text: In this article, we investigate symmetry properties of distributed systems
of mobile robots. We consider a swarm of n robots in the OBLOT model and analyze
their collective Fsync dynamics using of equivariant dynamical systems theory.
To this end, we show that the corresponding evolution function commutes with rotational
and reflective transformations of R^2. These form a group that is isomorphic to
O(2) x S_n, the product group of the orthogonal group and the permutation on n
elements. The theory of equivariant dynamical systems is used to deduce a hierarchy
along which symmetries of a robot swarm can potentially increase following an
arbitrary protocol. By decoupling the Look phase from the Compute and Move phases
in the mathematical description of an LCM cycle, this hierarchy can be characterized
in terms of automorphisms of connectivity graphs. In particular, we find all possible
types of symmetry increase, if the decoupled Compute and Move phase is invertible.
Finally, we apply our results to protocols which induce state-dependent linear
dynamics, where the reduced system consisting of only the Compute and Move phase
is linear.

text: To facilitate the growing demand for a universal means of digital identification
across services, while preserving user control and privacy, multiple digital identity
implementations have emerged. From a technical perspective, many of these rely
on established concepts within cryptography, allowing them to provide benefits
in terms of security and privacy. Recent legislation also promises broader recognition
and acceptance of digital identities, both in the digital world and beyond. However,
research into the usability, accessibility, and user understanding of digital
identities is rare. We argue that the development of usable digital identity wallets
is vital to the successful and inclusive application of digital identities in
society. In this vision paper, we describe our research plans for obtaining a
better understanding of how to develop these usable digital identities wallets.

text: An r-regular graph is an r-graph, if every odd set of vertices is connected
to its complement by at least r edges. Let G and H be r-graphs. An H-coloring
of G is a mapping such that each r adjacent edges of G are mapped to r adjacent
edges of H. For every , let be an inclusion-wise minimal set of connected r-graphs,
such that for every connected r-graph G there is an which colors G. The Petersen
Coloring Conjecture states that consists of the Petersen graph P. We show that
if true, then this is a very exclusive situation. Our main result is that either
or is an infinite set and if , then is an infinite set. In particular, for all
, is unique. We first characterize and then prove that if contains more than one
element, then it is an infinite set. To obtain our main result we show that contains
the smallest r-graphs of class 2 and the smallest poorly matchable r-graphs, and
we determine the smallest r-graphs of class 2.

text: "In this work, we present a complete characterization of the covariance\r\nstructure
of number statistics in boxes for hyperuniform point processes. Under\r\na standard
integrability assumption, the covariance depends solely on the\r\noverlap of the
faces of the box. Beyond this assumption, a novel interpolating\r\ncovariance
structure emerges. This enables us to identify a limiting Gaussian\r\n'coarse-grained'
process, counting the number of points in large boxes as a\r\nfunction of the
box position. Depending on the integrability assumption, this\r\nprocess may be
continuous or discontinuous, e.g. in d=1 it is given by an\r\nincrement process
of a fractional Brownian motion."

text: Transcripts play a crucial role in qualitative research in computing
education, with significant implications for the credibility and reproducibility
of findings. However, unreflective and inconsistent transcription standards may
unintentionally introduce biases, potentially undermining the validity of research
outcomes and the collective progress of the field. In this article, we introduce
transcription as a theoretically guided process rather than a mere preparatory
step, illustrating its role using a case example. Additionally, through a systematic
review of 107 qualitative research articles in computing education, we identify
widespread shortcomings in the reporting and implementation of transcription practices,
revealing a need for greater intentionality and transparency. To address these
challenges, we propose a three-step framework for selecting, applying, and documenting
transcription standards that align with the specific context and goals of a study.
Rather than advocating for overly complex, one-size-fits-all transcription strategies,
we emphasize the importance of a context-appropriate approach that is clearly
communicated to foster trust and reproducibility. By advancing a more robust transcription
culture, this work aims to support computing education researchers in adopting
standards that enhance the quality and reliability of qualitative research in
the field.

text: The article introduces a method to learn dynamical systems that are governed
by Euler–Lagrange equations from data. The method is based on Gaussian process
regression and identifies continuous or discrete Lagrangians and is, therefore,
structure preserving by design. A rigorous proof of convergence as the distance
between observation data points converges to zero and lower bounds for convergence
rates are provided. Next to convergence guarantees, the method allows for quantification
of model uncertainty, which can provide a basis of adaptive sampling techniques.
We provide efficient uncertainty quantification of any observable that is linear
in the Lagrangian, including of Hamiltonian functions (energy) and symplectic
structures, which is of interest in the context of system identification. The
article overcomes major practical and theoretical difficulties related to the
ill-posedness of the identification task of (discrete) Lagrangians through a careful
design of geometric regularisation strategies and through an exploit of a relation
to convex minimisation problems in reproducing kernel Hilbert spaces.

text: Hypertree decompositions provide a way to evaluate Conjunctive Queries
(CQs) in polynomial time, where the exponent of this polynomial is determined
by the width of the decomposition. In theory, the goal of efficient CQ evaluation
therefore has to be a minimisation of the width. However, in practical settings,
it turns out that there are also other properties of a decomposition that influence
the performance of query evaluation. It is therefore of interest to restrict the
computation of decompositions by constraints and to guide this computation by
preferences. To this end, we propose a novel framework based on candidate tree
decompositions, which allows us to introduce soft hypertree width (shw). This
width measure is a relaxation of hypertree width (hw); it is never greater than
hw and, in some cases, shw may actually be lower than hw. Most importantly, shw
preserves the tractability of deciding if a given CQ is below some fixed bound,
while offering more algorithmic flexibility. In particular, it provides a natural
way to incorporate preferences and constraints into the computation of decompositions.
A prototype implementation and preliminary experiments confirm that this novel
framework can indeed have a practical impact on query evaluation.

text: Despite the advantages that the virtual knowledge graph paradigm has brought
to many application domains, state-of-the-art systems still do not support popular
graph database management systems like Neo4j. Their query rewriting algorithms
focus on languages like conjunctive queries and their unions, which were developed
for relational data and are poorly suited for graph data. Moreover, they also
limit the expressiveness of the ontology languages that admit rewritings, restricting
them to those that enjoy the so-called FO-rewritability property. Rewritings have
thus focused on the DL-Lite family of Description Logics. In this paper, we propose
a technique for rewriting a family of navigational queries for a suitably tailored
fragment of ELHI. Leveraging navigational features in the target query language,
we can include some widely-used axiom shapes not supported by DL-Lite. We implemented
a proof-of-concept prototype that rewrites into Cypher queries, and tested it
on a real-world cognitive neuroscience use case with promising results.
