text: 'The widespread deployment of 5G networks, together with the coexistence of
4G/LTE networks, provides mobile devices a diverse set of candidate cells to connect
to. However, associating mobile devices to cells to maximize overall network performance,
a.k.a. cell (re)selection, remains a key challenge for mobile operators. Today,
cell (re)selection parameters are typically configured manually based on operator
experience and rarely adapted to dynamic network conditions. In this work, we
ask: Can an agent automatically learn and adapt cell (re)selection parameters
to consistently improve network performance? We present a reinforcement learning
(RL)-based framework called CellPilot that adaptively tunes cell (re)selection
parameters by learning spatiotemporal patterns of mobile network dynamics. Our
study with real-world data demonstrates that even a lightweight RL agent can outperform
conventional heuristic reconfigurations by up to 167%, while generalizing effectively
across different network scenarios. These results indicate that data-driven approaches
can significantly improve cell (re)selection configurations and enhance mobile
network performance.'

text: In this paper we generalize the geodesic flow on (finite) homogeneous graphs
to a multiparameter flow on compact quotients of Euclidean buildings. Then we
study the joint spectra of the associated transfer operators acting on suitable
Lipschitz spaces. The main result says that outside an arbitrarily small neighborhood
of zero in the set of spectral parameters the Taylor spectrum of the commuting
family of transfer operators is contained in the joint point spectrum.

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: "Abstract\r\n \r\n Background\r\n
\ Research on procrastination mostly focuses on person‐related
antecedents and neglects situational and social factors, such as group work. Prior
research indicates that conjunctive and additive group work may increase individual
effort and performance as compared to individual work.\r\n \r\n
\ \r\n Aims\r\n
\ Based on these findings, we investigate whether conjunctive
and additive group work may also help reduce procrastination as compared to individual
work.\r\n \r\n \r\n
\ Methods\r\n \r\n
\ In a registered field experiment,\r\n N\r\n
\ = 218 students with high levels of trait procrastination
worked on an academic task over the course of 10 days in one of three conditions
(individual work vs. conjunctive group work vs. additive group work). Dependent
variables comprised task procrastination, task performance, and positive and negative
task‐related affect.\r\n \r\n \r\n
\ \r\n Results\r\n
\ Regarding conjunctive group work, results are mixed,
with some evidence that conjunctive group work leads to lower procrastination
as compared to individual work. Both types of group work resulted in higher negative
task‐related affect when assessed prospectively. No other effects were found.\r\n
\ \r\n \r\n Conclusions\r\n
\ The findings contribute to the idea that targeted
changes in the learning environment, such as the implementation of group work,
may help reduce procrastination.\r\n "

text: 'In perovskite solar cells (PSCs), electron transport layers (ETLs) play an
important role in the selection and transport of electrons. Understanding the
properties of these layers in relation to device performance is essential for
optimizing solar cell efficiency and enabling their integration into emerging
architectures, such as flexible solar cells. Here, we deposited TiO2 at different
thicknesses using atomic layer deposition (ALD), a technique well-suited for producing
uniform and pinhole-free films. The crystal structure of the layers was controlled
by depositing the films at three different temperatures: 150 °C, 250 °C, and 350
°C. The layers were characterized in detail to determine the morphology (by atomic
force microscopy), surface composition (by X-ray photoelectron spectroscopy) and
the crystal structure (by X-ray diffraction). The TiO2 layers were then incorporated
as ETLs in planar perovskite solar cells to evaluate their influence on device
performance. Higher deposition temperatures led to improvements in device fill
factor and open-circuit voltage, leading to more efficient solar cells. Notably,
the best device performance for the ALD-TiO2 layers was achieved with films deposited
at 250 °C.'

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: 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.
