  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>We present
    a novel algorithm for quantization and subsequent hexahedral mesh generation from
    seamless volumetric maps. Quantization is the process of choosing integers that
    represent the numbers of hexahedral elements to be placed in each region of the
    volume, and transforming the seamless map into an integer‐grid map matching that
    choice, inducing a hexahedral mesh. Previous work computes such quantizations
    under the restriction of a fixed predetermined singularity graph. Our novel approach
    allows for implicit modification and, in particular, simplification of the map's
    singularity structure wherever that benefits the chosen objective, such as matching
    target hexahedron sizes as closely as possible. It comes with two novel ingredients:
    A feature‐focused distortion measure guiding the quantization, and constraints
    ensuring map injectivity and structure preservation of geometric and topological
    features, both without relying on a fixed singularity structure. We demonstrate
    the benefit of the added flexibility offered by this approach: it allows for the
    generation of hexahedral meshes that more accurately match a desired resolution
    globally, as well as of meshes exhibiting a simpler block structure.</jats:p>"

  text: In diesem Forschungsprojekt wurde ein Messverfahren zur Bestimmung akustischer
    Materialparameter von Polymeren im Ultraschallfrequenzbereich entwickelt. Das
    Verfahrens sollte, die üblichen standardisierten Prüfmethoden erweitern, die bislang
    primär im quasistatischen oder niederfrequenten Bereich eingesetzt wurden. Im
    Gegensatz zu bestehenden Verfahren wie dem Zeitstandversuch oder der Dynamisch
    Mechanischen Analyse (DMA) nach [DIN6721] sollte die neue Methode eine nicht-invasive
    Charakterisierung der (visko-)elastischen Materialparameter im Frequenzbereich
    von 0,75 MHz bis 2,5 MHz ermöglichen. Das entwickelte Ultraschallmesssystem arbeitet
    nach dem Puls Echo-Prinzip und kann eine räumlich segmentierte, ringförmige Anregung
    erzeugen. Die Bestimmung der frequenzabhängigen Materialparameter geschieht hierbei
    über ein inverses Verfahren. Die Ergebnisse des Projekts zeigen, dass die Segmentierung
    der Anregung, die Geometrie der Probe sowie das Puls-Echo-Messprinzip die Messergebnisse
    sowie die Sensitivität gegenüber Scherparametern wesentlich beeinflussen. Im Rahmen
    des Projektes wurde auch eine statistische Auswertung des Optimierungsverfahrens
    hinsichtlich transversal-isotroper Materialsymmetrie mit Rayleigh-Dämpfung durchgeführt.
    Die Ergebnisse zeigen, dass das entwickelte Verfahren gute Konvergenzeigenschaften
    aufweist und sich durch verbesserte Robustheit auszeichnet.

  text: This research project involved developing a measurement method to determine
    the acoustic material parameters of polymers within the ultrasonic frequency range.
    The aim of this method is to extend the range of standardised tests that operate
    in the quasi-static or low-frequency range. In contrast to existing methods such
    as the creep test or dynamic mechanical analysis according to [DIN6721], the developed
    method is capable of non-invasive characterisation of the (visco-)elastic material
    parameters in the frequency range of 0,75 MHz bis 2,5 MHz. The developed ultrasonic
    measurement setup utilises the pulse-echo principle and can generate a spatially
    segmented, ring-shaped excitation. The frequency-dependent material parameters
    are determined using an inverse method. The final results of the project show
    that the segmentation of the excitation, the geometry of the specimen and the
    pulse-echo measurement principle have a significant influence on the measurement
    results and the sensitivity to shear movements. As part of the project, a statistical
    evaluation of the optimisation process was also carried out with regard to transversely
    isotropic material symmetry with Rayleigh damping. The results show that the developed
    process has good convergence properties and is characterised by improved robustness.

  text: "Beamsplitters represent fundamental components in both classical and quantum
    optical systems, enabling the distribution of light, as well as the generation
    of interference, superposition, and entanglement. However, optical networks constructed
    from conventional bulk 2 × 2-beamsplitters encounter inherent scalability issues,
    as the number of required beamsplitters scales quadratically with the number of
    optical modes for a fully connected network. Metasurfaces offer a promising route
    to\r\novercome these constraints. By manipulating light at the wavelength scale,
    compact optical components with advanced functionalities can be constructed, which
    address several modes simultaneously. In this work, we design and experimentally
    utilize a metasurface as a multiport beamsplitter. Furthermore, we realized a
    multimode interferometer composed of two cascaded metasurfaces. We characterize
    the individual and cascaded metasurfaces by using classical light, showing controllable
    splitting ratios through tunable phase relations. We then expand the approach
    to quantum light, employing single photons to demonstrate second- and third-order
    photon correlations as well as single photon interference across multiple spatial
    paths. These results establish metasurface-based multiport beamsplitters as a
    scalable and reconfigurable platform bridging classical and quantum photonics. "

  text: Metasurfaces are powerful tools for manipulating light using small structures
    on the nanoscale. In most metasurfaces, near-field couplings are treated as being
    unfavorable perturbations. Here, we experimentally investigate a structure consisting
    of sinusoidally modulated silicon waveguides where near-field coupling of local
    resonances leads to negative coupling, i.e., a negative coupling constant. This
    gives rise to wave-vector-dependent eigenstates of elliptical, linear, and circular
    polarizations. In particular, fully circular polarization states are not only
    present at a single point in momentum space (k-space) but also along a line. This
    circular polarization line, as well as a linear polarization line, emanates from
    a polarization degeneracy at the Dirac point. We experimentally validate the existence
    of these eigenstates and demonstrate the energy-, polarization-, and wave vector
    dependence of this metasurface as well as its sensitivity to fabrication tolerances.
    By tuning the incident k-vector, certain polarization-energy eigenstates are strongly
    reflected, allowing for uses in angle-tunable polarization filters and light sources.

  text: While neural network quantization effectively reduces the cost of matrix multiplications,
    aggressive quantization can expose non-matrix-multiply operations as significant
    performance and resource bottlenecks on embedded systems. Addressing such bottlenecks
    requires a comprehensive approach to tailoring the precision across operations
    in the inference computation. To this end, we introduce scaled-integer range analysis
    (SIRA), a static analysis technique employing interval arithmetic to determine
    the range, scale, and bias for tensors in quantized neural networks. We show how
    this information can be exploited to reduce the resource footprint of FPGA dataflow
    neural network accelerators via tailored bitwidth adaptation for accumulators
    and downstream operations, aggregation of scales and biases, and conversion of
    consecutive elementwise operations to thresholding operations. We integrate SIRA-driven
    optimizations into the open-source FINN framework, then evaluate their effectiveness
    across a range of quantized neural network workloads and compare implementation
    alternatives for non-matrix-multiply operations. We demonstrate an average reduction
    of 17\% for LUTs, 66\% for DSPs, and 22\% for accumulator bitwidths with SIRA
    optimizations, providing detailed benchmark analysis and analytical models to
    guide the implementation style for non-matrix layers. Finally, we open-source
    SIRA to facilitate community exploration of its benefits across various applications
    and hardware platforms.

  text: 'Der eugenetische Roman ist als ein literarisches Genre zu begreifen, das
    biowissenschaftliche, bioethische und biopoetische Dimensionen miteinander verbindet,
    um Grenzen und Konstanten des Mensch(lich)en auszuhandeln. Mindestens seit Darwin
    und Galton sind die Modifizierung des menschlichen Individuums und die Optimierung
    der menschlichen Spezies diskutiert worden, spätestens seit den 1980er Jahren
    haben humangenetische und biotechnologische Entwicklungen den Diskurs neu perspektiviert.
    Literatur trägt zu diesem Diskurs bei, indem sie Erprobungs- und Reflexionsräume
    schafft: Sie modelliert menschliche Subjekte, die in eugenetische Zukunftsszenarien
    eingeschrieben sind, und entwickelt spezifische Erzählweisen, die diese Subjekte,
    ihre Lebensweisen und ihr Lebenswissen, narrativ erfahrbar machen. Fünf eugenetische
    Romane der englisch- und deutschsprachigen Gegenwartsliteratur werden in der Studie
    hinsichtlich Subjektmodellierungen und Narrationsweisen im Kontext der Eugenetik
    untersucht.'

    is an integral part of modern societies and therefore school education, and in
    particular mathematics education, should develop students’ risk literacy. Students’
    risk literacy is part of the interdisciplinary research project siMINT (Understanding
    complex STEM topics: Using simulations to promote competences for the 21st century).
    One first challenge in this project was to find a common ground for the inconsistently
    conceptualised terms of risk and risk literacy. Consequently, the aim of this
    paper is to contribute to the conceptualisation of risk and risk literacy. The
    first part of this paper provides a literature review on these areas, resulting
    in a working conceptualisation of the two concepts. We further carried out two
    consecutive steps of a Delphi study with\r\n                    <jats:italic>N</jats:italic>\r\n
    \                    = 15 and\r\n                    <jats:italic>N</jats:italic>\r\n
    \                    = 12 experts respectively, to develop a common conceptualisation
    based on the plurality of different dimensions and elements of risk and risk literacy.
    Based on the results of the first step of the Delphi study, we modified our working
    conceptualisation, using a common model of risk and risk literacy with different
    dimensions. In the second step of the Delphi study, the experts comment on (i) the
    dimensions and (ii) the elements of risk and risk literacy in these dimensions.
    The results showed that the experts are able to locate their individual definitions
    of risk in the model with three dimensions (relation between risk/uncertainty,
    connotation, and mathematical object) that we developed and to formulate reasons
    for their allocation. Furthermore, the results revealed that risk literacy consists
    of subsets of mathematical and non-mathematical elements that the experts rate
    differently with regard to their importance. In general, the results contribute
    to clarifying the constructs of risk and risk literacy as a basis for developing
    approaches to improve risk literacy.\r\n                  </jats:p>"

  text: "<jats:p>\r\n                    There is a contradiction between seven meta-analyses,
    all of which indicate a substantial benefit of the flipped classroom (FC) method
    for K-12 teaching and some larger study that found no such benefit when compared
    to “traditional” teaching. In the theoretical part of the paper, we shed light
    on this contradiction by consulting general literature on meta-analyses. Ranking
    the 50 included FC studies by the number of classes per experimental condition,
    we found a negative correlation between the “size” of a study and the effect in
    favor of FC. In the empirical part, we present an FC study with three conditions
    concerning mathematical teaching, based on\r\n                    <jats:italic>n</jats:italic>\r\n
    \                    = 950 students aged 11–13, in which many relevant covariates
    (e.g., quality of instruction) were addressed. One FC condition was based on students’
    knowledge acquisition through instructional videos at home (FCn:\r\n                    <jats:italic>n</jats:italic>\r\n
    \                    = 12 classes). Considering that self-regulation support might
    play a crucial role especially for young students working at home, another FC
    condition (FCS:\r\n                    <jats:italic>n</jats:italic>\r\n                     = 12
    classes) was implemented, in which students could learn additional math-free strategies
    concerning watching instructional videos. Both FC-conditions were experimentally
    compared with a control group of traditional teaching (TT:\r\n                    <jats:italic>n</jats:italic>\r\n
    \                    = 13 classes). No significant effect on learning gains was
    found between FCn and TT, indicating that “flipping” alone may not be more effective
    per se. However, a significant difference was found between FCS and FCn. Thus,
    supporting students’ self-regulation in addition may in indeed open the door to
    successful FC, even with very young students.\r\n                  </jats:p>"
