  text: A parallel hybrid quantum-classical algorithm for the solution of the quantum-chemical
    ground-state energy problem on gate-based quantum computers is presented. This
    approach is based on the reduced density-matrix functional theory (RDMFT) formulation
    of the electronic structure problem. For that purpose, the density-matrix functional
    of the full system is decomposed into an indirectly coupled sum of density-matrix
    functionals for all its subsystems using the adaptive cluster approximation to
    RDMFT. The approximations involved in the decomposition and the adaptive cluster
    approximation itself can be systematically converged to the exact result. The
    solutions for the density-matrix functionals of the effective subsystems involves
    a constrained minimization over many-particle states that are approximated by
    parametrized trial states on the quantum computer similarly to the variational
    quantum eigensolver. The independence of the density-matrix functionals of the
    effective subsystems introduces a new level of parallelization and allows for
    the computational treatment of much larger molecules on a quantum computer with
    a given qubit count. In addition, for the proposed algorithm techniques are presented
    to reduce the qubit count, the number of quantum programs, as well as its depth.
    The evaluation of a density-matrix functional as the essential part of our approach
    is demonstrated for Hubbard-like systems on IBM quantum computers based on superconducting
    transmon qubits.

  text: "In backward error analysis, an approximate solution to an equation is compared
    to the exact solution to a nearby ‘modified’ equation. In numerical ordinary differential
    equations, the two agree up to any power of the step size. If the differential
    equation has a geometric property then the modified equation may share it. In
    this way, known properties of differential equations can be applied to the approximation.
    But for partial differential equations, the known modified equations are of higher
    order, limiting applicability of the theory. Therefore, we study symmetric solutions
    of discretized\r\npartial differential equations that arise from a discrete variational
    principle. These symmetric solutions obey infinite-dimensional functional equations.
    We show that these equations admit second-order modified equations which are Hamiltonian
    and also possess first-order Lagrangians in modified coordinates. The modified
    equation and its associated structures are computed explicitly for the case of
    rotating travelling waves in the nonlinear wave equation."

  description: |-
    In backward error analysis, an approximate solution to an equa-
    tion is compared to the exact solution to a nearby ‘modified’ equation. In
    numerical ordinary differential equations, the two agree up to any power of
    the step size. If the differential equation has a geometric property then the
    modified equation may share it. In this way, known properties of differential
    equations can be applied to the approximation. But for partial differential
    equations, the known modified equations are of higher order, limiting appli-
    cability of the theory. Therefore, we study symmetric solutions of discretized
    partial differential equations that arise from a discrete variational principle.
    These symmetric solutions obey infinite-dimensional functional equations. We
    show that these equations admit second-order modified equations which are
    Hamiltonian and also possess first-order Lagrangians in modified coordinates.
    The modified equation and its associated structures are computed explicitly
    for the case of rotating travelling waves in the nonlinear wave equation.

  text: Hamiltonian systems are differential equations which describe systems in classical
    mechanics, plasma physics, and sampling problems. They exhibit many structural
    properties, such as a lack of attractors and the presence of conservation laws.
    To predict Hamiltonian dynamics based on discrete trajectory observations, incorporation
    of prior knowledge about Hamiltonian structure greatly improves predictions. This
    is typically done by learning the system's Hamiltonian and then integrating the
    Hamiltonian vector field with a symplectic integrator. For this, however, Hamiltonian
    data needs to be approximated based on the trajectory observations. Moreover,
    the numerical integrator introduces an additional discretisation error. In this
    paper, we show that an inverse modified Hamiltonian structure adapted to the geometric
    integrator can be learned directly from observations. A separate approximation
    step for the Hamiltonian data avoided. The inverse modified data compensates for
    the discretisation error such that the discretisation error is eliminated. The
    technique is developed for Gaussian Processes.

  text: In control design most control strategies are model-based and require accurate
    models to be applied successfully. Due to simplifications and the model-reality-gap
    physics-derived models frequently exhibit deviations from real-world-systems.
    Likewise, purely data-driven methods often do not generalise well enough and may
    violate physical laws. Recently Physics-Guided Neural Networks (PGNN) and physics-inspired
    loss functions separately have shown promising results to conquer these drawbacks.
    In this contribution we extend existing methods towards the identification of
    non-autonomous systems and propose a combined approach PGNN-L, which uses a PGNN
    and a physics-inspired loss term (-L) to successfully identify the system's dynamics,
    while maintaining the consistency with physical laws. The proposed method is demonstrated
    on two real-world nonlinear systems and outperforms existing techniques regarding
    complexity and reliability.

    von Leistungen vier- bis sechsjähriger Kinder (<jats:italic>N</jats:italic> = 160)
    in 17 Items im Bereich Mengen und Zahlen. Zur Aufklärung von Varianz in der Einschätzungsgenauigkeit
    wurden das Geschlecht, der sozioökonomische Status und die mathematische Leistung
    der Kinder im Bereich Mengen und Zahlen sowie das mathematikdidaktische Wissen
    der Fachkräfte als mögliche Merkmale erhoben. Es zeigte sich im Schnitt eine mäßige
    Einschätzungsgenauigkeit mit einer leichten Tendenz zur Überschätzung der Leistungen.
    Als einziges einflussnehmendes Merkmal auf die Einschätzungsgenauigkeit stellte
    sich in dieser Untersuchung die Leistung der Kinder im Bereich Mengen und Zahlen
    heraus: Die Einschätzung der frühpädagogischen Fachkräfte war genauer, wenn die
    Kinder bessere mathematische Fähigkeiten zeigten. Der sozioökonomische Status
    und das Geschlecht der Kinder sowie das mathematikdidaktische Wissen der Fachkräfte
    zeigten keinen signifikanten Einfluss auf die Einschätzungsgenauigkeit.</jats:p>'

  text: <jats:p> Zusammenfassung. Frühe mathematische Kompetenzen entwickeln sich
    u.a. in der Auseinandersetzung mit Fragestellungen, die sich im Alltag ergeben.
    Dabei begleiten Eltern als primäre Bezugspersonen den Großteil der frühen mathematischen
    Entwicklung. Bedeutend ist dabei die Fähigkeit von Eltern, mathematische Kompetenzen
    ihrer Kinder einschätzen zu können. Auf dieser Basis können sie mit ihren Kindern
    adäquat interagieren und mathematische Lerngelegenheiten ermöglichen. Ziel dieser
    Studie ist es, zu untersuchen, wie genau Eltern die frühen mathematischen Kompetenzen
    ihrer Kinder einschätzen und wovon die Genauigkeit der Einschätzung abhängt. Dazu
    wurden Daten von 131 Kindern im Alter von 4 bis 6 Jahren und ihren Eltern erhoben
    und analysiert. Es zeigte sich eine mittlere bis gute Genauigkeit in der elterlichen
    Einschätzung. Neben der tatsächlichen Leistung des Kindes nahmen der sozioökonomische
    Status (SES) der Familie und das Geschlecht des Kindes Einfluss auf die elterliche
    Einschätzungsgenauigkeit. Aus den Ergebnissen ergeben sich bedeutende Implikationen
    für die pädagogische Praxis. </jats:p>

  text: '<jats:p>There is an increasing interest in sensing applications for a variety
    of analytes in aqueous environments, as conventional methods do not work reliably
    under humid conditions or they require complex equipment with experienced operators.
    Hydrogel sensors are easy to fabricate, are incredibly sensitive, and have broad
    dynamic ranges. Experiments on their robustness, reliability, and reusability
    have indicated the possible long-term applications of these systems in a variety
    of fields, including disease diagnosis, detection of pharmaceuticals, and in environmental
    testing. It is possible to produce hydrogels, which, upon sensing a specific analyte,
    can adsorb it onto their 3D-structure and can therefore be used to remove them
    from a given environment. High specificity can be obtained by using molecularly
    imprinted polymers. Typical detection principles involve optical methods including
    fluorescence and chemiluminescence, and volume changes in colloidal photonic crystals,
    as well as electrochemical methods. Here, we explore the current research utilizing
    hydrogel-based sensors in three main areas: (1) biomedical applications, (2) for
    detecting and quantifying pharmaceuticals of interest, and (3) detecting and quantifying
    environmental contaminants in aqueous environments.</jats:p>'

  text: Subwavelength dielectric resonators assembled into metasurfaces have become
    a versatile tool for miniaturizing optical components approaching the nanoscale.
    An important class of metasurface functionalities is associated with asymmetry
    in both the generation and transmission of light with respect to reversals of
    the positions of emitters and receivers. The nonlinear light–matter interaction
    in metasurfaces offers a promising pathway towards miniaturization of the asymmetric
    control of light. Here we demonstrate asymmetric parametric generation of light
    in nonlinear metasurfaces. We assemble dissimilar nonlinear dielectric resonators
    into translucent metasurfaces that produce images in the visible spectral range
    on being illuminated by infrared radiation. By design, the metasurfaces produce
    different and completely independent images for the reversed direction of illumination,
    that is, when the positions of the infrared emitter and the visible light receiver
    are exchanged. Nonlinearity-enabled asymmetric control of light by subwavelength
    resonators paves the way towards novel nanophotonic components via dense integration
    of large quantities of nonlinear resonators into compact metasurface designs.

  text: The free exciton transition (near-band-edge emission, NBE) of ZnO at ≈388
    nm can be strongly enhanced and even stimulated by an underlying photonic structure.
    1D Photonic crystals, so-called distributed Bragg reflectors, are utilized to
    suppress the deep-level emission of ZnO (DLE, ≈500–530 nm). The reflector stacks
    are fabricated in a layer-by-layer procedure by wet-chemical synthesis. They consist
    of low-ε porous SiO2 layers and high-ε TiO2 layers. Varying the thickness of the
    SiO2 layers allows tuning the optical bandgap in a wide range between ≈420 and
    800 nm. A ZnO layer is deposited on top of the reflector stacks by sol–gel synthesis.
    The spontaneous photoluminescence (PL) emission of the ZnO film is modulated by
    the photonic structure. When the optical bandgap of the reflector is in resonance
    with the deep-level emission of ZnO (DLE, ≈500–530 nm), then this defect-related
    emission mode is suppressed. Strong NBE emission is observed even when the ZnO
    layer does not show any NBE emission (due to low crystallinity) in the absence
    of the photonic structure. With this cost-efficient synthesis method, emitters
    for, e.g., luminescent gas sensors can be fabricated.
