  text: <jats:p>Die Frage, ob bei einer Verbraucherbürgschaft, die in einer Außergeschäftsraumsituation
    abgegeben worden ist, ein Wider-rufsrecht besteht, ist seit nunmehr 30 Jahren
    umstritten. Der BGH hatte im Jahr 2020 in einem Grundsatzurteil das Widerrufsrecht
    abgelehnt - nur neun Monate vor der erneuten Ände-rung des für diese Frage entscheidenden
    § 312 BGB. Der Beitrag zeigt, dass die Abgabe einer Bürgschaftserklärung notwendigerweise
    mit der Bereitstellung personenbezogener Daten verbunden ist. Dies eröffnet aufgrund
    des überobligatorisch weit gefassten Tatbestands des neuen § 312 Abs. 1a BGB den
    Anwendungsbereich des Verbrauchervertragsrechts und begründet damit das Widerrufsrecht
    nach § 312g BGB.</jats:p>

  text: Light-assisted metal oxide-based chemiresistive gas sensors are widely explored
    for operation at relatively low temperatures, yet the investigation of the role
    of irradiance, as opposed to wavelength, remains underrepresented. Here, we systematically
    quantify the irradiance-dependent behavior of ordered mesoporous In2O3 under visible
    light illumination. Photoconductivity measurements reveal two distinct irradiance
    regimes consistent with trap-limited transport at low power and recombination-
    or saturation-limited transport at high power. Gas sensing experiments towards
    CO and H2 show a pronounced non-monotonic response, reaching maximum responses
    of 0.74 for 135 ppm CO at 67 mW cm−2 and 0.64 for 90 ppm H2 at 11 mW cm−2, followed
    by strong suppression at higher irradiance. Illumination also accelerated the
    response kinetics. At 60 ppm, t90 decreases from 96 to 12 s for CO and 141 to
    27 s for H2, corresponding to an 8- and 5-fold faster response time, respectively.
    Near-ambient pressure-XPS under controlled atmosphere and density functional theory
    calculations indicate defect-mediated excitation. Oxygen vacancy states and illumination-induced
    modification of surface oxygen species govern this behavior. The results establish
    irradiance as a critical mechanistic parameter that determines whether In2O3 operates
    in a surface-controlled or bulk photoconductive regime. These findings highlight
    the need to explicitly optimize and report irradiance in illuminated gas sensor
    studies, and not only the power consumption of the light source.

  text: '<jats:p>Magnetron-sputtered CNx thin films are primarily employed as hard,
    low-friction protective and tribological coatings, as solar cells, and for catalytic
    applications. Lower growth rates and a reduced N content, favoring graphitic sp2
    structures, hinder industrial scalability due to prolonged deposition times and
    produce softer, less dense films with inferior hardness, elasticity, and wear
    resistance. Carbon nitride films deposited by magnetron sputtering exhibit growth
    behavior strongly influenced by plasma–surface interactions. However, nitrogen
    resputtering and reduced film growth rates are commonly attributed to chemical
    etching by positive ions. We propose an additional, unreported power-dependent
    mechanism involving negative ions formed at the carbon target. These ions are
    accelerated through the plasma sheath, reaching the substrate with high kinetic
    energy and inducing both chemical and physical resputtering. This effect is localized
    to the geometrical projection of the target, as shown by spatially resolved analysis:
    ellipsometry reveals thickness reduction, and x-ray photoelectron spectroscopy
    and Raman spectroscopy indicate nitrogen depletion within this region. Correlation
    between stoichiometry and structural signatures confirms the decisive role of
    negative ions in modifying the film composition and microstructure. At the same
    time, the composition of the gas mixture exerts only a minor effect.</jats:p>'

    joining processes have played an increasingly important role in the manufacturing
    of modern lightweight structures due to a greater variety of materials. The growing
    number of joining tasks requires a large number of joining elements. Friction
    spun joint connectors (FSJC) offer an innovative approach that meets the growing
    demand for flexibility. This process combines rotational movement and axial force
    to create targeted friction heating, enabling the production of FSJCs and the
    joining of various sheet metal materials. The shape of the FSJC can be optimally
    adapted to the joining situation in question, providing a significant advantage
    in terms of process chain versatility. This paper investigates FSJCs made of the
    steel grades C45E+C (1.1191) and 115CrV3 (1.2210), the effect of in situ quenching
    during the joining process. The influences of the essential parameters of rotational
    speed, feed rate, and FSJC length on the mechanical properties after quenching
    are being focused on and compared to similar conditions during joining without
    quenching. At the same time, the material change is analyzed to determine the
    effect of different alloy approaches on hardness profiles and strength characteristics
    in cross-tensile testing. For this purpose, systematic test series with varying
    process parameters are conducted and evaluated using hardness measurements and
    cross-tensile tests.</jats:p>"

  text: We study the large-time behavior of the continuous-time heat kernel and of
    solutions to the heat equation on homogeneous trees. First, we derive sharp asymptotic
    formulas for the heat kernel as $t\to\infty$. Second, using them, we show that
    solutions with initial data in weighted $\ell^1$ classes, asymptotically factorize
    in $\ell^p$ norms, $p\in[1,\infty]$, as the product of the heat kernel, times
    a $p$-mass function, dependent on the initial condition and $p$. The  $p$-mass
    function is described in terms of boundary averages associated with Busemann functions
    for $p<2$, while for $p\ge 2$, it is expressed through convolution with the ground
    spherical function. For comparison, the case of the integers shows that a single
    constant mass determines the asymptotics of solutions to the heat equation for
    all $p$, emphasizing the influence of the graph geometry on heat diffusion.

  text: In this paper we study a variant of the uncentred Hardy--Littlewood maximal
    operator on Damek--Ricci spaces in which balls are replaced by suitable half balls.
    Perhaps surprisingly, such modified maximal operator has better boundedness properties
    than the classical one. In particular, it satisfies an $L\log L$ endpoint estimate
    and it is bounded on $L^p$ for every $p$ in $(1,\infty]$.

  text: The circular economy offers decisive advantages over the currently prevalent
    linear economy in industry. Firstly, the reuse of products, individual parts and
    material reduces the need for new production or generation and the associated
    consumption of energy and resources. Secondly, it helps to avoid the generation
    of waste. Early consideration of circular economic principles in product development
    processes is essential to specifically promote reuse, reparability and recycling.
    Efficient recycling of assemblies requires well-defined strategies. However, various
    challenges hinder the efficiency of technical recycling processes in industrial
    applications. This paper presents an Ishikawa (fishbone) diagram-based approach
    to systematically identify and categorize these influences. The method is implemented
    within an industrial framework, highlighting key obstacles such as material composition,
    design constraints, use of technology, framework conditions, economic limitations
    and regulatory challenges. By applying a scenario analysis, this approach examines
    potential future developments and their impact on recycling-oriented design choices.
    This helps to identify critical influencing factors and supports the development
    of resilient and sustainable industrial practices. This framework will serve as
    the foundation for developing an automated approach to circular design, enabling
    industries to more effectively integrate sustainability into their processes and
    adapt to changing environmental demands.

  text: Political goals, emerging EU sustainability regulations, and industrial digitalization
    are driving the introduction of Digital Product Passports (DPPs) to enhance transparency,
    traceability, and compliance across product life cycles. However, the appropriate
    granularity of DPP integration across product architectures remains ambiguous.
    This paper introduces a structured, decision-oriented framework that links product
    structure, regulatory relevance, and information depth to define consistent DPP
    levels, supporting both industry implementation and future standardization.

  text: 'In June 2025, Iran enacted a nationwide Internet shutdown, culminating its
    already strict censorship apparatus. While Internet shutdowns happen regularly,
    insights into these shutdowns are notoriously difficult to obtain: their timing
    is hard to predict, and measurements are often impossible. In this paper, we present
    unique measurements surrounding Iran’s 2025 Internet shutdown in June, which we
    acquired during a regular analysis of Iran’s censorship apparatus. We contextualize
    our findings of Iranian DNS, HTTP, TLS, and QUIC censorship during the shutdown
    with measurements from platforms such as Cloudflare Radar and user reports. Our
    measurements show that Iranian censorship changed before and after the shutdown,
    marking preparation and recovery periods. For instance, QUIC censorship went into
    effect before and stayed in effect after the shutdown, while DNS over TCP censorship
    was only present briefly before the shutdown and resumed working afterwards. We
    also measured general network instabilities, especially for UDP, after the shutdown
    and the disabling of certain middleboxes. Our findings indicate that the Iranian
    censor enforced its shutdown using fine-grained techniques instead of relying
    on an all-or-nothing blackout. We advertise for continued measurements of the
    Iranian censor and hypothesize that future shutdowns in censoring countries could
    be detected during their preparation phase.'

  text: 'Governments around the world limit free access to information through Internet
    censorship. With the rising adoption of the QUIC protocol, these censors have
    been forced to evolve their systems. Russia introduced sweeping changes to its
    censorship after its full-scale invasion of Ukraine, including completely blocking
    international QUIC connections. However, after this broad filter was identified
    in 2022, Russian QUIC censorship received little attention: The current state
    of QUIC censorship by TSPU devices is largely unknown. In this paper, we provide
    a timeline of Russian QUIC censorship and detail its current state. We identify
    that Russian TSPU devices switched to SNI-dependent QUIC censorship on a large
    scale between May 2022 and July 2023, a fact that went largely unnoticed for three
    years. While the GFW was previously thought to be the first censor with broad
    SNI-dependent QUIC censorship, we highlight that Russian TSPU devices broadly
    adopted SNI-dependent QUIC censorship at least nine months before the GFW. We
    consider this an indicator of the TSPU devices’ flexibility and of Russia’s willingness
    to invest in strict and up-to-date censorship.'
