  text: <jats:p>Diffractive neural networks (DNNs) are an emerging approach for the
    realization of photonic artificial intelligence, especially due to their suitability
    for machine-vision applications and high-dimensional photonic information processing
    at lower power consumption. However, incorporating optical nonlinear activation
    functions to make DNNs a feasible alternative to their electronic counterpart
    remains a challenge. Here, we investigate the inclusion of second-harmonic generation
    (SHG), as one of the simplest and most efficient types of optical nonlinearities,
    in DNNs. We numerically investigate the impact of SHG on the performance of classification
    tasks in an all-optical nonlinear DNN. Specifically, we investigate and discuss
    the essential requirements for an effective arrangement of a SHG activation in
    single and multilayer DNNs. We find that the performance, in terms of classification
    accuracy and class contrast, is affected strongly by the positioning of the SHG
    activation. Finally, we discuss and outline the constraints for including SHG
    in an experimental realization. Taking these constraints into account, we estimate
    the power-related efficiency of the nonlinear DNN system. Overall, our results
    provide a path towards implementing nonlinear DNNs using the SHG process.</jats:p>

  text: <jats:p>We investigated the spectral properties of squeezed light generated
    via parametric down-conversion in the high-gain regime, considering both unapodized
    and apodized dispersion-engineered waveguides. The gain-dependent evolution of
    these states is examined starting from the low-gain regime, which includes both
    highly correlated and nearly uncorrelated cases. For the unapodized configuration,
    our simulated results show a monotonic increase in spectral purity with gain,
    whereas for some of the apodized configuration, they exhibit a nonmonotonic dependence,
    initially decreasing and then recovering at higher gain. By combining Schmidt-mode
    analysis with a group-velocity-based interpretation, we explain why different
    dispersion conditions exhibit distinct gain-dependent behavior, specifically that
    rapid purification occurs when the pump group velocity lies between those of the
    signal and idler. Our study shows that the evolution of spectral purity is governed
    primarily by the underlying dispersion of the waveguide. These results demonstrate
    that dispersion engineering and parametric gain can be jointly exploited to tailor
    the spectral-mode structure of squeezed-light sources, enabling their optimization
    for a broad range of quantum applications.</jats:p>

  text: Laser Powder Bed Fusion (PBF-LB/M) enables significant performance enhancements
    in tool and mold making via the integration of complex, conformal cooling channels.
    However, high manufacturing costs of monolithic components and material-specific
    defect susceptibility still hinder widespread industrial adoption. Within the
    collaborative project WerKo3D, the scaling, process qualification, and structural
    design of the novel tool steel Printium 13 were successfully investigated to lower
    market entry barriers for additive tooling applications. An industrial batch of
    50 kg of Printium 13 powder was produced via vacuum inert gas atomization and
    thoroughly characterized. Utilizing a Design of Experiments (DoE) approach on
    an SLM 280 system, an optimized process window was established, yielding a relative
    density of about 99.99%. Subsequent heat treatment parameterizations revealed
    a superior mechanical property profile combining high hardness with enhanced impact
    toughness compared to conventional AISI H13 tool steel, alongside ultimate tensile
    strengths up to 1,600 MPa. To reduce build times and material consumption, a segmented
    shell-core tool design was conceptualized and numerically optimized via coupled
    CFD and FEM simulations. The functional demonstrator - a sprue insert for aluminum
    die casting - was additively manufactured without cracking, heat-treated, and
    finish-machined to final dimensions. Furthermore, a two-day training and knowledge-transfer
    program was realized to disseminate design guidelines to industry stakeholders.
    The findings validate the complete process chain from powder atomization to crack-free
    hybrid tool manufacturing.

    probing of strong-field electron dynamics in condensed matter and the development

    high-order harmonics, which are usually interpreted through short electron-hole
    trajectories that recombine within one optical cycle, the microscopic origin of
    low-order emission near the bandgap remains poorly understood. Here, we investigate
    near-bandgap harmonic generation in ZnO by combining semiconductor Bloch equations with
    a complex-time quantum-trajectory analysis. Our results indicate that these harmonics
    are not a continuation of the short trajectory. Rather, they originate from multiple-scattering
    trajectories, in which the electron-hole pair undergoes repeated Bragg scattering

  text: "We introduce the non-symmetric heat and Poisson semigroups associated with
    the Heckman-Opdam Laplacian in the compact setting. Based on the Poisson semigroup,
    we study several Littlewood-Paley $g$-functions in the spirit of Stein's work
    for compact Lie groups and prove their $L^{p}$-boundedness for $1<p<\\infty$.
    As an application, we define associated Riesz transforms and Riesz potentials
    and prove their $L^{p}$-continuity for $1<p<\\infty$. \r\n  Passing to the average
    with respect to the action of the associated reflection group, our framework in
    particular covers the Littlewood-Paley-Stein theory for Jacobi polynomial expansions
    and corresponding direct product settings as special cases."

  text: For an arbitrary reduced root system, we give upper bounds for the Dunkl kernel
    with regular spectral parameter and its derivatives, which are uniform in the
    spatial variable. These estimates generalize well-known sharp upper bounds for
    classical one-variable Bessel functions and for spherical functions of Cartan
    motion groups. As a consequence, we prove that the representing measure of Dunkl's
    intertwining operator is absolutely continuous with respect to the Lebesgue measure
    for multiplicities $k> 1/2$ and generic spectral parameter. This settles a conjecture
    posed in [RdJ02] at least for $k>1/2$.

  text: Approval of products in safety-sensitive areas, such as medical technology,
    requires considerable effort. Companies must comply with numerous regulations
    for such product approvals. This results in requirements for processes, methods,
    tools and organizations throughout the product life cycle. A proven approach to
    handling regulatory requirements is the application of product lifecycle management
    (PLM) platforms. Applying PLM platforms (e.g. Teamcenter, 3DExperience) poses
    challenges in designing compliant processes as well as adapting methods and tools.
    For example, in medical technology, ISO 13485 specifies an industry-specific product
    engineering process. The exemplary adaptations of requirements engineering methods
    and related support – e.g. MBSE including Requirements Diagrams – are not intuitively
    apparent. Existing literature primarily regards these regulation-related challenges
    as boundary conditions, offering only vague operational solutions. Companies struggle
    to align PLM processes with regulatory requirements, yet few methods exist to
    support this integration. In this paper, a method is proposed that supports the
    application of regulation-centered PLM platforms and reduces effort in product
    approvals. The method is developed by applying a five-step approach. Existing
    literature on process models for applying PLM platforms is identified (1). The
    identified approaches are then analyzed to determine whether and to what extent
    they consider regulations in applying PLM platforms (2). Based on identified partial
    solutions from literature and findings from industry workshops, a new method is
    developed (3). The method comprises strategic level, process level, data level,
    pilot level, and operation level. Validation is conducted within a German medical
    technology company, containing proof of applicability determined through a pilot
    project (4) and proof of concept achieved through interviews (5). The method is
    applied to regulation-centered PLM for the use case ‘requirements engineering’.
    The concept is confirmed by experts in terms of applicability and transferability.
    The method supports engineers in applying regulation-centered PLM platforms, leading
    to reduced effort.

  text: "<jats:p>\r\n                    We develop a framework for identifying nonclassical
    speedups in systems with polarization, likewise spin degrees of freedom. By confining
    the dynamics to the manifold of angular momentum coherent states, which act as
    the classical reference in this case, we compute the speed limit that bounds the
    rate of change of the state achievable without generating quantum coherence. A
    comparison with the unrestricted quantum speed limit enables the quantitative
    identification of speedups arising from polarization nonclassicality. We apply
    this framework to the cross-Kerr interaction, demonstrating a persistent speedup
    scaling as\r\n                    <a:math xmlns:a=\"http://www.w3.org/1998/Math/MathML\">\r\n

  text: Friction spinning is a metal forming process that can be used to manufacture
    various shapes by rotating a metallic workpiece relative to a blunt tool. When
    used as a hot metal forming process, the relative velocity between workpiece and
    tool is increased until substantial heat is generated due to friction. This frictional
    heat softens the workpiece and allows it to be more readily shaped. However, the
    process's complex interactions between mechanical, frictional and thermal effects
    pose significant challenges for numerical modelling. The present study outlines
    a numerical model that uses the arbitrary Lagrangian–Eulerian (ALE) formulation
    in a rotating frame to simulate the friction spinning process. The key enabler
    is an incremental ALE formulation with reference‐velocity‐based remapping that
    allows for severe deformation and large rotational motion while preserving path‐dependent
    constitutive history variables. Proof‐of‐concept examples demonstrate its ability
    to simulate the upsetting of rods and rivets by friction spinning. The potential
    of the ALE formulation for modelling friction spinning is thereby confirmed, which
    paves the way for further research, model enhancements, parameter identifications
    and applications.
