  text: Background. Clinching is a conventional cold forming process in which two
    or more sheets can be joined without auxiliary parts. A pre-forming of the parts
    to be joined, which is introduced by previous manufacturing steps, has an influence
    on the joining result. When considering the suitability for joining with regard
    to the formability of the materials, the influence of the preforming steps must
    be taken into account. The influences of strain hardening and sheet thickness
    on the joining properties must be investigated. In this context, a Finite Element
    Method (FEM) based metamodel analysis of the clinching process was carried out
    in [1] to investigate the robustness of the clinching process with respect to
    the different material pre-strains. In [2], the method was extended to the load
    bearing simulation.Procedure. The metamodel from preliminary work based on various
    FE models, which predicts the load-bearing capacity of a clinched joint influenced
    by pre-straining, is compared here with experimental data and the accuracy of
    the metamodel prediction is discussed. For this purpose an experimental procedure
    was further develop which allows the preforming of metal sheets from which joining
    specimens can be separated with a certain degree of unidirectional deformation.
    In the study, the procedure for preparing the joint specimens and the results
    of the loading tests are presented. Different possible relevant pre-strain combinations
    are investigated and compared with the simulation results, to validate the FE
    models and choose suitable metamodel.</jats:p>

  text: '<jats:p>How can Knowledge In/Equity be addressed in qualitative research
    by taking the idea of Open Science into account? Two projects from the Open Science
    Fellows Programme by Wikimedia Deutschland will be used to illustrate how Open
    Science practices can succeed in qualitative research, thereby reducing In/Equity.
    In this context, In/Equity is considered as a fair and equal representation of
    people, their knowledge and insights and comprehends questions about how epistemic,
    structural, institutional and personal biases generate and shape knowledge as
    guidance. Three questions guide this approach: firstly, what do we understand
    by In/Equity in the context of knowledge production in these projects? Secondly,
    who will be involved in knowledge generation and to what extent will they be valued
    or unvalued? Thirdly, how can data be made accessible for re-use to enable true
    participation and sharing?</jats:p>'

  text: Der Beitrag beschäftigt sich mit dem Gebrauch von sogenannten Open Educational
    Resources (OER) innerhalb der deutschsprachigen Soziologie. OER sind Lehr-und
    Lernmaterialien, die öffent-lich und frei von Kosten zugänglich sind sowie unter
    einer offenen Lizenz stehen, die es erlaubt, das Material frei zu nutzen, zu vervielfältigen
    und zu bearbeiten. Um diese Form der Bereitstellung von Lehr-und Lernmaterial
    zu fördern, sind im deutschen Sprachraum in den letzten Jahren verschie-dene digitale
    Infrastrukturen entstanden, die an einzelnen Hochschulstandorten, aber auch hochschulübergreifend
    Lehrenden zur Verfügung stehen, um dort ihr Material zu veröffentlichen. Es wurden
    37 dieser Repositorien untersucht. Darüber hinaus wurde auch die Videoplattform
    YouTube nach soziologischem Lehr-und Lernmaterial durchforstet. Der Beitrag stellt
    den Zeitverlauf und die Akteur:innen der OER-Veröffentlichungen dar. Anschließend
    soll mithilfe eines praxistheoretischen Vokabulars die Lehre innerhalb der Soziologie
    aufgeschlüsselt und ein möglicher Bezug zu den empirischen Ergebnissen hergestellt
    werden.

  text: Recent analyses by polarization resolved second-harmonic (SH) microscopy have
    demonstrated that ferroelectric (FE) domain walls (DWs) can possess non-Ising
    wall characteristics and topological nature. These analyses rely on locally analyzing
    the properties, directionality, and magnitude of the second-order nonlinear tensor.
    However, when inspecting FE DWs with SH microscopy, a manifold of different effects
    may contribute to the observed signal difference between domains and DWs, i.e.,
    far-field interference, Čerenkov-type phase-matching (CSHG), and changes in the
    aforementioned local nonlinear optical properties. They all might be present at
    the same time and, therefore, require careful interpretation and separation. In
    this work, we demonstrate how the particularly strong Čerenkov-type contrast can
    selectively be blocked using dark- and bright-field SH microscopy. Based on this
    approach, we show that other contrast mechanisms emerge that were previously overlayed
    by CSHG but can now be readily selected through the appropriate experimental geometry.
    Using the methods presented, we show that the strength of the CSHG contrast compared
    to the other mechanisms is approximately 22 times higher. This work lays the foundation
    for the in-depth analysis of FE DW topologies by SH microscopy.

  text: Spontaneous Raman spectroscopy (SR) is a versatile method for analysis and
    visualization of ferroelectric crystal structures, including domain walls. Nevertheless,
    the necessary acquisition time makes SR impractical for in situ analysis and large
    scale imaging. In this work, we introduce broadband coherent anti-Stokes Raman
    spectroscopy (B-CARS) as a high-speed alternative to conventional Raman techniques
    and demonstrate its benefits for ferroelectric domain wall analysis. Using the
    example of poled lithium niobate, we compare the spectral output of both techniques
    in terms of domain wall signatures and imaging capabilities. We extract the Raman-like
    resonant part of the coherent anti-Stokes signal via a Kramers–Kronig-based phase
    retrieval algorithm and compare the raw and phase-retrieved signals to SR characteristics.
    Finally, we propose a mechanism for the observed domain wall signal strength that
    resembles a Čerenkov-like behavior, in close analogy to domain wall signatures
    obtained by second-harmonic generation imaging. We, thus, lay here the foundations
    for future investigations on other poled ferroelectric crystals using B-CARS.

  text: Conductive domain walls (DWs) in insulating ferroelectrics have recently attracted
    considerable attention due to their unique topological, optical, and electronic
    properties, and offer potential applications such as in memory devices or rewritable
    circuitry. The electronic properties of DWs can be tuned by the application of
    strain, hence controlling the charge carrier density at DWs. In this paper, we
    study the influence of uniaxial stress on the conductivity of DWs in the bulk
    single crystal lithium niobate (LiNbO3). Using conductive atomic force microscopy,
    we observe a large asymmetry in the conductivity of DWs, where only negatively
    screened walls, so called head-to-head DWs, are becoming increasingly conductive,
    while positively screened, tail-to-tails DWs, show a decrease in conductivity.
    This asymmetry of DW conductivity agrees with our theoretical model based on the
    piezoelectric effect. In addition, we observed that the current in the DW increases
    up to an order of magnitude for smaller compressive stresses of 100 MPa. This
    response of DWs remained intact for multiple stress cycles over two months, opening
    a path for future applications.

  text: Strongly charged head-to-head domain walls that are purposely engineered along
    the [110] crystallographic orientation into ferroelectric BaTiO3 single crystals
    have been proposed as intrinsically nanoscaled two-dimensional electron gases
    (2DEGs) because of their significant conductivity. Here, we quantify these 2DEG
    properties through dedicated Hall transport measurements in van der Pauw 4-point
    geometry, finding the electron mobility to reach around 400 cm2 (V s)^{−1}, while
    the two-dimensional charge density amounts to 7 × 103 cm^{–2}. We underline the
    necessity to take into account the thermal and geometrical misalignment offset
    voltages by evaluating the Hall resistance under magnetic field sweeps; otherwise,
    errors of several hundred percent in the derived transport parameters can occur.

    stacking order, symmetry, or electronic and vibrational properties. Thin films
    and 2D materials are usually supported on multi-layered substrates leading to
    (multi-)reflections, interference, or phase jumps at interfaces during μ-spectroscopy,
    which all can make the interpretation of experiments particularly challenging.
    The disentanglement of the influence parameters can be achieved via rigorous theoretical
    analysis. In this work, we compare two self-developed modeling approaches, a semi-analytical
    and a fully vectorial model, to experiments carried out in thin-film geometry
    for two archetypal NLO processes, second-harmonic and third-harmonic generation.
    In particular, we demonstrate that thin-film interference and phase matching do
    heavily influence the signal strength. Furthermore, we work out key differences
    between three and four photon processes, such as the role of the Gouy-phase shift
    and the focal position. Last, we can show that a relatively simple semi-analytical
    model, despite its limitations, is able to accurately describe experiments at
    a significantly lower computational cost as compared to a full vectorial modeling.
    This study lays the groundwork for performing quantitative NLO μ-spectroscopy
    on thin films and 2D materials, as it identifies and quantifies the impact of
    the corresponding sample and setup parameters on the NLO signal, in order to distinguish
    them from genuine material properties.<

  text: Second harmonic (SH) microscopy represents a powerful tool for the investigation
    of crystalline systems, such as ferroelectrics and their domain walls (DWs). Under
    the condition of normal dispersion, i.e., the refractive index at the SH wavelength
    is larger as compared to the refractive index at the fundamental wavelength, n(2ω)>n(ω),
    bulk crystals will generate no SH signal. Should the bulk, however, contain DWs,
    an appreciable SH signal will still be detectable at the location of DWs stemming
    from the Čerenkov mechanism. In this work, we demonstrate both how SH signals
    are generated in bulk media and how the Čerenkov mechanism can be inhibited by
    using anomalous dispersion, i.e., n(ω)<n(2ω). This allows us to quantitatively
    estimate the relative strength of the Čerenkov compared to other SH contrast mechanisms
    in DWs, such as the interference contrast. The results are in agreement with previous
    experiments based on the geometric separation of the signals. Due to the observed,
    strong Čerenkov contrast, such signal contributions may not be neglected in polarimetry
    studies of ferroelectric DWs in the future.

  text: "The intelligibility of demodulated audio signals from analog high frequency
    transmissions, e.g., using single-sideband\r\n(SSB) modulation, can be severely
    degraded by channel distortions and/or a mismatch between modulation and demodulation
    carrier frequency. In this work a neural network (NN)-based approach for carrier
    frequency offset (CFO) estimation from demodulated SSB signals is proposed, whereby
    a task specific architecture is presented. Additionally, a simulation framework
    for SSB signals is introduced and utilized for training the NNs. The CFO estimator
    is combined with a speech enhancement network to investigate its influence on
    the enhancement performance. The NN-based system is compared to a recently proposed
    pitch tracking based approach on publicly available data from real high frequency
    transmissions. Experiments show that the NN exhibits good CFO estimation properties
    and results in significant improvements in speech intelligibility, especially
    when combined with a noise reduction network."
