text: In diesem Forschungsprojekt wurde ein Messverfahren zur Bestimmung akustischer
Materialparameter von Polymeren im Ultraschallfrequenzbereich entwickelt. Das
Verfahrens sollte, die üblichen standardisierten Prüfmethoden erweitern, die bislang
primär im quasistatischen oder niederfrequenten Bereich eingesetzt wurden. Im
Gegensatz zu bestehenden Verfahren wie dem Zeitstandversuch oder der Dynamisch
Mechanischen Analyse (DMA) nach [DIN6721] sollte die neue Methode eine nicht-invasive
Charakterisierung der (visko-)elastischen Materialparameter im Frequenzbereich
von 0,75 MHz bis 2,5 MHz ermöglichen. Das entwickelte Ultraschallmesssystem arbeitet
nach dem Puls Echo-Prinzip und kann eine räumlich segmentierte, ringförmige Anregung
erzeugen. Die Bestimmung der frequenzabhängigen Materialparameter geschieht hierbei
über ein inverses Verfahren. Die Ergebnisse des Projekts zeigen, dass die Segmentierung
der Anregung, die Geometrie der Probe sowie das Puls-Echo-Messprinzip die Messergebnisse
sowie die Sensitivität gegenüber Scherparametern wesentlich beeinflussen. Im Rahmen
des Projektes wurde auch eine statistische Auswertung des Optimierungsverfahrens
hinsichtlich transversal-isotroper Materialsymmetrie mit Rayleigh-Dämpfung durchgeführt.
Die Ergebnisse zeigen, dass das entwickelte Verfahren gute Konvergenzeigenschaften
aufweist und sich durch verbesserte Robustheit auszeichnet.

text: This research project involved developing a measurement method to determine
the acoustic material parameters of polymers within the ultrasonic frequency range.
The aim of this method is to extend the range of standardised tests that operate
in the quasi-static or low-frequency range. In contrast to existing methods such
as the creep test or dynamic mechanical analysis according to [DIN6721], the developed
method is capable of non-invasive characterisation of the (visco-)elastic material
parameters in the frequency range of 0,75 MHz bis 2,5 MHz. The developed ultrasonic
measurement setup utilises the pulse-echo principle and can generate a spatially
segmented, ring-shaped excitation. The frequency-dependent material parameters
are determined using an inverse method. The final results of the project show
that the segmentation of the excitation, the geometry of the specimen and the
pulse-echo measurement principle have a significant influence on the measurement
results and the sensitivity to shear movements. As part of the project, a statistical
evaluation of the optimisation process was also carried out with regard to transversely
isotropic material symmetry with Rayleigh damping. The results show that the developed
process has good convergence properties and is characterised by improved robustness.

text: "Beamsplitters represent fundamental components in both classical and quantum
optical systems, enabling the distribution of light, as well as the generation
of interference, superposition, and entanglement. However, optical networks constructed
from conventional bulk 2 × 2-beamsplitters encounter inherent scalability issues,
as the number of required beamsplitters scales quadratically with the number of
optical modes for a fully connected network. Metasurfaces offer a promising route
to\r\novercome these constraints. By manipulating light at the wavelength scale,
compact optical components with advanced functionalities can be constructed, which
address several modes simultaneously. In this work, we design and experimentally
utilize a metasurface as a multiport beamsplitter. Furthermore, we realized a
multimode interferometer composed of two cascaded metasurfaces. We characterize
the individual and cascaded metasurfaces by using classical light, showing controllable
splitting ratios through tunable phase relations. We then expand the approach
to quantum light, employing single photons to demonstrate second- and third-order
photon correlations as well as single photon interference across multiple spatial
paths. These results establish metasurface-based multiport beamsplitters as a
scalable and reconfigurable platform bridging classical and quantum photonics. "

text: Metasurfaces are powerful tools for manipulating light using small structures
on the nanoscale. In most metasurfaces, near-field couplings are treated as being
unfavorable perturbations. Here, we experimentally investigate a structure consisting
of sinusoidally modulated silicon waveguides where near-field coupling of local
resonances leads to negative coupling, i.e., a negative coupling constant. This
gives rise to wave-vector-dependent eigenstates of elliptical, linear, and circular
polarizations. In particular, fully circular polarization states are not only
present at a single point in momentum space (k-space) but also along a line. This
circular polarization line, as well as a linear polarization line, emanates from
a polarization degeneracy at the Dirac point. We experimentally validate the existence
of these eigenstates and demonstrate the energy-, polarization-, and wave vector
dependence of this metasurface as well as its sensitivity to fabrication tolerances.
By tuning the incident k-vector, certain polarization-energy eigenstates are strongly
reflected, allowing for uses in angle-tunable polarization filters and light sources.

text: 'Der eugenetische Roman ist als ein literarisches Genre zu begreifen, das
biowissenschaftliche, bioethische und biopoetische Dimensionen miteinander verbindet,
um Grenzen und Konstanten des Mensch(lich)en auszuhandeln. Mindestens seit Darwin
und Galton sind die Modifizierung des menschlichen Individuums und die Optimierung
der menschlichen Spezies diskutiert worden, spätestens seit den 1980er Jahren
haben humangenetische und biotechnologische Entwicklungen den Diskurs neu perspektiviert.
Literatur trägt zu diesem Diskurs bei, indem sie Erprobungs- und Reflexionsräume
schafft: Sie modelliert menschliche Subjekte, die in eugenetische Zukunftsszenarien
eingeschrieben sind, und entwickelt spezifische Erzählweisen, die diese Subjekte,
ihre Lebensweisen und ihr Lebenswissen, narrativ erfahrbar machen. Fünf eugenetische
Romane der englisch- und deutschsprachigen Gegenwartsliteratur werden in der Studie
hinsichtlich Subjektmodellierungen und Narrationsweisen im Kontext der Eugenetik
untersucht.'

text: "We present an extremely simple polynomial-space exponential-time\r\n$(1-\\varepsilon)$-approximation
algorithm for MAX-k-SAT that is (slightly)\r\nfaster than the previous known polynomial-space
$(1-\\varepsilon)$-approximation\r\nalgorithms by Hirsch (Discrete Applied Mathematics,
2003) and Escoffier,\r\nPaschos and Tourniaire (Theoretical Computer Science,
2014). Our algorithm\r\nrepeatedly samples an assignment uniformly at random until
finding an\r\nassignment that satisfies a large enough fraction of clauses. Surprisingly,
we\r\ncan show the efficiency of this simpler approach by proving that in any\r\ninstance
of MAX-k-SAT (or more generally any instance of MAXCSP), an\r\nexponential number
of assignments satisfy a fraction of clauses close to the\r\noptimal value."

text: "Abstract\r\n \r\n Risk
is an integral part of modern societies and therefore school education, and in
particular mathematics education, should develop students’ risk literacy. Students’
risk literacy is part of the interdisciplinary research project siMINT (Understanding
complex STEM topics: Using simulations to promote competences for the 21st century).
One first challenge in this project was to find a common ground for the inconsistently
conceptualised terms of risk and risk literacy. Consequently, the aim of this
paper is to contribute to the conceptualisation of risk and risk literacy. The
first part of this paper provides a literature review on these areas, resulting
in a working conceptualisation of the two concepts. We further carried out two
consecutive steps of a Delphi study with\r\n N\r\n
\ = 15 and\r\n N\r\n
\ = 12 experts respectively, to develop a common conceptualisation
based on the plurality of different dimensions and elements of risk and risk literacy.
Based on the results of the first step of the Delphi study, we modified our working
conceptualisation, using a common model of risk and risk literacy with different
dimensions. In the second step of the Delphi study, the experts comment on (i) the
dimensions and (ii) the elements of risk and risk literacy in these dimensions.
The results showed that the experts are able to locate their individual definitions
of risk in the model with three dimensions (relation between risk/uncertainty,
connotation, and mathematical object) that we developed and to formulate reasons
for their allocation. Furthermore, the results revealed that risk literacy consists
of subsets of mathematical and non-mathematical elements that the experts rate
differently with regard to their importance. In general, the results contribute
to clarifying the constructs of risk and risk literacy as a basis for developing
approaches to improve risk literacy.\r\n "

text: "\r\n There is a contradiction between seven meta-analyses,
all of which indicate a substantial benefit of the flipped classroom (FC) method
for K-12 teaching and some larger study that found no such benefit when compared
to “traditional” teaching. In the theoretical part of the paper, we shed light
on this contradiction by consulting general literature on meta-analyses. Ranking
the 50 included FC studies by the number of classes per experimental condition,
we found a negative correlation between the “size” of a study and the effect in
favor of FC. In the empirical part, we present an FC study with three conditions
concerning mathematical teaching, based on\r\n n\r\n
\ = 950 students aged 11–13, in which many relevant covariates
(e.g., quality of instruction) were addressed. One FC condition was based on students’
knowledge acquisition through instructional videos at home (FCn:\r\n n\r\n
\ = 12 classes). Considering that self-regulation support might
play a crucial role especially for young students working at home, another FC
condition (FCS:\r\n n\r\n = 12
classes) was implemented, in which students could learn additional math-free strategies
concerning watching instructional videos. Both FC-conditions were experimentally
compared with a control group of traditional teaching (TT:\r\n n\r\n
\ = 13 classes). No significant effect on learning gains was
found between FCn and TT, indicating that “flipping” alone may not be more effective
per se. However, a significant difference was found between FCS and FCn. Thus,
supporting students’ self-regulation in addition may in indeed open the door to
successful FC, even with very young students.\r\n "

text: "Classical shadows are succinct classical representations of quantum states\r\nwhich
allow one to encode a set of properties P of a quantum state rho, while\r\nonly
requiring measurements on logarithmically many copies of rho in the size\r\nof
P. In this work, we initiate the study of verification of classical shadows,\r\ndenoted
classical shadow validity (CSV), from the perspective of computational\r\ncomplexity,
which asks: Given a classical shadow S, how hard is it to verify\r\nthat S predicts
the measurement statistics of a quantum state? We show that\r\neven for the elegantly
simple classical shadow protocol of [Huang, Kueng,\r\nPreskill, Nature Physics
2020] utilizing local Clifford measurements, CSV is\r\nQMA-complete. This hardness
continues to hold for the high-dimensional\r\nextension of said protocol due to
[Mao, Yi, and Zhu, PRL 2025]. Among other\r\nresults, we also show that CSV for
exponentially many observables is complete\r\nfor a quantum generalization of
the second level of the polynomial hierarchy,\r\nyielding the first natural complete
problem for such a class."

text: Service research has evolved into an interdisciplinary research field that
bridges diverse disciplines, including information systems (IS) and marketing.
Nearly two decades ago, the service system concept was introduced as a foundational
abstraction in service research, drawing on ideas from the service-dominant logic
(S-D logic) of marketing. Despite its widespread adoption in service research,
particularly in the IS discipline, the service system concept lacks a solid theoretical
foundation. This has resulted in conceptual ambiguity and overlap with related
constructs, such as service ecosystems. Moreover, it has largely remained a static
analytical lens, insufficiently capturing dynamic service phenomena, including
value co-creation and co-destruction, as well as the emergence of institutional
arrangements. To address these limitations, we propose Luhmann’s systems theory
(LST) as a robust framework for conceptualizing service systems as autopoietic
(self-creating) systems, in which communication serves as the fundamental mechanism
that drives value co-creation. We derive five theoretical propositions from this
re-conceptualization that clarify conceptual ambiguity and allow researchers to
explore dynamic service phenomena in greater depth. Given LST’s general approach,
our conceptualization provides a theoretically grounded, interdisciplinary foundation
for advancing service research.

text: Clinched joints with non-rotationally symmetric geometries exhibit
orientation-dependent mechanical behavior that is commonly neglected in structural-scale
simulations. Reuleaux triangle shaped clinched joints, in particular, show pronounced
in-plane anisotropy depending on their orientation. While such effects have been
studied at joint and specimen scale, their relevance at the structural level remains
largely unexplored. In this work, the influence of joint orientation on the bending
response of a joined structure is investigated using numerical simulations. A
simplified joint replacement model based on the *CONSTRAINED_SPR2 point-connector
formulation in LS-DYNA is employed, with parameters calibrated from previously
obtained experimental force displacement data. A hat shaped profile structure
subjected to three-point bending is analyzed in a parametric study considering
variations in joint orientation, joint spacing, and profile geometry. The results
show that joint orientation has little influence during the initial deformation
phase but becomes increasingly significant at larger displacements, where joint
behavior governs load transfer. Orientation dependent effects are found to influence
the global force displacement response and local load redistribution among joints,
with magnitudes comparable to those induced by changes in joint spacing and structural
geometry. The findings confirm that joint orientation effects remain relevant
at the structural level and should be considered in the design of structures assembled
using non-rotationally symmetric clinched joints.

text: In recent years, nanostructures assembled by DNA have found promising
applications in optics, medicine, and sensing. DNA origami in particular provides
unique self‐assembly properties, not only enabling a vast variety of functionalization
schemes but also presenting a promising route to fabricate large‐scale, bottom‐up
nanostructured arrays. This approach has comparable precision to electron beam
lithography but avoids slow and expensive patterning steps. However, self‐assembly
of lattices with high order and well‐defined periodicity requires careful tuning
of the deposition parameters and interactions involved, which has been done mostly
on mica so far. As mica is not compatible with standard microfabrication processes,
we investigate here the assembly of DNA origami lattices on the most general microfabrication
material, that is, silicon wafers, which has turned out to be rather challenging.
We study how the forming of polycrystalline 2D‐fishnet‐type lattices is influenced
by different incubation conditions and strengths of the origami–origami and origami‐surface
interactions, with the aim to create large‐scale single‐crystalline lattices.
The lattices are characterized by atomic force microscopy and analyzed for precision
of formation, achievable domain size, and surface coverage of well‐formed lattices.
Thanks to the silicon substrate, these DNA origami lattices can be further combined
with traditional microfabrication processes to turn them, for example, into metamaterials
with novel optical properties.
