text: Abstract. Within the punch-bending process semi-finished products
of strip or wire material are formed and punched in several subsequent steps into
a finished product like brackets, mounts, contacts or spring elements. In the
context of those multi-stage straightening and bending processes, cross-stage
and quantity-dependent effects significantly leads to undesired component deviations.
To optimize the punch-bending process with regard to these component deviations
and thus the waste rate, the concept of a hybrid data-driven model is presented.
To automatically acquire and process this hybrid data while also enable the usage
by multiple clients, a digital twin has to be developed. In this paper the communication
infrastructure between the punch-bending system and the digital twin is presented,
using the Asset Administration Shell as specification. This automated communication
is validated using exemplary data from the punch-bending system.

text: Abstract. Flow forming is recognized for its precision in producing
rotationally symmetric components, but the use of metastable austenitic stainless
steel (AISI 304L) introduces challenges due to uncontrolled strain-induced α’
martensite formation. Variations in factors such as eccentricity and batch inconsistencies
lead to unpredictable microstructural profiles, limiting reproducibility [1,2].
This study addresses these issues by incorporating thermal actuators for cryogenic
cooling and induction heating to regulate forming temperatures, enabling control
of the α’-martensite content. Experimental investigations demonstrate that local
tempering during thermomechanical reverse flow forming produces discernible variations
in microstructure, affecting mechanical and magnetic properties [3]. Controlled
local adjustments of α’-martensite content allow for customization of properties
in seamless tubes, advancing manufacturing capabilities for complex, defect-free
components. The results presented demonstrate promising strategies for implementation
within the context of closed-loop property control in flow forming.

text: "Abstract\r\n This paper presents
a characterization of the microstructural evolution and its correlation with the
magnetic structure due to flow forming of semi-finished tubes of austenitic stainless
steel AISI 304L. The plastic deformation triggers a phase transformation of the
metastable austenite into α’-martensite.\r\n Depending
on the combination of production parameters, different fractions of strain-induced
α’-martensite were measured by means non-destructive micromagnetic techniques
and correlated with the evolution of hardness and the microstructure using electron
backscatter diffraction analyses. The magneto-optical Kerr effect analysis was
used as a tool to perform a qualitative analysis of the evolution of the magnetic
domain structure correlated with the formation of α’-martensite. An analysis of
these data allowed to derive surface magnetization hysteresis loops that were
compared with integral hysteresis loops of the specimens. It was proven by both
methods that the formation of martensite increases the magnetic energy and the
spontaneous magnetization of the specimens. The results of this investigation
contribute to a better understanding of micromagnetic sensors to monitor and control
the formation of α’-martensite in a flow forming. Furthermore, various techniques
have demonstrated the evolution of the magnetic properties of the material, which
can be applied in applications for invisible coding of workpieces."

text: Abstract. The incremental flow forming process features a large number
of process parameter combinations that can be varied from pass to pass or during
a pass. In the future however, a more efficient utilization of this large number
of process parameter combinations and a compensation of process disturbances could
be required. This is due to a rising demand for increasing the part complexity,
e.g. by graded property structures or a more complex geometry. In this context,
innovative approaches like closed-loop property control and optimal control are
advantageous, but require fast process models of flow forming that are not state
of the art. This paper thus proposes a new modelling approach of multi-pass flow
forming especially taking the transfer behavior between process parameters and
wall thickness evolution from pass to pass into focus. A hybrid modelling approach
is developed that combines knowledge about the incremental process character with
empirical data regression to a basic analytic relation. The basic relation is
further extended by a multi-layer neural network to enhance the overall model
accuracy. This hybrid modelling approach is finally validated using experimental
data. Thus, it is shown that a suitable model structure was found in context of
a future closed-loop control or optimal control for multi-pass flow forming.

text: "Zusammenfassung\r\n Die Eigenschaftsregelung
mit einer online-Messung der Bauteileigenschaften ist ein in der Umformtechnik
viel diskutiertes, aber kaum validiertes Konzept, um den Automatisierungsgrad
bei der Bauteilfertigung weiter zu erhöhen. Dieser Artikel soll helfen, die Lücke
beispielhaft für den Fertigungsprozess des Drückwalzens metastabiler Austenite
zu schließen. Der metastabile austenitische Edelstahl ändert hierbei während der
Verformung seinen α′-Martensitgehalt und damit verbunden die magnetischen Eigenschaften.
Deshalb soll über die Regelung das definierte Einstellen des α′-Martensitgehaltes
möglich werden. Im Rahmen des vorliegenden Artikels wird gezeigt, wie mittels
des modellbasierten Entwurfs die Eigenschaftsregelung ausgelegt und parametriert
werden kann. Zudem beinhaltet der Artikel experimentelle Validierungsergebnisse
der zuvor entworfenen Eigenschaftsregelung."

text: ' Zusammenfassung: Frühe mathematische Bildung, die ihren Ausgangspunkt
in den (Spiel-)Situationen der Kindertagesstätte nimmt, kann breite mathematische
Erfahrungen ermöglichen, wenn die (Spiel-)Situationen entsprechende Möglichkeiten
bieten. Erste Studien weisen darauf hin, dass in diesen Situationen verschiedene
mathematische Inhalte angesprochen werden können. Allerdings konzentrieren sich
bisherige Studien auf ausgewählte Kontexte oder Inhaltsbereiche. Diese Studie
zielt daher auf eine vertiefte Analyse der Gelegenheiten für mathematische Erfahrungen,
die in verschiedenen (Spiel-)Situationen im Alltag der Kindertagesstätte entstehen
können. Dazu wurde eine videobasierte Beobachtungsstudie mittels einer Action-Kamera
in einer Kindertagesstätte durchgeführt. Die Ergebnisse zeigen, dass eine Vielfalt
von mathematischen Inhalten in (Spiel-)Situationen in der Kindertagesstätte beobachtet
werden kann, einzelne Inhalte jedoch nur in formellen Lernsituationen auftreten.

text: 'Effective single-particle theories, such as Hartree–Fock, density functional
theory, and tight-binding, are limited by the computational cost of the self-consistent
field (SCF) procedure, which typically scales cubically with the system size.
This makes large-scale applications impractical without specialized algorithms
and hardware. Here, we present the submatrix and graphical processing unit (GPU)-accelerated
software implementation of the PTB tight-binding potential, realized in the open-source
ptb codebase [M. Mueller, A. Katbashev, and S. Ehlert (2025). “grimme-lab/ptb:
v3.8.1,” Zenodo. https://zenodo.org/records/17015872]. We first benchmark a traditional
diagonalization-based SCF solver against density-matrix-based purification approaches,
systematically varying both system size and computer hardware. Our findings show
that the usage of GPUs permits shifting the boundaries to much larger systems
than previously thought feasible, achieving an overall 10–15-fold performance
speedup. Second, we introduce the implementation of a decomposition-type submatrix
method, specifically designed for efficient operation on mid- to large-sized systems,
to address the computational overhead associated with full-system diagonalization.
We demonstrate that, from a certain dimension (≈104 basis functions) on, our submatrix
method reduces the overall computational cost while maintaining acceptable numerical
accuracy. Our study demonstrates the significance of the interplay between modern
hardware, algorithmic considerations, and novel tight-binding methods, paving
the way for further development in this direction.'

text: 'Selbstkonzepte werden als mentale Repräsentationen einer Person von sich
selbst definiert und stehen aufgrund ihrer Bedeutung für den Berufserfolg von
(angehenden) Lehrkräften im Fokus der Forschung zur Professionalisierung von Lehrkräften.
Ziel der vorliegenden Arbeit ist die de-taillierte Betrachtung der Ausprägungen
akademischer Selbstkonzepte von gewerblich-techni-schen Lehramtsstudierenden im
Master of Education zur Analyse der Struktur, Entwicklungsein-flüsse und Beziehungen
zwischen verschiedenen Dimensionen akademischer Selbstkonzepte anhand eines sequentiellen
Mixed-Methods-Designs. Dieses besteht aus einer quantitativen Studie (n=115),
angelehnt an das TPACK-Modell, und einer anschließenden qualitativen Inter-viewstudie
(n=18) angelehnt an das PCK-Modell. Es zeigt sich, dass akademische Selbstkonzepte
angehender Lehrkräfte anhand von Professionswissensmodellen strukturierbar sind.
Dies trifft sowohl auf die Strukturierung anhand des TPACK-Modells als auch anhand
des PCK-Modells zu. Als Entwicklungseinflüsse zeigen sich besonders Aspekte: praktische
Erfahrungen im schulischen sowie im fachwissenschaftlichen Bereich und auch die
Auswirkungen sozialer und dimensionaler Vergleichsprozesse. Bei den Auswirkungen
von Vergleichsprozessen fungiert jedoch die wahr-genommene Relevanz der jeweiligen
Dimensionen der akademischen Selbstkonzepte als Mode-rator. Abschließend werden
forschungsmethodische sowie hochschulbildungspraktische Im-plikationen der Ergebnisse
diskutiert.'

text: 'Self-concepts are defined as a person''s mental representations of themselves
and are often the focus of research on the professionalization of teachers due
to their importance for the profes-sional success of (pre-service) teachers. The
aim of this study is to take a detailed look at the characteristics of academic
self-concepts of pre-service technology teachers in their Master of Education
to analyze the structure, developmental influences and relationships between differ-ent
dimensions of academic self-concepts using a sequential mixed-methods design.
This con-sists of a quantitative study (n=115), based on the TPACK model, and
a subsequent qualitative interview study (n=18), based on the PCK model. First
of all, it is shown that academic self-con-cepts of pre-service teachers can be
structured on the basis of professional knowledge models. This applies both to
structuring using the TPACK model and the PCK model. Two aspects in par-ticular
can be identified as developmental influences: practical experience in school
and in the subject area and also the effects of social and dimensional comparison
processes. However, the perceived relevance of the respective dimensions of academic
self-concepts acts as a modera-tor, particularly with regard to the effects of
comparison processes. Concludingly, the research methodological and practical
implications of the results for higher education are discussed.'

text: "Abstract\r\n Time-resolved momentum
microscopy is an emerging technique based on photoelectron spectroscopy for characterizing
ultrafast electron dynamics and the out-of-equilibrium electronic structure of
materials in the entire Brillouin zone with high efficiency. In this article,
we introduce a setup for time-resolved momentum microscopy based on an energy-filtered
momentum microscope coupled to a custom-made high-harmonic generation photon source
driven by a multi-100 kHz commercial Yb-ultrafast laser that delivers fs pulses
in the extreme ultraviolet range. The laser setup includes a nonlinear pulse compression
stage employing spectral broadening in a Herriott-type bulk-based multi-pass cell.
This element allows flexible tuning of the driving pulse duration, providing a
versatile time-resolved momentum microscopy setup featuring two operational modes
designed to enhance either the energy or time resolution. We show the capabilities
of the system by tracing ultrafast electron dynamics in the conduction band valleys
of a bulk crystal of the 2D semiconductor WS2. Using uncompressed
driving laser pulses, we demonstrate an energy resolution better than (107 ± 2)
meV, while compressed pulses lead to a time resolution better than (48.8 ± 17)
fs."
