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.

To overcome thermal imbalance constraints, an innovative strategy leveraging plastic shell containment is proposed to elevate the 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 rapid fusion, effectively preventing expulsion. Experimental results demonstrate that while the reference constant-current schedule fails to maintain a process window under a 2 mm initial gap (IG) disturbance, the proposed strategy significantly enhances process stability. It increases the maximum expulsion-free heat input by 24 % (to 6338 J) under normal conditions and by 77 % (to 6482 J) under the IG condition. Crucially, the increased heat input drives nugget growth across all interfaces, achieving a penetration depth of 0.38 mm (48 % penetration ratio) in the low-carbon steel sheet under the gap condition.

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 study addresses the formation of “viscous fingering” instabilities in structural adhesive joints, which are induced by thermally driven relative displacements during the liquid phase of the adhesive. Using a component-like specimen “bridge specimen,” the dependency of this phenomenon on process temperature and structural stiffness (rivet distance) was characterized. Experimental results reveal that while the relative displacement scales cubically with the free buckling length, the resulting adhesive area reduction follows an exponential trend, leading to a loss of effective bond area of up to 79%, which significantly compromises the joint strength in automotive applications. To predict these process-induced defects, a thermo-chemo-viscoelastic-viscoplastic adhesive model implemented in LS-DYNA was applied. The model combines curing kinetics, viscoelastic relaxation, and pressure-dependent plasticity and features a geometric damage parameter (D) that captures the adhesive area reduction caused by viscous fingering as an exponential function of the accumulated normal strain in the liquid phase. This damage parameter, calibrated on base-specimen level, was transferred to the component geometry. The simulation demonstrated high predictive accuracy with a maximum deviation of the adhesive area reduction of 3.1% compared to experimental data.

This research introduces a multilayer synchronous polarization projection method that fundamentally increases the DoF for polarization multiplexing. The DoF equals twice the number of projection layers. We experimentally demonstrate six- channel polarization multiplexing holography without position multiplexing. The six-channel multiplexing results indicate that our approach exceeds the conventional polarization multiplexing method, yielding an average 3.79 dB improvement in extinction ratio across the six channels. Compared with the theoretical limit of traditional polarization multiplexing, our method reduces crosstalk by an average of 6.52 dB across all channels in a seven-channel design.

However, responsibility is a complex normative and social phenomenon that we unfold in this chapter. We consider that the classical concepts of agency and responsibility do not fully capture what is needed for meaningful collaboration between human users and XAI. Advocating the perspective of sXAI, we argue that the growing adaptivity of AI systems will result in sXAI being considered as partners. Both partners adopt particular (dialogical) roles within a collaborative process and take responsibility for them. We expect that these roles lead to reactive attitudes toward the sXAI on the side of the human partners that make these roles relational. They resemble those reactive attitudes that we hold toward other human agents. For agents to exercise their responsibility, they need to possess agential capacities to fulfill their role with respect to the structure of a social interaction. Hence, sXAI can be expected to act responsibly. But because of XAI’s limited normative capacities, it might rather act as a marginal agent. We refer to marginal agents and show they can be scaffolded with regard to their agential capacities and their knowledge about the structure of a social interaction. The structure links the actions of the partners to each other in terms of a set of stimuli and responses to it in pursuit of a particular goal. Hence, it is important to differentiate between the different goals that a structure can impose for exercising responsibility. Therefore, we follow (Responsibility from the margins. Oxford University Press; 2015. https://doi.org/10.1093/acprof:oso/9780198715672.24001.0001 ) and offer three structures that can help to organize responsibility for decisions made with the assistance of AI systems.

Hereby, we call for a shift in perspective: from fair AI to tasking AI fairly . To motivate our vulnerability approach, we review the “Dutch welfare fraud scandal” (system risk indication—SyRI) and current challenges in the field of fair AI/machine learning (ML). Vulnerability of a person or members of a definable group of persons is a complex relational notion, and not a technical property of a technical system. Accordingly, we suggest several nontechnical strategies that hold the promise to compensate for the insufficiency of purely technical approaches to fairness and other ethical issues in the practical use of AI-based systems. To discuss how sXAI, due to its interactive and adaptive social character, might better fulfill this role than current XAI techniques, we provide a toy scenario for how sXAI might support the virtuous AI practitioner in an ethical inquiry.

We see a particularly positive potential in the social character of sXAI, which lies in the fact that skillful users, including those with “healthy distrust,” can use the adaptivity of sXAI to produce an explanation that is actually relevant and adequate for them. However, this requires a high level of skills on the part of the user and is thus in contrast to the general promise of efficiency in the use of AI.
