  text: "<jats:p>\r\n                    In this study, we investigate the impact
    of chromium-induced point defects on the nonlinear optical properties and electric-field-induced
    second harmonic generation (EFISH) in rutile titanium dioxide (TiO\r\n                    <jats:sub>2</jats:sub>\r\n
    \                   ). Chromium thin films were deposited by electron beam evaporation
    on (001)-oriented bulk TiO\r\n                    <jats:sub>2</jats:sub>\r\n                    substrates
    and subsequently diffused into the lattice in a tube furnace under a nitrogen
    atmosphere at 900 °C. The introduction of chromium significantly enhanced the
    third harmonic generation (THG) of a 1560 nm laser, with an amplification factor
    of up to 8.3, indicative of an enhanced third-order nonlinear susceptibility,\r\n

    \                   . Moreover, the application of an external voltage induced
    a pronounced EFISH signal in the chromium-doped samples, further confirming the
    enhanced nonlinear response. These results demonstrate that defect engineering

    \                   offers a promising pathway for the development of high-performance
    nonlinear optical devices.\r\n                  </jats:p>"

  text: This paper investigates two modeling approaches for the simulation of the
    deformation and decomposition behavior of preconsolidated rovings above the thermoplastic
    matrix{\textquoteright} melting temperature. This is crucial for capturing the
    local material structure after processes introducing highly localized deformation
    such as mechanical joining processes between metal and fiber reinforced thermoplastics
    (FRTP). A generic finite element (FE) model is developed, incorporating interfaces
    discretized through either cohesive zone (CZ) elements or Coulomb friction-based
    contacts. The material parameters for the FE elements are derived from the initial
    stiffness of a statistical volume element (SVE) at micro scale modelled with an
    Arbitrary-Lagrange-Eulerian method for three load cases. The CZ properties calculated
    are based on the shear viscosity of the composite. The CZ and contact modelling
    approaches are evaluated using three load cases of the SVE, comparing force-displacement
    curves. Under simple loading conditions, such as normal pressure tension and bending,
    both methods produce similar results; however, in complex load cases, the CZ approach
    shows clear advantages in handling interface interactions and shows robust simulations.
    The CZ approach thus presents a promising method for simulating roving decomposition
    in FRTP-metal joining applications above the matrix{\textquoteright} melting temperature.

  text: The failure behavior of fiber reinforced polymers (FRP) is strongly influenced
    by their microstructure, i.e. fiber arrangement or local fiber volume content.
    However, this information cannot be directly used for structural analyses, since
    it requires a discretization on micrometer level. Therefore, current failure theories
    do not directly account for such effects, but describe the behavior averaged over
    an entire specimen. This foundation in experimentally accessible loading conditions
    leads to purely theory based extension to more complex stress states without direct
    validation possibilities. This work aims at leveraging micro-scale simulations
    to obtain failure information under arbitrary loading conditions. The results
    are propagated to the meso-scale, enabling efficient structural analyses, by means
    of machine learning (ML). It is shown that the ML model is capable of correctly
    assessing previously unseen stress states and therefore poses an efficient tool
    of exploiting information from the micro-scale in larger simulations.

  text: The use of continuous fiber-reinforced thermoplastics (FRTP) in automotive
    industry increases due to their excellent material properties and possibility
    of rapid processing. The scale spanning heterogeneity of their material structure
    and its influence on the material behavior, however, presents significant challenges
    for most joining technologies, such as self-piercing riveting (SPR). During mechanical
    joining, the material structure is significantly altered within and around the
    joining zone, heavily influencing the material behavior. A comprehensive understanding
    of the underlying phenomena of material alteration during the SPR process is essential
    as basis for validating numerical simulations. This study examines the material
    structure at ten stages of a step-setting test of SPR with two FRTP sheets with
    glass-fiber reinforcement. Utilizing X-ray computed tomography (CT), the damage
    phenomena within different areas of the setting test are analyzed three-dimensionally
    and key parameters are quantified. Dominating phenomena during the penetration
    of the rivet into the laminate are fiber failure (FF), interfiber failure (IFF)
    and fiber bending, while delamination, fiber kinking and roving splitting are
    also observed. At the final stages, the bottom layers of the second sheet collapse
    and form a bulge into the cavity of the die.

  text: '<jats:p>Abstract. Accurate Finite Element Modeling (FEM) of joints is essential
    in the design of complex mechanical systems such as automotive body-in-white (BIW)
    structures, as it plays a critical role in evaluating their performance. Although
    well-established techniques exist for modeling rotationally symmetric joints,
    there remains a significant gap in effectively modeling non-rotationally symmetric
    joints. These joints are particularly relevant in the automotive BIW, where they
    can better accommodate anisotropic loading conditions. In this study, strategies
    for modeling non-rotationally symmetric joints were explored using finite element
    simulations in LS-DYNA. The findings demonstrate that discrete beam elements can
    capture the anisotropic characteristics of such joints. Two models were tested:
    a single-beam model for stiffness periodicity every 90°, and a three-beam model
    for stiffness periodicity every 120°. Force responses, stress distribution, and
    sheet bending behaviors were analyzed, confirming that discrete beam elements
    can accurately represent direction-dependent stiffness. These results establish
    a foundation for developing advanced joint modeling strategies in complex mechanical
    systems.</jats:p>'

  text: This study proposes a fault diagnostics methodology that addresses the challenges
    posed by highly imbalanced datasets typical of railway applications, where faulty
    conditions constitute the minority class. Fault diagnostics is performed from
    the component level upward, considering each sensor’s proximity to its respective
    critical component. Advanced signal analysis, feature engineering, and automated
    data-driven model generation techniques were explored to achieve comprehensive
    diagnostics, such that the model development process accounts for variations in
    the operating conditions and differing levels of information availability. The
    proposed methodology is evaluated on datasets from the MONOCAB, for scenarios
    with limited faulty instances and on the Beijing 2024 IEEE PHM Conference data
    challenge, which focused on fault diagnostics of railway systems under various
    fault modes and operating conditions.

  text: The article explores the role of teachers in self-directed songwriting in
    school music based on the informal learning approach. It investigates a didactic
    design that was implemented in six schools and was empirically researched utilizing
    si-tuational analysis. Based on tensions, that emerge due to conflicting expectations,
    it can be shown, that the teacher's role extends beyond the dichotomy of directive
    instruction versus open facilitation. Instead, it encompasses an interplay of
    six divergent roles which are discussed in their positions in relation to each
    other. These considerations enrich the understanding of teaching practices in
    popular music education, emphasizing the redefinition of teacher-student relationships
    for song-writing in school music.

  text: The role of institutionalized standards for the hybridization of musical practices.
    On the socio-materiality of songwriting-producing in the bedroom studio This study
    examines the socio-materiality of hybrid music practices in bedroom studios, focusing
    on the interplay between traditional music education institutions and YouTube
    education. A single case situational analysis reveals how standardized instrumental
    and music production practices are combined to form a hybrid practice. It shows
    that traditional music education institutions, such as music schools and conservatories,
    specialize in the selection of chord tones, while You-Tube videos focus on sound
    design. Using an actor-network theory approach, the study demonstrates the permeability
    of informal and institutional learning spaces. The findings suggest that songwriting-producing
    is not simply a sum of different practices, but rather a process of negotiation
    and compromise between different standards and goals, as well as the distribution
    of practice between humans and technology.
