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: 'We investigate how verbal and nonverbal linguistic features, exhibited by
speakers and listeners in dialogue, can contribute to predicting the listener''s
state of understanding in explanatory interactions on a moment-by-moment basis.
Specifically, we examine three linguistic cues related to cognitive load and hypothesised
to correlate with listener understanding: the information value (operationalised
with surprisal) and syntactic complexity of the speaker''s utterances, and the
variation in the listener''s interactive gaze behaviour. Based on statistical
analyses of the MUNDEX corpus of face-to-face dialogic board game explanations,
we find that individual cues vary with the listener''s level of understanding.
Listener states (‘Understanding’, ‘Partial Understanding’, ‘Non-Understanding’
and ‘Misunderstanding’) were self-annotated by the listeners using a retrospective
video-recall method. The results of a subsequent classification experiment, involving
two off-the-shelf classifiers and a fine-tuned German BERT-based multimodal classifier,
demonstrate that prediction of these four states of understanding is generally
possible and improves when the three linguistic cues are considered alongside
textual features.'

text: 'Intersection distribution and non-hitting index are concepts introduced recently
by Li and Pott as a new way to view the behaviour of a collection of finite field
polynomials. With both an algebraic interpretation via the intersection of a polynomial
with a set of lines, and a geometric interpretation via a (q+1)-set possessing
an internal nucleus, the concepts have proved their usefulness as a new way to
view various long-standing problems, and have applications in areas such as Kakeya
sets. In this paper, by exploiting connections with diverse areas including the
theory of algebraic curves, cyclotomy and the enumeration of irreducible polynomials,
we establish new results and resolve various Open Problems of Li and Pott. We
prove geometric results which shed new light on the relationship between intersection
distribution and projective equivalence of polynomials, and algebraic results
which describe and characterise the degree of Sf - the index of the largest non-zero
entry in the intersection distribution of f. We provide new insights into the
non-hitting spectrum, and show the limitations of the non-hitting index as a tool
for characterisation. Finally, the benefits provided by the connections to other
areas are evidenced in two short new proofs of the cubic case. '

text: Grocery retailers frequently apply price discounts to stimulate demand for
expiring perishables. However, integrating these discounted sales into future
demand forecasts presents a significant challenge. This study investigates the
effectiveness of incorporating a fixed share of these sales as \textit{regular}
demand into the forecast, as commonly applied in practice. We employ a two-step
regression approach on data from a major European grocery retailer, covering over
1,700 products across 676 stores. We reveal that forecasts underestimate actual
demand for most SKUs when discounted sales occur. This residual uplift effect
is significantly influenced by the number of sales at reduced prices. Our findings
underscore the necessity for more precise approaches to integrate discounted sales
into demand forecasts, thereby preventing excess inventory and the associated
economic and environmental impacts of spoilage in the grocery sector.

text: 'Traditional dyadic customer-provider interactions are being shifted to polyadic
interactions involving diverse participants in digital service ecosystems. Especially,
artificial intelligence (AI) is increasingly integrated into these ecosystems,
so that they comprise non-human participants (e.g., AI-based chatbots)—fundamentally
altering the nature of value (co-)creation. While existing literature examines
human-to-human interactions, knowledge of service interactions between human actors
and AI-based systems is still underexplored. To address this research gap, we
develop a taxonomy, comprising six iterations, that explores the peculiarities
of AI as either a resource or a (non-human) agent in digital service ecosystems.
We evaluate our taxonomy using a multiple case study and derive the four archetypes
of AI in digital service ecosystems: (1) discriminative experience enhancer, (2)
protective ecosystem orchestrator, (3) ecosystem innovation companion, and (4)
personalized service composer. Our results extend the knowledge on service science
by showing how AI-based systems—discriminative or generative, and focusing on
the interaction in the ecosystem or the individual service encounter—assume the
role of resources and non-human agents. Researchers and practitioners can utilize
our results to augment their ecosystems with AI.'

text: We present recent progress made towards ultra-broadband photonically assisted
analog-to-digital converters, that leverage both the low jitter of best-of-class
mode-locked lasers as well as the capability of optics to break down broadband
signals into multiple lower speed tributaries that can be better handled by electronics.
We review in particular our work on both time- and frequency-domain approaches
and give an outlook on how these architectures can be extended to include further
signal processing tasks such as equalization. Optically triggered track-and-hold
amplifiers are reported with an equivalent jitter below 80 fs rms in a signal
frequency range from 20 GHz to 70 GHz. Frequency-domain architectures implementing
optical arbitrary waveform measurement up to signal bandwidths of 610 GHz are
also shown. Finally, an architecture allowing the deserialization and equalization
of PAM4 signals is introduced and modeled for operation in 400 Gb/s links.

text: Integrated photonic-assisted signal processing has multiple applications such
as signal amplification, multiplexing, and high-Q filtering in optical communication
systems, optical sensing systems, and also microwave photonics. We will review
recent works on integrated photonic-assisted signal processing for sinc-shaped
Nyquist pulse generation, high-bandwidth Nyquist signal detection with low bandwidth
devices, arbitrary waveform generation and measurement, and on-chip photonic frequency
decoding. However, in such photonic integrated circuits (PICs), the photonic components
are placed very close to each other on the chip, resulting in thermal crosstalk
which degrades the system performance. Air-filled oxide and deep trench designs
have proven to be very effective in mitigating the thermal crosstalk for various
frequently deployed photonic devices like Mach-Zehnder modulators (MZMs), ring
resonators, optical switches, and photodetectors designed on a standard silicon-on-insulator
(SOI) platform. In this chapter, we will additionally review the basics of optical
signal processing and some results for such trench-enhanced thermal crosstalk
resilient circuits.

text: High-speed ADCs operating in the tens of gigahertz up to potentially terahertz
range are largely constrained by the jitter in their clock sources. By incorporating
photonically assisted samplers that exploit the ultralow jitter of specific mode-locked
lasers (MLLs) as analogue ADC frontends, the performance limits of data converters
can be pushed to achieve unprecedented levels of accuracy. Continuous advancements
in electronic-photonic integration (silicon photonics) are clearing the path for
integrating these systems on a chip scale, thereby leading to increased scalability,
as well as reduced cost and power consumption.

text: This chapter explores the crucial role of simulation and modelling of electronic
and photonic components for terahertz (THz) systems. THz-related challenges already
begin with setting up the signal generation and sampling parameters and continue
with the realistic modelling of the electronic and photonic building blocks. Hereby,
photonic components require not only the modelling of the optical signal propagation
but also the modelling of the electronic interface in the THz regime. Furthermore,
when advancing to the simulation of systems like fully integrated electronic transmit
and receive frontends or photonically assisted analogue-to-digital converters
(ADCs), it is up to the designer to find a suitable level of abstraction. Size,
complexity, and available computational power versus accuracy must be taken into
consideration and prioritized against each other.

Berufsausübung abzielt. Wir fassen die forschende Grundhaltung als Professionsüberzeugung,
die aus einer kognitiven, affektiven und handlungsbezogenen Komponente besteht
und untersuchen die Komponenten im Zusammenspiel sowie im Längsschnitt.\r\n
\ Mittels teilstrukturierter Interviews mit 22 angehenden Lehrkräften
im Referendariat und Berufseinstieg, die sich im Praxissemester mit Forschendem
Lernen befasst haben, werden das Verständnis (kognitive Komponente) und die Bedeutsamkeit
(affektive und handlungsbezogene Komponente) Forschenden Lernens in der jeweiligen
Ausbildungs- bzw. Berufsphase erfragt. Die Daten werden inhaltsanalytisch sowie
typenbildend ausgewertet, um das Verständnis und die Bedeutsamkeit in der jeweiligen
Phase, längsschnittliche Entwicklungen sowie das Verhältnis von Verständnis und
Bedeutsamkeit herauszuarbeiten. Die Befunde zeigen, dass die Verständnisse von
Forschendem Lernen sowohl im Referendariat als auch im Berufseinstieg variieren.
Zudem ist das Konzept – laut Schilderungen der Befragten – durchaus bedeutsam
für ihre Lern- und Handlungspraxis, jedoch nicht für alle und in unterschiedlich
ausgeprägter Form. Die Typenbildung verdeutlicht, dass die fehlende Bedeutsamkeit
Forschenden Lernens mit Fehlkonzepten einhergeht und eine höhere Bedeutsamkeit
erkennbar ist, wenn Adaptionsleistungen hinsichtlich des Konzepts vorgenommen
werden. Insgesamt ist im Sinne der Auffassung als Professionsüberzeugung die Anbahnung
einer forschenden Grundhaltung bei einigen Befragten erkennbar. Implikationen
für eine künftige Hochschulbildung ergeben sich u. a. mit Blick auf die Unterstützung
von Studierenden bei Adaptionsleistungen für die (jeweilige) Praxis."
