  text: <jats:p>The mechanical joining of continuous fiber-reinforced thermoplastics
    (cFRTP) and metal sheets represents a promising approach for manufacturing hybrid
    lightweight structures. To reduce the time and cost associated with extensive
    experimental investigations, numerical modeling strategies are increasingly applied.
    In this numerical study, a further step in the modelling strategy for the direct
    pin-pressing (DPP) process of cFRTP and metal sheets is presented. The study focuses
    on modeling and simulating the occurring deformation mechanisms of decomposition,
    compaction, and separation of individual rovings on the mesoscale to analyze the
    resulting material structure. For this purpose, two simplified models were derived.
    The textile architecture is represented based on micrographs of cross-sections
    and discretized using the finite element method. The deformation of individual
    rovings during joining leads to a deformation of their initial elliptical cross
    section. To capture this level of resolution, both a cohesive zone and a pure
    contact approach are applied within the rovings. The highly viscous thermoplastic
    melt is modeled as a fluid employing the Arbitrary Lagrange–Eulerian (ALE) method.
    Matrix and roving meshes are coupled to account for fluid–structure interaction
    (FSI) during process. The study shows that coupling of matrix and rovings is necessary
    to obtain more accurate predictions of the deformation behaviour. Furthermore,
    the cohesive zone approach is better suited to simulate the emerging deformation
    mechanisms.</jats:p>

  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.</jats:p>'

  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.

  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>
