  text: "Despite recent progress in Large Language Model (LLM) research, LLMs remain
    sensitive to prompt paraphrases,\r\ne.g., due to sycophancy, framing, or negation
    blindness, yielding surprising and contradictory outputs. This paper\r\ninvestigates
    whether such vulnerabilities can be exploited to construct adversarial attacks
    against LLMs. Using\r\na DeepSeek-V4-Flash model, we automatically rephrase an
    input prompt using sycophancy, framing, and/or\r\nnegations to leave it semantically
    unchanged but elicit a contradicting output of a victim LLM, in this case a\r\nLlama-3.1-8B-Instruct
    model. On 49 controversial topics, we show that negation attacks can flip the
    model’s\r\noriginal stance in roughly 80% of cases, whereas sycophancy and framing
    yield moderate success rates around\r\n25% and 40%, respectively. The attacker
    LLM was also quite accurate in determining attack success (91.3%\r\naccuracy compared
    to annotations of two independent human annotators). Overall, the results suggest
    that\r\nhuman-interpretable paraphrase attacks, such as negations, may be a viable
    method to illustrate the vulnerabilities\r\nof LLMs."

  text: "<jats:title>ABSTRACT</jats:title>\r\n                  <jats:p>Hybrid modeling
    aims to combine physical and data‐driven models to increase simulation accuracy
    without losing physical interpretability. In the context of dynamic mechanical
    systems, this enables the compensation of modeling inaccuracies that arise from
    simplifications, missing effects, or uncertain parameters. In this work, a hybrid
    model is used as a starting point, in which the discrepancy between simulation
    and measurement is learned and compensated by a data‐driven correction element.
    To integrate such models into commercial multibody simulation software like Adams
    or Simpack, the formulation is adapted to operate directly on the force level.
    This allows implementation via standard co‐simulation interfaces without modifying
    the system's differential equations or solvers. The method is demonstrated using
    a three‐mass oscillator with synthetic measurement data. Results show that the
    coupled simulation works reliably and that the hybrid model significantly improves
    accuracy while remaining compatible with established industrial simulation workflows.</jats:p>"

  text: 'Classical shadows are an influential framework for compressing copies of
    a given quantum state $ρ$ into classical data $S$, enabling many properties of
    $ρ$ to be predicted from relatively few copies. In this work, we study two natural
    questions involving shadows: (1) Given $S$, when can one efficiently verify that
    $S$ came from a genuine $n$-qubit state? This is called the Classical Shadow Validity
    (CSV) problem, introduced by Karaiskos, Rudolph, Meyer, Eisert, and Gharibian
    [ICALP 2026]. (2) Given $S$ that allows one to capture 2-local properties of $ρ$,
    can one fake or spoof a shadow $S''$ which predicts 3-local properties of some
    state? For (1), we show CSV is efficiently solvable for permutation-invariant
    shadows, QMA-hard for real, fermionic, and bosonic shadows, and both coNP-hard
    and QMA-hard when the observable family consists of all $n$-qubit Pauli strings.
    A result of independent interest along the way is a new upper bound qc-$Σ_2$ $\subseteq$
    $\mathrm{P}^{\mathrm{PP}}$, where qc-$Σ_2$ is a quantum analogue of the second
    level of the polynomial hierarchy in which the first proof is quantum. For (2),
    we show intractability: Given the 2-local marginals $S$ of a quantum state $ρ$,
    estimating the 3-local marginals of $ρ$ is intractable unless QCMA $\subseteq$
    BPP, even if the state $ρ$ is the unique state consistent with $S$.'

  text: Low-energy estimation and state preparation for general $k$-local Hamiltonians
    are fundamental challenges in quantum complexity theory. Buhrman et al.~ [BGLGST,
    PRL 2025] recently broke the natural Grover bound $O^\ast(2^{n/2})$ for both problems,
    with the improvement depending on the relative accuracy $\varepsilon$ and the
    locality $k$. In this work, we present faster exponential quantum algorithms for
    these problems, where the binary entropy function governs the runtime exponent.
    For sufficiently small $\varepsilon/k$, our algorithms improve the exponent by
    a factor of $\log(k/\varepsilon)$ over [BGLGST, PRL 2025]. Our main technical
    result is an entropy-governed lower bound on the dimension of the Hamiltonian's
    low-energy subspace, obtained by depolarizing its ground state. For fixed $k$,
    this bound is optimal up to constant factors in the exponent. The same framework
    yields tighter bounds for Heisenberg, $XY$, and Ising models on arbitrary interaction
    graphs.

  text: "We rigorously derive novel and sharp finite-data error bounds for highly\r\nsample-efficient
    Extended Dynamic Mode Decomposition (EDMD) for both i.i.d. and\r\nergodic sampling.
    In particular, we show all results in a very general setting\r\nremoving most
    of the typically imposed assumptions such that, among others,\r\ndiscrete- and
    continuous-time stochastic processes as well as nonlinear partial\r\ndifferential
    equations are contained in the considered system class. Besides\r\nshowing an
    exponential rate for i.i.d. sampling, we prove, to the best of our\r\nknowledge,
    the first superlinear convergence rates for ergodic sampling of\r\ndeterministic
    systems. We verify sharpness of the derived error bounds by\r\nconducting numerical
    simulations for highly-complex applications from molecular\r\ndynamics and chaotic
    flame propagation."

  text: Optimizing large-scale multibody systems is a challenging task, particularly
    in the presence of multiple conflicting criteria. To prevent high simulation costs,
    surrogate models constructed from a small number of expensive model evaluations
    are very popular. However, it is difficult to ensure the optimality of the obtained
    solutions using a single pre-computed model. We present a back-and-forth approach
    between surrogate modeling and multi-objective optimization, and we compare different
    strategies for optimization, sampling, and surrogate modeling, to identify the
    most promising approach in terms of computational efficiency and solution quality.

  text: 'This research provides a method for designing competenceoriented, modular
    workflows that support strategic decisionmaking in strategic product planning
    (SPP) under conditions of uncertainty and time pressure. Increasing digitalization
    and data availability require decision support systems that integrate analytical
    models while being tailored to the competencies of decision-makers. Based on a
    systematic literature review and stakeholder workshops, eight success factors
    for competency-oriented workflow integration are identified, including modularity,
    traceability, interoperability, adaptability, handling uncertainty, and user acceptance.
    Based on these factors, a five-step method is developed that links business processes,
    data sources, evaluation criteria, visualization formats, and graphical workflow
    implementation. Strategic and technical decision logic are integrated into a unified,
    modular framework using graphical modeling environments. The method is validated
    in workshops and demonstrates its applicability in time-critical, multi-criteria
    decision contexts. The results show improved transparency, adaptability, and practical
    usability of datadriven decision processes that support robust and traceable business
    decisions. '

  text: <jats:p>For foresightful strategic decisions in engineering and production,
    it is important to identify and classify operational engineering data inmanufacturing
    companies in terms of relevance and impact. Established methods like Scenario-Technique
    or roadmapping consider expertise of strategic decision-makers and central decision-making
    bodies by, for instance, workshops and interviews. There is no overarching approach
    for evaluating the variety of operational data sources and feed them into specific
    data processing pipelines targeting strategic decision support. Based on a systematic
    literature analysis and comprehensive industrial experience, requirements are
    derived. These requirements are used to develop a method to identify, classify
    and evaluate data for strategic decision-making. The method is validated in an
    industrial project. The aim is to exploit informal and fragmented data from operational
    levels into structured, transparent decision support for strategic players.</jats:p>

  text: 'The effects of decisions in strategic product planning are usually far-reaching,
    but at the same time difficult to assess. Simulations help to make these effects
    more tangible. Until now, the use of simulation in strategic product planning
    has been limited to behavioral and innovation diffusion studies. This paper presents
    a process model for widening business models or planning upcoming product generations.
    It supports integrating the simulation of technical systems into decisionmaking
    processes to select the most suitable product for adaptation to new application
    scenarios. To this end, the characteristics of such new application scenarios
    are applied to existing product models in simulation, and the system behavior
    is evaluated based on key figures. This supports the comparison of different products
    and the selection of the product alternative requiring the least amount of modification.
    The process model enables decision-makers to systematically integrate simulation
    into the decision-making process and thus make more data-based decisions. '

  text: We report the synthesis, structural elucidation, and establishment of structure−property
    relationships for two metal−organic frameworks (MOFs), [M(OH)(H2BPD)]·xH2O (M
    = Al3+, Ga3+, x = 11–13), denoted as M-CAU-67, employing the ditopic linker molecule
    N,N′-4,4′ bipiperidine bis(methylenephosphonic acid) (H4BPD). The title compounds
    can be synthesized on a milligram scale under hydrothermal conditions, while gram-scale
    synthesis was realized under reflux conditions. Single-crystal X-ray diffraction
    (SCXRD) revealed an isoreticular, expanded MIL-91 type structure, representing
    a rare case of isoreticular expansion in porous metal phosphonates. The framework
    structure was confirmed by Rietveld refinement against powder X-ray diffraction
    (PXRD) data and further validated by solid-state NMR spectroscopy (31P MAS, 27Al
    3Q MAS). Solvent-exchange experiments and variable-humidity/temperature PXRD data
    revealed high framework flexibility. The compounds show permanent microporosity
    and a complex, polarity- and size-dependent sorption behavior toward gases and
    vapors.

  text: The influence of the hydrophilicity of mesoporous silica on wetting with water
    was investigated by comparing a standard hydrophilic MCM-41 and a partially hydrophobicized
    material obtained by trimethylsilylation of MCM-41. The materials were characterized
    using X-ray diffraction, N2 physisorption, thermogravimetric analysis, infrared
    spectroscopy, as well as 29Si and 13C solid-state nuclear magnetic resonance spectroscopy.
    Trimethylsilylation leads to a reduction of the pore diameter (determined using
    density functional theory) from 3.8 to 3.6 nm. Using proton solid-state nuclear
    magnetic resonance (NMR) under magic-angle spinning, it was found that the filling
    of these narrow pores with increasing amounts of water follows an axial mode,
    independent of surface hydrophilicity. The axial model of pore-filling is supported
    by the coexistence of two characteristic 1H NMR water signals, one from physisorbed
    water molecules, which can exchange protons with silanol groups, and one from
    bulk-like water in completely filled pores, where water molecules are in exchange
    between sites at the pore wall and sites closer to the center of the pore.

  text: <jats:p> Der Vorbereitungsdienst stellt einen zentralen Abschnitt im Professionalisie‍
    rungsprozess angehender Lehrpersonen dar, in dem der Beziehung zwischen Lehramtsanwärter*innen
    (LAA) und Mentor*innen eine besondere Bedeutung zukommt. In Nordrhein-Westfalen
    (NRW) bestehen bislang keine einheitlich formulierten Anforderungen an Mentor*innen,
    was Handlungsspielräume er‍ öffnet und für die konkrete Gestaltung der Arbeitsbeziehung
    viel Spielraum lässt. Der Beitrag widmet sich diesem Themenfeld, indem er Einblicke
    in ein Dissertationsvorhaben gibt, das die Wahrnehmung der Mentoring-Bezie‍ hung
    aus beiden Perspektiven (LAA und Mentor*innen) untersucht. Ziel ist es, zentrale
    Merkmale der Arbeitsbeziehungen zu identifizieren und damit Grundlagen für eine
    gezielte Unterstützung von Mentoring-Prozessen zu lie‍ fern. Interviews mit Seminarleitungen
    und Schulleitungen sowie quantitative Befragungen von LAA und Mentor*innen zeigen
    erste Tendenzen auf und verdeutlichen die Bedeutung von Vertrauen, Wertschätzung
    und Austausch für eine gelingende kooperative Arbeitsbeziehung im Vorbereitungsdienst
