  text: We introduce the notion of contrastive ABox explanations to answer questions
    of the type "Why is a an instance of C, but b is not?". While there are various
    approaches for explaining positive entailments (why is C(a) entailed by the knowledge
    base) as well as missing entailments (why is C(b) not entailed) in isolation,
    contrastive explanations consider both at the same time, which allows them to
    focus on the relevant commonalities and differences between a and b. We develop
    an appropriate notion of contrastive explanations for the special case of ABox
    reasoning with description logic ontologies, and analyze the computational complexity
    for different variants under different optimality criteria, considering lightweight
    as well as more expressive description logics. We implemented a first method for
    computing one variant of contrastive explanations, and evaluated it on generated
    problems for realistic knowledge bases.

  text: 'Spray-induced gene silencing (SIGS) employing double-stranded RNA (dsRNA)
    offers a promising, species-specific approach for protecting crops from insect
    pests such as the cabbage stem flea beetle (Psylliodes chrysocephala). However,
    the environmental instability of dsRNA presents a major limitation to its field
    application. In this study, we evaluate two distinct dsRNA formulation strategies
    for improved stability and delivery: a bottom-up approach using chitosan-based
    interpolyelectrolyte complexes (IPEC) and a top-down approach employing functionalized
    mesoporous silica carriers (SBA-15). Both systems were comprehensively characterized
    in terms of size, surface potential, porosity, and release behavior. The results
    revealed that IPECs exhibited release kinetics that were approximately one order
    of magnitude faster than those of SBA-15 across all tested conditions. The two
    formulations significantly improved dsRNA stability against UV and heat exposure
    compared to free dsRNA. In feeding assays with P. chrysocephala, both carriers
    achieved comparable gene silencing efficacy, though dsRNA@IPEC induced more immediate
    effects, while dsRNA@SBA-15 displayed delayed but ultimately stronger reduction
    in consumed leaf area, consistent with its slower release kinetics. We demonstrate
    that despite structural and mechanistic differences, both delivery platforms effectively
    stabilized and delivered dsRNA, and offered distinct advantages depending on application
    needs. This work highlights how formulation strategies are key to successful SIGS
    and supports the development of robust, field-adaptable formulation technologies
    for sustainable pest management.'

  text: "This study addresses the challenge of insufficient weld penetration in the
    outer thin low-carbon steel during\r\nresistance spot welding of three-layer dissimilar
    stack-ups containing advanced high-strength steels. To overcome\r\nthermal imbalance
    constraints, an innovative strategy leveraging plastic shell containment is proposed
    to elevate\r\nthe expulsion-free heat input threshold. By applying a combined
    preheating and ramping current profile, a coordinated “shell-first, nugget-second”
    sequence is achieved. This mechanism creates a solid-state barrier prior to\r\nrapid
    fusion, effectively preventing expulsion. Experimental results demonstrate that
    while the reference\r\nconstant-current schedule fails to maintain a process window
    under a 2 mm initial gap (IG) disturbance, the\r\nproposed strategy significantly
    enhances process stability. It increases the maximum expulsion-free heat input
    by\r\n24 % (to 6338 J) under normal conditions and by 77 % (to 6482 J) under the
    IG condition. Crucially, the\r\nincreased heat input drives nugget growth across
    all interfaces, achieving a penetration depth of 0.38 mm (48 %\r\npenetration
    ratio) in the low-carbon steel sheet under the gap condition. These findings validate
    the strategy’s\r\neffectiveness in ensuring weld quality and robustness, which
    is further confirmed by its transferability to a lowerresistivity DX54D cover

  text: Manufacturing tolerances have a measurable influence on the structural integrity
    of self-piercing riveted (SPR) joints in automotive applications, yet their quantitative
    impact on load-bearing behavior remains insufficiently resolved. This study establishes
    a validated hierarchical methodology to predict tolerance-dependent failure behavior
    of SPR joints, progressing from coupon to sub-component scale through an integrated
    experimental–numerical approach. Five critical manufacturing tolerances, including
    rivet length (±0.5 mm), rivet head position (±0.3 mm), orthogonality deviation
    (2.8° and 5°), lateral offset (up to 1.2 mm), and flange overlap reduction (up
    to 7.5 mm), were investigated. Steel–steel joints exhibited a higher sensitivity
    to tolerances by a factor of 2–3 compared to steel–aluminum joints. A unified
    effective rivet length concept was developed to consolidate the geometric effects
    of all tolerances into a single physically meaningful parameter, enabling load-bearing
    capacity prediction with R2 > 0.95 across all evaluated loading directions. The
    sub-component validation employing T-joint specimens indicates a 2–3 fold amplification
    of tolerance effects at critical structural regions, providing experimental evidence
    for the hierarchical scaling principle. The methodology was implemented in a tolerance-dependent
    CONSTRAINED_SPR3 formulation, providing >99 % computational efficiency improvement
    while maintaining a deviation in maximum force prediction within ±7 %. This framework
    enables the physically consistent representation of manufacturing variation within
    large-scale simulations and establishes a transferable basis for tolerance-resilient
    virtual vehicle development.

  text: Room-temperature lasing is a key milestone in the development of miniaturized
    optoelectronic and photonic devices. We present a simple approach to synthesize
    phase-pure quasi-2D layered tin perovskite nanowires with varying quantum well
    thicknesses (n = 1 to 4). By incorporating a new organic spacer capable of forming
    a hydrogen-bonded organic framework, this method promoted anisotropic crystal
    growth and enhanced lattice rigidity. Furthermore, introducing molecular intercalants
    enabled controlled crystallization into well-defined nanowires that function as
    Fabry–Pérot cavities. Cavities made from n = 2 to 4 perovskites support efficient
    and robust near-infrared, room-temperature optically pumped lasing with the threshold
    as low as 75.8 μJ/cm2, cavity quality factor over 3000, and negligible degradation
    over 106 pulses. A cleaved coupled nanolaser was fabricated as a proof-of-concept
    device for photonic applications.

  text: We discretise a recently proposed new Lagrangian approach to optimal control
    problems with dynamics described by force-controlled Euler-Lagrange equations
    (Konopik et al., in Nonlinearity 38:11, 2025). The resulting discretisations are
    in the form of discrete Lagrangians. We show that the discrete necessary conditions
    for optimality obtained provide variational integrators for the continuous problem,
    akin to Karush-Kuhn-Tucker (KKT) conditions for standard direct approaches. This
    approach paves the way for the use of variational error analysis to derive the
    order of convergence of the resulting numerical schemes for both state and costate
    variables and to apply discrete Noether’s theorem to compute conserved quantities,
    distinguishing itself from existing geometric approaches. We show for a family
    of low-order discretisations that the resulting numerical schemes are ‘doubly-symplectic’,
    meaning they yield forced symplectic integrators for the underlying controlled
    mechanical system and overall symplectic integrators in the state-adjoint space.
    Multi-body dynamics examples are solved numerically using the new approach. In
    addition, the new approach is compared to standard direct approaches in terms
    of computational performance and error convergence. The results highlight the
    advantages of the new approach, namely, better performance and convergence behaviour
    of state and costate variables consistent with variational error analysis and
    automatic preservation of certain first integrals.

    \                   <jats:p>Age-related changes in brain signal complexity are
    associated with cognitive decline and reduced neural adaptivity in older adults.
    Exergaming offers a promising prophylactic intervention combining physical and
    cognitive training. The aim of the present study was to assess how exergaming
    alters the temporal trajectory of brain signal complexity at rest and during gameplay
    in older adults.</jats:p>\r\n                  </jats:sec>\r\n                  <jats:sec>\r\n
    \                   <jats:title>Methods</jats:title>\r\n                    <jats:p>Twenty-eight
    healthy older adults participated in a 4-week exergaming intervention. Electroencephalography
    was recorded using 64 electrodes at rest (pre- and post-intervention) and during
    exergaming (pre-, mid-, and post-intervention). Brain signal complexity was quantified
    using multiscale entropy across 64 time scales on preprocessed signals.</jats:p>\r\n
    \                 </jats:sec>\r\n                  <jats:sec>\r\n                    <jats:title>Results</jats:title>\r\n
    \                   <jats:p>Post-intervention resting-state analysis revealed
    significant reductions at fine and increases at coarse scales in frontal, central,
    and posterior entropy. During gameplay, entropy declined widespread by mid-intervention,
    particularly at coarse scales over frontal, central and temporal regions. From
    mid- to post-intervention, the decline narrowed leaving a net pre-to-post reduction
    concentrated at coarse scales in these regions.</jats:p>\r\n                  </jats:sec>\r\n
    \                 <jats:sec>\r\n                    <jats:title>Discussion</jats:title>\r\n
    \                   <jats:p>Resting-state changes indicated a shift toward a younger
    brain profile, characterized by a transition from age-related increases in local
    processing to enhanced distributed processing, which may potentially mitigate
    the rise in neural modularity associated with aging. During gameplay, brain signal
    complexity decreased in week 2, followed by a modest change by week 4, consistent
    with the framework in which complexity initially streamlines and then adjusts
    toward a task-specific optimum. These findings suggest that exergaming can beneficially
    modulate brain complexity in older adults, offering the potential to reduce age-related
    neural decline and support healthy brain aging.</jats:p>\r\n                  </jats:sec>"
