  text: 'Der Beitrag konzentriert sich am Beispiel des IVAR Planers auf die virtuellen
    Einrichtungstools des Einrichtungskonzerns IKEA und fragt danach, welche Politiken
    des Wohnens und Einrichtens sich aus der Medialität dieser virtuellen Umgebungen
    ergeben. Anhand von Stefan Riegers Überlegungen zum virtuellen Testen werden diese
    Planungstools einerseits als auf Dauer gestellte Testumgebungen verstanden, die
    es den Kund*innen erlauben, das eigene Zuhause – ökologisch wie ökonomisch niederschwellig
    – virtuell immer wieder einzurichten. Andererseits werden die Anrufungen zur Kreativität,
    die ständig an die Kund*innen gerichtet werden, in die Überlegungen mit einbezogen,
    weil sich daraus eine paradoxe Konstellation ergibt: Zum einen sollen so die virtuellen
    Einrichtungstools kreatives Potenzial und eigenständige Gestaltung aufrufen; zum
    anderen werden diese Aufrufe aber durch die Medialität der Tools eingehegt und
    damit zu einem Steuerungsregime.'

  text: 'Using the example of the IVAR planner, the article focuses on the virtual
    furnishing tools of the furniture company IKEA and asks which policies of living
    and furnishing result from the mediality of these virtual environments. Based
    on Stefan Rieger’s reflections on virtual testing, these planning tools are understood
    on the one hand as permanent test environments that allow customers to furnish
    their own homes virtually again and again – in an ecologically and economically
    low-threshold way. On the other hand, the appeals for creativity that are constantly
    made to customers are included in the considerations because this results in a
    paradoxical constellation: On the one hand, the virtual furnishing tools are intended
    to invoke creative potential and independent design; on the other hand, however,
    these invocations are contained by the mediality of the tools and thus become
    a control regime.'

  text: Unter welchen historischen Bedingungen und mit welchen Auswirkungen wurde
    der Computer zum Bestandteil des Wohnalltags? Und wie verhält es sich dabei mit
    Praktiken des Wohnens und Wohnungseinrichtens? Die Beiträger*innen werfen einen
    Blick auf die Computerisierung des Zuhauses und zeigen, wie sie sich vollzieht.
    Der Fokus ihrer Analysen liegt einerseits darauf, wie Arbeit und Assistenz das
    Wohnen im Hinblick auf den Computer prägen. Andererseits denken sie den Computer
    aus der Perspektive der Wohnumgebungen neu und geben so einen kompakten medienhistorischen
    Überblick über den Beginn des Smart Homes.

  text: Cobalt spinel (Co3O4) catalysts are widely studied in scope of the electrocatalytic
    oxygen evolution reaction (OER), yet the role of interfacial structural transformation
    under anodic bias remains under debate. Here, we employ an operando approach,
    combining a fast electrochemical quartz crystal microbalance with dissipation
    monitoring (EQCM-D), electrochemical impedance spectroscopy (EIS), and Raman spectroscopy
    to investigate interfacial transformations of Co3O4 nanoparticle electrodes in
    alkaline electrolyte. We identify two distinct regimes during the anodic sweep
    prior to the macroscopic OER onset. At lower potentials, the catalyst interface
    remains mechanically rigid while reversibly associating several OH−/H2O species
    per oxidized cobalt site. At higher potentials, pronounced softening of the interface
    occurs alongside further uptake of electrolyte species. This indicates amorphization
    and a ‘swelling process’ beyond simple adsorption. Notably, an electrochemical
    conditioning treatment can suppress mass and compliance hysteresis without affecting
    OER activity, suggesting that most incorporated electrolyte species do not participate
    in the OER. EIS further reveals that OER intermediates form well below the apparent
    OER onset potential. These results advance our mechanistic understanding of interfacial
    transformations in cobalt-based OER catalysts and establish EQCM-D as a sensitive
    operando technique for probing electrocatalyst transformations.

  text: "Translated from German, The Handbook of Qualitative and Quantitative Content
    Analysis is a comprehensive handbook which offers an application-orientated introduction
    to qualitative and quantitative content analysis methods.\r\n\r\nThe book provides
    explanations for beginners from bachelor level onwards on how to select an appropriate
    qualitative or quantitative content analysis method and how to use the chosen
    method(s) depending on research interest and amount of data. Part 1 defines the
    basics of qualitative and quantitative content analysis and empirical research,
    including research quality conventions and how to do interpretation; Part 2 is
    a practical guide to classical qualitative content analysis and semi-automated
    quantitative content analysis; and Part 3 introduces Python alongside automated
    techniques such as correspondence analysis, semantic network analysis, sentiment
    analysis, and topic modelling using generative and deep learning algorithms. Each
    of these sections are enriched with extensive examples and cover a range of software
    applications, including AntConc, MAXQDA, Python, and VosViewer.\r\n\r\nThis is
    the ideal resource for anyone interested in content analysis research methods
    across the social sciences, humanities, and data sciences."

  text: "This volume presents  insights from the 2025 ITS-Colloquium on Comparative
    Theology and So-cial Work, exploring how theological concepts and interreligious
    dialogue inform and critically engage  social practice. \r\nDrawing on insights
    \ from education, psychosocial support, military chaplaincy, and community-building,
    it reveals the transformative potential of comparative theology in addressing
    migration, marginalization, and social fragmentation. The contributions critically
    examine the ethical depth and practical challenges of integrating religious perspectives
    into social work, offering valuable insights for theory and praxis in pluralistic
    societies, while also showing the limits and challenges of theoretical models.\r\nOverall,
    when critically and contextually applied, impulses from comparative theology offer
    both conceptual depth and practical tools for ethical, inclusive, and transformative
    social engagement.\r\n\r\n"

  text: In this contribution, we address the estimation of the frequency-dependent
    elastic parameters of polymers in the ultrasound range, which is formulated as
    an inverse problem. This inverse problem is implemented as a nonlinear regression-type
    optimization problem, in which the simulation signals are fitted to the measurement
    signals. These signals consist of displacement responses in waveguides, focusing
    on hollow cylindrical geometries to enhance the simulation efficiency. To accelerate
    the optimization and reduce the number of model evaluations and wait times, we
    propose two novel methods. First, we introduce an adaptation of the Levenberg–Marquardt
    method derived from a geometrical interpretation of the least-squares optimization
    problem. Second, we introduce an improved objective function based on the autocorrelated
    envelopes of the measurement and simulation signals. Given that this study primarily
    relies on simulation data to quantify optimization convergence, we aggregate the
    expected ranges of realistic material parameters and derive their distributions
    to ensure the reproducibility of optimizations with proper measurements. We demonstrate
    the effectiveness of our objective function modification and step adaptation for
    various materials with isotropic material symmetry by comparing them with the
    Broyden–Fletcher–Goldfarb–Shanno method. In all cases, our method reduces the
    total number of model evaluations, thereby shortening the time to identify the
    material parameters.

  text: Light-emitting diodes (LEDs) are becoming increasingly important across various
    sectors of the lighting industry and are being used more frequently. In the field
    of symbolic projection, research is increasingly focusing on implementing light
    modulation using energy-efficient, incoherent LEDs rather than lasers. Since light
    modulation in micro- and nano-optics is typically achieved through phase modulation,
    Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The
    objective of this article is to investigate different approaches for approximating
    incoherent monochromatic light sources within FDTD simulations. To this end, two
    approaches based on dipole sources are considered, as well as a method involving
    plane waves with modulated wavefronts based on Cosine–Fourier functions and a
    method based on the superposition of Gaussian beams. These methods are evaluated
    in terms of their accuracy using a two-dimensional double-slit configuration and
    are compared against a fully incoherent analytical reference.

  text: "Industrial electrification is increasing to reduce fossil fuel dependence,
    alongside a growing share of volatile renewables.\r\nA secure and reliable energy
    supply is crucial for industry, leading to a shift from centralised to decentralised
    grid structures.\r\nDC microgrids becoming increasingly popular in industry, since
    they enable energy recuperation from braking, reduce components and cables, and
    integrate storage and local generation to manage supply interruptions or peak
    loads.\r\nEVs add further synergies by serving as mobile storage units, helping
    to store and redistribute locally generated renewable energy.\r\nThis paper analyses
    how EV integration in droop-controlled DC grids can contribute to a more stable,
    low-emission and peak-reduced load profile to the supply grid through load shifting
    and bridge interruptions.\r\nA droop-controlled DC grid model has been developed,
    incorporating an EV charging park based on probability functions.\r\nScalable
    scenarios allow for diverse condition analysis using an energy management system
    that utilises fuzzy logic and sequential MILP optimisation.\r\nIt has been shown
    that a 7% improvement of coefficient represented grid-serving behaviour is possible
    by load shifting.\r\nIt has also been demonstrated that an optimised EMS can reduce
    the demand-based CO2 emissions by 41kg for a representative day compared to a
    fuzzy logic EMS.\r\nAt the same time peak load is decreased yielding a more constant
    residual load.\r\nThese results highlight the potential of a controlled bidirectional
    charging infrastructure in DC grids and underscore the need to explicitly consider
    charging processes to ensure a residual load as constant as possible."

  text: Proton exchange membranes (PEMs) are essential for fuel cells, yet conventional
    materials like Nafion suffer from humidity dependence and limited thermal stability.
    This study introduces sulfonated phenylene-bridged periodic mesoporous organosilicas
    (PMOs) as promising inorganic–organic hybrid PEMs, synthesized via surfactant-templating
    with varying alkyl chain lengths for different mesopore sizes. Post-synthetic
    functionalization involves nitration of phenylene moieties, reduction to amines,
    and ring-opening of propane or butane sultones to graft sulfonic acid groups via
    flexible spacers, achieving homogeneous distribution along pore walls. Post-functionalization
    is confirmed by powder X-ray diffraction (PXRD), revealing preserved 2D hexagonal
    p6mm ordering and phenylene stacking. N2 physisorption shows type IV isotherms
    with reduced pore volumes and pore sizes. 1H NMR is used to quantify functionalization
    degrees. Impedance spectroscopy on pressed pellets demonstrates proton conductivities
    up to 2 × 10−3 S cm−1 at 30 °C and 90% RH, depending on the functionalization
    degree, confirming sulfonic acid-mediated conduction.

  text: "When do two irreducible polynomials with integer coefficients\r\n  define
    the same number field? One can define an action of\r\n  $\\mathrm{GL}_2 \\times
    \\mathrm{GL}_1$ on the space of polynomials of degree $n$ so that for any two\r\n
    \ polynomials $f$ and $g$ in the same orbit, the roots of $f$ may be expressed\r\n
    \ as rational linear transformations of the roots of $g$; thus, they generate\r\n
    \ the same field. In this article, we show that almost all polynomials of\r\n
    \ degree $n$ with size at most $X$ can only define the same number field as\r\n
    \ another polynomial of degree $n$ with size at most $X$ if they lie in the\r\n
    \ same orbit for this group action. (Here we measure the size of polynomials by\r\n
    \ the greatest absolute value of their coefficients.)\r\n  This improves on work
    of Bhargava, Shankar, and Wang, who proved a similar\r\n  statement for a positive
    proportion of polynomials. Using this result, we\r\n  prove that the number of
    degree $n$ fields such that the smallest polynomial\r\n  defining the field has
    size at most $X$ is asymptotic to a constant times\r\n  $X^{n+1}$ as long as $n\\geq
    3$. For $n = 2$, we obtain a precise asymptotic of\r\n  the form $\\frac{27}{π^2}
    X^2$."

  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>\r\n                    Many
    Android apps collect data from users, and the European Union’s General Data Protection
    Regulation (GDPR) mandates clear disclosures of such data collection. However,
    apps often use third-party code, complicating accurate disclosures. This paper
    investigates how accurately current Android apps fulfill these requirements. In
    this work, we present a multi-layered definition of privacy-related data to correctly
    report data collection in Android apps. We further create a dataset of privacy-sensitive
    data classes that may be used as input by an Android app. This dataset takes into
    account data collected both through the user interface and system APIs. Based
    on this, we implement a semi-automated prototype that detects and labels privacy-related
    data collected by a given Android app. We manually examine the data safety sections
    of 70 Android apps to observe how data collection is reported, identifying instances
    of over- and under-reporting. We compare our prototype’s results with the data
    safety sections of 20 apps revealing reporting discrepancies. Using the results
    from two Messaging and Social Media apps (Signal and Instagram), we discuss how
    app developers under-report and over-report data collection, respectively, and
    identify inaccurately reported data categories. A broader study of 7,500 Android
    apps reveals that apps most frequently collect data that can\r\n                    <jats:italic>partially
    identify</jats:italic>\r\n                    users. Although system APIs consistently
    collect large amounts of privacy-related data, user interfaces exhibit some more
    diverse data collection patterns. A more focused study on various domains of apps
    reveals that the largest fraction of apps collecting personal data belong to the
    domain of\r\n                    <jats:italic>Messaging and Social Media</jats:italic>\r\n
    \                   . Our findings show that location is collected frequently
    by apps, specially from the\r\n                    <jats:italic>E-commerce and
    Shopping</jats:italic>\r\n                    domain. However, it is often under-reported
    in app data safety sections. Our results highlight the need for greater consistency
    in privacy-aware app development and reporting practices.\r\n                  </jats:p>"
