text: "We present an extremely simple polynomial-space exponential-time\r\n$(1-\\varepsilon)$-approximation
algorithm for MAX-k-SAT that is (slightly)\r\nfaster than the previous known polynomial-space
$(1-\\varepsilon)$-approximation\r\nalgorithms by Hirsch (Discrete Applied Mathematics,
2003) and Escoffier,\r\nPaschos and Tourniaire (Theoretical Computer Science,
2014). Our algorithm\r\nrepeatedly samples an assignment uniformly at random until
finding an\r\nassignment that satisfies a large enough fraction of clauses. Surprisingly,
we\r\ncan show the efficiency of this simpler approach by proving that in any\r\ninstance
of MAX-k-SAT (or more generally any instance of MAXCSP), an\r\nexponential number
of assignments satisfy a fraction of clauses close to the\r\noptimal value."

text: In recent years, nanostructures assembled by DNA have found promising
applications in optics, medicine, and sensing. DNA origami in particular provides
unique self‐assembly properties, not only enabling a vast variety of functionalization
schemes but also presenting a promising route to fabricate large‐scale, bottom‐up
nanostructured arrays. This approach has comparable precision to electron beam
lithography but avoids slow and expensive patterning steps. However, self‐assembly
of lattices with high order and well‐defined periodicity requires careful tuning
of the deposition parameters and interactions involved, which has been done mostly
on mica so far. As mica is not compatible with standard microfabrication processes,
we investigate here the assembly of DNA origami lattices on the most general microfabrication
material, that is, silicon wafers, which has turned out to be rather challenging.
We study how the forming of polycrystalline 2D‐fishnet‐type lattices is influenced
by different incubation conditions and strengths of the origami–origami and origami‐surface
interactions, with the aim to create large‐scale single‐crystalline lattices.
The lattices are characterized by atomic force microscopy and analyzed for precision
of formation, achievable domain size, and surface coverage of well‐formed lattices.
Thanks to the silicon substrate, these DNA origami lattices can be further combined
with traditional microfabrication processes to turn them, for example, into metamaterials
with novel optical properties.

text: Many real-world datasets, such as citation networks, social networks, and
molecular structures, are naturally represented as heterogeneous graphs, where
nodes belong to different types and have additional features. For example, in
a citation network, nodes representing "Paper" or "Author" may include attributes
like keywords or affiliations. A critical machine learning task on these graphs
is node classification, which is useful for applications such as fake news detection,
corporate risk assessment, and molecular property prediction. Although Heterogeneous
Graph Neural Networks (HGNNs) perform well in these contexts, their predictions
remain opaque. Existing post-hoc explanation methods lack support for actual node
features beyond one-hot encoding of node type and often fail to generate realistic,
faithful explanations. To address these gaps, we propose DiGNNExplainer, a model-level
explanation approach that synthesizes heterogeneous graphs with realistic node
features via discrete denoising diffusion. In particular, we generate realistic
discrete features (e.g., bag-of-words features) using diffusion models within
a discrete space, whereas previous approaches are limited to continuous spaces.
We evaluate our approach on multiple datasets and show that DiGNNExplainer produces
explanations that are realistic and faithful to the model's decision-making, outperforming
state-of-the-art methods.

text: "Abstract\r\n The micropolar
continuum is a special case of a micromorphic material model and has additional
degrees of freedom in the form of microrotations compared to the classical continuum.
With the micropolar model, size effects can be considered and the boundary value
problem can be regularized when localization effects occur. In order to map the
microrotations, an additional strain measure and an additional stress are introduced.
For simulation of plasticity, it is possible to define one yield function, and
thus one plastic multiplier as well as one equivalent plastic strain occur. This
approach is known as the single-surface plasticity approach. The macro- and micro-stresses
are coupled in a common flow function. On the other hand, there is the so-called
double-surface plasticity when one yield function, one plastic multiplier, and
one equivalent plastic strain, respectively, are introduced for each of the macro-
and micro-variables. The coupling of the macro- and micro-variables is established
by a possible coupling of both yield functions. The purpose of this paper is to
compare both approaches and to identify similarities and differences."

text: We propose a definition of Coxeter-Dynkin algebras of canonical type generalising
the definition as a path algebra of a quiver. Moreover, we construct two tilting
objects over the squid algebra - one via generalised APR-tilting and one via one-point-extensions
and reflection functors - and identify their endomorphism algebras with the Coxeter-Dynkin
algebra. This shows that our definition gives another representative in the derived
equivalence class of the squid algebra, and hence of the corresponding canonical
algebra. Finally, we have a closer look at the Grothendieck group and the Euler
form which illustrates the connection to Saito's classification of marked extended
affine root systems. On the other hand, this enables us to prove that in the domestic
case Coxeter-Dynkin algebras are of finite representation type.

text: While neural network quantization effectively reduces the cost of matrix multiplications,
aggressive quantization can expose non-matrix-multiply operations as significant
performance and resource bottlenecks on embedded systems. Addressing such bottlenecks
requires a comprehensive approach to tailoring the precision across operations
in the inference computation. To this end, we introduce scaled-integer range analysis
(SIRA), a static analysis technique employing interval arithmetic to determine
the range, scale, and bias for tensors in quantized neural networks. We show how
this information can be exploited to reduce the resource footprint of FPGA dataflow
neural network accelerators via tailored bitwidth adaptation for accumulators
and downstream operations, aggregation of scales and biases, and conversion of
consecutive elementwise operations to thresholding operations. We integrate SIRA-driven
optimizations into the open-source FINN framework, then evaluate their effectiveness
across a range of quantized neural network workloads and compare implementation
alternatives for non-matrix-multiply operations. We demonstrate an average reduction
of 17\% for LUTs, 66\% for DSPs, and 22\% for accumulator bitwidths with SIRA
optimizations, providing detailed benchmark analysis and analytical models to
guide the implementation style for non-matrix layers. Finally, we open-source
SIRA to facilitate community exploration of its benefits across various applications
and hardware platforms.

text: "Zusammenfassung\r\n Risikokompetenz
beinhaltet auch die Fähigkeit, stochastische Informationen, wie beispielsweise
Anteile und Wahrscheinlichkeiten, richtig zu versprachlichen. Aus der Forschung
zu bedingten Wahrscheinlichkeiten und Bayesianischen Aufgaben ist bekannt, dass
die Nutzung von Visualisierungen und sogenannten „natürlichen Häufigkeiten“ (z. B.
„80 von 100 Personen“) statt Wahrscheinlichkeiten in Prozent Verwechslungen beim
Bestimmen von Wahrscheinlichkeiten eindämmen kann. Über den umgekehrten Prozess
– das Versprachlichen von in Visualisierungen dargestellten Informationen – ist
bisher jedoch wenig bekannt, obwohl diese Versprachlichungen auch für den Aufbau
konzeptuellen Wissen als essentiell angesehen werden. In der vorliegenden Studie
wurde daher untersucht, wie gut Schüler:innen die Versprachlichung von in Visualisierungen
dargestellten Anteilen und natürlichen Häufigkeiten gelingt. Dazu wurde mit 138
Realschüler:innen aus der 9. Jahrgangsstufe ein Papier-und-Bleistift-Test durchgeführt,
bei dem den Teilnehmenden nacheinander je ein (vollständig ausgefülltes) Baumdiagramm
und ein Netzdiagramm präsentiert wurde. Die Schüler:innen sollten die inhaltliche
Bedeutung der in der Visualisierung dargestellten stochastischen Informationen
möglichst genau versprachlichen. Fokus der Studie ist der Einfluss der Visualisierung
(Baumdiagramm vs. Netzdiagramm) und des Informationsformats der Visualisierung
(Anteile in Prozent vs. natürliche Häufigkeiten) auf die richtige Versprachlichung
von verschiedenen Relationstypen (Schnittinformationen vs. bedingte Informationen).
Die Ergebnisse zeigen unter anderem, dass Informationen in natürlichen Häufigkeiten
deutlich besser versprachlicht werden als in Prozenten und dass Schnittinformationen
in Prozent besser anhand von Netzdiagrammen als von Baumdiagrammen versprachlicht
werden. Die gewonnenen Erkenntnisse geben überdies Einblicke in typische (fehlerhafte)
Versprachlichungen von Schüler:innen und könnten als Basis für die Entwicklung
eines sprachsensiblen Unterrichts zu Anteilen und Wahrscheinlichkeiten im schulischen
Stochastikunterricht dienen."

text: "This paper deals with the development and results of a prediction framework
for traffic light control systems as well as the usage and benefits of such predictions
in green light optimal speed advisory (GLOSA) scenarios.\r\nVarious machine learning
methods like support vector machines, neural networks or reinforcement learning
were evaluated for their applicability in the prediction context and compared
based on their efficiency and most importantly accuracy. The resulting prediction
framework uses decision tree ensemble models combined with certain model knowledge
to forecast different control strategies. This method was chosen due to its best
performance in various test scenarios. Very high accuracy and fidelity were achieved
for standard control methods like fixed-time, time-of-day-based and 'ordinary'
traffic-based programs. Only for the more sophisticated model predictive control
which was tested lower accuracies were achieved.\r\nFor the upcoming GLOSA application
the penetration of equipped vehicles was varied for different traffic scenarios
and control strategies. Results showcase high potentials for enhancing urban mobility
and reducing environmental impact by lower emissions and waiting times. However,
it is also clear from the studies presented in this contribution that the coordination
of the control strategy with the GLOSA vehicles is of enormous importance."

text: "\r\n Purpose\r\n The
adoption of laser powder bed fusion (LPBF) as an additive manufacturing technique
has been slow in the oil and gas (O&G) industry because of the uncertainty
regarding material performance and the lack of suitable materials. The high investment
and time required for LPBF development also discourage adoption. This study aims
to address these concerns by developing a parameter set for a relevant material
using a systematic approach to optimize the density of the printed parts with
reduced experimental effort.\r\n \r\n \r\n
\ Design/methodology/approach\r\n First,
an industry-relevant Ni-based superalloy, UNS N09946, was gas-atomized to produce
a powder. The powder was fully characterized to ensure successful printing. Next,
a processing parameter set tailored for achieving full density was developed for
UNS N09946 using a Design of Experiments (DoE) approach based on the volumetric
energy density equation.\r\n \r\n \r\n
\ Findings\r\n A
model was created using Response Surface Methodology that relates laser power,
scan speed and hatch distance to efficiently identify successful parameter combinations,
thus reducing the number of specimens necessary for the successful manufacturing
of UNS N09946 using LPBF. A part density of 99.9% was achieved using this method.\r\n
\ \r\n \r\n Originality/value\r\n
\ This study applies an existing experimental design
method to a never-before-printed material. The reduced experimental effort through
this method and lessons learned from the gas atomization process can be directly
applied to other materials in and outside the O&G industry to further the
adoption of LPBF as a serious manufacturing technology.\r\n "
