text: Efficient detection of near-infrared light at telecommunication wavelengths
remains a central challenge for GaAs-based photonic and optoelectronic devices
due to the absence of linear absorption below the bandgap. Here, we demonstrate
a hybrid nonlinear optoelectronic device that enhances the detection efficiency
of a (001)-oriented GaAs PIN photodiode under telecommunication-wavelength illumination,
where absorption is intrinsically limited to two-photon absorption (2PA). Our
approach relies on the integration of a transferred, nanopatterned 385 nm-thick
(111)-oriented GaAs nanofilm acting as an on-chip nonlinear frequency-conversion
layer. Elliptical GaAs nanoresonators are employed to enhance second-harmonic
generation (SHG) resonantly, converting incident 1550 nm radiation into above-bandgap
photons efficiently absorbed by the underlying diode. Spatially resolved current–voltage
measurements reveal a pronounced enhancement of the detector response in regions
covered by the nanoantennas. The device exhibits a low dark current, while the
metasurface-covered regions show the largest current response under 1560 nm excitation
compared to the bare GaAs(100) diode and the unstructured GaAs(111) film. These
results establish a direct functional link between dielectric metasurface–based
nonlinear frequency conversion and electrical photodetection, providing a viable
route toward integrated sub-bandgap detection schemes.

text: "Abstract\r\n The service
life of fatigue-loaded components that already contain manufacturing‑induced microcracks
is primarily governed by the direction and the rate of fatigue-crack growth. When
multiple loading components (e.g., tension, compression, shear) act simultaneously
but not in temporal synchrony, out‑of‑phase mixed‑mode conditions occur. Such
loadings are typical for automotive chassis parts and mechanically joined sheet‑metal
assemblies. For optimized design of structural components, the crack kinking angle
that occurs under mixed‑mode loading must be predicted as accurately as possible.
At present, however, this is still challenging for out‑of‑phase loading conditions.
To investigate the associated crack kinking behavior, a novel Compact‑Tension‑Shear‑Mini
(CTSM) specimen was developed, enabling controlled generation of plane out-of-phase
mixed-mode loading states. Experiments were performed under various combinations
of cyclic and static mode I and mode II load components and compared with the
analytical predictions of the Out-of-Phase Mixed-Mode (OMM) concept. The measured
crack kinking angles showed very good agreement with the predicted values, with
mean deviations of only a few degrees, demonstrating the validity and reproducibility
of the approach. These findings confirm the applicability of the OMM concept for
describing fatigue‑crack propagation under non‑proportional mixed‑mode loading
and provide a basis for fatigue‑life assessment of clinched joints and other cyclic
multi-axially loaded components."

text: Investigating crack growth in sheet metal originating from clinched
joints is a major part of predicting the service life of mechanically joined structures.
Clinching allows different materials to be joined together. A key task in this
context is to perform crack growth simulations in the vicinity of clinched joints
considering different load and environmental conditions. This requires formulaic
descriptions of the fatigue crack growth rate curves for the materials used. For
this purpose, fatigue crack growth rate curves for different R-ratios and temperatures
are determined experimentally. Generally, these fatigue crack growth rate curves
can be described very well using a novel two-part exponential approach for the
formulaic description of fatigue crack growth rate curves developed at Applied
Mechanics of Paderborn University (FAM). In this case, three parameters are sufficient
to describe the fatigue crack growth rate curves. For the material HCT590X, which
is frequently used in clinched joints, it is shown as an example how the parameters
vary with the R-ratio and the temperature. In addition, at high crack growth rates,
a significant rise in the fatigue crack growth rate curve sometimes occurs at
both low and high temperatures. To account for this feature, the two-part exponential
approach can be expanded to include a third part.

text: 'Tacit knowledge is particularly valuable in product engineering. Experiences
reside in minds of employees and are not systematically documented but could have
a significant influence on sustainable product engineering. Existing approaches
do not offer sufficient support for harnessing technical tacit knowledge regarding
sustainable product engineering. In this paper a three-step method is presented:
The method contains knowledge acquisition, requirements extraction und requirements
validation for quality assurance. Acquisition is performed by support artifacts
like interview guidelines. Extraction is supported by Artificial Intelligence,
converting statements into requirements. These requirements are validated using
a specific questionnaire. The developed approach is applied in a funded project
of the European Union (EU) with automotive industry partners. The method supports
product engineers to collect tacit knowledge from experienced employees, transform
unsystematic knowledge into standardized technical requirements and validate them.
Application of this method enables creation of validated requirements that can
be applied throughout the company and are not exclusively dependent on a single
employee.'

text: Manufacturing companies increasingly integrate the strive towards sustainability
into product engineering to reduce resource consumption and environmental impacts.
A substantial share of a product’s environmental performance is determined during
engineering. Early assessments rely on generic data, which is gradually replaced
by more concrete simulation and primary data as product maturity increases. The
effective use of engineering simulation models for Life Cycle Assessment (LCA)
therefore remains a central challenge under heterogeneous, distributed and rapidly
evolving data. This article presents a systematic review of product engineering
approaches for integrating simulation models into LCA. A seven-step research approach
is applied to identify, categorize and evaluate existing approaches across CAx
tools. Relevant simulation parameters for sustainability assessment, including
material properties, process descriptors, consumables and waste streams, are identified
and analyzed. Based on identified data characteristics, the potential of Data
Science and Artificial Intelligence methods for LCA data preparation is assessed.
A conceptual knowledge-graph-based decision support approach is derived to enable
structured integration, traceability and reuse of simulation data for sustainability
assessment. The approach is evaluated using criteria from literature. Structured
integration of simulation data improves early-stage data quality and supports
decision-making in sustainable product engineering.

text: Design for Assembly, Disassembly and Reassembly (DfADR) prepares for high
levels of material circularity in terms of repair and remanufacturing. The intention
of reassembling products and their part simplies that inspection and sorting need
to be integrated with value-conserving objectives. Further, disassembly and reassembly
require higher competence levels of workforce than assembly. To provide the required
information during engineering, a metadata model (MDM) is required that links
established product models to capability models. Since processes to be carried
out for realizing a product largely determine required employees’ capabilities,
the proposed approach uses the ADR process domain to connect product and capability
domains. The research is based on a systematic literature analysis to identify
existing approaches regarding MDMs of ADR processes. Based on the results, an
integrative MDM is developed that answers defined competence questions. The model
enables queries which support engineers by feedback on which skills are required
for a product. This builds up a basis to check whether required skills are available
in the manufacturing company, either early in product engineering or later in
ADR planning.

text: With a range of consumer devices available, augmented reality (AR) continues
to make its way into everyday life and is also increasingly used in professional
and sensitive contexts. Especially collaborative use cases, such as remote meetings
or maintenance, offer potential, but also move issues in the area of privacy and
security into focus. We conducted a scoping review to gain an overview of the
current situation and found a lack of clear standards, with most approaches focusing
on single protection features. Using the knowledge from the scoping review, we
set up and conducted expert interviews. They revealed that end-users are almost
completely dependent on developers or device manufacturers regarding their options
for protection. The interviews also showed that most developers put little focus
on privacy and security, often due to external constraints, such as employers
treating the topic as an “afterthought” and not budgeting enough time for it.
The experts suggested offering better software support to developers to enable
the inclusion of privacy and security with less overhead as a solution. It was
also suggested that a general rise in privacy and security awareness could improve
the overall situation.

text: This article examines the most frequently attributed statement of Jesus in
the Qur’an, namely, ‘God is my Lord and your Lord’ (Q 19:36; Q 43:64; Q 3:51;
Q 5:72; Q 5:117). It investigates the extent to which this formula is connected
to Jesus’s words to Mary Magdalene on Easter morning in John 20:17. The analysis
aims to show that the Qur’an critically engages with the Christian interpretive
tradition surrounding this statement as recorded in John’s Gospel and adapts it
– both contextually and verbally – within its own theological framework. As in
the Christian tradition, this Qur’anic engagement also generates a broader discourse
on the hermeneutics of scriptural interpretation.

text: In dieser Dissertation werden Aspekte von high-gain multimode SU(1,1) Interferometer
theoretisch untersucht. Dabei wird der Prozess der parametrischen Fluoreszenz
(PDC) mithilfe von Integro-Differentialgleichungen modelliert, welche die räumliche
Entwicklung der Ebene-Wellen-Operatoren beschreiben. Es wurde gezeigt, dass Supersensitivität
für die Phasenempfindlichkeit dieser Interferometer erreicht werden kann, sofern
die Beugung der PDC Strahlung kompensiert wird. Weiterhin führt eine Erhöhung
der parametrische Verstärkung und eine Reduktion der Schmidt-Zahl zu einer Verbesserung
der Phasenempfindlichkeit und einer Verkleinerung des Phasenbereiches, über den
die Supersensitivität erreicht werden kann. Basierend auf der Struktur der Schmidt-Moden
von SU(1,1) Interferometern wurde ein numerisches Aufbereitungsverfahren konstruiert,
welches die Messung der Stärke des Squeezing und Anti-Squeezing des Zustandes
ermöglicht, der durch den ersten Kristall des Interferometers erzeugt wird. Das
Verfahren wurde experimentell von Kooperationspartnern angewandt, wobei eine gute
Übereinstimmung mit der Theorie festgestellt wurde. Zuletzt wurden SU(1,1) Interferometer
mit Laguerre-Gauß-Moden als Pump-Strahlung für die Messung von Winkelverschiebungen
untersucht. Es zeigte sich, dass sich die quantenmechanisch bedingte Messunsicherheit
verbessert, wenn die parametrische Verstärkung oder die Indizes der Pump-Mode
erhöht werden. Das generelle Verhalten gleicht dem der Phasensensitivität.

text: In this thesis, several aspects of high-gain multimode SU(1,1) interferometers
are theoretically investigated, with the focus being on metrological applications.
The parametric down-conversion (PDC) process utilized in these interferometers
is theoretically described via integro-differential equations describing spatial
evolution of the plane-wave operators. It is shown that for the phase sensitivity
of these interferometers, supersensitivity can be reached provided that proper
diffraction compensation is applied. The phase sensitivity improves if the gain
is increased or if the number of effective modes is decreased. This comes at the
cost of the phase-region width over which supersensitivity can be reached. Based
on the Schmidt mode structure of SU(1,1) interferometers, a processing method
is constructed which allows for the experimental retrieval of the levels of squeezing
and anti-squeezing of the multimode state generated by the first PDC section of
an SU(1,1) interferometer. It is then applied experimentally by collaborators
and is found to be in good agreement with the theoretical predictions. Finally,
SU(1,1) interferometers pumped with Laguerre-Gaussian beams are analyzed in the
context of angular displacement measurements. As either the gain, the OAM index
or the radial index of the pump are increased, the measurement uncertainty is
decreased, ultimately allowing for supersensitive measurements. Generally, the
behavior is the same as for the phase sensitivity.

text: Due to their devastating consequences, so-called century floods attract significant
public attention and are therefore covered in nationwide media. In journalistic
reporting, numerous conceptual metaphors are used to conceptualise such extreme
weather events. This linguistic study investigates how the century flood that
occurred in southern Germany in late May and early June 2024 was metaphorically
conceptualised in nationwide online journalism by identifying patterns of metaphorical
conceptualisation. The analysis draws on the foundations of Conceptual Metaphor
Theory as proposed by Lakoff and Johnson (1980), refined through the graded distinction
of schematicity levels in conceptual structure proposed in Kövecses (2017, 2020,
2022) Extended Conceptual Metaphor Theory. Accordingly, metaphors are understood
as schematically distinguishable mappings of conceptual aspects from source to
target areas, through which particular actions are constituted. Adopting a mixed-methods
approach that integrates manual with (semi-)automatic analytical procedures, the
study reveals that the century flood is predominantly conceptualised through the
highly schematic metaphor ZEIT IST SUBSTANZ (›time is substance‹), the less schematic
metaphor NATURKATASTROPHEN SIND PERSONEN (›natural disasters are persons‹), and
a set of least schematic, elaborating metaphors, namely HOCHWASSER IST GEGNER
(›flood is an opponent‹), HOCHWASSER IST ZERSTÖRER (›flood is a destroyer‹) and
HOCHWASSER IST MÖRDER (›flood is a murderer‹). From an ecolinguistic perspective,
the study critically reflects on how these metaphorical conceptualisations obscure
human co-responsibility for the intensity of extreme flood events.

text: "We generalize intersection numbers for combinatorial designs to designs in
finite meet-semilattices satisfying suitable regularity conditions. While designs
in regular semilattices go back to Delsarte, our regularity assumptions are weaker
than his and need not give rise to an association scheme. In this framework, we
extend Mendelsohn's equations, prove a generalized Singleton bound with Steiner
systems as equality cases, and determine the block intersection distribution at
any block of a Steiner system. In particular, this distribution is independent
of the chosen block.\r\n Specializing to several classical semilattice families,
our results recover a number of well-known distributions in coding and design
theory. In the Hamming and the $q$-Hamming (or bilinear forms) schemes, they give
the local distance distributions of MDS and MRD codes, respectively. In the Johnson
and $q$-Johnson (or Graßmann) schemes, they reproduce the block intersection distribution
of classical and $q$-analog Steiner systems, equivalently the distance distribution
of diameter-perfect constant-weight codes and diameter-perfect constant-dimension
subspace codes. For the $q$-Johnson schemes, to the best of our knowledge, this
result is new. As a further illustration, we apply our theory to designs of perfect
matchings.\r\n Our approach provides a unified treatment of these cases in the
strongest form known in the literature, determining the distribution relative
to each individual block or codeword, without averaging and without linearity
or additivity assumptions. Moreover, it identifies the natural double-counting
objects underlying these distributions, leading to formulas in the regularity
parameters of the semilattice and avoiding the more cumbersome expressions that
arise in eigenvalue-based approaches via the ambient association scheme."
