text: "ABSTRACT\r\n This work
is concerned with the modeling of a cold‐box sand, a composition of sand grains
and a resin binder. To this end, experiments are performed, which show the following
characteristics: localization phenomena in the form of a shear band, softening
behavior in the force‐displacement curve, and asymmetric behavior for compression
and tension. To model this complex material behavior, a micromorphic continuum
is used. In the present contribution, we focus on the linear‐elastic regime and
demonstrate the identifiability of micromorphic material parameters under deliberately
induced inhomogeneous deformation states. In addition to the degrees of freedom
of a classical continuum, the micromorphic model has additional degrees of freedom,
introduced here in a phenomenological sense to represent kinematically enriched
deformation modes associated with the granular microstructure. Accordingly, the
micromorphic fields are not interpreted as a separate physical scale (e.g., “binder”
vs. “grains”), but as an effective continuum description at the specimen scale.
This contribution addresses parameter identification for a micromorphic model
of cold‐box sand, with a clear separation between homogeneous deformation states
governing classical elastic parameters and inhomogeneous states required to activate
and identify micromorphic length‐scale parameters. The main challenge lies in
identifying the micro material parameters. To determine these, the corresponding
gradient terms in the constitutive formulation must be triggered via properly
tuned experiments. Micro‐parameter identification is demonstrated using synthetic
data generated from a boundary‐value problem with inhomogeneous displacement fields.
The chosen benchmark enables controlled activation of gradient terms and thereby
renders optimization‐based identification of micromorphic parameters feasible.
The synthetic example is deliberately chosen to assess feasibility and identifiability
under controlled conditions, thereby isolating micromorphic identifiability aspects
from experimental uncertainties. The novelty of the contribution lies in explicitly
linking micromorphic parameter identifiability to kinematic inhomogeneity, and
in demonstrating this link within a tractable forward– inverse setting for a linear‐elastic
micromorphic continuum."

text: Information Systems (IS) is rooted in systems theory. Systems theory offers
powerful concepts to address challenges of growing system complexity and non-systemic
design approaches in information systems. Despite its systemic origins, systems
theory remains a peripheral topic in IS. The study addresses this gap by introducing
a comprehensive framework of 52 systems-theoretical concepts to guide the design
of complex IS artifacts. We synthesize scattered systems knowledge from diverse
disciplines to provide a unified level of abstraction for complex information
system design. We apply the framework to a use case of business reputation systems
to show how the systems lens informs the design of a novel, complex information
system. We make three key contributions to the literature. First, the framework
provides a common ground for interdisciplinary research in information system
design. Second, it offers a unified level of abstraction grounded in systems theory
that serves as a coherent basis for artifact design. Third, it demonstrates the
potential of systems theory as a foundational justificatory knowledge base. Furthermore,
we provide guidance on applying the framework across multiple modes of reasoning,
alongside further application guidelines. The study thus serves as a bridge between
the body of systems knowledge and contextual design in IS.

text: "Trust between client and consultant is perhaps the most important asset in
con-sulting, as this is a highly intangible knowledge-intensive business that
concerns is-sues of outstanding strategic and operational importance for the customers.
Cli-ents who have not worked with a particular consultancy face considerable risk
when they place an order while lacking reliable information about the service
quality they can expect. There is a strong link between trust and reputation,
as the positive reputation of a consultancy can act as a substitute for a new
client’s missing individual experience with the provider, fostering trust in the
service quali-ty. Thus, creating, maintaining, and demonstrating a good reputation
is of signifi-cant importance for consultancies in a very competitive industry.\r\nTo
facilitate trustworthy signals, we design and implement a novel reputation mechanism
that carries a monetary weight stored on a blockchain network as an immutable,
decentralized, and transparent ledger. Based on an implementation in the Ethereum
network and subsequent evaluation, we conclude that the reputation mechanism can
contribute to leveling information asymmetry and reducing risk while increasing
reputation and trust. The mechanism lends itself to being used in other business-to-business
scenarios that suffer from similar information asymmetries."

text: To reduce CO₂ emissions, the automotive industry is adopting multi-material
structures. Fusion-based joining reaches its limits for aluminium–steel due to
brittle intermetallic phases and mismatched thermophysical properties; therefore,
mechanical joining (e.g., SPR) is used. Though conventional SPR requires tool
changes for different stack-ups. Versatile self-piercing riveting (V-SPR) addresses
this with an extended punch actuator and a multi-range-capable rivet (Kappe in
PERD16:363–378, 2022), enabling joints up to 600 MPa across varying thicknesses
without retooling. With the use of ultra-high-strength steels up to 1000 MPa,
optimisation is required. This study quantifies how rivet shank geometry affects
joint formation using a design of experiments and validated 2D axisymmetric FE
simulations. The optimum depends strongly on the material system. For CP1000–EN
AW-6014, maximum interlock f is predicted for a medium shank thickness of about
0.73 mm, a small internal foot radius of 0.620 mm, and a deeper drill depth of
3.136 mm, yielding f fc =0.4503 mm with a desirability of 0.954. For EN AW-6014–EN
AW-6014, the optimum shifts to a thinner shank of 0.670 mm, a larger internal
foot radius of 0.820 mm and a shallow drill depth of 2.30 mm, giving ffc = 0.3023
mm with a desirability of 1.0. A compromise geometry of 0.713 mm shank thickness,
0.776 mm internal foot radius and 2.755 mm drill depth achieves ffc = 0.3641 mm
for CP1000–aluminium and ffc = 0.1851 mm for aluminium–aluminium with an overall
desirability D = 0.6378, expanding V-SPR to ultra-high-strength steel–aluminium
joints while maintaining aluminium joinability.

text: This study investigates the determinants of tax complexity in Indonesia, focusing
on the perspectives of tax officers and firms, and thus provides a case study
relevant to developing countries. Understanding tax complexity in this context
is crucial as developing nations frequently encounter legislative, fiscal, and
administrative challenges that exacerbate their tax complexity. Complexity can
hinder investment, impair tax revenue collection, and impede economic development.
The authors adapt a global survey instrument to the Indonesian context and collect
responses from Indonesian tax officers and firms. Transfer pricing is perceived
as the most complex tax regulation which is consistent with cross-country studies.
However, in contrast to the global findings, statutory tax rates and taxes on
dividends rank second and third in Indonesia. While Indonesian tax officers emphasize
the complexity of transfer pricing regulations, firms are more concerned about
the complexity of tax procedures, especially tax guidance and tax audits. Furthermore,
comparative analyses show that tax officers perceive tax regulations as being
more complex than tax procedures. In contrast, firms perceive the opposite, particularly
for tax audits. The findings offer a nuanced picture of tax complexity in a developing
country and provide guidance for tax reforms in Indonesia. They also serve as
a commencement for further analyses of developing countries.

text: Der Beitrag untersucht die Einführung von iPads im Musikunterricht
einer Sekundarschule aus einer soziomaterialen Perspektive. Auf der Grundlage
einer mehrjährigen Begleitung wird mit Verfahren der Situationsanalyse aufgezeigt,
wie die Digitaltechnologien – insbesondere die App GarageBand – in bestehende
Fachkulturen, Dingordnungen und Unterrichtsroutinen eingebettet werden. Die Analyse
offenbart, wie im Musikunterricht der Digitalisierungsprozess oft an alten Dingen,
vertrauten Routinen und fachimmanenten Ideologien, wie dem Klaviozentrismus und
einer Liveness-Norm, scheitert. Zugleich ergänzt ein alternatives Verständnis
unterrichtlichen Musiklernens das handwerkliche Reproduzieren und Selbstüberwinden
in Präsenzdarbietungen um die Klangarbeit beim explorativ-selbstständigen Erfinden
und Produzieren präziser Aufnahmen. Die Ergebnisse werden hinsichtlich der Debatten
um Digitalisierung in Schule und Musikunterricht diskutiert.

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: "Abstract\r\n The micropolar
continuum is a special case of a micromorphic material model and has additional
degrees of freedom in the form of microrotations compared to the classical continuum.
With the micropolar model, size effects can be considered and the boundary value
problem can be regularized when localization effects occur. In order to map the
microrotations, an additional strain measure and an additional stress are introduced.
For simulation of plasticity, it is possible to define one yield function, and
thus one plastic multiplier as well as one equivalent plastic strain occur. This
approach is known as the single-surface plasticity approach. The macro- and micro-stresses
are coupled in a common flow function. On the other hand, there is the so-called
double-surface plasticity when one yield function, one plastic multiplier, and
one equivalent plastic strain, respectively, are introduced for each of the macro-
and micro-variables. The coupling of the macro- and micro-variables is established
by a possible coupling of both yield functions. The purpose of this paper is to
compare both approaches and to identify similarities and differences."

text: "This paper presents a holistic framework for the transition from diesel to
electric bus networks,\r\ncrucial for meeting EU regulations targeting 100% zero-emission
urban buses by\r\n2035. We employ a two-phase solution framework: in phase 1,
we solve the Charging Location\r\nand Electric Vehicle Scheduling Problem to generate
vehicle schedules that are feasible\r\nfor electric operation; in phase 2, these
schedules serve as input to a multi-period transition\r\nplanning model that minimizes
the total cost of ownership while determining fleet\r\nreplacement and charging
infrastructure deployment. Our experiments show that schedules\r\nobtained from
solving the integrated charging location and vehicle scheduling problem\r\nsignificantly
outperform traditional methods, resulting in lower total cost of ownership. Additionally,\r\ntransition
plans reduce local emissions by up to 85% compared to a diesel-only\r\nscenario.
We find that vehicle rotations with long distances and sufficient idle time are\r\nprioritized
for electrification, enabling earlier emission reductions and cost savings. This\r\nhighlights
the importance of adopting vehicle scheduling tailored for electric buses, rather\r\nthan
relying on legacy diesel schedules."

text: "This paper deals with the development and results of a prediction framework
for traffic light control systems as well as the usage and benefits of such predictions
in green light optimal speed advisory (GLOSA) scenarios.\r\nVarious machine learning
methods like support vector machines, neural networks or reinforcement learning
were evaluated for their applicability in the prediction context and compared
based on their efficiency and most importantly accuracy. The resulting prediction
framework uses decision tree ensemble models combined with certain model knowledge
to forecast different control strategies. This method was chosen due to its best
performance in various test scenarios. Very high accuracy and fidelity were achieved
for standard control methods like fixed-time, time-of-day-based and 'ordinary'
traffic-based programs. Only for the more sophisticated model predictive control
which was tested lower accuracies were achieved.\r\nFor the upcoming GLOSA application
the penetration of equipped vehicles was varied for different traffic scenarios
and control strategies. Results showcase high potentials for enhancing urban mobility
and reducing environmental impact by lower emissions and waiting times. However,
it is also clear from the studies presented in this contribution that the coordination
of the control strategy with the GLOSA vehicles is of enormous importance."
