  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: "<jats:title>Zusammenfassung</jats:title>\r\n                  <jats:p>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.</jats:p>"

  text: Abstract This study explores the usability and onboarding process of a Mixed
    Reality (MR) application called PEARL, designed to prepare students for laboratory
    work. Originally developed for mobile Augmented Reality (mAR), PEARL was adapted
    for MR to offer a more immersive and intuitive experience through hand and gesture
    controls. Since many students lack experience with MR devices, a user-friendly
    onboarding system is essential. The study aims to redesign PEARL’s user interface
    and onboarding experience, evaluating how intuitive interaction elements impact
    usability. First, a literature review will identify existing usability guidelines
    for MR applications, which will guide the redesign of the interface. This new
    version will then be tested with students through a user study. Feedback will
    be collected via an online survey to assess the onboarding and user experience,
    and the findings will be used to refine the design further. The expected outcome
    is an improved onboarding process and interface, making PEARL accessible even
    for MR novices, enhancing their ability to interact with 3D objects in a real-world
    setting. Ultimately, the study aims to provide best practices for developing intuitive
    MR interfaces and effective onboarding experiences, especially in educational
    contexts.

  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>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.</jats:p>"

    assisted digital-to-analog converters (DACs) using Nyquist pulse sequences (NPSs)
    are presented and investigated. Therefore, NPSs are mathematically described and
    analyzed. Based on this, the operating principle of a precise optical Nyquist
    pulse synthesizer digital-to-analog converter (PONyDAC) is described. Possible
    architectures of PONyDAC are derived and compared in terms of performance and
    practicability. Moreover, the limits of PONyDAC systems and their superiority
    over classical electronic DACs are discussed. Furthermore, discrete building-block
    based implementations and monolithic implementations in electronic-photonic integrated
    circuits (EPICs) are presented. To enable a practicable monolithic integration,
    a shrinkage of the Mach-Zehnder modulators (MZMs) has been performed by applying
    forward-biased phase shifters (FB-PSs). These FB-PSs are analyzed and modeled
    to allow the precise and reliable design of PONyDAC systems with multiple MZMs.
    Finally, data conversion and data transmission experiments are carried out to
    demonstrate the systems functionality, quantify its performance, and prove their
    superiority over purely electronic DACs.</jats:p>"

    algorithm for cutting solid objects in a topology‐controlled manner is presented.
    Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded
    by the loop is constructed in the interior. In contrast to various previous approaches,
    both disk topology and conformance to the prescribed loop are ensured by construction,
    while supporting not only contractible but also incontractible loops on the boundaries
    of manifold objects of higher genus and arbitrary non‐trivial topology. We describe
    an implementation of this algorithm in the discrete setting, with triangle mesh
    cut surfaces embedded in tetrahedral mesh objects. Making use of this novel cutting
    algorithm, we describe a method for the reliable construction of bijective volumetric
    maps between solid objects, demonstrating the algorithm's utility. This mapping
    method overcomes restrictions of the state of the art to topological balls, extending
    coverage to objects of arbitrary genus, specifically so‐called\r\n                    <jats:italic>1</jats:italic>\r\n

  text: "<jats:p>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\r\nimplemented a
    first method for computing one variant of contrastive explanations, and evaluated
    it on generated problems for realistic knowledge bases.</jats:p>"

  text: '<jats:title>Abstract</jats:title><jats:p>In this symposium we investigate
    students’ agency of selecting and using (digital) resources for developing their
    own learning paths. For that, we first review the literature related to students’
    selection and use of resources in mathematics education in different pedagogical
    settings (presentation 1). Second, we develop insights from the different studies
    that participate in this symposium (presentation 2–6), at school as well as at
    university level. Results show that attempts have been made to provide students
    opportunities to develop agency of their mathematics learning, in particular with
    the development and provision of numerous digital tools and learning resources
    at university level and related to innovative pedagogical approaches. At the same
    time, it is not obvious how these tools and resources help students to develop
    deeper conceptual understandings. Certainly, students often ‘demand’ more student-centered
    and autonomous education approaches (e.g., at university level), also in mathematics
    education. Further, it seems that authentic problem-based education approaches
    are more motivating for students. These ‘innovative’ approaches necessitate particular
    types of structure and support for students. Moreover, they require different
    ways of providing resources that students can and want to interact with, and that
    help students to navigate through the curriculum to develop their own learning
    paths. At the same time, teachers also need support on how to orchestrate student
    learning with the available resources in such environments, so to be able to attend
    to students’ individual needs. The symposium comprised altogether six presentations:</jats:p><jats:p>Birgit

  text: "<jats:title>Abstract</jats:title>\r\n          <jats:p>Statistics and machine
    learning are critical because they play an essential role in our everyday lives
    and the careers we may pursue in the future. It may be beneficial to introduce
    machine learning, such as decision trees (DTs), at an early stage of education.
    The data-based construction of DTs is an example of a machine learning process,
    which can be addressed in mathematics or statistics teaching because of relatively
    low prior knowledge requirements. This paper focuses on investigating how sixth-grade
    students create and evaluate data-based DTs. The basis is a teaching unit that
    aims to lay the foundation for machine learning and enhance students’ understanding
    of the process. We investigate students’ processes in detail while they build
    DTs with data cards about food items to predict whether a new item is recommendable.
    After the teaching unit, an interview study examines students’ strategies for
    creating decision trees. The findings contribute to understanding students’ learning
    processes and the challenges when working with decision trees.</jats:p>"

  text: In the last decade, there has been increasing interest in allowing users to
    understand how the predictions of machine-learned models come about, thus increasing
    transparency and empowering users to understand and potentially contest those
    decisions.Dialogue-based approaches, in contrast to traditional one-shot eXplainable
    Artificial Intelligence (XAI) methods, facilitate interactive, in-depth exploration
    through multi-turn dialogues, simulating expert conversations. This paper reviews
    the current state of dialogue-based XAI, presenting a systematic review of 1,339
    publications, narrowed down to 14 based on inclusion criteria. We explore theoretical
    foundations of the systems, propose key dimensions along which different solutions
    to dialogue-based XAI differ, and identify key use cases, target audiences, system
    components, and the types of supported queries and responses. Furthermore, we
    investigate the current paradigms by which systems are evaluated and highlight
    their key limitations. Key findings include identifying the main use cases, objectives,
    and audiences targeted by dialogue-based XAI methods, and summarize the main types
    of questions and information needs. Beyond discussing avenues for future work,
    we present a meta-architecture for these systems from existing literature and
    outlined prevalent theoretical frameworks.
