text: When humans interact with artificial intelligence (AI), one desideratum is
appropriate trust. Typically, appropriate trust encompasses that humans trust
AI except for instances in which they either explicitly notice AI errors or are
suspicious that errors could be present. So far, appropriate trust or related
notions have mainly been investigated by assessing trust and reliance. In this
contribution, we argue that these assessments are insufficient to measure the
complex aim of appropriate trust and the related notion of healthy distrust. We
introduce and test the perspective of covert visual attention as an additional
indicator for appropriate trust and draw conceptual connections to the notion
of healthy distrust. To test the validity of our conceptualization, we formalize
visual attention using the Theory of Visual Attention and measure its properties
that are potentially relevant to appropriate trust and healthy distrust in an
image classification task. Based on temporal-order judgment performance, we estimate
participants' attentional capacity and attentional weight toward correct and incorrect
mock-up AI classifications. We observe that misclassifications reduce attentional
capacity compared to correct classifications. However, our results do not indicate
that this reduction is beneficial for a subsequent judgment of the classifications.
The attentional weighting is not affected by the classifications' correctness
but by the difficulty of categorizing the stimuli themselves. We discuss these
results, their implications, and the limited potential for using visual attention
as an indicator of appropriate trust and healthy distrust.

text: The joining of dissimilar materials, such as steel and aluminum, entails significant
challenges during thermal curing processes due to differing coefficients of thermal
expansion. 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 validates
the model’s capability to predict manufacturing-induced damage in complex hybrid
structures solely based on thermal boundary conditions.

text: Several early music projects, such as the Stanford Josquin Project, have demonstrated
the potential for attaining valuable new musicological insights using a corpus-based
approach. However, the available musical corpora tend to be relatively small and
exhibit considerable variation in encoding practices. Aspiring corpus researchers
are confronted with a lack of suitable data, which needs to be addressed before
they can embark on their proper research. The EarlyMuse Short Term Scientific
Mission CORSICA has surveyed the current state of corpus creation and digital
editing in early music. Based on this information, it has developed a vision for
the future of corpus building in this field, which aims to speed up the production
of digital encodings while respecting the autonomy of the encoders and acknowledging
their efforts. This is important because much high-quality encoding is carried
out outside the field of professional musicology, and engaging citizen scientists
could help address the current shortage of research data. The CORSICA team‘s vision
is informed not only by a study of the available data, standards and technologies,
but also by Human-Computer Interaction, placing human goals and values before
the creation of technology and work processes. The core of the vision is that
successful corpus creation must be an inclusive endeavour in terms of both technology
and human participation. The report concludes with an implementation plan outlining
the initial steps required to realise the vision.

text: "Due to the application of Artificial Intelligence (AI) in high-risk domains
like law or medicine,\r\ntrustworthy AI and trust in AI are of increasing scientific
and public relevance. A typical conception,\r\nfor example in the context of medical
diagnosis, is that a knowledgeable user receives AIgenerated\r\nclassification
as advice. Research to improve such interactions often aims to foster the\r\nuser’s
trust, which in turn should improve the combined human-AI performance. Given that
AI\r\nmodels can err, we argue that the possibility to critically review, thus
to distrust, an AI decision is\r\nan equally interesting target of research.\r\nWe
created two image classification scenarios in which the participants received
mock-up\r\nAI advice. The quality of the advice decreases for a phase of the experiment.
We studied the\r\ntask performance, trust and distrust of the participants, and
tested whether an instruction to\r\nremain skeptical and review each piece of
advice led to a better performance compared to a\r\nneutral condition. Our results
indicate that this instruction does not improve but rather worsens\r\nthe participants’
performance. Repeated single-item self-report of trust and distrust shows an\r\nincrease
in trust and a decrease in distrust after the drop in the AI’s classification
quality, with no\r\ndifference between the two instructions. Furthermore, via
a Bayesian Signal Detection Theory\r\nanalysis, we provide a procedure to assess
appropriate reliance in detail, by quantifying whether\r\nthe problems of under-
and over-reliance have been mitigated. We discuss implications of our\r\nresults
for the usage of disclaimers before interacting with AI, as prominently used in
current\r\nLLM-based chatbots, and for trust and distrust research."

text: Fibre-reinforced polymers are increasingly used due to their high specific
strength, making them suitable for local sheet metal reinforcement. This allows
improved overall mechanical properties with reduced wall thickness of the sheet
metal part and, thus, lower weight of the components. One of the main focuses
of research into such hybrid structures is on the adhesive properties and the
respective failure behaviour of the interfaces. Generally, the failure behaviour
under the influence of mechanical loads can be divided into adhesive, cohesive
and mixed-mode failure. The correlation between observed failure behaviour and
adhesion properties of the hybrid composite materials is analysed in detail in
this work. The hybrid composite consists of an aluminium sheet of the alloy EN
AW‑6082 T6 and thermoset carbon fibre-reinforced plastic (CFRP) prepreg. The aluminium
sheet was laser pretreated before hybrid production to improve the adhesion properties.
The specimens studied were produced by the prepreg pressing process, in which
the components are cured and joined simultaneously. The influences of the thickness
of the CFRP part, the layup, the fibre orientation at the boundary layer, and
the laser pretreatment parameters on the properties of the hybrid joints were
investigated.

text: This paper investigates two modeling approaches for the simulation of the
deformation and decomposition behavior of preconsolidated rovings above the thermoplastic
matrix{\textquoteright} melting temperature. This is crucial for capturing the
local material structure after processes introducing highly localized deformation
such as mechanical joining processes between metal and fiber reinforced thermoplastics
(FRTP). A generic finite element (FE) model is developed, incorporating interfaces
discretized through either cohesive zone (CZ) elements or Coulomb friction-based
contacts. The material parameters for the FE elements are derived from the initial
stiffness of a statistical volume element (SVE) at micro scale modelled with an
Arbitrary-Lagrange-Eulerian method for three load cases. The CZ properties calculated
are based on the shear viscosity of the composite. The CZ and contact modelling
approaches are evaluated using three load cases of the SVE, comparing force-displacement
curves. Under simple loading conditions, such as normal pressure tension and bending,
both methods produce similar results; however, in complex load cases, the CZ approach
shows clear advantages in handling interface interactions and shows robust simulations.
The CZ approach thus presents a promising method for simulating roving decomposition
in FRTP-metal joining applications above the matrix{\textquoteright} melting temperature.

text: The use of continuous fiber-reinforced thermoplastics (FRTP) in automotive
industry increases due to their excellent material properties and possibility
of rapid processing. The scale spanning heterogeneity of their material structure
and its influence on the material behavior, however, presents significant challenges
for most joining technologies, such as self-piercing riveting (SPR). During mechanical
joining, the material structure is significantly altered within and around the
joining zone, heavily influencing the material behavior. A comprehensive understanding
of the underlying phenomena of material alteration during the SPR process is essential
as basis for validating numerical simulations. This study examines the material
structure at ten stages of a step-setting test of SPR with two FRTP sheets with
glass-fiber reinforcement. Utilizing X-ray computed tomography (CT), the damage
phenomena within different areas of the setting test are analyzed three-dimensionally
and key parameters are quantified. Dominating phenomena during the penetration
of the rivet into the laminate are fiber failure (FF), interfiber failure (IFF)
and fiber bending, while delamination, fiber kinking and roving splitting are
also observed. At the final stages, the bottom layers of the second sheet collapse
and form a bulge into the cavity of the die.

text: Large Language Models (LLMs) excel in understanding, generating, and processing
human language, with growing adoption in process mining. Process mining relies
on event logs that capture explicit process knowledge; however, knowledge-intensive
processes (KIPs) in domains such as healthcare and product development depend
on tacit knowledge, which is often absent from event logs. To bridge this gap,
this study proposes a LLM-based framework for mobilizing tacit process knowledge
and enriching event logs. A proof-of-concept is demonstrated using a KIP-specific
LLM-driven conversational agent built on GPT-4o. The results indicate that LLMs
can capture tacit process knowledge through targeted queries and systematically
integrate it into event logs. This study presents a novel approach combining LLMs,
knowledge management, and process mining, advancing the understanding and management
of KIPs by enhancing knowledge accessibility and documentation.

text: "This study contributes to the evolving field of robot learning in interaction\r\nwith
humans, examining the impact of diverse input modalities on learning\r\noutcomes.
It introduces the concept of \"meta-modalities\" which encapsulate\r\nadditional
forms of feedback beyond the traditional preference and scalar\r\nfeedback mechanisms.
Unlike prior research that focused on individual\r\nmeta-modalities, this work
evaluates their combined effect on learning\r\noutcomes. Through a study with
human participants, we explore user preferences\r\nfor these modalities and their
impact on robot learning performance. Our\r\nfindings reveal that while individual
modalities are perceived differently,\r\ntheir combination significantly improves
learning behavior and usability. This\r\nresearch not only provides valuable insights
into the optimization of\r\nhuman-robot interactive task learning but also opens
new avenues for enhancing\r\nthe interactive freedom and scaffolding capabilities
provided to users in such\r\nsettings."

text: "Robot learning from humans has been proposed and researched for several decades
as a means to enable robots to learn new skills or\r\nadapt existing ones to new
situations. Recent advances in artificial intelligence, including learning approaches
like reinforcement\r\nlearning and architectures like transformers and foundation
models, combined with access to massive datasets, has created attractive\r\nopportunities
to apply those data-hungry techniques to this problem. We argue that the focus
on massive amounts of pre-collected\r\ndata, and the resulting learning paradigm,
where humans demonstrate and robots learn in isolation, is overshadowing a specialized\r\narea
of work we term Human-Interactive-Robot-Learning (HIRL). This paradigm, wherein
robots and humans interact during the\r\nlearning process, is at the intersection
of multiple fields (artificial intelligence, robotics, human-computer interaction,
design and others)\r\nand holds unique promise. Using HIRL, robots can achieve
greater sample efficiency (as humans can provide task knowledge through\r\ninteraction),
align with human preferences (as humans can guide the robot behavior towards their
expectations), and explore more\r\nmeaningfully and safely (as humans can utilize
domain knowledge to guide learning and prevent catastrophic failures). This can
result\r\nin robotic systems that can more quickly and easily adapt to new tasks
in human environments. The objective of this paper is to\r\nprovide a broad and
consistent overview of HIRL research and to guide researchers toward understanding
the scope of HIRL, and\r\ncurrent open or underexplored challenges related to
four themes — namely, human, robot learning, interaction, and broader context.\r\nThe
paper includes concrete use cases to illustrate the interaction between these
challenges and inspire further research according to\r\nbroad recommendations
and a call for action for the growing HIRL community"

text: "In light of growing demands for resource efficiency and sustainability in
vehicle engineering, the environmentally compatible separation of structural adhesive
joints is gaining increasing relevance. This study presents a comparative analysis
of two physically based debonding methods: the established hot-air process and
a cryogenic cold process based on liquid nitrogen (LN2). The primary objective
is to assess the ecological impact and process-related sustainability of both
approaches.\r\nExperimental investigations were conducted on a component-representative
triple-sheet structure that simulates common automotive flange joints. Thermal
input was applied either by convective heating using a hot air gun or by direct
cooling through a contact-based LN2 tool. The resulting temperature profiles were
recorded using spatially distributed thermocouples. Subsequently, the outer panel
was selectively debonded to replicate a repair scenario, and the mechanical integrity
of the remaining adhesive joint was evaluated through Mode I testing of L-shaped
specimens. Process data served as input for an Life Cycle Assessment (LCA) according
to DIN EN ISO 14040.\r\nThe cryogenic method achieved a 40% reduction in carbon
footprint compared to the hot-air process (0.337 kg vs. 0.559 kg CO2-equivalents),
primarily due to its shorter process time and more efficient heat transfer. While
the hot-air method’s impact is mainly driven by electrical energy use, that of
the cold method stems from cryogenic media consumption. Notwithstanding certain
disadvantages in specific impact categories, the LN2-based process exhibits a
superior overall ecological performance and signifies a promising solution for
repair- and recycling-oriented adhesive separation in structural vehicle applications."

text: Learning argumentative writing is challenging. Besides writing fundamentals
such as syntax and grammar, learners must select and arrange argument components
meaningfully to create high-quality essays. To support argumentative writing computationally,
one step is to mine the argumentative structure. When combined with automatic
essay scoring, interactions of the argumentative structure and quality scores
can be exploited for comprehensive writing support. Although studies have shown
the usefulness of using information about the argumentative structure for essay
scoring, no argument mining corpus with ground-truth essay quality annotations
has been published yet. Moreover, none of the existing corpora contain essays
written by school students specifically. To fill this research gap, we present
a German corpus of 1,320 essays from school students of two age groups. Each essay
has been manually annotated for argumentative structure and quality on multiple
levels of granularity. We propose baseline approaches to argument mining and essay
scoring, and we analyze interactions between both tasks, thereby laying the ground
for quality-oriented argumentative writing support.

text: Within the current energy and environmental crisis, new material- and energy-saving
processes are needed. For this reason, this study focuses on the development of
a new forming technology for Ti-6Al-4V sheet metal. It is based on combination
of solution treatment by resistive heating with rapid tool-based quenching and
subsequent annealing. This new “TISTRAQ” process is comparable with press-hardening
already known for steels and hot die quenching known for aluminium alloys. One
of the main influencing factors for this process is the heat transfer coefficient
(HTC). It is an important driver for adjustment of basic parameters, as selection
of tool material or the forming speed but also plays an important role while elaborating
temperature distribution in the numerical model. Therefore, a new and unique test
rig was developed to determine the HTC and to perform tool-based heat treatment
at specimen level under laboratory conditions. The test rig was used to investigate
the influence of the titanium-tool-lubricant system on HTC and cooling rate. Further
the effect of heat treatment in the test rig and tool-based quenching on microstructure
and mechanical properties was studied. To improve the prediction of the temperature
distribution of the titanium during cooling, the HTC was integrated into the numerical
process simulation

text: "The phase and TTT diagrams of the Ti-6Al-4V system allow the development
of a new forming process for a more energy- and materialefficient production of
sheet metal parts. This new “TISTRAQ” process is composed of two steps. In terms
of process technology, the first step is comparable to a direct press-hardening
process already well known for steels. In this step, the Ti-6Al-4V sheet material
is resistively heated to a temperature below β-transus Tβ and, after a very short
holding time, simultaneously formed and quenched by use of water cooled tools.
Thereby, the β phase undergoes a martensitic transformation. The second step is
a subsequent short-time annealing, which leads to a hardening of the material.
In this work, a new test rig using resistive heating technique was used in order
to produce\r\ndifferent solution treated and tool quenched (STQ) and subsequently
annealed (STA) states. In this paper, the effects of heating rate, solution treatment
temperature and holding time on microstructure and mechanical properties are addressed.
For the characterisation, tensile testing and scanning electron microscopy were
used. By the systematic variation of applied processing parameters, dominating
effects on microstructure and mechanical properties were evaluated. For example,
the solution treatment temperature was found to have a significant effect on microstructural
features and characteristic strength and strain values. The obtained results reveal
a high potential for future technical applications."

text: A detailed understanding of the cognitive process underlying diagnostic reasoning
in medical experts is currently lacking. While high-level theories like hypothetico-deductive
reasoning were proposed long ago, the inner workings of the step-by-step dynamics
within the mind remain unknown. We present a fully automated approach to elicit,
monitor, and record diagnostic reasoning processes at a fine-grained level. A
web-based user interface enables physicians to carry out a full diagnosis process
on a simulated patient, given as a pre-defined clinical vignette. By collecting
the physician’s information queries and hypothesis revisions, highly detailed
diagnostic reasoning trajectories are captured leading to a diagnosis and its
justification. Four expert epileptologists with a mean experience of 19 years
were recruited to evaluate the system and share their impressions in semi-structured
interviews. We find that the recorded trajectories validate proposed theories
on broader diagnostic reasoning, while also providing valuable additional details
extending previous findings.

text: Additive manufacturing (AM) technologies enable near-net-shape designs
and demand-oriented material usage, which significantly minimizes waste. This
points to a substantial opportunity for further optimization in material savings
and process design. The current study delves into the advancement of sustainable
manufacturing practices in the automotive industry, emphasizing the crucial role
of lightweight construction concepts and AM technologies in enhancing resource
efficiency and reducing greenhouse gas emissions. By exploring the integration
of novel AM techniques such as selective laser melting (SLM) and laser metal deposition
(LMD), the study aims to overcome existing limitations like slow build-up rates
and limited component resolution. The study’s core objective revolves around the
development and validation of a continuous process chain that synergizes different
AM routes. In the current study, the continuous process chain for DMG MORI Lasertec
65 3D’s LMD system and the DMG MORI Lasertec 30 3D’s was demonstrated using 316L
and 1.2709 steel materials. This integrated approach is designed to significantly
curtail process times and minimize component costs, thus suggesting an industry-oriented
process chain for future manufacturing paradigms. Additionally, the research investigates
the production and material behavior of components under varying manufacturing
processes, material combinations, and boundary layer materials. The culmination
of this study is the validation of the proposed process route through a technology
demonstrator, assessing its scalability and setting a benchmark for resource-efficient
manufacturing in the automotive sector.
