  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.

  text: In-situ computed tomography (CT) experiments on materials with time-dependent
    mechanical behaviour are affected by relaxationinduced motion, which can lead
    to image blur and motion-related artefacts if scans are initiated before relaxation-induced
    motion has subsided. Scan start times are therefore commonly defined based on
    force relaxation or force-gradient criteria, although these signals do not directly
    quantify image-relevant specimen motion. In this work, a radiography-based approach
    is presented to estimate relaxation-induced motion via pixel shifts from projection
    images acquired prior to CT scans. These projection-based pixel shift estimates
    of relaxation-induced motion are related to scan-specific image blur observed
    in the reconstructed volumes. Thereby, a direct link between specimen motion during
    the scan and CT image quality is established. The method is demonstrated for thermo-mechanically
    loaded specimens with pronounced temperature-dependent material behaviour, where
    relaxation-induced motion persists over extended time scales. The results show
    that projection-based pixel shift estimation provides a physically meaningful
    and experimentally accessible basis for defining scan start criteria. CT acquisition
    can be initiated based on an allowable level of relaxation-induced motion, rather
    than waiting for mechanical equilibrium to be reached. The proposed approach therefore
    offers a direct, image-related framework for scan timing in in-situ CT experiments
    on time-dependent materials.</jats:p>

  text: <jats:p>Clinched joints with non-rotationally symmetric geometries exhibit
    orientation-dependent mechanical behavior that is commonly neglected in structural-scale
    simulations. Reuleaux triangle shaped clinched joints, in particular, show pronounced
    in-plane anisotropy depending on their orientation. While such effects have been
    studied at joint and specimen scale, their relevance at the structural level remains
    largely unexplored. In this work, the influence of joint orientation on the bending
    response of a joined structure is investigated using numerical simulations. A
    simplified joint replacement model based on the *CONSTRAINED_SPR2 point-connector
    formulation in LS-DYNA is employed, with parameters calibrated from previously
    obtained experimental force displacement data. A hat shaped profile structure
    subjected to three-point bending is analyzed in a parametric study considering
    variations in joint orientation, joint spacing, and profile geometry. The results
    show that joint orientation has little influence during the initial deformation
    phase but becomes increasingly significant at larger displacements, where joint
    behavior governs load transfer. Orientation dependent effects are found to influence
    the global force displacement response and local load redistribution among joints,
    with magnitudes comparable to those induced by changes in joint spacing and structural
    geometry. The findings confirm that joint orientation effects remain relevant
    at the structural level and should be considered in the design of structures assembled
    using non-rotationally symmetric clinched joints.</jats:p>

  text: <jats:p>Lehrer:innen nutzen und veröffentlichen Unterrichtsmaterial auf verschiedenen
    Plattformen. Da diese Materialien, anders als Schulbücher, kein Qualitätssicherungsverfahren
    durchlaufen, wird aktuell die Frage nach der Verantwortung für die Qualitätssicherung
    dieses Materials diskutiert. Abbildungen von Menschen im Unterrichtsmaterial transportieren
    soziokulturelle und pädagogische Inhalte, die eine kritische Prüfung erfordern.
    Dieser Beitrag adressiert die Frage, welche Differenzkonstruktionen und Stereotypisierungen
    im Bildmaterial von digital verfügbarem Unterrichtsmaterial vorhanden sind. Verwendet
    wurde ein Materialkorpus drei verschiedener Plattformen mit Unterrichtsmaterialien
    der Sekundarstufe 1 (5. – 10. Klasse) mit 329 Bildern von Menschen (Zeichnungen
    und Fotografien). Dieser wurde analysiert in Bezug auf die deskriptive Häufigkeit
    der Darstellung bestimmter Personengruppen sowie qualitativ und intersektional
    mit der hermeneutischen Sequenzanalyse. Zentrale Ergebnisse sind, dass vor allem
    Personen dargestellt werden, die in maximal einer Dimension von der weissen, heterosexuellen,
    nicht behinderten Norm abweichen. Darstellungen von sichtbaren Behinderungen und
    People of Color (BIPoC) kommen kaum vor. Diversität wird vereinzelt in Gruppenbildern
    dargestellt, jedoch nicht in Familienbildern. Othering und negative emotionale
    Konnotationen sind in den Darstellungen erkennbar, wenn z. B. Schwarzsein als
    Abweichung von der Norm verstanden wird, Körperproportionen verzerrt oder Sportler:innen
    als unsicher dargestellt werden. Die Analyse von digital bereitgestelltem Unterrichtsmaterial
    macht deutlich, dass ähnliche Problematiken zu beobachten sind, wie sie durch
    die Schulbuchforschung für Schulbücher beschrieben werden.</jats:p>

  text: Self-piercing riveting (SPR) is a well-established joining technique in lightweight
    construction, as it enables the joining of different materials without requiring
    pre-drilling. However, the necessary adaptation of the rivet-die combination to
    the respective material and thickness combinations requires a large number of
    specific tool sets, which significantly limits the process's flexibility. To overcome
    these limitations, the versatile self-piercing riveting (V-SPR) was developed,
    which features enhanced punch actuation in combination with a multi-range-capable
    rivet . In this context, the concept of a movable die was introduced, which enables
    an extended process window and adaptable joint formation. Kappe et al. presented
    initial studies demonstrating the potential of this approach . However, a detailed
    numerical understanding of the underlying mechanisms remains lacking. This paper
    presents a numerical analysis of V-SPR with a movable die using a finite element
    (FE) model. The model includes deformable rivets, sheet metal materials and a
    kinematically controlled die with adjustable movement. A parameter study was conducted
    to analyse the influence of die movement on the material flow of the rivet and
    sheets, as well as joint formation. The simulations were validated using selected
    experimental data. The goal is to compare the joint geometries achieved with fixed
    and moving dies and expand the process windows of VSPR. The results demonstrate
    that the movable-die concept significantly enhances the material flow of both
    the sheets and the rivet, resulting in a noticeably larger and more reliable interlock
    than what is achievable with V-SPR using a fixed die. The numerical analyses support
    the observations reported by Kappe et al. and extend them by providing a quantitative
    description of how die displacement influences the resulting interlock size. Moreover,
    the ability to precisely control the die movement makes it possible to join challenging
    sheet-metal combinations that are difficult to process with conventional setups,
    particularly in cases involving thicker sheet materials.

  text: "Das hochschuldidaktische Konzept des Forschenden Lernens gilt als zentrales
    Element der universitären Lehrkräftebildung in Deutschland und ist in fast allen
    Bundesländern Bestandteil des Praxissemesters. Damit einhergehende Erwartungen
    im Hinblick auf den Professionalisierungsprozess von Lehrkräften fokussieren insbesondere
    die Vermittlung einer forschenden Grundhaltung, die auf eine nicht-wissenschaftsferne
    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.</jats:p>\r\n
    \         <jats:p>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."

  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>The design
    of clinch joints is a cost- and time-intensive iterative process due to the complex
    relationships between tool and process parameters and the resulting joint properties.
    To address this, this contribution proposes a novel hybrid workflow that combines
    knowledge- and data-based approaches. Relationships are categorized based on their
    knowledge quality and the need for a quantitative prediction. Well-established,
    generalizable relationships are formalized in an ontology as design guidelines
    (no quantification required) or SWRL rules (quantification required) to model
    expert knowledge. In contrast, hard-to-formalize or not-fully-understood relationships
    are treated with regression models for continuous or classification models for
    binary criteria. These approaches are combined in a generic user interface (GUI),
    where the ontology can be accessed using predefined SPARQL queries to select and
    adapt parameters using expert knowledge. These parameters are then used as input
    for the metamodels. The developed workflow is evaluated on two exemplary joining
    tasks to illustrate, how designers can retrieve similar prior joints, adapt parameters
    using the encoded design rules and predict resulting joint properties under varying
    process conditions. In summary, the combination of ontology and metamodels facilitates
    the transition of trial and error into an efficient, documentable design process.</jats:p>"

  text: Sound capture by microphone arrays opens the possibility to exploit spatial,
    in addition to spectral, information for diarization and signal enhancement, two
    important tasks in meeting transcription. However, there is no one-to-one mapping
    of positions in space to speakers if speakers move. Here, we address this by proposing
    a novel joint spatial and spectral mixture model, whose two submodels are loosely
    coupled by modeling the relationship between speaker and position index probabilistically.
    Thus, spatial and spectral information can be jointly exploited, while at the

  text: '**ABSTRACT**<br> <p>While studying abroad, international students not only
    pursue academic qualifications but also begin to imagine and plan their future
    mobility trajectories. One central decision concern is whether to remain in the
    host country after graduation or return to the country of origin or move to another
    country. This article investigates the individual and social factors that shape
    post‐graduation work intentions among international Chinese students in Germany,
    the second‐largest international student group in the country. Drawing on original
    survey data from the Bright Futures project (2018), we analyse how life satisfaction,
    romantic partnerships, career aspirations and social networks influence students’
    likelihood of planning to work in Germany after graduation. Using binary logistic
    regression models, we find that higher life satisfaction, valuing meaningful employment
    and having a partner in Germany are all significantly associated with intentions
    to stay. In contrast, the geographical location of broader personal networks shows
    no significant effect. These findings contribute to migration and higher education
    research by foregrounding the role of subjective well‐being and certain forms
    of relational embeddedness in shaping students’ imagined futures. Rather than
    treating international students as passive participants in education‐driven mobility,
    we highlight how personal and emotional factors influence their transition into
    potential long‐term migrants.</p>'

  text: "The theory of Total Function NP (TFNP) and its subclasses says that, even
    if\r\none is promised an efficiently verifiable proof exists for a problem, finding\r\nthis
    proof can be intractable. Despite the success of the theory at showing\r\nintractability
    of problems such as computing Brouwer fixed points and Nash\r\nequilibria, subclasses
    of TFNP remain arguably few and far between. In this\r\nwork, we define two new
    subclasses of TFNP borne of the study of complex\r\npolynomial systems: Multi-homogeneous
    Systems (MHS) and Sparse Fundamental\r\nTheorem of Algebra (SFTA). The first of
    these is based on B\\'ezout's theorem\r\nfrom algebraic geometry, marking the
    first TFNP subclass based on an algebraic\r\ngeometric principle. At the heart
    of our study is the computational problem\r\nknown as Quantum SAT (QSAT) with
    a System of Distinct Representatives (SDR),\r\nfirst studied by [Laumann, L\\\"auchli,
    Moessner, Scardicchio, and Sondhi 2010].\r\nAmong other results, we show that
    QSAT with SDR is MHS-complete, thus giving\r\nnot only the first link between
    quantum complexity theory and TFNP, but also\r\nthe first TFNP problem whose classical
    variant (SAT with SDR) is easy but whose\r\nquantum variant is hard. We also show
    how to embed the roots of a sparse,\r\nhigh-degree, univariate polynomial into
    QSAT with SDR, obtaining that SFTA is\r\ncontained in a zero-error version of
    MHS. We conjecture this construction also\r\nworks in the low-error setting, which
    would imply SFTA is contained in MHS."

  text: "Classical shadows are succinct classical representations of quantum states\r\nwhich
    allow one to encode a set of properties P of a quantum state rho, while\r\nonly
    requiring measurements on logarithmically many copies of rho in the size\r\nof
    P. In this work, we initiate the study of verification of classical shadows,\r\ndenoted
    classical shadow validity (CSV), from the perspective of computational\r\ncomplexity,
    which asks: Given a classical shadow S, how hard is it to verify\r\nthat S predicts
    the measurement statistics of a quantum state? We show that\r\neven for the elegantly
    simple classical shadow protocol of [Huang, Kueng,\r\nPreskill, Nature Physics
    2020] utilizing local Clifford measurements, CSV is\r\nQMA-complete. This hardness
    continues to hold for the high-dimensional\r\nextension of said protocol due to
    [Mao, Yi, and Zhu, PRL 2025]. Among other\r\nresults, we also show that CSV for
    exponentially many observables is complete\r\nfor a quantum generalization of
    the second level of the polynomial hierarchy,\r\nyielding the first natural complete
    problem for such a class."
