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: Der Beitrag beschäftigt sich mit der Frage, ob die Merkmale guter inklusiver
Schulen – verstanden als Schulentwicklungsinstrument – mit der Arbeitszufriedenheit
und den Selbstwirksamkeitsüberzeugungen von Lehrkräften in inklusiven Gesamt-
und Sekundarschulen zusammenhängen. Dazu werden Daten aus dem BMBF-geförderten
Projekt BiFoKi (Bielefelder Fortbildungskonzept zur Kooperation in inklusiven
Schulen) von N = 119 Lehrkräften analysiert. Die Ergebnisse zeigen, dass die Merkmale
guter inklusiver Schulen einen großen Teil der Varianz in der Arbeitszufriedenheit
aufklären. Die kollektive Selbstwirksamkeitsüberzeugung korreliert stark mit den
Merk-malen guter inklusiver Schulen und der Arbeitszufriedenheit der Lehrkräfte.
Für die individuelle inklusionsbezogene Selbstwirksamkeitsüberzeugung zeigen sich
itemspezifische Befunde, die diskutiert werden. Implikationen für die schulische
Praxis werden abgeleitet.

text: Models of Circular Economy introduce circularity strategies like reuse, repair
or remanufacture. A significant level of complexity is added when these strategies
are applied not only on integrated product level, but on lower levels of assemblies
and parts. Therefore, approaches, like Design for Assembly, Disassembly and Reassembly
(DfADR) become increasingly important including the consideration of ADR capabilities.
To put DfADR into practice, it is necessary to structure ADR-related product data
and make it usable for product engineers. For instance, assemblies resulting from
disassembly might not be consistent with original assembly structures. Therefore,
a Product Meta Data Model (MDM) is required to handle assembly-related data even
when it has extreme characteristics. A literature review on related MDMs reveals
a range of models for general product data and identifies a gap in consideration
of assembly-related data. In an expert workshop, requirements are raised to evaluate
existing models and develop ADR-related extensions. The MDM is conceptually modelled
and validated by competence questions. The paper presents an approach that makes
assembly-related data usable for hybrid decision support and enables engineers
to think ahead of ADR processes.

text: We examine the relation between voluntary audit and the cost of debt in private
firms. We use a sample of 7420 small private firms operating in the period 2006-2022
that are not subject to mandatory audits. Firms self-select into voluntary audits
because of the economic setting (e.g., ownership complexity, export, subsidiary
status) or because firm fundamentals limit their access to financial debt. In
the outcome analyses, we find that voluntary audits result in higher, rather than
lower, interest rates with increases ranging from approximately 1.7 percentage
points, but going higher depending on the exact specification. This effect is
present regardless of the perceived audit quality (Big-4 vs. non-Big-4), consistent
across auditor types. Audited firms’ earnings are less informative about future
operating performance. Voluntary audits facilitate access to financial debt for
high-risk firms. The price paid is reflected in higher interest rates for voluntary
audits – firms with higher information/fundamental risk.

text: We investigate the role of stakeholders in the CSR reporting of non-listed
savings banks in Germany. They are established by municipal trustees and serve
clients in their distinct operating area. Reporting discretion under the Non-Financial
Reporting Directive may lead to variation in CSR reporting due to differences
in sustainability interests of banks’ stakeholders and CSR governance (e.g. existence
of a CSR manager). We document that the CSR reports and specific CSR dimensions
are intensely associated with the existence of strong CSR governance and to a
lesser extent with the interests of municipal trustees and bank clients. However,
the associations with these stakeholders are predominantly present in banks with
strong CSR governance. Our findings inform policy discussions about detailed CSR
disclosure requirements (e.g. the European Sustainability Reporting Standards)
and extension of reporting scope to firms with regional orientation and absence
of typical shareholders.

text: Integrated photon-pair sources, providing scalability solutions, are crucial
for large-scale realizations of quantum photonic technologies. Their traditional
fabrication techniques, such as etching, are often complex, require long development
cycles, and are resource inefficient in case of fabrication imperfections or failures.
The two-photon polymerization (2PP) technique can offer a rapid, efficient, and
reproducible alternative for the fabrication of integrated photonic devices. Here,
we demonstrate an integrated photon-pair source based on a 2PP-defined strip-loaded
waveguide on a periodically poled thin-film lithium niobate (TFLN) platform. The
device generates photon pairs through type-II spontaneous parametric down-conversion
(SPDC), employing first-order quasi-phase matching (QPM) with TM-polarized excitation
light. The device achieves an on-chip pair generation rate of 4.357 MHz and a
coincidence-to-accidental ratio (CAR) of ∼404. To prove the flexibility and versatility
of the fabrication technique, the waveguides were erased from the LN substrate
and reprinted, reaching comparable performance. This work demonstrates the potential
of 2PP as a rapid production technique for high-performance integrated photon-pair
sources, offering a practical solution to the limitations of traditional fabrication
techniques and showcasing both reproducibility of the fabrication and the reusability
of the substrate.

text: "Many quantum optical applications in spectroscopy, communication and signal
analysis rely on spectrally-engineered nonlinear optical interactions to target
specific wavelengths or bandwidth. Here, in an established material platform like
lithium niobate the achievable wavelength and bandwidth combinations are usually
limited by the material’s dispersion and its birefringence. In this regard, mixed
crystals of lithium niobate tantalate (LNT) promise a novel material platform,
because they allow tuning the birefringence, which is central for type II phase
matching devices. Crucially, LNT offers crystal compositions without any birefringence,
which still retain their second-order optical nonlinearity. Despite recent progress
in the growth and fabrication of LNT, so far no works have investigated the unique
properties of LNT for use in electro-optics, nonlinear or quantum optics. In this
study, we explore nonlinear optical devices based on LNT for broad- and narrowband
nonlinear optical interactions based on recently measured Sellmeier coefficients.
Most interestingly, we find that compositions without birefringence allow the
design of broadband, degenerate type II phase matching sources spanning the whole
near- to mid-infrared range by only changing the poling period and pump wavelength.
Such devices are not easily realizable in pure lithium niobate or lithium tantalate.
This could potentially allow for\tmore flexible light sources and nonlinear devices
in quantum metrology, quantum spectroscopy and quantum communication."

text: Understanding and controlling the optical properties of lithium niobate tantalate
solid solutions (LiNb1−xTaxO3, 0 ≤ x ≤ 1) is essential for their use in integrated
quantum and nonlinear photonics. This material system allows for composition-dependent
tuning of key optical parameters such as refractive indices and birefringence.
While lithium niobate (LiNbO3, x = 0) and lithium tantalate (LiTaO3, x = 1) are
well characterized, reliable dispersion data for intermediate compositions remain
scarce, limiting accurate modeling and refractive index engineering. Here, we
address this gap by experimentally determining the ordinary and extraordinary
refractive indices of LiNb1−xTaxO3 over the spectral range of 405 − 1550 nm using
an interferometric technique. As a result, composition-dependent refractive index
dispersion and Sellmeier coefficients are derived and discussed in relation to
previous studies and structural aspects. In particular, a monotonic decrease of
the ordinary refractive index with increasing Tantalum concentration is observed.
The present Sellmeier coefficients further allow discussion of zero birefringence
dispersion and its composition dependence in lithium niobate tantalate.

text: "Eine zentrale Herausforderung in der Professionalisierung pädagogischer
Fach- und Lehrkräfte besteht in der Relation von eher theoretischen und praktischen
Ausbildungsbestandteilen. Beispielsweise fühlen sich angehende Lehrkräfte durch
ihr Studium häufig nicht ausreichend auf die beruflichen Anforderungen vorbereitet.
Daher wird verstärkt versucht, Curricula von Ausbildungs- und Studiengängen deutlicher
an den tatsächlichen professionellen Handlungsanforderungen zu orientieren und
auch in frühen Ausbildungsphasen verstärkt Elemente beruflicher Praxis zu integrieren.
\r\nDieser Band nimmt die Handlungsorientierung in der Ausbildung von Lehrkräften
und pädagogischen Fachkräften theoretisch-konzeptionell sowie empirisch in den
Blick. Zudem werden innovative Lehransätze aufgezeigt, die den Fokus auf eine
Stärkung einer solchen Handlungsorientierung legen, z.B. durch simulationsbasierte
Lern- und Prüfungsformate.\r\nEs handelt sich um den zweiten Band der Reihe Paderborner
Beiträge zur Bildungsforschung und Lehrkräftebildung, die von der PLAZ – Professional

text: 'Efficient thermal management in vehicles is becoming increasingly critical
due to stricter energy efficiency requirements and rising passenger expectations
for comfort. Conventional heating, ventilation, and air conditioning (HVAC) systems
rely on numerous air outlet temperature sensors, which add significant costs at
scale. This study introduces a hybrid virtual sensor concept that combines physics-based
mathematical modeling with data-driven methods to address this challenge. A detailed
physical model predicts air outlet temperatures, while neural networks capture
unmodeled heat exchanges and environmental disturbances. Two hybrid strategies
are explored: one augments the physical model with a neural network to learn residual
heat flows, and the other employs an adiabatic physical model enhanced by a neural
network that maps the total environmental heat exchange, supported by a disturbance
observer for accurate heat flow estimation. Evaluation using measurement data
from a real test vehicle in a simplified two-vent scenario demonstrates that hybrid
virtual sensors can provide reliable temperature estimates, reduce reliance on
hardware sensors, and maintain high control performance, highlighting the potential
of integrating physics-based and machine learning methods in vehicle climate control
systems.'

text: Flow forming of metastable austenites is an innovative, incremental
metal forming process with special capabilities due to the TRIP effect. However,
the TRIP effect during flow forming is significantly affected by disturbances
and especially batch fluctuations leading to process uncertainty. This aspect
is further analyzed and quantified in this paper to give insights on how to minimize
the impact of uncertainty. For this purpose, semifinished parts and resulting
flow forming workpieces are systemically characterized concerning their properties
and the property uncertainty supported by mathematical methods like correlation
analysis and error propagation. A result is that the most influencing impact factor
on the strain induced α’-martensite volume fraction as a material property are
batch fluctuations, specifically the variations of the chemical composition. Those
especially appear from batch to batch, but also within a batch accompanied by
e.g. temperature effects. To counter this challenge, different methods from control
theory like closed-loop property control and adaptive control can be applied to
flow forming. Thus, uncertainty will be reduced to increase process robustness
and to enable industrial exploitation of the TRIP effect in flow forming of metastable
austenitic steels.

text: Despite the pivotal role of tax legislation for the economy and society, empirical
research on how interest groups influence German tax legislation remains scarce.
This study addresses this gap by examining international corporate tax policy.
Based on 94 statements from eleven legislative procedures (2013- 2023), it analyzes
the factors determining whether demands from various interest groups during expert
hearings in the Finance Committee are adopted into final legislation. Methodologically,
the paper combines qualitative content analysis with a quantitative probit regression.
While descriptive data and initial analyses suggest varying success rates among
expert groups, these differences disappear when controlling for the specific direction
of the proposed changes. No significant group influence remains. The findings
suggest that in the later stages of the legislative process, lawmakers select
external expertise primarily based on substantive, technical criteria rather than
systematically favoring specific actors. Thus, the study contributes to the political
economy of taxation by highlighting the importance of technical content over pure
actor power.

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."
