholders. Through an interview study and an analysis
of the current state of research, we identify problem fields and derive key requirements
for the development of the learning environment. The proposed environment includes
a demonstrator and a training concept designed to enhance stakeholders' understanding
and capabilities in managing and leveraging dataspaces. Our findings contribute
to the body of knowledge by providing practical guidance through learning environments
for the deployment of dataspaces in business contexts and highlighting areas for
future research.

In [Jalowy, Kabluchko, Marynych, arXiv:2504.11593v1, 2025], the authors discuss a user-friendly approach to determine the limiting empirical zero distribution of a sequence of real-rooted polynomials, as the degree goes to $\infty$. In this note, we aim to apply it to a vast range of examples of polynomials providing a unifying source for limiting empirical zero distributions.
We cover Touchard, Fubini, Eulerian, Narayana and little $q$-Laguerre polynomials as well as hypergeometric polynomials including the classical Hermite, Laguerre and Jacobi polynomials. We construct polynomials whose empirical zero distributions converge to the free multiplicative normal and Poisson distributions. Furthermore, we study polynomials generated by some differential operators. As one inverse result, we derive coefficient asymptotics of the characteristic polynomial of random covariance matrices.

text: The degree of crosslinking in unidirectional prepreg materials was investigated
using differential scanning calorimetry to assess their curing behavior and thermal
characteristics. To complement these measurements with a non-destructive, in-situ
method, the propagation properties of guided acoustic waves in cured carbon fibre-reinforced
epoxy plates were analysed. Correlations between the degree of crosslinking and
acoustically determined mechanical properties were drawn to enable a future non-destructive
evaluation approach.

text: 'Efficient graph processing is essential for a wide range of applications.
Scalability and memory access patterns are still a challenge, especially with
the Breadth-First Search algorithm. This work focuses on leveraging HPC systems
with multiple GPUs available in a single node with peer-to-peer functionality
of the Intel oneAPI implementation of SYCL. We propose three GPU-based load-balancing
methods: work-group localisation for efficient data access, even workload distribution
for higher GPU occupancy, and a hybrid strided-access approach for heuristic balancing.
These methods ensure performance, portability, and productivity with a unified
codebase. Our proposed methodologies outperform state-of-the-art single-GPU implementations
based on CUDA on synthetic RMAT graphs. We analysed BFS performance across NVIDIA
A100, Intel Max 1550, and AMD MI300X GPUs, achieving a peak performance of 153.27
GTEPS on an RMAT25-64 graph using 8 GPUs on the NVIDIA A100. Furthermore, our
work demonstrates the capability to handle RMAT graphs up to scale 29, achieving
superior performance on synthetic graphs and competitive results on real-world
datasets.'

text: "Otus is a high-performance computing cluster that was launched in 2025 and
is operated by the Paderborn Center for Parallel Computing (PC2) at Paderborn
University in Germany. The system is part of the National High Performance Computing
(NHR) initiative. Otus complements the previous supercomputer Noctua 2, offering
approximately twice the computing power while retaining the three node types that
were characteristic of Noctua 2: 1) CPU compute nodes with different memory capacities,
2) high-end GPU nodes, and 3) HPC-grade FPGA nodes. On the Top500 list, which
ranks the 500 most powerful supercomputers in the world, Otus is in position 164
with the CPU partition and in position 255 with the GPU partition (June 2025).
On the Green500 list, ranking the 500 most energy-efficient supercomputers in
the world, Otus is in position 5 with the GPU partition (June 2025).\r\n\r\n\r\nThis
article provides a comprehensive overview of the system in terms of its hardware,
software, system integration, and its overall integration into the data center
building to ensure energy-efficient operation. The article aims to provide unique
insights for scientists using the system and for other centers operating HPC clusters.
The article will be continuously updated to reflect the latest system setup and
measurements. "

text: 'This article provides a comprehensive mathematical-didactic analysis of how
the highly relevant topic symmetry can be prepared for the university education
of PSTs. Methodologically, the analysis is embedded in a design research cycle
and serves as preparation for the actual design of learning activities. The procedure
of "specifying and structuring" learning objects is used and adapted in such a
way that, in addition to mathematical aspects, profession-oriented references
to school mathematics are also considered. An essential result of the analysis
is the formulation of so-called interface aspects to symmetry, which prove to
be helpful in establishing such references. '
