text: "Abstract\r\n This study
investigates how secondary students construct and evaluate decision trees in an
open exploratory task using CODAP. By analyzing students’ tree products and oral
self-reports, we identified different data-based and context-based approaches
to predictor selection and stopping criteria. Students engaged with key ideas
of predictive modeling, including classification, model construction, accuracy,
generalization, and interpretability. Informal exploration offered rich opportunities
for subsequent teaching by enabling students to begin reconstructing central technical
ideas and critical tensions of predictive modeling through diverse but meaningful
reasoning approaches."

text: We investigate generalisations of 1-factorisations and hyperfactorisations
of the complete graph $K_{2n}$. We show that they are special subsets of the association
scheme obtained from the Gelfand pair $(S_{2n},S_2 \wr S_n)$. This unifies and
extends results by Cameron (1976) and gives rise to new existence and non-existence
results. Our methods involve working in the group algebra $\mathbb{C}[S_{2n}]$
and using the representation theory of $S_{2n}$.

text: Resilient systems require monitoring and prediction of environmental and intrinsic
conditions and the ability to adapt to changing circumstances to optimize the
trade-off between performance, power consumption, and fault tolerance. TETRISC
was introduced as a resilient multicore RISC-V processor system based on the PULPissimo
platform. This paper presents the migration of TETRISC to the Rocket Chip SoC,
which is freely scalable to the number of processors through parametrizable Chisel
models. As such, we discuss and evaluate the main advantages and obstacles that
come with the Chipyard framework for RTL simulation and FPGA synthesis for the
rapid prototyping of resilient, scalable architectures that are online configurable
through software for different multicore and lock-step modes.

text: "In this work, we build a bridge between the Pólya--Schur program and Voiculescu's
free probability theory. A cornerstone of the former is the Pólya--Benz Theorem,
classifying a central family of real-root preserving operators on the space of
polynomials, as those given by $f(\\partial_z)$ for a Laguerre--Pólya function
$f$ and the derivative operator $\\partial_{z}$. We prove that any free (additive)
infinitely divisible distribution can be attained as the weak limit of root distributions
of Appell polynomials $f_n(\\partial_z)z^n$ as $n\\to\\infty$, for a suitably
chosen sequence $f_n$ of Laguerre--Pólya functions.\r\n Such questions on the
(global) limiting distributions of real rooted polynomials belong to the active
research area of finite free probability. In contrast to its standard tools, our
approach allows for non-compactly supported limiting distributions, (barely) complex
rooted polynomials and even provides the full microscopic description of the roots.
Moreover, we extend our results to differential operators generating free multiplicative
infinitely divisible distributions, to the rectangular free convolution, and to
$f_n(\\partial_z)p_n$ for real rooted polynomials $p_n$, implying a generalization
of the recent connections between the heat flow and free Brownian motion to any
free Lévy process.\r\n As corollaries, we identify free stable distributions
by choosing $f_n$ to be a fixed rescaled Laguerre--Pólya function, and we prove
various convergence results on the zero distributions of Jensen polynomials, e.g.
the limiting root distribution of Jensen polynomial of the Riemann $Ξ$-function
is given by the Cauchy distribution."

text: With a range of consumer devices available, augmented reality (AR) continues
to make its way into everyday life and is also increasingly used in professional
and sensitive contexts. Especially collaborative use cases, such as remote meetings
or maintenance, offer potential, but also move issues in the area of privacy and
security into focus. We conducted a scoping review to gain an overview of the
current situation and found a lack of clear standards, with most approaches focusing
on single protection features. Using the knowledge from the scoping review, we
set up and conducted expert interviews. They revealed that end-users are almost
completely dependent on developers or device manufacturers regarding their options
for protection. The interviews also showed that most developers put little focus
on privacy and security, often due to external constraints, such as employers
treating the topic as an “afterthought” and not budgeting enough time for it.
The experts suggested offering better software support to developers to enable
the inclusion of privacy and security with less overhead as a solution. It was
also suggested that a general rise in privacy and security awareness could improve
the overall situation.

abstract:
- lang: eng
text: "We generalize intersection numbers for combinatorial designs to designs in
finite meet-semilattices satisfying suitable regularity conditions. While designs
in regular semilattices go back to Delsarte, our regularity assumptions are weaker
than his and need not give rise to an association scheme. In this framework, we
extend Mendelsohn's equations, prove a generalized Singleton bound with Steiner
systems as equality cases, and determine the block intersection distribution at
any block of a Steiner system. In particular, this distribution is independent
of the chosen block.\r\n Specializing to several classical semilattice families,
our results recover a number of well-known distributions in coding and design
theory. In the Hamming and the $q$-Hamming (or bilinear forms) schemes, they give
the local distance distributions of MDS and MRD codes, respectively. In the Johnson
and $q$-Johnson (or Graßmann) schemes, they reproduce the block intersection distribution
of classical and $q$-analog Steiner systems, equivalently the distance distribution
of diameter-perfect constant-weight codes and diameter-perfect constant-dimension
subspace codes. For the $q$-Johnson schemes, to the best of our knowledge, this
result is new. As a further illustration, we apply our theory to designs of perfect
matchings.\r\n Our approach provides a unified treatment of these cases in the
strongest form known in the literature, determining the distribution relative
to each individual block or codeword, without averaging and without linearity
or additivity assumptions. Moreover, it identifies the natural double-counting
objects underlying these distributions, leading to formulas in the regularity
parameters of the semilattice and avoiding the more cumbersome expressions that
arise in eigenvalue-based approaches via the ambient association scheme."
