text: "We study a block mean-field Ising model with $N$ spins split into $s_N$ blocks,
with Curie-Weiss interaction within blocks and nearest-neighbor coupling between
blocks. While previous models deal with the block magnetization for a fixed number
of blocks, we study the the simultaneous limit $N\\to\\infty$ and $s_N\\to\\infty$.
The model interpolates between Curie-Weiss model for $s_N=1$, multi-species mean
field for fixed $s_N=s$, and the 1D Ising model for each spin in its own block
at $s_N=N$.\r\n Under mild growth conditions on $s_N$, we prove a law of large
numbers and a multivariate CLT with covariance given by the lattice Green's function.
For instance, the high temperature CLT essentially covers the optimal range up
to $s_N=o(N/(\\log N)^c)$ and the low temperature regime is new even for fixed
number of blocks $s > 2$. In addition to the standard competition between entropy
and energy, a new obstacle in the proofs is a curse of dimensionality as $s_N
\\to \\infty$."

text: We provide a method to systematically construct vector fields for which the
dynamics display transitions corresponding to a desired hierarchical connection
structure. This structure is given as a finite set of directed graphs $\mathbf{G}_1,\dotsc,\mathbf{G}_N$
(the lower level), together with another digraph $\mathbfΓ$ on $N$ vertices (the
top level). The dynamic realizations of $\mathbf{G}_1,\dotsc,\mathbf{G}_N$ are
heteroclinic networks and they can be thought of as individual connection patterns
on a given set of states. Edges in $\mathbfΓ$ correspond to transitions between
these different patterns. In our construction, the connections given through $\mathbfΓ$
are not heteroclinic, but excitable with zero threshold. This describes a dynamical
transition between two invariant sets where every $δ$-neighborhood of the first
set contains an initial condition with $ω$-limit in the second set. Thus, we prove
a theorem that allows the systematic creation of hierarchical networks that are
excitable on the top level, and heteroclinic on the lower level. Our results modify
and extend the simplex realization method by Ashwin & Postlethwaite.

text: 'Large Language Models (LLMs) have demonstrated remarkable performance across
a wide range of natural language processing tasks. However, their effectiveness
in low-resource languages remains underexplored, particularly in complex tasks
such as end-to-end Entity Linking (EL), which requires both mention detection
and disambiguation against a knowledge base (KB). In earlier work, we introduced
IndEL — the first end-to-end EL benchmark dataset for the Indonesian language
— covering both a general domain (news) and a specific domain (religious text
from the Indonesian translation of the Quran), and evaluated four traditional
end-to-end EL systems on this dataset. In this study, we propose ELEVATE-ID, a
comprehensive evaluation framework for assessing LLM performance on end-to-end
EL in Indonesian. The framework evaluates LLMs under both zero-shot and fine-tuned
conditions, using multilingual and Indonesian monolingual models, with Wikidata
as the target KB. Our experiments include performance benchmarking, generalization
analysis across domains, and systematic error analysis. Results show that GPT-4
and GPT-3.5 achieve the highest accuracy in zero-shot and fine-tuned settings,
respectively. However, even fine-tuned GPT-3.5 underperforms compared to DBpedia
Spotlight — the weakest of the traditional model baselines — in the general domain.
Interestingly, GPT-3.5 outperforms Babelfy in the specific domain. Generalization
analysis indicates that fine-tuned GPT-3.5 adapts more effectively to cross-domain
and mixed-domain scenarios. Error analysis uncovers persistent challenges that
hinder LLM performance: difficulties with non-complete mentions, acronym disambiguation,
and full-name recognition in formal contexts. These issues point to limitations
in mention boundary detection and contextual grounding. Indonesian-pretrained
LLMs, Komodo and Merak, reveal core weaknesses: template leakage and entity hallucination,
respectively—underscoring architectural and training limitations in low-resource
end-to-end EL.11Code and dataset are available at https://github.com/dice-group/ELEVATE-ID.'

text: Structural measures of graphs, such as treewidth, are central tools in computational
complexity resulting in efficient algorithms when exploiting the parameter. It
is even known that modern SAT solvers work efficiently on instances of small treewidth.
Since these solvers are widely applied, research interests in compact encodings
into (Q)SAT for solving and to understand encoding limitations. Even more general
is the graph parameter clique-width, which unlike treewidth can be small for dense
graphs. Although algorithms are available for clique-width, little is known about
encodings. We initiate the quest to understand encoding capabilities with clique-width
by considering abstract argumentation, which is a robust framework for reasoning
with conflicting arguments. It is based on directed graphs and asks for computationally
challenging properties, making it a natural candidate to study computational properties.
We design novel reductions from argumentation problems to (Q)SAT. Our reductions
linearly preserve the clique-width, resulting in directed decomposition-guided
(DDG) reductions. We establish novel results for all argumentation semantics,
including counting. Notably, the overhead caused by our DDG reductions cannot
be significantly improved under reasonable assumptions.

text: We introduce the notion of contrastive ABox explanations to answer questions
of the type "Why is a an instance of C, but b is not?". While there are various
approaches for explaining positive entailments (why is C(a) entailed by the knowledge
base) as well as missing entailments (why is C(b) not entailed) in isolation,
contrastive explanations consider both at the same time, which allows them to
focus on the relevant commonalities and differences between a and b. We develop
an appropriate notion of contrastive explanations for the special case of ABox
reasoning with description logic ontologies, and analyze the computational complexity
for different variants under different optimality criteria, considering lightweight
as well as more expressive description logics. We implemented a first method for
computing one variant of contrastive explanations, and evaluated it on generated
problems for realistic knowledge bases.

text: Room-temperature lasing is a key milestone in the development of miniaturized
optoelectronic and photonic devices. We present a simple approach to synthesize
phase-pure quasi-2D layered tin perovskite nanowires with varying quantum well
thicknesses (n = 1 to 4). By incorporating a new organic spacer capable of forming
a hydrogen-bonded organic framework, this method promoted anisotropic crystal
growth and enhanced lattice rigidity. Furthermore, introducing molecular intercalants
enabled controlled crystallization into well-defined nanowires that function as
Fabry–Pérot cavities. Cavities made from n = 2 to 4 perovskites support efficient
and robust near-infrared, room-temperature optically pumped lasing with the threshold
as low as 75.8 μJ/cm2, cavity quality factor over 3000, and negligible degradation
over 106 pulses. A cleaved coupled nanolaser was fabricated as a proof-of-concept
device for photonic applications.

text: We discretise a recently proposed new Lagrangian approach to optimal control
problems with dynamics described by force-controlled Euler-Lagrange equations
(Konopik et al., in Nonlinearity 38:11, 2025). The resulting discretisations are
in the form of discrete Lagrangians. We show that the discrete necessary conditions
for optimality obtained provide variational integrators for the continuous problem,
akin to Karush-Kuhn-Tucker (KKT) conditions for standard direct approaches. This
approach paves the way for the use of variational error analysis to derive the
order of convergence of the resulting numerical schemes for both state and costate
variables and to apply discrete Noether’s theorem to compute conserved quantities,
distinguishing itself from existing geometric approaches. We show for a family
of low-order discretisations that the resulting numerical schemes are ‘doubly-symplectic’,
meaning they yield forced symplectic integrators for the underlying controlled
mechanical system and overall symplectic integrators in the state-adjoint space.
Multi-body dynamics examples are solved numerically using the new approach. In
addition, the new approach is compared to standard direct approaches in terms
of computational performance and error convergence. The results highlight the
advantages of the new approach, namely, better performance and convergence behaviour
of state and costate variables consistent with variational error analysis and
automatic preservation of certain first integrals.

text: "Current legal frameworks enforce that Android developers accurately report
the data their apps collect. However, large codebases can make this reporting
challenging. This paper employs an empirical approach to understand developers'
experience with Google Play Store's Data Safety Section (DSS) form.\r\n\r\nWe
first survey 41 Android developers to understand how they categorize privacy-related
data into DSS categories and how confident they feel when completing the DSS form.
To gain a broader and more detailed view of the challenges developers encounter
during the process, we complement the survey with an analysis of 172 online developer
discussions, capturing the perspectives of 642 additional developers. Together,
these two data sources represent insights from 683 developers.\r\n\r\nOur findings
reveal that developers often manually classify the privacy-related data their
apps collect into the data categories defined by Google-or, in some cases, omit
classification entirely-and rely heavily on existing online resources when completing
the form. Moreover, developers are generally confident in recognizing the data
their apps collect, yet they lack confidence in translating this knowledge into
DSS-compliant disclosures. Key challenges include issues in identifying privacy-relevant
data to complete the form, limited understanding of the form, and concerns about
app rejection due to discrepancies with Google's privacy requirements.\r\nThese
results underscore the need for clearer guidance and more accessible tooling to
support developers in meeting privacy-aware reporting obligations. "

text: We investigate homogeneous coupled cell systems with high-dimensional internal
dynamics. In many studies on network dynamics, the analysis is restricted to networks
with one-dimensional internal dynamics. Here, we show how symmetry explains the
relation between dynamical behavior of systems with one-dimensional internal dynamics
and with higher dimensional internal dynamics, when the underlying network topology
is the same. Fundamental networks of homogeneous coupled cell systems (B. Rink,
J. Sanders. Coupled Cell Networks and Their Hidden Symmetries. SIAM J. Math. Anal.
46.2 (2014)) can be expressed in terms of monoid representations, which uniquely
decompose into indecomposable subrepresentations. In the high-dimensional internal
dynamics case, these subrepresentations are isomorphic to multiple copies of those
one computes in the one-dimensional internal dynamics case. This has interesting
implications for possible center subspaces in bifurcation analysis. We describe
the effect on steady state and Hopf bifurcations in l-parameter families of network
vector fields. The main results in that regard are that (1) generic one-parameter
steady state bifurcations are qualitatively independent of the dimension of the
internal dynamics and that, (2) in order to observe all generic l-parameter bifurcations
that may occur for internal dynamics of any dimension, the internal dynamics has
to be at least l-dimensional for steady state bifurcations and 2l-dimensional
for Hopf bifurcations. Furthermore, we illustrate how additional structure in
the network can be exploited to obtain even greater understanding of bifurcation
scenarios in the high-dimensional case beyond qualitative statements about the
collective dynamics. One-parameter steady state bifurcations in feedforward networks
exhibit an unusual amplification in the asymptotic growth rates of individual
cells, when these are one-dimensional (S. von der Gracht, E. Nijholt, B. Rink.
Amplified steady state bifurcations in feedforward networks. Nonlinearity 35.4
(2022)). As another main result, we prove that (3) the same cells exhibit this
amplifying effect with the same growth rates when the internal dynamics is high-dimensional.

text: Static Application Security Testing (SAST) tools play a vital role in modern
software development by automatically detecting potential vulnerabilities in source
code. However, their effectiveness is often limited by a high rate of false positives,
which wastes developer's effort and undermines trust in automated analysis. This
work presents a Graph Convolutional Network (GCN) model designed to predict SAST
reports as true and false positive. The model leverages Code Property Graphs (CPGs)
constructed from static analysis results to capture both, structural and semantic
relationships within code. Trained on the CamBenchCAP dataset, the model achieved
an accuracy of 100% on the test set using an 80/20 train-test split. Evaluation
on the CryptoAPI-Bench benchmark further demonstrated the model's practical applicability,
reaching an overall accuracy of up to 96.6%. A detailed qualitative inspection
revealed that many cases marked as misclassifications corresponded to genuine
security weaknesses, indicating that the model effectively reflects conservative,
security-aware reasoning. Identified limitations include incomplete control-flow
representation due to missing interprocedural connections. Future work will focus
on integrating call graphs, applying graph explainability techniques, and extending
training data across multiple SAST tools to improve generalization and interpretability.
